The Goodman 0128F00006 Chimney Transition Bottom is a genuine OEM flue-vent component for the Goodman/Amana AMH80803BXBC 80,000 BTU gas furnace. This sheet-metal transition directs combustion byproducts from the furnace vent connection into the chimney/vent piping, maintaining proper draft and a sealed venting path so exhaust gases are safely carried out of the home.
The transition must match the furnace vent outlet dimensions precisely to maintain draft and a leak-free seal. Our genuine OEM 0128F00006 is formed to Goodman's exact specification for a drop-in fit. Fabricated or generic parts risk gaps and flue-gas leakage — OEM is recommended for all venting components.
Easy (2/5). Remove the fasteners securing the old transition, fit the replacement, and reseal joints with approved high-temp materials. Always verify proper draft and check for spillage after reassembly.
