Learning from Others I’ve always used the various tradeshows, conferences and other industry events that I attend as a way to get a barometer of where the industry stands, as well as to do research from some of the best resources I can find: you, our reader. So I paid particular attention when our September/October 2016 cover person, Tye Leishman, dropped by our booth during the recent CIPHEX West show in Vancouver (check out the details of the show on page 38). Tye mentioned that he had just met with a business development and best practices organization, and that he was impressed with what he had seen. He’s not the first contractor I’ve heard from who has found value in such organizations, be they formal or informal in nature.

Merry Christmas from the Entire MB Team As 2017 comes into view, the crew that puts Mechanical Business together would like to take the opportunity to wish our fantastic readers, advertisers and supporters a Merry Christmas, Happy Holidays and Happy New Year. Enjoy the holidays, and we look forward

Our resident business management guru to catching up with you again in 2017. Roger Grochmal (whose current column can be found on page 64) has written about the benefit of peer-to-peer learning opportunities many times. Something that I admire about Roger is that he’s not afraid to admit that he can’t know it all. That’s why he surrounds himself with a strong team that he can trust will guide him to the paths that will carry his company forward. And he reaches out to other contractors to learn what’s worked, or hasn’t worked, for them. He’s also always willing to share. His attitude reminds me of something that I heard Wayne Gretzky say a number of y g To p p years ago. paraphrase him, The Great One explained that one of the things that pushed him to improve everyy day was tthe fact that on any given night there was someone a littlee better better than him im. Now, Wayne had more good nights on the ice than him. a y other an othe h r NHL play any player, but even he knew there were people out there that he cou could learn from. And that’s what made him the busiin best in his business. S metiimes we forget that there are others who are willing So Sometimes t to share what they know, so we slog through challenges or try implementi implementing systems without the advice that’s there for the asking. So Sometimes all we need to do is find a mentor and pick their brain for a little while.

SAIT Celebrates 100 Years IPVF Council Tours Recycling Plant

The Southern Alberta Institute of Technology (SAIT) celebrated its centennial year in October. Calgary mayor Naheed Nenshi declared October 16 SAIT Day and the Langevin Bridge and Calgary Tower were lit in SAIT colours—red, purple and blue—until midnight. “SAIT has an incredible history of innovation and putting students first,” said SAIT president and CEO David Ross. “It’s an approach that began 100 years ago and is what we do to this day.” The college celebrated with a free barbecue, a giant cake, guided tours and fireworks.

Members of the CIPH IPVF council enjoyed a tour of the New Forest Mills recycling plant in Scarborough, Ont., in late October. New Forest Mills operates 24 hours a day, 365 days a year, recycling approximately 1,000 metric tons of cardboard per day. Tour attendees saw raw recovered cardboard re-pulped in over 1,000 gallons of water per ton of material, before being formed, pressed, dressed and finished. ciph.com

Worst Washrooms

HFC Agreement Reached The UN and all 197 signatories to the Montreal Protocol reached an historic, and legally binding, commitment to limit global HFC use in October, eliciting congratulations from numerous refrigerant manufacturers and industry associations. “Honeywell congratulates the Parties to the Montreal Protocol for the successful negotiation of the groundbreaking amendment to phase down the use of HFCs,” said Marie Li-Ying, Honeywell’s business manager for fluorine products and the chair of Refrigerant Management Canada. “The amendment is one of the most significant steps the world can take now to deliver on the goals of the Paris Agreement, which aims to limit the global temperature increase to 1.5°C above preindustrial levels.” Li-Ying affirmed her company’s commitment to helping countries reduce GHG emissions by adopting environmentally friendly refrigerants. “We are investing nearly $900 million in R&D and new capacity, and forming strategic commercial partnerships, to provide the broadest possible portfolio of solutions available today to help countries achieve aggressive goals to reduce greenhouse gas emissions,” she said. honeywell-refrigerants.com refrigerantmanagement.ca

Mechanical Business is collecting photos of some of the worst washrooms from around the world. So next time you run into an unsightly bathroom while you’re on vacation, on the jobsite or out on the town, grab your smartphone and take a picture.

Cutting the Cord Prompt Payment Bill Delayed The Senate adjourned debate on Bill S-224, the Canada Prompt Payment Act, in October. Currently at second reading, the bill was introduced by Manitoba Senator Don Plett, a former plumbing contractor. If passed, it would ensure that contractors and subcontractors working on federal government construction projects are paid in a timely manner. Plett introduced the bill at second reading in April, saying at the time, “Delay in payment is the number 1 reason small and medium sized businesses in the construction industry are going out of business in Canada.” Pictured here, Plett (centre) introduced the bill at second reading. parl.gc.ca

Milwaukee Tool’s Cut the Cord contest is currently underway, offering contractors the opportunity to win a variety of weekly and monthly prizes, as well as a grand prize tool collection valued at $10,000. Entrants are invited to submit photos of their Milwaukee tools at cutthecordcontest.ca. They can then share their entries with family and friends to get the most votes. A Milwaukee M18 cordless tool kit will be awarded to the entry with the most votes. The contest runs until January 31, 2017. cutthecordcontest.ca

John Goshulak, vice-president of sales and marketing with WeilMcLain Canada, was introduced as the most recent steward of the Carlson-Holohan Industry Award of Excellence at the AHR Expo in Orlando earlier this year. And while he himself was surprised at the honour, the recognition comes as no shock to those in the hydronics field who can attest how fitting a choice he is.

PLUMBING

PLUMBING FOR PRESSURE ZONES I

remember when I was a young newlywed. We were renting a 60-year-old bungalow in southwest Calgary shortly after I had received my journeyman ticket and Red Seal. It was in February, just around Valentine’s Day, and I knew I had to remember two things: make sure all the mechanicals in the house were working and buy a Valentine’s gift. There were two significant problems my wife began to complain about after we moved in. Our clothes didn’t seem as bright and clean as they should be, and she also thought the dishwasher was broken, because we always ended up with stained dishes. shes. (Maybe that was because I always bought the cheap detergent.) I did what any good husband and would do: I agreed with her, butt didn’t do much else. At some pointt I finally broke down and bought the he most expensive laundry and dishwashing shwashing soap I could find, just to appease her.

OUT THE SUDS As a plumbing P.I., my first step when I decided to get to the root of our appliance problems was to take a look at the basement laundry in more detail. I knew the laundry tailpiece was just lying on the floor draining into the floor drain. It made a pile of soap suds around the neck of the floor drain, but so what? They were only suds, I thought. I put the new washing machine through a few cycles just to see if it was working properly. As it went through the rinse cycle it did seem to push o out some suds and the water wasn’t that dirty. I then went we to the dishwasher and ran it through a few cycles. The were still stained. As I looked under the sink, I noticed that glasses w the dishwasher’s dishw 3/4” black rubber hose was not installed into the continuous waste under the sink. The drain hose disappeared into continuo the cabinet cab floor and then ran into the basement. In the basement, I took a few ceiling tiles out to expose the ceiling. Lo and behold, I discovered the hose pipe hooked into cei a P-trap below the floor, which was then piped into the stack in the basement. Th There were no leaks or backups, but I did remember that ev every time I installed a dishwasher I had to install the drain hose as high as possible under the counter and hook it into ho the continuous waste upstream of the kitchen P-trap. th continues on page 22

SAVINGTHE DAY To complete my story, I decided to reinstall the hose correctly above the floor and tie it into the food disposer, which was installed upstream of the kitchen P-trap. After that, I ran the dishwasher through a cycle full of dirty glasses and—voila!— out they came shiny and crystal clear. My wife would be so happy. Maybe I wouldn’t have to buy her a Valentine’s gift after all!

that a dishwasher’s hose ed must be installed as high as possible, ible, it must be the same for a washing machine. ne.

By now I was in Superman detective mode, so I figured I might as well get in my wife’s good books and fix the washing machine problem too. I might not even have to get her a birthday gift, let alone something for Valentine’s Day!

So I broke out the floor and installed a wye in the branch. I ran a new 2” ABS BS drain over and put a stand pipe e complete with P-trap up the wall 36” high. This modate our new would accommodate washing machine’s ne’s wash cycle, keeping the water ater volume nice and full, and nd letting the pump push the e water up the hooked drain hose and down the 2” standpipe.

I returned to the scene of the crime, where a brand-new washing machine sat defiantly in the dark concrete corner right in front of a suds-spewing floor drain. I figured if the code said

Sure enough, it worked. Clean dishes, clean clothes, and I even bought my wife a Valentine’s gift with all the money I saved buying cheaper soap!

I learned that the reason we install dishwasher hoses as high as possible is to prevent the dishwasher from gravity draining. Otherwise there won’t be enough water volume during the rinse cycle, hence, dirty or stained glasses.

NATIONAL PLUMBING CODE:

SUDS ZONES IN BUILDINGS In a commercial building, we would typically multi-storey wet-vent washing machines as they are only two-fixture units, and you are allowed to wet vent up to four-fixture units per storey above the first storey, as per the 2015 National Plumbing Code.

