The in-shot design meters natural gas through the burner throat and delivers it to the heat exchanger cell for clean, efficient combustion. Over time, rust, scale, or a distorted flame port can cause rough ignition, delayed light-off, or uneven burner flames — replacing the affected burner restores a crisp, uniform blue flame across the manifold.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eType: In-shot \/ single-port gas burner\u003c\/li\u003e\n\u003cli\u003eNominal length: 3 inches\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas (as configured on AMS80704BNA)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMS80704BNA and compatible 80% furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine OEM burner\u003c\/strong\u003e is stamped and formed to Goodman's exact port geometry, ensuring the flame carryover and heat-exchanger alignment the furnace was certified with.
