* Gas input ratings are certified for elevations to 2000 ft. (610 M). In USA, for elevations above 2000 ft. (610 M), reduce ratings 4 percent for each 1000 ft.
(305 M) above sea level. In Canada, derate the unit 10 percent for elevations 2000 to 4500 ft. (610 to 1372 M) above sea level. Refer to National Fuel Gas
Code NFPA 54/ANSI Z223.1---2006 Table F.1 (d) or furnace Installation Instructions.
† 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. An airflow reduction of up to 7 percent may occur when using a Carrier 4-5/16 in. (110 mm) high efficiency media filter.
