ATTENTION
In the case of phase-phase feed, a
bridge must be fitted on the control
box terminal board between termi-
nal 6 and the earth terminal.
Do not swap neutral and phase over, follow the diagram shown care-
fully and carry out a good earth connection.
The section of the conductors must be at least 1mm². (Unless requested oth-
erwise by local standards and legislation).
The electrical wiring carried out by the installer must be in compliance with
the rules in force in the country.
Verify that the burner stops by operating the boiler control thermostats and
that the burner locks out by separating the red ionisation probe lead connec-
tor.
NOTES
The burners have been type-approved for intermittent operation.
This means they must stop at least once every 24 hours in order to allow the
electrical control box to check its efficiency on start-up. The boiler limit thermo-
stat (TL) normally ensures the burner halts. If this does not happen a time
switch halting the burner at least once every 24 hours must be applied in series
to limit thermostat (TL).
