* As an ENERGY STAR® Partner, PB Heat has determined that these firing rates meet the ENERGY STAR guidelines for energy efficiency.
† All chimneys are 8" x 8" x 20' except those models denoted with (✝), which are 8" x 12" x 20'.
1 Burner input based on No. 2 fuel oil with a heating value of 140,000 Btu per gallon.
2 Net I=B=R water ratings based on an allowance of 1.15.
3 Net I=B=R steam ratings based on an allowance of 1.333.
4 Consult factory before selecting a boiler for installations having unusual piping and pickup requirements, such as intermittent system operation, extensive piping systems, etc.
5 Heating Capacity and Annual Fuel Utilization Efficiency (AFUE) ratings are based on U.S. Government tests, with 13% CO² and –0.02” w.c.
draft over fire. Before purchasing this appliance, read important information about its estimated annual energy consumption or energy efficiency rating that is available from
your retailer.
6 Combustion efficiency and gross output are determined in accordance with The Hydronics Institute’s Testing and rating standard for Heating Boilers; @ 12.5% CO² and -0.02”
w.c. draft over fire.
