for connection and functions

Before the appliance is installed, it must be checked whether the local supply conditions (type of gas and gas pressure) and the settings of the appliance correspond. All settings for the appliance are stated in this user guide. This appliance should not be connected to a pipe for extracting combustion products. It must be fitted and connected in accordance with the applicable conditions of installation. Particular attention should be paid to suitable ventilation measures. The use of a gas cooker causes heat and humidity to build up in the room where the cooker is installed. For this reason it should always be ensured that the kitchen is well ventilated; keep the ventilation slits open or provide for a mechanical ventilation facility (e.g. a cooker hood). If the appliance is subject to particularly intensive use or use over a long period of time, it might be necessary to provide for additional ventilation, e.g. by opening a window or operating a cooker hood at a high power level.

Küppersbusch cookers are made according to the applicable safety regulations. Only Küpperbusch ovens may be connected to Küpperbusch hobs.

The appliance should only be connected to the gas mains by a qualified gas fitter. The same applies for all adjustments and conversions. Attention must be paid to the statutory regulations at all times. It is also necessary to observe the instructions of the relevant gas board for connecting up the appliance.

The cooker should only be installed in a well ventilated area. Do not use the cooker for heating rooms.

If problems occur during operation the gas supply should be turned off immediately.

The appliance should only be serviced and repaired by a qualified technician in accordance with the applicable safety regulations. When repair jobs are being carried out on any equipment running on gas, it is always important to turn off the gas supply. Work carried out incorrectly places your safety at risk.

If the cooker is run on liquefied petroleum gas (propane/ butane) it is vital to ensure that all joints between the gas bottle and the cooker are secure and tight.

External flexible supply hoses should not be wedged into tight positions or laid cross hot surfaces.

The surfaces of the oven, oven door and hob are very hot when in operation. Always keep children away!

Connection leads of electrical appliances should not be placed on the hot hob or be allowed to become jammed in the hot oven door.

Do not lift the appliance by the handle of the oven door. We recommend that you have the appliance serviced at regular intervals.

WARNING! This appliance must be earthed!

for the gas hob

Cooker hoods above the hob must be fitted at a minimum distance of 650 mm. The rings should not be ignited unless you are cooking something.

Always ensure that the burner covers are in the correct position. Attention: The electronic automatic spark ignition will not work if there is

a power failure! In such cases please use matches. Overheated fats and oils may spontaneously ignite. Food cooked in fat or

oil, e.g. chipped potatoes, should only be cooked under supervision. Never extinguish ignited fats and oils with water! Put the lid on the pan, switch off the ring and remove the pan from the hot hob.

Pressure cookers should be constantly supervised until the correct pressure has been reached. First turn the burners of the rings up to maximum flame and then (following the instructions of the manufacturer of the pressure cooker) turn the heat down in good time.

The ventilation slits in the hob should not be covered over. If cracks, fractures or any other defects appear in your glass ceramic

hob, immediately switch off the appliance. Disconnect the fuse.

for the oven

When carrying out repairs and replacing oven light bulbs, the cooker must be disconnected from the mains (switch off the fuse).

Never store any objects in your oven which could cause a hazard if the oven is unintentionally switched on.

Take special care when working in the hot oven. Use a dish cloth, oven gloves or similar.

The oven door must close well. In the event of damage to the door sealing, hinges, sealing surfaces or to the glass pane, do not use your cooker until it has been repaired and checked by a qualified and authorised trained installer.

Caution! When opening and closing the oven door, do not reach into the hinge. Risk of injury!

Always close the oven door completely when preparing food in the oven.

Keep at least 5 cm away from the grill and top heat

During use, open and shut the oven door with care to prevent the burner flames being extinguished.

The ventilation slots in the hob serve to ventilate the oven and should not be covered!

Do not spend more than 15 seconds attempting to ignite the oven flame when the door is closed. If the attempt is unsuccessful after this time period, open the oven door and ventilate for at least one minute before trying again.

