5 2 INSTALLING THE FITTED OVEN Fig. 5 Fig mm. 45 mm. To guarantee that the fitted appliance works properly, it is necessary that the characteristics and dimensions of the unit conform with the ones indicated in the chapter 1. To guarantee good aeration, the rear wall of the unit must be removed, and the oven should preferably be fitted so that it rests on two strips of wood, as shown in the figure; if there is a continuous worktop, it must have an opening measuring at least mm (see Fig. 6). It is of fundamental importance that the open unit housing the oven is provided with this opening, so as to guarantee proper ventilation. If not, dangerous overheating of the appliance and the walls of the unit might result. The panels of units adjacent to the oven must be made of heat-resistant material. In particular, if units are coated with a wooden veneer the glues used must be capable of supporting a temperature of 100 C. In conformity with safety regulations, once the appliance has been installed there must be no possibility of contact with electrical parts. All parts ensuring protection must be fixed in such a way that they cannot be removed without the use of some form of tool. 3 FITTED GAS - INSTALLATION REQUIREMENTS This appliance can only be installed and operate in rooms fitted with permanent ventilation according to the requirements of current UNI-CIG 7129 and 7131 regulations (VALID IN ITALY). It must be remembered that GB /

6 Fig. 7 combustion is a chemical oxidation process, during which the fuel, when combined with air, produces combustion by-products (fumes) and develops heat, generally with formation of a flame. If combustion is properly regulated, the types of gas distributed in Italy (methane, LPG or city gas) will produce carbon dioxide and steam as by-products; while if combustion takes place in the absence of oxygen, the gas, like any other fuel containing carbon, will form carbon monoxide, which has no smell or colour and is highly toxic. In particular, the following requirements must be met: The room must be provided with an external ducting system for combustion fumes, using a hood or electric fan that comes into operation automatically each time the appliance is turned on Into a chimney or branched exhaust flue (for cooking appliances only) Directly to the exterior GB /

7 The room must be provided with a system allowing an air flow sufficient to regulate combustion. The air flow rate required for combustion must not be less than 2 m 3 /h per kw installed power. The system can be created by taking air directly from outside the building through a duct with a working cross-section of at least 100 cm 2 and of a type that is not subject to accidental blockage (Fig. 8), or indirectly from adjacent rooms that are provided with an outside ventilation duct as described above and are not common parts of the building, bedrooms or other rooms in which there is a danger of fire. (Fig. 9) Fig. 8 Fig. 9 A Examples of ventilation slot for the combustion area Increasing the gap between door and floor Liquid petroleum gas, which is heavier than air, tends to collect at floor level. Rooms containing LPG tanks must therefore be fitted with openings to the outside so as to allow low-level evacuation of any leakages of gas. For this reason the LPG tanks, whether they be empty or partially filled, must never be installed or stored in rooms located below ground level (cellars, etc.). It is advisable to house only the tank being used in the room, positioning it so that it is not under the direct action of heat sources (ovens, fires, stoves, etc.) that might bring it up to temperatures of above 50 C 4 FIXING THE OVEN TO THE UNIT TYPE 1 Position the brackets A so that they are touching the oven support B (see Fig. 10) Position the chocks C so that they are touching the brackets A and so that the thickness of the unit side wall, shown on the chock, is facing towards you GB /

12 7 CONNECTING THE POWER CABLE TO THE MAINS Fit the cable with a plug suitable for the load indicated on the rating plate; if you are connecting directly to the mains it will be necessary to insert, between the appliance and the mains, an omnipolar switch with a minimum contact aperture of 3 mm, sized to suit the load and complying with current regulations (the earthing wire, green and yellow, must not be cut by the switch). The power supply cable must be positioned in such a way that it never reaches a temperature more than 50 C above the room temperature, at any point. Before connecting up, ensure that: the fuse and the domestic power supply are capable of bearing the load required for the appliance (see rating plate); the power supply is provided with an efficient earthing system, in compliance with current legal requirements; the omnipolar socket or switch can be reached with ease with the appliance installed. N.B. Do not use adapters, multiple sockets and/or extension leads. Should it be essential to do so, only use single or multiple adapters and extension leads that comply with current safety regulations, making sure that you do not exceed the current carrying capacity indicated on the adapter and on the extension leads, and the maximum power capacity indicated on the multiple adapter. GB /

