The Goodman 22309501 is a genuine OEM flue vent pipe engineered for the WGFM195090S4CAC 95% AFUE modulating gas furnace and compatible Goodman/Amana condensing models. This internal flue/vent component carries combustion exhaust gases from the heat exchanger through the inducer to the venting system. Because it handles hot, moisture-laden flue products, using the correct OEM pipe is critical for safe draft, proper combustion, and preventing exhaust leakage inside the cabinet.
Flue components are dimensionally and thermally matched to the furnace. The OEM 22309501 aligns exactly with the inducer and collector box gaskets, preserving the certified venting path. Generic or fabricated substitutes risk leaks, poor draft, and safety code violations. Always use the OEM flue part for combustion components.
Moderate — professional recommended. Because this is a combustion/venting component, it involves removing panels and reseating gaskets. Shut off gas and power, replace the pipe, verify all seals, and confirm proper draft. Improper installation can cause exhaust leaks — have an HVAC technician verify if you are not experienced with combustion systems.
