This formed sheet-metal component channels hot flue gases from the top of the heat exchanger into the draft hood and vent connector, maintaining proper draft and directing combustion byproducts safely out of the living space. A corroded, warped, or missing transition can leak flue gas or disrupt draft, so a correct-fit replacement is essential for safe furnace operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eComponent: Flue \/ chimney transition (bottom section)\u003c\/li\u003e\n\u003cli\u003eMaterial: Coated furnace-grade sheet metal\u003c\/li\u003e\n\u003cli\u003eFunction: Routes flue gas from heat exchanger to vent\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GDH80403ANBD and compatible 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 0128F00006\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this part must seal to the heat-exchanger flange and align with the draft hood, the \u003cstrong\u003eOEM 0128F00006\u003c\/strong\u003e is strongly preferred — the stamped geometry matches the cabinet exactly.