Where a domestic dishwashing machine equipped with a drainage pump discharges through a direct connection into the fixture outlet pipe of an adjacent kitchen sink or disposal unit, the pump discharge line shall rise as high as possible to just under the counter and connect: a) on the inlet side of the sink trap by means of a Y fitting, or b) to the disposal unit.

But this would become a problem as new washing machine pumps would discharge soap suds 40 times the diameter of the wet vent, up and down the pipe. This meant that if you installed a 3” wet vent, the soap suds would travel up and down the wetvented stack for 10 feet after leaving the washing machine.

Watco 901 Innovator®

If any other plumbing appliances were installed in that suds zone area, they would leave suds backing up through sink drains. This would not only present a cosmetic issue, but the suds would eventually solidify and plug all the vents. The 2010 Canadian National Plumbing code included a new table—2.4.10.12. Maximum Permitted Load from Fixtures with a Semi-continuous Flow—to size the fixture unit load and P-traps for commercial washing machine drains based on their litres-per-second pumping output. This meant larger pipes would be installed for high-output pumps. Other recommendations were made in the appendix of the code (A-2.4.2.1.(4) Suds Pressure Zones). This advises that highsudsing detergents used in clothes washers produce suds that tend to disrupt the venting action of plumbing systems and spread throughout lower drains. One solution is to create a suds zones stack separate and downstream from all other stacks. This serves to keep the washing machine multi-storey wet-vented stack separate from all other fixtures and stacks. It’s also advisable to keep all fittings, such as wyes and 45s, as streamlined as possible, increase your building drain one size larger than normal and, finally, install check valves on all the washing machine fixture outlet pipes that are tied into that suds zones stack.

PROJECT PROFILE By Ada m F r e i l l

Oilers

RINK

TURNING HEADS IN EDMONTON

oung NHL phenom Connor McDavid is lighting things up in his first year as the captain of the Edmonton Oilers, but even he might understand if a visitor to Rogers Place pays more attention to the building than the team.

Y

The new home of the hockey club is an impressive 819,200 sq. ft. structure that sits on 9.5 acres of land and features a pair of NHLsized rinks, seven levels of seating for 18,347 fans, a 30,000 sq. ft. dressing room for the team, and a 400-ton ice plant designed to create some of the best ice anywhere. That’s a big step up from the team’s former arena, the 497,700 sq. ft. Rexall Place. The new structure, which is the centerpiece of the city’s new 25-acre ICE District, actually approaches the size of a stadium, rather than an arena. Of course, Rexall Place has a great reputation for quality ice, but the team working the ice system at the new building is creating its own buzz for ice quality.

Rogers Place, By the Numbers 24

“We know what the history of Rexall’s ice quality has been,” says Jason Rimmer, the assistant manager of engineering with Oilers Entertainment Group. “We have our own target to try to be the best in the NHL – of course everyone wants to be the best in the NHL.”

Tempering the Ice One of the most striking differences when skating on a pro-level ice surface, in comparison to most local rinks, is the hardness of the ice. At Rogers Place, the ice undergoes a unique tempering process that helps with the quality of the surface. “We warm the slab and the ice up to just below the melting point,” explains Rimmer. “We normally target 29°F in the slab. “We flood the ice, and flood and scrape and flood and scrape it. You are trying to saturate the ice, and you keep doing it until the ice doesn’t absorb any more moisture.” At that point, the ice crew brings the ice temperature down to 22ºF at a very controlled rate – generally about 0.4 degrees per hour.

BUILDING GOOD ICE

OF THE RINKS

At the heart of the ice plant at Rogers Place are four screw compressors that deliver a total of 400 tons of refrigeration that is split between the two rinks, the NHL surface and the attached Downtown Community Arena (also NHL-sized). The main surface sits on a slab containing almost 10 miles of 1-1/4” schedule 40 steel tubing on four-inch centres, while the community rink uses 1” polyethylene piping. The ice plant is an ammonia-based system, with a heat exchanger in place so that glycol runs through the slab piping for both 200-ft.-by-85-ft. rinks. Creating good ice starts by getting good information about system conditions, so sensors are included on the supply and return for each rink, and the system also makes use of in-slab sensors for each surface. “In the NHL rink we installed an additional eight sensors that we’ve just put on the top of the slab, and we also have two infrared cameras on the NHL rink, and one on the community rink,” adds Rimmer. “The advantage with our sensors is that we can tie them right into our DDC system. That way we can control right off those sensors, and we can base it on the lowest, the highest or an average temperature reading of those eight sensors.”

ANATOMY

Creating a fresh ice surface from a bare slab is a process that can take several days as thin layers are built up to reach a target ice thickness of an inch and a half. The engineering crew cools the slab floor to between 15 and 16°F before hitting it with water. That allows each layer to freeze fairly quickly between building the layers. “It can take about four days, depending on how much of a hurry you are in,” says Rimmer. “We had a week to build it on our first go-around.” During a game, a typical flood will go through 100 to 130 gallons of 140°F water, but even that takes a bit of engineering control. “When we are running a game here, we will throw 300 tons at the NHL rink during the pre-cool before the period ends, so that when the water hits during the flood we are freezing as quickly as possible,” explains Rimmer. Good ice requires a combination of slab temperature control, and appropriate ambient temperatures and humidity. “Our targets are 22°F on the surface for the ice, 40 per cent relative humidity, and 57°F for air temperature.” And while most arenas fight the issue of having too much humidity, that’s not an issue in Edmonton. “For us, our biggest advantage is that we live in Edmonton and it gets drier than the Sahara in the winter here,” says Rimmer, who explained that the team is monitoring the ice during this first season to determine whether they might need to add a humidification aspect to the existing HVAC system. The arena is equipped with a dehumidification system, but mainly for shoulder seasons. “With most hockey rinks, humidification is the last thing you want to add, but that is a reality of being in Edmonton,” he states. With the compressors rolling, “When the humidity gets too low, you start there’s waste heat that has to sublimating your ice and the ice shrinks, go somewhere, and rather than and you could potentially have challenges allowing that to dissipate into from that too. the atmosphere, the engineering “That’s something that we’ve talked team is finding creative ways to about and we are going to go through the use that heat energy. first year and see how it goes. If it does get too low, we are going to look at some “Right now we are taking the humidification options for next year.” waste heat and recovering it into the parkade,” explains Rimmer. “It has been proposed to incorporate our domestic hot water into our heat recovery as well. With all four compressors operating, we are generating more than six million BTUs per hour, so that’s some substantial heat, which should result in some substantial savings.”

SIMPLIFIED BAS SOLUTIONS FOR SMALL COMMERCIAL BUILDINGS E

ven as building automation systems (BAS) become increasingly utilized in larger commercial buildings, they are often overlooked as an option for small- and medium-sized commercial facilities. In some cases, it is because they are perceived as too expensive or complicated for the application. However, automation is becoming a more viable option to consider for a range of building applications. Wireless technology now makes it easier than ever to manage all types and sizes of buildings more intelligently and efficiently, optimizing business performance. This makes the detail and sophisticated control of a BAS a cost-effective and easy-to-use solution for smaller buildings, including commercial properties, hospitality and retail applications. Building automation provides an ongoing connection to how the building and its systems are performing — both for building owners and contractors. Contractors can leverage building automation to improve service calls and provide insight to building owners down the road.

OPTIONS FOR LIGHT COMMERCIAL APPLICATIONS There are numerous options to consider for controlling HVAC systems in light commercial buildings. They include programmable thermostats, web-enabled thermostats and simplified building automation. Each of these technologies should be evaluated before arriving at a decision. • Programmable thermostats are easy to install and offer low hardware costs. However, conventional thermostats are individual units that cannot be integrated with other devices or building systems such as lighting and security. Units are programmable, but each unit must be manually adjusted when changes are needed. • Web-enabled thermostats can offer interoperability but are often largely focused on residential automation proprietary controls rather than commercial building open standard protocols. This can limit the ability to integrate with other HVAC systems, or other types of systems such as lighting and security. Also, this technology is similar to programmable thermostats, in that each schedule for each piece of equipment must be adjusted individually. • Simplified BAS solutions available on the market are built on platforms that support traditional open standards for commercial applications. This makes integration easier, so multiple building systems such as HVAC, lighting and security can be managed and adjusted via one single interface through the BAS. These systems can offer a range of functionality and control, including customizable alarm notifications, 365-day scheduling, area control, and optimal start and stop features. Available BAS technology also enables the utilization of energy management solutions, for a link to additional services that make it easier to monitor building data and gain insights into building performance and usage to drive better service and improvement efforts.

BAS BENEFITS DRIVE EFFICIENCY Among the numerous options, BAS systems provide an easyto-use single point of control for multiple building systems and zones, so building owners and managers can run their buildings smartly and more efficiently. Available BAS solutions also allow remote access to these control capabilities, for web-enabled enabled access to building systems from nearly anywhere.

