The Goodman 0128F00006 is a genuine OEM chimney transition bottom for the AMEH800805DNAA gas furnace and compatible Goodman/Amana models. This flue/vent component forms the sealed connection between the furnace collector box and the venting system, directing combustion byproducts safely up the chimney. A corroded, warped, or missing transition can cause flue-gas leakage, poor draft, and dangerous spillage of carbon monoxide into the home.
Venting components must fit the exact port geometry to seal correctly. A universal or generic transition may leave gaps that allow flue-gas spillage. This OEM Goodman transition matches the original dimensions precisely, maintaining a proper, gas-tight venting path.
Moderate. Requires removing the vent connection, cleaning mating surfaces, fitting the new transition, and re-sealing with high-temp materials per code. Because it handles combustion gases, a draft and spillage test after installation is essential. Estimated time: 30–45 minutes.
Combustion venting is safety-critical. Verify proper draft after installation. If unsure, consult a licensed HVAC professional.
