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 ventilation system should be only vented to the outside of the building.
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 ventilation system.
Exhaust ducting and connections
–The ducting should be as short and straight as possible, and the number of sharp bends should be minimized.
–For most efficient air extraction, the diameter of the ductwork should not be less than 6" (150 mm)*. Use of flat ducts also reduces the air extraction efficiency.
–Noise levels of the ventilation system will increase if flat ducts or round ducts of less than 6" (150 mm)* in diameter are used.
–Use smooth or flexible pipes made from approved
–Where the ductwork is horizontal, it
must slope away from the ventilation system at least 1/8" per foot (1 cm per meter) to prevent condensation dripping into the appliance.
–If the exhaust is ducted into an unused flue, the air must be expelled parallel to the flow direction of the flue.
