Each in-shot burner directs the air-gas mixture into a single heat-exchanger tube, producing the clean, stable flame the furnace needs for efficient, quiet combustion. Corroded, rusted, or misaligned burners cause rough ignition, flame rollout, and poor efficiency — making periodic replacement of the burner set good maintenance practice.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 3 inch in-shot burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Single in-shot \/ monoport gas burner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Delivers air-gas mixture to one heat-exchanger tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana GDT090-4B and related furnace models\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold as:\u003c\/strong\u003e Individual burner (order one per heat-exchanger tube)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Genuine Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B4022700\u003c\/strong\u003e is stamped to Goodman's exact port size and venturi geometry, so the burner seats correctly on the manifold and lines up with the igniter and flame sensor. Generic burners can differ slightly in throat diameter and orifice alignment, leading to flame lift, delayed ignition, or sooting. For proper combustion and to keep all burners matched, we recommend genuine OEM — and replacing the full set together.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Around 20–30 minutes for a full set. Shut off power and gas, remove the burner-assembly bracket, slide the old burners off the manifold orifices, and install the new ones in the same position and spacing. Reassemble, restore gas and power, and verify smooth ignition and a clean blue flame across all burners. If you observe yellow flames or rollout, shut down and call a licensed technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057146872179,"sku":"GOODMAN-B4022700","price":8.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-3-in-shot-burner-for-gdt090-4b-b4022700","provider":"National HVAC Parts","version":"1.0","type":"link"}
