Each in-shot burner directs the gas\/air mixture into a corresponding heat-exchanger tube, producing the clean, stable blue flame required for efficient combustion. Furnaces of this size typically use several burners in a rack — replace any that are cracked, rusted, or producing an uneven flame.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: In-shot burner, single\u003c\/li\u003e\n\u003cli\u003eOEM part number: B4022700\u003c\/li\u003e\n\u003cli\u003eInlet size: 3 inch\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas (convertible per furnace kit)\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003eApplication: 80% AFUE Goodman\/Amana gas furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine B4022700 is stamped and slotted to Goodman's exact port geometry, ensuring correct flame carryover and combustion. Aftermarket burners can differ subtly in port spacing and orifice alignment, causing rough ignition, delayed lightoff, or sooting. Because burner performance directly affects safety and heat-exchanger life, OEM is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Moderate\u003c\/h3\u003e\u003cp\u003eRated \u003cstrong\u003e3 of 5\u003c\/strong\u003e. Replacing a burner requires removing the gas manifold and burner assembly, then reseating the burner over its orifice and aligning it with the flame sensor and igniter. Basic hand tools and care during reassembly are needed. Always shut off gas and power, and verify proper flame after service.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eGenuine OEM Goodman part.
