GCP74
Description :
The GCP74 gas control valve is a multifunctional gas
control which has been specially designed for use on gas fires, convertor heaters and associated gas appliances fitted with simplex or duplex burners.
Flow Control :
Rotation of a disc valve controls the max, gas output rate proportionally down to a pre selected min.
Flame Failure Device:
The GCP74 gas control is fitted with a flame failure device which prevents the flow of gas to the burner in a no flame condition.
The pilot burner, ignition electrode and thermocouple are parts of the flame failure device thus an integral parts of the safety system.
Piezo Igniter:
A piezo igniter provides automatic ignition at the pilot gas output rate setting.
Setting the Max. Capacity :
Start gas control and turn operating knob to position fully open. Set max capacity by means of max restrictor.
Setting The Min Capacity:
Turn operating knob from position fully open down to min. position (notched), set min capacity by means of min restrictor.
Attention:
another type with Governor grade B, group 2:(ONLY GCP74/86) A device that is placed at the inlet of the control valve and it’s function is to stabilize the inlet pressure by the gas fire. This device allows the use of the ODS (Oxygen Depletion System) pilot to access the gas-fired equipment..
Technical specifications :
Connections :
Capacity :
Maximum output rate at 2.5 mm W.C. Air Pressure drop: 775 lit/h air. (d=1).
Installation :
The gas control valve can be mounted in different positions.
The gas inlet can be placed in four different positions in relations to the outlet thus reducing the pipe work to a minimum.
