manual abstract
in Germany: Technische Regeln Gasinstallation TRGI). Always comply with the currently valid regulations and installation instructions supplied by the gas appliance manufacturer. Only one side of the extractor hood may be installed next to a high-sided unit or high wall. Gap at least 50 mm. Minimum distance on gas hotplates between the upper edge of the trivet and lower edge of the extractor hood: 650 mm, Fig. 1. Prior to installation Exhaust-air mode 150 150 The exhaust air is discharged upwards through a ventilation shaft or directly through the outside wall into the open. DExhaust air should neither be directed into a smoke or exhaust flue that is currently used for other purposes, nor into a shaft that is used for ventilating rooms in which stoves or fireplaces are also located. Exhaust air may be discharged in accordance with official and statutory regulations only (e.g. national building regulations). Local authority regulations must be observed when discharging air into smoke or exhaust flues that are not otherwise in use. DWhen the extractor hood is operated in exhaust-air mode simultaneously with a different burner which also makes use of the same chimney (such as gas, oil or coal-fired heaters, continuous-flow heaters, hot-water boilers) care must be taken to ensure that there is an adequate supply of fresh air which will be needed by the burner for combustion. Safe operation is possible provided that the underpressure in the room where the burner is installed does not exceed 4 Pa (0.04 mbar). This can be achieved if combustion air can flow through non-lockable openings, e.g. in doors, windows and via the airintake/ exhaust-air wall box or by other technical measures, such as reciprocal interlocking, etc. If the air intake is inadequate, there is a risk of poisoning from combustion gases which are drawn back into the room. 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. Unrestricted operation is possible if the extractor hood is used in recirculating mode – with activated carbon filter. Prior to installation For operating in exhaust-air mode, a one-way flap should be mounted inside the extractor hood unless there is already one fitted in the outlet duct or wall ventilation box. If no one-way flap was enclosed with the hood, it can be obtained from a specialist retailer. 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. If the exhaust air is going to be discharged into the open, a telescopic wall box should be fitted into the outside wall. For optimum extractor hood efficiency: . Short, smooth air exhaust pipe. . As few bends in the pipe as possible. . Diameter of pipe to be as large as possible and no tight bends in pipe. If long, rough exhaust-air pipes, many pipe bends or smaller pipe diameters are used, the air extraction rate will no longer be at an optimum level and there will be an increase in noise. . Round pipes: We recommend Internal diameter: 150 mm. . Flat ducts must have an internal cross- section that equates to that of round pipes. There should be no sharp bends. l150 mm approx. 177 cm2 . If pipes have different diameters: Insert sealing strip. . For exhaust-air mode, ensure that there is an adequate supply of fresh air. Pipe connection . Screw the enclosed air-pipe connector over the air outlet. 1...
