Warning and safety instructions

This appliance complies with all relevant local and national safety requirements. Incorrect use can, however, lead to personal injury and damage to the appliance.

To avoid the risk of accidents and damage to the appliance, please read these instructions carefully before using it for the first time. They contain important notes on installation, safety, operation and care of the appliance.

Keep these instructions in a safe place and pass them on to any future user.

Correct application

This appliance is intended for

domestic use only for the preparation of food. Any other usage is at the owner's risk and could be dangerous. The manufacturer cannot be held liable for damage resulting from incorrect or improper use or operation.

This appliance is not intended for

use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience or knowledge, unless they are supervised whilst using it or have been shown how to use it correctly by a person responsible for their safety.

Warning and safety instructions

Safety with children

This appliance is only intended for

use by adults who have read these instructions. This appliance is not a toy! To avoid the risk of injury, keep children well away and do not allow them to play on or around it, or to use the controls. They will not understand the potential dangers posed by it. They should be supervised whenever you are working in the kitchen.

Older children may use the

appliance only when its operation has been clearly explained to them and they are able to use it safely, recognising the dangers of misuse.

The appliance gets hot when in use

and remains hot for quite a while after being switched off. To safeguard against burning, keep children well away from the appliance at all times.

Do not store anything which might

arouse a child's interest in storage areas above or next to the appliance. Otherwise they could be tempted into climbing onto the appliance with the risk of burning themselves.

Packaging, e.g. cling film,

polystyrene and plastic wrappings, must be kept out of the reach of babies and young children. Danger of suffocation. Dispose of or recycle all packaging safely as soon as possible.

Keep all pans out of reach of

children. Turn pan handles inwards away from the edge of the hob. Danger of burning or scalding. Special hob guards are available from good retail outlets.

Warning and safety instructions

Technical safety

Before installation, check the

appliance for visible signs of damage. Under no circumstances should you use a damaged appliance. A damaged appliance may be dangerous.

Before connecting the appliance to

the mains supply, make sure that the voltage and frequency correspond to the rating on the data plate, otherwise the appliance could be damaged. Consult a qualified electrician if in any doubt.

The electrical safety of this

appliance can only be guaranteed when continuity is complete between it and an effective earthing system which complies with local and national safety regulations. It is most important that this basic safety requirement is present and tested regularly, and where there is any doubt the household wiring system should be inspected by a qualified electrician. The manufacturer cannot be held liable for the consequences of an inadequate earthing system (e.g. electric shock).

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, it must be connected to the mains electricity supply by a suitably qualified and competent electrician in strict accordance with local and national safety regulations. The manufacturer cannot be held liable for damage caused by incorrect installation or connection.

For safety reasons, this appliance

may only be used when it has been built in.

Never open the housing of the

appliance. 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 Miele authorised person in accordance with current national and local safety regulations. Repairs and other work by unqualified persons could be dangerous. The manufacturer cannot be held liable for unauthorised work. Ensure that current is not supplied to the appliance until after installation, maintenance or repair work has been carried out.

Warning and safety instructions

If the connection cable is damaged,

it must be replaced by a suitably qualified electrician with a specialist connection cable of type H 05 VV-F (pvc insulated), available from the Miele Spare Parts Department.

Faulty components must only be

replaced by genuine Miele original parts. The manufacturer can only guarantee the safety of the appliance when Miele replacement parts are used.

During installation, maintenance and

repair work, the appliance must be disconnected from the mains electricity supply. It is only completely isolated from the electricity supply when:

– the mains fuse is disconnected,

– or the screw-out fuse is removed (in

countries where this is applicable),

– or it is switched off at the isolator.

– or it is switched off at the wall socket

and the plug is withdrawn from the socket.

Do not connect the appliance to the

mains electricity supply by a multi-socket unit or an extension lead. These do not guarantee the required safety of the appliance (e.g. danger of overheating).

Correct use

The surface of the appliance is 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.

For added protection, it is advisable

to use heat-resistant pot holders or gloves when using the appliance. 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 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.

Do not use the appliance 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.

This appliance must not be set up or

operated in the open air.

Make sure all the components of the

gas burner have been correctly assembled before switching on.

Warning and safety instructions

Pans must be the correct size for the

burner they are used on (see "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. The manufacturer 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.

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 plastic or aluminium foil

containers. These melt at high temperatures, and could catch fire.

The pan support supplied with the

appliance must always be used. Never place a pan on the burner itself.

