In-shot burners deliver the gas\/air mixture into each heat-exchanger tube, and one burner is used per exchanger cell. Rust, scale, misalignment, or a clogged crossover port causes delayed ignition, roll-out, yellow flames, or uneven heating — signs it's time to replace the burner(s).\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e In-shot (single-port) gas burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B4022700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Length:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminized \/ coated steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e Natural gas (verify orifice for LP conversions)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e Goodman DMS80905CNA (80% single-stage furnace)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Feeds flame into heat-exchanger tube\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman in-shot burners are manufactured to the exact throat diameter, crossover-port geometry, and length that match the DMS80905CNA manifold and heat exchanger. This ensures proper flame carryover between cells and clean, quiet ignition. Generic burners can alter the air-fuel mixture, risking sooting, roll-out, or a failed flame-sensor read. For a combustion component, OEM is the safe choice — and burners should be replaced as a matched set.\u003c\/p\u003e\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDifficulty: Moderate (3\/5).\u003c\/strong\u003e Involves shutting off gas and power, removing the burner assembly\/manifold, and reseating burners on the correct orifices with proper alignment.
