FILTER ARRANGEMENT External filter rack required
* Gas input ratings are certified for elevations to 2000 ft. (610 M). For elevations above 2000 f t (610 M), reduce ratings 4 percent for each 1000 ft (305 M)
above sea level. In Canada, derate the unit 10 percent for el e va tions 2000 ft (610 M) to 4500 ft (1372 M) above sea level. Refer to National Fuel Gas Code
NFPA 54/ANSI Z223.1---2012 Table F.1 ( d) or fur nace 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 C FM, see Air Del ivery table f or 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. (110 mm) wide, high
efficiency media filter.
** Time-delay type is recommended.
