Hold the appliance with the burner pointing down and away
from the body.
Without applying pressure, position the nozzle of the refill
cartridge on the gas valve.
Press the refill cartridge a few millimeters into the gas valve
of the flambé burner. A light sound of hissing will be heard
as the flambé burner reservoir is being filled. The gas tank
of the flambé burner will be filled now.
Spurts of liquid gas emitted during refilling indicate that the
adaptor ring is inappropriate or that the reservoir is already full.
After a maximum of 10 seconds, interrupt the refilling and
pause for a few seconds.
Repeat the process as described earlier for a further 10
seconds. The reservoir of the flambé burner is now full.
After filling the tank, the flambé burner should be kept in a
vertical position for 2 minutes to allow for the filled up gas
to warm up and the escaped gas to dissipate. Do not touch
the ignition button during this period as time must lapse to
render the instrument fit and safe for use.
