Each in-shot burner directs the gas\/air mixture across its manifold orifice into the heat-exchanger tube, producing the clean, stable blue flame required for efficient, safe combustion. Furnaces use one burner per heat-exchanger cell, so replace any burner that shows rust, cracking, or flame roll-out.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: In-shot (monoport) gas burner\u003c\/li\u003e\n\u003cli\u003eLength: 3 inches\u003c\/li\u003e\n\u003cli\u003eMaterial: Coated\/aluminized steel\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMT090-5B and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eSold: Individually (one burner per cell)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B4022700\u003c\/strong\u003e is dimensioned to seat precisely against the manifold orifice at the correct distance, ensuring proper primary-air entrainment and flame length. Generic burners can sit at the wrong depth, causing lifting flames, delayed ignition, or sooting. Because burner geometry directly affects combustion safety, we recommend genuine OEM burners and replacing the full set together.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy–Moderate (2\/5)\u003c\/strong\u003e — Turn off gas and power. Remove the burner assembly retaining screws, slide the old burner off its orifice, and index the new one so the flame slot faces the igniter\/sensor. Roughly 20–30 minutes. Verify flame color after restart; if you are not comfortable working near the gas manifold, hire a licensed technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058160451955,"sku":"GOODMAN-12417","price":8.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-shot-burner-for-gmt090-5b-furnace-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
