Ensure safe, reliable venting on your Goodman ADSS800804BXAD furnace with this genuine OEM chimney transition bottom. This flue-vent component connects the furnace's induced-draft/collector outlet to the vent piping, channeling combustion byproducts up the chimney. A properly fitted transition maintains correct draft, prevents flue-gas spillage, and protects against condensation and corrosion at the vent connection.
Vent fit is a combustion-safety matter. Our OEM Goodman transition is dimensioned to seal precisely against this furnace's flue outlet, eliminating the gaps and misalignment common with universal aftermarket adapters that can leak carbon monoxide. For any component in the flue path, genuine OEM is the safe choice.
Moderate (3/5). Requires disconnecting the existing vent connection, removing fasteners and any sealant, and fitting the new transition with proper alignment and high-temp sealing. Plan for 30–45 minutes. Because improper venting can cause CO exposure, we strongly recommend a licensed HVAC technician verify draft and check for spillage after installation.
