Each in-shot burner meters and directs the gas\/air mixture into its heat-exchanger tube for clean, quiet ignition and even flame carry-over across the burner bank. Over time in-shot burners rust, clog with scale, or develop distorted ports that cause rough ignition, flame roll-out, delayed light-off, and sooting. Replacing a worn burner restores crisp ignition and safe, efficient combustion.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B4022700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e In-shot gas burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e Goodman GMV80704BXBA (GMV80 series in-shot burner assembly)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Coated steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e 80% AFUE gas furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBurner geometry directly controls flame quality and safety. The OEM B4022700 is built to Goodman's exact port pattern and throat dimensions, so ignition and flame carry-over match the furnace's gas valve and orifice sizing. Generic burners can shift the flame profile and trigger flame-sensor or roll-out faults. For a combustion component, factory-spec is the right call — and for a matched burner bank, replace all burners together.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires removing the burner box, transferring or replacing burners while keeping them aligned to the manifold orifices, and verifying flame after restart.