Do not store any inflammable

objects near the gas hob.

Do not cover the appliance, e.g.

with a cloth, kitchen foil, etc. This could be a fire hazard if the appliance is switched on by mistake.

Remove splashes of fat and other

food debris from the surface as soon as possible. These are a fire hazard.

Never leave the appliance

unattended when cooking with oil or fat as these are fire hazards if overheated. Very hot oil can catch fire and could even set a cooker hood above on fire. Always heat fat slowly, watching as it heats.

If oil or fat catches 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 flambé under a cooker hood.

The flames could set the cooker hood on fire.

Unless the pan manufacturer states

that you can do so, do not use pans with very thin bases on this hob, and never heat up empty pans as they could get damaged. This could also damage the appliance.

Do not use the appliance as a

resting place for anything else. The article could melt or catch fire if residual heat is still present or if the appliance is switched on by mistake.

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.

Warning and safety instructions

Replace the pan supports carefully

to avoid scratching the surface of the hob.

Using the gas hob will cause a

build-up of heat and moisture in the room in which it is installed. Ensure that the room has sufficient natural or mechanical means of ventilation, e.g. an extractor.

If the hob is used for very long

periods of time, additional ventilation of the room may be necessary, e.g. by opening windows or doors, or running the extractor on the highest setting.

When using an electric socket near

the appliance, care should be taken that the cable of the electrical appliance does not come into contact with the hot appliance. The insulation on the cable could become damaged, giving rise to an electric shock hazard.

Always ensure that food is

sufficiently cooked or reheated. Many factors will affect the overall cooking time, including the size and quantity of the food and its temperature. 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.

Do not use a steam cleaner to clean

this appliance. The steam could reach the electrical components and cause a short circuit.

If the appliance 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. This should be done at regular intervals.

While the appliance is under

guarantee, repairs should only be undertaken by a service technician authorised by the manufacturer. Otherwise the guarantee is invalidated.

In countries where there are areas

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 may be caused by cockroaches or other vermin will not be covered by the guarantee.

The manufacturer cannot be held liable for damage caused by non-compliance with these Warning and Safety instructions.

Spray canisters, aerosols and other

inflammable substances must not be stored in a drawer under the hob. Cutlery inserts must be heat-resistant.

Caring for the environment

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.

Dispose of or recycle all packaging materials safely as soon as possible. Rather than just throwing these materials away, please ensure that they are recycled.

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. It should be disconnected from the mains electricity supply by a competent person.

Before using for the first time

Please stick the extra data plate for the appliance supplied with this documentation in the space provided in the "After 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.

Operation

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.

Should the flame be extinguished 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").

Switching on, regulating the flame and switching off

The controls are used to switch on the burners and regulate the strength of the flame.

Operation

Switching on:

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.

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.

Regulating the flame

Regulate 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 injury.

On the wok burner there is a stopper at the 6 o'clock position to prevent you turning the control to the high or low setting unintentionally.

To move from the high to the low

setting, turn the control anti-clockwise until it stops. Then press it in and continue to turn it anti-clockwise past the stopper before releasing it. You can now select the setting you require.

To move from the low to the high

setting, turn the control clockwise until it stops. Then press it in and continue to turn it clockwise past the stopper before releasing it. You can now select the setting you require.

Switching off:

^ Turn the control clockwise to position

"ß".

This stops the flow of gas and the flame goes out.

Do not turn the control past the "ß" position.

The burners can be regulated at any level between the strongest and weakest flame. Exception: The wok burner

Operation

Pans

Wok ring

Use the wok ring supplied to give additional stability, especially to woks with a rounded base.

Make sure that the wok ring is fitted securely in the correct position. See illustration.

Safety features

Thermoelectric safety ignition

This appliance is fitted with a thermoelectric ignition safety device. If the flame goes out, for example if food has boiled over or if there is a sudden draught, and automatic re-ignition has been unsuccessful, the supply of gas to the burner will be cut off.

To use the burner again, turn the

control clockwise to the "ß" position, and then switch it back on as normal.

Safety switch-off

If a burner has been used for an unusually long period (approx. 4 hours), it will switch off automatically.

To use the burner again, turn the

control clockwise to the "ß" position, and then switch it back on as normal.

Cleaning and care

General notes

Under no circumstances use a

steam cleaning appliance to clean this appliance. The steam could reach the electrical components and cause a short circuit.

