In-shot burners deliver a precisely shaped gas-air flame into each heat-exchanger tube, and this factory burner is dimpled and sized to produce clean, quiet ignition and complete combustion. Replacing corroded, rusted, or misaligned burners restores proper flame carryover, eliminates delayed ignition \"whoomp,\" and helps prevent sooting and premature heat-exchanger wear. Furnaces use one burner per heat-exchanger cell, so order the quantity that matches your unit's cell count.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: B4022700\u003c\/li\u003e\n\u003cli\u003eNominal size: 3 inch\u003c\/li\u003e\n\u003cli\u003eType: In-shot gas burner\u003c\/li\u003e\n\u003cli\u003eFits furnace model: ADSH800603AXAA\u003c\/li\u003e\n\u003cli\u003eFunction: Directs shaped flame into heat-exchanger tube\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBurners are combustion-critical, so an \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e unit is strongly preferred. It matches the factory port geometry, spud\/orifice alignment, and flame pattern your furnace was certified with. Generic burners can change the flame shape, causing flame-rollout, sensing faults, or incomplete combustion. Safety here outweighs any small savings.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3 of 5).\u003c\/strong\u003e Shut off gas and power, remove the burner assembly bracket, slide out the old burner, and align the new one over the correct orifice with proper spacing to the igniter\/flame sensor. Budget 30–45 minutes. Because this is a combustion component, verify flame quality and manifold pressure after installation — if you are not experienced with gas furnaces, use a licensed HVAC technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057501061491,"sku":"GOODMAN-3179","price":18.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-in-shot-burner-for-adsh800603axaa-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
