In-shot burners direct the air-gas mixture into each heat-exchanger tube, producing the clean, stable flame the furnace needs for efficient, reliable heating. Rust, scale, spider-web blockage, or a distorted burner port causes rough ignition, delayed light-off, sooting, and flame-rollout faults — replacing worn burners restores crisp ignition and full heat output.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eType: In-shot gas burner\u003c\/li\u003e\n\u003cli\u003eSize: 3 inch\u003c\/li\u003e\n\u003cli\u003eFunction: Delivers air-gas mixture to the heat exchanger\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana ADVC81005CXBA\u003c\/li\u003e\n\u003cli\u003eGenuine OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBurner geometry directly affects flame shape, ignition timing, and combustion safety. The \u003cstrong\u003eOEM B4022700\u003c\/strong\u003e matches the factory port pattern, throat diameter, and mounting so the burner lights and cross-lights correctly across the manifold. Generic burners can differ enough to cause uneven flame carryover or delayed ignition. For a combustion component, we strongly recommend OEM.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Expect 30–60 minutes, and replace the full burner set if others show wear. Shut off gas and power first. Remove the burner assembly, transfer or replace burners keeping orientation consistent, verify manifold and orifice alignment, then check flame and cross-light on startup. Combustion work is best performed by a licensed HVAC technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057132454259,"sku":"GOODMAN-B4022700","price":22.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-shot-burner-for-advc81005cxba-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
