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
! 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).
Safety Chain
! In order to prevent accidental tipping of the appliance,
for example by a child climbing onto the oven door, the
supplied safety chain MUST be installed!
The cooker is fitted with a safety chain to be fixed by
means of a screw (not supplied with the cooker) to the
wall behind the appliance, at the same height as the chain
is attached to the appliance.
Choose the screw and the screw anchor according to
the type of material of the wall behind the appliance. If
the head of the screw has a diameter smaller than 9mm,
a washer should be used. Concrete wall requires the
screw of at least 8mm of diameter, and 60mm of length.
Ensure that the chain is fixed to the rear wall of the cooker
and to the wall, as shown in figure, so that after installation
it is tensioned and parallel to the ground level.
