Air extraction Condensate trap optional accessory - If the exhaust is ducted into an inactive flue, the air must be expelled parallel to the flow direction of the flue. In some cases, a condensate trap may also be required to collect and evaporate any condensate which may occur. This optional accessory is available for ducts 5" (125 mm) and 6" (150 mm) in diameter. 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. When installing a condensate trap, ensure that it is positioned vertically and if possible directly above the exhaust outlet. 35
