The Goodman/Amana 0128F00006 Chimney Transition Bottom is a genuine OEM flue-vent component for the AMH80805CXBD gas furnace and related Goodman and Amana models. It forms the sealed bottom transition where the furnace vent outlet meets the flue collector, routing combustion byproducts safely toward the vent connector.
Venting geometry is model-specific. The OEM transition matches the exact bolt pattern and draft dimensions of your furnace, ensuring a proper gasket seal and correct draft. Generic or fabricated substitutes risk flue-gas leakage and failed draft-safety tests.
Moderate (2/5). Requires disconnecting the vent connector and unfastening the transition, then re-sealing with high-temp gasket. Plan 30–45 minutes. Verify draft after reassembly.
