Installation

AUS

 Before operating your new appliance please read
this instruction booklet carefully. It contains important
information for safe use, installation and care of the
appliance.

 Please keep these operating instructions for future
reference. Pass them on to possible new owners of
the appliance.

Positioning

 Keep packaging material out of the reach of
children. It can become a choking or suffocation
hazard (see Precautions and tips).

 The appliance must be installed by a qualified
professional according to the instructions provided.
Incorrect installation may cause harm to people and
animals or may damage property.

 The room must be equipped with an air extraction

system that expels any combustion fumes. This
may consist of a hood or an electric fan that
automatically starts each time the appliance is
switched on.

Vented

The system can also provide
the air needed for combustion
indirectly, i.e. from adjacent
rooms fitted with air circulation
tubes as described above.
However, these rooms must not

be communal rooms,
bedrooms or rooms that may
present a fire hazard.

 Liquid petroleum gas sinks to the floor as it is

heavier than air. Therefore, rooms containing LPG
cylinders must also be equipped with vents to allow
gas to escape in the event of a leak. As a result
LPG cylinders, whether partially or completely full,
must not be installed or stored in rooms or storage
areas that are below ground level (cellars, etc.). It is
advisable to keep only the cylinder being used in
the room, positioned so that it is not subject to heat
produced by external sources (ovens, fireplaces,
stoves, etc. ) which could raise the temperature of
the cylinder above 50°C.

Fitting the appliance

Gas and mixed hobs are manufactured with type X
degree protection against overheating. The following
precautions must be taken when installing the hob:
 Kitchen cabinets adjacent to the appliance and

taller than the top of the hob must be at least 600
mm from the edge of the hob.

In a chimney stack or branched flue.
(exclusively for cooking appliances)

Directly to
the Outside

 The room must also allow proper air circulation, as

air is needed for combustion to occur normally. The
flow of air must not be less than 2 m

 Hoods must be installed according to their relative

installation instruction manuals and at a minimum
distance of 650 mm from the hob.

 Place the wall cabinets adjacent to the hood at a

minimum height of 420 mm from the hob (see
figure).

 Where the hob is not installed over a built-in oven, a

wooden panel must be installed as insulation. This
must be placed at a minimum distance of 20 mm
from the lower part of the hob.

Where a hob is installed above an oven without a
forced ventilation cooling system, adequate ventilation
must be provided inside the cabinet by means of air
holes through which air can pass (see figure).

! The hob can only be installed above built-in ovens
with a cooling ventilation system.

Electrical connection

Hobs equipped with a three-pole power supply cable are
designed to operate with alternating current at the voltage
and frequency indicated on the data plate (this is located
on the lower part of the appliance). The earth wire in the
cable has a green and yellow cover. If the appliance is to
be installed above a built-in electric oven, the electrical
connection of the hob and the oven must be carried out

30

separately, both for electrical safety purposes and to
make extracting the oven easier.

Electrical Connection for Gas Cooktop

Fit the supply cord with a standard plug for the
demand rate indicated on the rating plate or connect
it directly to the electrical mains. In the latter case, a
single pole switch must be placed between the
appliance and the mains, with a minimum opening
between the contacts of 3 mm in compliance with
current safety codes (the earthing wire must not be
interrupted by the switch). The power supply cord
must be positioned so that it does not reach a
temperature in excess of 50°C above room
temperature at any point.
Before actual connection make sure that:
 The fuse and electrical system can withstand the

load required by the appliance;

 That the electrical supply system is equiped with

an efficient earth hook-up according to the norms

and regulations prescribed by law;
 That the plug or switch are easily accessible.
 The wires in the mains lead are coloured in
accordance with the following code:
Green & Yellow - Earth
Blue - Neutral
Brown - Live
As the colours of the wires in the mains lead may
not correspond with the coloured markings
identifying the terminals in your plug, proceed as
follows:
Connect the Green & Yellow wire to terminal marked
E or

or coloured Green or Green & Yellow.

Connect the Blue wire to the terminal marked N or
coloured Black.

 Once the appliance has been installed, the power supply
cable and the electrical socket must be easily accessible.

 The cable must not be bent or compressed.

 The cable must be checked regularly and replaced by

authorised technicians only (see Assistance).

 The manufacturer declines any liability should these
safety measures not be observed.

Gas connection

The appliance should be connected to the main gas
supply or to a gas cylinder in compliance with current
national regulations. Before carrying out the connection,
make sure the cooker is compatible with the gas supply
you wish to use. If this is not the case, follow the
instructions indicated in the paragraph Adapting to
different types of gas.
When using liquid gas from a cylinder, install a pressure
regulator which complies with current national regulations.

 Check that the pressure of the gas supply is consistent
with the values indicated in Table 1 (Burner and nozzle
specifications). This will ensure the safe operation and
longevity of your appliance while maintaining efficient
energy consumption.

Connection with a rigid pipe (copper or steel)

 Connection to the gas system must be carried out in
such a way as not to place any strain of any kind on the
appliance.
There is an adjustable L-shaped pipe fitting on the
appliance supply ramp and this is fitted with a seal in
order to prevent leaks. The seal must always be replaced
after rotating the pipe fitting (seal provided with
appliance). The gas supply pipe fitting is a threaded 1/2
gas cylindrical male attachment.

Connecting a flexible jointless stainless steel pipe to a
threaded attach

This appliance is suitable for use with either a
flexible connection or rigid copper connection. If
installing the appliance with a flexible connection the
flexible connection must be Australian Gas
Association approved to class B of AS/NZS1869 as
a minimum.
During installation ensure that the flexible connection
be located so as to prevent excessive operating
temperatures affecting the hose. Under no
circumstance is the temperature of the flexible
connection to exceed its approved rating.
The flexible connection should also be checked
visually for any abrasion, defect or kinking and
replaced or repositioned to prevent abrasion, kinking

ment

and permanent deformation if necessary. Always

ensure that a restraining chain, if applicable, be

correctly fitted so that strain is not placed on the

household plumbing.

Gas Inlet fitting is ½ BSP (male) thread.

Fit regulator supplied for Natural Gas (if applicable)

at rear of hotplate.

It is recommended that an Isolating Valve and Union

be fitted, to enable simple disconnection for

servicing. These are to be in an accessible location.

Checking the tightness of the connection

 When the installation process is complete, check the

pipe fittings for leaks using a soapy solution. Never use a

flame.

Adapting to different types of gas

To adapt the hob to a different type of gas other than

default type (indicated on the rating plate at the base of

the hob or on the packaging), the burner nozzles should

be replaced as follows:

1. Remove the hob grids and slide the burners off their
seats.

2. Unscrew the nozzles using a 7 mm socket spanner,
and replace them with nozzles for the new type of gas
(see table 1 Burner and nozzle characteristics).

3. Reassemble the parts following the above procedure in
the reverse order.

4. Once this procedure is finished, replace the old rating
sticker with one indicating the new type of gas used.
Sticker are available from any of our Service Centres.

 Adjusting the burners primary air :
