Adapting to different types of gas
It is possible to adapt the appliance to a type of gas
other than the default type (this is indicated on the
rating label on the cover).
Adapting the hob
Replacing the nozzles for the hob burners:
1. Remove the hob grids and slide the burners off
their seats.
2. Unscrew the nozzles using
a 7 mm socket spanner (
see
figure), and replace them with
nozzles suited to the new type
of gas (
see Burner and nozzle
specifications table).
3. Replace all the components
by following the above instructions in reverse.
Adjusting the hob burners’ minimum setting:
1. Turn the tap to the minimum position.
2. Remove the knob and adjust the regulatory
screw, which is positioned inside or next to the tap
pin, until the flame is small but steady.
!
If the appliance is connected to a liquid gas
supply, the regulatory screw must be fastened as
tightly as possible.
3. 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 is not
extinguished.
!
The hob burners do not require primary air adjustment.
!
After adjusting the appliance so it may be used with a
different type of gas, replace the old rating label with a
new one that corresponds to the new type of gas (these
labels are available from Authorised Technical Assistance
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 hose in
accordance with current national regulations relating to
“regulators for channelled gas”.
• Is shorter than 1500 mm.
• Fits firmly into place at both ends, where it will be
fixed using clamps that comply with current
regulations.
!
If one or more of these conditions is not fulfilled or
if the cooker must be installed according to the
conditions listed for class 2 - subclass 1 appliances
(installed between two cupboards), the flexible steel
hose must be used instead (
see below).
Connecting a flexible jointless stainless steel
pipe to a threaded attachment
Make sure that the hose and gaskets comply with
current national legislation.
To prepare the hose for use, connect it to the gas
inlet pipe fitting of the appliance. (The pipe fitting is
a threaded ½ gas conical male attachment).
!
Perform the connection in such a way that the hose
length does not exceed a maximum of 2 metres,
making sure that the hose is not compressed and
does not come into contact with moving parts.
Checking the connection for leaks
When the installation process is complete, check the
hose fittings for leaks using a soapy solution. Never
use a flame.
