References to the regulations covering the gas connection to the
appliance: ISO 7-1.
aDaPTING TO DIFFERENT TYPES OF GaS
If the cooker is not already preset to operate with the type of gas
available, it must be converted. Proceed as follows:
- Replace the injectors (see table on page 20);
- regulate the primary air flow;
- regulate the minimum settings.
N.B
.: every time you change the type of gas, indicate the new type
of gas on the serial number label.
REPLacING ThE hOB BURNER INJEcTORS (Fig. 6
)
- Remove the grid, the burner caps (
a
), and the burners (
B
);
- Unscrew and remove the injector in the bottom of each injector
holder (
c
);
- replace the injector in accordance with the table in page 20 using
a 7 mm socket wrench, tighten and screw right down;
- check that the system is gas-tight;
- replace the burners, the burner caps and the grid.
IMPORTaNT
:
- Never over-tighten the injectors;
- after replacing, check that all the injectors are airtight.
REPLacING ThE OVEN BURNER INJEcTOR (Fig. 7)
- Loosen the screw which secures the bottom of the oven;
- remove the oven bottom (pulling it forward);
- remove the oven burner, after taking out the screw which secures
it;
- replace the injector using a 7 mm socket wrench.
REPLacING ThE GRILL BURNER INJEcTOR (Fig. 8)
- Remove the burner after taking out the two screws which secure
it;
- replace the injector using a 7 mm socket wrench.
IMPORTaNT:
- Never over-tighten the injectors;
- after replacing, check that all the injectors are airtight.
REGULaTING ThE BURNER aIR
Refer to the table below (indicative values) for regulation of the gap

Check operation of the burner:
- Ignite the burner at maximum flame;
- the tongue of the flame must be clear and with no yellow tip, and
must adhere closely to the burner. If too much air is supplied, the
flame detaches from the burner and may be dangerous. If the
air supply is insufficient, the flame has a yellow tip and soot may
form.
SETTING hOB BURNER MINIMUM LEVELS
If the cooker is to work on bottled gas (butane/propane), the tap
by-pass must be screwed right down.The cooker may be equipped
with type A taps, with by-pass inside (accessed by inserting a small
screwdriver into the rod) or type B taps, with by-pass on the outside
on the right (accessed directly). See figure 9.
If the cooker is to work on natural gas, proceed as follows for both
types of tap:
- Ignite the burner at maximum flame;
- pull off the knob, without using a lever against the control panel,
which might be damaged;
- access the by-pass with a small screwdriver and back off by about
3 turns (turning the screwdriver anti-clockwise);
- turn the tap rod anti-clockwise again until it stops: the burner will
be at maximum flame;
- screw the by-pass slowly back in, without pushing the screw-driver,
until the flame has apparently shrunk to 1/4 of the maximum
size, checking that it is sufficiently stable even in quite strong
draughts.
SETTING OVEN BURNER MINIMUM LEVELS
If the cooker is to work on bottled gas (butane/propane), the ther-
mostat by-pass must be screwed right down.
If the cooker is to work on natural gas, proceed as follows:
- Remove the oven bottom (loosen the screw to remove the bot-
tom);
- ignite the oven burner, turning the knob pointer to the maximum
setting;
- shut the oven door;
- access the thermostat or tap by-pass (see fig. 10);
- back off the thermostat by-pass by about 3 turns;
- after 5 or 6 minutes, turn the knob pointer to the minimum set-
ting;
- slowly re-tighten the by-pass, watching the flame decrease in size
through the window in the closed oven door until the tongue of the
flame is about 4 mm long. Never keep the flame too low. It must
be stable even when the oven door is opened or closed quickly;
- turn off the burner and replace the oven bottom.
cONNEcTING TO ThE ELEcTRIcaL MaINS
Before making the connection, check that:
- the mains voltage is as indicated on the nameplate;
- the earth connection is in good working order.
For direct connection to a power mains, a device that ensures
disconnection from the mains must be installed, with a opening
distance for the contacts that allows for a complete disconnection
under conditions of category III electrical overload, in conformity
with the installation instructions.
If the appliance power lead is not fitted with a plug, use an approved
standard type, remembering that:
- the green-yellow wire must be used for the earth connection;
- the blue wire is the neutral;
- the brown wire is live;
- the lead must never touch hot surfaces over about 75 degrees
C;
- replacement leads must be of type H05VV-F of suitable size (see
diagrams in fig. 2).
- if the appliance is supplied without lead, using type H05VV-F
cable of suitable size (see diagrams in fig. 2).
The plug must be easily accessible after the appliance is in-
stalled
.
IMPORTaNT:
the manufacturer declines all liability for damage
due to failure to comply with the regulations and standards in force.
Check that the appliance is correctly connected to the earth (see
diagrams in fig. 2 at the back of the manual).
FOR cOOKERS WITh ELEcTRIc IGNITION
If no spark is generated, do not keep on trying as this might dam-
age the generator.
Possible causes of malfunctions:
- spark plug damp, dirty or broken;
- electrode-burner gap not correct;
- spark plug wire broken or without sheathing;
- spark discharging to earth (to other parts of the cooker);
- generator or microswitch damaged;
- air has built up in the pipes (particularly if the cooker has been
out of use for a long time);
- air-gas mixture incorrect (poor fuel setting).
ThE SaFETY DEVIcE
To check that the valve is working properly, proceed as follows:
- ignite the burner and leave it to work for about 3 minutes;
