The Goodman 0128F00006 Chimney Transition Bottom is a genuine OEM flue/vent component for the Goodman/Amana ADVC81005CXBA gas furnace. This transition piece adapts the furnace vent outlet to the chimney or vent connector, channeling combustion byproducts safely out of the appliance. A properly fitted transition is essential for correct draft, condensate management, and code-compliant venting.
The OEM transition is stamped to the exact outlet dimensions and gasket points of your furnace, ensuring a leak-free flue path. Generic or fabricated adapters risk poor sealing, flue-gas spillage, and drafting problems that compromise safety. Choose factory-original for correct fit and reliable venting.
Moderate (3/5). Requires shutting down the furnace, removing existing vent fasteners, and resealing the transition to the flue collar and vent connector with appropriate high-temperature sealant or gaskets. Always confirm proper draft and check for flue-gas spillage with the furnace running after installation. Recommended for HVAC professionals.
Fits Goodman and Amana ADVC81005CXBA furnaces. Verify your model and vent configuration before ordering.
