The Goodman 22309501 is a factory-original flue pipe assembly engineered for the GMS950905DXA 95% AFUE gas furnace. This component carries combustion exhaust gases from the heat exchanger through the induced-draft venting system to the vent connection. Because it operates in a high-heat, condensing environment, using the correct OEM flue pipe is critical for safe, code-compliant exhaust routing and proper draft.
This genuine Goodman OEM flue pipe is dimensioned to mate precisely with the inducer outlet and vent coupling on the GMS series. Substituting generic pipe risks improper seals, condensate leaks, and hazardous flue-gas spillage. For any component touching combustion exhaust, OEM is strongly recommended for both safety and warranty.
Moderate (2/5). Replacement requires shutting off gas and power, removing the old flue section, and confirming airtight gasket/clamp connections. We recommend a licensed HVAC technician perform any flue work and verify draft and combustion after installation to ensure safe operation.
