In-shot burners inject the gas-air mixture directly into the heat-exchanger tubes for clean, efficient combustion. Over time burners can rust, clog with debris, or develop flame-rollout and delayed-ignition issues — replacing worn burners restores smooth lighting and a stable 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 (mono-port) burner\u003c\/li\u003e\n\u003cli\u003eSize: 3 inch\u003c\/li\u003e\n\u003cli\u003eFunction: Fuel-air delivery into heat exchanger\u003c\/li\u003e\n\u003cli\u003eFit Type: Direct OEM replacement (order one per burner position)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBurner geometry — port size, throat length, and mounting slot — directly controls flame quality and ignition timing. The genuine Goodman B4022700 matches the furnace's manifold spacing and orifice alignment for reliable cross-lighting between burners. Generic burners can cause uneven flame, delayed ignition, and flame-sensing faults. For a complete refresh, replace all burners in the set together.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (2\/5).\u003c\/strong\u003e Shut off gas and power, remove the burner-box cover and manifold, slide out the old burners, and align the new ones over the orifices. Verify flame appearance and check for gas leaks with soapy water on completion.
