Electrical wiring
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. Refer to the wiring diagrams.
The manufacturer declines all responsibility for modifications or connections different from those shown in the wir-
DANGER
ing diagrams.
Do not invert the neutral with the phase in the electrical supply line. Any inversion would cause a lockout due to fir-
ing failure.
Check that the electrical supply of the burner corresponds to that shown on the identification label and in this man-
ual.
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 per-
form checks of its own start-up efficiency. Normally the boiler's thermostat/pressure switch ensures the stopping of
the burner.
If this is not the case, it is necessary to apply in series with IN a timer switch that turns off the burner at least once
every twenty-four hours. 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 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.
Before carrying out any maintenance, cleaning or checking oper-
ations:
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.
DANGER
After carrying out maintenance, cleaning or
checking operations, reassemble the cover and
all the safety and protection devices of the burner.
5.11.1 Control box
All the installation, maintenance and dismantling
operations should be performed voltage free.
The replacement of the control box must be per-
DANGER
formed by qualified personnel, as indicated in this
manual and in accordance with standards and
regulations in force.
To remove the control box (Fig. 13) from the burner follow of the
instruction:
loosen the screw 1), open the protection 2) and remove all
components.
Remove the coil 3).
Loosen the two screws 4).
Move a little the control box and remove the high voltage
