Exhaust-air mode

Ø
150
The exhaust air is discharged upwards
through a ventilation shaft or directly through
the outside wall into the open.
For operating in exhaust-air mode, a one-
way flap should be mounted inside the wall
ventilation box.
If no one-way flap was enclosed with the
hood, it can be obtained from a specialist
retailer.
Installing the one-way flap:
❑ Snap the one-way flap into the air pipe.
The two lightly sprung flaps must be
able to move upwards.
If the exhaust air is going to be
discharged into the open, a telescopic wall
box should be fitted into the outside wall.
❑ For optimum extractor hood efficiency:
❑ Short, smooth air exhaust pipe.
❑ As few bends in the pipe as possible.
❑ Diameter of pipe to be as large as
possible and no tight bends in pipe.
If long, rough exhaust-air pipes, many
pipe bends or smaller pipe diameters
are used, the air extraction rate will no
longer be at an optimum level and

there will be an increase in noise.
❑ Round pipes:
We recommend Internal diameter:
120 mm
❑ Flat ducts must have an internal cross
section that equates to that of round
pipes.
There should be no sharp bends.
Ø 150 mm approx. 177 cm
❑ If pipes have different diameters:
Insert sealing strip.
❑ For exhaust-air mode, ensure that there
is an adequate supply of fresh air.
Connecting a Ø 150 mm exhaust-air pipe:
❑ Mount the pipe directly onto the air outlet
on the hood.
