The Goodman 0128F00006 Chimney Transition Bottom is a genuine OEM flue-vent component for the AMH80803BXBA gas furnace and compatible Goodman/Amana models. This sheet-metal transition adapts the furnace vent outlet to the chimney/flue connector, forming the lower section of the venting path that carries combustion byproducts safely out of the heat exchanger. Proper fit here is critical to draft and to preventing flue-gas spillage into the living space.

OEM vs. Generic

The OEM 0128F00006 is formed to the exact flange dimensions and screw pattern of the AMH cabinet, so it seals to the vent collar without gaps. Field-fabricated or generic transitions risk leaks, poor draft, and code issues. OEM ensures a clean, listed venting connection.

Installation Difficulty

Moderate (2/5) — Requires sheet-metal screws and high-temp sealant at the joints, plus a draft/spillage check after installation. Shut off power and gas, and confirm proper venting before returning the unit to service.
