Important safety information

Read these instructions carefully. Only then will you be able to 

operate your appliance safely and correctly. Retain the 

instruction manual and installation instructions for future use or 

for subsequent owners.

The appliance can only be used safely if it is correctly installed 

according to the safety instructions. The installer is responsible 

for ensuring that the appliance works perfectly at its installation 

location.

The width of the extractor hood must correspond at least with 

the width of the hob.

For the installation, observe the currently valid building 

regulations and the regulations of the local electricity and gas 

suppliers.

Danger of death!

Risk of poisoning from flue gases that are drawn back in.

Always ensure adequate fresh air in the room if the appliance is 

being operated in exhaust air mode at the same time as room 

air-dependent heat-producing appliance is being operated.

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.

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!

■

Operating several gas burners at the same time gives rise to a 

great deal of heat. The ventilation appliance may become 

damaged or catch fire. The ventilation appliance must only be 

combined with gas burners that do not exceed the maximum 

total output of 12.4 kW.

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 mm. 

Risk of injury!

■

Components inside the appliance may have sharp edges. 

Wear protective gloves.

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.

Danger of suffocation!

Packaging material is dangerous to children. Never allow 

children to play with packaging material.

Risk of tipping!

The appliance is very narrow and can tip over easily. Do not set 

the appliance on an uneven surface. Set the appliance flat on 

the surface.

General information

Exhaust air mode

Note: 

The exhaust air must not be conveyed into a functioning 

smoke or exhaust gas flue or into a shaft which is used to 

ventilate installation rooms which contain heat-producing 

appliances.

■

Before conveying the exhaust air into a non-functioning smoke 

or exhaust gas flue, obtain the consent of the heating 

engineer responsible.

■

If the exhaust air is conveyed through the outer wall, a 

telescopic wall box should be used.

Exhaust duct

Note: 

The appliance manufacturer does not assume any 

warranty for complaints attributable to the pipe section.

■

The appliance achieves its optimum performance by means of 

a short, straight exhaust air pipe and as large a pipe diameter 

as possible.

■

Because of long rough exhaust air pipes, many of which are 

pipe bends or have diameters smaller than 150 mm, the 

optimum extraction performance is not achieved and fan 

noise is increased.

■

The pipes or hoses for laying the exhaust duct must consist of 

non-combustible material.

Round pipes

An inner diameter of 150 mm, but at least 120 mm, is 

recommended.

Flat ducts

The inner cross-section must correspond to the diameter of the 

round pipes.

Ø 150 mm approx. 177 cm

2

Ø 120 mm approx. 113 cm

2

■

Flat ducts should have no sharp deflections.

■

Use sealing strip for deviating pipe diameters.

Gas hob

The appliance can be used in conjunction with a gas hob.

Caution!

The gas hob must not exceed the following values:

■

Total maximum output: 12.4 kW

■

Maximum output for a single burner: 5 kW

■

Maximum of 5 single burners

Electrical connection

: 

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.

Check the indoor installation before connecting the appliance. 

Ensure that the indoor installation is sufficiently fused. The 

voltage and frequency of the appliance must correspond to that 

of the electrical installation (see rating plate).

The appliance corresponds to protection class I and must only 

be operated with a protective earth connection.

An all-pole isolating switch with at least a 3 mm contact gap 

must be fitted in the installation. The plug must still be 

accessible after installation.

Only a qualified electrician who takes the appropriate 

regulations into account may install or replace the connecting 

cable.
