f Hold the heater vertically and, using a match or
cigarette lighter, light the gas as shown.
Hold the heater vertically for 1 to 2 minutes until
the catalytic reaction occurs. This is indicated
when the blue flame fades and the ceramic
element glows red. Then turn the small ring 39-E
until the air holes at 39-F are completely open.
The tool is ready for use.
Note: The fact that the sound of liquid cannot be heard
when the cartridge is shaken does not mean it is empty. No
sound will be heard even when the cartridge is full.

g The heater can be used in two modes:
C-193
i Side wings 40-G down, reflector head
completely open. In this mode the infra-red
heat waves are dominant (recommended for
the light coloured plastic splices).
ii Side wings 41-G up, reflector head opening
reduced. In this mode the heating is done only
by the hot gas (use for dark coloured plastic
splices).
h To switch off the heater, turn the red ring 41-D to
the left (in the direction of the minus sign).
