The Goodman 22309501 Flue Pipe is a genuine OEM internal venting component for the Goodman/Amana AMH950904CXAG high-efficiency condensing furnace. It channels combustion exhaust from the inducer assembly to the furnace's vent connection, forming a sealed path that keeps flue gases contained inside the cabinet. Because it handles hot, acidic combustion products, a cracked or corroded flue pipe is a safety concern that can allow leakage and trigger pressure-switch faults.
The OEM 22309501 is molded to the precise diameter, angle, and gasket geometry of your furnace's vent system, ensuring a sealed, code-compliant connection to the inducer and vent coupling. Universal pipe rarely matches these tolerances and can leak flue gas or fail to seat against the factory seals. For safe venting, use the genuine part.
Allow 30–45 minutes. Disconnect power and gas, remove the burner-area panel, release the flue pipe clamps or screws and any gaskets, then fit the new pipe with fresh sealing and reassemble. Because this is on the combustion path, inspect all seals carefully — if you are not comfortable with venting work, hire a licensed HVAC technician.
