The genuine Goodman 22309501 flue vent pipe is a factory replacement for the AMV90453BXBB high-efficiency gas furnace. This internal vent section channels combustion exhaust from the inducer/collector assembly to the furnace's vent outlet. Because it handles hot flue gases, an OEM-spec pipe with the correct diameter, length, and sealing surfaces is essential for safe, code-compliant venting and proper draft.
The OEM 22309501 matches the factory port geometry and gasket surfaces, ensuring a sealed connection to the inducer housing and vent collar. Generic or improvised venting risks exhaust leaks, poor draft, and safety-control lockouts — and can void warranty or fail inspection. For a safe, sealed fit, use the OEM flue pipe.
Moderate (3/5). Requires removing the existing flue section, transferring or replacing any gaskets/clamps, and verifying a sealed connection. Because this is a combustion-exhaust component, we recommend a qualified HVAC technician and a post-install draft and combustion check. Always shut off power and gas first.
