BOILER DIMENSIONS & RATINGS
Table 11.3: Series 63™ Boiler Ratings
1. Net 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. 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.

1. Net 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 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. 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.
