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.
