Notes on safety for the electrical wiring
 The electrical wiring must be carried out with the electrical supply disconnected.
 Electrical wiring must be carried out by qualified personnel and in compliance with the regulations currently in
force in the country of destination.
 The manufacturer declines all responsibility for modifications or connections different from those shown in the wir-
ing diagrams.
 Check that the electrical supply of the train corresponds to that shown on the identification label and in this man-
ual.
 The electrical safety of the device is obtained only when it is correctly connected to an efficient earthing system,

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
they are assembled on the right, it is necessary to move the min-
imum gas pressure switch 1)(Fig. 1, page 4) and - if present - the
valve leak detection device 12) to the opposite side of 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.
