Air suction in interior,
fl
ue extraction through facade. The outlet opening must
be at least 500 away from facade and in
fl
ammable objects.
Air suction in interior,
fl
ue extraction through facade. The outlet opening must
be at least 500 away from facade and in
fl
ammable objects. Flue extraction duct
must be longer by at least 300 mm and from suction inlet to avoid spurious
fl
ue
suction into interior. Connection to the hot air unit is via a coaxial inlet, such as for
installation of the unit on the pivoted bracket.
Air suction and
fl
ue extraction through facade. Minimum distance of the
fl
ue
extraction outlet from facade and in
fl
ammable objects is 500 m. Flue extraction
duct must be longer by at least 300 mm and from suction inlet to avoid spurious
fl
ue suction into interior.
Air suction and
fl
ue extraction through roof. The outlet must be at least 1,000
mm away from roof surface and in
fl
ammable objects. Connection to the hot air
unit is via a coaxial inlet, such as for installation of the unit on the pivoted bracket.
