Note: Maximum undiluted propane capacities listed are based on an 11-in. w.c. setting and 0.5-in. w.c. pressure drop. Capacities in 1000 Btu/hr.
Notes: 1. Maximum undiluted propane capacities listed are based on a gauge pressure of 10-psi first-stage setting and 1-psi pressure drop. Capacities in 1000 Btu/hr. 2. To convert to capacities at a gauge pressure of 5 psi setting with 10 percent (0.5 psi) pressure drop, multiply values by 0.606. To convert to capacities at a gauge pressure of 15 psi setting with 10 percent (1.5 psi) pressure drop, multiply values by 1.380. * This section is an excerpt from the NFPA 58 Liquified Petroleum Gas Code — 2001 Edition
