Description
The York S1-029-20422-065 Natural Gas Pilot Orifice 48 is a precision metering component used to control gas flow to the pilot burner assembly. It is designed with a 0.035-inch calibrated opening that regulates the small, continuous fuel supply required to sustain a pilot flame for ignition purposes. It is applied in HVAC systems within gas-fired heating equipment where a stable pilot source is needed to initiate main burner operation. It is installed in the pilot gas line at the burner assembly and ensures controlled delivery of fuel for a consistent flame.
