In-shot burners fire directly into the heat-exchanger tubes, mixing gas and primary air for a clean, stable blue flame. Furnaces use one burner per heat-exchanger cell, so the full set should be inspected together. Rusted, clogged, or corroded burners cause delayed ignition, roll-out, yellow flame, and sooting — replacing them restores efficient, safe combustion.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 3 in. in-shot (monoport) burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Single in-shot furnace burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e Natural gas \/ LP (with correct orifice)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman WFM18070S4BXCC and compatible models\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Corrosion-resistant coated steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine Goodman OEM burner\u003c\/strong\u003e is dimensioned to align exactly with the manifold and heat-exchanger inlet, ensuring the flame targets the tube correctly.
