{
Gas input ratings are certified for elevations to 2000 ft. (610 M). For elevations above 2000 ft. (610 M), reduce ratings 2% for each 1000 ft. (305 M) above sea
level. In Canada, derate the unit 5% for elevations 2000 to 4500 ft. (610 to 1372 M) above sea level.
}
Airflow shown is for bottom only return---air supply with factory supplied 3/4---in. (19 mm) 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---in. (110 mm) wide, high efficiency media filter.
For best furnace efficiency when using the 4---5/16---in. (110 mm) wide media filter, adjust the blower speed tap to near the mid---point of the rise range.
ICS --- Isolated Combustion System.
