Warning and Safety instructions
11

Technical safety
~Before installation, check the gas
hob for visible signs of damage. Do not
install and use a damaged appliance. A
damaged appliance may be
dangerous.
~The electrical safety of this gas hob
can only be guaranteed if correctly
earthed. It is most important that this
basic safety requirement is observed
and tested regularly, and where there is
any doubt, the household wiring system
should be inspected by a qualified
electrician. Miele cannot be held liable
for the consequences of an inadequate
earthing system (e.g. electric shock).
~Before connecting the gas hob to
the mains electricity supply, make sure
that the data quoted on the data plate
match the household mains supply,
otherwise the appliance could be
damaged. Consult a qualified
electrician if in any doubt.
~For safety reasons, this gas hob
may only be used after it has been built
in.
~Connection to the gas supply must
be carried out by a suitably qualified
and competent person in strict
accordance with current local and
national safety regulations, e.g. a Gas
Safe registered technician in the U.K.
The gas hob may be connected via a
fused plug and switched socket. If you
wish to connect it to a fused spur
connection or if the appliance is
supplied without a plug, it must be
installed and connected to the mains
electricity supply by a suitably qualified
and competent electrician in strict
accordance with current local and
national safety regulations. The
manufacturer cannot be held liable for
damage caused by incorrect
installation or connection.
~Never open the outer casing of the
gas hob. Tampering with electrical
connections or components and
mechanical parts is highly dangerous
to the user and can cause operational
faults.
~Installation, maintenance and
repairs may only be carried out by a
suitably qualified and competent
person in strict accordance with current
national and local safety regulations.
Repairs and other work by unqualified
persons could be dangerous. Miele
cannot be held liable for unauthorised
work.
Warning and Safety instructions
12

~During installation, maintenance and
repair work, the gas hob must be
disconnected from the gas supply and
mains electricity supply.
~While the gas hob is under
guarantee, repairs should only be
undertaken by a service technician
authorised by Miele. Otherwise the
guarantee is invalidated.
~Faulty components must only be
replaced by genuine Miele original
spare parts. The manufacturer can only
guarantee the safety of the gas hob
when Miele replacement parts are
used.
~The gas hob is not intended for use
with an external timer switch or a
remote control system.
~If the connection cable is damaged,
it must be replaced by a suitably
qualified electrician with a special
connection cable of type H 05 V V-F
(pvc insulated), available from the Miele
Spare Parts Department.
~Do not connect the gas hob to the
mains electricity supply by a
multi-socket adapter or an extension
lead. These do not guarantee the
required safety of the appliance (e.g.
danger of overheating).
~Do not use the hob if it is faulty.
Switch it off immediately, and
disconnect it from the mains electricity
supply and the gas supply. Call the
Service Department.
~In areas which may be subject to
infestation by cockroaches or other
vermin, pay particular attention to
keeping the gas hob and its
surroundings in a clean condition at all
times. Any damage which may be
caused by cockroaches or other vermin
will not be covered by the guarantee.
Warning and Safety instructions
13

Correct use
~The gas hob gets hot when in use
and remains hot for quite a while after
being switched off. Do not touch it
whilst it could still be hot.
~If a cooker hood is installed above
the gas hob, ensure that the burners
are always covered with a pan when in
use. Otherwise flames could reach the
cooker hood, parts of which could then
be damaged or set on fire.
~Do not leave the gas hob
unattended whilst it is being used. Oil
and fat are potential fire hazards as
they can ignite if overheated.
~If oil or fat does catch fire, do not
attempt to put out the flames with water.
Use a suitable fire blanket, saucepan
lid, damp towel or similar to smother the
flames.
~Do not use the gas hob to heat up
the room. Due to the high temperatures
radiated, objects near the appliance
could catch fire. The life of the
appliance could also be reduced.
~Do not flambé under a cooker hood.
The flames could set the cooker hood
on fire.
~For added protection, it is advisable
to use heat-resistant pot holders or
gloves when using the gas hob. Ensure
that they 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 the gloves get damp or
wet, as this causes heat to transfer
through the material more quickly with
the risk of scalding or burning yourself.
~Do not use the gas hob as a resting
place for anything. The article could
melt or catch fire if residual heat is still
present or if the appliance is switched
on by mistake.
~Do not cover the gas hob with, e. g.
with a hob cover, a cloth or protective
foil. The material could catch fire,
shatter or melt if the appliance is
switched on by mistake or if the hob is
still warm.
~Do not use plastic or aluminium foil
containers. These melt at high
temperatures and could catch fire.
~Do not heat up unopened tins of
food on the hob as pressure will build
up in the tin, causing it to explode. This
could result in injury and scalding or
damage.
~Make sure all the components of the
gas burners have been correctly
assembled before switching on.
Warning and Safety instructions
14

