The Goodman 0128F00006 Chimney Transition Bottom is a genuine OEM flue/vent component for the Amana/Goodman AMEC800804BNAB gas furnace. This transition piece connects the furnace's induced-draft/flue outlet to the vent pipe or chimney, providing a properly sized, leak-resistant path for combustion gases to exit the home. A corroded, cracked, or ill-fitting transition can allow flue-gas leakage — replacing it with the factory part maintains a safe, sealed venting system.
The genuine OEM 0128F00006 is stamped to the exact dimensions and flange pattern of this furnace's vent outlet, ensuring a tight, aligned fit. Because venting integrity is a combustion-safety matter, OEM is the safest choice. Universal transitions may require field fabrication or extra sealing and rarely match the original geometry — choose OEM for a clean, code-compliant connection.
Easy to Moderate. Requires disconnecting the existing vent section, fitting the new transition to the furnace outlet, and sealing/fastening per code. Turn off power and gas, and inspect the full vent run for corrosion during replacement. A combustion analysis or draft check afterward is recommended.
Built for the AMEC800804BNAB and related Goodman/Amana furnaces. Verify your model and part number before ordering.