Disposing of the packaging and the old appliance

Dispose of the transport packaging in such a way that is not harmful to the environment. If the appliance is purchased in Germany the dealer who sold you the appliance will dispose of the transport packaging for you. Recycling the packaging saves raw materials and reduces the amount of waste disposed appliances still contain useful materials. Dispose of your old appliance at a collection point for recycling useful materials. Before disposing of your old appliance ensure that it cannot be used any longer. This will prevent misuse.

Initial Cleaning

Remove excess materials and packaging. Before preparing food for the first time, the cooker must be cleaned. Clean the glass ceramic cooking area or hob, baking trays, drip pan etc. with a damp cloth and a little detergent.

Heating the hob (not for glass ceramic hobs)

Consecutively heat up the hotplates for 5 minutes each at the highest setting. Air the kitchen well because of the “new smell”.

Heating the oven

Close the oven door. Heat up the oven with bottom heat at maximum temperature for 60 minutes. Air the kitchen well at the same time.

Setting the real time

After the appliance has been connected up the mains for the first time or af-

ter a power failure “0.00" will appear in the display.

Press both keys simultaneously for a short time and once the ”Plus” or ”Minus” key.

Immediately afterwards set the current time by actuating one of the two setting keys.

Setting the minute minder

The minute minder is intended to remind yuo when the cooking time or the roasting time has come to an end. This is its sole function and does not affect the operations of the oven. After the expiry of the set time, an acoustic signal will sound.

Press the setting key on the right until the required cooking time appears in the display. The symbol will light up and the set time will begin to count down.

A signal will sound when the set time has come to an end. The current time will reappear in the display.

To switch off the signal, briefly press one of the setting keys.

Unless the signal is switched off by hand, it automatically stops after approx. 2 minutes. The cooking symbol flashes until the alarm is switched off.

Take note of the safety instructions on page 22!

Switching the cooking zones on and off

Each cooking zone has its own regulator, which can be pushed down. The symbols on the control panel indicate which regulator operates which cooking zone. The cooking zone burners are ignited by an electric spark. They can also be lit with matches or something similar (e. g. in the event of power failure).

Igniting the cooking zone burners:

- Release the depressed cooking zone regulator by pressing down.

- Turn the regulator anti-clockwise to the high position and press in halfway, until a resistance can be felt. The flame has been ignited.

- Keep the cooking zone regulator down for another 5-10 seconds and press in firmly once more, before releasing. The flame is now burning.

If at any time the flame does not light successfully, allow about two seconds and repeat the procedure. Press the control knob in slightly longer and possibly a little bit more firmly.

Adjusting the setting:

The maximum and minimum settings are marked on the cooking zone regulators. The flame can be regulated directly.

- Bring to the boil at a high setting if possible and continue simmering at a low setting.

Switching off the cooking zone burners:

- Turn the cooking zone regulator clockwise to zero setting. All cooking zone burners are protected thermoelectrically. If at any time the flame is extinguished unintentionally (e. g. due to pans boiling over or due to a strong draught), the gas supply switches off automatically.

Notes on the right types of saucepan

Using the right types of saucepan will help you to save energy and cut down on cooking times.

Make sure that the diameter of the saucepan base fits the ring.

Place the saucepan onto the ring so that the two fit correctly. The flame should completely cover the area at the bottom of the saucepan, but should not burn round it at the sides.

Ring Diameter of saucepan base

High-speed ring (2.8 kW) 240 - 260 mm

Standard ring (1.9 kW) 200 - 220 mm

Simmering ring* (1.1 kW) approx. 120 mm

*Small pots can also be used using the small pot ring only on the highspeed ring (acc. No. 160).

Always make sure that the lid is on the saucepan.

The food will only boil over if the flame is set too high. With a little practice you will learn to set the flame to just the right heat so that the food will not boil over, even when the lid is on the saucepan.

Please note the safety instructions on page 22!

Selecting the operation mode and the temperature

Selecting the operation mode:

with the oven function (the switch on the left).

Ignite the oven burner and set the

temperature:

with the temperature selection switch (the 2nd switch from the left).

