Heating Capacity and AFUE are based on DOE (Department of Energy) test procedures.
1. Input rating for sea level to 2,000 ft. above sea level. Altitudes over 2000 ft. above sea
level, reduce input rate 4% for every 1000 ft.
2. Net AHRI steam ratings shown are based on a piping and pickup allowance of 1.333.
Consult manufacturer before selecting a boiler for installations having unusual piping
and pickup requirements, such as intermittent system operation, extensive piping
systems, etc.
