14 Installation Guide - “Cornuchef” RangeSafety requirements BEFORE DELIVERYIn order to be able to install your appliance as soon as it is delivered, you will have to checkthat the layout of your kitchen and your gas and electricity supplies are ready for it.1.1. VentilationIt is essential that the room where the “La Cornue” cooker or hob will be installed hasexcellent ventilation, i.e. to the outside for vapour and burnt gases and a fresh air inlet.Do not use an air recycling system.A flow rate of at least 4 cubic metres per hour of fresh air per kW of gas heat power isnecessary to ensure the supply of combustion air.The gas regulations also require high and low ventilation to be installed in the room wherea gas appliance will be installed.The external ventilation system must consist of fixed aerators or flipping glass panes aswell as vapour aspirators or extractor hoods.We strongly advise you to use an extractor hood.Recommended power:- 700 cubic metres per hour or 10 – 15 times the volume of the air in the roomeach hour."La Cornue" can propose you models of customized hoods in materials matching yourcooker or extractors that can be integrated into a hood manufactured by the user.The ventilation hood has to be built with inflammable materials.For optimum efficiency, the fresh air inlet for renewing the air extracted by the hood mustbe located either directly at the back of the appliance or within a 2 – 3m. radius, at groundlevel.1.2. Installation (see following page)As the oven and the hob are particularly well insulated, the appliance can be built-inwithout any need for any special precautions with regard to the surroundings. However,if the cooker or the hob is installed against a wall, the hottest parts (the strip between 60and 95cm. from the floor, and the surface between the hob and the extractor hood) mustbe protected with a stainless steel plate (credenza) or ceramic tiles.Ceramic cardboard with a minimum thickness of 20mm. must be installed underthe hob to insulate the units placed underneath.1.
