– If the exhaust is ducted into an
inactive 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
connecting an exhaust hood vent to
an existing, inactive chimney or vent
flue.
Condensate trap
Important:
If the ductwork runs through rooms,
ceilings, garages, etc. where
temperature variations exist, it may
need to be insulated to reduce
condensation. In some cases, a
condensate trap may also be required
to collect and evaporate any
condensate which may occur.
When installing a condensate trap,
ensure that it is positioned vertically
and if possible directly above the
exhaust outlet.
