The Goodman 0128F00006 chimney transition bottom is a factory flue-vent component designed for the ADSH800804BXAA furnace. This sheet-metal transition piece connects the furnace's flue collar to the venting system, directing combustion byproducts safely toward the chimney or vent pipe. A correctly fitted transition is essential for maintaining proper draft, preventing exhaust leakage, and ensuring the furnace vents combustion gases efficiently and safely out of the home.
The OEM Goodman 0128F00006 is stamped to the furnace's exact flue geometry, guaranteeing a leak-free, code-compliant connection. A generic transition can serve as a lower-cost repair where minor field fitting is acceptable, but for guaranteed alignment on the ADSH800804BXAA cabinet, the OEM part is recommended.
Moderate (2 of 3). Involves removing the existing flue transition, verifying seal points, and securing the replacement with sheet-metal screws. Proper sealing and draft verification are critical — combustion venting should be confirmed by a qualified technician after installation.
