USE
Precautions
A gas leak can cause an explosion.
If you smell gas or there are faults in the gas
system:
• Immediately turn off the gas supply or
close the valve on the gas cylinder.
• Extinguish all naked flames and
cigarettes.
• Do not turn on power switches or
appliances and do not remove plugs
from power sockets. Do not use phones
or mobile phones inside the building.
• Open the window in order to ventilate
the room.
• Call customer assistance services or
your gas supplier.
Malfunctions
Any of the following indicate a malfunction
and you should contact a service centre.
• The burners do not ignite properly.
• It is difficult to keep the burners lit.
• The burners go out when the appliance
is in use.
• It is difficult to turn the gas cocks.
Practical advice 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.
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.
Use of containers
When cooking, to avoid burns, damage to
the hob or top, all containers or steak pans
must be positioned within the perimeter of
the hob.
Using the accessories
Ring reducers
The ring reducers must be placed on the
hob grids. Make sure they are placed
properly.
See General safety instructions.

UR2 22 - 26 cm
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.
At the end of each use, always
check that the knobs are in position
(off).
CLEANING AND MAINTENANCE - 1191477B920/B
e
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 1 in the flame-spreader crowns
are aligned with the igniters 3 and
thermocouples 2. Also ensure that the
flame-spreader crowns are correctly
engaged in the burner holes.
Precautions when using the griddle
A few precautions are necessary if you wish
to use a griddle:
• The griddle must not extend beyond the
edge of the hob.
• Do not place the griddle over more than
one burner at the same time.
• The griddle can be pre-heated on the
burner at maximum power for no more
than 10 minutes.
• Make sure that the burner flame does
not extend beyond the edge of the
griddle.
• Keep a distance of at least 160 mm
between the griddle and the side and/or
rear wall, especially if it is placed on an
Ultra-Rapid burner.
• Never use the griddle for more than 40
minutes.
CLEANING AND MAINTENANCE
Cleaning the hob
Cooking 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.
Flame-spreader crown 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.
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.
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.
12 - INSTALLATION 91477B920/B
Cleaning the surfaces
To keep the surfaces in good condition, they
should be cleaned regularly after use. Let
them cool first.
Ordinary daily cleaning

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.
What to do if...
The hob does not work:
• Make sure that the hob is connected and
that the main switch is turned on.
• Make sure that there is no power failure.
• Make sure that the fuse has not blown.
In this case replace the fuse.

Safety instructions for positioning and
installation
• Installation can be carried out on various
materials such as masonry, metal, solid
wood or plastic laminated wood as long
as they are heat resistant (>90°C).
• Veneers, adhesives or plastic coatings
on adjacent furniture should be
temperature-resistant (>90°C),
otherwise they might warp over time.
• If the piece of furniture does not have
the required recess opening, either it will
have to be cut or masonry work carried
out by a competent technician.
• The minimum clearance between
exhaust hoods and the cooking surface
must be at least the distance indicated
in the exhaust hood installation
instructions.
• The minimum clearances must also be
respected for the edges of the hob on
the back as indicated in the assembly
instructions.
• If the appliance is to be installed above
an oven, the oven must be fitted with a
cooling fan.

bearing in mind that all the sides of the
internal seal must be flush with the hole.
The values indicated refer to the
cross-section of the internal
conductor.
The aforementioned power cables
are sized taking into account the
coincidence factor (in compliance
with standard EN 60335-2-6).

Mounting
Over built-in oven unit
The clearance between the hob and the
kitchen units or other built-in 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 hob and the top
of the appliance installed below.
On an empty kitchen
If there are other pieces of furniture under
the hob, a double-layer wooden base must
be installed at least 20 mm from the bottom
of the hob to avoid any accidental contact. It
must only be possible to remove the
double-layer base using suitable
equipment.
Fixing to the built-in cabinet
In order to ensure fixing to the built-in
cabinet and optimum centring, the supplied
fixing brackets must be screwed into the
holes in the bottom casing.
Screw the fixing brackets into the dedicated
holes as shown to properly fasten the hob
to the built-in structure.
Instructions for the installer
• If you use a plug to connect to the power
supply, the plug must be accessible after
installation.
