Physical data
*
Capacity in accordance with U.S. Government DOE test procedures.
† Gas input ratings are certified for elevations to 2000 ft. For elevations above 2000 ft, reduce ratings 2 percent for each 1000 ft above sea level.
In Canada, derate the unit 5 percent for elevations from 2000 to 4500 ft above sea level.
‡ 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.
**
Low heat CFM when low-heat rise adjustment switch (SW1-3) on furnace control is used.
