USE
otes:
use of a gas cooking appliance produces heat and moisture in the room in which it is installed. The
room must therefore be well ventilated by keeping natural air vents clear and by activating a
mechanical aeration device (suction hood or electric fan).
Intensive and lengthy use of the appliance may require additional ventilation. This can be achieved
by opening a window or by increasing the power of the mechanical exhausting system if installed.
Abnormal operations:
Any of the following are considered to be anormal operation and may require servicing:
- yellow tipping of the hob burner flame.
- Sooting up of cooking utensils.
- Burners not igniting properly.
- Burners failing to remain alight.
- Burner extinguished by cupboard doors.
Do not place anything, eg. flame tamer, asbestos
mat, between pan and pan support as serious
damage to the appliance my result.
Do not remove the pan support and enclose the
burner with a wok stand as this will concentrate and
deflect heat onto the hotplate.
Do not use large pots or heavy weights which can
bend the pan support or deflect flame onto the
hotplate.

installation instructions, local gas fitting regulations, municipal codes, electrical wiring regulations, AS 5601 -
Gas Installation and any other statutory regulations.
Ventilation must be in accordance with AS 5601 - Gas Installation. In general, the appliance should have
adequate ventilation for complete combustion of gas, proper flueing and to maintain temperature of
immediate surroundings within safe limits.
The wall and bench surfaces must be capable of sustaining temperatures of 75 °C.
All laminates, fixing adhesive and surfacing materials should be certified suitable for this temperature.
INDICATIONS FOR INSTALLATION
●The device is designed to remain operational for less than 24 h (non-permanent operating system). When
this limit is reached, a regulation stoppage occurs so the device can check its efficiency.
●This automatic device is a safety device and must not be altered. nterference with this device will eliminate
any responsibility by the manufacturer and invalidate the warranty.
●Observe the national and European standards applicable (e.g., EN 60335-1/EN 50165) in relation to
electrical safety.
●Before entry into operation, check the wiring carefully: incorrect wiring may damage the device and
jeopardise the safety of the system.
●Connect and disconnect the hob only after cutting off the electricity supply.
●Avoid exposing the device to drops of water.
●Avoid laying the valve wires along with the high voltage wires of the ignition transformer.
●Ensure that there is nothing on the hob, particularly on the area of the control panel, before switching on.
●After switching on the hob, wait a few seconds to complete the automatic calibration procedure of the
control panel.
● n the event of a “partial” short circuit or insufficient insulation between the line and earth, the voltage on the
sensor electrode may be reduced so much that it causes the device to lock, due to the impossibility to
sense the flame signal.
●The extra low voltage (ELV) circuit is not safe to touch (only main insulation in compliance with
EN 60730-1), so the installation must guarantee the level of protection against electric shock equivalent to
double insulation for the user interface.

REGULATION
7) PROCEDURE FOR REGULATING THE INI U
CAPACITY OF THE BURNERS
The procedure for acquiring the minimum capacities allows the modification of the
minimum capacity programmed, adapting every burner to the characteristics of
the gas distribution network to which the hob is connected.
The procedure is activated by pressing the + and - buttons of burner 3 together
with the + and - buttons of burner 1 continuously for 3 seconds, with all the
burners switched off (standby).
The activation of the regulation procedure is indicated on the display with the
word “M N”. At this point it is possible to select the burner to be regulated using
buttons 12 and 13 (- and + of the clock programming), after confirmation with the
Clock button (11), the burner selected ignites at the minimum and the capacity
can be increased or decreased to the minimum level using the + and - buttons of
the burner. During the display regulation procedure, the flame display levels will
show the indication ‘-’ if the minimum level programmed corresponds with the
factory setting, and the indication will change ^ or v in flashing mode, indicating a
higher or lower capacity than that programmed.
To confirm the minimum capacity required, it is necessary to press the Clock
button (11). The word “M N” will continue to be present and none of the leds will
flash. At this point it is possible to press the Clock button (11) to exit the
procedure, or press buttons 12 and 13 to select another burner and programme
its minimum capacity. The minimum capacity levels will then be acquired and
memorised by the device, and will be used in the normal use of the hob (see

programmed for the burners (see fig. 9).

10) REPLACING NOZZLES
The burners can be adapted to suit different types
of gas by fitting the nozzles that correspond to the
gas used. To do this, it is necessary to remove the
burner heads and use a tubular spanner “B”, to
unscrew the nozzle “A” (see fig. 10) and replace it
with a nozzle corresponding to the gas used.
We advise you to block the nozzle tightly.
After making these replacements, the
technician must regulate the burners as
described in paragraph 7 - 8 - 9, seal any
regulation or pre-regulation organs and apply
the label corresponding to the new gas
regulation carried out on the appliance in place
of that previously applied. This label is
contained in the spare nozzle bag.
For the ease of the fitter, we have prepared a table
indicating the flow capacities, the heat capacities of
the burners, the diameter of the nozzles and the
working pressure for the various types of gas.

Display of the temperature inside the hob
There is a temperature sensor inside the electronic card with which it is possible
to show the temperature inside the hob directly on the timer display. The display is
activated by pressing the + and - buttons of burner 1 together with buttons 12 and
13 continuously for at least 3 seconds. n this condition it is no longer possible to
use button 11 for settings related to the programming of the burner switch-off time.
The same sequence of buttons used to activate the inner display of the
temperature must be used to deactivate it.
Electronic self-diagnosis
The electronic cards constantly control their own status. Should hardware problems
or faults inside the card occur, such as to jeopardise the safety of the end user, the
device enters a “safe” status in which the solenoids are switched off and a code
relating to the type of fault appears on the display.

To replace the components housed inside the hob it is necessary to remove the flanges by loosening the
screws (fig. 11), removing the ceramic glass surface.
After carrying out the operations listed above, it is possible to replace the solenoids (fig. 12 - 13), the
electrical components and the electronic card (fig. 14 - 15).
We advise you to change the seal “D” every time you replace a solenoid, in order to guarantee a perfect
seal between the body and the ramp.
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.
