Table 10.1: Boiler Ratings
Table 10.2: Combustion Air Fan Speed
1.
Net I=B=R ratings are based on an allowance of 1.15.
2.
Consult factory before selecting a boiler for installations having unusual piping and pickup requirements, such as
intermittent system operation, extensive piping systems, etc.
3.
Heating Capacity and Annual Fuel Utilization Efficiency (AFUE) ratings are based on U.S. Government Testing.
Note: These values are subject to change without notice.
