Air extraction
WARNING
Danger of toxic fumes.
Gas cooking appliances release carbon monoxide that can be harmful or fatal if inhaled.
To reduce the risk of fire and to properly exhaust air, the exhaust gases extracted by the hood should be vented outside of the building only.
Do not vent exhaust air into spaces within walls or ceilings or in attics, crawl spaces or garages.
To reduce the risk of fire, only use metal ductwork.
Please read and follow the
"IMPORTANT SAFETY INSTRUCTIONS" to reduce the risk of personal injury. Follow all local building codes when installing the hood.
Exhaust ducting and connections
Use smooth or flexible pipework made from approved
To achieve the most efficient air extraction and quietest noise levels, consider the following:
–The diameter of the ductwork should not be less than 6" (150 mm).
–If flat ducting is used, the cross section must not be smaller than the cross section of the ventilation exhaust.
–The ducting should be as short and straight as possible.
–Use ductwork with a wide radius.
–The exhaust duct must not be bent or compressed.
–Make sure all connections are secure.
–Where the ductwork is horizontal, it
must slope away from the hood at least 1/8" per foot (1 cm per meter) to prevent condensation dripping into the appliance.
–If the exhaust is ducted through an outside wall, a Telescopic Wall Vent can be used.
