REPLACING IMPORTANT COMPONENTS

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)
- unscrew the nut (7) with a size-8 spanner
- unscrew the nut (Fig. 2 position 3) with a size-9 spanner
- install a new thermocouple of the same type, following the opposite assembling order.
B) Worktop burner cock (Fig. 2)
- unscrew the nut (3) with a size-9 spanner;
- disassemble all the gas connections (4-5-6);
- install the new cock following the reverse order of assembling;
- Pay attention to the bypass! Replace or invert the bypass idle screw.
N.B.: Check for gas leaks with bubble soap: sealing must be perfect.
C) Oven thermostat (Fig. 5) "For gas oven units only".
The thermostat is located on the supply backguard.
- disassemble the thermocouple (16) with a size-19 spanner;
- first remove the gas outlet towards the burners (13 and 15);
- remove the bulb inside the oven, which is fixed by bulb-holder brackets;
- remove the gas inlet (12) with a size-9 spanner;
- install a new thermostat following the reverse assembling order;
- change the idle bypass screw (11);
- 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. 4 position 6 and Fig. 5 position 16)
- remove the oven bottom;
- unscrew the thermostat nut with a size-9 spanner (Fig. 5 position 16);
- unscrew the nut (Fig. 4 position 6) 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. 4 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.
