Air extraction
–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.
Condensate trap
optional accessory
In some cases, a condensate trap may be required to collect and evaporate any condensation which may develop. This optional accessory is available for ducts 5" (125 mm) and 5 7/8" (150 mm) in diameter.
^When installing a condensate trap, ensure that it is positioned vertically and if possible directly above the exhaust outlet.
