Safety Regulations of Singapore,
any gas installation works
including the installation of
appliances and connection
tubing, must be undertaken by
registered gas installers who are
registered for that appropriate
classes and be employed by
registered gas contractors.

before installing and using.
The graphics in these Assembly
instructions are given as a guide
only.
The manufacturer is exempt from
all liability if this manual’s
requirements are not complied
with.
Safety instructions
When installing built-in gas hob
on top of stove cabinet, please
check that there is provision for
ventilation at the cabinet to
ensure proper operation of the
gas hob.
Do not store any flammable
materials, sprays or pressurized
containers inside the stove
cabinet.
The panel of this built-in hob is
made of tempered glass which is
safer than normal glass for this
application. However, the
following safety precautions for
using built-in hob with glass top
panel should also be noted in
order to prevent the glass top
panel from breaking:
1. Clean the burner assembly
frequently to maintain a clear gas
passage on the flame distributor.
Clean and tidy up the flame
distributor after spillage of food
and liquid once the burner
assembly cooled down.
2. Turn off the gas appliance
immediately if abnormal noise
propagates from the gas
appliance and contact an
authorized person for inspection.
3. Do not use oversized
utensils for cooking.
4. Do not impact the glass
surface with hard objects or
place heavy objects on the glass
surface.
The installation engineer has to
respect the standards and the
specifications of the gas and
electricity providers.
Before you begin, turn off the
appliance’s electricity and gas
supply.
This appliance has been designed
for home use only, not for
commercial or professional use.
This appliance cannot be installed
on yachts or in caravans.
The warranty will only be valid if the
appliance is used for the purpose
for which it was designed. Before
installing, you need to check that
local distribution conditions (gas
type and pressure) and the
appliance’s adjustment are
compatible. The appliance’s
adjustment conditions are written on
the label or the specifications plate.
This appliance can only be installed
in a well-ventilated place in
accordance with existing
regulations and ventilation
specifications. The appliance must
not be connected to a combustion
product evacuation device.
The supply cable must be attached
to the unit to prevent it from
touching hot parts of the oven or
hob.
Appliances with electrical supply
must be earthed.
Do not tamper with the appliance’s
interior. If necessary, call our
Technical Assistance Service.
Before installing
This appliance is class 3 type,
according to the EN 30-1-1
regulations for gas appliances: built-
in appliance.
These individual appliances can be
combined with other identical
appliances and/or with conventional
hobs of the same make, using the
joint accessory.
See the catalogue for details. The
units next to the appliance must be
made of non-flammable materials.
The laminated covering and glue for
adhering it must be heat resistant.
This appliance cannot be installed
above fridges, washing machines,
dishwashers or similar.
An oven must have a power cooling
fan to install a hob above it.
Check the oven’s dimensions in its
installation manual.
If an extractor fan is installed, you
must follow the installation manual’s
instructions, always keeping a
minimum distance of 650 mm to the
hob.
Preparing of kitchen unit
(fig. 1-2)
Make an appropriate size cut in the
work surface.
If there is no oven below the hob,
place a non-flammable separator
(e.g. metal or plywood) 10 mm from
the bottom of the hob. This will pre-
vent access to the base of the hob.
On wood work surfaces, varnish the
cutting surfaces with special glue.
This protects them from moisture
which could collect under the work
surface.
Installation of appliance
The clips and the adhesive seal
(underside of the hob) are factory-
fitted: do not under any
circumstances remove them. The
seal ensures that the entire work
surface will be watertight, and
prevents water seepage.
In order to fit the appliance into the
kitchen unit, first place the hob in
the correct position then loosen
each of the clips so that they all turn
freely (it is not necessary to
completely undo them).
Insert and centre the hob.
Press the sides of the hob until it is
supported around its entire perimeter.
Turn the clips and tighten them
fully. Fig. 3.
To complete the installation, the
burner covers must be fitted onto
their corresponding rings. In
addition, the pan supports must
also be located in their correct
places.
Removal of hob
Turn off the appliance’s electricity
and gas supply.
Unscrew the clips and proceed in
the reverse order to installation.

Gas connection (fig. 4)
The end of the inlet connection
point of the gas hob has a ½”
thread that allows for:
- fixed connection.
- connection using a flexible metal
pipe (L min. 1 m – max. 3 m). In this
case, it is necessary to insert the
L-tube supplied and the watertight
seal supplied between the manifold
outlet and the gas supply.
In this case, you must prevent the
pipe from coming into contact with
moving parts of the kitchen unit
being inserted (for example, a
drawer) and prevent access to any
spaces which might become
obstructed.
Warning! If any connection is
handled, check the seal.
Danger of leaks.
The manufacturer is not liable for
any connection leaking, after being
handled.
Electrical connection
Check that the voltage and power of
the appliance are compatible with
the electrical installation.
The hobs are supplied with a power
cable with a wall socket plug.
Provide an omnipolar cut-off switch
with a minimum contact separation
of 3 mm (except for plug connections,
if the user has access to it).
Appliances with plugs must only be
connected to sockets that have
earth wires correctly installed.
This appliance is type “Y”: the
supply cable can only be changed
by the Technical Assistance Service
and not by the user. The cable type
and minimum cross-section
(3 x 0.75 mm²) must be respected.
