NOTES:
1. Two a ddi tional 7/8---in. (22 mm) diameter holes 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.
(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) roun d or 14 1/2 x 19 1/2---in. (368 x 495 mm) r ectangle.
(c.)For 1600 CFM---22---in. (559 mm) roun d or 14 1/2 x 22 1/16---in. (368 x 560mm) 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 th e bottom, or the bottom only will ensure adequate return air openings f or airflow requirements above 1800 CFM.
