Each in-shot burner directs a precise gas\/air mixture into its corresponding heat-exchanger tube for clean, quiet ignition and an even blue flame. Over time burners collect rust, scale, and spider webs that cause delayed ignition, roll-out, noisy \"whoosh\" light-off, and yellow-tipping flames — replacing worn or corroded burners restores safe, efficient combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: In-shot single burner\u003c\/li\u003e\n\u003cli\u003eSize: 3 inch\u003c\/li\u003e\n\u003cli\u003eMaterial: Coated\/aluminized steel\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMS80453AXA and related 80% 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 \u003cstrong\u003egenuine OEM B4022700\u003c\/strong\u003e is manufactured to Goodman's exact venturi diameter, port pattern, and alignment tab so flame geometry matches the heat exchanger and ignition source. Generic burners can shift the flame, causing sooting or delayed ignition. Because burners are a combustion component, we recommend OEM and replacing the full set for consistent flame.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires removing the burner assembly, aligning the burner over the orifice, and verifying flame carryover and ignition after install.
