Basic safety instructions

• The manufacturer reserves its right to

make changes in the technical
specifications in order to improve the
appliance quality without any prior
notice. Figures included in this manual
are for schematic purpose only and
may not match exactly with your
appliance. Values stated on the
markings of the appliance or in other
printed documents supplied with the

appliance are obtained under
laboratory conditions as per relevant
standards. These values may vary
according to the usage of the
appliance and ambient conditions.

• This appliance is not intended for use

by persons (including children) with
reduced physical, sensory or mental
capabilities, or lack of experience and
knowledge, unless they have been
given supervision or instruction
concerning use of appliance by a
person responsible for their safety.

Children should be supervised to
ensure that they do not play with the
appliance.

• Do not operate the appliance if it is

defective or shows any visible damage.

• Do not carry out any repairs or

modifications on the appliance.
However, you may remedy some
malfunctions; see
TROUBLESHOOTING, page 17.

• Be careful when using alcoholic drinks

in your dishes. Alcohol evaporates in
high temperatures and may cause fire
since it will catch fire when it gets in
contact with hot surfaces.

• Do not heat closed food containers

and glass jars. Pressure that may
build-up in the jar can cause it to burst.

• Ensure that no flammable materials are

adjacent to the appliance as the sides
become hot during use.

• Do not leave empty pots or pans on

plates that are switched on. They
might get damaged.

• Since it may be hot, do not leave

plastic or aluminum dishes on the

7 | EN

surface of appliance. These kind of
dishes should not be used to keep
food either.

• Check all controls on the appliance are

switched off after use.

Important

Call the authorised service for
installation of the appliance to be
used. After this procedure,
guarantee period will be started.

Safety for children

• Accessible parts of the appliance will

become hot whilst the appliance is in
use and until the appliance has cooled,
children should be kept away.

• Do not store any items above the

appliance that children may reach.

• The packaging materials will be

dangerous for children. Keep the
packaging materials away from
children. Please dispose of all parts of
the packaging according to
environmental standards.

Safety when working with gas

• Any works on gas equipment and

systems may only be carried out by
authorised qualified persons who are
gas safe registered.

• Prior to the installation, be sure that

the conditions of local distribution (gas
type and gas pressure) and the
adjustment of the appliance are
compatible.

• It shall be installed and connected in

accordance with current installation
regulations. Particular attention shall
be given to the relevant requirements
regarding ventilation; See Before
installation, page 9

• The use of a gas-cooking appliance

produces heat and humidity in the
space where it is located. You should
assure a good ventilation of the
kitchen: keep open the natural
ventilation exits, or install a mechanic
ventilation device (hood).

• Gas appliances and systems must be

regularly checked for proper
functioning. Please arrange for annual
maintenance.

• Clean the gas burners regularly. The

flames should be blue and burn evenly.

• Good combustion is required in gas

appliances. In case of incomplete
combustion, carbon monoxide (CO)
might develop. Carbon monoxide is a
colourless, odourless and very toxic
gas, which has lethal effect even in
very small doses.

• Request information about gas

emergency telephone numbers and
safety measures in case of gas smell
from you local gas provider.

fire, immediately cover the pot or
pan with a lid. Switch off the hob if
safe to do so and phone the fire
service.

• Ensure handles of pans cannot

accidentally be caught or knocked and
do not get hot by adjacent heating
zones.

Cooking with gas

• The size of the pan and the size of the

gas flame should match each other.
Adjust the gas flames so that they do
not go beyond the bottom of the pan
always place the pan onto the pan
support in a central position.
