GB
- Connection using a rubber hose (see fig. 3C). (For butane/propane
gas only).
Connect a rubber hose carrying the conformity mark currently in
force to the hose connector. The hose must be replaced at the
date indicated at the latest, and must be secured at both ends
using standard hose clamps. It must be absolutely accessible to
allow its condition to be checked along its entire length.
CAUTION:
- Use of the hose connector is only permitted for free-standing in-
stallation. If the appliance is installed between two class 2 st. 2-1
unions, the rigid union is the only form of connection permitted.
IMPORTANT:
- After installation, check that the connections are airtight.
- For operation with butane/propane, check that the gas pressure
is as indicated on the nameplate.
- Use only standard rubber hoses. For LPG, use a hose which
complies with the national regulations in force.
- Avoid sharp bends in the pipe and keep it well way from hot sur-
faces.
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 29);
- 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. 4)
- 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 29 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. 5)
- 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. 6)
- 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
H in mm (fig. 6 for the grill).

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 7.
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. 8);
- back off the thermostat by-pass by about 3 turns;
- after 5 or 6 minutes, turn the knob pointer to the minimum setting;
- 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.
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 H05RR-F or H05V2V2-F of
suitable size (see diagrams in fig. 2).
- if the appliance is supplied without lead, using type H05RR-F or
H05V2V2-F cable of suitable size (see diagrams in fig. 2).
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
The correct gaps between the electrode and the burner are shown
in figures 5 and 6.
