Keep these instructions in a safe
place for reference and pass them
on to any future user.
Building in and connection
The connection to the gas supply
must be carried out by a suitably
qualified and competent person in accordance with local and national safety
regulations, e.g. a Corgi registered service technician in the U.K. If the appliance is supplied without a plug, or if
the plug is removed the appliance
must additionally be installed and connected by a suitably qualified and competent electrician in strict accordance
with national and local regulations. The
manufacturer cannot be held responsible for damage caused by incorrect
installation or connection.
The electrical safety of this ap-
pliance can only be guaranteed
when continuity is complete between
the appliance and an effective earthing
system.
It is imperative that this basic safety requirement be tested and where there is
any doubt, the electrical system of the
house should be checked out by a
qualified electrician. The manufacturer
cannot be held responsible for damage
such as electric shock caused by the
lack or inadequacy of an effective earthing system.
Ensure that the gas pipe and elec-
trical cable are installed in such a
way that they do not touch any parts of
the appliance which become hot. This
could cause damage.
Do not connect the appliance to
the mains electricity supply by an
extension lead. Extension leads do not
guarantee the required safety of the appliance.

Warning and Safety instructions
Correct usage
For safety reasons the appliance
must only be operated after it has
been built in. This is necessary to ensure that all electric components are
shielded.
This appliance is for domestic use
only, and is not intended for commercial use.
Use this appliance for the prepara-
tion of meals only. Any other usage
is at the owner’s risk and could be dangerous. The manufacturer can not be
held responsible for damage caused
by improper use or misuse of the appliance.
Do not use the appliance to heat
up the room. The high temperature
could cause inflammable objects
nearby to catch fire.
Ensure the room in which the gas
hob is installed has sufficient ventilation. In a small kitchen it may be advisable to keep the door open if using
the hob for extended periods.
Make sure all the components of
the gas burners have been cor-
rectly assembled before switching on.
When using a cooker hood over
the gas hob, ensure that any burners in use are always covered with a
pan. Otherwise flames could be drawn
up by the suction of the cooker hood,
parts of which could then be damaged
or even set on fire.
Do not use pans with too large a
base diameter. Using larger pans
may cause the flames to spread out
and damage or burn the worktop or surrounding units.
For safety and stability do not use
pans with a base diameter smaller
than the pan support.
Do not store any inflammable ob-
jects near the gas hob.
This appliance must not be set up
or operated in the open air.
5
Warning and Safety instructions
Protecting the appliance from
damage
Under no circumstances use a
steam cleaning appliance to clean
the gas hob. Pressurised steam could
cause permanent damage to the surface and to components, for which the
manufacturer cannot accept responsibility.
Do not let salty foods or liquids get
on the hob. These should be
removed as soon as possible to avoid
the risk of corrosion.
In countries which may be subject
to infestation by cockroaches or
other vermin, pay particular attention to
keeping the appliance and its surroundings in a clean condition at all times.
Any damage which might be caused
by cockroaches or other vermin will not
be covered by the appliance guarantee.
Protection from burning
The appliance heats up and re-
mains hot for quite a while after it
has been switched off. Keep children
away.
Do not store anything which might
arouse a child’s interest in storage
areas above or next to the hob. Otherwise they could be tempted into climbing onto the appliance with the risk of
burning themselves.
Use heat-resistant pot holders or
gloves when handling hot pots and
pans. Ensure that the pot holders do
not come into contact with the flames.
Do not use large cloths, tea towels or
similar as the ends could touch the
flames and catch fire. Take care not to
let pot holders or gloves get damp or
wet, as this causes heat to transfer
through the material quicker with the
risk of burning yourself.
To prevent the risk of children
reaching pan handles and pulling
pans over with the danger of burning or
scalding themselves be sure to turn
pan handles inwards and out of their
reach. Special hob guards are available from good retail outlets as additional protection.
Do not heat up unopened tins of
food on the hob as pressure will
build up in the tin and it can explode.
This could result in injury or damage.
6
Warning and Safety instructions
Do not use the hob as a resting
place for anything else. If the hob
was switched on inadvertently, or if it
was still hot the article could begin to
melt or catch fire.
Remove splashes of fat and other
food debris from the surface as
soon as possible. These are a fire hazard.
Do not cover the hob with a cloth,
household foils or other similar objects. This could lead to danger of the
article catching fire, if the hob were to
be switched on inadvertently.
