WARNING
Danger of toxic fumes.
Gas cooking appliances release
carbon monoxide that can be
harmful or fatal if inhaled.
The exhaust gases extracted by
the hood should be vented
outside of the building only.
Do not terminate the exhaust
ducts in attics, garages,
crawlspaces, etc.
To reduce the risk of fire, only use
metal ductwork.
Please read and follow the
"IMPORTANT SAFETY
INSTRUCTIONS"
to reduce the risk of
personal injury. Follow all local building
codes when installing the hood.
Exhaust ducting and connections
– The ducting should be as short and
straight as possible, and the number
of sharp bends should be minimized.
– For most efficient air extraction, the
diameter of the ductwork should not
be less than 6" (150 mm). Use of flat
ducts also reduces the air extraction
efficiency.
– Noise levels of the hood will increase
if flat ducts or round ducts of less
than 6" (150 mm) in diameter are
used.
– Use smooth or flexible pipes made
from approved non-flammable
materials for exhaust ducting.
– Where the ductwork is horizontal, it
must slope away from the hood at
least
1
/
8
" per foot (1cm per meter) to
prevent condensation dripping into
the appliance.
– If the exhaust is ducted through an
outside wall, a Miele Telescopic Wall
Vent can be used.
