Each in-shot burner meters gas and primary air into its heat-exchanger tube to produce a clean, stable blue flame. Rust, scale, or a distorted burner port causes rollout, delayed ignition, sooting, or flame-sensing faults — replacing a damaged burner restores proper, safe combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: In-shot (single-port) gas burner\u003c\/li\u003e\n\u003cli\u003eNominal length: 3 inch\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas \/ LP furnace burner assembly\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003eFits: Goodman ADSS800403AXAB and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eOEM part number: B4022700\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B4022700 is manufactured to Goodman's exact port size, venturi, and mounting alignment so the flame characteristics match the furnace's design — critical for safe combustion and correct heat-exchanger temperatures. Generic burners can alter the air\/gas mix and flame pattern. On a combustion component, OEM is strongly recommended.
