Gas Hob Operating Instructions
Page 5 of 12
Adapting to various types of gas
Warning: Servicing should be carried out only by
authorised personnel. Should the appliance be
pre-set for a different type of gas than that
available, proceed as follows:
−
replace the injectors with the
corresponding type of gas to be used (see
table “Uses characteristics”).
−
to adjust to the minimum, use a
screwdriver on the screw placed on the tap
after turning the tap to its minimum
position.
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 (fig.10), 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.
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.
NOTE: The adjusting screw must be fully screwed
down for LPG
When converting from Natural Gas to Propane
ensure that the NG regulator is removed and
replaced with the test point assembly. A gas
regulator suitable for a supply pressure of
2.75kPa should be part of the gas tank supply and
should be adjusted with the wok burner operating
at maximum.
The appliance is factory set for Natural Gas. The
test point pressure should be adjusted to 1.00kPa
with the wok burner (or rapid burner if there is no
wok burner) operating at maximum.
Replace the old data plate with one which is
suitable for the type of gas for which the appliance
has been regulated.
Before Leaving
- Check all connections for gas
leaks with soap and water.
DO NOT
use a naked
flame for detecting leaks. Ignite all burners to
ensure correct operation of gas valves, burners
and ignition.
Turn gas taps to low flame position and observe
stability of the flame. When satisfied with the
hotplate, please instruct the user on the correct
method of operation.
In case the appliance fails to operate correctly after
all checks have been carried out, refer to the
authorised service provider in your area.
•
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, (fig.11) until the
flame is small but steady.
