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 regulations 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 installed alone or between two kitchen units; in
this case, the sides of the units must withstand a temperature of 100
degrees C and they must not be higher than the cooker hob.
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 degrees C.
- Rigid connection (see Figure 3, diagram D):
The connection to the mains gas supply may be made using a
rigid metal pipe (D). Remove the hose connector and screw the
rigid union onto the threaded connection of the gas train. The
union for rigid connection is amongst the cooker accessories.
- Connection using a rubber hose (see Figure 3, diagrams B and
C):
Connect a rubber hose carrying the conformity mark currently in
force to the hose connector. The hose must be replaced at the
date indicated, 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.
- Connection using a metal hose (see Figure 3, diagram D):
Make the connection using a hose which complies with national
standards, screwing it onto the connector with a ring seal, which
is delivered amongst the cooker accessories.
- After installation, check that all connections are airtight.
- For operation with butane/propane, check that the gas pressure
is as indicated on the nameplate.
IMPORTANT:
- 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 away from hot
surfaces.
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 12);
- 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 12, 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. 5a)
- Loose the screw securing the oven bottom;
- remove the oven bottom (push back and raise);
- remove the oven burner, after taking out its fixing screw;
- replace the injector, using a 7 mm socket wrench.
REPLACING THE GRILL BURNER INJECTOR (Fig. 5b)
- 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.
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 6.
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 (push towards the back and raise);
- 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. 7);
- 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 retighten 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.
