* Gas input ratings are certified for elevations to 2000 ft. (610 M). For elevations above 2000 ft. (610 M), reduce ratings 4 percent for each 1000 ft. (305 M)
above sea level. Refer to National Fuel Gas Code NFPA 54/ANSI Z223.1---2006 Table F.1 (d) or furnace Installation Instructions. In Canada, derate the unit
10 percent for elevations 2000 to 4500 ft. (610 to 1372 M) above sea level.
† Capacity in accordance with U.S. Government DOE test procedures.
‡ Airflow shown is for bottom only return---air supply. For air delivery above 1800 CFM, see Air Delivery Table for other options. A filter is required for each
return-air supply.
