NOTES:
1. Minimum return-air openings at furnace, based on metal duct. If flex duct is used,
see flex duct manufacturer‘s recommendation for equivalent diameters.
2. Minimum return-air opening at furnace:
a. For 800 CFM 16-in . (406mm) round or 14

(368mm) x 12-in. (305mm) rectangle.
b. For 1200 CFM 20-in . (508mm) round or 14

-in.(591mm) rectangle.
d. For airflow requirements above 1800 CFM, see Air Delivery table in Product Data
literature for specific use of single side inlets. The use of both side inlets, a
combination of 1 side and the bottom, or the bottom only will ensure adequate
return air openings for airflow requirements above 1800 CFM at 0.5
