In-shot burners direct the air\/gas mixture into the heat exchanger tubes; over time they can rust, clog with debris, or develop uneven flame carryover that causes rough ignition, delayed lightoff, or a rumbling burner. Replacing worn burners restores crisp, quiet ignition and an even blue flame across the manifold.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: In-shot single-port gas burner\u003c\/li\u003e\n\u003cli\u003eLength: 3 inch\u003c\/li\u003e\n\u003cli\u003eMaterial: Coated\/aluminized steel for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GDT070-3B and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B4022700\u003c\/li\u003e\n\u003cli\u003eSold: Individually (order one per heat exchanger tube)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBurner geometry controls flame shape and carryover between ports.
