1.Instruction for the User
HOB BURNERS CONTROL KNOBS
The hob burners control knobs are situated on the hob
lateral panel. The symbols on the knobs mean that :
lthere 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, push in the relevant control knob and
turn it anti-clockwise to "maximum" position. t the
same time push the electric ignition button which is
marked by a little spark.
Upon ignition, keep the knob pushed down for about 5
seconds. This will allow the "thermocouple" (Fig. 1 lett.
D) to be heated and the safety device to be switched
off, otherwise the gas supply would be interrupted.
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. ) and the
"crown" (Fig. 1 lett. B) are in the correct position.
To put the flame out, turn the knob to the symbol l.
 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 flat
bottom fitting the size of the burner used, so that flame will
not spread beyond the bottom of the vessel (see the table
beside).
It is also advisable, as soon as a liquid starts boiling, to
turn down the flame so that it will barely keep the liquid
simmering.
Carefully supervise cookings with fats or oil, since
these types of foodstuff can result in a fire, if over-
heated.

4. Mainteinance - Technical Assistance
2.Cleaning and Maintenance
 Disconnect the appliance from the electrical
supply, before carrying out any cleaning or
manteinance work.
GENERAL CLEANING
Wash the enamelled components with warm soapy
water. Never use abrasive cleaners
Frequently wash the "caps" and the "crowns" with hot
soapy water, carefully taking away any built-up of food.
If the marks are particularly difficult to remove, use
common non-abrasive cleaners or specific products.
Never use steel wool pads or acids.
AUTOMATIC IGNITION
The automatic ignition of the gas burners is obtained
through a ceramic "candle" and a metal electrode (fig. 1
lett. C). Keep these components well clean, to avoid
difficult lighting, and check that the burner crown holes
(lett. B) are not obstructed.
PAN SUPPORTS
The hobs are provided with enamelled pan supports (thin
and light - fig.2).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 necessary, remove stubborn stains using a
paste cleaner.

INSTALLATION AND ASSEMBLY
These hobs can be installed in a kitchen unit with an
opening for insertion whose dimensions are shown in
Fig. 12.
The edge of the cut out must have a minimum distance
from the rear wall of 55 mm.
If there are side walls, or sides of the furniture unit near
the hob, the cut out edges must have a minimum
distance of 100 mm. as shown in Fig. 12.
Carry out the building in of the hob as follows:
put the relevant sealings, supplied with the hob, on the
edges of the cut out, as shown in Fig. 16, taking care
that the sealings meet without overlapping;
place the hob in the cut out, taking care of its centring;
fix the hob with the relevant screws (Fig. 13). The
traction of the screws is able to trace the sealing, any
excess of which can then be easily removed.
The edge of the hob forms a double labyrinth seal which
provides a total guarantee against infiltration of liquids.
