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 anticlockwise 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 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.
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.
Correct positioning of the grids
The grids over the burners must be
positioned in parallel to the control panel,
not perpendicular.
Correct positioning of the flamespreader 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.
32
Use
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 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.
Cookware diameters:
• Auxiliary: 7 - 18 cm.
• Semi-rapid: 10 - 24 cm.
• Reduced rapid: 18 - 24 cm.
• Medium rapid: 20 - 26 cm.
• Large rapid: 20 - 26 cm.
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.
Limitations on griddle use
EN
Improper use
Risk of damage to surfaces
• Do not use cast-iron griddles.
A few precautions are necessary if you wish
to use a griddle:
• Use aluminium griddles, including those
with anti-stick coating, with dimensions
not to exceed 35 x 26 cm;
• 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 the
foodstuffs on the griddle to cook them;
do not exceed 40 minutes of total use for
the griddle.
• Do not allow the burner flames to extend
beyond the edge of the griddle;
• Leave a gap of at least 150 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.

Cleaning and maintenance
4 Cleaning and maintenance
4.1 Instructions
Improper use
Risk of damage to surfaces
• Do not use steam jets for cleaning 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 abrasive or corrosive
detergents on glass parts (e.g. powder
products, stain removers and metallic
sponges).
• Do not use rough or abrasive materials
or sharp metal scrapers.
• Do not wash the removable
components such as the hob pan stands,
flame-spreader crowns and burner caps
in a dishwasher.
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 microfibre 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 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.
4.2 Cleaning the appliance
To keep the surfaces in good condition,
they should be cleaned regularly after use.
Let them cool first.
34
Cleaning and maintenance
Cooking hob grids
Remove the grids and clean them with
lukewarm water and non-abrasive
detergent. Make sure to remove any
encrustations. Dry them thoroughly and
return them to the hob.
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.
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 nonabrasive 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.
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.