Contractors can get remote building access — with customer permission — that allows them to see issues or problems prior to a service visit, so they can prioritize service work for the most critical issues and come prepared with any necessary parts for maintenance. A BAS also enables contractors to receive email alarms and alerts, so they can notify customers of issues before impact occupant comfort. they imp Utilizing wireless communication technology with a simplified BAS solution can shorten the installation ccycle and help keep projects on track and on budget, putting this type of building technology within reach for more facilities. It also offers greater flexibility for the future, as technology and capabilities change.

HVAC rooftop equipment is becoming more advanced with new technologies, which helps optimize performance and significantly improve the bottom line. Taking advantage of these highefficiency, variable-speed technologies in rooftop units is made easier with advanced building controls. This helps drive savings and allows building owners to get the most out of the new technology in rooftop units. Simplified BAS solutions also provide greater insight and enable access to a wealth of data regarding what’s happening in a building. For contractors, this additional connection to the building and its systems provides an opportunity to act as a proactive partner in maintaining and servicing the b building ildi — for faster troubleshooting and efficient resolution of issues.

Dan Holohan is an author, speaker, steam heating expert, and founder of heatinghelp.com, a highly regarded industry site that shares information about heating systems old and new. He can be reached at dan@heatinghelp.com.

whys HISTORY THE

OF HYDRONIC

W

e’ve come a long way since the days of gravity hot water heating. The physics haven’t changed, but the systems sure have. Ever wonder how some of the equipment we install, and how and where we install it, has evolved over the years?

THE WAY WE WERE Trapped air was a challenge back in the day before we had effective air separators. The Dead Men would slope their big pipes upward to encourage the air that came out of solution (when the water got hot) to rise to the open expansion tank up there in the attic. They would usually pipe their cast-iron radiators in the bottom and out the bottom because, without benefit of a circulator, the hot water would rise to the top of each radiator as the colder water fell from the radiator and left through that lower exit hole. The only way to get the air out of those big castiron radiators was to manually vent them, and the Dead Men had to do that one floor at a time as they filled the system.

M e c h a n i c a l

B u s i n e s s

Boilers wound up on the roof not because builders were afraid of floods, but because the buildings were tall. Having the boiler at the top of the system made sense because the pressure up there needs to only be about three psi – the same pressure you would need at the top of any hydronic system. That’s the pressure that allows you to vent air from the high point, and to keep the water from flashing to steam, should it be hotter than 100°C. Put the boiler in the basement of that tall building and the pressure is going to be much greater. You may have to invest in a high-pressure boiler and all that goes with that. Of course, if you heat with oil, it’s going to be tough getting the delivery truck up on top of the building. Enter the use of natural gas.

BOILER ON THE ROOF?

continued from pageHVAC 32 HIGH-PERFORMANCE HYDRONICS

They filled those earliest systems through a funnel that was at the very top of the piping. Imagine having to carry that many buckets of water up all those stairs. And you think it’s a pain when you forget your smartphone in the truck and have to go back to grab it. Gosh.

PROPER PLACES

When city water pressure showed up, the Dead Men filled their systems from the basement, and they used an overflow pipe that ran from the open expansion tank to the basement. They’d fill until they got overflow, and then they’d have to dump some water from the boiler to bring the level in the tank to just the right spot. That gave the water a place to expand once it got hot.

Eventually automatic water feeders arrived and that gave installers a way to manually vent radiators without having to monitor the flow of water into the system. Factories set the feed valves at 12 psi, because that’s what we need in a typical two-storey building. If the building is taller, you increase the pressure, and then pump up the compression tank’s air pressure to match that water-fill pressure.

Altitude gauges showed up next, and these did away with the need for an overflow pipe. These were simply pressure gauges with a modified face. The Dead Men would measure the altitude from the manual fill valve to the centre of the expansion tank in the attic. They’d set the movable red needle on the altitude gauge to that height, and then they’d let the water enter. As it rose in the system, the water pressured the gauge. That second needle would move. When it met the red needle, the system was filled. Simple! Of course, if they added too much water to one of their systems, it would just overflow from the tank and out onto the roof. That was embarrassing but it did no more harm than rain on the roof. A bigger worry was the air temperature up there in the attic. During the dead of winter, the water in the open tank was liable to freeze, and that presented a danger since the frozen water blocked the expansion space. That’s why they moved the tanks to the basement around 1915, giving us what we came to call the compression tank.

They learned that the best place to install the feed valve was right at the compression tank because the tank is the one point in the system where the pressure never varies. Fill at that point and the circulator won’t be able to trick the fill valve into feeding when the circulator starts.

Fast Fact: A column of water that is 70.4 cm (2.31 feet) tall will exert 1-psi pressure at its base, and that’s what the altitude gauge showed.

So an expansion tank is open to the atmosphere, and a compression tank is closed to the atmosphere. The water expands; the air compresses. The rest is history.

ANTIQUE AQUASTATS The first aquastat sat atop the boiler. It was a bellows that sensed rising pressure. Attached to the top of the bellows was a fulcrum attached to a short steel bar, weighted on both sides. Attached to the weights were chains that ran through ceiling-mounted pulleys. These chains controlled the draft above and below the firebox. As boiler pressure rose the bellows expanded, shifting the weights, which moved the chains that closed the dampers. The fire died down; the pressure sank. The bellows contracted, shifting the weights once again, and moving the chains to open the dampers. Up rose the coal fire!

Always pump away from the compression tank. That way the circulator will always apply its full differential pressure to the system. That busts up trapped air bubbles and brings them back to the air separator. Your days of bleeding radiators will be over, and that’s nice. The air separator belongs either where the water is hottest, or where the pressure is lowest. This is because of Henry’s Law, which tells us that gases dissolve in liquids in proportion to pressure and temperature. So the air separator can be near the boiler (the hottest place), or up at the top of the system (the lowestpressure place). But since all the water has to pass through that big supply pipe at the boiler, this is the most sensible place to put your air separator.

FACILITIES AGREEMENTS:

LEVERAGING PROFESSIONAL SKILLS & TOOLS Regular Business, Steady Profits

H

air-clogged shower and tub drains. Backed-up toilets. Kitchen grease stoppages. They’re all common consumer plumbing emergencies. But commercial and non-profit facilities – schools, restaurants, apartment buildings, hospitals, hotels, supermarkets, personal care homes, factories and more – suffer similar troubles, too. Maintenance agreements with facilities such as these can help expand your business. And plumbing contractors across North America are doing just that.

SOLVING KITCHEN CONUNDRUMS Serious kitchen drain stoppages at Southwest Medical Center in Oklahoma menaced operations and sanitation. Worse, a parade of plumbers couldn’t cure the chronic quandary. Couldn’t, that is, until Larry Linn of Linn’s Plumbing sprung his drain cleaning equipment and expertise into action to spot, and solve, the true trouble. Using one of his lightweight, compact video pipe inspection systems, he first pinpointed the problem: a broken cast-iron pipe.

Many larger facilities hire sizable maintenance staffs. Smaller ones, by contrast, employ few custodial personnel. Either way, unless their rosters include seasoned plumbing and drain cleaning professionals – and they maintain proper equipment arsenals – they probably can’t handle many of the common drain cleaning emergencies that arise in their facilities. That’s where you come in. Paraphrasing Ghostbusters, “You got the tools! You got the talent!” Many savvy plumbing and drain cleaning pros are establishing regular service agreements with schools, apartment buildings, healthcare providers and other facilities to handle recurring drain cleaning problems.

“Six other competitors just snaked debris around, never fixing the underlying mess,” he says. Linn cleared the line with a heavy duty drain cleaner designed to clear roots and other difficult clogs with 100’ of 5/8” innercore cable optimized for long, tough jobs.

The DVD recording of the collapsed line convinced Southwest Medical to replace, rather than repair, the kitchen conduit. In clearing the hospital drain, his heavy duty drain cleaner also retrieved a broken cable with cutter head from a competitor who irresponsibly left it there. “That made blockages even worse,” Linn notes dryly.

“Teaming both tools confirmed our thoroughness and professionalism,” he says, smiling. “The construction supervisor was amazed at how quickly, and cleanly, we got that drain flowing!”

His camera inspection system offers everything necessary to troubleshoot 2” to 10” lines. The self-levelling colour camera keeps pictures upright, letting customers clearly follow the action. continues on page 42

The push-rods he uses are designed to protect wiring from cuts and abrasion, and recording options include DVDs, SD cards, or Wi-Fi to record on a tablet or smarrphone. His heavy-duty drain cleaner can be used on 3” to 10” lines up to 200’ in length. Linn has six of these heavy duty drain cleaners for his four crews. “It’s great for one-man use,” he says. He also likes the closed-drum design for medical and dental offices. “Cleanliness is critical to those customers – and to our reputation.” Having a proper array of equipment, plus experience solving similar clogs, also gives Linn a leg up on his competitors. He was able to beat the competition for the hospital kitchen job and still stay profitable. Not only that, but he promised completion in five days but wrapped up the job in three.

Sometimes a snake is the right tool, and sometimes a stream of water will do the trick, but another innovation that’s pulling its weight in the field is a ligthweight hand-held device that safely, quickly and cleanly clears clogs with a powerful burst of compressed air.

