The Goodman 22309501 Flue Pipe is a genuine OEM venting component for the Goodman GMH950453BXAA high-efficiency gas furnace. In a condensing furnace, the flue pipe carries cooled combustion gases from the induced-draft blower to the vent system. Because these gases are cool and moisture-laden, the flue pipe must resist corrosion and seal tightly to prevent flue-gas leakage into the cabinet — a critical safety and performance component.
Flue components are safety-critical and must match the furnace's exact diameter, length, and gasket interface. A generic or mismatched pipe risks poor sealing, flue-gas recirculation, and pressure-switch faults. The OEM 22309501 is built to Goodman's specification for a certified, airtight fit that preserves proper draft, combustion safety, and warranty coverage.
Moderate (3/5). Plan 30–45 minutes and treat this as a combustion-safety repair. Cut power and gas, remove the blower/vent panel, detach the old flue pipe and gaskets, and install the replacement with fresh, properly seated gaskets. After reassembly, verify the pressure switch closes and check for flue-gas leaks. If you are not experienced with combustion venting, have a licensed HVAC technician perform this repair.
Keep combustion venting safe and sealed with genuine Goodman parts. Order the OEM 22309501 flue pipe today.
