This can be achieved if the combustion air can be replenished by being able to flow through non-closeable openings such as in doors, windows, wall ventilation boxes, or by alternative technical measures such as reciprocally shutting the other device off, etc. An air-intake/exhaust-air wall box by itself is no guarantee that the limiting value will not be exceeded. Note: When assessing the overall requirement, the combined ventilation system for the entire household must be taken into consideration. This rule does not apply to the use of cooking appliances, such as hobs and ovens. All legal requirements concerning the discharge of exhaust air must be observed. Unrestricted operation is possible if the extractor hood is used in recirculating mode – with activated carbon filter. The extractor hood should be fitted with a one-way flap for exhaust-air mode if there is not already one installed in the exhaust-air pipe or wall box. If a one-way flap is not enclosed with the appliance, purchase one from a specialist outlet (see optional accessories on the last page). Attaching the one-way flap . Insert the two lugs on the one-way flap into the holes on the air-pipe connector or air outlet and lock into position. Before installing the one-way flap, ensure that the lettering or stamp is on the outside. Prior to installation Optimum performance of the extractor hood: . Short, smooth extraction pipe. . As few pipe bends as possible. . Largest possible pipe diameter (preferably 150 mm o) and large pipe bends. . Round pipes: We recommend for single-motor model, inner diameter of at least 120 mm for double-motor model. inner diameter of at least 150 mm . Flat ducts must have an inner cross- section equivalent to round pipes which have an inner diameter of 120/150 mm. 120 mm l approx. 113 cm2 150 mm l approx. 177 cm2 . If pipe diameters differ: use sealing strip. . Ensure an adequate air supply for exhaust-air mode. Pipe connection Extractor hoods with 120 mm O air outlet: 100 mm O extraction pipe . Insert the reducing connector (see optional accessories on the last page) into the air-pipe connector and then attach the exhaust-air pipe. 120 mm O extraction pipe . Attach the exhaust-air pipe directly to the air-pipe connector. Extractor hoods with 150 mm O air outlet: 150 mm lextraction pipe . Screw the reducing connector (see optional accessories on the last page) onto the air outlet. . Attach the extraction pipe to the reducing connector. 150 mm lextraction pipe . Attach the exhaust-air pipe directly to the air outlet.. If a one-way flap has been fitted, conduct a performance test. Extractor hoods with rectangular air outlet: . Screw the enclosed air-pipe connector over the air outlet. Recirculated air mode . The air cleaned by an additional activated carbon filter is conveyed back into the room. . In recirculated air mode the exhaust opening must be protected by a grille (see optional accessories on the last page) in order to prevent a mechanical or electric...
