The Goodman 22309501 is a genuine OEM flue vent pipe designed for the GMH951155DXAC 115,000 BTU 96% AFUE two-stage furnace. This internal venting component carries combustion products from the inducer/heat exchanger assembly to the exhaust outlet, maintaining the correct flow path and sealing surfaces for safe, code-compliant venting. Because it is exposed to acidic condensate and flue gases, this pipe is a common wear item on high-efficiency condensing furnaces and should be replaced if cracked, corroded, or warped.
Choosing the genuine OEM Goodman flue pipe ensures precise fit at every gasket and clamp point — critical for a sealed combustion system. Generic substitutes rarely match the molded contours, risking flue-gas leaks and failed pressure-switch operation. For a safety-critical venting component, OEM is strongly recommended.
Moderate (2/5) — Requires disconnecting existing clamps/gaskets and reseating the new pipe with proper alignment. Shut off gas and power first, and always verify a leak-free seal and correct draft after installation.
