This sheet-metal flue-venting component forms the lower transition between the furnace's induced-draft blower outlet and the chimney\/vent connector, directing combustion byproducts safely into the venting system. A properly fitted transition maintains draft, prevents flue-gas spillage, and keeps the venting path sealed and code-compliant.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Chimney\/flue vent transition (bottom section)\u003c\/li\u003e\n\u003cli\u003eFunction: Draft-blower-to-vent flue connection\u003c\/li\u003e\n\u003cli\u003eOEM part number: 0128F00006\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana (interchangeable)\u003c\/li\u003e\n\u003cli\u003eMaterial: Formed galvanized steel\u003c\/li\u003e\n\u003cli\u003ePrimary fit: AMH80403ANBA and related AMH8 furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eFlue transitions are cut and formed to match the specific outlet dimensions and gasket surfaces of the furnace's draft assembly. The genuine OEM 0128F00006 aligns exactly, so the joint seals cleanly and the induced-draft pressure switch reads correctly. Universal or shop-fabricated substitutes often leak at the seams or distort the venting path, risking flue-gas spillage and pressure-switch faults.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires accessing the draft assembly, transferring gaskets\/hardware, and verifying a leak-free, properly sealed vent connection. Shut off gas and power before servicing. After installation, confirm correct draft and pressure-switch operation.
