DANGER
The electrical wiring must be carried out with the electrical supply disconnected.
Electrical wiring must be made in accordance with the regulations currently in force in the country of destination
and by qualified personnel. Refer to the wiring diagrams.
The manufacturer declines all responsibility for modifications or connections different from those shown in the wir-
ing diagrams.
Do not invert the neutral with the phase in the electrical supply line.
Check that the electrical supply of the burner corresponds to that shown on the identification label and in this man-
ual.
The burner has been type-approved for intermittent use.
In the event of continuous operation, a cycle arrest must be ensured within 24 hours with the use of a time switch
positioned in series with the thermostatic line. Refer to the wiring diagrams.
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.
The electrical system must be suitable for the maximum power absorption of the device, as indicated on the label
and in the manual, checking in particular that the section of the cables is suitable for that level of power absorp-
tion.
For the main power supply of the device from the electricity mains:
- do not use adapters, multiple sockets or extensions;
- use a multiple pole switch with at least a 3 mm gap between the contacts (overvoltage category III), as envis-
aged by the present safety standards.
Do not touch the device with wet or damp body parts and/or in bare feet.
Do not pull the electric cables.
DANGER
Disconnect the electrical supply from the burner
by means of the main system switch.
DANGER
Close the fuel interception tap.
DANGER
Condensation, the formation of ice and the entry
of water are prohibited!
After carrying out maintenance, cleaning or
checking operations, reassemble the cover and
all the safety and protection devices of the burner.
