Each in-shot burner mixes gas and primary air and directs a stable flame jet into its corresponding heat-exchanger tube. Over time burners corrode, clog with rust and scale, or develop uneven flame patterns that trigger flame-sensor faults, delayed ignition, and rumbling. Replacing a worn burner restores clean, quiet, efficient combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eComponent Type: In-shot (monoport) burner\u003c\/li\u003e\n\u003cli\u003eThroat \/ Insertion Size: 3 inch\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMVC800804CNAB and compatible 80% AFUE furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGoodman in-shot burners are precision-drilled and gauged for the exact gas orifice and manifold pressure of this furnace. Aftermarket burners frequently have mismatched port sizing or throat geometry, producing lazy yellow flames, sooting, and CO risk. The OEM B4022700 guarantees the correct air-fuel mixture and a factory-matched flame footprint.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Moderate\u003c\/h3\u003e\u003cp\u003eRequires removing the burner assembly. Shut off gas and power, disconnect the manifold, slide out the old burner, and align the new B4022700 over its orifice into the heat-exchanger inlet. Burners are typically replaced as a matched set for even heating. A licensed HVAC technician should verify flame quality and combustion after installation.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057851908467,"sku":"GOODMAN-7961","price":14.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-in-shot-burner-for-amvc800804cnab-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
