Operating principle
The operating voltage will be transformed to 1.6 kV, so that a capacitor can be charged. Once the
above voltage is reached, a spark gap in the casing becomes conductive, while the capacitor is
being discharged via the high-energy spark plug. Thus, a light arc with high energy content is
generated. The electronic system is dimensioned in such a way that a discharge frequency of
approx. 25 Hz will be generated. The energy content of the spark as well as the high ignition fre-
quency will facilitate the problem-free ignition of the fuel-air mixture in the burner. The igniter is
designed short-circuit-proof and secured against surge voltages. Should the appliance be started
with an open discharge circuit or with a faulty high-energy spark plug, the operating voltage will be
automatically cut off and the appliance be blocked. A re-start is only possible by switching off the
operating voltage (with the push-button being released). An ON time of 66 % is possible, despite
the high currents that flow during the ignition process.

Start-up
You have to charge the battery before the first startup!
Before starting the igniter, check the physical condition of the ignition lance and, especially, of the
ignition cable. Should a cable plug or its insulation be damaged, the appliance must not be used.
If the red LED is on, the discharge voltage is reached and the startup to be omitted and the batteries
to be recharge immediately. The igniter must only be started with the ignition lance inside the
burner.
Operating outside of the burner is not allowed!
The appliance shall be started in the very place, where it is supposed to be used. In order to start
the appliance, connect the high-voltages cable of the ignition lance with the igniter’s high-voltage
(HV) socket. A Equipotential bonding must be established between the grounding bolt on the igniter
and the burner. The equipotential bonding line should be at least a 4 mm² cable.
Position the spark plug at the burner close to the fuel emitted from the burner nozzle.
Then turn on switch S1 underneath the appliance inlet for the battery charger. The igniter is actually
started by pressing the push-button next to the carrier handle. An internal circuit will signal via the
indicator light installed in the appliance that the igniter is ready for operation. An intensive light arc
will become visible at the high-energy spark plug. The fuel inlet can now be opened. The energy
content and the high ignition frequency will facilitate a problem-free ignition of the fuel-air mixture.
After the flame has appeared, the igniter can be deactivated, while the lance should be speedily
removed from the flame area (with the spark plug’s admissible temperature being observed!) and
the spark plug should not be touched. The plug’s retention time in the flame will generate temper-
atures than can cause burns.
