EN
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 notches of the flame-spreader
crowns (A) are positioned in their
corresponding housings (B) with their
respective burner caps. Make sure that the
holes in the burner (C) are aligned with the
igniters and thermocouples (D). 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 trivets
There are concave silicone rests with a hole
underneath the trivets that must be
positioned on the relative fixing pins on the
cooktop.
Make sure that the trivets are simply centred
on their respective burners, without forcing
the burners to be raised or tilted. If they are,
repeat the positioning procedure.
If you find that a pan is particularly unstable,
make sure that the trivets have been
positioned correctly.
Installing the trivets
The trivets are provided unassembled on
the cooktop. To position each trivet
correctly on its burner, follow the instructions
as shown in the figure.
Each trivet must be positioned on the
corresponding burner in order to ensure
that it works correctly.
Be very careful to match the
different central diameters of the
trivets to the flame-spreader
crowns.

EN
Practical tips for using the cooktop
For better burner efficiency and to minimise
gas consumption, use lidded pans of
suitable size for the burner, so that flames
do not reach up the sides of the pan. Once
the contents come to the boil, turn down the
flame enough to ensure that the liquid does
not boil over.
During cooking, in order to avoid burns,
damage to the cooktop or countertop, all
pans or griddles must be positioned inside
the outer edge of the cooktop and at a
minimum distance of 50 mm from the knobs.
Using a griddle
A few precautions are necessary if you wish
to use a griddle:
• Griddles must not protrude beyond the
perimeter of the cooktop
• Aluminium griddles with Teflon anti-stick
coating should be pre-heated for a
maximum of 5 minutes in order to avoid
damage to the appliance and the Teflon
coating. After pre-heating, place food
on the griddle to cook; do not exceed
40 minutes of griddle use
• Do not use griddles or plates to cook or
heat food on the ultra-rapid burner (UR).
• If one of the burners close to the wooden
rear wall is an ultra-rapid (UR) burner,
leave a gap of at least 160 mm between
the wall and the edge of the griddle
• It is not recommended to use
earthenware or steatite pans to cook or
heat food.
• Do not allow the burner flames to 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
• Never use the griddle for more than 40
minutes.
Cookware diameters:
• AUX: 7 - 18 cm.
• SR: 10 - 24 cm.
• R: 18 - 24 cm.
• UR3: 24 - 28 cm.

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.
Cooktop trivets
Remove the trivets 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.
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 trivets,
flame-spreader crowns and burner caps
in a dishwasher.
The continuous contact between
the trivets 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.

Cleaning and maintenance
17
EN
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.
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.
