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

d. For airflow requirements above 1800 CFM, see Air Delivery table in
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.
