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 material. 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 cooperated 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, the air is extracted from the kitchen and the adjacent rooms. 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.

BOSCH DHL785BAU Extractor Hood - Risk of poisoning

▶ 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 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 roughly every 2  months.
▶ 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 coal-burning) 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 hotplates 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 gas hotplates with cookware on them.
▶ Select the highest fan setting.

WARNING ‒ Risk of burns!
The accessible parts of the appliance become hot during operation.
