There is a strong spark created between the two ignition
electrodes to ensure that the injected fuel will ignite.
The necessary ignition voltage is generated by the ignition
transformer.
The exact adherence to the adjustment dimensions is a
basic requirement for the proper function of the burner, for
good exhaust values and the long idle time of the ignition
electrodes.
There is always a ignition spark between the two ignition
electrodes, during cold and hot water operation (continu-
ous ignition).
This is a safety measure, so that injected fuel will be ignited
in any case and cannot accumulate unburned in the on-de-
mand heater (deflagration hazard).
