In-shot burners fire a precise jet of gas-air mixture into each heat-exchanger tube; this 3-inch burner is sized to match the GDH80403ANBB's burner rack and produces the clean, stable blue flame required for efficient, safe combustion.\u003c\/p\u003e\u003cp\u003eOver time burners can rust, clog with debris, or develop flame distortion that shows up as delayed ignition, roll-out, sooting, or a yellow flame. Replacing a damaged burner restores proper flame geometry, protects the heat exchanger, and helps the furnace hit its rated input. Burners are typically inspected and replaced as a matched set for even firing.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e In-shot gas burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B4022700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Model:\u003c\/strong\u003e GDH80403ANBB gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e Natural gas (in-shot design)\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\u003eOEM Goodman\u003c\/strong\u003e burner guarantees correct orifice alignment and flame throw for the GDH80403ANBB, which is critical for safe combustion.
