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) re ctangle.
b. For 1200 CFM---20 ---in. (508 mm) roun d or 14 1/ 2 x 19 1/2---in. (368 x 495 mm) rectangle.
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 sideinlets,a
combination of 1 side and the bottom, or the bottom only will en sur e a dequate retur n air openings f or airflow requirements above 1800 CFM.

* 5--- in. or 6--- in. (127 or 152 mm) vent connector may be required in some cases.
{ 135 and 155 size furnaces require 5---in. (127 mm) or larger vents. Use a 4 to 5 or 4 to 6---in. (102 to 127 or 102 to 152 mm) vent adapter between furnace and
vent connector.
