REPLACING THE MOST IMPORTANT COMPONENTS

The unit should be checked at least twice a year. You must check the burners, the ignition, the interignition, the maximum
and minimum settings. Moreover, you should check the good functioning of the windscreen/draft hood and the air inlet.
To be performed exclusively by an "Authorised Service Centre"!
In order to replace these components, it is important to first do the following:
- Shut off the gas supply inlet valve;
- Remove the knobs;
- Disassemble the front panel;
- Possibly remove the grills, the flame-spreaders and the burners.
Now you can replace the more important components.
A) Worktop burner thermocouple (Fig. 3 pos. 4)-(Fig.1)
- unscrew the nut (Fig.1 Pos.3) with a size-10 spanner
- unscrew the nut (Fig.1 Pos.3) with a size-9 spanner
- install a new thermocouple of the same type, following the opposite assembling order.
B) Worktop burner cock (Fig. 1)
- Remove all the knobs and the dashguard;
- disassemble all the gas connections (4-3-6);
- Unscrew all the screws (5) with a size-7 spanner
- install the new cock following the reverse order of assembling;
N.B.: Check for gas leaks with bubble soap: sealing must be perfect.
C) Oven thermostat (Fig. 4).
The thermostat is located on the supply backguard.
- Remove all the knobs and the dashguard.
- disassemble the thermocouple (16) with a size-19 spanner;
- first remove the gas outlet towards the burners (nut with Bicone)(13);
- remove the bulb inside the oven, which is fixed by bulb-holder brackets;
- disassemble the bridle (12) that blocks the thermostat to the ramp gas:
- install a new thermostat following the reverse assembling order;
- change the idle bypass screw (17);
- install the bulb into the oven using its brackets.
N.B.: Check for gas leaks using bubble soap: sealing must be perfect.
D) Oven thermocouple (Fig.6 position 8)
- Remove the oven bottom;
- dismantle the protective box
- dismantle the protective box
- unscrew the thermostat nut with a size-9 spanner (Fig. 4 position 16);
- unscrew the nut (Fig. 6 position 16) with a size-10 spanner;
- install a new Targhet thermocouple, following the opposite assembling order.
N.B.: Unified SIT thermocouple: should be kept 4 or 5mm back in respect of its holder.
E) Oven pilot burner spark-plug (Fig. 6 position 5)
- Remove the oven bottom;
- detach the high-voltage wire;
- remove the spark plug by unscrewing the nut with a size-10 spanner;
- install the new spark plug, following the opposite assembling order.
F) Oven and/or Plate piezoelectric igniter
It is very easy to disassemble the igniter from the oven dashguard:
- detach the high-voltage wire;
- unscrew the nut with a size-25 spanner;
- install the new piezoelectric igniter, following the opposite assembling order.
