Each in-shot burner directs a precisely shaped gas-and-air flame into its heat exchanger tube, and the venturi geometry is matched to the manifold pressure so the furnace burns cleanly and lights reliably across the burner rack. A rusted, clogged, or misaligned burner causes rough ignition, roll-out, or delayed flame propagation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eType: In-shot burner, 3 in. length\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas (verify orifice for LP)\u003c\/li\u003e\n\u003cli\u003eApplication: 80% AFUE multi-position gas furnace\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \/ Amana AMH80703AXCB and compatible models\u003c\/li\u003e\n\u003cli\u003eConstruction: Corrosion-resistant coated steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B4022700 reproduces the exact venturi throat and mounting slot of the original, so flame carry-over and ignition timing stay within spec. Generic burners may have slightly different port sizing that shifts the flame pattern and can lead to sooting or flame-sensor faults.
