4.2 Ventilation of rooms
Caution – This hob may only be installed and operated in rooms

permanently ventilated in accordance with current regulations. For
proper operation of a gas appliance it is essential for the air necessary
for combustion of the gas to be able to flow naturally into the room. Air
must flow directly into the room through openings in its outside walls.
This (these) opening (s) must have a free passage cross-section of at
least 100 cm2or 200 cm2 for appliances not equipped with gas safety
device. These openings must be constructed so that they cannot be
obstructed indoors or outdoors, and should preferably be close to the
floor on the side opposite to the combustion gas discharge point. If it is
not possible to make the openings in the room where the cooker is
installed, the necessary air may be taken from an adjoining room,
proveded it is not a bedroom or a room with fire risk.

4.3 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.

7. Using the hob

Before turning on the burners, make sure that the burner rings,
caps and grids have been fitted correctly.
In the wok burner, notch A must be aligned with pin B.
Grid C provided is intended for use with woks (Chinese pans).
Adapter D comes only with open grids models and is intended
for use with small sized vessels.

7.1 Ignition of the burners

The device is fit with electronic ignition. Simply press and simultaneously
turn the knob counter-clockwise on the low point flame symbol, until the
burner is ignited. In models with safety valve, the knob has to be turned
to the ignition symbol before it is pressed, and after ignition the knob
has to be kept pressed for about 2 seconds to keep the flame lit and to
activate the safety device.
The burner might go off when the knob is released. In this case repeat the
aforesaid operation keeping the knob pressed for more than 2 seconds.

Should the burners go off accidentally in the models with valves,
a safety device will trip after approximately 20 seconds to block
the gas outlet even if the cock is open.

7.2 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 “7.3
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 hob, at a distance of 3-4 cm
from the knobs. All containers have to have a flat and smooth
bottom. When using fats or oils, be extremely careful that they don’t
overheat and catch fire. If the flame accidentally goes out, turn off the
control knob and wait at least 1 minute before trying to re-light the burner.

7.4 Using a griddle plate

A few precautions are necessary if you wish to use a griddle plate:

• leave a gap of at least 160 mm between the edge of the griddle

plate and the side wall;

• if one of the burners close to the wooden rear wall is of triple flame

type, leave a gap of at least 160 mm between this wall and the
edge of the griddle plate;

• do not allow the burner flames to extend beyond the edge of the

griddle plate;

• operate the burners underneath the griddle plate for 10 minutes at

maximum power, then turn them down to the minimum setting.
Never use the griddle plate for more than 45 minutes.

8. Cleaning and maintenance

Never use a steam jet to clean the appliance.

Before any intervention, disconnect the power supply of the device.

8.1 Cleaning

Clean the cooking top regularly every time you use it, obviously
after it has cooled.

8.1.1 Regular daily cleaning of the hob

In order to clean and preserve the surface, always use specific
products only, which do not contain abrasive substances or
chlorine-based acid substances.
How to use: pour the product on a damp cloth and wipe the
surface, rinse thoroughly and dry with a soft cloth or deerskin.

8.1.2 Food stains or residues

Do not use metallic sponges or sharp scrapers: they will
damage the surface.
Use normal non-abrasive products and remove spots or
residuals with non-scratch sponges or, if need be, with
wood or plastic utensils.

Rinse thoroughly and dry with a soft cloth or deerskin.

8.2 Cleaning of cooking hob components

CAUTION: do not wash these components in a dishwasher.
In normal use of the hob, the stainless steel burner caps and
pan-stands tend to be burnished by the high temperature.
Clean these parts using very fine abrasive sponges or similar
commercial products. Then use a specific paste polish to
restore the steel’s shine. Your local authorised after-sales
technician is able to supply professional products for appliance
cleaning and care.

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. In fact, humidity residues inside the
burner holes might impair burner operation.

8.2.1 Ignition plugs and safety devices

For good functioning of the lighting ignition plugs and the
safety devices, keep them very clean.
Check frequently and clean with a damp cloth when
necessary.

8.2.2 The cover

Clean the glass or steel cover, where mounted, with warm water.
Never use abrasive sponges or detergents.

Never lower the cover when burners or electric elements are
on or still hot.

Attention: the glass lid may break if overheated. Make sure that
all the burners are switched off and let them cool down before
lovering the lid.
