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 14
b. For 1200 CFM–20-in. round or 14
c. For 1600 CFM–22-in. round or 14
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.
