In-shot burners deliver the fuel-air mixture into the heat exchanger cells, and a warped, rusted, or misaligned burner is a common cause of delayed ignition, rollout, and yellow flame. Replacing a failed burner restores clean, quiet, and efficient combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: In-shot furnace burner\u003c\/li\u003e\n\u003cli\u003eNominal size: 3 inch\u003c\/li\u003e\n\u003cli\u003eMaterial: Aluminized\/coated steel\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMNT045-3B and compatible models\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas (verify orifice for LP)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman B4022700\u003c\/strong\u003e is manufactured to the exact port pattern, throat diameter, and mounting geometry of the original, ensuring correct flame carryover between cells.
