Adjustment to different types of gas
If the appliance is intended to operate with a
different gas from the gas type stated on the rating
plate and information label on the top of the hob,
change the injectors.
Remove the information label and keep it with the

pressure indicated in the Instruction.

Service or a qualified technician.
• Nozzles not supplied with the appliance must be
ordered from After Sales Service.
• Adjust the minimum setting of the taps.
NOTE: when liquid petroleum gas is used
(G30/G31), the minimum gas setting screw must
be tightened as far as it will go.
IMPORTANT: should you experience difficulty in
turning the burners knobs, please contact the
After Sales Service for the replacement of the
burner tap if found to be faulty.
Replacing the injectors (see the
injector table in the Instruction)
• Remove grids (A).

• Using a socket spanner of the appropriate size
unscrew the injector (C), unscrew the injector to
be replaced.
• Replace it with the injector suitable for the new
type of gas.

• If you have a multiple crown burner use side
spanner to replace the injector (E).
Before installing the hob, remember to affix the gas
calibration plate supplied with the injectors in such a
way that it covers the existing information relating to
gas calibration.
Adjusting minimum gas setting
of taps
To ensure that the minimum setting is correctly
adjusted, remove the knob and proceed as follows:
• tighten screw to reduce the flame height (-);
• loosen screw to increase the flame height (+).
The adjustment must be performed with the tap in
minimum gas setting position (small flame) .
• The primary air of the burners does not need to
be adjusted.
• At this stage, light up the burners and turn the
knobs from max position to minimum position
to check flame stability.
Upon completion of adjustment, reseal using sealing
wax or an equivalent material.
