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.
Operation
Hob burners control knobs
The symbols on the hob burners control knobs
mean that:
z there is no gas supply
there is maximum gas supply
there is minimum gas supply
Lighting the burners
For easier lighting, proceed before
putting a pan on the pan support.
)
To light a burner:
z Push in the relevant knob and turn it
anticlockwise to "maximum position".
z At the same time, keep the knob pushed
down for about 5 seconds. This will allow the
"thermocouple" (Fig. 1, lett. C) to be heated
and the safety device to be switched off,
otherwise the gas supply would be interrupted.
z Then, check the flame is regular and adjust it
as required.
If you cannot light the flame even after several
attempts, check the "cap" (Fig. 1, lett. A) is in the
correct position.
To put the flame out, turn the knob to the symbol
z.
When switching on the mains, after
installation or a power cut, it is quite normal
for the spark generator to be activated
automatically.
Always turn the flame down or put it out
before taking the pans off the burner.
Using the hob correctly
To ensure maximum burner efficiency, it is strongly
recommended that you use only pots and pans
with a bottom fitting the size of the burner used, so
that flame will not spread beyond the bottom of the
vessel (See table).

FO 2295
A - Burner cap
B - Ignition candle
C - Thermocouple
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 and the aluminium
frame 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.
Fig. 2
FO 2110
Pan Supports
The pan supports are dishwasher proof. If
necessary, remove stubborn stains using a paste
cleaner. Never use steel wool pads or acids.
The Burners
The burner caps and crowns can be removed for
cleaning.
Wash the burner 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.
The cap and crown of each burner are
secured with two screws. To separate the
two pieces, lift the crown, turn it upside
down, then undo the two fixing screws as
shown in Fig. 3.
After cleaning, reassemble the two parts
and refit the cap on its correct position on
the burner.

Service Centre.
SYMPTOM
SOLUTION
„ There is no spark when lighting the gas
‹ Check that the unit is plugged in and the
electrical supply is switched on
‹ Check that the RCCB has not tripped (if

Installation
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 figure 4.
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.

Building over a kitchen unit with
oven
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.
If the hob is built into a kitchen unit with an oven
underneath, the recess must have the dimensions
shown in diagrams 2 and 3, and should also incorporate suitable oven crosspiece supports to ansure
an efficient cooling air circulation.
Diagrams 4 and 5 give two building-in examples.
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.
The electric connection of the hob and the
oven should be carried out separately, for
electrical safety reasons to permit easy
extraction of the oven from the front part
of the kitchen unit.
