The manufacturer will not be liable for any damage to persons or
property caused by non-observance of the above instructions or deriving
from the tampering of even a single part of the hob.
2.4 Ventilation of rooms
The hob may be installed only in rooms with permanent ventilation, as
required by standards regulations in force. The room in which the hob is
installed must have sufficient air flow to satisfy the requirements of
normal gas combustion and of necessary air exchange in the room. The
air intakes, protected by screens, must be appropriately sized
(regulations in force) and placed so as not to be blocked in any way.
The room where the oven is installed should be suitably ventilated to
avoid overheating or excess humidity produced by cooking, and in the
case of lengthy use a window should be opened or the speed of any
ventilators should be increased.

Instructions for the installer
22
2.5 Discharge of combustion products
Discharge of combustion products must be guaranteed by means of
hoods connected to a natural draught flue with certain efficiency, or by
means of forced aspiration. An efficient aspiration system requires
careful planning by a specialist capable of installing it, respecting the
positions and distances prescribed by standards. After installation, the
installer must issue a certificate of conformity.
2.6 Gas connection
Connection to the gas mains may be made with a rigid copper pipe or
with a flexible pipe and conforming to the provisions defined by standard
regulations in force.
Use a soapy solution to check for proper tightness. Never use a free
flame.
The hob has been inspected for G20 (2H) natural gas at a pressure of
20 mbar. For use with other types of gases, see Section “3. ADAPTING
TO DIFFERENT TYPES OF GAS”. The gas intake fitting is ½” gas
external threaded (ISO 228-1).
Connection with rigid copper pipe:
the connection to the gas mains must
not provoke stress of any kind on the
hob.
Connection may be made by using
biconical adapter Dwith insertion of
gasket C(supplied).
Connection with flexible pipe: use
only flexible pipes conforming to
standard regulations in force, inserting
gasket C(supplied) between fitting A
and flexible pipe E.
The flexible pipe has to be installed so that pipe length does not exceed
1.5 meters of maximum extension. Make sure that the pipes do not touch
any moving parts or become damaged.
2.7 Connection to LPG
Use a pressure regulator and make the connection to the tank according
to the provisions of standards regulations in force. Make sure that feed
pressure conforms to the levels shown in the table in paragraph “3.2
Burner and nozzle characteristics table”.

3. ADAPTATION TO DIFFERENT TYPES OF GAS
Before performing any cleaning or maintenance work, detach th
e
appliance from the electrical socket.
The cooker hob is set for natural gas G20 (2H) at a pressure of 20 mba
r
for cookers with maxi oven, and for LPG G30/G31 (3+) at a pressure of
28/37 mbar for cookers with gas-bottle compartments. In the case of
functioning with other types of gas the burner nozzles must be changed
and the minimum flame adjusted on the gas taps. To change the
nozzles, proceed as described below.
3.1 Replacement of nozzles on the hob
This operation requires no primary air regulation.
1. Extract the grids and remove all the caps and flame-spreade
r
crowns;
2. unscrewtheburnernozzleswitha7mmsocketwrench;
3. replace the nozzles according to the type of gas to be used and the
description in paragraph “3.2 Burner and nozzle characteristics
table”.

4. FINAL OPERATIONS
Having carried out the above adjustments, reassemble the appliance
following, backwards, the instructions in paragraph “3.2 Burner and
nozzle characteristics table”.
After adjustment to a different kind of gas from the one for which the
cooker has been tested, replace the plate inside the heating
compartment with one corresponding to the new kind of gas. This plate
can be obtained from your nearest Authorised Assistance Centre.
4.1 Adjustment of minimum for natural gas
Light the burner and take it to the minimum.
Remove the gas tap knob and turn the
adjustment screw inside or at the side of the tap
shaft (depending on the model) until there is a
regular minimum flame. Replace the knob and
check burner flame stability: (rapidly turning the
knob from maximum to minimum position, the
flame should not go out). Repeat the operation on
all the gas taps.
4.2 Regulation of minimum for LPG
To regulate the minimum for LPG, completely tighten (clockwise) the
screw inside or next to the gas tap pin (depending on the model).
The diameters of the by-passes for each burner are given in table “3.2
Burner and nozzle characteristics table”.
4.3 Lubrication of gas taps
With time it may happen that the gas taps get blocked and hard to turn.
Clean them inside and re-grease them. This operation must be done
by a specialised technician.

5. USE OF THE COOKING HOB
5.1 Lighting the burners
Before lighting the hob burners check that the flame caps are in th
e
correct position and that their burner caps are in place, making sure tha
t
the holes Ain the flame caps correspond to the spark plugs an
d
thermocouples.
The optional grid Bis for use with “woks” (Chinese pans).
To prevent deterioration of the hob we have equipped the cooker with
a
raised pan stand Cto be placed underneath pans more than 26 cm i
n
diameter.
The supplied reduction rest Cis also used for small pans.
Each knob corresponds to the burner indicated. The
appliance is equipped with an electric lighting device.
To light the burners, press and turn the knob
anticlockwisetothelargeflamesymbol . Keep the
knob pressed for about 2 seconds to let the
thermocouple heat up.
If the burner turns off when the knob is released, it means that the
thermocouple isn’t hot enough. Repeat ignition and keep the knob
pressed longer.
Once the burner has been ignited, the flame can be regulated as
required.
Always check that the control knobs are in the position (off) when you
finish using the hob.
If the burners turn off accidentally, a safety device will trip after about 20
seconds to cut off gas flow (even with the gas tap open).

Instructions for the user
27
5.2 Practical advice for using the burners
For better use of the burners and lower gas consumption, use covered
containers that are proportional in size to the burner to prevent the flame
from licking the sides (see paragraph “5.3 Diameter of containers”).
When water reaches the boiling point, lower the flame so that it doesn’t
overflow.
To avoid burns or damage to the hob, all recipients or griddle plates
must be placed within the perimeter of the cooking hob.
When using fats or oils, be extremely careful that they don’t overheat
and catch fire.

6. CLEANING AND MAINTENANCE
Before any intervention, disconnect the power supply of the device.
6.1 Cleaning stainless steel
To keep stainless steel in good condition it should be cleaned regularly
after use. Let it cool first.
6.1.1 Ordinary Daily Cleaning
To clean and preserve the stainless steel surfaces, always use only
specific products that do not contain abrasives or chlorine-based acids.
How to use: pour the product on a damp cloth and wipe the surface,
rinse thoroughly and dry with a soft cloth or deerskin.
6.1.2 Food stains or residues
Do not use metallic sponges or sharp scrapers: they will
damage the surface.
Use normal non-abrasive products for steel, and a wooden or
plastic tool if necessary.
Rinse thoroughly and dry with a soft cloth or deerskin.
6.2 Cleaning of cooking hob components
Grids, caps, flame cap crowns and burners can be
removed for ease of cleaning. Wash them in warm
water using a non-abrasive detergent, taking care to
remove all tough spots. Before remounting, allow the
components to fully dry out. Re-install the caps on
the corresponding crowns making sure that niches A
are perfectly aligned with pins Bof the burners.
To work well, the ignition plugs and thermocouples must
always be very clean. Check them frequently and clean
them with a wet rag if necessary. Any dry residue should be
removed with a toothpick or a needle.
