In-shot burners direct the air\/gas mixture into the heat exchanger tubes, where they ignite to produce the furnace's heat. Over time burners can rust, clog with debris, or develop poor flame patterns that cause rough ignition, delayed light-off, or sooting. Replacing worn burners with this OEM unit restores crisp, even ignition and efficient combustion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003eComponent Type: In-shot gas burner\u003c\/li\u003e\n\u003cli\u003eNominal Size: 3 inch\u003c\/li\u003e\n\u003cli\u003eFits: AMEH800805CNAB and compatible Goodman-family furnaces\u003c\/li\u003e\n\u003cli\u003eApplication: Natural gas \/ LP furnace burner assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B4022700\u003c\/strong\u003e is manufactured to Goodman's exact port pattern, venturi geometry, and length, so the flame aligns correctly with the heat exchanger and ignitor\/flame sensor.
