The Goodman 22309501 is a genuine OEM flue vent pipe for the GKS90453BXAC high-efficiency (90%+) gas furnace. This internal flue component channels combustion exhaust from the inducer assembly toward the vent outlet, forming part of the sealed venting path a condensing furnace depends on. Because flue integrity is a safety-critical function, using the exact OEM part ensures correct fit, proper draft, and a gas-tight, code-compliant connection.
Flue and venting parts are not the place to improvise. The 22309501 is dimensioned to seal exactly against the GKS90453BXAC inducer and vent connections. Aftermarket substitutes risk poor seals, exhaust leakage, and draft problems that can trip the pressure switch or, worse, allow flue gas escape. Always use the genuine OEM flue pipe.
Rating: Moderate (3/5). Flue work involves gasketed/sealed connections and safety verification. Shut off power and gas, remove the venting access panel, detach the old flue pipe, and install the 22309501 with proper seals. After reassembly, confirm correct draft and check for exhaust leaks. Professional HVAC installation is strongly recommended for any combustion-venting component.
