This sheet-metal transition connects the furnace's induced-draft outlet to the vent pipe, maintaining the correct flue geometry so combustion byproducts are drawn safely up the chimney. A crushed, rusted, or mismatched transition can disrupt draft, trip the pressure switch, or leak flue gas.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Flue \/ chimney transition bottom (vent collar)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Couples draft outlet to vent connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman ADSS800403AXAC and compatible 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Galvanized\/aluminized steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount:\u003c\/strong\u003e Screws to furnace flue outlet\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Flue transitions are dimension-critical — the collar must match the furnace outlet and vent diameter exactly to preserve proper draft. This OEM Goodman part is stamped to the factory profile, unlike generic sheet-metal fittings that may require cutting or field modification.

Remove sheet-metal screws, detach the old transition, seat the new one, and reseal joints with high-temp foil tape or approved sealant. Verify draft after installation.
