2 INSTALLING THE FITTED OVEN

To guarantee that the fitted appliance works properly, it is necessary that thecharacteristics and dimensions of the unit conform with the ones indicated inthe chapter 1.

To guarantee good aeration, the rear wall of the unit must be removed, andthe oven should preferably be fitted so that it rests on two strips of wood, asshown in the figure; if there is a continuous worktop, it must have an openingmeasuring at least 45 × 560 mm (see Fig. 6).

It is of fundamental importance that the open unit housing the oven isprovided 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-resistantmaterial. In particular, if units are coated with a wooden veneer the gluesused must be capable of supporting a temperature of 100 °C. In conformitywith safety regulations, once the appliance has been installed there must beno possibility of contact with electrical parts. All parts ensuring protectionmust be fixed in such a way that they cannot be removed without the use ofsome form of tool.

3 FITTED GAS OVENS - INSTALLATION REQUIREMENTS

This appliance can only be installed and operate in rooms fitted withpermanent ventilation according to the requirements of current UNI-CIG7129 and 7131 regulations (VALID IN ITALY). It must be remembered that

combustion is a chemical oxidation process, during which the fuel, whencombined with air, produces combustion by-products (fumes) and developsheat, generally with formation of a flame. If combustion is properlyregulated, the types of gas distributed in Italy (methane, LPG or city gas) willproduce carbon dioxide and steam as by-products; while if combustiontakes place in the absence of oxygen, the gas, like any other fuel containingcarbon, will form carbon monoxide, which has no smell or colour and ishighly toxic. In particular, the following requirements must be met:

• The room must be provided with an external ducting system forcombustion fumes, using a hood or electric fan that comes into operationautomatically each time the appliance is turned on

• The room must be provided with a system allowing an air flow sufficient toregulate combustion. The air flow rate required for combustion must not beless than 2 m3/h per kW installed power. The system can be created bytaking air directly from outside the building through a duct with a workingcross-section of at least 100 cm2 and of a type that is not subject toaccidental blockage (Fig. 8), or indirectly from adjacent rooms that areprovided with an outside ventilation duct as described above and are notcommon parts of the building, bedrooms or other rooms in which there isa danger of fire. (Fig. 9)

• Liquid petroleum gas, which is heavier than air, tends to collect at floorlevel. Rooms containing LPG tanks must therefore be fitted withopenings to the outside so as to allow low-level evacuation of anyleakages of gas. For this reason the LPG tanks, whether they be empty orpartially filled, must never be installed or stored in rooms located belowground level (cellars, etc.). It is advisable to house only the tank beingused in the room, positioning it so that it is not under the direct action ofheat sources (ovens, fires, stoves, etc.) that might bring it up totemperatures 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 thethickness of the unit side wall, shown on the chock, is facing towards you

7 CONNECTING THE POWER CABLE TO THE MAINS

Fit the cable with a plug suitable for the load indicated on the rating plate; ifyou are connecting directly to the mains it will be necessary to insert,between the appliance and the mains, an omnipolar switch with a minimumcontact aperture of 3 mm, sized to suit the load and complying with currentregulations (the earthing wire, green and yellow, must not be cut by theswitch).

The power supply cable must be positioned in such a way that it neverreaches a temperature more than 50 °C above the room temperature, at anypoint.

Before connecting up, ensure that:

• the fuse and the domestic power supply are capable of bearing the loadrequired for the appliance (see rating plate);

• the power supply is provided with an efficient earthing system, incompliance with current legal requirements;

• the omnipolar socket or switch can be reached with ease with theappliance installed.

N.B. Do not use adapters, multiple sockets and/or extension leads. Should it be essen-tial to do so, only use single or multiple adapters and extension leads that complywith current safety regulations, making sure that you do not exceed the currentcarrying capacity indicated on the adapter and on the extension leads, and themaximum power capacity indicated on the multiple adapter.


8 GAS CONNECTION

Connection of the appliance to the gas mains or to the gas bottle must becarried out as required by current UNI-CIG 7129 and 7131 regulations (valid inItaly), only after ensuring that the appliance is adjusted to use the type of gassupplied. If this is not the case, perform the operations described in thechapter 9 “Adapting to different types of gas”.

When using bottled liquid gas, fit pressure regulators that comply withUNI-CIG 7432 regulations (valid in Italy).

To ensure safe operation, adequate use of energy and a longer life for theappliance, ensure that the supply pressure complies with the values indicatedin 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 nocircumstances must the two appliances be connected, or use the same cut-offtap. They must be connected separately, and each one mut have its own stoptap, making them independent of each other.

8.1 Connecting with a rigid copper or steel pipe

Connection to the gas supply must be made in such a way as to cause nostrain of any kind on the appliance. An adjustable “L” shaped connector isprovided on the appliance’s supply inlet, and is sealed with a gasket. Should itbe necessary to turn this connector, always replace the seal gasket (providedwith the appliance). The inlet connector has a cylindrical 1/2" male gas thread.

Fig. 17 Fig. 18




8.2 Connecting with a continuous wall flexible stainless steel pipe withthreaded 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 sealgaskets that comply with UNI-CIG 9264. 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 intocontact 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

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

Fig. 19




• Remove the oven burner, after first taking out screw “V”

• Unscrew the oven burner nozzle using the nozzle socket wrench provided,or better still using a 7 mm socket wrench, and replace it with anothersuitable for the new type of gas (see table above)

• Replace all the components, performing the above operations in reverseorder

10 ADJUSTING OVEN BURNER PRIMARY AIR SUPPLY

The burner is designed so that no regulation of the primary air supply isrequired.

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 asmall, regular flame appears (the flame can be seen through the slots at thebottom of the oven)

• Check that the burner does not go out when the dial is turned quicklyfrom 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 (orshould it vary), an appropriate pressure regulator must be fitted on theinlet pipe (in Italy it must comply with UNI-CIG 7430 regulations for“Channelled gas regulators”)

N.B. In the case of liquid gas the adjusting screw must be completely fastened.

Fig. 22




CAUTIONS AND ADVICE

1. If the oven is fitted close to a cold line appliance, it is essential that it be ofthe tangential ventilation type. Should it not have this function, it must beprovided by installing the relative kit (if possible).

2. During installation of the product, ensure that the gas supply pipe is notpositioned between the rear of the oven and the wall.
