The Goodman 0128F00006 Chimney Transition Bottom is the genuine OEM flue/vent transition component for the AMH80804BNBA 80,000 BTU gas furnace and compatible Goodman and Amana models. This transition piece directs combustion byproducts from the inducer/collector assembly into the vent connector, maintaining proper draft and a sealed flue path. A cracked, corroded, or missing transition can cause draft problems, flue-gas spillage, and pressure-switch faults.
This factory-original OEM transition is stamped to the exact profile and bolt pattern of your furnace's venting assembly. Universal flue adapters exist, but sealing a mismatched transition against combustion gases is risky. OEM ensures an airtight, code-correct fit on a component that handles flue gases.
Easy to Moderate — Removes and installs with a few screws; reseal any gaskets and check for leaks. Because this part is part of the venting system, verify a proper draft after replacement. When in doubt, use a licensed HVAC professional.
