1) BURNERS
n the surface of the hob, there is a serigraphic figure above each knob, indicating the burner to which
the knob refers. After turning on the gas at the main or opening the valve on the gas bottle, light the
burners as indicated below.
Switching on the Hob
To switch on the hob, press the N/ FF button constantly for at least 2 seconds. The hob will come on
and the displays related to the burners will show level zero, corresponding to the status of burners off.
Lighting a burner
To light the burner 2 (or the burner 4), press and release the + button of the burner you wish to light. You
have 3 seconds to press the + button again to light the burner at level 9, otherwise, if you press the –
button, it will be lit at level 5. The control system will now make a maximum of 3 attempts at intervals of 10
seconds.
Should the burner fail to light after the third attempt, it locks and the corresponding Led displays the letter
“b”. To release the burner, see the relative procedure further ahead.
Every burner for which the relative timer has not been programmed will switch off automatically after 4
hours of constant operation.
The ignition of the burner is also indicated by the relative indicator, which remains active the whole time
the burner is lit.
Regulating the burner flame level
With the burner lit, to increase the capacity level you must press the + button, while it is necessary to
press the - button to reduce the capacity level. To obtain a continuous variation in the capacity level, it is
sufficient to keep the + or - button pressed and release it at the level required. The capacity level varies
from 1 to 9.
5
USE
The Dual burner, instead, can be lit partially (internal ring) or completely (internal and external ring)
depending on which buttons are pressed to light the burner. In particular, to light the internal ring only,
press button 4, and then you will have seconds time to press button 4 again and light the burner at
level 7.
To light the internal and the external ring simultaneously, press button 2, and then you will have
seconds time to press button 2 again and light both burner rings at level 7.
If you wish to light the external burner ring when the internal ring is already lit, this will anyway involve
switching off the internal ring and then lighting it again.
The Dual burner, instead, can be adjusted in two ways depending on whether it is lit partially (internal
ring) or completely (internal and external ring). When the internal ring only is lit, press button 4 to
increase the capacity level, or press button to decrease it. To obtain a continuous variation in the
capacity level, you just need to keep button 4 or pressed and then release it at the required level.
The capacity level can vary from 1 to 7.
When the internal ring is lit together with the external one, to increase the capacity level you can press
button 2 or 4 indifferently, as the level variation will occur on both rings simultaneously, while to
decrease the capacity level press button 1 or (to obtain a continuous variation in the capacity level,
you just need to keep the button pressed and then release it at the required level). Also in this case the
capacity level can vary from 1 to 7.

Switching off a burner
To switch off a burner it is necessary to press the + and - button simultaneously for a moment.
The corresponding Led will display the letter “H” (hot) for a few minutes to indicate that the burner is hot.
Switching off all the burners
To switch off all the burners at the same time, simply press the N/ FF button. This will place the hob in
FF status.
Programming the burner switch-off time
It is possible to independently programme each burner to switch off automatically after a specific length of
time.
To programme the timer of a burner, press the Clock button (7). n time display the writing TIME will
appear. Now pressing - or + button of the burner to be timed, the writing TIME disappears and the writing
0:00 will appear. The burner selected is identified by the relative flashing indicator (flashing fast). The
timer display will indicate 0.00, meaning that the timer related to the burner selected is not active. To
programme the switch-off time of the burner selected, press the Clock button (7) again; the timer display
will indicate 0.00. The flashing digit to the left of the dot indicates the hours, while those to the right
indicate the minutes. By pressing buttons - and + of the burner selected it is possible to increase or
decrease the operating hours from 0 to 9. Keeping buttons + or - pressed (of the burner selected) the
change in the number of hours will take place continuously.
To specify the number of minutes, press the Clock button (7) again. The digits to the right of the dot will
start flashing. Set the minutes in the same way as indicated for the hours.
When programming the time it is possible to zero the current setting at any time by pressing buttons - and
+ (of the burner selected) together. A time equal to zero deactivates the burner timer. To confirm the time
shown on the display, press the Clock button (7). At this point, only the indicators of the burners with the
timer active continue to flash.
Press the Clock button (7) to return to timer programming mode and see the time remaining until switch-
off or to change the current settings. If no button is pressed for more than 10 seconds during
programming, the programming procedure is interrupted automatically and the main display returns. Any
settings being changed on the burner selected will not be lost and the relative time is active.
The timer can be programmed both with the burner switched off or lit, and the counter will start
immediately after the time programmed has been confirmed. When the time is up, the timed burner will be
switched off and a sequence of acoustic signals lasting 30 seconds will be emitted (this acoustic signal
can be stopped by pressing the Clock button (7).
If the user switches off a burner, the relative timer is deactivated.
6
USE
The Dual burner, instead, can be switched off in two ways depending on whether it is lit partially
(internal ring) or completely (internal and external ring). Both when the internal ring only is lit and when
the internal ring is lit together with the external one, press button 4 and simultaneously for a short
time to switch off the burner completely. In case the internal ring is lit together with the external one,
and you wish to switch off the external burner ring only, press button 2 and 1 simultaneously for a short
time.
It is possible to programme the timer of a lit burner only, and in the case of a Dual burner, this
possibility is limited to the internal ring.
The timer programme of a Dual burner will always be effective after switching off the burner
completely, both in case the internal ring only was lit and in case both burner rings were lit.

