In-shot burners direct a precise gas\/air mixture into each heat-exchanger tube, producing the clean, stable blue flame that drives efficient heat transfer. Rust, scale, spider-web blockage, or a corroded burner can cause delayed ignition, roll-out, sooting, or an uneven yellow flame. Replacing a damaged burner restores proper combustion and safe furnace operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: In-shot (monoport) gas burner\u003c\/li\u003e\n\u003cli\u003eLength\/size: 3 inch\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas (verify orifice for LP conversion)\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003eSold: Individually — match burner count to your model\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMS80904BNA and related 80% furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part #: B4022700\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B4022700 is dimensioned to seat correctly on the manifold and align the flame into the heat-exchanger inlet, protecting the exchanger from flame impingement.
