made according to current standards. It is necessary to check this fundamental safety requirement. In the event of
doubt, have the electrical system checked by qualified personnel. Do not use the gas tubes as an earthing system
for electrical devices.
 Do not touch the device with wet or damp body parts and/or in bare feet.
 Do not pull the electric cables.
Installation
The gas trains are intended to be fitted to the left of the burner: if
fitted to the right, it is necessary to move the minimum gas pres-
sure switch 1)(Fig. 1, page 4) and (if present) the valve leak de-
tection control device 3)(Fig. 1, page 4) on the side opposite to
the valve group.
It may be necessary to place an adapter between the gas train
and the burner (see the burner manual) if the diameters of the
train are different from those for which the burner is set up.
To avoid excess strain it is advisable to support
bigger trains using an appropriate support.
WARNING
Do not, under any circumstances, install the valve
with the coil facing down.
