Description
The York S1-029-25456-000 Burner Orifice 2GRV 43 is a gas metering component used in heating systems to regulate fuel delivery to the heat assembly. It controls the flow of gas through a calibrated 0.089-inch opening, supporting a consistent combustion within furnaces and related heating equipment in residential and light commercial HVAC systems. It is installed in gas burner sections where inputs are required for proper system operation. It forms part of the fuel delivery pathway, working with the manifold and burners to maintain stable heating performance and combustion balance in gas-fired equipment.
