In-shot burners deliver a precise, high-velocity fuel\/air stream into each heat-exchanger tube for clean, efficient combustion. Over years of cycling, burners collect rust flakes and scale that distort the flame and cause delayed ignition, roll-out, or a lazy yellow burn — replacing worn burners restores a crisp blue flame and reliable light-off.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e In-shot (single-port) burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B4022700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminized\/coated steel for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (fits Amana-branded units)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Fit:\u003c\/strong\u003e AMS81155CNA gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment Type:\u003c\/strong\u003e Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eFlame characteristics depend on exact orifice alignment and burner-throat geometry.

Generic burners can misalign with the orifice, causing rough ignition and elevated CO. For combustion components, OEM is strongly recommended.
