Each in-shot burner directs the gas\/air mixture into a heat-exchanger tube where it ignites and carries the flame across the section. Over time burners corrode, distort, or clog with rust and debris, producing lazy or yellow flames, delayed ignition, roll-out, and reduced efficiency. Replacing worn burners restores crisp blue flames and reliable, complete combustion. Furnaces use one burner per heat-exchanger cell, so match the quantity to your model.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: B4022700\u003c\/li\u003e\n\u003cli\u003eType: In-shot (mono-port) burner\u003c\/li\u003e\n\u003cli\u003eNominal Size: 3 inch\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana ADV80703BXBB and compatible ADV-series furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: Delivers and ignites the gas\/air mixture at the heat exchanger inlet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman in-shot burners are dimensioned for the exact port size, venturi, and heat-exchanger inlet of this furnace, preserving the factory air\/fuel mixture and flame pattern.
