Installation

!

 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 (see 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 current national regulations. 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.

In a chimney stack or branched flue. 

(exclusively for cooking appliances)

Directly to 

the Outside

•  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

3

/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

2

; 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.

•  Intensive and prolonged use of the appliance may necessitate 

supplemental ventilation, e.g. opening a window or increasing the power 

of the air intake system (if present).

•  Liquid petroleum gas sinks to the floor as it is heavier than air. Therefore, 

rooms containing LPG cylinders must 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

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 200 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 (see figure).

•  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.

•  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.

Before the installation remove the grids and burners from the hob and turn it 

upside down, making sure you don’t damage the thermocouples and spark 

plugs.

Apply the seals that come with the 

appliance along the outer edges of 

the hob to prevent any passage of air, 

humidity and water (see Figure).

For proper application make sure the 

surfaces to be sealed are clean, dry and 

free of any grease/oil.

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).

560 mm

.

45 mm.

Where a hob is installed above an oven without a forced ventilation cooling 

system, adequate ventilation must be provided inside the cabinet by means 

of air holes through which air can pass (see figure).

Electrical connection

Hobs equipped with a three-pole power supply cable are designed to operate 

with alternating current at the voltage and frequency indicated on the data 

plate (this is located on the lower part of the appliance). The earth wire in the 

cable has a green and yellow cover. If the appliance is to be installed above 

a built-in electric oven, the electrical connection of the hob and the oven must 

be carried out separately, both for electrical safety purposes and to make 

extracting the oven easier. 

Connecting the supply cable to the mains

Install a standardised plug corresponding to the load indicated on the data 

plate. 

The appliance must be directly connected to the mains using an omnipolar 

circuit-breaker with a minimum contact opening of 3 mm installed between the 

appliance and the mains.  The circuit-breaker must be suitable for the charge 

indicated and must comply with current electrical regulations (the earthing 

wire must not be interrupted by the circuit-breaker). The supply cable must 

not come into contact with surfaces with temperatures higher than 50°C.

!

 The installer must ensure that the correct electrical connection has been 

made and that it is compliant with safety regulations.

Before connecting to the power supply, make sure that:

•  the appliance is earthed and the plug is compliant with the law.

•  the socket can withstand the maximum power of the appliance, which is 

indicated on the data plate.

•  the voltage is in the range between the values indicated on the data plate.

•  the socket is compatible with the plug of the appliance. If the socket is 

incompatible with the plug, ask an authorised technician to replace it. Do 

not use extension cords or multiple sockets.

!

 Once the appliance has been installed, the power supply cable and the 

electrical socket must be easily accessible.

!

 The cable must not be bent or compressed.

!

 The cable must be checked regularly and replaced by authorised technicians 

only (see Assistance).

!

 The manufacturer declines any liability should these safety measures not 

be observed.

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.

Attention!

 Before connection remove  a transport plug from the connecting 

hole of the cooker gas pipeline

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.

There is an adjustable L-shaped pipe fitting on the 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.

Replacing the Triple ring burner nozzles

1.  Remove the pan supports and lift the burners out of their housing. The 

burner consists of two separate parts (see pictures).

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

with models that are configured for use with the new type of gas (see Table 

1). The two nozzles have the same hole diameter.

3.  Replace all the components by completing the above operations 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.

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).
