INSTALLATION ANDFINAL CHECKOUT
Warning
:
Take c are thatinstaller is a trained
experienced service man.
:
Turn off gas supply before starting
installation.
:
Disconnect p ower supply to
prevent elec trical shock and/or
equip ment d amage.
Mounting position
The gas valve can be mounted plus or
minus 90 degrees fromthe vertical.
Mounting location
The distanc e between the gas valve
and the wall/ground, must be at least
30 cm.
Main gas connection threaded
valves
:
Take c are that dirt cannot enter the
gas valve during handling.
:
Ensure the g as 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(BS21, DIN
2999) or a piece of new, properly
reamed pipe, free fromswarf.
:
Do not thread or tighten the pip e 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.PTFEtape may be
used as an alternative.
:
Inordertotightenthepipeinthe
valve, d o not use the actuator as a
lever b ut use a suitable wrench
operating on the wrench bosses.
Main gas connection flanged valves
:
Take c are that dirt cannot enter the
gas valve during handling.
:
Ensure the g as flows in the same
direction as the arrow on the housing
of the gas valve.
:
Ensure thatinlet and outlet flanges
are in line and separated fromeach
other enoug h to allow the valve to be
mounted between them without
damaging the gasket.
:
Place gasket. If nec essar y grease it
slightly to keep it in place.
:
Mount gas valve between flanges
using the b olts for each flange.
Warning
Tightness test after installation
:
Paintall pipe connections and
gaskets with a strong soap and
water solution.
:
Start the appliance and check for
bubbles. If a leak is found in a p ipe
connection, remake the joint.
A gasket leak can usually be
stopp ed by tightening the mounting
screws. Otherwise, replac e the gas
valve.
Electrical connection
Caution
:
Switc h off p ower supply before
making electrical connections.
:
Take c are that wiring is in
accordance with local regulations.
Use lead wire which can withstand
105
E
C ambient.
The electric on/off operator is provided
with a terminalbloc k for elec trical
connections.
Wiring
Follow the instructions supplied by the
appliance manufacturer.
Final checkout
Setappliance in operation and observe
several complete c ycles to ensure that
components function correctly

CONSTRUCTION AND WORKING PRINCIPLES
The VG series safety solenoid valves
are class A fail safe shutt--off valves.
The valve can be opened manually
afterenergizing the operator.
The operator consists of a coil and c oil
housing. Through this op erator moves
a shaft which is connected to the
closing member.On this shafta disc is
mounted which can be moved towards
the coil by pulling the setting knob and
will be kept in that position when the
operator is energized.
De--energizationwill cause the spring
loaded closing member to close.
A strainer made out of steel according
to AISI 303 is incorp orated in the valve.
Valve closing spring is mad e out of
steel ac cording to AISI 302.
Sealsand gaskets aremanufactured
out of hydrocarbon NBR resistantare
according to DIN 3535 and EN 291.

STANDARDS ANDAPPROVALS
Standards
The VG series safety solenoid valves
have been designed to meet the
Europ ean Standard EN 161.
The safety solenoid valve meets class
A requirements.
According to bending stress the safety
solenoid valve meets the highest
requirements.
Regarding electric safety, the VG series
safety solenoid valves can be used in
appliances acc ording to European
Standard for a household electrical
requirements EN60335 series and
industrial applications.
The VG series safety solenoid valves
also meet allElectro Magnetic
Compatability standards for
non--industrialand industrial
appliances.
Approvals
The VG series safety solenoid valves
confirm with the following
EC--directives:
:
Gas Appliance Directive
(90/396/EEC)
:
Low Voltage directive (73/23/EEC)
The fact thatthe VG series safety
solenoid valves are certified to
Europ ean Standard EN 161 means that
this series meets morestringent
requirementsthan laid down in the
essential requirementsstated in the
directives and thereforemeets the
requirements in all EC and EFTA
countries.
Details can be found in the approvals
list.
The registrationnumber specific for
each O.S.number is mentioned on the
label of the safety solenoid valve.
