Enclosure

IP54,unless otherwise specified

Strainer

A strainer is incorporated in the gas valve

3.Installation warning

Take care that installer is a trained experienced service man

Turn off gas supply before starting installation.

Disconnect power supply to prevent electrical shock and/or equiment damage

Mounting position

The gas valve can be mounted plus or minus 90 degree from the vertical

Mounting location

The distance between the gas valve and the wall/ground,must be at least 30cm

Warning

The outlet of a pressure relief valve must always be connected to the open atmosphere

4.Main gas connection theaded valve

Take care that dirt can not enter the gas valve during handing

Ensure the gas flows in the same direction as the arrow on the housing of the gas valve

Use a sound taper fiting with thread according to ISO 7-1(bs21,DIN2999) or apiece of new properly reamed pipe, free from swart

Do not thread or tighten the pipe or pipe fitting too far.otherwise valve distortion and malfunction could result

Apply a moderate amount of good quality thread compound to the pipe or fitting only, leaving the two end threads bare, pife tape may be used as an alternative

In order to tighten the pipe in the valve, do not use the actuator as a lever but use a suitable operating on the wrench boss

5.Main gas connection flanged valves

Take care that dirt cannot enter the gas vavle during hangding

Ensure the gas flows in the same direction as the arrow on the housing of the gas valve

Ensure that the inlet  and outlet flanges are in line and separated from each enough to allow the valve to be mounted between them without damaging the gasket

Place gasket if necessary ,grease it slightly to keep it in place

Mount gas valve between flanges using the bolts for each flange

6.Warning

tightness test after installation

Spray all pipe connection and gaskets with a good quality gas leak detection spray

Star the application and check for bubbles. If a leak foud in a pipe connection remake the joint

A gasket leak can usually be stopped by tightening the mounting screws.Otherwise replace the gas valve

7.Caution

Switch off power supply before making electrical connections

Take care that wiring is accordance with local regulations

Use lead wire which can withstand105 degree ambient

The electrical ON/OFF operate is provided with a terminal block for electrical connections
