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
equipment damage.
Mounting position
The gas valve can be mounted plus or minus 90 degrees from the
vertical.
Mounting location
The distance between the gas valve and the wall/ground, must be at
least 30 cm.
WARNING
!
The outlet of a pressure relief valve (VE4000S series) must
always be connected to the open atmosphere.
Main gas connection threaded valves
.
Take care that dirt cannot enter the gas valve during handling.
.
Ensure the gas flows in the same direction as the arrow on the
housing of the gas valve.
.
Use a sound taper fitting with thread according to ISO 7-1
(BS 21, DIN 2999) or a piece of new properly reamed pipe, free
from swarf.
.
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, PTFE
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 wrench operating on the wrench
boss.
Main gas connection flanged valves
.
Take care that dirt cannot enter the gas valve during handling.
.
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 other 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.
MU2C-0044SZ20 R0704
WARNING
!
Tightness test after installation
.
Spray all pipe connections and gaskets with a good quality gas
leak detection spray.
.
Start the application and check for bubbles. If a leak is found in
a pipe connection, remake the joint.
A gasket leak can usually be stopped by tightening the moun-
ting screws. Otherwise, replace the gas valve
Electrical connection
CAUTION
!
.
Switch off power supply before making electrical connections.
.
Take care that wiring is in accordance with local regulations.
Use lead wire which can withstand 105 °C ambient.
The electrical ON/OFF operator is provided with a terminal block for
electrical connections.
Wiring
Follow the instructions supplied by the appliance manufacturer.
ADJUSTMENTS AND FINAL CHECKOUT
WARNING
!
Adjustments must be made by qualified persons only.
VE 4... B series (see fig. 1)
Flow rate adjustment
.
Remove the cap screw from top of the coil.
.
Place a socket head wrench into the adjustment nut.
.
Turn wrench counter-clockwise to increase or clockwise to
decrease flow rate.
.
Replace cap screw.
CAUTION
!
To ensure a safe closing of the valves, it is essential that voltage
over the terminals of operators is reduced to 0 volt.
NOTE: The flow adjustment of the VE4100 series valves is at the
bottom of the valve.
VE 4... C series (see fig. 2 and 3)
The following characteristics can be adjusted:
.
flow rate
.
step pressure
.
opening speed
IMPORTANT
To ensure a satisfactory setting of the valve, the pressure
drop over the valve should be at least 10% of the supply
pressure or 2,5 mbar which ever is the greatest.
Flow rate adjustment (see fig. 2a and 2b)
.
Remove the cap from top of the coil by loosening both screws.
.
Place a wrench on the adjustment hexagon nut.
.
Turn wrench counter-clockwise to increase or clockwise to
decrease the flow rate.
.
Replace cap on top of the coil.
Step pressure adjustment (see fig. 2c)
.
Remove the cap from top of the coil by loosening both screws.
.
Place a screw driver in the slot of adjustment screw which is
situated in center of the valve.
.
Turn screw driver counter-clockwise to increase or clockwise to
decrease step pressure.
.
Replace cap on top of the coil.
