Risks during exhaust air operation
WARNING
Risk of suffocation/explosion!
The air in the room where the exhaust
hood is operating is extracted by fan
and released outside. If, in this room, a
fi replace requiring indoor air – such as a
gas fi re or other fuel-based heating sys-
tem – is also in use, the oxygen that is
necessary for combustion may also be
extracted. This can result in the fl ame
being extinguished and gas being re-
leased or the room becoming saturated
with exhaust fumes.
■
It is possible to run the appliance wi-
thout any risk by, for example, provi-
ding non-sealable openings in doors,
windows or ventilation conduits
through which the combustion air
can escape, and by achieving a nega-
tive pressure level in the installation
space of maximum 0.04 mbar. This
prevents the exhaust fumes from
being sucked back into the room.
■
In order to determine the necessa-
ry measures, the entire ventilation
system throughout the home must
be reviewed. Consult the gas safety
consultant who is responsible for the
home.
■
Never attach the exhaust hood to a
ventilation shaft, chimney or smoke-
stack! The air being extracted must
not travel through a channel in which
warm air circulates. The extracted air
may only be released to the outside
through a separate air channel inten-
ded exclusively for the exhaust hood.
NOTICE
Risk of damage to property!
■
For exhaust air operation, a wall or
ceiling break of at least 15.5 cm in
diameter is required.
■
We recommend having a specialist
(electrician) carry out this break (core
drilling).
■
If the exhaust air hose passes through
an exterior wall, the air outlet on the
outside must have a cover with self-
opening slits (not included in the pa-
ckage contents). Hire a specialist to
carry out the wall break.
■
Consider the following: The shorter
and straighter the exhaust hose, the
more powerful the hood function will
be.
■
In Germany, statutory requirements
for extracting exhaust air vary from
state to state. Ask your district chim-
ney sweep for advice.
