This genuine Goodman 22309501 flue vent pipe is an OEM exact-fit replacement for the Goodman GMH950905CXAC two-stage condensing furnace. The flue pipe channels combustion byproducts from the heat exchanger through the induced-draft blower to the vent, a safety-critical path that must seal correctly to prevent flue gas leakage into the living space.
The OEM 22309501 is molded to the precise length, diameter, and gasket seat of the original assembly, guaranteeing a tight, code-compliant seal at the inducer and collector box. Generic or universal pipes often require modification and may not seal against the OEM gasket, risking dangerous flue gas escape. On a combustion component, always use OEM.
Moderate (3/5). Requires removing the inducer/collector box, replacing gaskets, and confirming a leak-free seal. Combustion venting is safety-critical — we recommend a qualified HVAC technician and a post-install draft/CO check. Shut off gas and power before servicing.
