The Goodman 0128F00006 is a genuine OEM chimney transition bottom for the ADSS800804BXAA gas furnace and compatible Goodman/Amana models. This flue-vent transition piece connects the furnace's flue outlet to the vent pipe, forming the lower section of the draft path that carries combustion byproducts safely out of the equipment. A properly fitted transition is essential for correct draft and for keeping flue gases contained.
The OEM Goodman 0128F00006 is formed to match the furnace's flue collar and vent geometry exactly, so it seats tightly and maintains the engineered draft. Generic or shop-fabricated transitions often leave gaps that leak flue gas or disrupt draft, risking condensation and unsafe venting. For a component in the combustion-exhaust path, OEM fit is the safe choice.
Moderate (2/5). Shut off gas and power and let the furnace cool. Remove the old transition fasteners, position the new 0128F00006 against the flue outlet, secure with sheet-metal screws, and seal joints with high-temp furnace cement or foil tape as required. Verify proper draft and check for spillage at the draft hood after restart.