The oven function indicator-electric on the control panel is illuminated when a function has been selected. The oven function indicator-gas on the control panel is illuminated when the oven burner has ignited and goes off about 20 seconds after the burner has been switched off.

Symbols and operation modes

0 Off

Lighting

Must always be set for conventional heating. The Electricity-On lamp will light up in the operation fascia.

Cold circulating air Thawing without heat.

Hot circulating air Makes it possible to work on several levels

at the same time, Cooking at lower temperatures, Simultaneous cooking of various foods. Meat must not be turned. When using hot air, only work with tempera-

tures of up to 200 °C, except for pizza and bread.

Grill Especially suitable for small portions of grilling

food.

The oven is fitted with a thermostat, which controls the temperature only when the oven door is closed and reduces the size of the flame accordingly. If the oven door is open for lengthier periods, the flame automatically gets bigger again. However, when in use always close the oven door with care to prevent the flame being extinguished. The oven burner is protected thermoelectrically. If at any time the flame is extinguished unintentionally the gas supply switches off automatically and the oven function indicator-gas goes out.

The cooling fan can continue to run after the oven has been switched off, that is to say it switches itself back on because of the residual heat!

Ignite the oven burner and set the temperature

The oven burner can be ignited when the oven is either open or closed. The oven burner is ignited by an electric spark. It can also be lit using a match or something similar at the auxiliary lighting port (B) (e. g. in the event of power failure).

- Release the depressed temperature regulator by pressing down.

- Turn the regulator anti-clockwise to 280 °C and press in halfway, until a resistance can be felt. The flame has been ignited.

- Hold the temperature regulator down for another five seconds until the oven function indicator-gas is illuminated.

- Press in the temperature regulator firmly once more, before releasing. The flame is now burning.

- Reset the temperature regulator to the desired temperature. The oven burner continues at maximum setting until the selected temperature has been reached.

If at any time the flame does not light successfully, open the oven door and ventilate, then ignite once more.

Shelving options and equipment

The oven has grids on both sides each with 8 shelf levels. They form the levels 0 to 7.

The level heights are counted from the bottom upwards (see diagram).

On shelving rail 0 a baking tray with pizza or the rack with stone pizza slab can be inserted.

Depending on their use, the rack, the fat-pan or the baking tray can be inserted on shelving rails 1 to 7.

Instructions regarding the shelving levels can be found with their relevant uses and in the guideline value tables.

Do not cover the oven floor with aluminium foil and do not place the baking tray directly on the oven floor. The resulting build-up of heat will impair the baking or roasting results and will damage the enamel.

Gridirons:

Please make sure that the lock-in position of the gridirons always faces the front (towards you).

GEH 640.0 25

Roasting

Use drip pan (accessory) or roasting tray and roasting grid. Roasting grid on the second shelf level from the bottom for meat or drip pan with roasting tray on the first shelf level.

The roasting time depends on the type and the thickness of the meat. Raise the meat slightly when measuring the thickness, as it collapses a little under its own weight. The roasting time for meat with a fatty layer can be as much as double.

Roasting in a pan (oven)

Select hot air convection at a temperature of 180 to 200 °C. You can use any type of pan (enamel-coated steel, cast iron or glass) which does not have plastic handles. We recommend the following procedure:

- Rinse out the pan with water or grease it lightly

- After preparing the meat (adding spices), place it into the pan. Put

the lid on the pan and place the pan onto the rack in the cold oven.

- At the end of the roasting time prepare the gravy in the usual way.

Backing

Do not cover the oven floor with aluminium foil and do not place the baking tray directly on the oven floor.

Baking tins

Always use the middle of the rack. Do not allow anything to jut out over the side. Place rectangular baking tins diagonally on the rack. Always use light-coloured tins for baking.

Baking trays

Lift slightly when removing. When re-inserting, the sloping edge of the trays must face the oven door. Always fully insert the baking trays. Only work on one shelf position when using the upper/lower heat function.

