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 tting on the appliance

supply ramp and this is tted with a seal in order to prevent

leaks. The seal must always be replaced after rotating the

pipe tting (seal provided with appliance). The gas supply

pipe tting is a threaded 1/2 gas cylindrical male attachment.

Connecting a exible jointless stainless steel pipe to a

threaded attachment

The gas supply pipe tting 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 exible 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

ttings for leaks using a soapy solution. Never use a ame.

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 nished, 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 ame“

burners

1. Remove the grids and slide the burners from their

housings. The burner consists of 2 separate parts (see

gure);

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 congured

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 ame position;

2. Remove the knob and adjust

the adjustment screw, which is

positioned in or next to the tap pin,

until the ame is small but steady.

3. Having adjusted the ame 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 ame does not go out.

4. Some appliances have a safety device (thermocouple)

tted. If the device fails to work when the burners are set

to the low ame setting, increase this low ame 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 nished, 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 tted to the inlet pipe (in order to comply

with current national regulations).