Grease clogs can plague kitchen conduits. But the right drain cleaning equipment, Chris Fantauzzo contends, turns those problems into profits.

That’s why Fantauzzo added a portable 3,000 psi, 4 gpm gaspowered water jet to his company’s mix of drain-cleaning and inspection solutions.

“We do a lot of fixed-rate commercial contract work,” he says. “So speed is important to maintaining our profitability: the longer we take, the less we make.” One regular Pro-Tech account, a large pastry shop, developed a third-floor grease clog that loosened, traveling to an inaccessible portion on the building’s ground level and backing up a large, 30-gallon sink. Since the air-powered device will work through standing water, he turned to it to fix the problem. “We just pumped up the unit and blasted the blockage away,” he recalls. That sort of performance considerably enhances Breton’s productivity in apartment situations. “We can service a 32-unit building in less than half the time it takes us to do the same work with cable machines, and it’s a lot cleaner, too! Managers and residents love it.” It’s great for restroom emergencies, as well. “It gets you through bad situations – fast,” notes Breton. “Our customers really like that!” Marty Silverman is the vice-president of marketing with General Pipe Cleaners. He can be reached at mjs@generalpipecleaners.com.

B u s i n e s s

SOFT STOPPAGES

And all those problems, he says, are commercial business opportunities.

To many a pro, it’s tailor-made for clearing recurring drain cleaning problems in, for instance, restaurants, schools and apartment buildings. Just ask Alain Breton, president of Pro-Tech Drains in Quebec.

“Health inspectors want restaurants to clean grease traps regularly,” explains the owner of Mercer Drain Cleaning Service in New Jersey. Bar owners and municipal authorities are also among the types of customers who suffer from grease, sediment, sand and ice blockages.

“When a drain cleaning cable goes through grease, grease closes behind the cable, still leaving the line clogged,” he explains. But the high pressure water jet hits soft clogs with a wall-to-wall stream of high-pressure water and flushes them away. One of his competitors recently tried clearing a cast iron line, but the blockage returned a few days later. “The guy just snaked through a whole mess of toilet paper, which almost immediately re-clogged the pipe,” he recalls. “We blasted the blockage downstream with our water jetter and permanently removed the wad from the trap.” His gas-powered jetter has on-demand pulsation to help the hose glide easily around tight bends and down long lines. Water jets are indispensable weapons against grease, sand, sludge, and ice blockages. Fantauzzo tasks his gas-powered water jet for 4” and larger lines. He also owns a compact, portable electric water jet for smaller, 1-1/2” to 2” lines. His arsenal of tools also includes a portable video inspection system; multiple large line drain cleaners for tree roots and other stubborn stoppages; a mid-size drain cleaner for small floor drains, vents and stacks; and multiple hand-held power drain cleaners with automatic feeds to clear clogged sinks, tubs and laundry drains. Fantauzzo, like Larry Linn, teams tools for optimal productivity. His crews can precisely spot and diagnose problems with his inspection camera , and then use the right drain cleaner for the job.

CELEBRITY ENCOUNTER By Adam Freill

hen American Standard launched its ActiClean self-cleaning toilet earlier this year, the company linked up with much-loved germophobe and practical joker Howie Mandel. Mandel, who grew up in the Toronto suburb of Willowdale, accidentally found himself in the position of being an “ambassador of mental health” after revealing his own challenges during an interview several years ago. Since then he’s embraced the cause of positive mental health, and encourages others to be open about their own mental health issues, in hopes that society loses the stigma associated with it. “A lot of people have a soapbox. I happen to have a throne,” he joked during an exclusive interview with Mechanical Business, right after he inquired about being the centerfold in the magazine. “I never dreamed that I would be a model.”

Being connected to a toilet was a natural fit for the funnyman, but pitchman duties aside, he liked what he saw of the technology from the get-go. “I know they approached me because I have become a renowned germophobe,” he says, “but I would have one even if I didn’t have anything to do with k db f t th b d American Standard because I am irked by th the fact thatt anybody has to hold a brush and clean their toilet… In my house, everyone’s hands are clean because they don’t clean the toilet. They don’t have to.”


Removing the Stigma

Howie, the High School Foreman

Bring up the topic of mental health in a group and it’s not uncommon for an uncomfortable silence to occur, but it need not be that way, says Mandel. “I am a renowned proponent of removing the stigma of mental health issues,” he says. “Growing up in the ’50s, nobody talked about it, nobody really did anything about it, and I just think that [talking about it] is the answer to all of our problems.” Howie discovered just how prevalent an issue mental health is after divulging some of his struggles during a radio interview. “Accidentally, I blurted out what my issues were, but as it turns out I am not the only one with issues. Every human being has issues. You don’t have to be diagnosed with something that has an acronym or has letters in front of it. You just have to be a human being,” he explains. “I suffer from anxiety and depression, and I made jokes because laughing was just a lot easier than crying, but I battled, and it is a battle that I am involved in every day. “Life is a fight, and I am having a good time in this battle, and it is well worth battling for, but we have got to talk about it – whether that is in a plumbing magazine, or with the guy next to you on the bus, or whether it is me on stage,” he says. “If we just talk, and we are all open, and we all know that we are all awkward, and it is weird and it is funny, and even if the beginning of the conversation is, ‘You know, they have a toilet where you can just push one button and walk away,’ we just have to communicate about how we feel about things and how we do things, and things will be better.

The seeds of Howie Mandel’s comedy career were sown long before he was discovered during an open mic night at a Los Angeles comedy club. His practical jokes were a contributing factor to his being asked to leave his school a little bit before graduation, and one of his best capers was his attempt to update his high school. “I authorized, through the Yellow Pages at the time, people to come out and measure and give bids on an addition to the library,” he says.

“We are all awkward. We are all weird. We are all mental. And we need to acknowledge whatever our mental issues are. They are just what make us human.”

From his classroom on the third floor, he marveled as a crew arrived on the scene. “I was looking down onto the field and I could see these guys measuring. And then I saw the principal wander out onto the field, and then this animated conversation.”

Soon enough, Howie was called down to the office, where his principal asked: “Did you authorize a company to put an addition onto the library?” “I answered very seriously,” says the funnyman. “No, I am getting three bids. I am a little more responsible than that. I will not give my authorization without getting three bids.

“And there’s always help.” At work, many of us feel that our state of mental health needs to be hidden, but that just adds to the stigma, and doesn’t help the person who is struggling internally, Mandel notes. “If you hurt your back as a plumber, a million people will have a chiropractor, or you can go and get a massage, but if you just can’t function because there’s a lot of pressure, or you just became a parent, or somebody in your family was diagnosed with something traumatic, there’s nobody in place just to talk to,” he explains.

“And one thing leads to another, and now I am in the most popular plumbing magazine in the world. I wish that principal was around today because I would show up at his office and slap this magazine down on his desk and say, ‘Ha!’”

“They tell you, ‘I need to get a retainer because my teeth are crooked.’ They’ll tell you their back hurts or their ankle hurts, but nobody will tell you, ‘I can’t function. I’m anxious and scared, so I can’t go to work today.’ They won’t tell you that,” he says. “I don’t understand the difference. We go take care of our dental health and 90 per cent of the time there’s nothing wrong – we just go for a checkup. But nobody goes and gets a checkup by just talking to somebody.

Did you know?

“Just like dental health, we have to take care of our mental health.”

Sunday, December 18th at 8 p.m. ET/PT on Global.

OPPORTUNITIES FOR HVAC CONTRACTORS

I

’m sure many of you reading this have heard customers, clients, or even friends and neighbours mention the dreaded R-word...radon.

I’m also sure many of you have not. It’s remarkable how an issue so well-known and addressed in both the public sphere and in the building and housing industries in the U.S. and Europe has taken so long to gain widespread attention here in Canada. Regardless, it’s here now and it’s only getting bigger. Radon is an important issue for homeowners and builders alike, and it presents some great potential opportunities for HVAC contractors in the know.

WHAT IS

radon

Radon is a naturally occurring soil gas that is invisible and odourless. It is present in rocks, soils and water, and it gets released into the air – sometimes outside, where its concentration is negligible, or sometimes inside of our houses through our foundation walls or slabs. Inside, it can reach dangerous levels. The alpha particles emitted as radon particles break down are the real danger here, not the radon itself. Alpha particles that hit someone’s lungs can sometimes damage the cells. This may potentially lead to lung cancer. Radon is not an immediate danger, like a fire or natural gas leak, but it is a danger more akin to the risks associated with years of smoking. To give a picture of the health risk, living in a home with concentration level of 300 becquerels per cubic meter (Bq/m3), not at all an unheard-of level, is the rough equivalent of smoking a pack of cigarettes a day in terms of damage to lung tissue. As of now, roughly 16 per cent of lung cancer deaths are attributed to radon exposure, though this is very likely an underestimate.

