1 Net I=B=R Ratings are based on DOE Heating Capacity or Gross Output less an allowance for normal piping and pickup as determined by the T
esting 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 us 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 available from your retailer.
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.
