Gas Conversion
■ Take precautions on the operations and adjustments to be carried out when
converting from one gas to another.
■ All work must be carried out by a qualified technician.
■ Before you begin, turn off the gas and electricity supply to the appliance.
Change the injector of the burners.
(Also same method on Triple crown burner)
1
Remove the pan support, Burner lid and Flame spreader.
Unscrew the injector using a 7 mm box spanner and replace it with
the stipulated injector for new gas supply. ( see table 1. Page 27.)
Carefully reassemble the all components.
After injectors are replaced, it is advisable to strongly tighten the
injector in place.

➀
Turn the taps down to minimum.
➁
Remove the control handles from taps.
➂
Adjusting the by-pass screw.
- For converting G20 into G30, the screw must be
screwed down fully tight.
- At this stage, light up the burners and turn the
control handles from max position to minimum
position to check flame stability.
- For converting G30 into G20, please change all
valve into new one.

■ Do not dismantle the tap shaft : in the event of a malfunction, change the whole tap.
■ Before placing the burners back on the top place, make sure that the injector is
not blocked.
■ A full operational test and a test for possible leakages must be carried out after
gas conversion. (such as soap water or gas detector)
■ After completing conversion, a qualified technician or installer has to mark “V”
on the right gas category
to match with the setting
in rating plate.
Remove the previous
setting “V” mark.
