SPECIFICATIONS
* Gas input ratings are certified for elevations to 2000 ft. For elevations above 2000 ft, reduce ratings 4 percent for each 1000 ft above sea level. Refer to
National Fuel Gas Code Table F4 or furnace Installation Instructions. In Canada, derate the unit 10 percent for elevations 2000 ft to 4500 ft above sea level.
† Capacity and AFUE in accordance with U.S. government DOE test procedures.
‡•Airflow shown is for bottom only return-air supply with factory-supplied 1-in. washable filter(s).
• For air delivery above 1800 CFM, see Air Delivery table for other options.
• An airflow reduction of up to 7% may occur when using the factory-specified 4-5/16-inch wide, high efficiency media filter.
• For best furnace efficiency when using the 4-5/16-inch wide media filter, adjust the blower speed tap to near the mid-point of the rise range.
** Time-delay type is recommended.
