The Goodman 22309501 is a genuine OEM flue pipe engineered for the GKS90904CXAF high-efficiency gas furnace and compatible Goodman/Amana condensing models. This internal vent component channels combustion exhaust from the heat exchanger to the induced-draft blower and vent connection, ensuring safe and efficient flue-gas removal.
Flue components are safety-critical. The OEM 22309501 is dimensioned and sealed to Goodman's exact specification, ensuring a gas-tight fit that prevents flue-gas leakage and carbon monoxide risk. Generic substitutes may not seal correctly or withstand condensing-furnace exhaust temperatures. Always use OEM on venting.
Moderate (3/5) — Requires proper gasket/seal reassembly and a leak check after install. Professional installation recommended for flue-side components. Shut off power and gas, and verify all seals before restarting.