Baking with hot air

Option of baking on several levels. Shelving levels: one tray see baking chart two trays 2. and 6. shelf positions from bottom three trays 1., 4. and 7. shelf positions from bottom. When baking cakes in several trays, add 5 to 10 minutes of cooking time for each tray.

Take out the trays individually according to the degree of browning.

Bake with hot air at 160 °C, if there are no instructions regarding hot air in the recipe.

Important:

Cakes with a moist fruit topping generate a particularly high degree of moisture. A maximum of two cakes should be baked at the same time.

Baking at upper and lower heat

Baking on one level.

Tips:

Should there be no firm instructions for a particular recipe, look at a similar one. At the beginning of the baking process, cooking items that are very different in composition may lead to uneven browning. If this occurs please do not change the temperature setting. Differences in colour rectify themselves during the course of the baking process. Baking moist cakes can produce steam, which forms condensation in the oven. Most escapes through the vapour channel and can collect on kitchen tiles and fronts of units as condensation. This is necessary physically.

Make sure that the appliance and the fascia have cooled down completely before cleaning! Usually it is sufficient to clean the oven with a damp cloth and a little washing-up liquid each time you use it. Wipe dry afterwards.

Do not use any abrasive or aggressive cleaning or scouring agents such as steel wool, soap-impregnated steel wool, metal or plastic sponges or similar agents with an abrasive surface.

Do not use any cleaning agents with a bleaching effect or containing chlorine.

Remove any deposits of calcium or any spots of grease, starch or egg-white as soon as possible. If this is neglected, corrosion can develop under these deposits in stainless steel appliances due to the lack of oxygen.

Food that has boiled over, burnt or become encrusted is best wiped with a damp cloth in the first instance and then removed. Remove substances from glass ceramic hobs with a glass scraper. Remove sugar and melted plastic immediately while the hob is still hot.

Clean the glass ceramic hob after every use.

Thoroughly cleanse the glass ceramic hob once a week. A protective film is formed by thorough cleansing with an appropriate cleansing agent. It will also make daily cleaning easier. Please note the relevant instructions issued by manufacturers of cleansing agents.

Clean the burner covers and the attachments with hot soapy water.

Take care that attachments and burner covers are replaced correctly after cleaning. Engage burner covers by turning.

Installing the cooker into your fitted kitchen

Oven cupboards must be temperature resistant to at least 100 °C. This applies especially to veneers, plastic coatings, adhesives and varnishes. Adjacent cabinetry front must be temperature resistant to at least 70 °C. This film prevents the surfaces from becoming deformed or peeling away, especially on the short sides of the kitchen furniture.

Standard distances in accordance with DIN 68901

Minimum distances between gas cooking zones and flues: 650 mm or according to manufacturer’s instructions.

The back panel and one side of the appliance can be fitted against cupboards or walls of any height. The furniture on the other side of the appliance, however, must be flush with the appliance.

It is essential that the appliance is installed so that it is level.

Preparing the built-in cupboard

In the upper area of the side wall of the cupboard cut out an opening measuring 100 x 100 mm for the supply lines.

Important: Remopve the back wall of the cupboard and the crossbar between the side walls, if applicable!

Cutting out the openings in the worktop

The appliance comes supplied with a template for marking out the opening in the worktop.

Important: Do not mark out the opening in the worktop unless the worktop is already properly fitted.

Place the template against the front edge of the cabinet.

Mark out the opening for the cooker in the worktop and cut out.

Remove transport securing devices.

- The plastic clips used to secure the burner covers during transport are to be removed from all four burners.

- The burner covers and intermediate rings are to be removed from all four burners.

- The two front burners are screwed onto housing sheets to secure them in-transit. Undo the screws.

- The two rear burners are screwed to sheet angles to secure them intransit. Undo the screws. The grating is not needed for the installation of a glass ceramic hob.

Preparing the gas connection

Check that the details on the nameplate (s. p. 30) are the same as the type of gas used in your area. If there are any discrepancies, the hob will have to be converted for the corresponding type or quality of gas (s. p. 34).

Connect the flexible gas safety

hose to the connection points of the hob and screw on tightly so that no gas can escape.
