Description
The Weil McLain 560-528-950 Natural Gas Pilot Orifice is a precision metering component used to regulate fuel flow to the pilot burner assembly. It features a 0.026-inch calibrated opening that controls the small, steady gas supply required to maintain a continuous pilot flame. It is applied in gas-fired heating systems within-boiler and furnace assemblies where pilot ignition is needed for main burner operation. The orifice is installed in the pilot gas line at the burner assembly ensuring controlled fuel delivery for stable flame formation, and consistent ignition performance during heating system operation cycles.
