Features
NOTE:
✓The appliance may be provided with:
• a gas-lighter incorporated in the knobs ( symbol beside big flame -
maximum aperture or max gas flow)
• no gas-lighter (no symbol beside the knob)
• safety valve system.
✓If the appliance has a safety valve system fitted (beside every burner is a T-shaped probe,
as in Fig. 7 - not to be confused with the S-shaped electrode of the gas lighter), the flow
of gas will be stopped if and when the flame should accidentally go out.

7
GAS BURNERS
Gas flow to the burners is adjusted by turning the knob illustrated in figs. 3a - 3b which
control the valves.
Turning the knob so that the indicator line points to the symbols printed on the panel
achieves the following functions:
✓full circle ●= closed valve
✓symbol – = maximum aperture or flow
✓symbol = minimum aperture or flow
The maximum aperture position permits rapid boiling of liquids, whereas the minimum
aperture position allows slower warming of food or maintaining boiling conditions of
liquids.
To reduce the gas flow to minimum, rotate the knob further anti-clockwise to point
the indicator towards the small flame symbol.
Other intermediate operating adjustments can be achieved by positioning the indicator
between the maximum and minimum aperture positions, not between the maximum
aperture and closed positions.
Use of the Hob
N.B. When the hob is not being used, set the gas knobs to their closed posi-
tions and also close the cock valve on the gas bottle or the main gas supply
line.

LIGHTING THE BURNERS
Models without safety cut-off valves
In order to light the burner, you must:
Models without electric ignition:
1 – To light one of the gas burners, hold a flame (e.g. a match) close to the top
part of the burner, push in and turn the relative knob (fig. 3b) in an anti-
clockwise direction (fig. 4), pointing the knob indicator towards the large flame
symbol (i.e. max. gas flow).
2 – Adjust the burner according to the power required.
3 – To turn it off, turn the knob towards the right, up to the safety click.
Models with electric ignition incorporated into the knobs:
1 – Lightly press the knob fig. 3b in anti-clockwise direction (fig. 4) up to the maxi-
mum aperture (symbol ), push in and hold the knob; this will light the gas.
In the case of a mains failure light the burner with a match or lighted taper.
2 – Adjust the burner according to the power required.
3 – To turn it off, turn the knob towards the right, up to the safety click.
N.B. If your local gas supply makes
it difficult to light the burner with
the knob set to maximum, set the
knob to minimum and repeat the
operation.

LIGHTING THE BURNERS
Models fitted with safety cut-off valves
In order to light the burner, you must:
Models without electric ignition:
1 – To light one of the gas burners, hold a flame (e.g. a match) close to the top
part of the burner, push in and turn the relative knob (fig. 3a) in an anti-
clockwise direction (fig. 4), pointing the knob indicator towards the large flame
symbol (i.e. max. gas flow).
2 – Wait about ten seconds after the gas lighting before releasing the knob
(starting time for the valve).
3 – Adjust the gas valve to the desired power.
Models fitted with electric ignition incorporated into the knobs:
1 – Press in the corresponding knob and turn counter-clockwise (fig. 4) to the full
flame position marked by the symbol (fig. 3a) and hold the knob in until
the flame has been lit.
In the case of a mains failure light the burner with a match or lighted taper.
2 – Wait about ten seconds after the gas lighting before releasing the knob (starting
time for the valve).
3 – Adjust the gas valve to the desired power.
MODELS FITTED WITH SAFETY CUT-OFF VALVES
Important
If the burner flame should go out for some reason, the safety valve will automatically
stop the gas flow.
To re-light the burner, return the knob to the closed ●position, wait for at least 1
minute and then repeat the lighting procedure.
If your local gas supply makes it difficult to light the burner with the knob set to maxi-
mum, set the knob to minimum and repeat the operation.

CHOICE OF BURNER
The symbols printed on the panel by the side of the knob indicate which burner you
are controlling.
Choose a suitable burner depending on the cookware diameter and capacity.
The pan diameter should be suitable for the burner power to make the most of the
burner's high efficiency and not waste fuel.
A small pan does not boil more quickly on a large burner (fig. 5).
Attention: During use the hob becomes very hot under the cooking zones.
Keep children away.

CORRECT USE OF TRIPLE-RING BURNER
✓The flat-bottomed pans are to be placed directly onto the pan-support.
✓To use the WOK you need to place the proper stand (supplied with some models
only) in order to avoid any faulty operation of the triple-ring burner (Fig. 6a).
IMPORTANT:
The special grille for wok pans (supplied with some models only) (fig. 6b) MUST BE
PLACED ONLY over the pan-rest for the triple-ring burner.

GENERAL TIPS
✓Before cleaning the hob switch it off and wait for it to cool down.
✓Clean with a cloth, hot water and soap or liquid detergent.
✓Do not use products which are abrasive, corrosive or chlorine based.
✓Do not use steel pads.
✓Do not leave acid or alkaline substances (vinegar, salt, lemon juice, etc.) on the
hob.
✓Do not use steam jet cleaners because the humidity could infiltrate into
the appliance making it dangerous.
✓WARNING: When correctly installed, your product meets all safety requirements
laid down for this type of product category. However special care should be taken
around the underneath of the appliance as this area is not designed or intended
to be touched and may contain sharp or rough edges, that may cause injury.
ENAMELLED PARTS
✓All the enamelled parts must be washed only with a sponge with soapy water or
other non-abrasive products.
✓Dry preferably with a soft cloth.
✓If acid substances such as lemon juice, tomato conserve, vinegar etc. are left on
the enamel for a long time they will etch it, making it opaque.
STAINLESS STEEL SURFACES
✓Stainless steel parts should be rinsed with water and dried with a microfibre or
soft cloth.
✓For persistent dirt, use specific non-abrasive products available commercially or a
little hot vinegar.
✓Note: regular use will cause discolouring around the burners, because of the high
flame temperature.
Cleaning and Maintenance

BURNERS AND GRIDS
✓These parts can be removed and cleaned with appropriate products.
✓After cleaning, the burners and their flame spreaders must be well dried and correct-
ly replaced.
✓It is very important to check that the burner flame spreader and the cap have been
correctly positioned. Failure to do so can cause serious problems.
✓In appliances with electric ignition, check that the electrode “S” (fig. 7) is always
clean to ensure trouble-free sparking.
✓In the models with safety device, check that the probe “T” (fig. 7) next to each burn-
er is always clean to ensure correct operation of the safety valves.
✓Both the probe and ignition plug must be very carefully cleaned.
✓Note: To avoid damage to the electric ignition do not use it when the
burners are not in place.
GAS TAPS
✓Regular lubrication of the gas taps must only be performed by specialised engineers.
✓If the gas taps are not working properly call the After-Sales Service.
CONTROL KNOBS
✓The control knobs may be removed for cleaning but care should be taken not to
damage the seal.
