The Goodman 0128F00006 is a genuine OEM chimney transition bottom used in the flue/venting path of Goodman and Amana gas furnaces, including the AMH80604BXBB 80% AFUE furnace. This sheet-metal transition connects the furnace's flue collar to the vent pipe, channeling combustion byproducts safely out of the cabinet. A corroded, cracked, or ill-fitting transition can allow flue-gas leakage and spillage — replacing it restores a proper, sealed exhaust path and correct draft.
Vent transitions are formed to match the exact flue-collar dimensions and cabinet cutout of your furnace. Generic or hand-fabricated pieces rarely seal cleanly, risking flue-gas leaks. The OEM part guarantees a factory-tight fit and correct venting geometry.
Moderate. Power down and let the furnace cool, disconnect the vent connector, remove fasteners, and swap the transition. Re-seal all joints with approved high-temp sealant and verify proper draft/spillage with a combustion analyzer or match test after startup.
