The Goodman 22309501 flue vent pipe is a genuine OEM combustion-exhaust component for the AMVC950905DXAC high-efficiency modulating gas furnace and compatible Goodman/Amana condensing models. This internal flue routes hot combustion gases from the heat exchanger and inducer assembly to the vent connection. Because it handles corrosive, moisture-laden flue products, a cracked or degraded flue pipe can cause pressure-switch faults, spillage, and unsafe operation — making an exact OEM replacement critical for safe furnace performance.
Flue components are a safety part — this is a factory Goodman/Amana pipe molded to the precise diameter, length, and gasket geometry of the original so it seals correctly against the inducer and pressure-switch tap. Generic or improvised venting risks leaks, incorrect draft pressure, and carbon-monoxide hazards. Always use the specified OEM flue component.
Moderate (3/5). Shut off gas and power, disconnect the pressure-switch tubing, remove the retaining fasteners and gaskets, and swap the pipe — reseating all gaskets and confirming pressure-switch operation on restart. Best performed by a qualified HVAC technician; verify no flue-gas spillage after installation.
Keep your AMVC950905DXAC venting safely with the genuine Goodman 22309501 flue pipe.
