NOTES: 1. Minimum return-air openings at furnace, based on metal duct. If flex duct is used, see flex duct manufacturer’s recommendations for equivalent diameters.

2. Minimum return-air opening at furnace:

a. For 800 CFM–16-in. round or 141/2 x 12-in. rectangle.

b. For 1200 CFM–20-in. round or 141/2 x 191/2-in. rectangle. c. For 1600 CFM–22-in. round or 141/2 x 231/4-in. 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” W.C. ESP.
