Instruction for the Installerl The side walls of the unit in which the hob isgoing to be installed, must not exceed the heightof the working top.l Avoid installing the appliance in the proximity ofinflammable materials (e.g. curtains, tea towelsetc.).l The following instructions about installation andmaintenance must be carried out by qualifiedpersonnel in compliance with the regulation inforce. The regulation to be applied for this type ofinstallation is NBN D 5I.003 : "Installationsfunctioning with combustible gas lighter thanair".l The appliance must be electrically disconnectedbefore all interventions. If any electric supply tothe appliance is required to carry out the work,ensure all the necessary precautions arefollowed.GAS CONNECTIONIt is indispensible that the connection to the gas mainsare carried out by means of an AGB tap. Choose fixedconnections or use a flexible pipe in AGB (stainlesssteel).If using flexible metallic pipes, be careful they do notcome in contact with mobile parts or they are notsqueezed. Use the same attention when the hob iscombinated with an oven.This hob can be operated by Slochteren gas (G25) witha nominal pressure of 25 mbar or by natural gas withnominal pressure of 20 mbar. No regulation is requiredfor use by these two types of gas.Before fitting the appliance ensure that the installationhas the correct voltage for the appliance. At full capacity,the drop in pressure must not exceed 5%. Such a dropin pressure is caused by the following parameters:- maximum capacity of meter;- diameter and lenght of the tube in front and behindthe meter;- section of transit of variuos tubes positioned on thecircuit;- diameter of eventual connections.IMPORTANT - To ensure a correct operation, a savingof energy and the long-life of the appliance, the voltagepressure of the appliance must correspond to therecommended values.The adjustable connection is fixed to the comprehensiveramp by means of a threaded nut G 1/2". Interpose thesealing between the components as shown in fig. 4.Screw the parts without forcing, adjust the connection inthe required direction and tighten everything.IMPORTANT - When the final connection has beenmade, it is essential that a thorough leak test is carriedout on the hob and installation. Use some soapy water,never a flame.A) Ramp with ending nutB) SealC) Adjustable connectionFig. 4FO 0264T
