burners or hob body.
• Cooking vessels or griddle plates
should be placed inside the perimeter of
the cooktop.
• All pans must have smooth, flat bottoms.
• If any liquid does boil over or spill,
remove the excess from the cooktop.

EN
• Burners not igniting properly.
• Burners failing to remain alight.
• Burners extinguishing whilst in operation.
• Gas valves with are difficult to turn.
In case the appliance fails to operate
correctly, contact the Authorised Assistance
Centre in your area.
3.2 First use
1. Remove any protective film from the
outside or inside of the appliance,
including accessories.
2. Remove any labels (apart from the
technical data plate) from accessories.
3. Remove and wash all the appliance's
accessories (see 4 Cleaning and
maintenance).
3.3 Using the cooktop
All the appliance’s control and monitoring
devices are located together on the front
panel. The burner controlled by each knob
is shown next to the knob. The appliance is
equipped with an electronic ignition device.
Simply press the knob and turn it anti-
clockwise to the maximum flame symbol,
until the burner ignites. If the burner does not
light in the first 15 seconds, turn the knob to
and wait 60 seconds before trying
again. After lighting, keep the knob pressed
in for a few seconds to allow the
thermocouple to heat up. The burner may
go out when the knob is released: In this
case, the thermocouple has not heated up
sufficiently.
Wait a few moments and repeat the
operation. Keep the knob pressed in
longer.
Correct positioning of the flame-
spreader crowns and burner caps
Before lighting the cooktop burners, make
sure that the flame-spreader crowns are
correctly positioned in their housings with
their respective burner caps. Make sure that
the holes in the burners are aligned with the
igniters and thermocouples. Also ensure that
the flame-spreader crowns are correctly
engaged in the burner holes.
In case of an accidental switching
off, a safety device will be tripped,
cutting off the gas supply, even if
the gas tap is open. Return the
knob to and wait at least
60 seconds before lighting it
again.

Use
14
Correct positioning of the grids
To install the grids follow the instructions and
the following figures.
1. Lay the lateral grids on the cooktop
paying attention to position the front teeth
facing the knobs.
2. Lay the centre grid engaging the notches
in the teeth of the lateral grids.
In addition, pay attention to the mark
"FRONT" under each grid at the front, as a
further help to correctly position the grids on
the cooktop.
• Position the grids so that the marks
"FRONT" are facing the cooktop knobs.

EN
Practical tips for using the cooktop
For better burner efficiency and to minimise
gas consumption, use pans with lids and of
suitable size for the burner, so that the
flames do not reach up the sides of the pan.
Once the contents come to the boil, turn
down the flame far enough to ensure that
the liquid does not boil over.
To prevent burns or damage to the cooktop
or the counter top during cooking, all pans
or griddles must be placed inside the
perimeter of the grids.
Cookware diameters:
• Aux.: 12 - 18 cm.
• Semi rapid: 14 - 24 cm.
• Rapid: 20 - 26 cm.
• Ultra-rapid: 20 - 30 cm.

Cleaning and maintenance

4 Cleaning and maintenance
4.1 Instructions
4.2 Cleaning the appliance
To keep the surfaces in good condition,
they should be cleaned regularly after use.
Let them cool first.
Ordinary daily cleaning
Always use specific products only that do
not contain abrasives or chlorine-based
acids.
Pour the product onto a damp cloth and
wipe the surface, rinse thoroughly and dry
with a soft cloth or a microfibre cloth.
Food stains or residues
Do not use steel sponges and sharp
scrapers, as they will damage the surfaces.
Use normal, non-abrasive products and a
wooden or plastic tool, if necessary. Rinse
thoroughly and dry with a soft cloth or a
microfibre cloth.
Improper use
Risk of damage to surfaces
• Do not use steam jets to clean the
appliance.
• Do not use cleaning products containing
chlorine, ammonia or bleach on parts
made of steel or that have metallic
surface finishes (e.g. anodizing, nickel-
or chromium-plating).
• If it comes into contact with aggressive
detergents, hard water or spills (cooking
water, sauces, coffee, etc.), clean
immediately after having let the cooktop
cool down.
• Do not use rough or abrasive materials
or sharp metal scrapers.
• Do not wash the removable
components such as the cooktop grids,
flame-spreader crowns and burner caps
in a dishwasher.
Annual service by an authorised
person is recommended, or if any
of the following conditions are
noticed; incomplete ignition,
appreciable yellow tipping,
carbon deposition, lifting, floating,
lighting back or objectionable
odour.

Cleaning and maintenance
17
EN
Cooktop grids
Remove the grids and clean them in
lukewarm water and non-abrasive
detergent. Make sure to remove any
encrustations. Dry them thoroughly and
return them to the cooktop.
Igniters and thermocouples
For correct operation the igniters and
thermocouples must always be perfectly
clean. Check them frequently and clean
them with a damp cloth if necessary.
Remove any dry residues with a wooden
toothpick or a needle.
Flame-spreader crowns and burner caps
For easier cleaning, the flame-spreader
crowns and the burner caps can be
removed.
Wash them in hot water and non-abrasive
detergent. Carefully remove any
encrustation, then wait until they are
perfectly dry. Refit the flame-spreader
crowns making sure that they are correctly
positioned in their housings with their
respective burner caps.
Knobs
The knobs should be cleaned with a soft
cloth dampened with warm water, then
dried carefully. They can easily be removed
by pulling them upwards.
The continuous contact between
the grids and the flame can cause
modifications to the enamel over
time in those parts exposed to
heat. This is a completely natural
phenomenon which has no effect
on the operation of this
component. Do not use aggressive products
containing alcohol or products for
cleaning steel and glass when
cleaning the knobs, as these
products could cause permanent
damage.

Over built-in oven unit
The clearance between the cooktop and
the kitchen furniture or other installed
appliances must be enough to ensure
sufficient ventilation and air discharge.
If installed above an oven, a space must be
left between the bottom of the cooktop and
the top of the appliance installed below.

Over empty kitchen unit or drawers
If there are other pieces of furniture (lateral
walls, drawers, etc.), dishwashers or fridges
under the cooktop, a double-layer wooden
base must be installed at least 10 mm from
the bottom of the cooktop to avoid any
accidental contact. It must only be possible
to remove the double-layer base using
suitable equipment.

wooden base exposes the user to
possible accidental contact with
sharp or hot parts.

Cooktop seal
To prevent leakage of liquid between the
frame of the cooktop and the work surface,
put the insulating seal provided in position
before assembly.
1. Apply the seal provided along the outer
edge of the appliance surface.
2. Lay the appliance in the hole on the work
top (chapter 5.2 “Section cut from the
work surface”).
5.5 Fixing using brackets
The figures below show the exact holes to
be used to correctly attach the cooktop to
the work surface with brackets.
60 cm models
70 cm models with central UR
Do not use silicone to secure the
cooktop. This would make it
impossible to remove, if necessary,
without damaging it. Use the
insulating seal provided.
