Each in-shot burner directs the air-fuel mixture from the manifold into a single tube of the heat exchanger, where it ignites to produce clean, stable combustion. Over years of cycling, burners can rust, clog, or distort — causing rough ignition, flame roll-out, or noisy operation. Replacing burners as a matched set restores even firing across the heat exchanger.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eSize: 3 inch\u003c\/li\u003e\n\u003cli\u003eType: In-shot (single-port) gas burner\u003c\/li\u003e\n\u003cli\u003eFunction: Delivers air-fuel mix to one heat-exchanger tube\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana VMS80603AXAA and compatible 80% furnaces\u003c\/li\u003e\n\u003cli\u003eSold as: Individual burner\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine B4022700 is dimensioned to the exact orifice spacing and heat-exchanger geometry of the furnace, so the flame lands correctly and ignition carries cleanly burner-to-burner. Generic burners can misalign the flame, causing delayed ignition or roll-out. For a combustion component, OEM is the safe choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires removing the burner assembly, transferring\/aligning burners to the manifold orifices, and verifying flame pattern on start-up. Gas work should be done by a qualified technician; shut off gas and power before servicing and leak-check all connections afterward.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058210259315,"sku":"GOODMAN-13698","price":19.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-in-shot-burner-for-vms80603axaa-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
