ELECTRICAL WIRING

4.1 ELECTRICAL SYSTEM,
ATTENTION:
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 1mm².

(Unless requested otherwise by local standards and legisla-
tion).
The electrical wiring carried out by the installer must be in

compliance with the rules in force in the country.
TESTING
Check the shut-down of the burner by opening the thermostats,
and the lock-out by opening the connector (CN3) inserted in the
red cable of the probe placed outside of the control box.
NOTES
The burners have been type-approved for intermittent opera-
tion. 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 thermostat (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).
