Risks during exhaust air operation
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
without any risk by, for example,
providing non-sealable openings in
doors, windows or ventilation con-
duits through which the combustion
air can escape, and by achieving a
negative pressure level in the instal-
lation spaceof maximum 0.04 mbar.
This prevents the exhaust fumes from
being sucked back into the room.
■
In order to determine the necessary
measures, the entire ventilation sys-
tem throughout the home must be
reviewed. Consult the gas safety con-
sultant 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 out-
side through a separate air channel
intended 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 di-
ameter 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 out-
let on the outside must have a cover
with self-opening slits (not included
in the package contents). Have this
installed by the same specialist that
is carrying out the wall break.
■
Please note: The shorter and straight-
er the exhaust hose, the more power-
ful the Exhaust hood function will be.
■
In Germany, statutory requirements
for extracting exhaust air vary from
state to state.
Consult a gas safety consultant.
