The Goodman 22309501 Flue Pipe is a genuine OEM venting component built for the AMH950704CXAD high-efficiency gas furnace. This flue pipe channels combustion exhaust gases from the inducer/heat-exchanger assembly out through the furnace's venting system. A cracked, corroded, or warped flue pipe can allow flue-gas leakage, disrupt the pressure-switch circuit, and create a serious safety hazard — making timely OEM replacement essential for safe, code-compliant operation.
The OEM 22309501 is molded to the precise diameter, angle, and mounting geometry of the AMH950704CXAD flue path, ensuring a gas-tight seal and correct draft. Aftermarket substitutes frequently differ in fit and can compromise the venting seal, leading to pressure-switch faults or unsafe flue-gas escape. Because this part is safety-critical, the genuine Goodman/Amana component is strongly recommended.
Moderate (3 of 5). Because this part is part of the combustion venting system, it requires care and, ideally, a licensed HVAC technician. Shut off gas and power, disconnect the existing flue section, inspect gaskets and clamps, and install the new pipe ensuring all seals are gas-tight. After installation, a combustion and draft check is recommended to confirm safe operation.
