z This hob is intended for domestic cooking
only. It is not designed for commercial or
industrial purposes.
• Appliances become very hot with use,
and retain their heat for long periods after
use. Care should be taken to avoid
touching heating elements inside the hob.
• Always stand back from the hob when
opening the hob door during cooking
or at the end of it to allow any build up
of steam or heat to release.
z When in use a gas cooking hob will pro-
duce heat and moisture in the room in
which it has been installed. Ensure there
is a continuous air supply, keeping air
vents in good condition or installing a
cooker hood with a venting hose.
z When using the hob for a long period
time, the ventilation should be improved,
by opening a window or increasing the
extractor speed.
z Do not use this hob if it is in contact with
water. Do not operate the hob with wet
hands.
z Ensure the control knobs are in the ‘OFF’
position when not in use.
z When using other electrical appliances,
ensure the cable does not come into
contact with the hot surfaces of the
cooking appliance.

z Unstable or misshapen pans should not
be used on the hob as unstable pans can
cause an accident by tipping or spillage.
z Never leave the hob unattended when
cooking with oil and fats.
z Never use plastic or aluminium foil dishes
on the hob.
z Perishable food, plastic items and aerosols
may be affected by heat and should not
be stored above or below the hob unit.
z This appliance is not connected to a
combustion products evacuation device.
It must be installed and connected in
accordance with current installation
regulations. Particular attention shall be
given to the relevant requirements
regarding ventilation.
z Ensure a good ventilation around the
appliance. A poor air supply could cause
lack of oxygen.

The hob is supplied with a 3 core flexible
supply cables.
This has to be provided with a proper plug,
able to support the load marked on the
identification plate. To connect the plug to the
cable, follow the recommendation given in
diagram aside. The plug has to be fitted in a
proper socket.
In the event of having to change the fuse, a
3amp ASTA approved (BS 1362) fuse must
be used.
Should the plug need to be replaced for any
reason, the wires in the mains lead are
coloured in accordance with the following
code:

In the case of a permanent connection, it is
necessary that you install a double pole switch
between the hob and the electricity supply

the switch contacts and of a type suitable for
the required load in compliance with the
current electric regulations.
The switch must not break the yellow and

NOTE - Should it be found that the fuse has
failed but no fault is indicated - a detailed
continuity check (i.e. by disconnecting and
checking each component) is required to trace
the faulty component.
It is possible that a fault could occur as a result
of local burning/arcing but no fault could be
found under test. However a detailed visual
inspection should reveal evidence of burning
around the fault.

When the hob has been fully installed it will
be necessary to check the minimum flame
setting.
To do this, follow the procedure below.
z Turn the gas tap to the MAX position and
ignite.
z Set the gas tap to the MIN flame position
then turn the control knob from MIN to
MAX several times. If the flame is unstable
or is extinguished follow the procedure
below.

Proper arrangements must be taken in
designing the furniture unit, in order to avoid
any contact with the bottom of the hob which
can be heated when it is operated. The
recommended solution is shown in diagram
3.
The panel fitted under the hob ("a") should
be easily removable to allow easy access if

Carry out the building in of the hob as
follows:
1. place the seals supplied with the hob
on the front edge of the cut out. Then,
place them at 86 mm from the side
edges and at 10 mm from the rear
edge, as shown in the diagram, taking
care that the seals meet without
overlapping.
2. Place the hob in the cut out, taking
care that it is centred.
3. Fix the hob with the relevant fixing
clamps, supplied with the injectors kit
(see diagram). When the screws have
been tightened, the excess seal can be
removed.
The edge of the hob forms a double seal which
prevents the ingress of liquids.

cm2 is required. If it is installed in a room of
volume between 5 m3 and 10 m3 an air vent
of effective area of 50 cm2 is required, while

As soon as a liquid starts boiling, turn
down the flame so that it will barely
keep the liquid simmering.
If the control knobs become difficult
to turn, please contact your local
Service Force Centre.
When switching on the mains, after
installation or a power cut, it is quite
normal for the spark generator to be
activated automatically.
In the absence of electricity, ignition
can occur without the electrical device;
in this case, approach the burner with
a flame, push the relevant knob down
and turn it anti-clockwise until it
reaches the “maximum” position.
Using the hob correctlyUsing the hob correctly
Using the hob correctly
Using the hob correctlyUsing the hob correctly
To ensure maximum burner efficiency, it is
strongly recommended that you use only pots
and pans with a
the burner used, so that flame will not spread
beyond the bottom of the vessel (see the
table).
Use only pans or pots with flat bottom.
The stainless steel can become
tarnished if excessively heated.
Therefore prolonged cooking with
potstones, earthenware pans or castiron plates is inadvisable. Also, do not
use aluminium foil to protect the top
during use.
Make sure pots do not protrude over
the edges of the cooktop and that they
are centrally positioned on the rings
in order to obtain lower gas
consumption.
Do not place unstable or deformed
pots on the rings: they could tip over
or spill their contents, causing
accidents.
