information
Important safety information
:Warning – Risk of deflagration!
Accumulation of unburned gas in an enclosed
area carries a risk of deflagration. Do not
subject the appliance to draughts. These
might blow out the burners. Carefully read the
instructions and warnings on the operation of
gas burners.
:Warning – Risk of poisoning!
The kitchen will become hot and humid and
combustion products produced when this gas
appliance is used. Make sure the kitchen is
well ventilated, particularly when the hob is in
operation: either keep the natural ventilation
apertures open, or install a ventilation system
(extractor hood). Intense prolonged use of the
appliance may require additional or more
effective ventilation: open a window or
increase the power of the ventilation system.
:Warning – Risk of burns!
■ The hotplates and their immediate vicinity
get very hot. Never touch the hot surfaces.
Keep children under 8 years old well away
from this appliance.
Risk of burns!
■ 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. Both can cause burns.
Always use liquefied gas bottles in an
upright position.
:Warning – Risk of fire!
■ The hotplates get very hot. Do not rest
inflammable objects on the hob. Do not
store objects on the hob.

inflammable materials or non-food products
below or near this domestic appliance.
Risk of fire!
■ Fat or oil which is overheated can catch fire
easily. Never leave fat or oil to heat up
unattended. If oil or fats do catch fire, never
use water to put the fire out. Put the fire out
by covering the pan with a lid and switch off
the hotplate.
