Planning notes Depending on the type of installation (surface-mounted or flush-mounted, with or without an appliance cover), the specific location of the cut-out and the knob positions may vary.The drawing "Installation of the control knob" must be observed if the panel is more than 23 mm thick (there must be a recess at the rear).If installing with the appliance cover VA 440 or filler strip VA 450 take into account the additional space required for the depth.If combining several appliances with at least one appliance cover, the filler strip VA 450 is required to compensate for the depth of the appliance without the appliance cover.If combining several Vario appliances of the 400 series, a connection strip VA 420 must be placed between the appliances. Depending on the type of installation, the corresponding connection strip must be provided.In the cut-out, the installation system requires the side edge to be at least 1/2" for surface mounting and at least 3/8" mm for flush mounting. Ensure a continuous cut surface of 90(degree).The bearing capacity and stability, in the case of thin worktops in particular, must be supported using suitable substructures. Take into account the appliance weight and additional loads.Additional instructions for flush mounting:Installation is possible in worktops made of stone, synthetics or solid wood. Heat resistance and watertight sealing of the cut edges must be observed. Concerning other materials please consult the worktop manufacturer.The groove must be continuous and even, so that uniform placing of the appliance on the gasket is ensured. Do not use discontinuous lining.The joint width may vary due to size tolerances of the combinations and of the worktop cut-out.If installing several appliances in individual cut-outs allow for a minimum distance of 2" between the cooktops.Special nozzles can be ordered as spare parts.Plan for an electrical connection (the appliance is not operable without power supply).Air intake from above.No intermediate shelf required.Rear panel and wall trims must be heat-resistant and consist of a non-flammable material.A minimum clearance of at least 150 mm from adjacent heat-sensitive furniture or contact surfaces must be observed or thermal insulation fitted.If operated next to the downdraft ventilation VL 414, the air baffle AA 414 is recommended to ensure maximum performance of the cooktop.Appliance can be snapped into the countertop from above.
