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 begin using the hose, remove the hose holder on the
appliance (the gas supply inlet on the appliance is a
cylindrical threaded 1/2 gas 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 tightness of the connection
When the installation process is complete, check the
hose fittings for leaks using a soapy solution. Never use
a flame.
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 fi gure),
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".
We recommend cleaning the oven before using it for the
first time, following the instructions provided in the "Care
and maintenance" section.
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.
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
