Physical data
* Gas input ratings are certified for elevations to 2000 ft. For elevations above 2000 ft, reduce ratings 4% for each 1000 ft above sea level. Refer to National Fuel Gas
Code Table F4. In Canada, derate the unit 10% 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.
