The in-shot burner delivers a precisely shaped gas flame into the heat exchanger, providing clean, even combustion and reliable ignition. Rust, scale, or a deformed venturi on an aging burner leads to delayed ignition, flame rollout, and uneven heating — replacing the burner restores proper flame characteristics and safe operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eType: In-shot (single-port) burner\u003c\/li\u003e\n\u003cli\u003eLength: 3 inches\u003c\/li\u003e\n\u003cli\u003eCompatible Model: ACVC800805CXAB (and related Goodman 80% AFUE furnaces)\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas \/ LP (with proper orifice)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine OEM burners are stamped and gauged to Goodman's exact venturi geometry, so flame shape and crossover lighting match factory spec.
