MAINTENANCE
Before carrying out any maintenance,
disconnect the appliance from the gas and
electricity supplies.
11) REPLACING COMPONENTS
To replace the components housed inside the hob
it is necessary to remove the flanges by loosening
the screws (fig. 16), removing the ceramic glass
surface.
After carrying out the above operations, it is
possible to replace the burners, the valves (fig. 17
- 18) and the electrical components (fig. 19).
We advise you to change the seal “D” every time you
replace a valve, in order to guarantee a perfect seal
between the body and the ramp.
Greasing the valves (see fig. 20 - 21)
If the movement of a valve becomes stiff, grease it
immediately following the instructions below:
- dismantle the body of the valve.
- Clean the cone and its housing with a rag soaked
in thinners.
- Lightly grease the cone using appropriate grease.
- Insert the cone, manoeuvre it several times,
remove it again, eliminate the excess grease and
ensure that the gas channels are not blocked.
- Re-assemble all the parts in reverse order.
To facilitate the work of the maintenance operator,
we have prepared a table, printed on the next page,
indicating the power cable types and sections.
