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.
  Intense 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!
The use of a gas cooking appliance results in the production of heat, moisture and products of combustion in the room in which it is installed. Ensure that the kitchen is well ventilated especially when the appliance is in use.

• Prolonged intensive use of the appliance may require additional ventilation, for example the increasing of mechanical ventilation where present, additional ventilation to safely remove the products of combustion to outside (external) air whilst also providing room air changes with additional ventilation.
• Consult a professional before installation of the additional ventilation.

WARNING ‒ Risk of fire!
Leaving fat or oil cooking on an unattended hob can be dangerous and may lead to fires.

• Never leave hot oil or fat unattended.
• Never attempt to extinguish a fire using water; instead, switch off the appliance and then cover with a lid or a fire blanket.

  Hob covers can cause accidents, for example due to overheating, catching fire or materials shattering.
• Do not use hob covers.
  When gas burners are in operation without any cookware placed on them, they can build up a ot of heat. The extractor hood above it may become damaged or catch fire.
• Only operate the gas burners with cookware on them.
  The appliance becomes very hot, fabrics and other objects may ignite.
• Keep fabrics (e.g. garments or curtains) away from the flames.

• Never cover the stainless steel hob, for example with aluminium foil or oven protectors.
• Only use the accessories specified.
  Heat can cause damage to adjacent appliances or kitchen units.
  If the appliance is in operation for an extended period, heat and moisture will be generated.
• Open a window or switch on an extractor hood leading to the outside.
  A build-up of heat may damage the appliance.
• Do not use two burners or heat sources to heat one single item of cookware.
• Do not use griddle plates, clay pots, etc. for a long time 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.
  Acidic liquids, such as lemon juice or vinegar, may damage the surface of the appliance.
• Do not leave acidic liquids on the hob.

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.
  Using 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 there is in the cookware, the more energy that 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.

Disposing of packaging

The packaging materials are environmentally compatible and can be recycled.

• Sort the individual components by type and dispose of them separately.
