The Goodman 22309501 is a genuine OEM flue exhaust vent pipe engineered as a direct replacement for the AMS950453BXAB gas furnace and compatible Goodman/Amana models. This internal vent component carries combustion byproducts from the inducer assembly to the furnace's vent outlet. A corroded, cracked, or warped flue pipe can allow flue-gas leakage and pressure-switch faults, making it a critical safety and combustion component.
The genuine Goodman OEM flue pipe is manufactured to precise dimensional and material specs that withstand acidic condensate and heat cycling. Generic substitutes rarely match the exact gasket seats and mounting geometry, risking leaks and improper draft. For a combustion component, OEM fit is strongly recommended.
Moderate — plan 30-45 minutes. Requires accessing the furnace vent train, removing gaskets/clamps, and reseating the new pipe with a proper seal. Because this handles combustion gases, verify all connections are gas-tight and confirm proper draft after installation. If unsure, use a licensed HVAC technician.
