WARNING:

Do not swap neutral and phase over, follow the diagram shown
carefully and carry out a good earth connection.

The section of the conductors must be at least 1 mm
otherwise by local standards and legislation).

The electrical wiring carried out by the installer must comply with the
rules in force in the country.
IMPORTANT
The burners have been approved for intermittent operation.
This means that they must stop once every twenty four hours
to permit the electrical control box to check its efficiency at
start-up. Normally the boiler's limit thermostat (TL) ensures
the stopping of the burner. If this is not the case, it is neces-
sary to apply in series with the (TL) a timer switch that turns
off the burner at least once every twenty-four hours.
TESTING
 Check the burner has stopped by opening the thermostats.

Check that the burner has locked out during operation by
opening the connector (CN1) inserted in the probe's red wire,
located outside the control box.
