Checking the correct operation of the burners
When the appliance is installed, check that all the burners work properly.
Check the ignition, in compliance with the Instructions for Use section, the stability of the flame, the maintenance of the flame
when turning the knob from maximum to minimum. The flame must not flare up or go out.
If this happens:
-
check the type of gas/pressure used: it must correspond to that indicated on the appliance plate;
-
check for any shifting of the burner parts (flame divider, cap), due to assembly of the appliance.
If the problem persists, contact Technical Assistance.
Ventilation
This appliance is not connected to a device for the evacuation of the combust products. Therefore, it must be connected in
compliance with the installation standards in force. Pay particular attention to that envisaged by local legislation on the matter of
ventilation ad aeration.
Specifically (UNI 7131), the room where the appliance is installed:
-
must be fitted with a system to take the combustion fumes outside, through a hood or electric fan which starts operating
automatically every time the appliance is switched on;
-
it must have a system which allows the air flow necessary for proper combustion (at least 2 m
3
/h for each kW of installed
power). This can be obtained by taking the air directly from outside (section of at least 100 cm
2
, in order to prevent it
becoming accidentally blocked), or indirectly from adjacent rooms (not bedrooms or rooms where there is a risk of
explosion) which are directly ventilated and connected to the former by permanent openings.
The appliance is fed by LPG (liquid petroleum gas).
LPG is heavier than air, so it settles downwards. Consequently LPG bottles must have an opening towards the outside to allow
low-level evacuation of any gas leaks.
Empty r partially full LPG bottles must not be installed or kept in rooms or
areas that are below ground level (cellars, etc.).
Only gas bottles that are being used may be kept in said rooms/areas, in a position where they are not subject to the direct action
of sources of heat (50°C).
Adjustments and transformations
No adjustment is necessary:
-
the burners are fixed primary air burners;
-
as the only power supply is LPG (in compliance with that indicated on the plate on the underside of the appliance), the
minimum levels have already been set in the factory. The valve by-pass screw has already been fully tightened. Should an
inadequate flame be found in the Minimum position during use, intervention on the by-pass valve screw is forbidden. Check
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.