7
USE
Regulating the clock
Following interruptions to the power supply, it is necessary to set the time displayed by the clock inside
the hob.
To regulate the clock, press the buttons 7 and 8 together for at least 3 seconds.
The flashing digit to the left of the dot indicates the hours, while those to the right indicate the minutes. It
is possible to increase or decrease the hours using buttons 2 or 1 and by keeping buttons 2 or 1 pressed
the change in the number of hours takes place continuously.
To regulate the minutes, press the Clock button (7) again. The digits to the right of the dot will start
flashing. Now change the minutes in the same way as indicated for the hours.
Press the Clock button (7) to memorise the time programmed.
Releasing the burner
When a burner is locked the relative display shows the letter “b”. The burner is released by pressing
buttons 1 and 8 together constantly for at least 2 seconds. When released, the burners are reset to level
0, ready to be lit again.
N.B: if the release procedure is repeated 5 times in a row during a 15 minute time span, the device will
indicate FLT06 and will accept no further request for release for another 15 minutes.
Locking the control panel
This is activated by pressing button 8 only for at least 2 seconds. All burner levels will remain stable. The
control panel locked status occurs when the decimal points on the display of the capacity level related to
each burner light up. While the control panel is locked it is no longer possible to change the levels of the
burners or change the timer settings, but it is possible to switch off the hob by pressing the N/ FF
button (safe switch-off).
It is not possible to release a locked burner when the control panel lock is active. It will be therefore
necessary to release the control panel before activating the burner release procedure.
Releasing the control panel
The control panel is released by pressing button 8 and button 2 for at least 2 seconds. The control panel
is released when the flame level points on the display go out.
Child lock function (for the hobs with DUAL burner).
It is activated only with hob off by pressing the button 8 for at least seconds. The activation of the
Child Lock function is visible through the switching on of the decimal points on the flow rate level
displays of each burner and entails the complete lock of the keyboard.
The function is deactivated by pressing again the button 8 for at least seconds (the unlock of the
keyboard is visible through the switching off of the decimal points on the flow rate level displays).
It is not possible to release a locked burner when the control panel lock is active. It will be therefore
necessary to release the control panel before activating the burner release procedure.

