– If the exhaust is ducted into an inac-
tive flue, the air must be expelled
parallel to the flow direction of the
flue.
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.

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
exhaust outlet.
