INSTALLATION
The appliance must be installed by qualified staff working in ac-
cordance with the regulations in force.
Before installing, ensure that the appliance is correctly preset for
the local distribution conditions (gas type and pressure).
The presettings of this appliance are indicated on the nameplate
shown on the cover.
This appliance is not connected to a flue gas extractor device. It
must be installed and connected in accordance with the regula-
tions in force.
This appliance may only be installed and may only operate in rooms
permanently ventilated in accordance with national regulations in
force.
VENTILATION
The rooms in which gas appliances are installed must be well ven-
tilated in order to allow correct gas combustion and ventilation.
The air flow necessary for combustion is at least 2 m
3 /h for each
kW of rated power.
POSITIONING
Remove the packaging accessories, including the films covering the
chrome-plated and stainless steel parts, from the cooker.
Position the cooker in a dry, convenient and draft-free place. Keep
at an appropriate distance from walls which may be damaged by
heat (wood, linoleum, paper, etc.).
The cooker may be free-standing (class 1) or between two units (in
class 2 st 2-1) the sides of which must withstand a temperature of
100°C and which must not be higher than the working table, in the
event of different installation arrangements with a side wall above
the working table, the wall must be at least 20 cm from the top of
the appliance.
FITTING ThE FEET (present only in a few models)
Cookers are equipped with adjustable feet to be screwed into their
front and rear corners respectively. The feet allow the height of the
appliance to be adjusted, in order to set it flush with the adjoining
unit, to level it with other worktops and to ensure even distribution
of the liquids in pans. See fig. 18
CONNECTING TO ThE GAS SUPPLY
Before connecting the cooker, check that it is preset for the gas
to be used. Otherwise, make the conversion as described in the
section headed “Adapting to different gas types”. The connection
is on the right; if the pipe has to pass behind the cooker, it must be
kept low down where the temperature is about 50°C.
- Rigid connection (see fig. 3 A + B)
The connection to the mains gas supply may be made using a
rigid metal pipe or with a metal hose. Remove the hose connector
(if already fitted) and screw the rigid union onto the threaded
connection of the gas train (see fig. 3A). The union for rigid con-
nection may already be fitted on the gas train, or may be amongst
the cooker accessories. Otherwise, it can be obtained from your
dealer.
If national regulations permit, a metal hose complying with the
national standards can be screwed directly onto the threaded
connection of the gas train, fitting a seal (see fig. 3B). However,
users are strongly recommended always to fit the rigid union.
- 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
- 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 19 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 hOB BURNER INJECTORS (Fig. 4)
- Remove the lid of the cooker by lifting it off its supports;
- remove the grids, burner caps and burners, lifting them off;
- unscrew the 2 screws (above) or nuts (below) at the back which
secure the work top, and pull it out forward.
- remove the mixer pipes and replace the injectors using a 7 mm
socket wrench.
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
