In-shot burners deliver the air-fuel mixture into each heat-exchanger tube, and their condition directly affects ignition reliability, flame quality, and combustion efficiency. Rust, scale, or a warped venturi causes rough ignition, delayed light-off, and short cycling — all corrected by installing fresh OEM burners.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e B4022700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e In-shot gas burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e AMS81155CXAA (multi-position gas furnace)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Corrosion-resistant coated steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM Goodman burners are stamped and tuned to the exact venturi and port pattern the furnace was certified with, preserving the factory air-fuel calibration.
