The in-shot burner delivers the fuel-air mixture into the heat exchanger tube, producing the stable blue flame your furnace needs for efficient, complete combustion. Over time, burners can rust, clog, or distort from thermal cycling, leading to delayed ignition, sooting, or nuisance flame-sensor lockouts. Replacing a worn burner restores clean, quiet, and reliable heating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e In-shot (single-port) gas burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e Natural gas \/ LP compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GMNT070-3B and related furnace platforms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part #:\u003c\/strong\u003e B4022700\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a \u003cstrong\u003egenuine Goodman OEM burner\u003c\/strong\u003e, machined to the exact port geometry and flame-spread pattern specified by the manufacturer. Generic aftermarket burners are cheaper but often vary in port diameter and depth, which can cause uneven flame, poor cross-lighting between burners, and higher CO output.
