Safety
fire or other fuel-based heating system –
is also in use, the oxygen that is neces-
sary for combustion may also be extrac-
ted. This can result in the flame being ex-
tinguished and gas being released or the
room becoming saturated with exhaust
fumes.
There must be adequate room ventila-
n
tion if the exhaust hood is operated
simultaneously with appliances that
burn gas or other fuels (does not apply
to appliances that only recirculate air
into the room).
It is possible to run the appliance
n
without any risk by, for example,
providing non-sealable openings in
doors, windows or ventilation conduits
through which the combustion air can
escape, and by achieving a negative
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 necessary
n
measures, the entire ventilation sys-
tem throughout the home must be re-
viewed. Consult the gas safety con-
sultant who is responsible for the
home.
Do not route the exhaust air into a
n
chimney used for exhaust gases from
appliances that run on gas or other
fuels (does not apply to appliances
that only recirculate the air into the
room).
Never attach the exhaust hood to a
n
ventilation shaft, chimney or
smokestack! The air being extracted
must not travel through a channel in
which warm air circulates. The extrac-
ted air may only be released to the
outside through a separate air channel
intended exclusively for the exhaust
hood.
NOTICE
Risk of damage to property!
Improper handling of the appliance can
lead to damage to property.
To operate the air extraction, a wall or
n
ceiling break of at least 15.5 cm in dia-
meter is required.
We recommend having a specialist
n
(electrician) carry out this break (core
drilling).
If the exhaust air hose passes through
n
an exterior wall, the air outlet on the
outside must have a cover with self-
opening slits (not included in the pack-
age contents). Hire a specialist to
carry out the wall break.
Consider the following: The shorter
n
and straighter the exhaust hose, the
more powerful the hood function will
be.
Be aware that when discharging the
n
exhaust air, official regulations must
be observed, which may vary from
one German state to the next. Ask
your district chimney sweep for ad-
vice.
