3. ENVIRONMENTAL RESPONSIBILITY
3.1 Our environmental responsibility
Pursuant to Directives 2002/95/EC, 2002/96/EC and 2003/108/EC relating to
the reduction of the use of hazardous substances in electrical and electronic
appliances, as well as to the disposal of refuse, the crossed out bin symbol on
the appliance indicates that the product, at the end of its useful life, must be
collected separately from other refuse. Therefore, the user must consign the
product that has reached the end of its working life to the appropriate selective
collection centres for electrical and electronic refuse, or deliver it back to the
retailer when purchasing an equivalent product, on a one for one basis.
Adequate differentiated collection for the subsequent forwarding of the
decommissioned product to recycling, processing and ecologically compatible
disposal contributes to avoiding possible negative effects on the environment
and on health, and promotes recycling of the appliance's constituent materials.
The illicit disposal of the product by the user results in the application of
administrative sanctions.
The product does not contain substances in quantities sufficient to be
considered hazardous to health and the environment, in accordance with
current European directives.
3.2 Your environmental responsibility
Our product's packaging is made of non-polluting materials, therefore
compatible with the environment and recyclable. Please help by disposing of the
packaging correctly. You can obtain the addresses of collection, recycling and
disposal centres from your retailer or from the competent local organisations.
Do not discard the packaging or any part of it, or leave it unattended. It can
constitute a suffocation hazard for children, especially the plastic bags.
Your old appliance also needs to be disposed of correctly.
Important: hand over your appliance to the local agency authorised for the
collection of household appliances no longer in use. Correct disposal enables
intelligent recovery of valuable materials.
Before disposing of your appliance it is important to remove doors and leave
shelves in the same position as for use, to ensure that children cannot
accidentally become trapped inside during play. It is also necessary to cut the
connecting cable to the power supply, removing it along with the plug.

If the burners should go out accidentally, after about 20 seconds a safety device
will be tripped, cutting off the gas supply, even if the gas tap is open.
5.3 Practical tips for using the burners
For better burner performance and minimum gas
consumption, pans with flat, even bases and with lids should
be used, and their size should be in proportion to the burner
(see “5.4 Pan diameters”).
During cooking, in order to avoid burns or damage to the hob
top, all pans or griddles must be positioned inside the outer
edge of the hob and at a minimum distance of 5-7 cm must be
maintained from the knobs.
If the burner flame accidentally goes out, turn off the control
knob and wait at least 1 minute before trying to re-light the
burner.

9. GAS CONNECTION
If the appliance is installed on an oven, you must avoid running the gas tube
round the back of the oven in order to avoid overheating.
Connection to the gas supply network can be made using a rigid copper hose or
a flexible steel hose with a continuous wall and in compliance with the
guidelines established by the applicable standard. To facilitate the connection,
connector Aon the back of the appliance can be orientated laterally; loosen
hexagonal nut B, twist connector Ainto the desired position then retighten
hexagonal nut B(it is sealed with a rubber gasket). Once the operation is
complete, check the hose fittings for leaks using a soapy solution; never use a
flame. The hob is preset for natural gas G20 (2H) at a pressure of 20 mbar. To
set it up for supply using other types of gas, see Chapter “10. ADAPTATION TO
DIFFERENT TYPES OF GAS”. The gas inlet connection is threaded ½” for
external gas (ISO 228-1).
Connection with a rigid copper hose: The
connection to the gas supply network must be made
in such a way that it does not cause stresses of any
type on the appliance. The connection can be made
using the adapter unit D with double cone, always
inserting gasket C(provided) in between.
Connection with a flexible steel hose: use only
continuous wall stainless steel hoses that comply
with the applicable standards, making sure to always
insert gasket C (provided) between connector A and
flexible hose B.
Installation with flexible hose must be carried out so that the length of the piping
does not exceed 2 metres when fully extended; make sure that the hoses do not
come into contact with moving parts and that they are not crushed in any way.

Use a pressure regulator and make the connection on the gas cylinder following
the guidelines set out in the regulations in force.
Make sure that the supply pressure complies with the values indicated in the
paragraph “10.3 Burner and nozzle characteristics tables”.
9.2 Room ventilation
The room containing the appliance should have an air supply in accordance with
the standards in force. The room where the appliance is installed must have
enough air flow needed for the regular combustion of gas and the necessary air
change in the room itself. The air vents, protected by grills, must be the right
size to comply with current regulations and positioned so that no part of them is
obstructed, not even partially.
The room must be kept adequately ventilated in order to eliminate the heat and
humidity produced by cooking: in particular, after prolonged use, you are
recommended to open a window or to increase the speed of any fans.
9.3 Extraction of the combustion products
The combustion products may be extracted by means of hoods connected to a
natural draught chimney whose efficiency is certain or via forced extraction. An
efficient extraction system requires precision planning by a specialist qualified in
this area and must comply with the positions and distances indicated by the
regulations. When the job is complete, the installer must issue a certificate of
conformity.
