The Goodman 0128F00006 Chimney Transition Bottom is a genuine OEM flue component for ACVC800603BXAB gas furnaces. This sheet-metal transition routes flue products from the furnace's induced-draft outlet into the vent/chimney connector, maintaining the correct draft path and clearances. A corroded or ill-fitting transition can leak combustion gases or disrupt draft, so an exact-fit replacement matters.
The OEM 0128F00006 is formed to the exact flange pattern, depth, and outlet diameter of this Goodman furnace, so it bolts up flush and seals cleanly. Generic transitions often require cutting or shimming, risking flue gas leakage. For venting components tied to CO safety, OEM is recommended.
Moderate (2/5) — Shut off power and gas, remove the existing transition fasteners, transfer any gaskets, and secure the new transition with the original screws. Confirm a tight, leak-free flue connection before operating.
