Room air dependent heat producing

en    Important safety information


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 


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 


Unrestricted operation is possible if the vapour 

extractor hood is operated exclusively in the 

circulating-air mode.



Danger of death!

Risk of poisoning from flue gases that are 

drawn back in. If installing a ventilation system 

in a room with a heat-producing appliance 

connected to a chimney/flue, the electricity 

supply to the hood must be equipped with a 

suitable safety switch.



Risk of fire!

Grease deposits in the grease filter may catch 

fire. The specified safety distances must be 

observed in order to prevent an accumulation 

of heat. Observe the specifications for your 

cooking appliance. If gas and electric hobs 

are operated together, the largest specified 

distance applies.

Only one side of the appliance may be 

installed directly next to a high-sided unit or a 

wall. The distance between the appliance and 

wall or high-sided unit must be at least 50 




Risk of injury!

Components inside the appliance may have 

sharp edges. Wear protective gloves.

Risk of injury!

The appliance may fall down if it has not 

been properly fastened in place. All 

fastening components must be fixed firmly 

and securely.

Risk of injury!

The appliance is heavy. To move the 

appliance, 2 people are required. Use only 

suitable tools and equipment.



Risk of electric shock!

Components inside the appliance may have 

sharp edges. These may damage the 

connecting cable. Do not kink or pinch the 

connecting cable during installation.



Risk of electric shock!

It must always be possible to disconnect the 

appliance from the electricity supply. The 

appliance must only be connected to a 

protective contact socket which has been 

correctly installed. If the plug is no longer 

accessible following installation of the 

appliance, or a fixed connection is required, 

an all-pole isolating switch must be present on 

the installation side with a contact gap of at 

least 3 mm. The fixed connection must only be 

installed by an electrician.



Danger of suffocation!

Packaging material is dangerous to children. 

Never allow children to play with packaging
