BOILER DIMENSIONS & RATINGS
Table 11.3: Series 63™ Boiler Ratings
1. Net I=B=R Ratings are based on DOE Heating Capacity less an allowance for normal piping and pickup as determined by
the Testing and Rating Standard for Low Pressure Cast Iron Heating Boilers of the Hydronics Institute. Water ratings are based
on a piping and pickup factor of 1.15. Steam ratings are based on a piping and pickup factor of 1.33. Consult PB Heat
before selecting a boiler for gravity hot water installations or for installations having unusual piping and pickup requirements
such as exposed piping, night set back, etc. Ratings shown are for elevations up to 2,000 feet. For elevations above 2,000
feet, ratings should be reduced at the rate of 4% for each 1,000 feet above sea level.
2. Minimum Natural Gas Inlet Pressure exceptions: 63-04 STDG 5.3"; 63-06 STDG 5.5"; 63-06 SPRK 5.3".
3. Heating Capacity and Annual Fuel Utilization Efficiency (AFUE) ratings are based on U.S. Government tests. Before
purchasing this appliance, read important information about its estimated annual energy consumption or energy efficiency
rating that is vailable from your retailer.
NOTE: Minimum Inlet Gas Pressure: Natural Gas @ 5.0 in. W.C.², LP Gas @ 11.0 in. W.C.

1. Net I=B=R Ratings are based on Gross Output less an allowance for normal piping and pickup as determined by the Testing
and Rating Standard for Low Pressure Cast Iron Heating Boilers of the Hydronics Institute. Water ratings are based on a
piping and pickup factor of 1.15. Steam ratings are based on a piping and pickup factor of 1.33. Consult PB Heat before

should be reduced at the rate of 4% for each 1,000 feet above sea level.
2. Minimum Natural Gas Inlet Pressure: 5.0 in. W.C. except for 64-08 STDG 5.3 in., 64-12 STDG 5.1 in.
3. Combustion efficiency and gross output are determined in accordance with ANSI Z21.13 / CSA 4.9, Gas-Fired Low-Pressure
Steam and Hot Water Boilers.
