Never connect an exhaust hood to
an active chimney, dryer vent, vent
flue, or room venting ductwork. Seek
professional advice before connect
-
ing an exhaust hood vent to an exist
-
ing, inactive chimney or vent flue.
Ductwork with a diameter of less
than 6" (150 mm) should only be
used when absolutely necessary. As
duct diameter decreases, the hood’s
performance and sound levels will
be affected.
Important:
If the ductwork runs through rooms,
ceilings, garages, etc. where tempera-
ture variations exist, it may need to be
insulated to reduce condensation. In
some cases, a condensate trap may
also be required to collect and evapo-
rate any condensate which may occur.
When installing a condensate trap,
ensure that it is positioned vertically
and if possible directly above the ex
-
haust outlet.
