In-shot burners direct a precise gas\/air mixture into the heat exchanger cells for clean, efficient combustion. Rust, scale, or spider\/debris blockage in a burner causes delayed ignition, roll-out, sooting, or uneven flame — replacing a damaged burner restores a crisp blue flame and safe heat exchange. Sold individually so you can replace one or the full set.\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, 3\"\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (fits Amana equivalents)\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace burner assembly\u003c\/li\u003e\n\u003cli\u003eFits Model: DMP125-52AA\u003c\/li\u003e\n\u003cli\u003eMaterial: Coated steel burner tube\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e burner matches the factory venturi and orifice geometry exactly, preserving the furnace's rated flame and efficiency.
