When the appliance is connected, turn it on and check the
gas pressure.
Check gas pressure directly on the valve, as described
below:
•
Unscrew screw "P" on the pressure outlet of the valve.
•
Apply the pressure gauge to the pressure outlet.
•
Regulate gas pressure to the values of table 2 by adju-
sting the pressure reducer outside the oven
•
When the pressure is at the correct level, switch off
the oven, remove the pressure gauge and replace
screw "P".
If the adjustment of the pressure is not sufficient, act as
follows:
•
Remove the protective cap A.
•
Screw to increase the pressure of the outlet gas acting
on the screw B and unscrew to decrease.
•
At the end of the calibration reapply the protective
cap A.

For connection to a type of gas that is different from the
one specified on the rating plate, the burner/s and nozzle/s
must be replaced as follows:
•
Unscrew nozzle to be replaced and replace it with the
one that corresponds to the type of gas to be used.
•
Refit washer.
•
Nozzles are marked in hundredths of a millimetre.
•
After replacing the nozzle/s, check gas pressure.

1.5 Electric connection

The electric system, as prescribed and specified by the Standard in force, must be
equipped with an efficient ground. It is possible to guarantee the electric safety of the
appliance only in the presence of Standard electric system.
For direct connection to the mains, it is necessary to interpose a device between the
equipment and the same mains, sized for the load, that ensure its disconnection. The
contacts must have an opening distance enabling the full disconnection, in conditions
of over-voltage category III, per compliance with installation regulations.
This device also must be located in a place and in a manner to be easily accessible at
any moment by the operator.
Bring the main switch, to which the power supply cable plug will be collected, in position
0 (zero).
Have professionally qualified staff check that the plug cables section is adequate to the
power used by the appliance.
Loosen the screws fixing the left side of the oven and extract it.

nominal voltage value by ±10%.
The equipment must be included in an equipotential system which efficiency must be
checked according to that reported in the Standard.
For the connection there is a clamp, located on the frame and marked with the symbol
to which a cable with minimum section of 10 mm² must be connected.
For gas ovens, complete gas connection to the appliance before assembling the
oven side again;
for electric ovens assemble the oven side.
Use and maintenance manual
Connect the cable to the terminal board
following the indications on "tab 1".
Lock the cable with the cable presser.
