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 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, DIN2999) 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 bosses.
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 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.
WARNING
Tightness test after installation
Paint all 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 pipe connection, remake the joint. A gasket
leak can usually be stopped by tightening the
mounting 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 electric on/off operator is provided with a terminal block
for electrical connections.
Wiring
Follow the instructions supplied by the appliance
manufacturer.
