Installation instructions

•

Prior to installation, always follow the

instructions and warnings in the chapter

entitled "Safety instructions"!

Exhaust-air mode

•

The exhaust air is conveyed upwards via a

ventilation shaft or directly through the outer

wall to the exterior.

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 heating

appliances.

•

Before conveying the exhaust air into a non-

functioning smoke or exhaust gas flue, obtain

the consent of the appropriate heating

engineer.

•

Discharge exhaust air in accordance with the

official and statutory regulations (e.g. regional

building laws).

•

If the exhaust air is conveyed through the outer

wall, a telescopic wall box should be used.

To ensure optimum performance, the extractor

hood requires:

–

a short, straight exhaust air pipe and

–

the largest possible pipe diameter.

•

If pipe bends cannot be avoided, ensure the

largest possible radii.

Note: If long, rough exhaust air pipes, a lot of pipe

bends or pipe diameters less than 150 mm are

used, the air capacity will be less than optimum and

there will be an increase in noise.

•

Use only pipes or hoses made of non-

combustible material for installation of the

exhaust air duct.

•

The manufacturer of the extractor hoods is not

responsible for complaints which can be

attributed to planning and design of the

pipework.

Connecting pipes

•

The diameter of the exhaust air pipes should

not be less than 150 mm.

•

Round pipes:

We recommend an inner diameter of 150 mm,

however at least 120 mm.

•

Flat ducts must have the same inner cross-

section as round pipes.

There should be no sharp bends.

Ø 150 mm approx. 177 cm

Ø 120 mm approx. 113 cm

•

If pipe diameters differ:

Use sealing strips.

Connection of 150 mm ø exhaust air pipe

(recommended size)

•

Attach exhaust air pipe

directly to the air-pipe

connector and seal

appropriately. If using an

aluminium pipe, smooth the

connection area beforehand.

Connection of 120 mm ø exhaust air pipe

•

Attach reducing connector

directly to the air-pipe

connector.

•

Attach exhaust air pipe to the

reducing connector.

•

Seal both joints appropriately.
