REPLACING THE MOST IMPORTANT COMPONENTS

This should only be done by an "Authorized Service Centre"!!.
To be able to change the following components you must firstly:
- shut off the gas supply inlet valve
- remove the knobs
- take off the front panel
- if necessary, remove the grills, burner lids and burners.
It is now possible to replace the most important components.
A) Worktop burner thermocouple (Fig. 2)
- unscrew the nut (7) with a size-8 wrench
- unscrew the nut (Fig. 1 pos. 4) with a size-9 wrench
- install a new thermocouple of the same type, following the reverse order to disassembly
B) Worktop cock (Fig. 1)
- unscrew the nut (4) with a size-9 wrench
- disassemble all the gas connections
- install a new cock following the reverse order to disassembly.
N.B.: Check there are no gas leaks with the soap solution method; the seal must be perfect.
C) Oven thermostat (Fig. 5)
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. 6 position 6 and Fig. 4 position 16)
- remove the oven bottom;
- unscrew the thermostat nut with a size-9 spanner (Fig. 4 position 16);
- unscrew the nut (Fig. 3 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. 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.
