In-shot burners deliver the gas\/air mixture into each heat-exchanger tube for clean, efficient combustion. Over time burners can rust, clog, or develop poor flame patterns that lead to delayed ignition, flame rollout, or sooting — replacing the affected burner(s) restores a crisp, blue flame and reliable light-off.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: In-shot (single-port) gas burner\u003c\/li\u003e\n\u003cli\u003eLength: 3 inches\u003c\/li\u003e\n\u003cli\u003eFunction: Delivers gas\/air mix to one heat-exchanger tube\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement for GMT045-3B\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman genuine OEM part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine Goodman OEM\u003c\/strong\u003e burner matches the exact orifice alignment, venturi geometry, and flame characteristics this furnace was designed around.
