! Before operating your new appliance please read this instruction booklet carefully. It contains important information for safe use, installation and care of the appliance.

! Please keep these operating instructions for future reference. Pass them on to possible new owners of the appliance.

Positioning

! Keep packaging material out of the reach of children. It can become a choking or suffocation hazard (

Precautions and tips

! The appliance must be installed by a qualified professional according to the instructions provided. Incorrect installation may cause harm to people and animals or may damage property.

! This unit may be installed and used only in permanently ventilated rooms in accordance with British Standard Codes Of Practice: B.S. 6172 / B.S. 5440, Par. 2 and B.S. 6891 Current Editions. The following requirements must be observed:

• The room must be equipped with an air extraction system that expels any combustion fumes. This may consist of a hood or an electric fan that automatically starts each time the appliance is switched on.

see

also be equipped with vents to allow gas to escape in the event of a leak. As a result LPG cylinders, whether partially or completely full, must not be installed or stored in rooms or storage areas that are below ground level (cellars, etc.). It is advisable to keep only the cylinder being used in the room, positioned so that it is not subject to heat produced by external sources (ovens, fireplaces, stoves, etc. ) which could raise the temperature of the cylinder above 50°C.

Fitting the appliance

Gas and mixed hobs are manufactured with type X degree protection against overheating. The following precautions must be taken when installing the hob:

• Kitchen cabinets adjacent to the appliance and taller than the top of the hob must be at least 600 mm from the edge of the hob.

• Hoods must be installed according to their relative installation instruction manuals and at a minimum distance of 650 mm from the hob.

• Place the wall cabinets adjacent to the hood at a minimum height of 420 mm from the hob (

see figure

If the hob is installed beneath a wall cabinet, the latter must be situated at a minimum of 700 mm above the hob (

see figure

• The room must also allow proper air circulation, as air is needed for combustion to occur normally. The flow of air must not be less than 2 m

• Liquid petroleum gas sinks to the floor as it is heavier than air. Therefore, rooms containing LPG cylinders must

/h per kW of installed power. The air circulation system may take air directly from the outside by means of a pipe with an inner cross section of at least 100 cm the opening must not be vulnerable to any type of blockages.

The system can also provide the air needed for combustion indirectly, i.e. from adjacent rooms fitted with air circulation tubes as described above. However, these rooms must not be communal rooms, bedrooms or rooms that may present a fire hazard.

• The installation cavity should have the dimensions indicated in the figure.

Fastening hooks are provided, allowing you to fasten the

hob to tops that are between 20 and 40 mm thick. To ensure the hob is securely fastened to the top, we recommend you use all the hooks provided.

! Use the hooks contained in the “accessory pack”

• Where the hob is not installed over a built-in oven, a wooden panel must be installed as insulation. This must be placed at a minimum distance of 20 mm from the lower part of the hob.

Ventilation

To ensure adequate ventilation, the back panel of the cabinet must be removed. It is advisable to install the oven so that it rests on two strips of wood, or on a completely flat surface with an opening of at least 45 x 560 mm (

see diagrams

! The hob can only be installed above built-in ovens with a cooling ventilation system.

Gas connection

The appliance should be connected to the main gas supply or to a gas cylinder in compliance with current national regulations. Before carrying out the connection, make sure the cooker is compatible with the gas supply you wish to use. If this is not the case, follow the instructions indicated in the paragraph “Adapting to different types of gas.” When using liquid gas from a cylinder, install a pressure regulator which complies with current national regulations.

! Check that the pressure of the gas supply is consistent with the values indicated in Table 1 (“Burner and nozzle specifications”). This will ensure the safe operation and longevity of your appliance while maintaining efficient energy consumption.

There is an adjustable

L-shaped pipe fitting on the

LL appliance supply ramp and this is fitted with a seal in order to prevent leaks. The seal must always be replaced after rotating the pipe fitting (seal provided with appliance). The gas supply pipe fitting is a threaded 1/2 gas cylindrical male attachment.

Connecting a flexible jointless stainless steel pipe to a threaded attachment

The gas supply pipe fitting is a threaded 1/2 gas cylindrical male attachment. These pipes must be installed so that they are never longer than 2000 mm when fully extended. Once connection has been carried out, make sure that the flexible metal pipe does not touch any moving parts and is not compressed.

! Only use pipes and seals that comply with current national regulations.

Checking the tightness of the connection

! When the installation process is complete, check the pipe fittings for leaks using a soapy solution. Never use a flame.

Adapting to different types of gas

To adapt the hob to a different type of gas other than default type (indicated on the rating plate at the base of the hob or on the packaging), the burner nozzles should be replaced as follows:

1. Remove the hob grids and slide the burners off their

seats.

2. Unscrew the nozzles using a 7 mm socket spanner,

and replace them with nozzles for the new type of gas (see table 1 “Burner and nozzle characteristics”).

3. Reassemble the parts following the above procedure in

the reverse order.

4. Once this procedure is finished, replace the old rating

sticker with one indicating the new type of gas used. Sticker are available from any of our Service Centres.

Connection with a rigid pipe (copper or steel)

! Connection to the gas system must be carried out in such a way as not to place any strain of any kind on the appliance.

Replacing the nozzles on separate “double flame “ burners:

1. remove the grids and slide the burners from their housings. The burner consists of 2 separate parts (

);

figure

2. unscrew the burers with a 7 mm wrench spanner. The internal burner has a nozzle, the external burner has two (of the same size). Replace the nozzle with models suited to the new type of gas (see table 1).

3. replace all the components by repeating the steps in reverse order.

• Adjusting the burners’ primary air :

Does not require adjusting.

• Setting the burners to minimum:

1. Turn the tap to the low flame position.

2. Remove the knob and adjust the adjustment screw, which is positioned in or next to the tap pin, until the flame is small but steady.

see

3. Having adjusted the flame to the required low setting, while the burner is alight, quickly change the position of the knob from minimum to maximum and vice versa several times, checking that the flame does not go out.

4. Some appliances have a safety device (thermocouple) fitted. If the device fails to work when the burners are set to the low flame setting, increase this low flame setting using the adjusting screw.

5. Once the adjustment has been made, replace the seals on the by-passes using sealing wax or a similar substance.

! If the appliance is connected to liquid gas, the regulation screw must be fastened as tightly as possible.

! Once this procedure is finished, replace the old rating sticker with one indicating the new type of gas used. Stickers are available from any of our Service Centres.

! Should the gas pressure used be different (or vary slightly) from the recommended pressure, a suitable pressure regulator must be fitted to the inlet pipe (in order to comply with current national regulations).
