(1) Trim Suffix: S = Steam Boiler, W = Water Boiler
Fuel Suffix: N = Natural Gas, P = LP Gas, O = Oil
(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 I=B=R 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% CO2 (oil) and 9.7% CO2 (natural gas), + .10” (inches) water column pressure at boiler
fl
ue 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.
Maximum Allowable W
orking Pressure: Steam Boiler - 15 PSI, Water Boiler - 50 PSI
Standard Safety (Relief) Valve Set Pressure: Steam Boiler - 15 PSI, Water Boiler - 30 PSI
