The Goodman 22309501 is a genuine OEM flue vent pipe designed for the AMS950904CXA high-efficiency gas furnace. It channels combustion exhaust gases from the inducer/heat exchanger to the venting system with the correct diameter, length, and seal geometry required for safe, code-compliant operation of a 90%+ AFUE condensing furnace.
Because this component carries combustion byproducts, exact fit is a safety matter. The OEM 22309501 matches the AMS950904CXA's port size and gasket surface for a sealed connection. Generic substitutes may not seal properly, risking flue-gas leakage or improper pressure-switch operation. Always use factory venting components.
Moderate (3/5). Requires shutting off gas and power, disconnecting the existing flue section, and verifying an airtight reseal. Because it involves combustion venting, professional installation and a post-repair combustion/CO check are strongly recommended.
