Safe use

WARNING ‒ Risk of explosion! Escaping gas may cause an explosion. WHAT TO DO IF YOU SMELL GAS OR IF THERE ARE FAULTS IN THE GAS INSTALLATION

• Immediately shut off the gas supply or close the gas cylinder valve.
• Immediately extinguish all naked flames and cigarettes.
• Do not operate any light switches or appliance switches.
• Do not pull any plugs out of any sockets.
• Do not use any telephones or mobile phones within the building.
• Open windows and ventilate the room.
• Call the after-sales service or the gas supplier.

Escaping gas may cause an explosion. Small amounts of gas can collect over a longer period of time and ignite.

• Close the safety valve for the gas supply when the appliance is out of use for prolonged periods.
• Escaping gas may cause an explosion. If the liquefied gas bottle is not upright, liquefied propane/butane can enter the appliance. In-tense darting flames may therefore escape from the burners. Components may become damaged and start to leak over time so that gas escapes uncontrollably.
• Always use liquefied gas bottles in an upright position.

WARNING ‒ Risk of poisoning!
Using the gas cooking appliance leads to a build-up of heat, moisture, and combustion products in the room where the appliance is installed.

• Ensure that the kitchen is sufficiently ventilated, in particular when operating the gas cooking appliance.
• If the appliance is used intensively and for prolonged periods, ensure that there is additional ventilation so that the combustion products are safely fed to the outside, e.g.if using existing ventilation equipment, set a higher performance level and, at the same time, ensure that the air is replaced with fresh air in the room where the appliance is installed.
• Consult specialist personnel when installing additional ventilation equipment.

WARNING ‒ Risk of fire!

• Leaving fat or oil cooking on an unattended hot can be dangerous and may lead to fires.

• Never leave hot oil or fat unattended.

Preventing material damage

ATTENTION!
Heat can cause damage to adjacent appliances or kit-chen units. If the appliance is in operation for an exten-ded period, heat and moisture will be generated.
Open a window or switch on an extractor hood lead-ing to the outside.

A build-up of heat may damage the appliance.

• Do not use two burners or heat sources to heat onesingle item of cookware.
• Do not use griddle plates, clay pots, etc. for a longtime at full power.

A build-up of heat may damage the controls.

• Do not use a large item of cookware on burners that are close to the control knobs. If a control knob is in the wrong position, this could lead to malfunctions.
• Always turn the control knob to the “Off” position when the appliance is not being used. Handling the cookware roughly may damage the surface of the appliance.
• Handle the cookware on the hob carefully.
• Do not place any heavy objects on the hob.
• Moving the cookware may scratch the glass.
• Lift the cookware when moving it.
• Damage may occur if hard or pointed objects fall on the hob.
• Do not let hard or pointed objects fall onto the hob.
• Do not bump into any of the edges of the hob. Salt, sugar or sand that may fall from the vegetables will scratch the glass.
• Do not use the hob as a work surface or storage space. Melted sugar or food with a high sugar content may damage the glass.
• Remove boiled-over food immediately with a glass scraper.

Environmental protection and saving energy

Saving energy

If you follow these instructions, your appliance will use less energy.
Choose a burner roughly the same size as your pan.
Centre the cookware on the hob.

Tip : Cookware manufacturers often give the upper diameter of the saucepan. It is often larger than the base diameter.

• Unsuitable cookware or incompletely covered cooking zones consume a lot of energy.
  Cover saucepans with suitable lids.

• Cooking without a lid consumes considerably more energy.
  Lift lids as infrequently as possible.

• When you lift the lid, a lot of energy escapes. Use a glass lid.

• You can see into the pan through a glass lid without having to lift it.

Use cookware that is suitable for the quantity of food.

• Large items of cookware containing little food need more energy to heat up.
  Cook with only a little water.

• The more water that is contained in the cookware, the more energy is required to heat it up.
  Turn down to a lower power level early on.

• If you use an ongoing power level that is too high, you will waste energy.

Product Information according (EU) 66/2014 can be found on the attached appliance pass and online on the product page for your appliance.

Disposing of packaging

• The packaging materials are environmentally compatible and can be recycled.
• Sort the individual components by type and dispose of them separately

Escaping gas may ignite.

• If the burner does not ignite after 10 seconds, turn the control knob to the “Off” position and open the door or window in the room. Do not attempt to re-ignite the burner for at least one minute.
• In the event of the burner flames being accidentally extinguished, turn off the burner control. Do not attempt to re-ignite the burner for at least one minute.

ATTENTION!
If you turn the control knob directly between position and 1, malfunctions may occur.
For this reason, never turn directly from position to position 1 or vice versa.

1. Press the control knob for the selected burner and turn it anti-clockwise to the highest level.
   Keep the control knob pressed in. a For all of the burners, sparks are generated and the flame ignites.

2. Wait a few seconds and release the control knob. → “Safety system”, Page 8

3. Turn the control knob to the required position.

4. If the burner does not ignite, turn the control knob to the off position and repeat the steps described above. This time, hold the control knob down for longer (up to 10 seconds).

Note:

• Take the following information into account to ensure that the appliance works correctly:
  The burner parts → Page 7 and the pan supports → Page 7 must be inserted correctly.

• It is important to keep the appliance clean. Cleanthe ignition plugs regularly with a small, non-metallic brush. Take care to prevent the ignition plugs from suffering any heavy knocks.

• The burner holes and grooves must be clean to ensure a correct flame. → “Cleaning the burners”, Page 10

Safety system

The safety system (thermocouple) interrupts the flow of gas if the burners accidentally go out. To ignite the burner, you must activate the system that enables the gas flow.

cookware is made.

Tips

¢   Cooking tips

–    When cooking soups, creams, lentils or chick- peas, add all of the ingredients to the cookware at the same time.

–    For pan-fried dishes, heat the oil up first. As soon as you have started frying, keep the temperature constant and adjust the power level as required. When preparing several portions, wait until the relevant temperature has been reached again. Turn the food regularly.

¢   To reduce the cooking time:

–    Use a pressure cooker to cook creams and pulses. If you are using a pressure cooker, follow the manufacturer’s instructions.

–    The water must be boiling before you add pasta, rice or potatoes. Then adjust the power level in order to continue boiling.

–    Always use a lid when cooking rice and pota-

toes.
