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 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.

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.

•  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

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 (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.

 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).

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.

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  nozzles  on  separate  “double  flame  “ 

burners

1. Remove the grids and slide the burners from their 

housings. The burner consists of 2 separate parts (see 

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.

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).
