The Goodman 0128F00006 is a genuine OEM chimney transition bottom (flue vent transition) for ADVC80805CXBB gas furnaces and compatible Goodman/Amana models. This sheet-metal adapter connects the furnace flue collector/draft hood to the vent pipe, maintaining the correct draft path so combustion byproducts vent safely out of the home. A corroded, cracked, or ill-fitting transition can cause draft problems, condensation, rust, or dangerous flue-gas spillage.
The OEM Goodman 0128F00006 is stamped to the precise dimensions and hole pattern of the furnace's vent system, ensuring a leak-free, code-compliant fit. Universal or fabricated transitions may not seal properly, risking flue-gas leakage. For venting components we recommend OEM for a guaranteed fit.
Moderate. Requires disconnecting the vent pipe, removing sheet-metal screws, swapping the transition, and re-sealing. Basic sheet-metal tools and attention to a gas-tight vent connection are needed; verify proper draft after install or use a professional.
