the conditions of the system (any narrowing of the connections; the appliance supply pressure is stated on the plate) or of
the pressure regulator fitted to the gas bottle.
The appliance is in category one (I3+ or I3B/P), so no transformation for use with other types of gas is possible. The dismantling of
the injectors for switching to other types of gas is not allowed.
Special maintenance
Any special maintenance to the hob must be carried out by authorised personnel.
It is possible to replace the components inside the hob.
To access the inside of the hob, it is necessary to remove it from the unit. At this point the hob components are accessible: valves,
burner cups, tubes and gas ramp (see figure 4).
Replace everything necessary, always fitting original parts supplied by Technical Assistance. The washers in contact with gas
(e.g.: those of the valves) must always be replaced when implicated in disassembly).
Restore any seals when the replacement operation is complete.
If it becomes necessary to replace the injectors, see the TECHNICAL FEATURES section. No sealant is used between the injector
thread and its seat.
Figure 4
Refit the appliance, fastening the glass of the hob using the collar under the knob and the heat grids/flanges. Pay attention when
centring the burner with respect to the corresponding holes in the glass hob. Correctly reposition all the washer, to prevent direct
stress by metal parts on the glass.
Greasing the valves: if the rotation of the knob becomes difficult, it is necessary to grease the valve to prevent damage. Proceed
as follows:
-
dismantle the valve from the gas ramp and the internal tubes;
-
dismantle the body of the valve;
-
remove the conical male element, cleaning it with thinner;
-
lightly re-grease the cone using appropriate grease;
-
introduce the cone into its seat, manoeuvring it to expel any excess grease. Remove the excess grease with a cloth;
-
remove the cone again to ensure that the grease has not blocked the internal gas passages;
-
refit the valve.
