Each burner directs gas from the manifold orifice into the heat exchanger, where it mixes with primary air to produce a stable, blue flame. Over time burners can rust, clog with scale, or distort from years of thermal cycling, causing rollout, delayed ignition, or a yellow, sooty flame. Replacing the burner restores reliable, efficient heating.\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) burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet size:\u003c\/strong\u003e 3 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Coated steel for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e ACEC800805CXAA and compatible Goodman\/Amana gas furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e Natural gas (pair with matching orifice for LP conversions)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is the \u003cstrong\u003efactory OEM burner\u003c\/strong\u003e — exact port geometry and inlet dimensions guarantee correct flame shape and clearance to the flame sensor and igniter. Aftermarket generics are typically 20–30% cheaper but can vary in port size, leading to flame impingement or nuisance lockouts. For a combustion component, OEM is the safe choice.\u003c\/p\u003e\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDifficulty: Moderate.\u003c\/strong\u003e Requires shutting off gas and power, removing the burner assembly, and verifying flame alignment on restart.
