Electrical wiring
DANGER
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. Refer to the wiring diagrams.
The manufacturer declines all responsibility for modifications or connections different from those shown in the
wiring 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
manual.
The burners have been set for intermittent operation. This means they should compulsorily be stopped at least
once every 24 hours to enable the control box to perform checks of its own start-up efficiency. Normally, burner
stopping is guaranteed by the boiler's thermostat/pressure switch.
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 input power of the device, as indicated on the label and
in the manual, checking in particular that the section of the cables is suitable for the input power of the device.
For the main power supply of the device from the electricity mains:
– do not use adapters, multiple sockets or extensions;
– use an omnipolar switch, as indicated by the current 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
Turn off the burner's power supply using the main
system switch.
DANGER
Turn off the fuel interception tap.
DANGER
Avoid condensate, ice and water leaks from form-
ing.
After carrying out maintenance, cleaning or
checking operations, reassemble the cover and
all the safety and protection devices of the burner.
DANGER
All the installation, maintenance and dismantling
operations should be performed voltage free.
The replacement of the control box must be per-
formed by qualified personnel, as indicated in this
manual and in accordance with standards and
regulations in force.
