Safety Instructions

Definition of symbols

This symbol indicates cautionary information. The statements WARNING, ATTENTION, CAUTION

indicate a potentially hazardous situation with the risk of property damage, injuries or death.

WARNING: Carefully read and follow all instructions in this sheet and all instructions on the

appliance. This unit must be installed by authorised service personnel in accordance with the

regulations in force. Incorrect installation, adjustment, modification, operation or maintenance may

cause fire, explosions, property damage, and injuries or death. All repairs, adjustments and servicing

must be made in conjunction with the gas appliance and in accordance with the appliance

manufacturer’s instructions.

Keep operating instructions in a safe place.

CAUTION: It is possible to use fluids other than stated in the chapter Specifications but, this must first

be confirmed by the manufacturer.

In places where it is necessary to withstand high temperatures, the gas valves must be preceded for

instance, by a thermally activated shutting-off device for gas. It may be necessary to discuss these measures

with the manufacturer.

Storage and transport temperature -20°C to 65°C, dry and free of dirt. Protect the valve from adverse

weather conditions e.g. rain, splash water (otherwise use drying agent).

•

Protect against external forces (shock, Vibration etc.). Do not damage the surface

Ensure that valve body and piping are free of impurities, see also chapter Troubleshooting.

Ensure installation without tension and torque.

Do not use the valve as a step or fixation point. Only piping supports it.

Protect valve from dust or dirt on construction sites. Provide strainer or filter upstream of valve.

Use compensators to balance thermal expansion of piping.

Installation

WARNING: Explosion hazard. To prevent leakage of upstream gas, shut off the gas supply at the

main manual shutoff valve before installing or servicing the GH-5000 valve.

CAUTION: Equipment damage. To prevent damage to the valve when mounting to pipework, do not

use a wrench on any surface other than the casting flats provided at the inlet and outlet ends of the valve

body.

IMPORTANT: Ensure that the drilled holes in the actuator cover are not covered. These holes are

necessary for ventilation and must not be covered by paint or other materials.

Perform the following procedure to install the GH-5000 valve.

• Ensure that the specified maximum ambient temperature is not exceeded (see Table 1).

• Ensure that the power supply voltage is compatible with the required control valve voltage.

• Ensure the gas flows through the valve body in the direction indicated by the arrow on the valve body.

Leakage can occur if the valve is installed with the gas flow in the opposite direction of the arrow.

IMPORTANT: Do not install the actuator upside down. Install vertically wherever possible.

• The GH-5000 valve contains hydraulic fluid that the pump needs to operate the valve. Therefore, the

valve may be mounted horizontally with the actuator pointed up (vertical) or in one plane in positions that

do not exceed 90° from vertical. See Figure 1 and the valve position label.

• The valve may also be mounted vertically in any position around its axis, provided that the actuator is

mounted to the valve within the range indicated on the valve label. To provide application flexibility in

mounting, the actuator of the valve may be removed and rotated. However, the mounting of the valve

must still be within the range indicated on the valve label.

90° Maximum

from Vertical

Limited Horizontal and Vertical

IMPORTANT: Refer to valve

label for mounting

positions.

Figure 1: Mounting position

• If installing a valve with threaded connections, use an approved pipe joint sealing compound on male

threads before assembly. An optional thread lubricant may have been factory applied to the first

two or three threads of the inlet and outlet to avoid galling. Ensure that excess compound is removed.

Threads of pipe and nipples must be smooth and free of tears and burrs. Steam clean all piping to

remove foreign substances such as cutting oil or thread chips.

• If installing a valve with flanged connections, ensure that all mating surfaces are free from burrs and

loose particles. Ensure that gaskets and O-ring seats are correctly positioned in mating flanges. Ensure

that approved jointing compounds are not excessively applied.

• Check for leakage before making any valve adjustments. Close the upstream shutoff cock. Connect air

tubing with a maximum of 70 mbar(1 psi) pressure to the inlet pressure connection. Paint the pipe

connection to the valve with a rich soap and water solution (or use acceptable gas leak detection

equipment). Open the upstream shutoff cock. If bubbles occur, this is an indication of a gas leak. To stop

a leak, tighten joints and pipe connections. Replace the part if the leak cannot be stopped.

• Make wiring connections. Refer to the Wiring section for specific wiring instructions.

Wiring

WARNING: Shock hazard. Disconnect the power supply before making electrical connections to avoid

electrical shock or equipment damage. Ensure that the operating voltage is identical to the information on the

product identification label.

Make wiring connections in accordance with Table 1.

Table 1: Electrical connections

With the gas line closed, apply power to the actuator and move the valve at least three times through the complete

stroke range to ensure faultless operation.

Checkout Procedure

WARNING: Fire or explosion hazard. Avoid personal injury or property damage by ensuring that the valve

functions properly and there are no gas leaks. Follow this checkout procedure before leaving the installation.

• Close the upstream shutoff cock and connect air tubing with a maximum of 1 psi (70 mbar) pressure to the

inlet pressure connection.

• Paint the pipe connections of the valve with a rich soap and water solution (or use acceptable gas leak

detection equipment) to check for leakage. Open the upstream shutoff cock. If bubbles occur, this is an

indication of a gas leak. To stop a leak, tighten joints and pipe connections. Replace the part if the leak cannot

be stopped.

• Refer to the Adjustments section to make any necessary valve setting adjustments.

WARNING: Fire or explosion hazard. Valve settings must be in accordance with the manufacturer’s

specifications.

• Before leaving the installation, observe at least three complete operating cycles to ensure that all components

are functioning correctly.

Adjustments

WARNING: All repairs, adjustments and servicing must be made in conjunction with the gas

appliance and in accordance with the appliance manufacturer’s instructions. Only authorized

personnel should make adjustments in accordance with the regulations in force.

WARNING: Explosion hazard. The minimum flow rate of the valve must not be adjusted below the

minimum safe working rate of the appliance.

The GH-5000 valve can be adjusted through the use of three adjustable switches located inside the terminal

box of the actuator. The screws of these switches adjust the stroke, which affect the flow rate, depending on

the version of the actuator. (See Figure 2). Loosen the four screws of the terminal box cover and remove it to

access the adjustable switches.

Do not adjust the switches S and R below 3 mm stroke to obtain safe working of the appliance.

Do not make any adjustments on the sealed grub screw (M)!

Do not make any adjustments on the sealed screw (MR)!

Switch M

The valve is factory set to full flow. To adjust the maximum flow rate, turn the ‘M’ (Maximum Flow) screw.

Turn the screw clockwise to reduce and counterclockwise to increase the flow rate.

Switch S

For CPI versions the ‘S’ screw head is factory set and sealed.

If new adjustment is required, first make sure that the actuator is mounted on the valve and switched off.

Connect a suitable test circuit between terminals 8 and 9:

• Terminal contacts 8 and 9 opened: turn the adjustment screw clockwise until the contacts just are

closed. Now turn the adjustment screw one full turn counterclockwise.

• Terminal contacts 8 and 9 closed: turn the adjustment screw counterclockwise until the contacts are

opened. Turn the adjustment screw clockwise until the contacts just are closed. Now turn the adjustment

screw one full turn counterclockwise.

Energise the actuator and cycle on/off. The terminal contacts 8 and 9 have to be opened in the off position of

the actuator. Otherwise repeat the adjustments and cycle on/off. Finally seal the screw head and remove the

test circuit.
