Setting of the ignition electrodes
The ignition electrodes for the burner are shown in Figure 1 together with the adjust-
ment dimensions. As the conditions may vary from boiler to boiler, the indicated di-
mensions should only be considered
as
guidelines. Ifignition problems emerge, a more
favourable adjustment
of
the electrodes, suitable for the present conditions, must be
found by experiments.

When the ignition electrodes are adjusted, the following must be observed:
• The distance
of
the ignition electrodes to the nozzle and diffuser should be checked.
• The atomising oil spray must never touch the ignition electrodes.
• The distance
of
the ignition electrodes to the diffuser and the nozzle must always
be lager than the distance
of
the spark gap. .
•
If
a nozzle with a larger spray angle is fitted, the electrodes must be adjusted back-
wards, or perhaps be adjusted slightly upwards.
