Air venting 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. The exhaust air adapter of the ventilation hood depends on the blower used: - DRIB/DREB XL: 8" (203 mm) - DRIB/DREB XXL: 10" (254 mm) Only use smooth pipes or flexible duct hoses made from noncombustible materials for exhaust duct. To achieve the greatest possible air extraction with the lowest noise levels, please observe the following: - The cross-section of the exhaust duct must not be smaller than the cross-section of the vent collar (see appliance dimensions). - The exhaust duct should be as short and straight as possible. - If elbows are needed, make sure they have a large radius. - The exhaust duct must not be kinked or compressed. When selecting the exhaust duct, ensure that it is rigid enough to retain its shape during operation. - Make sure that all connections are secure and airtight. Any constriction of the airflow will reduce extraction performance and increase operating noise.  If the exhaust air is to be ducted into a flue, the duct must be directed in the flow direction of the flue. 34
