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 STAFF.
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 deriving from installation in breach of the
regulations in force or from failure to comply with the accident prevention
regulations.
10

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 must be no 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 indoors or out and placed close to the floor,
preferably 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 is not in a vacuum;
·the ventilation between the room where the appliance is
installed and the adjacent room is guaranteed by permanent
openings.
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.
11

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 GJ1/2＂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.
12

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 in 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.
Replacing the power supply lead
If the lead has to be replaced, only HO5RR-F or
HO5RN-F type cables suitable for the load and the
operating temperature must be used. In addition, the
yellow/green earth wire must be about 2 cm longer than
the live and neutral wires.
13

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 piped 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) Use a thin straight screwdriver to turn the by-pass pin located
next to the tap rod (see fig. B ).For LPG, turn the by-pass pin
fully clockwise.
The result should be a small, homogeneous flame which is
uniform around the entire burner ring. For the dual Triple A
Flame version see fig. A. by-pass 1 central burner, by-pass 2
both burners.
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
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 under meath 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.
15

Installation options
On base cabinet with door
When constructing the cabinet, suitable precautions must be take
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 lacked in position and released incase 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.
