Instruction for the User  
Once the hob has been installed, it is  
important to remove any protective materials,  
which were put on in the factory.  
Hob burners control knobs  
The hob burners control knobs are situated on the hob  
right hand side. The symbols on the knobs mean that:  
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, push in the relevant knob and  
Fig. 1  
FO 0204  
turn it counterclockwise to "maximum position".  
After lighting the flame, 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. A) and the  
"crown" (Fig. 1, lett. B) are in the correct position.

Using the hob correctly  
To ensure maximum burner efficiency, it is strongly  
recommended that you use only pots and pans with a  
bottomfittingthesizeoftheburnerused,sothatflamewill  
not spread beyond the bottom of the vessel (fig. 2 -a).  
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.

Use only pans or pots with flat bottom.  
Carefully supervise cookings with fats or

Use of electric plates  
To switch on the plates, turn the relevant knob to the  
required position.  
The plates are regulated by a 7 position switch:  
Position 0: off  
Position 1: minimum disbursement of heat  
Position 6: maximum disbursement of heat  
The pilot light signals the connection of the electric plate.  
It is important to note that the plate may smoke  
and produce a slightly unpleasant odour when used  
for the first time. This is quite normal and will  
disappear after a short while.  
Fig. 2 - a  
Using the plates correctly  
When cooking by electric, saucepans should have a  
thick base and be perfectly flat in order to ensure  
total contact with the plate and, consequently, perfect  
conduction (Fig. 2-b).  
Occasionally, saucepans have a thin bottom and these  
loose their shape over a period of time. In this manner  
two of the qualities of the electric plate are lost: the  
even distribution of heat and the saving of energy.  
Cooking time is also lengthier.  
As regards the size of the saucepans: for best results,  
the plate and the saucepan should have the same  
diameter. The diameter of the saucepan may be  
slightly larger; a smaller diameter is not advised.  
Never leave the plates on without a saucepan! Switch  
off the plate just before the end of cooking time. The  
heat accumulated by the plate will finish cooking the  
food and save energy.  
When cooking with fats or oils maximum care  
must be taken as these can self-ignite when  
over-heated.  
Rapid plates  
The rapid plates are indicated by a red dot, and will  
heat up more quickly than a normal plate. As the red  
dots are painted on the plate, they may deteriorate during  
use and even disappear completely after a period of time.  
This will not affect the performance of the hob.  
It is important to note that the plate may smoke  
and produce a slightly unpleasant odour when  
usedforthefirsttime. Thisisquitenormalandwill  
disappear after a short while.

Before the First Use of the Appliance  
Before using the appliance remove all  
packaging, including the advertising labels  
and any protective film.  
When using the hob for the first time:  
1) place on all the plates a pan filled with some water;  
2) switch the plates on for about 10 minutes at  
“maximum” position until water inside the pans boils;  
3) then, turn the control knob to “minumum” and allow  
the plates to run for approximately 20 minutes;  
4) open a window for ventilation.  
During this time, the plates may smoke a little and  
an unpleasant odour may be emitted. This is  
absolutely normal and is caused by residues of  
manufacturing.  
Once this operation is carried out, let the plates to  
cool down, then clean them with a soft cloth soaked in  
warm water.

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.  
Regularly wipe over the hob top using a soft cloth weel  
wrung out in warm water to which a little liquid detergent  
has been added. Avoid the use of the following:  
-householddetergentandbleaches;  
-impregnatedpadsunsuitablefornon-sticksaucepans;  
FO 2110  
Fig. 3  
- steel wool pads;  
- bath/sink stain removers.  
Should the hob top become heavily soiled, it is  
recommended that a proper cleaning product is used.  
Service and original spare parts  
This machine, before leaving the factory, has been tested  
and studied by many experts and specialists, in order  
to give you the best results.  
Pan supports  
The pan supports are dishwasher proof.  
If the marks are particularly difficult to remove, use  
common non-abrasive cleaners or specific products.  
Never use steel wool pads or acids.  
Any repair work which needs to be carried out should be  
done with the utmost care and attention.  
Ignition candle  
For this reason we reccomend that for any problem you  
contact the dealer who sold it to you, or our nearest  
authorized Service Centre,  
specifying the nature of the  
problem and the particular model  
The electric ignition 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 are not obstructed.  
which you own. Always Insist on  
genuine original spare parts.  
Cleaning of the hotplates  
Spills on the hotplates should be removed using warm  
water and a soft cloth.  
Alternatively, wipe the plates with a drop of olive oil on a  
kitchen towel (while the plates are still warm).  
Periodic Maintenance  
Periodically ask your local Service Centre to check the  
conditions of the gas supply pipe and the pressure  
adjuster, if fitted.  
To ensure the good operation of the hob and its safety  
features, it is necessary that the taps are periodically  
lubricated.

Gas connection  
Choose fixed connections or use a flexible pipe in  
stainless steel in compliance with the regulation in force.  
If using flexible metallic pipes, be careful they do not  
come in contact with mobile parts or they are not  
squeezed. Use the same attention when the hob is  
combinated with an oven.  
IMPORTANT - To ensure a correct operation, a saving  
of energy and the long-life of the appliance, the voltage  
pressure of the appliance must correspond to the  
recommended values.  
The adjustable connection is fixed to the comprehensive  
ramp by means of a threaded nut GJ 1/2". Interpose the  
sealing between the components as shown in fig. 4.  
Screw the parts without forcing, adjust the connection in  
the required direction and tighten everything.  
Connection using flexible non  
metal pipes  
When the connection can be easily inspected in its full  
extent, there is the chance to use a flexible pipe  
according to the rules in force. The flexible pipe must be  
tightly fixed using clamps according to the rules in force.  
Natural gas : use the pipe fitting «D» (Fig. 4).  
LPG : use the rubber pipe holder «E».

E) RubberpipeholderforLPG  
Always insert the gasket «B». Then proceed with the  
gas connection.  
The flexible pipe should be made ready for use in such  
a way that:  
-
nowhere it can reach overtemperature, other than  
room temperature, higher than 30°C; if the flexible  
pipe, to reach the cock, must run behind the range,  
it must be installed as shown in Fig. 4;  
it is no longer than 1500 mm;  
-
-
-
-
-
it shows no throttles;  
it is not subject to traction or torsion;  
it doesn't get in touch with cutting edges or corners;  
it can be easily inspected in order to check its  
condition.  
The control of preservation of the flexible pipe consists  
in checking that:  
-
it doesn't show cracks, cuts, marks of burnings both  
on the end parts and on its full extent;  
the material is not hardened, but shows its normal  
elasticity;  
-
-
-
the fastening clamps are not rusted;  
expiry term is not due.  
If one or more abnormalities are seen, do not repair the  
pipe, but replace it.  
Important  
Once installation is complete, check the perfect  
seal of every pipe fitting, using a soapy solution,  
never a flame
