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% for each 1000 ft above sea level.
In Canada, derate the unit 5% for elevations from 2000 to 4500 ft above sea level.
‡ Airflow shown is for bottom only return-air supply. For air delivery above 1800 CFM, see Air Delivery curve for other options. A filter is required for
each return-air supply.
**
Low heat CFM when bypass humidifier switch (SW-3) on control center is used.
