Instructions for the installation technician
CAUTION: This appliance must only be installed and used in rooms with
permanent ventilation to local standards.
Installation of the appliance and its connection to the electrical mains
must only be carried out by QUALIFIED PERSONEL.
Before any procedure, it is important to check that the appliance is
DISCONNECTED from the electrical mains. The Manufacturer declines all
responsibility for any damage arising from installation in breach of the
regulations in force or from failure to comply with the accident prevention
regulations.
Installation premises
For proper operation of a gas appliance, the air necessary for the combustion of
the gas must be able to flow into the room naturally. The air must flow into the
room directly through openings in the outside walls. These openings must
have an unobstructed cross-section not less than 2m3/hfor each kw of power (see
total power in kw on the appliance nameplate).
This opening must be constructed so that it will not be
obstructed from inside or outside, or constructed close
to the floor. The opening is recommended to be on the
side opposite to that on which the flue gases are
discharged. If it is not feasible to provide these openings in
the room where the appliance is installed, the necessary
air may be taken from an adjacent room, provided that:
·This room is not a bedroom or a hazardous
environment;
·This room has ventilation;
·The ventilation between the room where the appliance
is installed and the adjacent room has openings.
·Minimum height from pan support to kitchen cabinet
board is 850mm.
Discharge of flue gases
Gas cooking appliances must discharge their flue
gases through hoods connected directly to flues or the
outdoors.

If it is not possible to install the hood (fig. B) an electric fan must be installed on
the outside wall or the window of the room, provided it is possible for the
ventilation opening
to be increased in proportion to the delivery rate of the fan (fig. C). For a kitchen,
the delivery rate of this electric fan must guarantee an hourly air exchange of 3-5
times its volume. In both instances, the use of flues already used by other
appliances to discharge the flue gases is forbidden.
Connection to the gas supply
The gas Connection must be made in accordance with
the local standards. When installing, fit a safety tap at
the end of the pipeline. The appliance leaves the factory
tested and set for the type of gas indicated on the
plate inside the bottom guard, close to the gas
connection pipe. Make sure that the type of gas to be
supplied to the appliance is the same as that shown on
the plate. Otherwise, follow the instructions provided in
the “Adapting to different types of gas” section.
For maximum efficiency and minimum consumption,
make sure that the gas supply pressure complies with
the values shown in the gas used is different from that
specified (or variable).a suitable pressure regulator must
be installed on the supply pipeline.
The union must be fitted on the end of the gas train. Complete with G1/2＂
threaded nut, fitting the gasket between the components as shown in the
illustration. The gaskets must comply with the local standards. Screw the parts
together without forcing, fit the union so that it points in the direction required
then tighten all parts.
Connection
Make the connection to the gas system using a rigid metal pipe and regulation
unions, or with a stainless steel hose complying with the local standard. If metal
hoses are used, take care that they do not come into contact with mobile parts
and are not crushed. This must also be checked if the hob is to be combined with an
oven.
The gas intake connection of the appliance has a “ male thread.”
When making the connection, take care not to apply stresses of any kind to
the appliance.
When the installation is complete, always check that all the unions
are absolutely tight using a soapy solution. Never use a flame to make
this check.

9
Electrical connection
The appliance is profited to operate with a
power supply voltage of 230Vsingle-phase. The
connection must be made in accordance with the
regulations and laws in force.
Before making the connection, make sure that:
1) The safety circuit-breaker and the
electrical system are able to withstand the
load of the appliance(see nameplate).
2) The power supply system has an
earth connection in good working order in
accordance with the regulations in force;
3) The socket or omni polar switch use are easily
accessible with the appliance installed.
Fit a plug suitable for the load on the power lead and
connect it to a suitable safety socket.
If you wish to make a direct connection to the mains,
an omni polar switch with a gap between the contacts of at least 3 mm, of
suitable rating for the load and complying with the regulations in force, must
be installed between the appliance and the mains. The switch must not break a
contact in the yellow/green earth wire.
The brown live wire (connected to the “L” terminal of the terminal board)
must always be connected to the live wire of the power supply mains.
In all cases, the power supply lead must be positioned so that it does not reach
a temperature 50oC above the room temperature at any point.
One example of an ideal route is shown in the illustration. The cable is guided
by means of band clamps fixed to the side of the cabinet, in order to avoid any
contact with the appliance underneath the hob.

