Description
The York S1-02920423042 Natural Gas Burner Orifice is a small metering component used to regulate the flow of natural gas into the burner assembly. The 0.0935 opening size defines the precise fuel passage that controls how much gas is released for proper air-fuel mixing, while the 42 sizing corresponds to a calibrated flow standard used for consistent burner output. Within HVAC systems, it is installed in gas furnace or packaged heating equipment where controlled combustion is required for steady heat generation. It is fitted directly into the burner manifold, supporting even flame distribution during heating operation.
