NOTE:
1. A filter is required for each return ---air inlet. Airflow performance includes a 3/4 ---in. (19 mm) washable filter media such as contained in a factory ---author-
ized 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 SPEED TAPS AS NECESSARY FOR THE PROPER AIR TEMPERATURE RISE FOR EACH INSTALLATION.
3. Shaded areas indicate that this airflow range is BELOW THE RANGE ALLOWED FOR HEATING OPERATION.
4. 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.
5. 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.
6. All airflows that are shown in BOLD exceed 0.58 watts per CFM at the given external static pressure.
