Air extraction

Danger of toxic fumes.

Please heed the ,,Warning and

Safety Instructions" to avoid the

dangers of toxic fumes.

The cooker hood should be in-

stalled according to local building

regulations. Seek approval from the

building inspector where necessary.

Connection for extraction

– The extraction ducting should be as

short and straight as possible.

– To ensure efficient air extraction the

diameter of the exhaust ducting

should not be less than 125 mm (5").

The use of flat ducting also reduces

the air extraction efficiency.

– The use of exhaust ducting with a

diameter less than 125 mm (5") and

flat ducting increases the noise level

of the cooker hood.

– Only use wide radius bends. Tight

bends reduce the air throughput of

the cooker hood.

– Only use smooth or flexible pipes

made from non-flammable materials

for exhaust connection.

– Where ducting is horizontal, it must

be laid to slope away at 1 cm per

metre (1/8" per foot) , to ensure no

condensation drains into the ap-

pliance.

– If the exhaust air is to be ducted out-

side, the installation of a Miele tele-

scopic wall vent is recommended.

– If the exhaust air is to be ducted into

a vent flue, the ducting must be di-

rected in the flow direction of the flue.

Connection

Only use narrower diameter pipe-

work where it is unavoidable, for

example where existing pipework

has to be used.

The narrower the diameter the lower

the performance and the noisier the

operation.

If a connection to 100 mm (4")

diameter piping is to be made, fit the

reducer supplied (adaptor) on to the

exhaust connection of the cooker

hood.
