NOTE:
1.A filter is required for each return-air inlet. Airflow performance included 3/4-in. (19 mm) washable filter media such as contained in a factory - authorized accessory filter rack. See
accessory list. To determine airflow performance without this filter, assume an additional 0.1 in. w.c. available external static pressure.
2.Adjust the blower airflow setting as necessary for the proper air temperature rise for each installation.
3.Airflows over 1800 CFM require bottom return, two-side return, or bottom and side return. A minimum filter size of 20” x 25” (508 x 635 mm) is required.
4.For upflow applications, air entering from one side into both the side of the furnace and a return air base counts as a side and bottom return
5..The -- entry indicates unstable operating conditions
