INSTRUCTIONS FOR THE INSTALLER
Electrical connection
The appliance is supplied with a standard 10
Amp service cord terminated by a 3-pin plug for
connection to a standard household socket. The
electrical supply is required to power the electronic
ignition system.
NOTE: It will be necessary for servicing purposes
to disconnect the electrical power supply. The
power point should therefore be accessible after
the appliance is installed, as specified in the local
wiring regulations.
TESTING APPLIANCE OPERATION
After installation the installer must fully test the
appliance and ensure it operates correctly before
handing it over to the customer.
GAS CONVERSIONS AND ADJUSTMENTS
Data Label
This appliance is suitable for Natural Gas and
Universal LPG; ensure that the available gas supply
matches the Data Label.
When converting from Natural Gas to Universal
LPG ensure that the NG regulator is removed
and replaced with the Test Point Assembly. An
AGA Approved gas regulator suitable for a supply
pressure of 2.75kPa should be part of the gas
tank supply and the test point pressure should be
adjusted to 2.75kPa.
Replacing the injectors
If the equipment is adjusted for a type of gas that is
different from the one available, it is necessary to
replace the burner injectors.
The choice of the injectors to replace must be
made according to the table of the "technical
characteristics" as enclosed.
Act as follows:
– remove the racks and burners.
– by means of a straight spanner L, unscrew the
injectors U (fig.7 - 7/A) and substitute it with the
corresponding one. Please note the wok burner
on models HG75FX-M and HG90FX-M has
three injectors (refer U1 & U2 of Figure 7/A for
positions)
– tighten the injectors strongly.
After changing the injectors, it is necessary to
eliminate residual natural gas in the system.
To do this you have to turn to the maximum
position then press the knob of each burner and
wait few seconds.
Adjusting the burners
The lowest flame point must always be properly
adjusted and the flame must remain on even if
there is an abrupt shift from the maximum to the
minimum position.
If this is not so, it is necessary to adjust the lowest
flame point as follows:
– start the burner up
– turn the tap up to the minimum position (small
flame)
– remove the knob from the tap rod
– introduce a flat-tip screwdriver in the hole F of the
tap (fig.8) and turn the by-pass screw up to a
proper adjustment of the lowest flame point.
For the models with triple crown is possible
adjust the lowest flame point for the external
or internal ring. Is sufficient to turn the screws
indicated in fig. 8/A.
As regards U-LPG gas burners, the by-pass
screw must be tightened completely.
MAINTENANCE
Maintenance Schedule
No regular maintenance is required for the hotplates
except cleaning.
Replacing the power supply cable

it is necessary to use a cable with a section of
3x0.75mm
2
, type H05VV-F or H05RR-F, complying
with the regulations in force.