M e c h a n i c a l

B u s i n e s s

ACCEPTABLE RADON LEVELS In Canada we measure radon concentration in becquerels per cubic meter (Bq/m3), which you can divide by 37 to convert to the U.S. unit of choice, picocuries per liter (pCi/L). The average home in Canada contains concentration levels of 41.9 Bq/m3 of radon, and the average outdoor concentration is around 10 Bq/m3 (that’s right – not even outside air is completely safe). According to a 2012 estimate, almost seven per cent of homes in Canada have radon levels of 200 Bq/m3 or more. This is the current actionable level (the point at which mitigation measures are recommended) set by Health Canada. This was lowered from 800 Bq/m3 in 2007. A more recent random sample of 131 homes in Guelph, Ont., revealed that 18 per cent had concentrations above the actionable level. For comparison, the Environmental Protection Agency’s actionable level is 148 Bq/m3, and the World Health Organization’s is 100 Bq/m3 – half that of Health Canada. A 2014 study concluded that approximately 233 lung cancer deaths per year could be prevented in Ontario if all houses with concentrations above 100 Bq/m3 were remediated. continues on page 50

Behind Every Successful Contractor There is a Great Partner.

Goodman is mine. When it came time to find a strategic partner to help take his company to the next level, Mike Martino knew there was only one choice: Goodman. With Goodman on one side and “the best employees in the business” on the other, Martino HVAC became Ontario’s premier HVAC contractor. Service calls were significantly reduced and, along the way, Martino picked up many industry honours including the prestige of being named BILD’s “Trade Contractor of Year” an unprecedented three times. Martino won’t give you all the secrets to his success, but one he’s happy to share is the importance of a great product partner. As Mike puts it, “Goodman is mine.”

Radon

MITIGATION There are a few ways to mitigate radon in a building with high radon concentration levels.

Measuring

RADON CONCENTRATIONS There are areas that are much more prone to high radon levels than others, though concentrations can vary dramatically from house to house, and even fluctuate day to day and season to season. There is truly no way to know the level of radon in a home without measuring that specific home, ideally with a long-term testing device. With proper certification, HVAC contractors have the opportunity to act as specialists, focusing on measurement or mitigation (or both), using some familiar products and methods, as well as some new ones. In the U.S., which is years ahead of Canada on the radon scene, 33 states have already made radon measurement a requirement in each and every real estate transaction. (Yes, that is a great deal of measuring.)

There are a number of different methods & products that can be employed to measure radon levels.

There are a number of different methods and products that can be employed to measure radon levels. Basic measurement kits that show average concentration, such as the alpha track products from Radon Environmental Management Corporation (REMC), are relatively low in cost and simple to use. You just open the package and place the device in an appropriate spot on the lowest inhabited level of the house, then collect the device a few months later (or weeks later, in the case of short-term devices) to send it off to the lab and await the results.

Digital detectors are also available to provide on-the-spot readings (usually after 48 hours of measurement), but these only show averages in concentration, rather than peaks. Another type of measurement device uses air grab sampling, which allows the user to capture a sample of the air in a building and test it on the spot for fast and accurate measurements. This, however, only gives a representation of concentration levels at the moment of collection, and does not reflect the long-term average concentration levels, which is what is generally recommended before undertaking any mitigation.

50

M e c h a n i c a l

B u s i n e s s

1 2 . 1 6

Most favoured among contractors, and recommended by the World Health Organization (WHO), is subslab depressurization (SSD). This is where air is drawn from under and around the slab via a pipe and inline fan and exhausted outside. Another option is to use the existing sump-pump hole and incorporate a sealed cover connected to the pipe and fan. To depressurize an existing home, a hole must usually be cut in the slab. As time goes, builders will likely be required to install at least a rough-in pipe for future radon mitigation if needed. This is now mandatory by code in most of British Columbia, and is coming to other areas as well. For example, it is one of the prescriptive options the City of Guelph requires of all new building permits applied for after August 31st, 2015, under its Radon Gas Mitigation Program. Three other areas in Ontario also require consideration of radon when building – the City of Elliot Lake, the Township of Faraday and the Township of Hyman, all areas with a history of mining. Watch for these changes in your area. Fresh air ventilation systems (HRVs and ERVs) can also be very effective in mitigating radon, as the process of exhausting stale, radon-filled air and diluting the air in the building with fresh air lowers overall concentration levels. This method is actually more common than sub-slab depressurization in much of Europe, and we may see it gain popularity in the future here in North America as it is less destructive to the building design, taking advantage of already existing air handling systems. When used in combination with a radostat detector it also has the benefit of reducing operating costs, as the air exchange system is only activated when rising radon levels are detected, unlike an SSD, which operates continuously. There is much more to radon, and certainly many more products and mitigation methods than I’ve touched on in this article. If you are interested, I would highly recommend visiting the radon section of Health Canada’s website for more general information (www.hc-sc.gc.ca).

Protecting YOUR VFD INVESTMENT

AS THE COST OF ENERGY continues to rise, so too does the increased demand for efficiency. One of the ways many manufacturers are improving efficiency is through the use of variable frequency drives (VFDs) for electrical motors. Compared to across-the-line starters or older DC drives, variable AC drives are able to save users money by providing better motor control to operate the system at lower speeds and unity power factor. Over time, the payback from these savings reduces operating costs and provides a return on investment. However, this is only possible by ensuring the lifecycles of these units are maximized and optimized.

Here are 10 ways to protect an investment in a VFD:

Protecting the VFD investment begins before a VFD is even purchased. Factors such as performance, speed or torque control, fieldbus communications, or even inputs and outputs can often affect the model of unit needed. Taking the time to first determine the needs of your customer can often differentiate between a successful project and one that keeps you up in the middle of the night.

6

Training and qualifications.

By taking appropriate training on the equipment you are installing, you can offer proper advice and a quality install to your customers. And knowledge of the systems is of utmost importance, especially in harsh environments. Manufacturers provide minimal standards for installation and often there are local electrical regulations which also need to be met. Further, being a trained and qualified installer allows you to ensure that drives are mounted correctly, all wiring is bonded and grounded properly, the installation allows for proper airflow, and all covers and protective barriers have been reinstalled correctly.

2

Make sure the system is engineered properly.

The VFD needs to be sized according to load and ambient conditions to ensure that it can handle the torque required in all situations. Be sure to consult with the VFD manufacturer. They will have design resources available to support you.

7

Verify that your people doing the start-up and commissioning are wellversed in VFD operation.

Knowing and understanding how to properly enter the motor data, utilize PID controls and establish field bus communications will help ensure that both budgets and deadlines are met during the installation.


3

Evaluate your environment.

If the location of installation is contaminated with dust, conductive residue, debris, moisture, oil, high temperatures, or other potential disruptors, you may want to invest in a VFD that is rated NEMA 12 or NEMA 4 to protect it from these variables. Also consider temperature, altitude and humidity, and compare them to the manufacturer’s specifications. The electrical environment is also important and often overlooked; existing harmonics, stray voltages, imbalances or line spikes can cause adverse effects to your new installation. Filters, reactors and isolation transformers are other items that may be needed to ensure a properly operating environment.

8

Train onsite staff.

Having a good working comprehension of variable AC drives will help maintenance staff to better understand what is considered normal and abnormal operation. By identifying abnormalities early, they could prevent unexpected failures and downtime, and the information they provide can help with troubleshooting when the unexpected does occur.

4

Select the correct motor.

9

Perform regular maintenance.

5

Not all motors are created equal. Due to the nature of the pulse-width modulation (PWM) waveform that a VFD generates to produce a synthetic AC waveform, there are often high voltage spikes. VFD-rated motors are equipped with extra insulation and are designed to handle this. Be sure to consult with your motor manufacturer regarding speeds, duty cycle, isolated bearings, ground brushes and environment. A good motor manufacturer will work with you to verify you are purchasing the best product for your application.

Like most electrical equipment, VFD manufacturers prescribe recommended maintenance intervals that should be followed. This will allow your customer to plan shut-down times so that you can clean and inspect the unit, identify potential problems and remove any items that may be preventing the equipment from properly dissipating heat. It also allows you to chart standard operating conditions and identify if things are starting to break down, such as the electrolytic capacitors.

Specify the correct fusing, cabling and filters.

Before finalizing the installation, be sure to consult the installation manuals that come with the VFD. These will provide valuable information regarding compliant fuses and cables sizes and types (such as VFD cable), as well as any external items you may need, such as a load reactor to prevent things like reflective waves. Further, use the correct wiring and wiring practices during the installation process. A VFD cannot maintain its NEMA 12 or NEMA 4 rating if wiring practices and components of the same rating are not used.

10

Invest in recommended spare parts and review them on a regular basis.

It is one thing to purchase a spare unit, and another to actually use it. Many VFDs today have electrolytic capacitors which, if left unused for more than a year, begin to deteriorate. This may cause the unused drive to spontaneously combust when finally installed. While it is important to have extra parts like fuses and control boards, as well as spare VFDs on hand, it is just as important to regularly test and inspect them to ensure they are in good operating condition and ready for use should you need them.

