NOTES:

1. Two additional 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) round or 14 1/2 x 19 1/2---in. (368 x 495 mm) rectangle.

c.For 1600 CFM---22---in. (559 mm) round 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 the bottom, or the bottom only will ensure adequate return air openings for airflow requirements above 1800 CFM.

*135 and 155 size furnaces require a 5 or 6---in. (127 or 152 mm) vent. Use a vent adapter between furnace and vent stack. See Installation Instructions for complete installation requirements.
