In-shot burners deliver the fuel-air mixture into the heat exchanger tubes for clean, efficient combustion. Over time burners corrode, clog with rust flakes, or distort from heat cycling — causing rough ignition, delayed light-off, or uneven flame. Replacing worn burners restores smooth, quiet startup and proper flame characteristics.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: B4022700\u003c\/li\u003e\n\u003cli\u003eBurner Type: In-shot, 3-inch\u003c\/li\u003e\n\u003cli\u003eCompatible Model: GMNT080-4B (80,000 BTU furnace)\u003c\/li\u003e\n\u003cli\u003eMaterial: Aluminized\/coated steel, precision-formed venturi\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B4022700\u003c\/strong\u003e is stamped to Goodman's exact venturi geometry, so the flame profile, orifice alignment, and BTU rating match the furnace's design. Generic burners often have slightly different air-intake shaping that can cause flame lift, sooting, or flame-sensor dropouts. When rebuilding a burner assembly, replace all burners as a set for even flame.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eRated 2\/5. With power and gas off, the burner slides out of its slot after removing the manifold or retaining bracket. No special tools are required beyond a nut driver. Most homeowners complete a single-burner swap in 15–20 minutes. Inspect the flame sensor and igniter while the burner box is open, and verify a crisp blue flame after reassembly.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058129944947,"sku":"GOODMAN-11691","price":8.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-shot-burner-for-gmnt080-4b-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