It is imperative that the installation process for a VFD be followed precisely and accurately. By spending the necessary time up front, investing in the correct products for the application and conducting regular maintenance, you can rest assured that your customers will reap the energy savings and operational efficiencies of a VFD for many years to come.

Marketing with DOUG MACMILLAN

A Charitable Balance: It’s All in the Plan There is no shortage of great causes knocking on the doors off local businesses. Done well, supporting one of these causes is an age-old, mpany, win-win union. A brand builds its profile as a caring local company, while charities get the funds they need to improve the wellbeing eing of the community.

Doug MacMillan is president of The Letter M Marketing in Guelph, Ont. To reach him, email doug@thelettermmarketing.com.

Work from a Plan Building a corporate social responsibility plan provides a framework for what matters to you and your employees, and will ensure that charitable decisions align with your brand. It should also identify measures to gauge return on investment. Folks will argue that supporting charity is about giving, not getting something back; however, every single decision an owner or manager makes must consider the impact on the company. If a business is stronger and more profitable because of its community giving, it will have even more to give in the future… leading to an even stronger business, and an even stronger community. It’s neat how that works.

56

M e c h a n i c a l

Saying no is difficult when every cause seems like an important one. Who are we to say that breakfast programs for kids are more worthy than assistance for people who care for an aging parent, or that a sports team deserves our support more than an arts program? Charities are skilled at pulling at heartstrings to get a yes regardless of whether it’s a good business decision. Yet, giving to charity should be a good business decision, even though we cannot say yes every time.

How to Give When it comes to corporate social responsibility, there are generally three ways for a business to give back. Understanding the pros and cons of each approach can help a business build a plan that is right for them.

Cash donations: Aside from being listed as a donor on n a website or annual report, the advertising recognition ognition of a donation is typically minimal. The return urn on this investment – other than helping an important cause – is a tax receipt to offset the donation. Such donations are typically made without fanfare. We give because it’s the right thing to do, and because the cause matters to us. We don’t see it as a marketing investment, per se.

Cash sponsorships: Businesses looking for more recognition in the market will usually make a sponsorship pledge. This can be money or in-kind services, in exchange for brand recognition in the charity’s marketing efforts. This may come in the form of a logo on posters, banners or event brochures; a profile on the charity’s website, newsletters and other communications; or other forms of recognition typically negotiated between the business and the charity. Tax-wise, these investments are recorded as marketing expenses that reduce a company’s overall taxable profits. By and large, this is the preferred route for businesses looking to show themselves to be a caring local company. As such, it is important to evaluate the likely impact of the exposure. If you spent the same amount on advertising, would you see the same level of profile in the marketplace?

In-kind donations of time and talents: Most businesses need to put a cap on the amount of cash they can give to charity, but they can still provide considerable support to the community by volunteering or providing in-kind services. A plumbing contractor that retrofits a hospice’s aging plumbing system can treat that donation of its talents as a sponsorship and request comparable advertising value. An important bonus with this strategy: it is proven that employees experience greater job satisfaction and build new skills when they’re involved in employer-supported volunteering and community engagement. A well-constructed corporate social responsibility plan will identify its giving priorities in each of these three areas. While it’s a good idea to try to cover off all three to some extent, how much time or energy goes into each category will differ. Some companies are in a better position to give cash than time, and prefer to do this discreetly without applause. Others are aligning their branding strategies with giving and looking for maximum recognition to support their marketing efforts.

In setting priorities, it is important to define the exact causes you’ll support. We can’t help everyone, but a good plan helps a business know when to decline a request for support while knowing you’re still doing a lot to help others.

Partner country

Here are a few tips to help define the causes that will make the list:

1

Causes that matter to business owners, personally: We may have a certain passion or reason to support a community agency that has helped us.

2

Causes that matter to employees: Asking staff to recommend charities they’re involved with is a great way to connect the company’s causes with its people.

3

Causes that align with your business purpose: Giving to charities that promote trade careers for young people, for example, or supporting agencies that provide community housing may fit with your core business.

4

Causes that support your industry: Associations and other groups provide important leadership, advocacy and skill development to further your business interests.

In all cases, some quick research should be conducted into the chosen charities to provide assurance your time, treasures or talents are being put to the best use. Review financial statements, annual reports and speak with staff or board members to best understand their work and how the money is spent in the community. M e c h a n i c a l

COMPONENT A

mong the many decisions that need to be made in hydronic design are component selections. Looking around, you may encounter an overwhelming selection of parts and pieces. But which components are needed, required or optional, and why? The goal when designing or installing any heating system should be efficient, quiet, long-lasting performance that is properly sized to match the heat loss of the structure you are heating. To this end, we need a few basics on every hydronic or solar system, but there are also some addons that can make life, and servicing, much easier.

FLOW CONTROL AND ZONING

Certainly every component we discuss here adds cost and complexity to a job, and plenty of contractors are KISS-type guys and gals.

Zone valves can help manage the distribution system, but there are different schools of thought on how much zoning is required or needed. Many installers sell zoning as the

The choice to add a non-critical, yet helpful device will be between you and your customer. But also know that components make the system, and the system is a reflection of you and your expertise. Find the comfort zone with the selection and choices that suit you, and make your customer happy. Happy hydronicizing.

ultimate in comfort control, right down to a room-by-room ability to adjust temperatures for the most robust systems. Going overboard and creating micro-zones can lead to excessive boiler cycling, however, so there is a need to balance multi-zoned systems that have small zones. This is often accomplished with either a buffer tank or a large mass, high

AIR AND DIRT AND PERFORMANCE We need to have good air removal. Failure to eliminate all the big bubbles, as well as the micro air in a system, leads to numerous problems. Air causes noise, it reduces heat transfer, and with large air bubbles, you may end up with complete lack of flow. Don’t get cheap in this critical area. Micro-bubble-style air purgers do an excellent job of ridding a system of all the potential problems.

volume type of boiler. The location of air removal devices is critical. Ideally, you want them in the hottest fluid area, typically right out of the boiler, or the return side of a chiller. Expansion must be calculated and provided for if you want the system to operate as designed. Online calculators from various manufacturers can make the selection and sizing of an expansion tank quick and easy. continued on page 60

Be aware that the very wide temperature differentials experienced with solar thermal systems will impact the expansion that needs to be accommodated. Tanks will end up being unusually large to accommodate a 100 degree, or more, temperature swing of the fluids in the array. Dirt removal is another must-have. Heat exchangers in boilers are shrinking, so there is no longer any space to trap dirt and debris without affecting heat transfer. One method to catch and remove particles is the use of Y-type strainers. Dirt separators take it to another level by providing smaller particle removal and more space to trap and hold particles out of harm’s way. Media-type dirt separators will remove particles as small as five microns. I have seen the value that magnetic separation can add to a dirt separator. The magnetic function is a must, in my opinion, if you are embracing ECM technology in your pump selection.

SENSORS AND DATA LOGGING COMPONENTS With building automation becoming critical, it is advisable to start considering options to monitor systems. Many boilers now offer modules that let you monitor and data log remotely with a phone app. In some cases, adjustments can be made remotely. Contractors with jobsites scattered hundreds of miles apart are embracing Wi-Fi control and monitoring to cut down on nuisance callbacks. We may be getting close to a time when energy metering will be required. In multi-unit housing, the ability to charge the user for only the energy they use has some value, and should be of interest to the bill payers. The equipment to accurately measure and log this information already exists. In some of the European countries I have visited, the hot, cold and heating energy is metered, and d the tenants or unit owners can use a credit card to pre-purchase or add onto their energy consumption.

FINDING BALANCE Does every system benefit from having balancing valves? My thoughts are that they provide a fine-tuning mechanism for a system, so I encourage their use. Perhaps the best example of balancing value can be seen on hydronic or radiant manifolds. The valves and flow indictors allow you to make adjustments to achieve the correct flow to meet the design requirements. If you are using multiple loop lengths, for example, having a balancing function on the manifold will still allow you to get full performance, comfort and efficiency, despite having fluid travel different distances to each zone.

QUICK TIP Q Flo meters are sometimes included to Flow get a visual on flow rates and balancing adjustments. Solar thermal systems adj commonly use flow indicators. Many radiant com manifolds also provide visual flow indicators. ma

Commercial building design almost always incorporates balancing valves to fine-tune flow rates to the branches and heat emitters. Balancing contractors are often hired to dial in the system and document that it is performing to design. This holds true for domestic hot water recirculation as well. The valves allow the flow rates to multiple loops and circuits to be adjusted to prevent over pumping, noise, energy waste and potential erosion from excessive velocity. It can be worth taking some time to explore the various types of balancing valves to determine if they add value to your systems.