Adapting to the different types of
gas
Changing the nozzles
1) Remove the pan standee.
2) Remove the burner caps and flame caps from the burners.
3) Use a size 7 socket wrench to unscrew and remove the
nozzles, replacing them with those corresponding to the
type of gas to be used (see the table).
4) Reassemble the parts, reversing the operations described
above.
5) Then replace the setting data (close to the mains gas
connection) with the one for the new type of gas If the pressure of the gas
used is different from that specified (or variable), a suitable gas pressure
regulator complying with the standard must be installed on the supply pipeline.
Setting the minimum level
1) Light the burner as already described.
2) Turn the tap to the minimum flame position.
3) Remove the control knobs.
4) PG TO NG:
Use a thin blade screwdriver to turn the by-pass screw
located above left of the gas valve, shaft as shown right.
Turn gently the by-pass screw clockwise to the end
completely then turn it anti-clockwise 1/2 turn for the Triple flame burner, 3/4
turn for the Large rapid burner, 1/2 turn for the Medium Semi-rapid Burner and
3/8 turn for the Auxiliary burner.
NG TO LPG:
Use a thin blade screwdriver to turn the by-pass screw located above left of the
gas valve shaft as shown right. Turn gently the by-pass screw clockwise to the
end.
5) Finally, check that the burner does not go out when the tap is turned quickly
from the maximum to the minimum position.

Building into fitted kitchen units
740
These hobs are designed for installation in fitted kitchen units up to 600mm deep
with suitable characteristics.
Any cabinet side panels taller than the height of the hob itself must be at least
150mm away from the opening into which the hob is inserted.
The dimensions of the hob and the installation opening are shown in the illustration.
Insertion and fixing
Before inserting the hob in the
installation opening, place the special
gasket around the bottom edge of the hob.
It is important to fix this gasket
evenly, without gaps or overlapping, to
prevent liquid from seeping underneath the
hob.
1) Remove the pan stands and the
burner caps and turn the hob upside
down, taking care not to damage the
ignition plugs and the thermocouples.
2) Place the gasket around the bottom
edge of the hob as shown in the
illustration on the right.
3) Place the hob in the installation
opening and push it down so that the hob
is resting firmly on the cabinet, as
show in the illustration. The side springs
will hold it in place.

Installation options
On base cabinet with door
When constructing the cabinet, suitable precautions
must be taken to prevent contact with the casing of
the hob, which becomes very hot during operation. The
recommended method for overcoming this problem
is illustrated in fig.1
The panel underneath the hob must be easily removable
to allow the hob to be locked in position and released in
case of servicing work
On base cabinet with oven
The installation
compartment must have
the dimensions shown in
figures 2 and 3 and must
have supports to allow
satisfactory ventilation.
Two possible methods for
avoiding overheating are
illustrated in figures 3 and 4.
The electrical connections of
the hob and oven must be
made separately both for
electrical reasons and to
simplify removal of the
oven through the front of
the cabinet.
Wall cabinets or
extractor hoods must be at
least 650 mm above the hob.

Lighting the burners
To obtain a flame more easily, light the burner before placing a
cooking utensil on the pan stand
To light a burner, proceed as follow: for Version with lighting integrated in
the control knob push the knob of the burner fully down and turn
it anticlockwise to the “maximum flow” setting symbol, or press the button
if the appliance has individual lighting.
●After lighting the flame, keep the knob pressed for about 10 seconds: this
time is necessary to heat up the “thermocouple”(Fig.1-C) and activate the
safety valve, which would otherwise cut off the gas flow.
Then check that the flame is even and turn the control knob to adjust the
flame as required

In the instance of a power cut, place a flame near the burner and proceed
as already described.
If the flame does not light after a few attempts, check that the “burner cap”
and "flame cap" are correctly positioned.
To turn off the flame, turn the control knob clockwise to the ● symbol.
Before removing pans from the burners, always lower or turn off the flame.
For correct use of the hob
For lower gas consumption and better efficiency: Use only flat-bottomed pans of
dimensions suitable for the burners, as shown in the table on the right. Also, as
soon as a liquid comes to the boil take care to turn the flame down to a level that
will just keep it boiling.

Hob
Clean the hob regularly with a soft cloth wet with lukewarm water and a little
liquid detergent. Do not use the following products:
-household detergents or bleaches;
-soaped scouring pads not suitable for non-stick utensils;
-steel wool scouring pads;
-stain removers for baths or sinks.
If the hob gets very dirty, use specific commercial
products.
Ignition plug
Automatic burner ignition is provided (when installed) by a ceramic “plug” and
a metal electrode (B in fig.1). Periodically clean these parts of the hob thoroughly.
In addition, to avoid ignition difficulties, check that the cavities in the burner are
not obstructed.
To remove deposits from the burner cavities,
remove the cap and separate the two parts
(see diagram on the right). After cleaning, put
the two parts back together and return them
correctly to their position. After washing,
replace the hob pan stands, checking that
they are correctly positioned.
Routine maintenance
Have the condition and efficiency of the gas pipe and the pressure regulator
(if installed) checked periodically. If anomalies are found, do not repairs but have
the faulty part replaced.
To ensure good performance and safety, the gas regulator taps must be
greased periodically.
Periodic lubrication of the taps must only be carried out by qualified
personnel, who must also be contacted if the appliance malfunctions.
