Each in-shot burner directs the gas\/air mixture into one tube of the heat exchanger for clean, even combustion. Rust, scale, or a distorted burner port causes rough ignition, flame rollout, sooting, or delayed light-off — replacing the affected burner(s) restores a crisp, blue, properly seated flame.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\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 (single-port) gas burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e ADSH800403AXAA furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e Sold individually — order one per heat exchanger tube being replaced\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a \u003cstrong\u003egenuine OEM Goodman\u003c\/strong\u003e burner machined to the exact port size and venturi geometry the furnace was certified with.
