NOTES: 1. Two additional 7/8-in. dia. knockouts are located in the top plate.
2. Minimum return-air openings at furnace, based on metal duct. If flex duct is used, see flex duct manufacturer’s
recommendations for equivalent diameters.
3. Minimum return-air opening at furnace.
a. For 800 CFM-16-in. round or 14-1/2 x 12-in. rectangle.
b. For 1200 CFM-20-in. round or 14-1/2 x 19-1/3 in. rectangle.
c. For 1600 CFM-22-in. round or 14-1/2 x 22-1/16-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 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.
