
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).
