the cooker is in the installed position, place a
duplicate data plate on a surface of the cabinetry
adjacent to the cooker.
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 finished, 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 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 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 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).
Post Installation Checks

and safe operation before leaving. Test all burners
individually and in combination.
Leak Check
• Ensure all gas control knobs are in the Off

• Ensure the gas supply is switched on.
• Spray a solution of soapy water onto all gas joints
as well as the full length of any flexible hoses.
UNDER NO CIRCUMSTANCES USE A NAKED
FLAME IN CHECKING FOR LEAKS.
If bubbles appear anywhere, turn the gas supply off,
check all connections and retest. If satisfactory
operation cannot be achieved, contact place of
purchase or their appointed agent for service.
Flame check
