Notes on safety for the electrical wiring
Before carrying out any maintenance, cleaning or checking oper-
ations:
If the cover is still present, remove it and proceed with the electri-
cal wiring according to the wiring diagrams.
5.11.2
Control box
To remove the control box from the burner it is necessary to:
disconnect all the connectors connected to it, the 6-pin plug,
the high voltage cables, and the earth wire (TB);
loosen the screw 1)(Fig. 16) and pull the control box in the
direction of the arrow.
For the installation:
tighten screw 1)(Fig. 16) with a tightening torque of
1 ÷ 1.2 Nm;
reconnect all previously disconnected connectors, making
sure to connect the 7 pin power plug as the final step.
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.
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. Do not use the gas tubes as an earthing system
for electrical devices.
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
Turn off the fuel interception tap.
DANGER
Avoid condensate, ice and water leaks from form-
ing.
DANGER
Disconnect the electrical supply from the burner
by means of the main system switch.
After carrying out maintenance, cleaning or
checking operations, reassemble the cover and
all the safety and protection devices of the burner.
