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.
! In the event of single-control DRDA (DCDR) burners,
adjustment can be performed by intervening on the 2 screws
located near the tap pin (see picture).
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.

! 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.

from the recommended pressure, a suitable pressure
regulator must be fitted to the inlet pipe (in order to comply
with current national regulations).