Find the Fix

PRIMARY/SECONDARY/MAYBE? This is a schematic of a 54-unit apartment building boiler retrofit project that you’ve been n asked to provide a quote for. After careful inspection, you know that the boilers are 1,216,000 BTUH input with an output of 973,000 BTUH, as per the boiler rating plate. The building pump has a rating plate of 135 gpm at 21’ of head. Both boilers are vented together into an exterior brick chimney that is about 60 feet high. Based on this information: 1. Is the main 4” building piping the correct size for the boilers installed? a) Yes, 4” should work just fine. b) 5” would be the correct size. c) No, it should be 3” if the delta T is 20°F. d) It is a commercial job so it will work fine if velocity is a little over four feet per second. Besides, both boilers should only be on during the coldest days of the year. 2. Are the boilers’ pumps hydraulically separated from the main building pump? a) Yes b) No

3. Is this an example of primary/secondary piping? a) Yes b) No c) Maybe? 4. This piping arrangement has been running this way for the past 40 years. Would you pipe your new boiler system this way? a) Yes, why not? It has been running this way without complaints of no heat since it was installed. b) No, it is not maximizing system efficiency. It might be running, but it certainly isn’t working!

A competent finance professional can also provide steady metrics that give you an immediate understanding of how your business is performing, and where things can improve.

2. Banks, finance companies, equipment suppliers, leasing companies and warranty companies.

Joining the Reserve There’s more to George Lloyd than being the proprietor of Lloyd HVAC Services—he’s also been in the Canadian Forces Reserve for close to 20 years. “I joined the Canadian Forces Reserve when I was 20,” he says. “I still do it now, but in a reduced role.” He got his foot in the door after his friends became reservists. “They were raving about it, so

I decided I needed to be a part of it too,” he recalls. “I’ve been doing it for a long time now, and I’ve developed good friends and relationships through it.” And he’s had some interesting experiences along the way. “I worked at the operations centre at headquarters during the Afghanistan war for a couple years. During the recession, that’s what held me over.”

Controlling His Destiny

George Lloyd W

hen life gives you lemons, make lemonade. That’s what they say, and that’s just what George Lloyd did following the 2008 recession. Lloyd studied architectural technology in college and worked a variety of jobs— including memorable stints as a welder and an assistant sheet metal worker—before getting his gasfitter licence and entering the mechanical trades. “I met some guys while I was doing a course at George Brown College and they told me about their jobs doing residential HVAC work,” he recalls. “That sounded

interesting, so I went and spoke to their boss and got a job working with them.” But when the recession hit, work became spotty, so Lloyd decided to take matters into his own hands and start his own business. “I wanted to control my own destiny,” he says. “I decided to at least try it. If it didn’t work, I still had my skills and could work for anybody.” The gamble paid off. Lloyd HVAC Services opened for business in 2011, and George Lloyd hasn’t looked back since.

OIL CHANGE TIME:

Screw Compressor Systems D

uring the life of a screw compressor, it will be necessary to change the oil.

Energize the heaters a day or two before draining the oil. Also, be sure to energize all oil heaters in the compressor and any external oil separator that may be present. Once you are ready to start draining the oil, be sure to de-energize all oil heaters. Compact screws have an integrated oil separator and oil heater. In systems where the oil separator is external to the compressor, as is the case with many semi-hermetic and open-type screw compressors, the oil heaters will be located in the oil separator.

Recharging the Oil When recharging the oil, never charge oil directly into the suction or economizer ports. Any oil injection solenoid valves will generally be closed when the compressor is not in operation, but this should be verified. Also, take care to limit the amount of exposure of air to the oil as POE oils are very hygroscopic.

Drain Points With compact screw compressors, the bulk of the oil is drained from the integrated oil separator section via the oil service valve. Oil should also be drained from the motor section. Generally, the oil filter is changed with the oil. With compact screws, however, the oil filter inside the oil separator is a lifetime filter. The only time that this filter would need to be changed is when the oil has become very contaminated. With semi-hermetic and open-drive screw compressors, the oil is drained from the external oil separator, oil cooler and oil injection lines. In order for an oil change to have the most impact, it is important to drain as much oil as possible from the system. Also, with these compressor types, there will usually be an oil filter located in the oil injection line which should be replaced.

M e c h a n i c a l

B u s i n e s s

In systems where the oil separator is external to the compressors, most of the oil can generally be charged directly into the top of the oil separator. The oil level is correct when the level is visible within the sight glass of the oil separator during operation. Keep in mind that the oil injection lines and oil cooler may have to be charged separately. As a general guideline, the total amount of oil required for recharging will be the oil separator charge, plus oil cooler charge if present, plus the charge needed for the oil injection lines. Before starting the compressor, be sure to energize heaters and allow enough warm-up time. Refer to the compressor manufacturer’s instructions to determine the minimum oil temperature requirements.

Screw compressors often use oil that has a considerably higher viscosity than the oils used in reciprocating and scroll compressors. Therefore, it is easier to warm up the containers of oil prior top charging.

70

Charge compact screw compressors so that the oil level is visible in the compressor sight glass during operation.

Conversion Corner: Q&A with Jim Thomas Question: When are HFCs, such as R-404A, R-507A, R-410A and R-134a, being phased out?

Most likely, refrigerant manufacturers will gradually replace their imports of higher GWP refrigerants, like R-404A and R-507A, with lower GWP refrigerants such as R-407F , R-442A, R-448A, R-449A and R-452A which, in most cases, can be used in the same equipment and applications.

Answer: There are currently no regulations or proposed regulations to phase out HFCs. Environment Canada is proposing a phasedown of HFCs, similar to regulations proposed by most of the other developed countries.

The proposed product controls for ACR equipment containing HFCs beginning in 2020 are as follows:

Canada is proposing controls on the import and production of all bulk HFCs, based on their total CO2 equivalent value and in addition to product-specific controls on the import and production of air conditioning and refrigeration equipment. The proposed phasedown of bulk HFCs is based on a reduction of baseline consumption, as described here:

commercial kitchens HAVE THEIR OWN STANDARDS

T

he commercial kitchen may not be the most glamorous milieu when it comes to fixtures and fittings, but whether you are dealing with a large healthcare kitchen or an individual restaurant with limited resources, getting the plumbing specs up to standard is vital to commercial operations.

Every building manager or owner/operator is aware that specifications for commercial environments can be complicated, and infractions can lead to potentially serious consequences in terms of threats to health and safety and/ or loss of revenues. “A commercial kitchen is a specially designed maze of directly connected and indirectly connected fixtures and plumbing appliances,” explains Rainier Bratsch-Blundell, a plumbing professor at George Brown College. In his presentations, Bratsch-Blundell often spends time on drainage system requirements, including grease interceptors, common and required fixtures, indirect connections and commercial dishwashers. That’s in addition to other commercial kitchen requirements, such as hand wash lavatory basins, pot sinks and pre-rinse sinks. Of course, the first “must do” is simply following the plumbing codes for your region. “Anything built in Ontario has to be by the Ontario Plumbing Code,” says Jerry Monaco, president of the Ontario Plumbing Inspectors Association and a plumbing inspector for the City of Brampton. “And you can’t put anything in unless it’s CSA approved. That means everything from the fixtures to the grease traps and interceptors.” continues on page 76

THE DISH PIT A particular area of concern for commercial kitchens is the dishwashing area, which happens to be the largest consumer of water, by far. Monaco advises operators to go top grade with everything, including the drains. “These need to be larger than required in a dishwashing area – anywhere from two- to fourinches. You don’t want anything to happen and have to spend extra money if it blocks up. It’s easier to maintain and clean a larger pipe.”

RAINIER BRATSCHBLUNDELL’S Plumbing Basics for Commercial Kitchens A STICKY BUSINESS A particular sticking point for many plumbing inspectors, because it is often not done properly, is the selection and installation of grease traps and interceptors. Grease traps have to be large enough to handle all the plumbing fixtures you have in the kitchen, says Monaco. “That means sinks, dishwashers, floor drains – anywhere grease has to go through. In a regular kitchen, traps are under the sink and not connected to floor drains. In commercial applications, traps have to be connected.” While the code says you have to have your grease trap as close as possible to the fixture, this distance can vary quite a bit. Many sites have grease traps at each fixture, but that can be expensive to maintain, Monaco says. “A lot of new installations will have a central trap outside with all the lines going to it,” he explains. “Having the trap outside the kitchen also makes it more accessible to trucks for cleaning.” “Grease interceptors are designed to slow the flow of waste water, thereby

permitting FOG – fats, cooking oils and grease – having a specific gravity of less than one to rise to the top,” explains Bratsch-Blundell. “Code requires that a fixture that discharges sewage that includes fats, oils or grease and is located in an area that food is cooked, processed or prepared must be discharged through a grease interceptor.” While the inclusion of an interceptor can appear straightforward, problems with interceptors can sometimes arise long after the original plumbing contractor has installed the unit. Bratsch-Blundell has seen problems caused by people who have repaired the drains after traps and interceptors have been installed, or when cleaning out the system. “There are different technologies available – some newer than others – but with any of them, the biggest problem is when the grease wagon comes to clean them out and they lose screws or don’t seal the gaskets properly,” he says. “When the gas and waste water aren’t sealed, they are no longer sanitary, leading to unpleasant kitchen smells.”

