In-shot burners inject the gas\/air mixture directly into each heat-exchanger tube; a warped, rusted, or clogged burner causes rough ignition, delayed light-off, yellow flame, and sooting. Furnaces use one burner per heat-exchanger cell, so replacing the full set at once restores even, quiet ignition across all tubes.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: B4022700\u003c\/li\u003e\n\u003cli\u003eType: In-shot (single-port) gas burner\u003c\/li\u003e\n\u003cli\u003eLength: 3 inches\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GDH80403AXBD and compatible 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eSold individually — order one per heat-exchanger tube\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman burners are stamped to the precise venturi and flame-slot geometry the furnace was certified with, so the flame carries correctly to the flame sensor and igniter.
