The orifice meters natural gas into each burner at the exact rate the heat exchanger is rated for, so a correctly sized #43 orifice is essential for a clean blue flame, full BTU output, and safe combustion. A worn, plugged, or incorrectly drilled orifice causes lazy yellow flames, sooting, delayed ignition, and reduced heating capacity.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B4089343\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrifice Drill Size:\u003c\/strong\u003e #43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Natural Gas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread:\u003c\/strong\u003e Standard Goodman burner spud thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Machined brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Goodman GDT090-4B and related 90k BTU furnace burner assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a factory \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e orifice machined to the exact bore and thread spec of the original.
