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!
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.

3 Environmental protection and saving energy

3.1 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.

3.2 Disposing of packaging

The packaging materials are environmentally compatible and can be recycled.

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

4 Familiarising yourself with your appliance

4.1 Control knob

You can use the control panel to configure all functions of your appliance and to obtain information about the operating status.
You can use the control knobs to set the flame height to different power levels.

4.2 Burner

You can find an overview of the parts of the burner here.

4.3 Pan supports

Insert the pan supports correctly.
Place the cookware correctly on the pan supports.
Never place the cookware directly on the burner.
Always carefully remove the pan supports. When moving a pan support, the pan supports next to it may also move.
Tip: You can remove the metal residue that remains when some items of cookware are moved on the pan support by cleaning it properly.
→ “Cleaning the pan supports”,

5 Accessories

You can buy accessories from the after-sales service, from specialist retailers or online. Only use original accessories, as these have been specifically designed for your appliance.
Accessories vary from one appliance to another. When purchasing accessories, always quote the exact product number (E no.) of your appliance.