The appliance should be cleaned regularly, preferably after each use. Let it cool down to room temperature before cleaning. To avoid water marks and limescale deposits, use a soft cloth to dry surfaces that have been cleaned with water.

Thoroughly remove salty food residues or liquids from the hob as soon as possible to avoid the risk of corrosion.

To avoid damaging the surface of your appliance, do not use:

cleaning agents containing soda,

–

alkalines, ammonia, acids or chlorides,

cleaning agents containing

–

descaling agents,

stain or rust removers,

–

abrasive cleaning agents, e.g.

–

powder cleaners and cream cleaners,

solvent-based cleaning agents,

–

– dishwasher cleaner,

– grill and oven cleaners,

– glass cleaning agents,

– hard, abrasive brushes or sponges,

e.g. pot scourers, brushes or sponges which have been previously used with abrasive cleaning agents,

– sharp pointed objects

(these can damage the seal between the frame and the worktop)

Cleaning and care

Stainless steel surfaces

Clean stainless steel surfaces using an E-Cloth (see "Optional accessories") or with a solution of warm water and a little washing-up liquid applied with a soft sponge. In the case of stubborn dried-on soiling, soak first. Finally, dry with a soft cloth.

The ceramic and stainless steel hob cleaner can be used when required (see "Optional accessories"). Apply with an even pressure following the direction of the "grain".

Do not use a stainless steel cleaning agent on printed surfaces. This would rub off the print. These areas should be only cleaned with an E-Cloth or with a solution of warm water and a little washing-up liquid applied with a soft sponge.

Pan supports, control knobs

Remove the pan supports. Clean the pan supports and the control knobs with a solution of warm water and a little washing-up liquid applied with a soft sponge. Stubborn soiling should be soaked first.

Finally dry all parts with a clean cloth.

Do not clean the pan supports in a dishwasher.

A conditioning agent for stainless steel can be used after cleaning to help prevent re-soiling (see "Optional accessories"). Apply sparingly with a soft cloth follow the instructions on the packaging.

Cleaning and care

Burners

Do not clean any parts of the burners in a dishwasher.

Fit wall units and extractor hood before fitting the hob to avoid damaging the surface.

fridge, fridge freezer, freezer, dishwasher, washing machine or tumble dryer.

Ensure that the gas pipe and

electrical cable are installed in such a way that they do not touch any parts of the appliance which become hot. This could cause damage.

The room in which the gas hob is

installed must be at least 51 m with a door or window in it which can be opened to the outside air.

The veneer or laminate coatings of

worktops (or adjacent kitchen units) must be treated with 100 °C heat-resistant adhesive which will not dissolve or distort. Any backmoulds must be of heat-resistant material.

This equipment may only be used in

mobile installations such as ships, caravans, aircraft etc. if a risk assessment has been carried out by a suitably qualified engineer.

An electric fryer must not be

installed directly next to a gas hob, as the gas flames could ignite the fat in the fryer. It is essential to maintain a distance of at least 300 mm between these two appliances.

in size

The electrical cable (and flexible

gas connection pipes, in countries where applicable) must be installed in such a way so that they do not come into contact with any moving kitchen parts (e.g. a drawer), and cannot become trapped.

Observe carefully the safety

distances given on the following pages.

Do not use any sealant except

where expressly instructed to do so. The seal underneath the appliance provides a sufficient seal for the worktop.

All dimensions in this instruction booklet are given in mm.

Safety instructions for installation

Safety distance above the hob

A minimum safety distance must be maintained between the hob and the cooker hood above it. See the cooker hood manufacturer's operating and installation instructions for details.

If the manufacturer's instructions are not available for the cooker hood, a minimum safety distance of at least 760 mm must be maintained. For any flammable objects, e.g. utensil rails, wall units etc. a minimum distance of at least 760 mm must be maintained between them and the hob below.

When two or more appliances are installed together below a cooker hood, e.g. a gas hob and an electric hob, which have different safety distances given in the installation instructions, you should select the greater distance of the two.

Safety instructions for installation

Safety distances to the sides of the hob

Ideally the hob should be installed with plenty of space on either side. There may be a wall at the rear and a tall unit or wall at one side. On the other side, however, no unit or divider should stand higher than the hob (see illustrations).

The following minimum distances should be adhered to for safety reasons:

– 100 mm to the right or left of the

worktop cut-out to the nearest piece of furniture (e.g. tall unit).

– 50 mm from the worktop cut-out to

the rear wall.
