CARRIED-OUT

TO BE DONE BY
THE INSTALLER
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 se-
ries to limit thermostat (TL).
