*
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. Refer to National Fuel Gas Code NFPA 54/ANSI Z223.1---2012 Table F.4 or furnace installation instructions.
†
Capacity in accordance with U.S. Government DOE test procedures.
‡
Airflow shown is for bottom only return-air supply for the as-shipped speed tap. 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 the factory-specified 4-5/16 in. wide, high efficiency
media filter.
** Time---delay type is recommended.
