Electrical connection

The appliances in the series .....FV or ....FE are delivered with a power cable without a plug or even without a cable. A
correct connection must observe the laws in force and must be carried out by connecting a standardised plug to the
cable, knowing that the yellow-green wire is the earth wire. If a direct connection to the mains is required, an omnipolar
switch has to be installed between the appliance and the mains. The switch is to be dimensioned for the load and its
contacts must have a minimum opening distance of 3 mm. The yellow-green earth wire must not be interrupted by the
switch.
NOTE: The type of connection cable is indicated in TABLE 3.
The power supply terminal is located under the right panel of the kitchen (FE series) and the left side bottom (FV
series)
UNIPOTENTIAL
The appliance must be connected to a unipotential system.
The terminal provided is situated at the rear, near the cable inlet, and is marked by a label.

3. TECHNICAL FEATURES (Relating to the GAS part)

The data plate is positioned on the base of the cabinet or on the panel under the oven.

4. OPERATION WITH SUPPLY GAS IDENTICAL TO THAT AVAILABLE

Check whether the indications on the data plate correspond to the gas distributed. Also check the correspondence of
what is indicated below.
4.1

Checking the supply pressure (Fig. 2)

The supply pressure must be measured by means of a pressure gauge with a U-shaped pipe or of the electronic type with
minimal grading of 0.1 mbar.
Unscrew the screw "A" from the pressure tap "B".
Position the pressure gauge.
Switch on the appliance and check whether the pressure is the one intended: if not check on the cause.
At the end of the operation, reassemble the appliance and check on the connection
ATTENTION: If the pressure measurement is not within the thresholds stated in table 4, instead of installing the appliance
you should contact your gas provider to report a fault with your mains supply.
Close the gas valve, disconnect the pressure measurement device, do up the screw you had previously undone and
close the front panel.
4.2

Regulating the primary air

The primary air must be regulated taking into account the indications of tables 2.
5.

REGULATION FOR OPERATION WITH OTHER TYPES OF GAS

To carry out this operation, for example in order to change from natural to liquid gases, the injectors of the main burners
and of the pilot flames have to be changed and the by-pass of the minimum regulated (see tables 2).
All the injectors required for regulation are supplied in a small bag together with the appliance. The injectors of the main
burners are marked in hundredths of a millimetre.
5.1

Replacing main burner injectors

Pull the knobs.
Remove the dashboard by attaching the fixing screws at the bottom of the bracket.
Replace the ugellocon that suitable for the new type of gas.
5.2

Replacing the FG 4 kW oven injector

Extract the bottom of the oven.
Unscrew and replace the nozzle with the one suitable for the new type of gas.
5.2.1

Air regulation

Loosen the fixing screw.
Adjust the primary air with the bracket at the distance indicated in Table 2.
Lock the bracket by tightening the fixing screw
5.2.2

Regulating the minimums

Remove the knob and regulate the flame to the minimum setting until a stable and even flame is obtained. For the
suitable capacity see tables 2.
For operation with liquid gas, the adjusting screw "F" must be fully unscrewed.
5.3

Replacing the STILE UNICO Series oven burner injector.

Extract the bottom of the oven
5.3.1

Pilot flame (Fig. 7)

If the pilot flame has been regulated correctly it should envelop the thermocouple and have a perfect exterior appearance.
If this is not the case, unscrew the screw "G" and check that the injectors installed are the right ones (see tables 2).
Regulation of the primary air is not necessary for the pilot flame.
5.3.2

Main burner (Fig. 8)

Unscrew the "I" injector and fit the 12 mm wrench. After making the conversion, the sticker (fig.1) must be attached to the
plate, in the appropriate space, the adhesive indicating the new type of gas that can be used. The appliance must be
used by certified personnel, as this appliance is intended exclusively for professional cooking
