The Goodman 22309501 is a genuine OEM flue vent pipe designed for the GMH950453BXAF 96% AFUE gas furnace and compatible Goodman/Amana high-efficiency models. This internal flue component channels combustion byproducts from the heat exchanger through the inducer assembly to the exhaust venting. A corroded, cracked, or warped flue pipe can allow flue-gas leakage, trip the pressure switch, and create a serious safety hazard — making an exact-fit OEM replacement essential.
This OEM Goodman flue pipe is molded to the precise geometry, gasket seats, and heat rating of the original. Generic substitutes rarely match the sealing surfaces, risking exhaust leaks and failed inducer draft. On a combustion component, OEM fit is a safety decision — not just a convenience.
Moderate (3 of 5). This job involves accessing the inducer/heat-exchanger area and reseating gaskets. Shut off gas and power, remove the access panel, transfer the gaskets or clamps to the new pipe, and reseat it squarely. After install, verify draft and perform a combustion/leak check. If you are not comfortable working around the combustion system, we recommend a licensed HVAC technician.
