technical data plate) from the
accessories and from the appliance
body.
High temperature
Danger of burns
• Make sure that the flame-spreader
crowns are correctly positioned in their
seats with their respective burner caps.
• Oils and fats could catch fire if
overheated. Be very careful.
• Do not leave the appliance unattended
during cooking operations where fats or
oils could be released.
• Do not spray any spray product near the
appliance.
• Do not touch the appliance’s burners
when it is running. Leave them to cool
before cleaning.
• Keep children under the age of 8 away
from the appliance when it is in use.
Improper use
Risk of damage to surfaces
• Do not use aluminium foil to cover the
burners or hob body.
• Make sure that the flame-spreader
crowns are correctly positioned in their
seats with their respective burner caps.
• Cooking vessels or griddle plates
should be placed inside the perimeter of
the hob.
• All pans must have smooth, flat bottoms.
• If any liquid does boil over or spill,
remove the excess from the hob.

3. Remove and wash all the appliance
accessories (see 3 Cleaning and
maintenance).
2.2 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 counter-
clockwise to the maximum flame symbol,
until the burner lights. If the burner does not
light in the first 15 seconds, turn the knob to
and wait 5 minutes 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.
Setting flame size
A minimum and maximum flame size can be
set for each burner.
Rapid burner
Dual Flame burner
WARNING
FIRE HAZARD
• For your safety: do not allow the burner
flame to extend beyond the edge of the
pan.
• Turn off all controls when the appliance
is not in use.
In case of an accidental turning 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
5 minutes before lighting it again.
When the outer ring is lit,
regardless of the size of the flame,
the inner ring is also lit. It is not
possible to switch on the outer ring
without the inner one.

Simmer function
1. Switch on the Dual Flame burner internal
ring.
2. Set the flame to the minimum.
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 seats with their
respective burner caps. Make sure that the
holes 1of the flame-spreader crowns are
aligned with the thermocouples 2and
igniters 3.
Correct positioning of the grates
For 36” models first position the right and
left side grates (1) and then the central one
(2). For 30” models the positioning order is
not relevant.
Practical tips for using the hob
For better burner efficiency and to minimize
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.
In case of power failure
In the event of a power failure, the burners
may be lit witha match. Press the control
knob for the selected burner and turn it
counterclockwise to the highest power
setting. Carefully hold a lit lighter or match
against the burner.
This function is extremely useful for
melting food like butter, chocolate
or similar and for simmering small
quantities of food.
If the external cup switches on at
full power, set half power at least
for the internal cup.

Cookware
Ideally, cookware should have a flat
bottom, straight sides, a tight-fitting lid and
medium-to-heavy thickness.
Rough cookware finishes may scratch the
appliance. Aluminum and copper may be
used in cookware as a core material or
base. However, when used as a base they
can leave permanent marks on the
appliance or grates.
Cookware properties are a factor in how
quickly and evenly heat is distributed, which
affects cooking results. A non-stick finish has
the same characteristics as its base material.
For example, a non- stick finish on aluminum
cookware will take on the properties of
aluminum.
Refer to the following chart as a guide to
the physical properties of cookware.
Aluminum
• Heats quickly and evenly.
• Suitable for all types of cooking.
• Medium or heavy thickness is best for
most cooking tasks.
Cast iron
• Heats slowly and evenly.
• Good for browning and frying.
• Maintains heat for slow cooking.
Ceramic or glass-ceramic
• Follow the manufacturer’s instructions.
• Heats slowly but unevenly.
• Best results with low to medium heat
settings.
Copper
• Heats very quickly and evenly.
Earthenware
• Follow the manufacturer’s instructions.
• Use low heat settings.
Porcelain enameled steel or cast iron
• See stainless steel or cast iron.
Stainless steel
• Heats quickly but unevenly.
• Stainless steel cookware with aluminum
or copper as a core material or bottom
provides even heating.

3 Cleaning and maintenance
3.1 Instructions
Recommendations
To keep the surfaces in good condition,
they should be cleaned regularly after use.
Let them cool first.
Ordinary daily cleaning
Always use only 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 microfiber cloth.
Food stains or residues
Do not use metallic sponges or sharp
scrapers as they will damage the surfaces.
Use ordinary non-abrasive products with
the aid of wooden or plastic utensils if
necessary. Rinse thoroughly and dry with a
soft cloth or a microfiber cloth.
Cooktop grates
Remove the grates and clean them with
lukewarm water and non-abrasive
detergent. Make sure to remove any
encrustations. Dry them thoroughly and
return them to the cooktop.
3.2 Cleaning the hob
1. Pour some non-abrasive detergent on a
damp cloth and wipe the surfaces.
2. Rinse thoroughly.
3. Dry with a soft cloth or a microfiber cloth.
Cleaning cooktop grates, flame-
spreader crowns and burner caps
1. Remove the components from the hob.
2. Clean with lukewarm water and non-
abrasive detergent. Make sure to
remove any encrustations.
WARNING
ELECTRICAL SHOCK HAZARD
• Before servicing, disconnect the
appliance from the power supply.
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 steel
parts or parts with metallic finishes on
the surface (e.g. anodizing, nickel- or
chromium-plating).
• Do not use rough or abrasive materials
or sharp metal scrapers.
• Do not wash the removable
components such as the hob pan
stands, flame spreaders and burner
caps in a dishwasher.
• Keeping appliance area clear and free
from combustible materials, gasoline
and other flammable vapors and
liquids.
• Not obstructing the flow of combustion
and ventilation air.
We recommend the use of
cleaning products distributed by
the manufacturer.

3. Dry thoroughly with a soft cloth or a
microfiber cloth.
4. Replace the components on the hob.
Flame spreaders and burner caps
For easier cleaning, the flame spreaders
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 spreaders
making sure that they are correctly
positioned in their housings with their
respective burner caps.
Visually checking pilot(s) and burner flames.
Cleaning the igniters and thermocouples
• If necessary, clean the igniters and
thermocouples with a damp cloth.
• If there is any dry residue, remove it with
a toothpick or needle.
Continuous contact between the
grates 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.