CLEANING
CAUT ON:
before cleaning the appliance, disconnect it
from the gas and electricity supplies.
2) WORKTOP
It is very important to clean the hob every time you
use it, while the glass is still warm.
Do not clean using abrasive metal scourers, powder
abrasives or corrosive sprays.
Depending on the degree of dirt, we recommend:
- for light stains, a damp sponge is sufficient.
Be aware that the razor can cause wounds.
- Traces of liquid spilled from pans can be
eliminated with vinegar or lemon juice.
- Never allow sugar or sugary foods to fall on the
hob while cooking. Should this occur, switch off
the hob and clean it immediately with hot water.
- As time goes by metallic reflections, colouring or
scratches may appear due to poor cleaning and
the incorrect movement of pans. Scratches are
hard to eliminate but do not affect the correct
operation of your hob.
Periodically wash the hot plate, the enamelled stell
pan support, the enamelled burner caps “A”, “B”
and “C” and the burner heads "T" (see fig. 4 and
5) with lukewarm soapy water. They should also
be cleaned plugs "AC" and flame detection "TC"
(see fig. 4). Clean them gently with a small nylon
brush as shown (see fig. 6) and allow to dry fully.
Do not wash in the dishwasher. It is very important
to clean the surface soon after every use, when
the glass is still tepid.
Do not allow vinegar, coffee, milk, salted water,
lemon or tomato juice from remaining in contact
with the enamelled surfaces for long periods of
time.
WARN NGS:
comply with the following instructions, before
remounting the parts:
●check that burner head slots “T” (fig. 4) have
not become clogged by foreign bodies.
●Check that enamelled burner cap “A-B-C”
(fig. 4-5) have correctly positioned on the
burner head. t must be steady.
●Burned food on an electric plate must be
removed dry.
●After use, pour a little lukewarm oil on the
plate and wipe it with a cloth.
●The pan support must be placed in the
appropriate centering pins verifying the
perfect stability.
●
Correctly preserve the plate after use by
treating it with special products, easily
available at the supermarket. This will keep
the surface of the plate clean and bright. This
operation will also prevent the formation of
rust.
●Don’t use steam jets for the equipment
cleaning.
Note:
continuous use could cause the burners to
change colour due to the high temperature.

●After switching on the hob, wait a few seconds to
complete the automatic calibration procedure of
the control panel.
●In 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.

The regulation operations listed below are reserved to qualified fitters only. After carrying out any
regulation or pre-regulation operations, any seals must be replaced by the technician. The
regulation of primary air to our burners is not necessary.
9) PROCEDURE FOR REGULATING THE MINIMUM 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 2, 1 and 4 buttons 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 “MIN”. At this point it is
possible to select the burner to be regulated using buttons + and -. After confirmation 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 ⊔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 (7). The word “MIN”
will continue to be present and none of the leds will flash. At this point it is possible to press the Clock
button (7) to exit the procedure, or press buttons + and - 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 fig. 12).
Selecting the type of gas
It is possible to configure the hob to work with methane gas of lpg. To activate the gas selection
procedure, the hob must be working and all the burners must be switched off. Simply press the 2, 1 and 3
buttons for at least 3 seconds. The start of the gas selection procedure is indicated by the switch-off of
the burner level displays and the appearance of “Met” or “Lpg” on the timer display, depending on the
current configuration. It is possible to select the setting required, using buttons 2 and 1. To complete the
procedure the operator must press the Clock button (7).
The activation of this function implicates the cancellation of any switch-off times programmed for the
burners (see fig. 12).
THE BURNERS DO NOT REQUIRE ANY REGULATION OF THE PRIMARY AIR.

REGULATION AND TRANSFORMATION OPERATIONS
Adjusting the minimum capacity of the external ring of the Dual burner will anyway involve lighting the
internal burner ring at its minimum level.

10) REPLACING NOZZLES
The burners can be adapted to suited 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 straight key
“B”, to unscrew the nozzle “A” (see fig. 13) 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 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 2 and 1 buttons with
buttons 7 and 8 continuously for at least 3 seconds. In this condition it is no longer possible to use button
7 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.

MAINTENANCE
Before carrying out any maintenance,
disconnect the appliance from the gas and
electricity supplies.
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. Interference with this device will
eliminate any responsibility by the manufacturer
and invalidate the warranty.
• bserve 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.
• In 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.
11) REPLACING COMPONENTS
To replace the components housed inside the hob
it is necessary to remove the flanges by loosening
the screws (fig. 14), removing the ceramic glass
surface.
After carrying out the operations listed above, it is
possible to replace the solenoids (fig. 15 - 16), the
electrical components and the electronic card
(fig. 17 - 18).
We advise you to change the seal “D” (fig. 16) 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.
