The optional combustion air pipe is dependent on installation/code requirements and must be 2 or 3 diameter PVC. Line voltage wiring can enter through the right or left side of furnace. Low-voltage wiring can enter through the right or left side of furnace. Conversion kits for high-altitude natural gas operation are available. Contact your Goodman distributor or dealer for details. Installer must supply the following gas line fittings, according to which entrance is used: Left: One 90 street elbow; one 2 pipe nipple; one 90 elbow; straight pipe; one ground joint union Right: Straight pipe to reach gas valve Installations using a bottom return: Failure to unfold duct flanges will reduce airflow area by approximately 18%.
