Do not let children play with the appliance.
Children must not perform cleaning or user maintenance unless they are at least 15 years old and are being supervised.
Keep children under the age of 8 years away from the appliance and power cable.

1.4 Safe use
WARNING  ‒ Risk of suffocation!
Children may put packaging material over their heads or wrap themselves up in it and suffocate.

• Keep packaging material away from children.

• Do not let children play with packaging ma- terial.
  Children may breathe in or swallow small parts, causing them to suffocate.

• Keep small parts away from children.

• Do not let children play with small parts.

WARNING  ‒ Risk of poisoning!
Risk of poisoning from flue gases being drawn back in. Room-air-dependent heat-producing appliances (e.g. gas, oil, wood or coaloperated heaters, continuous flow heaters or water heaters) obtain combustion air from the
room in which they are installed and discharge the exhaust gases into the open
through an exhaust gas system (e.g. a chimney). With the extractor hood switched on, air
is extracted from the kitchen and the  adjacentrooms. Without an adequate supply of air,  the air pressure falls below atmospheric pressure.
Toxic gases from the flue or the extraction shaft are sucked back into the living space.

• Always ensure adequate fresh air in the room if the appliance is being operated in exhaust air mode at the same time as a room-air-dependent heat-producing appliance is being operated.
• It is only possible to safely operate the appliance if the pressure in the room in which the heating appliance is installed does not drop more than 4 Pa (0.04 mbar) below atmospheric pressure. This can be achieved whenever the air needed for combustion is able to enter through openings that cannot be sealed, for example in doors, windows, incoming/exhaust air wall boxes or by other technical means. An incoming/exhaust air wall box alone does not ensure compliance with the limit.
• In any case, consult your responsible chimney sweep. They are able to assess the house’s entire ventilation setup and will suggest the suitable ventilation measures to you.
• Unrestricted operation is possible if the appliance is operated exclusively in circulating-air mode.

WARNING ‒ Risk of fire!
Fatty deposits in the grease filters may catch fire.

• Never operate the appliance without a grease filter.
• Clean the grease filters regularly.
• Never work with naked flames close to the appliance (e.g. flambéing).
• Do not install the appliance near a solid fuel heating appliance (e.g. wood- or coalburning) unless the heating appliance has a sealed, non-removable cover. There must be no flying sparks. Hot oil or grease ignites very quickly.
• Always supervise hot oil and fat.
• Never extinguish burning oil or fat with water. Switch off the cooking zone. Extinguish flames carefully using a lid, fire blanket or something similar. When gas burners are in operation without any cookware placed on them, they can build up a lot of heat. A ventilation appliance installed above the cooker may become damaged or catch fire.
• Only operate the gas burners with cookware on them. Operating multiple gas hobs at the same time generates a great deal of heat. A ventilation appliance installed above the cooker may become damaged or catch fire.
• Only operate the gas hobs with cookware on them.
• Select the highest fan setting.
• Never operate two gas hobs simultaneously on the highest flame for longer than 15 minutes. Two gas hobs correspond to one large burner.
• Never operate large burners of more than 5  kW with the highest flame for longer than 15 minutes, e.g. a wok.
