The burner control stops startup during the prepurge phase (Phase 24).
The positions of the actuators for prepurging can thus be set very straightforwardly.

The prepurge position of auxiliary actuator 3 is approached in Phase 32 (FGR).
After the settings have been made, the program stop in the prepurge position should be
replaced by the program stop of the ignition position in Phase 36.
The burner control continues the startup sequence until the ignition position (Phase 36)
is reached. Then, it stops again so that the actuator’s ignition positions can be set.

To verify the ignition positions again, the program sequence can be stopped in interval
phase 44 or 52 (interval with ignited flame on completion of the relevant safety time).
On deactivation of the program stop, the burner continues its program until the operat-
ing phase (Phase 60) is reached.
If no point for the fuel / air ratio control system has as yet been predefined, the first
curvepoint «P1» to be adopted on a preliminary basis are the ignition positions of the
actuators.
