Room air-dependent heat-producing
appliances (e.g. gas, oil, wood or coal-
operated 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 air through an exhaust gas system
(e.g. a chimney).
In combination with an activated vapour
extractor hood, room air is extracted from
the kitchen and neighbouring rooms - a
partial vacuum is produced if not enough
fresh air is supplied. Toxic gases from the
chimney or the extraction shaft are sucked
back into the living space.
■
Adequate incoming air must therefore
always be ensured.
■
An incoming/exhaust air wall box alone
will not ensure compliance with the limit.
Safe operation is possible only when the
partial vacuum in the place where the heat-
producing appliance is installed does not
exceed 4 Pa (0.04 mbar). This can be
achieved when 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.
In any case, consult your responsible
Master Chimney Sweep. He is able to
assess the house's entire ventilation setup
and will suggest the suitable ventilation
measures to you.
Unrestricted operation is possible if the
vapour extractor hood is operated
exclusively in the circulating-air mode.
Risk of fire!
■
Grease deposits in the grease filter may
catch fire.
Clean the grease filter at least every
2 months.
Never operate the appliance without the
grease filter.
Risk of fire!
■
Grease deposits in the grease filter may
catch fire. Never work with naked flames
close to the appliance (e.g. flambéing). Do
not install the appliance near a heat-
producing appliance for solid fuel (e.g.
wood or coal) unless a closed, non-
removable cover is available. There must
be no flying sparks.
Risk of fire!
■
Hot oil and fat can ignite very quickly.
Never leave hot fat or oil unattended.
Never use water to put out burning oil or
fat. Switch off the hotplate. Extinguish
flames carefully using a lid, fire blanket or
something similar.
Risk of fire!
■
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.
Risk of fire!
■
Operating several gas burners at the
same time gives rise to a great deal of
heat. A ventilation appliance installed
above the cooker may become damaged
or catch fire. Never operate two gas
burners simultaneously on the highest
flame for longer than 15 minutes. One
large burner of more than 5 kW (wok) is
equivalent to the power of two gas
burners.
Risk of burns!
The accessible parts become very hot when
in operation. Never touch hot parts. Keep
children at a safe distance.
Risk of injury!
■
Components inside the appliance may
have sharp edges. Wear protective gloves.
Risk of injury!
■
Items placed on the appliance may fall
down. Do not place any objects on the
appliance.
