The Goodman 22309501 is a genuine OEM flue pipe vent section engineered as a direct-fit replacement for the GKS90453BXAE gas furnace. This component carries combustion exhaust from the inducer assembly to the venting system, and a properly sealed, correctly sized flue is essential for safe operation and correct pressure-switch response.
The OEM Goodman 22309501 is formed to the exact geometry, gasket surface, and gauge the furnace requires, which matters for a gas-tight, code-compliant exhaust path. Because the flue is a combustion-safety component, we strongly recommend the genuine OEM part over a generic substitute to preserve proper draft and pressure-switch calibration.
Moderate (3 of 5). Replacement involves shutting off gas and power, removing the existing flue fasteners and gaskets, and re-sealing all joints. Because this is a combustion-exhaust part, we recommend a qualified HVAC technician perform the swap and verify draft and CO levels after installation.
