INSTRUCTIONS FOR THE USER
It is necessary that all the operations regarding the installation, adjustment and
adaptation to the type of gas available are carried out by qualified personnel, in
conformity with the regulations in force.
The specific instructions are described in the booklet section intended for the
installer.
USING THE BURNERS
The symbols silk-screen printed on the side of the
knob indicate the correspondence between the
knob and the burner.
Automatic start-up with valves
Turn the corresponding knob anticlockwise up
to the maximum position (large flame, fig. 1) and
press the knob.
Once the burner has been started up, keep the
knob pressed for about 5 seconds.
Using the burners
In order to obtain the maximum yield without waste
of gas, it is important that the diameter of the pot is
suitable for the burner potential (see the following
table), so as to avoid that the flame goes out of the
pot bottom (fig. 2).
Use the maximum capacity to quickly make the
liquids reach the boiling temperature, and the
reduced capacity to heat food or maintain boiling.
All of the operating positions must be chosen
between the maximum and the minimum ones,
never between the minimum position and the
closing point.
The gas supply can be interrupted by turning the
knob clockwise up to the closing position.
If there is no power supply, it is possible to light the
burners with matches, setting the knob to the start-
up point (large flame, fig. 1).
BURNERS Power W Ø of pots
Auxiliary 1000 10 - 14 cm
Semi-rapid 1750 16 - 18 cm
Rapid 3000 20 - 22 cm
Triple ring 4000 24 - 26 cm
Notice
- When the equipment is not working, always check
that the knobs are in the closing position (see
fig.1).
- If the flame should blow out accidentally, the
safety valve will automatically stop the gas supply,
after a few seconds. To restore operation, set the
knob to the lighting point (large flame, fig. 1) and
press.
- While cooking with fat or oil, pay the utmost
attention as these substances can catch fire when
overheated.
- Do not use sprays near the appliance in operation.
- Do not place unstable or deformed pots on the
burner, so as to prevent them from overturning or
overflowing.
- Make sure that pot handles are placed properly.
- When the burner is started up, check that the
flameis regular and, before taking pots away,
always lowerthe flame or put it out.

heat-resistant pieces of furniture.
The walls of the pieces of furniture must resist a
temperature of 75°C besides the room one.
The equipment must not be installed near
inflammable materials, such as curtains, cloths,etc.
In the top make a hole of the dimensions as shown
in the figures at the end of this booklet with a
minimum distance of at least 50 mm from the edge
of the adjacent walls.
Any possible wall unit over the cook-top must be
placed at a distance of at least 760 mm from the
top.
It is advisable to isolate the appliance from the
piece of furniture below with a separator, leaving a
depression space of at least 10 mm (fig. 3).
If the hob is going to be installed on the top of an
oven, precautions must be taken to guarantee an
installation in accordance with current accident
prevention standards. Pay particular attention to
the position of the electric cable and gas pipe: they
must not touch any hot parts of the oven.
Moreover, if the hob is going to be installed on
the top of a built in oven without forced cooling
ventilation, proper air vents must be installed
to guarantee an adequate ventilation, with the
lower air entering with a cross section of at least
200cm2, and the higher air exiting with a cross
section of at least 60 cm2.
Fastening the top
Every cook-top is equipped with a special washer.
A set of hooks is also supplied for mounting the
cook-top.
Depending on the type of mounting surface, the
suitable type of mounting hook is supplied (hook A
or hook B).
For the installation proceed as follows:
- Remove the racks and burners from the top.
- Turn the appliance upside down and lay the
washer S along the external border (fig. 4).
- Introduce and place the cook-top in the hole made
in the piece of furniture, then block it with the
screws of the fastening hooks C (fig.5).

the gas type available (see the label under the
appliance). Follow the instructions indicated in the
chapter “gas transformations and adjustments” for
the possible adaptation to different gases.
The appliance must be connected to the gas
system by means of stiff metal pipes or flexible
steel pipes having continuous walls, in compliance
with the regulations in force.
Some models are equipped with both cylindrical A
and conical B connectors for gas supply (fig. 6).
Please select the type which is correct for the
supply concerned.
The connection must not stress the gas ramp.
Once the installation is over, check the
connection seal with a soapy solution.
Electric connection
The appliances does not require to be connected

If the equipment is adjusted for a type of gas that
is different from the one available, it is necessary
to replace the burner nozzles.
The choice of the nozzles to replace must be
made according to the table of the “technical
characteristics” as enclosed.
Act as follows:
- Remove the racks and burners.
- By means of a straight spanner L, unscrew
the nozzle U (fig.7) and substitute it with the
corresponding one.
- Tighten the nozzle strongly.
Adjusting the burners
The lowest flame point must always be properly
adjusted and the flame must remain on even if
there is an abrupt shift from the maximum to the
minimum position.
If this is not so, it is necessary to adjust the lowest
flame point as follows:
- start the burner up
- turn the tap up to the minimum position (small
flame)
- remove the knob from the tap rod
- introduce a flat-tip screwdriver in the hole F of
the tap (fig.8) and turn the by-pass screw up to a
proper adjustment of the lowest flame point.
As regards G30 gas burners, the by-pass screw
must be tightened completely.
MAINTENANCE
Replacing the battery (fig. 9)
- Unscrew the cap T .
- Replace the battery B type alkaline AA 1,5 V
placing it in the spring Mand making sure that the
“ - ” polarity faces upwards.
- Fit the battery into the battery holder and screw
down the cap T.
