Description
The York S1-029-20423-030 Natural Gas Burner Orifice features a 0.1285-inch bore corresponding to drill size 30, calibrated to meter natural gas delivery into burner assemblies. It operates by forcing gas through a precision orifice opening, regulating discharge volume based on inlet pressure and aperture size to achieve controlled combustion features. Placed in furnace burners, rooftop heating units, and HVAC systems used in gas-fired heating and combustion equipment, it shapes flame output, influences ignition behavior, and aligns fuel delivery with air mixing requirements within heating circuits to achieve stable thermal generation during burner operation sequences.
