The Goodman 22309501 is a genuine OEM flue exhaust vent pipe engineered for the WGFM295115V5DAA high-efficiency gas furnace. This internal venting component channels combustion exhaust gases from the heat exchanger through the induced-draft blower and out to the vent system. A correctly fitted flue pipe is critical for safe combustion, proper draft, and reliable pressure-switch operation.
Because this pipe handles hot, acidic combustion byproducts, the genuine OEM part is manufactured to Goodman's exact diameter, length, and material spec to ensure sealed, code-compliant venting. Improvised or universal pipe can leak flue gases, misalign with the inducer or gaskets, and create a carbon-monoxide safety hazard. For any combustion-side component, always use the factory part.
Moderate (3/5). Requires accessing the furnace vent assembly and re-sealing gasketed connections. Shut off power and gas, remove the inducer or panel as needed, replace the flue pipe with all gaskets seated correctly, and leak-test the venting. If you are not comfortable working on combustion venting, hire a licensed HVAC technician — improper flue work poses a CO risk.
