– 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, flue,
or room venting ductwork. Seek
professional advice before
connecting an exhaust hood vent to
an existing, inactive chimney or vent
flue.
Important!
If the ductwork runs through rooms,
ceilings, garages, etc. where
temperature variations exist, it may
need to be insulated to reduce
condensation.
