(1) Type of Build Prefix: K = Knockdown, A = Knockdown w/Assembled Sections, P = Packaged, F = Packaged and Firetested
Trim Suffix: S = Steam Boiler, W = Water Boiler
Fuel Suffix: N = Natural Gas, P = LP Gas, O = Oil, C = Natural Gas/Oil, D = LP Gas/Oil, M - Less Burner
Burner Suffix: B = Beckett, C = Carlin, J = Power Flame JR, P = Power Flame C, W = Webster, L = Less Burner
(2) I=B=R net ratings shown are based on piping and pick-up allowances which vary from 1.333 to 1.289 for steam and 1.15 for water. Consult manufacturer for
installations having unusual piping and pick-up requirements, such as intermittent system operation, extensive piping systems, etc. The burner capacity in
GPH is based on oil having a heat value of 140,000 BTU per gallon.
(3) Firebox volume does not include added volume of 8” extended burner mounting plate (BMP). If 8” BMP is specified (refer to Figure 1), add 0.7 cu. ft. to volume
listed above.
(4) Boiler ratings are based on 12.5% CO
2
(oil) and 9.7% CO
2
(natural gas), + .10” (inches) water column pressure at boiler flue outlet. Ratings shown above apply at
altitudes up to 1000 feet on oil and 2000 feet on gas.
For altitudes above those indicated, the ratings should be reduced at the rate of 4% for each 1000 feet above sea level.
Safety (Relief) Valve Set Pressure: USA Steam Boiler - 15 PSI, USA Water Boiler - 50 PSI
Optional USA Water Boiler - 30 PSI, 80 PSI (special order)
Canadian Steam Boiler - 15 PSI, Canadian Water Boiler - 45 PSI
Optional Canadian Water Boiler - 30 PSI (special order)