~Pans must be the correct size for the
burner they are used on (see "Suitable
pans"). A pan which is too small will be
unstable on the pan support. If the pan
diameter is too large, flames can
spread out to the sides and damage or
burn the worktop, wall claddings or
surrounding units and also parts of the
hob. Miele cannot be held liable for this
type of damage.
~Ensure that the flames from the
burner do not spread out beyond the
base and up the sides of the pan.
~Unless the pan manufacturer states
that you can do so, do not use pans
with very thin bases on this gas hob,
and never heat up empty pans as they
could get damaged. This could
damage the appliance.
~The pan supports supplied must
always be used. Pans must not be
placed directly on the burner.
~Do not store any inflammable
objects near the gas hob.
~Remove splashes of fat and other
food debris from the surface as soon as
possible. These are a fire hazard.
~Replace the pan supports carefully
to avoid scratching the surface of the
hob.
~Using a gas hob results in the
build-up of heat, moisture and
combustion products in the room in
which it is installed. To ensure that
there is adequate ventilation, especially
when the gas hob is in use: make sure
natural ventilation to the room is not
hindered or use a mechanical
ventilation device (e.g. a cooker hood).
~Intensive and prolonged use of the
gas hob may result in a requirement for
additional ventilation, e.g. opening a
window or a more effective form of
mechanical ventilation, e.g. use of a
cooker hood on a higher setting.
~When using the gas hob, an
extractor hood or a ventilation device
must be used.
~When using an electrical appliance,
e.g. a hand-held food blender, near the
gas hob, ensure that the cable of the
electrical appliance does not come into
contact with the hot gas hob. The
insulation on the cable could become
damaged, giving rise to an electric
shock hazard.
~Spray canisters, aerosols and other
inflammable substances must not be
stored in a drawer under the hob.
Cutlery inserts must be heat-resistant.
Warning and Safety instructions
15

~Do not use pans that are large
enough to cover more than one burner.
The resulting build-up of heat could
damage the gas hob.
~Always ensure that food is
sufficiently cooked or reheated. Some
foods may contain micro-organisms
which are only destroyed by thorough
cooking at a sufficiently high
temperature for long enough.
Therefore, when cooking or reheating
food such as poultry, it is particularly
important that the food is completely
cooked through. If in doubt, select a
longer cooking or reheating time.
~Avoid allowing liquids or foods
containing salt to spill onto the hob. If
salty foods or liquids do get on the hob,
they should be removed as soon as
possible to avoid the risk of corrosion.
~If the gas hob is installed behind a
kitchen furniture door, it may only be
used with the furniture door open.
Do not close the door whilst the hob is
in use or whilst there is any residual
heat left in the appliance.
~If the gas hob has not been used for
a longer period of time it should be
thoroughly cleaned before it is used
again. It is also advisable to have the
appliance tested for safety.
Miele cannot be held liable for
damage caused by non-compliance
with these Warning and Safety
instructions.
Warning and Safety instructions

Disposal of the packing
material
The transport and protective packing
has been selected from materials which
are environmentally friendly for
disposal, and should 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.
Disposal of your old appliance
Electrical and electronic appliances
often contain materials which, if
handled or disposed of incorrectly,
could be potentially hazardous to
human health and to the environment.
They are, however, essential for the
correct functioning of your appliance.
Please do not therefore dispose of it
with your household waste.
Please dispose of it at your local
community waste collection/recycling
centre or contact your dealer for
advice. Ensure that it presents no
danger to children while being stored
for disposal.
Caring for the environment

sales service" section of this booklet.
Cleaning for the first time
^Remove any protective foil and stickers.
^Clean all removable parts of the burners with a solution of
warm water and a little washing-up liquid applied with a
soft sponge. Dry all parts thoroughly after cleaning and
then reassemble the burners (see "Cleaning and care").
^Clean the stainless steel trough with a damp cloth, and
then wipe dry.
Metal components have a protective coating which may
give off a slight smell when 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.
Before using for the first time
18

Rapid ignition system
The appliance is supplied with a rapid ignition system with
the following features:
–After the flame is ignited, the hob control can be released
immediately.
–Automatic re-ignition.
Should the flame be extinguished. e. g. by a gust of air, the
burner will re-ignite automatically.
If re-ignition is unsuccessful, the gas supply will be cut off
automatically (see "Safety switch-off").
Controls
The controls are used to switch on the burners and regulate
the strength of the flame.

Switching on
When using the gas hob an extractor hood or a ventilation
device must be used.
^The control for the burner required must be pressed in and
turned anti-clockwise to the largest flame symbol to switch
on. The ignitor clicks, and the gas is lit.
When a control is operated, a spark is produced on all
cooking zones. This is not a fault.
If the burner does not ignite, turn the control to "ß". Ensure
that the room is well ventilated, and wait at least 1 minute
before trying again.
If the burner does not ignite the second time, turn the control
to "ß", and see "Problem solving guide".
When switching on, re-ignition sometimes occurs (1-2 clicks)
if the flame on the ignition safety device has gone out briefly,
or if the thermal element is not hot enough, e.g. following a
gust of air.
