The genuine Goodman 22309501 flue pipe is the factory venting component for the AMH951155DXAF high-efficiency gas furnace. It carries combustion exhaust from the heat exchanger and inducer assembly to the venting system, and its dimensions are matched to your furnace's induced-draft pressures. Using the correct flue pipe preserves the sealed combustion path and the pressure differential the switch relies on to prove draft.
OEM vs. Generic: Flue venting is a combustion-safety component. Generic or mismatched pipe can alter draft pressure, disturb the pressure-switch reading, or fail to seal at the gaskets — risking flue-gas spillage. The OEM 22309501 matches the original bore, length, and connection points exactly, keeping the induced-draft system within spec and the seals gas-tight.
Install difficulty: Moderate (3/5). Shut off gas and electrical power to the furnace before starting. Disconnect the old flue section, transfer or replace gaskets and clamps, and seat the 22309501 fully at both joints. Because this is a combustion-exhaust part, verify all connections are sealed and, if you are not comfortable checking draft and spillage, have a licensed HVAC technician confirm safe operation.
Vent safely with the exact OEM Goodman flue pipe for your AMH951155DXAF furnace.