Never leave the hob unattended
when cooking with oil or fats as
these are fire hazards if overheated.
Overheated fat could catch fire and
even set the cooker hood on fire.
If oil or fat does catch fire despite
this do not attempt to put out the
flames with water. Use a suitable fire
blanket or fire extinguisher.
Do not flambé under a cooker
hood. Otherwise flames could be
drawn up by the suction of the cooker
hood, parts of which could then be
damaged or even set on fire.
Ensure that the flames from the
burner do not spread out beyond
the base and up the sides of the pan.
Spray canisters, aerosols and
other inflammable substances
should not be stored in a drawer under
the hob if there is no shelf separating
the drawer from the hob. If cutlery inserts are to be placed in the drawer
these must be made of a suitable heatresistant material.
7
Warning and Safety instructions
With a damaged appliance
In the event of damage or a de-
fect, switch off the appliance immediately. Turn off the gas supply tap,
and disconnect completely from the
electricity supply. The appliance is
only completely isolated from the electricity supply when:
- the mains fuse is withdrawn, or
– it is switched off at the wall socket
and the plug removed (pull on the plug,
not the cable).
Contact the Service department.
Ensure that the appliance is disconnected from the electricity supply before any servicing or repair work.
Repairs to the gas and electrical
components of this appliance must
only be carried out by a suitably qualified person. Repairs by unauthorised
personnel could be dangerous. On no
account open the outer casing of the
appliance.
While the appliance is under guar-
antee repairs should only be undertaken by a service engineer authorised
by the manufacturer. Otherwise the
guarantee is invalidated.
Further safety notes
When using an electric socket
near the hob, care should be taken
that the cable of the electrical appliance does not come into contact
with the gas flames or the hot parts of
the hob. The insulation on the cable
could become damaged, giving rise to
an electric shock hazard.
Always ensure that food is suffi-
ciently cooked or reheated. Some
foods may contain micro organisms
which are only destroyed by thorough
cooking, therefore when cooking or reheating foods, e.g. poultry, select a
longer cooking or reheating time.
Do not use plastic or aluminium foil
containers. These melt at higher
temperatures. Fire hazard.
Never heat up empty pots or pans
on the hob as this could damage
them.

Before using for the first time
9
Before using for the first time
Disposal of the packing
material
The transport and protective packing
has been selected from materials
which are environmentally friendly for
disposal and can normally be recycled.
Ensure that any plastic wrappings,
bags etc. are disposed of safely and
kept out of the reach of babies and
young children. Danger of suffocation!
Rather than just throwing these materials away, please ensure that they
are offered for recycling.
Disposal of your old appliance
Old appliances contain materials which
can be reclaimed or recycled. Please
contact your dealer, your local waste
collection centre or scrap merchant
about potential recycling schemes.
Before disposing of an old appliance, ensure that disconnection
from the gas supply is made by a
suitably qualified and competent
person. Switch off at the mains electricity supply. Cut off and render
any plug useless. Cut off the cable
directly behind the appliance to prevent misuse. This should be done
by a competent person. Ensure that
the appliance presents no danger
to children while being stored for
disposal.
The manufacturer cannot be held
liable for damage caused by noncompliance with these safety instructions.
10
Before using for the first time
Cleaning and heating up for
the first time
Before using for the first time clean the
hob and all removable parts as follows:
The removable parts of the gas burner assembly can be washed in a
mild solution of water and washingup liquid. Wipe dry and reassemble
in the correct order (see “Cleaning
and care”).
Clean the hob with a damp cloth
only, and then wipe dry.
Metal components have a protective
coating which may give off a slight
smell when the hob is heated up for the
first time. The smell and any vapours
will dissipate after a short time and do
not indicate a faulty connection or appliance.
11
Using the gas hob
Using the gas hob
Switching on, Switching off,
Controls
The control knobs are used to switch
on the burner and regulate the strength
of the flame.
ß the gas supply is turned off
& strong flame
/ weak flame
Switching on:
The control knob for the burner required must be pressed in and
turned anti-clockwise to the large
flame symbol to switch on.
When the flame ignites, keep the
control pressed in for 8-10 seconds,
and then let it go.
If the flame goes out, repeat the procedure, keeping the control knob pressed
in for a few extra seconds.
With the knob no longer pressed in
you can continue turning it towards
the small flame symbol.
