The orifice meters the precise volume of gas into each in-shot burner, setting the furnace's input rate and flame quality. A worn, enlarged, or incorrectly sized orifice causes over- or under-firing, sooting, and poor efficiency, so it should match the manufacturer's specification and fuel type exactly.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDrill size: #43\u003c\/li\u003e\n\u003cli\u003eType: Threaded burner orifice \/ gas spud\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas (verify size against rating plate)\u003c\/li\u003e\n\u003cli\u003eOEM part number: B4089343\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (fits Amana-branded units)\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas furnace, model ADS80453ANA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B4089343 is drilled and gauged to the exact #43 bore your furnace was certified for, guaranteeing correct BTU input.
