The Goodman 22309501 is a genuine OEM flue pipe engineered for the GMS951155DXA 96% AFUE multi-speed gas furnace and compatible Goodman condensing models. The flue pipe carries combustion exhaust gases from the inducer/collector assembly to the furnace's vent connection. Because a condensing furnace runs at high efficiency and lower flue temperatures, the internal flue routing must fit precisely to maintain proper draft and pass combustion gases safely. A corroded, cracked, or damaged flue pipe can cause pressure-switch faults, poor venting, and unsafe combustion conditions.
The OEM 22309501 is dimensioned to Goodman's exact internal vent geometry, so gaskets and clamps seal correctly and draft is maintained per the furnace's design. Because flue components handle combustion byproducts, we strongly recommend the OEM part over generic substitutes for safety and correct fit. Improper flue components can compromise venting and trip safety controls.
Moderate (3/5). Flue work involves combustion venting and should be handled by an experienced HVAC technician. Shut off gas and power, remove the inducer/vent connections, replace the pipe with fresh gaskets, and verify a leak-free seal and proper draft. A combustion analysis after service is recommended. Confirm your model number before ordering.
