INSTALLATION
The appliance must be installed by qualified staff working in
accordance with the installation 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 label 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
operate in rooms permanently ventilated in accordance with
national regulations in force.
ROOM VENTILATION
The rooms in which gas appliances are installed must be well
ventilated in order to allow correct gas combustion and
ventilation.
The airflow necessary for combustion is at least 2 m
3
/h for each
kW of rated power.
POSITIONING (fig. 3)
Remove the hob from the packaging accessories, including the
films covering the chrome-plated and stainless steel parts. Place
the hob well away from items of furniture with sides higher than
the built-in hob. In addition, any separating wall parallel to the
work surface must be at least 1 cm below the hob casing, and
an opening 10 cm square must be provided underneath the gas
hose elbow. You are advised to make the gas connection before
positioning the hob in the supporting unit.
FIXING
A self-adhesive gasket (A) is supplied with the hob, and must
be placed under the edge of the box unit, as close as possible
to the edge itself (fig. 4). The gasket must fit all the way round
for a perfect seal, preventing moisture from getting beneath the
hob. Place the appliance in the hole in the hob, making sure
that the adhesive gasket provides a firm seal between the edge
of the hob and the surface of the unit (fig. 5), and adjust the
hooks already inserted in the casing (fig. 6).
CONNECTING TO THE GAS SUPPLY
Before connecting the hob, check that it is preset for the gas to
be used. The connection to the appliance is made on the left. If
other heating devices nearby mean there is a risk the hose may
overheat to above 30°C (e.g. if the line passes above another
appliance) a rigid pipe must be used.
Use of a rigid pipe (fig. 7) is compulsory both for operation with
natural gas and for operation with liquid gas.
In case of operation with liquid gas, the connection may also be
made using a standard rubber hose (fig. 8) provided the rubber
hose can be inspected along its entire length.
The hose must be replaced at the indicated date at the latest,
and must be secured at both ends using standard hose clamps.
Use a hose carrying the mark certifying conformity with the
standards in force.
IMPORTANT:
- After installation, check that the connections are airtight.
- For operation with B/P gas, check that the gas pressure is as
indicated on the nameplate.
- Use only standard rubber hoses. For LPG, use a hose and
pressure regulator which comply with the national standards
in force. For the hose connection: ISO 7-1.
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 socket is not easily accessible, the installation engineer
must provide a switch with contact breaking gap of 3 mm or
more.
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 75°C;
- replacement leads must be of type H05RR-F or H05V2V2-F
of suitable size (see fig. 2) for gas and all-electric appliances,
and of type FR3R3 of suitable size (see fig. 2) for mixed
appliances;
- the power supply lead must only be replaced by a qualified
technician.
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
fig. 2).
FOR HOBS WITH ELECTRIC IGNITION
The correct gap between the electrode and the burner is shown
in figure 9a and 9b.
If no spark is generated, do not keep on trying as this might
damage the generator. Possible causes of malfunction:
- 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 hob);
- generator or microswitch damaged;
- air has built up in the pipes (particularly if the hob has been out
of use for a long time),
- air-gas mixture incorrect (poor fuel setting).
THE SAFETY DEVICE
The correct gap between the end of the thermocouple sensor
and the burner is shown in figure 9a and 9b.
To check that the valve is working properly, proceed as follows:
- ignite the burner and leave it to work for about 3 minutes;
- turn off the burner by returning the knob to the off position (•);
- after 90 seconds, turn the knob pointer to the “on” position;
- release the knob in this position and move a burning match
towards the burner: IT MUST NOT IGNITE.
Time needed to excite the magnet during ignition: 10 seconds
approx.
Automatic tripping time, after flame has gone out: not more than
90 seconds.
IMPORTANT
- Before carrying out any work inside the appliance, disconnect
the mains plug and shut off the gas tap.
- Never use matches to check for gas circuit for leaks. If a specific
control device is not available, foam or very soapy water can
be used.
- When re-closing the hob, check that the electric wires of the
spark plugs (if present) are not close to the injectors, so that
they cannot run across them.
