The Goodman 0128F00006 Chimney Transition Bottom is a genuine OEM flue/vent component engineered for the ACVC80603BXCA gas furnace and compatible Goodman/Amana 80% AFUE models. This transition piece forms the lower connection between the furnace flue collar and the venting system, ensuring a tight, properly aligned path for combustion byproducts. A correctly seated transition is essential for safe draft and code-compliant venting.
This is the genuine OEM Goodman part, manufactured to the exact dimensions and gauge specified for your furnace. Generic transitions often vary in flange size and collar diameter, leading to gaps, draft issues, and time-consuming field modifications. Choosing OEM guarantees a drop-in fit and preserves your equipment warranty.
Easy (1/5). Replacement is a straightforward mechanical swap requiring basic hand tools. Always shut off gas and power before servicing, and confirm proper draft after installation. Professional installation is recommended for any combustion-venting work.
