The supply pipeline should be ofa suitable size to ensure maxunurn florv can be abhieved. It is not recommended that the oil supply to the stove be tee'd ofT frorn a line feeding another appliance e.g. a pressurejet boiler or cooker. A dedicated oil f'eed should be provided for the stove to avoid the possibility ofthe pumped appliance denying oil to the stove bumer- A 5-10 Micron filter must be fitted into the oil supply line. A manual isolating valve must be fined close to the appliance. The oil inlet to the stove requires an 8mm diarneter pipe.

{ Location I

Refer to Building Regulations l, 2 and 3. To obtain the maximum heat input into the room, it is an advantage not to install the stove into a recess. Should the stove be fitted into a recess, the minimum dimensions sho$'n in Fig. 4 should allou, optimum heat output to the room. To ensure adequate alr circulation, it is recornmended that any recess should not exceed 300 mm rn depthThe appliance must be mounted on a level hearth of solid non-combustible material. extending at least 225 mm in front ofthe stove and 150 mm beyond each side (See building regulations Section 2) The rear rvall must be of a non-combustible matenal rvith an unrestricted air gap ofat least 75 mm behind the appliance as shorvn in Ftg. 4.

tlre nnnual lighting nrethod User Advice Periodically, mainly due to varying flue draught conditrons, a slight dry soot haze may occur on the glass. To clean the glass, tum the regulator to position I and allorv the fire to subside. Open the vier.ling door with the tool provided and quickly wipe the inside ofthe glass with a clean dry cotton cloth. Under no circumstances should nylon fabric be used or any harsh abrasive. Do not use any form ofliquid cleaner or water on hot glass. Should a persistent stain remain a nylon pan scourer may be employed (dry) when the glass has cooled. Avoid wiping the stove rvith a damp cloth until after the initial firing, as this first subjection to heat is part ofthe paint curing process. Alternatively for persistent stains, use Yeoman proprietary glass cleaner, use rvhen cold only.

It is recommended that this unit be operated as a continuously run appliance dunng the heating season. lfused intennittently for long periods, more fiequent servlclng may be necessary. During the summer months or long periods of rron-use rt is recommended that the oil suonlv to the stove be tumed off. Servicing Your stove will require sen,icing at approximately 6 rnonthly rnten'als. usually at the

ofthe heating season. Servicing should only be undertakcn by trainediexperienced installers preferably OFTEC registered.
