The 0128F00006 is a genuine OEM chimney transition bottom engineered for the Goodman ADSS800804BXAB gas furnace. This vent component forms the lower connection between the furnace flue outlet and the venting system, maintaining a properly sealed, code-compliant draft path for safe combustion by-product removal. Using the correct transition piece is critical to preventing flue gas spillage and ensuring the furnace's induced-draft system operates as designed.
The genuine Goodman OEM transition is stamped and formed to the exact dimensions of the furnace flue collar, so it seats flush without gaps or field modification. Generic or fabricated alternatives frequently require shimming, extra sealant, or trimming and can compromise the draft seal. For a safety-critical venting component, we recommend the OEM part.
Moderate. Replacement requires disconnecting the vent, removing fasteners, and re-sealing the joint. Always shut off gas and power before servicing, and have combustion venting verified after any flue work. If you are not comfortable working on venting, use a licensed HVAC technician.
