Genuine Goodman flue pipe (part number 22309501) for the AMVC950453BXAD modulating condensing furnace. This vent tube carries cooled combustion products from the collector box and induced-draft blower to the PVC venting system. Because a 95% AFUE furnace vents wet, cooled flue gas, the flue pipe must maintain an airtight, correctly-sloped path so condensate drains back rather than pooling — a cracked or mis-fit flue tube is a common cause of pressure-switch faults and hard lockouts.
The OEM 22309501 is molded to the exact geometry of the induced-draft blower outlet and cabinet routing on this furnace, so gaskets and clamps seal on the first try. Aftermarket substitutes rarely match the flange pattern and can leak flue gas or hold condensate. We strongly recommend OEM for any flue-side part — combustion venting is safety-critical.
Rated Moderate (3/5). Requires disconnecting the vent, removing clamps/screws, and re-sealing gaskets to a leak-free finish. After installation, always test for flue-gas leaks and verify proper pressure-switch operation. If you are not comfortable working around combustion venting, use a licensed HVAC technician.
