Installation Installation recommendations - We also recommend a distance of at least 25 1/2" (650 mm) above electric cooktops to provide more workspace and easier cooking under the hood. - When selecting an installation height, always take the user height into consideration. Users should have ample space to work comfortably on the cooktop and reach the ventilation hood controls with ease. - Please note that the greater the distance from the cooktop, the less effective the hood is at drawing in the cooking vapors. - To achieve optimal vapor extraction, make sure that the hood covers the cooktop. The hood should be positioned centrally over the cooktop, not to the side or rear. - The cooktop should be no wider than the hood. Preferably, it should be narrower. - The mounting area must be easily accessible. The ventilation hood should be easy to reach and disassemble in case a service call is necessary. This should be taken into consideration when planning the position of cupboards, shelves, ceilings or decorative elements in the vicinity of the ventilation hood. Drilling diagram for wall mounting  When drilling, please follow the directions contained on the accompanying installation sheet.  When installing a custom back wall with pre-drilled holes, please refer to the drilling distances in the drawing above (screws  3/16" (5 mm)). * The dimension for the middle wall bracket is variable. It will depend on the position of the wall vent and the socket. It should be set as low as possible. 29
