Instruction for the User
Hob burners control knobs
The symbols on the hob burners control 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 turn it anticlockwise
to "maximum position".
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.
Then, check the flame is regular and adjust it as
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 .
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
It is also advisable, as soon as a liquid starts boiling, to
turn down the flame so that it will barely keep the liquid

Use only pans or pots with flat bottom.
Carefully supervise cookings with fats or
oil, since these types of foodstuff can result
in a fire, if over-heated.
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.
Pan Supports
Fig. 2
FO 2110
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.
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.

Instruction for the Installer
This hob 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 (Fig. 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 removed 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
Ensure that the main connection pipe does not exert
any strain on the hob.
