1 Net I=B=R water ratings 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 test.
