The Goodman 0128F00006 Chimney Transition Bottom is a genuine OEM venting component for AMH80604BXAA gas furnaces. This sheet-metal transition adapts the furnace's induced-draft flue outlet to the vent pipe, forming the sealed bottom collar that routes combustion gases safely into the chimney or vent connector. Replace it when the original is rusted, cracked, or no longer sealing — a compromised transition can leak flue gas and disrupt proper draft.
Venting parts must match the furnace's outlet dimensions exactly to seal and draft correctly. The OEM transition is stamped to Goodman's factory geometry, so it mates cleanly to the induced-draft assembly and vent pipe. Universal generics rarely fit these 80% cabinets precisely and risk flue-gas leakage — OEM is recommended here.
Difficulty: Moderate. Power off, detach the vent connector, remove fasteners, and swap the transition, resealing joints with high-temp foil tape or approved sealant — about 30–45 minutes. A combustion/draft check is advised after reassembly.
