(1) Sufx “N” indicates natural gas-red, sufx “P” indicates LP gas-red, “O” indicates oil-red, “C” indicates combination natural
gas/oil-red, “D” indicates combination LP gas/oil-red.
(2) I=B=R net ratings shown are based on 1.15 piping and pickup factor for water.
Consult manufacturer for installations having unusual piping and pickup requirements, such as intermittent system operation,
extensive piping systems, etc.
(3) The I=B=R burner capacity in GPH is based on oil having a heat value of 140,000 BTU per gallon.
(4) Boiler ratings are based on 13.2% CO
2
(oil) and 10.2% CO
2
(natural gas) and +.10” water column pressure at boiler 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.
Safety Relief Valve Set Pressure: Standard - 50 PSI; Optional - 30 PSI, 80 PSI