Control the flame so that it does not
spread out beyond the sides of the
pan. As the outer part of the flame is
much hotter than the centre, the tips of
the flames should stay beneath the pan
base. Flame tips which extend beyond
the sides of the pan merely warm up
the air in the room and can also damage pan handles and increase the
danger of burning.
Switching off:
Turn the knob clockwise until the ß
position is reached.
This stops the flow of gas and the
flame goes out.
Remember: Turn anti-clockwise to
switch on, turn clockwise to switch
off. The control knob cannot be
turned anti-clockwise from the small
flame symbol to the ß position.
12
Using the gas hob
Pans
Pan size
– The simple rule: a large pan for the
large flame, a small pan for the small
flame.
– Wide, shallow pans are preferable to
narrow, tall ones. They heat up more
quickly as there is room for more
flame under the base.
– Do not use pans with too large a
base diameter.
Using larger pans may cause the
flames to spread out and damage or
burn the worktop or surrounding
units.
Suitable pans
Any heat-resistant pans can be used
on a gas burner.
Pan bases do not need to be even for
cooking, (in contrast with those used
on an electric hob). Through the
spreading action of the flame, heat
reaches all parts of the base.
Thick pan bases reduce the risk of
food overheating in places, as heat is
better distributed.
Thin pan bases conduct heat to the
food inside more quickly than thicker
ones. However as the heat is not
evenly distributed over the pan base
there is a danger that food may heat up
unevenly. Stir the food frequently.
– Do not use small pans with high
flame settings as the flames can lick
up the sides of the pan.
– Pans with a smaller diameter than
the pan support or pans which do
not sit securely are hazardous and
should not be used.
13
Using the gas hob
Safety cut-out
This appliance is fitted with an electric
ignition safety device which cuts off the
supply of gas to a burner if the flame
goes out, for example if food has
boiled over, or if there was a sudden
draught.
To use the hob again, turn the knob
clockwise until the ß position is
reached and switch on as normal.
The safety cut-out operates independently from the electricity supply.
This means that it is still active when
the hob is used during a power cut
(see "Use during a power cut").
Use during a power cut
If there is an interruption to the electricity supply the gas can be ignited
with a match:
Press in the relevant control knob
and turn it anti-clockwise to the large
gas symbol.
Hold the control pressed in and light
the gas at the burner with a match.
Keep the control knob pressed in for
a further 8-10 seconds and then release it.
14
Cleaning and care
Cleaning and care
Under no circumstances use a
steam cleaner to clean this appliance. Pressurised steam could
cause permanent damage to the
surface and to components, for
which the manufacturer cannot accept responsibility.
Do not use any sharp pointed objects which could damage the seal
between the frame and the worktop.
Never use scouring agents, pads,
abrasive cleaning agents, or strong
cleaners e.g. oven sprays, stain or
rust removers, as these could damage the surface of the appliance.
Keep the ignitor in the burner dry. If
it gets wet it will not spark.
After cleaning the hob must be thoroughly dried with a soft cloth to prevent a build up of limescale deposits
Let your appliance cool down to a safe
temperature and remove the pan supports. Clean the pan supports, hob surfaces and control knobs with a sponge
and a mild solution of warm water and
washing up liquid. Soak baked or hardened spills.
Dry the hob surfaces and pan supports
thoroughly after cleaning.
The stainless steel surface of the hob
can be cleaned using a proprietary
non-abrasive cleaning agent designed
for use on stainless steel surfaces.
Apply with an even pressure following
the direction of the "grain".
Thoroughly remove salty foods or
liquids from the hob as soon as
possible to avoid the risk of corrosion.
15
Cleaning and care
Burners
The burners can be dismantled for
cleaning when cold.
Dismantle as follows:
Remove the burner parts and wash
in a solution of hot water and washing-up liquid. Then dry them thoroughly. Make sure that the flame
holes are clean and completely dry.
The shiny surfaces of the burner caps
will become more dull with time and
usage. This is normal and will not affect
the operation of the hob.
Wipe all removable parts of the burner with a damp cloth and then dry.
Gently wipe the ignitor and the ignition safety control with a well wrungout cloth and wipe dry with a clean
cloth.
16
Cleaning and care
Re-assemble the burner as follows
(see illustration):
Important:
Replace parts in the correct order.
Place the burner head on to the burner
base so that the ignitor and the ignition
safety control extend through their respective holes in the burner head. The
burner head must click into place correctly.
Replace the burner cover and make
sure that the locating tabs in the burner head fit into the notches in the
cover.
Replace the pan support.
