Electrical Connection
The appliance must be connected to the elec-
trical mains by qualifi ed personnel and in con-
formity with statutory legislation.
The voltage of the electric supply must corres-
pond to the value indicated on the label affi xed
to the underside of the appliance.
Make sure that the electric system has an ef-
fi cient earth connection in compliance with re-
gulations and legislation. This appliance must
be earthed.
IMPORTANT: if the household electrical system
does not meet specifi cations or does not have
an effi cient earth connection, the appliance will
not operate.
If the appliance is not fi tted with a plug, con-
nect a standard plug to the power cable.
If the appliance is to be wired directly to the
mains supply, a disconnect device must be in-
terposed having a suffi cient contact gap to al-
low complete isolation also in category III surge
conditions, in accordance with installation re-
gulations.
In case of a power failure, the appliance will
not operate and the burners cannot be lit using
matches or external igniters.
However, the appliance can continue to operate
correctly if the power cord is connected to an
uninterruptible power supply. In this case, ope-
ration is normal.
Gas conversion and adjustments
If the appliance is prearranged for a type of gas
different from the available type, the burner
nozzles must be changed and the control card
must be set up with the parameters relative to
the new confi guration.
Changing the nozzles
Choose the required nozzles with reference to
the following “Technical Specifi cations” table.
Proceed as follows:
– Remove the pan stands and burners from the
hob.
– Unscrew nozzles U (fi g.6) and U1/U2 (fi g.7)
using a socket spanner (L), and replace with
the correct nozzle for the available gas type.
– Secure the nozzle without over-tightening.
