and a seal "G" is fitted at the end

"L" of the pipe to be connected to

the gas mains. This fitting should

not be removed. When the

connection pipe (flexible or rigid)

is dismounted, the fitting "R"

should be locked in place using a

spanner before unscrewing the

metal pipe bolt. This is to prevent the fitting "R" from slipping

and so as not to cause any leaks from sleeve "L". If the

appliance is designed for left and right gas connection, the

cap should be inverted and the seal supplied with the

appliance should be replaced when changing the

connection.

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 s

teel 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.

 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).
