Each in-shot burner directs a precise gas\/air jet into one section of the heat exchanger, producing the clean, stable flame that drives efficient heat transfer. Furnaces of this platform use a bank of these burners; replace any that are rusted, cracked, or producing a yellow\/lifting flame to restore proper ignition and combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: In-shot (single-port) furnace burner\u003c\/li\u003e\n\u003cli\u003eNominal length: 3 in.\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eFits: Amana\/Goodman AMH80403AXAA and compatible 80% furnaces\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas \/ LP (per furnace orifice)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBurner geometry — venturi throat, port angle, and length — directly controls flame quality and CO output. The OEM B4022700 matches the factory air\/fuel design for this heat exchanger, so ignition carryover and flame color stay within spec. Generic burners can alter the flame envelope, cause delayed ignition (a loud \"whoomp\"), or impinge on the exchanger. For a combustion component, OEM is the responsible choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Moderate\u003c\/h3\u003e\u003cp\u003eRated \u003cstrong\u003e3\/5\u003c\/strong\u003e. Requires shutting off gas and power, removing the burner assembly\/manifold, swapping the burner into its slot, and verifying alignment with the orifice and igniter. After install, confirm smooth ignition carryover and steady blue flames; a combustion analyzer check is recommended.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057600512371,"sku":"GOODMAN-4963","price":27.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-in-shot-burner-for-amh80403axaa-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
