4 Handling
You can choose the size of the safety burner's flame using the tipping lever.

Position A:
Position B:
Position C:
When choosing either position A or C always turn the tipping lever to its limit. By doing this you can
identify quickly and unmistakably which position the burner was in should the flame ever go out. This will
also prevent a flash-back in the burner's nozzle.
Regulating the main flame:
• Where?
• How?
Regulating the pilot flame:
• Where?
• How?
The ignition flame should be as stable, and therefore as smooth, as possible in order to ensure a reliable
burner operation. Adjust the flame so that it cannot be extinguished unintentionally.
Adjusting the burner position:
The burner can be positioned at three different angles:
To adjust the burner to the angle which suits you the best, simply lift it out of its base and reinsert it in the
required position. The burner is thus equally well suited for left-handed and right-handed users.
The burner should not be used in the 90° position when working with wax, since dripping wax may block
the jets and cause the burner to malfunction.
