1. Two additional 7/8--in. (22 mm) 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. (406 mm) round or 14--1/2 x 12--in. (368 x 305 mm) rectangle.
b. For 1200 CFM--20--in. (508 mm) round or 14--1/2 x 19--1/3 in. (368 x 491 mm)rectangle.
c. For 1600 CFM--22--in. (559 mm) round or 14--1/2 x 22--1/16--in. (368 x 560 mm) 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 one side and the bottom, or the bottom only
will ensure adequate return air openings for airflow requirements above 1800 CFM.
