ELECTRICAL WIRING

All the installation, maintenance and disassembly operations must be carried out with the electricity sup-
ply disconnected.
WARNING
The burner requires periodic maintenance carried out by a qualified and authorised technician in con-
formity with legislation and local standards.
DANGER
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 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 connector.
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 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).