Handwashing Is a Vital Component Handwashing sinks are another area of a commercial kitchen plan that can lead to problems if not deployed correctly. Monaco say contractors often resist putting in multiple hand wash basins because of the costs; but a central system isn’t enough. “Hand-wash sinks have to be within so many feet of a cooking and dishwashing area. Larger commercial kitchens may have two or three hand sinks so employees always have easy access.” Also, handwashing sinks may have different temperature requirements, depending on the area they are installed in, so Monaco recommends mixing valves to regulate temperatures to meet code requirements. “In some spaces where you have to have your hands clean all the time, such as cutting areas for meat, kitchens will often have a sink with a floor pedal. Wash sinks for meat and vegetables also have to be separate to prevent contamination, including the trap for individual drainage.”

76

M e c h a n i c a l

B u s i n e s s

1 2 . 1 6

You must have separate hand wash basins,

pot sinks and food prep sinks for each processing and preparation area. “You can’t use the same sink for washing lettuce as you do for poultry.”

Unlike devices that can be directly connected

to a sanitary drainage system, any devices used for the display, storage, preparation or processing of food or drink should not be directly connected to the drainage system. Rather, the fixture drain should be indirectly connected over and into a directly connected hub drain that terminates above the flood level rim to form an air brake (at least 25 mm). This prevents contamination when there is a blockage in the sanitary system.

While hub drains do not serve as a floor

drain, they must have the same pipe size, material and venting requirements as the floor drain.

Newer ice machines require two drains to prevent backwash and contamination. Drains and fixtures will disintegrate over

time. “That’s one of the biggest problems for kitchens, whether cast iron, copper or plastic, they will decay from the volume of water usage. Typical life expectancy is 25 years for water pipes, 15 years for toilets, two years for faucets.”

All fixtures must have cleanouts in order

to provide an access point for pipe inspections. “They are clean the day they are installed, and never after that.”

Drainage piping cannot be above food preparation areas, unless it is panned. Get permits for any renovations to ensure you don’t violate sewer use bylaws. Don’t wait for a disaster. Conduct regular inspections on pipes and fixtures. Don’t forget to install flow control.

“Inspectors see a ridiculous number of installations that have forgotten to install external flow control. I’ve seen cases where you find the external flow control still in the plastic bag inside the interceptor when you open it up.”

HYDRONICS

EXPLORING

ECM Regulatory changes, environmental consciousness and a desire to save money have driven the hydronic industry to develop WYVK\J[Z^P[OL]LYNYV^PUNLULYN`LɉJPLUJPLZ in recent years. But with so many boilers HSYLHK`WYVK\JPUN(-<,LɉJPLUJPLZPU[OL mid-90s, where else is there room to grow?

W

hile boilers often get much of the attention when it comes to energy efficiency, one of the biggest energy users in a hydronic system is often one of its smallest components: the circulator pump. But the days of constant-speed pumps are giving way to new technologies, with the current drive toward electronically commutated motors (ECMs) forging the path forward in system circulation. This is expected only to increase as Canada takes interest in the changing regulatory landscape that has taken hold in Europe, and is being considered south of the border.

HOW THEY WORK Standard AC pumps rely on electrical currents to generate a rotating magnetic field in the stator of a motor, which induces another magnetic field in the rotor. The stator’s magnetic field rotates faster than the rotor’s, which results in a slip in energy. An AC motor is also limited to

start IT UP One benefit of an ECM circulator is that it generally has a higher torque rating. “Even when a system has been dormant for an entire summer and it may be a little bit gummed up, EC motors have higher starting torque,” says Steffen Werner, Wilo’s director of marketing and Western region sales. “They’re less likely to get stuck, which is sometimes a problem with small residential circulator pumps.”

certain speeds based on the physical characteristics of the stator and rotor. Not so with an ECM circulator. “ECM motors on a circulator can help in two ways,” explains Paul Dykstra, an inside sales supervisor for Grundfos Canada. “First, the rotors are permanently magnetized to create the rotor field, and


B y Gr eg Dalgetty THE WINDS OF CHANGE The drive toward ECM technology originated in Europe, where the cost of electricity is much higher and conservation is consequently top of mind. This led to the European Union’s Energy-related Products (ErP) directive, which mandates minimum efficiency requirements for any and all electronic devices based on an Energy Efficiency Index. “Motors in general consume a huge amount of energy globally,” explains Tim Main, the Canadian market development manager for Xylem’s residential HVAC business. “These could be motors on fans, conveyor belts, anywhere—not just necessarily on a pump transferring fluid.” As such, circulator pumps—just like any other device with a motor—are subject to stringent efficiency requirements in Europe. “As of now, these regulations can only be met by EC motors,” says Werner. “I think we’ll see a movement toward mandatory EC motors here as well, just based on the fact that they can achieve better energy efficiencies.” While ECM technology is widely available in Canada, it isn’t currently mandated by the federal government, but changes could soon be on the way as the United States’ Department of Energy is working on updating energy standards, a move that Canada will likely echo. “NRCan are following pretty tight, and they normally follow the same practices because most manufacturers are in the United States, so Canada will be getting the same product regardless,” Main says. Many industry experts expect to see Canada’s guidelines updated in five or six years, but people across North America have already begun adopting ECM technology.

BAS INTEGRATION FOR GREATER EFFICIENCY The fact that ECM circulators are electrically controlled makes them easier to integrate into building automation systems, and to track system performance. “You can basically read out everything that the pump gives you at data ports,” says Werner. “Anything that’s related to building automation or getting information like water temperature, flow or head—you’ll only get that out of one of these circulators.” By regulating flow based on system requirements, ECM circulators can also help reduce return temperature in a hydronic system, thus maximizing the efficiency of a boiler. “If you don’t design to try to get the lowest possible return temperature, you’ve done a boiler no favours at all,” Giberson says. “You’ve brought hotter water back than you really wanted, and therefore you’ve killed the efficiencies of that boiler.” An added benefit of reducing flowrates when required is reducing the stress on a hydronic system.

“The biggest drivers of ECM motors, to-date, have been state efficiency programs in the U.S.,” Giberson says. While a program of that nature exists in Nova Scotia, most parts of Canada are not mandated in that way. As such, he says, “We’re just trying to drive some of the benefits of ECM technology through contractor awareness.”

the stator field is created using an electronic controller or commutator to create and adjust the rotating magnetic field. “Better efficiency is first a result of the limited slip of the stator and rotor, and second, the electronics controlling the stator are typically able to adjust the speed of the motor to suit the application where the circulator is being used.” The ability of ECM motors to automatically adjust flow can add up to big energy savings, and the fact that they are inherently variable speed eliminates the need for variable frequency drives (VFDs). “Right out of the box, ECMs are typically working at half the electrical consumption of a standard AC motor,” explains Sean Giberson, Taco’s Canadian sales manager for wholesale products. “And that’s

“With constant-speed circulators, as valves are closed to limit flow the result is increased head pressure, which can create added stress to the system,” Dykstra notes. “When a circulator can adjust its speed to match the demands of a system, the system in general is under less stress because the circulator is not producing the pressure that it would at maximum speed.” Self-diagnostics and quick set-ups are another selling point for ECM circulators. “For a contractor, time is money,” Giberson says. “These things are smart. They’ve got the diagnostic ability to tell you things. For a contractor, they have the benefits of helping them get up and running more quickly and helping them troubleshoot.”

only if we’re taking that product and running it at full speed, which you’re not most of the time.”

Hydronic water treatment filling units Water is the “life-blood” of hydronic systems. Just as we strive to maintain the health of our own circulatory systems, it’s important to maintain the “health” of water and water based solutions that circulate through the hydronic systems we construct and maintain. HYDROFILL™ portable water treatment filling units remove “hard water" scale producing minerals, such as calcium and magnesium from job-site water. Salts and other soluble minerals are eliminated to prevent premature equipment malfunction including reduced efficiency or component failure due to scale formation. HYDROFILL™ is a convenient tool for installers to use job-site water to produce ideal grade demineralized water at an economical cost per gallon.

TOOL TIP

Getting Charged up on Battery Technology

W

hen it comes to research and development in power tools, there’s been as much focus on battery technology as on the tools themselves. While once ruled by nickel-cadmium (NiCad) batteries, the world of cordless tools has, for the most part, hitched its wagon to lithium-ion cells. Lithium-ion batteries offer tool makers longer run times and increased power capacity, as well as reduced weight and recharging times. But even among lithium ion batteries, there can be differences. What’s the difference between a 3.0 amp hour battery and one that’s 9.0? Well, for one, the higher the amp hour rating, the longer the run time. Of course, a nine-amp-hour battery of the same voltage will be larger in size and weight, since it needs a few more cells within it. Much like amp hours, increased voltage will generally make for a larger battery pack; however, the higher the voltage, the higher the power provided, so there’s a trade-off of size and weight for performance. Voltage and amp hours can be multiplied to find the watt-hour rating of a battery. What this means is that two batteries with matching watt-hour ratings could be configured differently to put an emphasis on either power or run time.

CHARGE IT RIGHT If you have NiCad batteries and switch to lithium, be sure to switch the charger as well. Some chargers will accommodate either technology, but do not assume. The use of an improper charger could damage the battery, or even cause a fire.
