The Goodman 0128F00006 Chimney Transition Bottom is a genuine OEM flue and vent component engineered for the AMH80703AXCC gas furnace and compatible Goodman/Amana 80% AFUE models. This transition piece seats at the bottom of the flue collector to direct combustion byproducts into the vent connector, maintaining proper draft and a sealed venting path.
Using the factory part ensures the flange geometry, gauge, and mounting holes line up exactly with the collector box — no cutting, drilling, or field fabrication required.
The OEM Goodman transition is stamped to factory tolerances for a leak-tight, code-compliant fit. Generic replacements may vary in flange size and metal thickness, risking flue leaks and draft problems. For a venting component, exact fit is a safety matter — we recommend the OEM part.
Easy (1 of 5). Replacement is a simple screw-out/screw-in job for a service technician. Always shut off gas and power before servicing, and verify draft after reassembly. Professional installation is recommended for any combustion-venting work.
