RISK OF FIRE
Grease deposits in the grease filter can catch fire. 

The given safety clearance must be observed to 

avoid heat buildup. Observe the specifications for 

your cooking appliance. If gas and electric cooktops 

are used together, the largest given clearance 

applies.
The appliance may only be installed directly next to 

a cabinet or wall on one side. The wall or cabinet 

clearance must be at least 2" (50 mm). 

The clearance between the shelf on the cooktop and the 

bottom of the extractor hood may not be less than 24" 

(610 mm) in the case of electric cooktops and 30" (760 

mm) in case of gas or combined ranges.
If the installation instructions for the gas cooking 

appliance specify a larger distance, this must be taken 

into account.
Electric cooktop

Note:  Ventilation may not exit through an already 

operational smoke or exhaust chimney, nor a duct used 

for ventilating furnace installation areas.

▯

If the ventilation is intended to pass through a smoke 

or exhaust that is not in operation, the responsible 

area heating inspector must give approval.

▯

If the ventilation passes through an external wall, use a 

telescope wall sleeve.

Note:  The device manufacturer does not assume any 

warranty for complaints attributable to the pipe section.

▯

The ventilation opening and the exhaust air ducts must 

be made according to the local circumstances.

▯

The device achieves its optimum performance by 

means of a short, straight exhaust air pipe and as 

large a pipe diameter as possible.

▯

As a result of long rough exhaust air pipes, many pipe 

bends or too-small diameters, the optimum extraction 

performance is not achieved and fan noise is 

increased.

▯

The pipes or hoses for laying the exhaust air line must 

consist of non-combustible material.

▯

Smooth the connection area of the pipes before 

installation.

▯

Seal the connection points of the pipes appropriately.

Round pipes
An inner diameter of Ø 8" (200 mm) is recommended.
Flat ducts
The inner cross-section must correspond to the diameter 

of the round pipes.
Ø 8" (200 mm) approx. 50.3 inches

2

 (324 cm

2

)

▯

Flat ducts should have no sharp deflections.

▯

Use sealing strip for deviating pipe diameters.

▯

The wall must be level, vertical and adequately load-

bearing.

▯

The depth of the bore holes must be the same length 

as the screws. The wall plugs must have a secure grip.

▯

The enclosed screws and wall plugs are suitable for 

solid brickwork. Suitable fasteners must be used for 

other structures.
