Installation
Any gas installation must be carried out by
qualified personnel, and in accordance with existing
rules and regulations.
The relevant instructions are to be found in the
second section of this manual.
Please, ensure that, once the appliance is
installed, it is easily accessible for the engineer
in the event of a breakdown.
WHEN THE HOB IS FIRST INSTALLED
Once the hob has been installed, it is important
to remove any protective materials, which were
put on in the factory.
THE HOB LID
In order to make the appliance match with the
kitchen design, a lid can be fitted on the hob.
- The lid (available on request) is meant to avoid dust
to settle on the hob, when it is closed, and to collect
splashes of oil or fat, when it is open. Do not use it for
any other purpose.
- Always wipe off any splash of liquid before opening
the lid.
- Always clean the lid from cooking residues before
opening it or taking it off.
WARNING! The crystal lid can splinter when
overheated. Always ensure all the burners are
off before closing it.

5
Operation
This hob is provided with a safety device, which
will stop the gas flow if the flame accidentally goes
off during cooking.
To light a burner:
- turn the relevant control knob anticlockwise to
maximum position and push it down to ignite;
- upon ignition, keep the knob pushed down about
5 seconds, to allow the safety device to be switched
off;
- then adjust the flame as required.
If the burner does not ignite, turn the control knob to
zero, and try again.
If you cannot light the flame even after several attempts,
check the "cap" and “crown” (Fig. 1, lett. A, B) are in the
correct position.
When switching on the mains, after installation or
a power cut, it is quite normal for the spark
generator to be activated automatically.
To ensure maximum burner efficiency, you should only
use pots and pans with a flat bottom fitting the size of
the burner used (see table).

diameter diameter
Large (triple crown) 180 mm 260 mm
Medium (semi-rapid) 120 mm 220 mm
Small (auxiliary) 80 mm 160 mm
))
))
)
If you use a saucepan which is smaller than the
recommended size, the flame will spread beyond
the bottom of the vessel, causing the handle to
overheat.
As soon as a liquid starts boiling, turn down the
flame so that it will barely keep the liquid
simmering.
Take care when frying food in hot oil or fat, as the
overheated splashes could easily ignite.
If the control knobs become difficult to turn, please
contact your local Service Centre.

Maintenance and Cleaning
Before any maintenance or cleaning can be
carried out, you must DISCONNECT the hob
from the electricity supply.
The hob is best cleaned whilst it is still warm, as spillage
can be removed more easily than if it is left to cool.
The Hob Top
Regularly wipe over the hob top using a soft cloth well
wrung out in warm water to which a little washing up liquid
has been added. Avoid the use of the following:
- household detergent and bleaches;
- impregnated pads unsuitable for non-stick saucepans;
- steel wool pads;
- bath/sink stain removers.
Should the hob top become heavily soiled, it is
recommended that a cleaning product such as Hob Brite
or Bar Keepers Friend is used.
Pan Supports
The pan supports are dishwasher proof. If washing them
by hand, take care when drying them as the enamelling
process occasionally leaves rough edges. If necessay,
remove stubborn stains using a paste cleaner.
The Burners
The burner caps and crowns can be removed for cleaning.
Wash the burners caps and crowns using hot soapy water,
and remove marks with a mild paste cleaner. A well
moistened soap impregnated steel wool pad can be used
with caution, if the marks are particularly difficult to remove.
After cleaning, be sure to wipe dry with a soft cloth.
Ignition electrode
The electric ignition is obtained through a ceramic
"electrode" and a metal electrode (Fig. 1 - letter C). Keep
these components well clean, to avoid difficult lighting,
and check that the burner crown holes are not obstructed.

7
SOLUTION
Check that the unit is plugged in and the electrical
supply is switched on.
Check the mains fuse has not blown.
Check the burner cap and crown have been
replaced correctly, e.g. after cleaning.
Check the main jet is not blocked and the burner
crown is clear of food particles.
Check the burner cap and crown have been
replaced correctly, e.g. after cleaning.

Building In
Building over a cupboard or
drawer
If the hob is to be installed above a cupboard or drawer it
will be necessary to fit a heat resistant board below the
base of the hob on the underside of the work surface.
Building over a kitchen unit with
door
Proper arrangements must be taken in designing the
furniture unit, in order to avoid any contact with the bottom
of the hob which can be heated when it is operated. The
recommended solution is shown in diagram 1.
The panel fitted under the hob ("a") should be easily
removable to allow easy access if technical assistance
is needed. The space behind the kitchen unit ("b") can
be used for connections. a) Removable panel

The dimensions of the cut-out are given in the diagram.
IMPORTANT
This appliance must be installed by qualified
personnel.
The manufacturer will not accept liability, should
the above instructions or any of the other safety
instructions incorporated in this book be ignored.
Gas Connection
On the end of the shaft (A) , which includes the GJ 1/2"
threaded elbow, an adjustable joint is fixed so that the
washer (B) is fitted between the components as shown
in the diagram.
A drop of paint at both edges of the "L" joint (C) will
evidence that the good seal of the connection has been
tested in the factory.
Before connecting the gas supply pipe to the joint (C),
the installer will ensure that the paint drop is unbroken
and the "L" connector has not been moved by the
vibrations during handling and transportation.
When the final connection has been made, it is essential
that a thorough leak test is carried out on the hob and
installation. Ensure that the main connection pipe does
not exert any strain on the hob.
