The orifice (or spud) threads into the manifold and meters the exact flow of gas to each burner, setting the furnace's BTU input. Using the correct drill-size orifice is essential for a clean, efficient flame and safe combustion—an incorrect orifice can cause sooting, overheating, or under-firing.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B2589345\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Burner Orifice \/ Gas Spud\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Size:\u003c\/strong\u003e #45\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Model:\u003c\/strong\u003e GSM060-3 gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine Goodman B2589345\u003c\/strong\u003e is precision-drilled to Goodman's specification for the GSM060-3, ensuring the rated gas input at the correct manifold pressure.
