C = Combustible: If placed on combustible floor, the floor MUST be wood ONLY.
NC = Non-Combustible: A combustible floor sub-base must be used for installation on combustible flooring
Notes:
• For servicing or cleaning, a 24” front clearance is recommended.
• Unit connections (electrical, flue and drain) may necessitate greater clearances than the minimum clearances listed below.
• In all cases, accessibility clearance must take precedence over clearances from the enclosure where accessibility clearances are greater.

Notes:
• Installer must supply one or two PVC pipes: one for combustion air (optional) and one for the flue outlet (required). Vent pipe must
be either 2” or 3” in diameter, depending upon furnace input, number of elbows, length of run, and installation (1 or 2 pipes). 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 90º street elbow; one 2½” pipe nipple; one 90º 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 ap-
proximately 18%. This could result in performance and noise issues.
