Notes:

Trim suffix S = Steam Boiler
Fuel suffix N = Natural Gas
I=B=R net ratings shown are based on piping and pick-up allowances which vary from 1.333 to 1.289 for steam. Consult manufacturer for installations having unusual piping and pick-up requirements, such as intermittent system operation, extensive piping systems, etc.
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.
Boiler ratings are based on 9.7% CO2 (natural gas), + .10” (inches) water column pressure at boiler flue outlet. Ratings shown above apply at altitudes up to 2,000 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 Working Pressure: Steam Boiler – 15 PSI,
