The genuine Goodman 22309501 flue pipe is the OEM exhaust venting component for the Goodman GKS90704CXAC high-efficiency gas furnace and compatible GKS90 series units. It channels combustion byproducts from the inducer assembly through the furnace's venting system, ensuring safe, code-compliant exhaust of flue gases away from the heat exchanger.
This OEM flue pipe is dimensioned to Goodman's exact inducer and vent-collar connections, maintaining a proper gas-tight seal. Generic vent pipe can misfit at the collar and risk flue-gas leakage — a serious safety concern. The genuine 22309501 preserves combustion safety and warranty coverage.
Flue components affect combustion safety and should be handled carefully. Shut off gas and power, disconnect the old flue pipe at both connections, install the OEM pipe with correct sealing, and verify all joints are gas-tight. A carbon monoxide check after startup is strongly recommended — professional installation advised.
