  • a maximum of 0.5 W when the appliance is in operation with the display switched off

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 pots and pans with flat bases.

  • Uneven bases increase energy consumption.

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.

    Hot steam may escape when you open the appliance door. Steam may not be visible, depending on the temperature.
    ▶ Open the appliance door carefully.
    ▶ Keep children at a safe distance.
    When the dish is ready, switch off the appliance.

19.2 Condensation
This section tells you how condensation is formed, how you can prevent damage, and how you can prevent condensation from forming.
When you are cooking food in the cooking compartment, a lot of steam may form in the cooking compartment. Since your appliance is extremely energy- efficient, only a small amount of heat escapes during operation. Due to the significant differences in temperature between the appliance interior and the external parts of the appliance, condensation may build up on the appliance door, the control panel or the front panels of adjacent kitchen cabinets. The formation of condensation is a normal physical phenomenon. In order to prevent damage, wipe away the condensation. When you preheat the appliance, you reduce the buildup of condensation.

19.3 Cooking tips
Observe this information when preparing food.

  • The temperature and cooking time depend on the amount of food and the recipe. Settings ranges are specified for this reason. Select the lower value first.

  • The setting values apply to food placed in the cooking compartment while the cooking compartment is still cold.
    Do not place accessories into the cooking compartment until it has finished preheating.

  • Remove any accessories that are not being used from the cooking compartment.

  • Ensure that the accessory slides in the right way round.

Reference gases
Unsuitable gas mixtures may impair the cooking power level.
Note: The appliance was manufactured in accordance with the reference gases specified in the standards. If you use gas that does not correspond to the specified gas mixture and gas pressure, under certain circumstances, the power level and the heat output do not deliver the desired result.

Gas designation Gas mixture in %
G20 CH4=100
G25 CH4=86, N2=14
G30 n-CH4=50, i-CH10=50

19.4 Initial baking
When baking, use the shelf positions indicated.
By burning the gas from the lower burner, heat is distributed in the oven. For this reason, the base of the food is baked better.

19.5 Roasting and grilling

The setting values are based on the assumption that unstuffed, chilled, ready- to-roast poultry, meat or fish is placed into a cold cooking compartment.

  •  Turn the poultry, meat or fish after approx. 1/2 to 2/3 of the time listed.
  • When you turn poultry, ensure that the breast side or skin side is underneath to begin with.
  • Use tongs to turn the pieces of food you are grilling. If you pierce the meat with a fork, the juices will run out and it will become dry.
  • Only add salt to steaks once they have been grilled. Salt draws water from the meat.

Roasting and grilling on the wire rack
Roasting on the wire rack works particularly well for large poultry or for multiple pieces at the same time.

  • Depending on the size and type of the food to be roasted, add up to 1/2 litre water to the universal pan.
    You can make a sauce from the juices that are collected. This also means that less smoke is produced and the cooking compartment does not become as dirty.

  • Use the protecting plate with the gas grill.
    The gas grill cannot be used without the protecting plate.

  • Place the food to be grilled on the wire rack. In addition, slide the universal pan in at least one shelf position lower, with the slanted edge facing the appliance door. This means that any dripping fat is caught.
