• The appliance has been designed for a mains supply of 230 V/50 Hz.
• The technical connection data can be found on the rating label of the ap-
pliance.
• Before connecting the appliance it must be checked whether the local sup-
ply conditions (type of gas and gas pressure) and the settings of the ap-
pliance correspond.
• The settings for this appliance are indicated on an indicating label (or on
the identification plate). The settings can also be found in these instructions
in the section „Technical data“ (page 25).
• If a setting is changed, this must be clearly indicated.
• This appliance should not be connected to a pipe for extracting combustion
products. It must be installed and connected in accordance with the appli-
cable conditions of installation. Particular attention should be paid to suf-
ficient ventilation measures.
• All work, such as connection to the gas mains or adjusting and converting
the appliance, should only be carried out by a qualified gas fitter. The legally
recognised regulations and the conditions for connection laid down by the
local gas board should be observed in all details.
• All maintenance and repair work should only be carried out by a qualified
gas fitter trained by the manufacturer. Always ensure to disconnect the ap-
pliance from the energy supply when repairs are being carried out on faci-
lities for directing the flow of gas. Work which has been improperly carried
out endangers the safety of the user!
• If the appliance is run on liquefied petroleum gas (butane or propane gas),
all connections between the bottle and the appliance must be absolutely
tight and leak-proof.
• Do not wedge in freely laid supply hoses or place them on the hot hob.
• Minimum distance to adjacent wall cupboards hung high above the oven
is 650 mm. Please take note of the instructions of the respective manufac-
turer of the cooker hood.
Operation
• This appliance is not meant to be used by persons (including
children) with physical, sensory or mental disabilities, or by
persons with insufficient experience of and/or knowledge about its proper
use, unless supervised by a person responsible for their safety or following
a responsible person's instructions.
• Children should be supervised to ensure that they do not play with this ap-
pliance.
• WARNING: If the surface is cracked, disconnect the appliance from the po-
wer supply in order to rule out the risk of electric shock.
• The appliances must not be cleaned with a steam cleaner.
• Do not switch the appliance on until the installing gas fitter has explained
the appliance to you.
• In addition you should carefully read the information in these operating and
installation instructions. Here you will find important notes concerning safe-
ty and how to use the appliance. You should remember that any damage
due to improper operation does not fall within the scope of the guarantee.
• Only original fittings produced by the manufacturer may be used in order
to ensure safe operation of this hob.
• The appliance is designed solely for the preparation of food in the home.
• Never use the appliance to heat a room.
• In the event of any trouble during operation, immediately turn off the supply
of gas.
• Please keep this manual in a safe place.
• Make sure that the burner covers are replaced correctly. Engage burner co-
vers by turning.
• Do not switch the burner on if not using it for cooking.
• The surfaces of the hob and of the entire appliance become very hot in use.
Always keep children away!
• Overheated fats and oils may spontaneously ignite. Food involving the use
of fats and oils, e.g. chips, may only be cooked under supervision. Never
extinguish ignited fats and oils with water! Put the lid on, turn off the coo-
king zone and remove the pan.
• Always keep pressure cookers under observation until the right pressure
has been reached. First turn the burners of the rings up to maximum flame
and then (following the instructions of the manufacturer of the pressure
cooker) turn the heat down in good time.
• The use of a gas cooker causes heat and humidity to form in the room whe-
re the cooker is installed. Always ensure that the kitchen is wellventilated.
Keep the natural ventilation openings open or provide a mechanical venti-
lation device (e.g. fume extractor hood).
• Intensive and prolonged use of the appliance may require additional venti-
lation, e.g. an open window, or effective ventilation, e.g. operation of the me-
chanical ventilation device at a higher setting.
