Each cell of the burner assembly draws in gas from the manifold orifice and mixes it with primary air to deliver a stable, blue flame across the heat exchanger. Rusted, warped, or clogged burners cause delayed ignition, roll-out, and poor heating performance.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: In-shot (monoport) burner\u003c\/li\u003e\n\u003cli\u003eSize: 3 inch\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eFits: AMH81405DNAC and compatible Goodman\/Amana 80% furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B4022700\u003c\/strong\u003e is stamped to precise venturi and port dimensions that match the furnace's manifold pressure and orifice sizing, ensuring correct air\/gas mixing and safe flame characteristics.
