7 E E - 7 Safety Instructions Definition of symbols This symbol indicates cautionary information. The statements WARIG, ATTETIO, CAUTIO indicate a potentially hazardous situation with the risk of property damage, injuries or death. WARIG: 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. CAUTIO: 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.

8 E E Installation WARIG: 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. CAUTIO: 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. IMPORTAT: 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. IMPORTAT: 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. IMPORTAT: Refer to valve label for mounting positions. 90 Maximum from Vertical Figure 1: Mounting position Limited Horizontal and Vertical 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.

9 E E - 9 Wiring WARIG: 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.

Checkout Procedure WARIG: 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. WARIG: 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.

11 E E - 11 Adjustments WARIG: 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. WARIG: 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. MR Figure 2: Switches R S M M Maximum Flow Factory set: full flow Do not make any adjustments on the sealed grub screw! S Feed back position / CPI Factory set is approx. 0.5 mm OR Ignition Stage Factory set is approx. mm R Reduced Stage Factory set is approx. mm or 5.5 mm at models with ignition stage MR Manual Restart (switch is not illustrated) Factory set is approx. sec. running time Do not make any adjustments on the sealed screw! Do not adjust the switches S and R below 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. ow 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. ow 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.

12 E E In a similar way, the S switch can be used as an auxiliary signal switch for any actuator stroke position. Turn the S screw clockwise for a signal at a higher stroke or flow. Turning counterclockwise reduces stroke or flow level to activate the switch. To adjust the ignition flow, turn the S screw. Turn the screw clockwise to reduce and counterclockwise to increase the flow required for proper ignition. Switch R To adjust the reduced flow rate or low fire position, turn the R ( Reduced ) screw. Turn the screw clockwise to reduce and counterclockwise to increase the flow for stage one. Switch MR The switch MR for Manual Restart stops gas from being automatically released again after a power cut. For Manual Restart operate the red button on the terminal box cover for at least seconds to drive the gas valve to the open position, see Figure. Should the button not be held long enough the gas valve will automatically return to the closed position. switch MR Figure : switch MR for Manual Restart
