Each burner directs a precisely shaped gas\/air stream into its heat-exchanger tube for consistent, quiet ignition and complete combustion. Furnaces on this platform use a burner assembly of these units, so replacing rusted, warped, or clogged burners restores even flame carryover and reliable lightoff across the bank.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e In-shot single burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3-inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel:\u003c\/strong\u003e Natural gas (per furnace configuration)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold as:\u003c\/strong\u003e Individual burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMS80704BXAA and Goodman\/Amana 80% furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine OEM Goodman\u003c\/strong\u003e B4022700 is built to the exact port size, venturi geometry, and mounting slot of your furnace's burner rack. Generic burners can misalign with the manifold orifices or alter the air-fuel mixture, causing rough ignition, delayed lightoff, or sooting. OEM ensures proper flame carryover between adjacent burners and correct positioning under the flame sensor and igniter.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (2.5\/5).\u003c\/strong\u003e Requires 30–45 minutes and basic mechanical comfort: shut off gas and power, remove the burner-compartment door and manifold, slide out the affected burner(s), and reinstall aligning each to its orifice. Because gas is involved, verify a leak-free manifold and observe the flame after startup. If you are not confident working with gas components, have a licensed HVAC technician perform the swap.\u003c\/p\u003e\u003cp\u003eGenuine Goodman combustion performance.