13 8 GAS CONNECTION Connection of the appliance to the gas mains or to the gas bottle must be carried out as required by current UNI-CIG 7129 and 7131 regulations (valid in Italy), only after ensuring that the appliance is adjusted to use the type of gas supplied. If this is not the case, perform the operations described in the chapter 9 Adapting to different types of gas. When using bottled liquid gas, fit pressure regulators that comply with UNI-CIG 7432 regulations (valid in Italy). To ensure safe operation, adequate use of energy and a longer life for the appliance, ensure that the supply pressure complies with the values indicated in the table Burner and nozzle characteristics in the instruction manual. Should it be necessary to install a gas cooker and a fitted gas oven, under no circumstances must the two appliances be connected, or use the same cut-off tap. They must be connected separately, and each one mut have its own stop tap, making them independent of each other. Fig. 17 Fig Connecting with a rigid copper or steel pipe Connection to the gas supply must be made in such a way as to cause no strain of any kind on the appliance. An adjustable L shaped connector is provided on the appliance s supply inlet, and is sealed with a gasket. Should it be necessary to turn this connector, always replace the seal gasket (provided with the appliance). The inlet connector has a cylindrical 1 / 2 " male gas thread. GB /

14 8.2 Connecting with a continuous wall flexible stainless steel pipe with threaded connectors The inlet connector for the appliance has a cylindrical 1 / 2 " male gas thread. Only use pipes that comply with UNI-CIG 9891 regulations (in Italy) and seal gaskets that comply with UNI-CIG These pipes must be fitted so that, when extended to a maximum, they are not more than 2000 mm in length. After connecting up, ensure that the flexible metal pipe will not come into contact with moving parts, and that it is not crushed. 8.3 Checking seal On completing installation, ensure that all the connectors are perfectly sealed, using a soapy solution and never a flame. 9 ADAPTING TO DIFFERENT TYPES OF GAS Fig. 19 To adapt the oven to a type of gas that is different from the one foreseen (indicated on the labels attached to the rubber holder), proceed as follows: REPLACING THE OVEN BURNER NOZZLE Open the oven door as far as it will go Extract the sliding oven bottom GB /

15 Fig. 20 Remove the oven burner, after first taking out screw V V Fig. 21 Unscrew the oven burner nozzle using the nozzle socket wrench provided, or better still using a 7 mm socket wrench, and replace it with another suitable for the new type of gas (see table above) Replace all the components, performing the above operations in reverse order 10 ADJUSTING OVEN BURNER PRIMARY AIR SUPPLY The burner is designed so that no regulation of the primary air supply is required. GB /

16 11 ADJUSTING OVEN BURNER MINIMUM LEVEL HOW TO ADJUST THE OVEN BURNER MINIMUM LEVEL Turn the dial to Min, after first leaving it for approximately 10 minutes set to Max Remove the dial Remove the disk fixed to the frontpiece Turn the adjusting screw, located outside the thermostatic tap stem, until a small, regular flame appears (the flame can be seen through the slots at the bottom of the oven) N.B. In the case of liquid gas the adjusting screw must be completely fastened. Fig. 22 Check that the burner does not go out when the dial is turned quickly from Max to Min or when the oven door is opened and closed quickly IMPORTANT On completing this operation, replace the old rating label with a new one that corresponds to the new type of gas Should the pressure of the gas used be different from the one foreseen (or should it vary), an appropriate pressure regulator must be fitted on the inlet pipe (in Italy it must comply with UNI-CIG 7430 regulations for Channelled gas regulators ) GB /

17 CAUTIONS AND ADVICE 1. If the oven is fitted close to a cold line appliance, it is essential that it be of the tangential ventilation type. Should it not have this function, it must be provided by installing the relative kit (if possible). 2. During installation of the product, ensure that the gas supply pipe is not positioned between the rear of the oven and the wall. GB /
