E.7.3
Testing the gas inlet pressure
The inlet pressure is measured upstream of the gas control
valve with the appliance operating (after eventual conversion
to a different gas supply) using a pressure gauge with
minimum resolution of 0.1 mbar.
To measure the gas inlet pressure, proceed as follows:
1. Open the control panel;
2. Remove sealed bolt "C" from the pressure point;
3. Connect the pressure gauge "M" pipe;
4. Make sure the pressure reading corresponds with the
values shown in the table below:
GAS TYPE
Nominal
G20 natural
20
gas
LPG (G30/G31)
28 – 30/37
Australia
GAS TYPE
Nominal
Natural gas
LPG
2.75
If the inlet pressure does not correspond with the
above values, the appliance will not function.
If this is the case, contact your local gas supplier
immediately.
5. Once the inlet pressure has been measured, stop the
cooking cycle and close the gas shut-off tap;
6. Disconnect the pressure gauge "M";
7. Retighten sealed bolt "C";
8. Close the appliance.
E.7.4
Conversion to different type of gas
IMPORTANT
The appliance is factory-set to the gas type
indicated on the adhesive labels affixed to both the
appliance and packaging.
To convert the appliance to a different gas supply,
scrupulously follow the instructions indicated below,
and use the injectors in the bag supplied with the
oven.
E.7.5
Testing the primary air on the main burner
The primary air flow rate is correct when the flame does not
detach when the burner is cold or backfire when the burner is
hot.
To adjust the primary air flow rate, proceed as follows:
1. Slacken screw "A" and adjust aerator "B" to distance "H";
2. Retighten screw "A".

Replacement of main burner injector
To gain access to the main burner injectors, remove the left
hand side panel.
1. Slacken screw "A" and undo injector "C";
2. Remove the injector and aerator;
3. Replace injector "C" with the one corresponding to the
type of gas supply;
The injector diameter is indicated in hundredths of a
millimetre on the injector body (i.e. a 3.5 mm ø injector is
marked 350).

4. Fit the new injector "C" in aerator "B";
5. Remount the assembly in its original position and tighten
down the injector.
E.7.7
Replacement of pilot burner injector
1. Remove ignition electrode "C";
2. Undo fitting "A" on the pilot line;
3. Remove injector "B" and replace with the one correspond-
ing to the type of gas supply;
The injector identification number is stamped on the
injector body.

4. Reconnect the pilot line with fitting "A";
5. Remount ignition electrode "C".
The gas shut-off valve is not fitted with a minimum adjustment
screw. The operation of the burner is therefore ON or OFF.
