4.10.1 Notes on safety for the electrical wiring

 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-
DANGER
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.
Before carrying out any maintenance, cleaning or checking oper-
ations:
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
If the cover is still present, remove it and proceed with the electri-
cal wiring according to the wiring diagrams.
Installation

4.10.2 Ionisation current

The minimum current necessary for the flame control operation is
3 µA. The burner normally supplies a higher current value, so that
no control is needed. In any event, if you want to measure the ion-
isation current, you need to open the connector fitted on the red
wire and insert a microammeter as shown in Fig. 17.
