The Goodman 22309501 is a genuine OEM flue exhaust pipe for the AMV90905DXAB 90%+ efficiency gas furnace and compatible Goodman/Amana condensing models. It carries combustion exhaust gases from the inducer/blower assembly to the furnace's vent connection. On a condensing furnace this internal flue path sees hot, moisture-laden exhaust, so an exact-fit OEM pipe with the correct diameter and seal is critical for safe, code-compliant venting.
OEM vs. Generic: The 22309501 matches the precise length, diameter, and gasket geometry of your furnace's flue path. Generic substitutes risk poor seals and exhaust leaks — a safety hazard involving flue gases. OEM guarantees a proper airtight fit, correct clearances, and warranty compliance.
Install Difficulty: Moderate (2/5). Shut off gas and power, remove the inducer/vent access panel, detach the old flue pipe, and install the replacement with its gaskets fully seated. Verify all seals and check for exhaust leaks before returning to service. Roughly 30–45 minutes; basic hand tools required. Always confirm proper venting per local code.
