3.3 Using the hob
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 hob 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 cock is open. Return the
knob to and wait at least 60
seconds before lighting it again.

Correct positioning of the pan supports
To install the pan supports, follow the
instructions as shown in the following
figures.
1. Place the lateral pan supports on the
hob, making sure that the front lugs are
facing towards the knobs.
2. Insert the central pan support by slotting
the recesses onto the lugs of the lateral
pan supports.
Also refer to the marking “FRONT”
stamped under the front of each pan
support as an additional aid to positioning
them correctly on the hob.
• Position the pan supports so that the
“FRONT” markings are pointing towards
the knobs of the hob.

EN
Practical tips for using the hob
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 hob or
the counter top during cooking, all pans or
griddles must be placed inside the
perimeter of the hob.
Using a griddle
A few precautions are necessary if you wish
to use a griddle:
• The griddle can be pre-heated with the
burner on maximum power for no more
than 10 minutes.
• Make sure that the burner flame does
not extend beyond the edge of the
griddle.
• Leave a gap of at least 160 mm
between the edge of the griddle and the
side wall.
• Do not place the griddle over more than
one burner at the same time.
• The griddles must not extend beyond the
edge of the hob.
• If one of the burners close to the wooden
rear wall is an ultra-rapid burner (“5”,
“6” or “7+ 8”, see chapter 2.1), leave a
gap of at least 160 mm between that
wall and the edge of the griddle.
• It is not recommended to use
earthenware or steatite (soapstone) pans
to cook or heat food.
• Never use the griddle for more than 40
minutes.
Cookware diameters:
• Auxiliary: 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 and only use specific products 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 surface.
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.
Do not allow residues of sugary foods (such
as jam) to set inside the oven. If left to set for
too long, they might damage the enamel
lining of the oven.
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 hob cool
down.
• Do not use abrasive or corrosive
detergents (e.g. scouring powders, stain
removers and metallic sponges) on
glass parts.
• Do not use rough or abrasive materials
or sharp metal scrapers.
• Do not wash removable parts such as
the hob pan support grids, flame-
spreader crowns and burner caps in the
dishwasher.

Cleaning and maintenance
49
EN
Hob pan support grids
Remove the pan support 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 hob.
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. Replace 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 lukewarm water, then
dried carefully. They can easily be removed
by pulling them upwards.
The continuous contact between
the pan supports 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.
