For the parameters HomePos, Prepurge position and Postpurge position, the parameter
set supplied offers presettings. These should be checked and, if necessary, adapted,
either now or during the following program stops.
There is no presetting for the ignition position. In this section, a valid setting must be
made because otherwise, the burner cannot be started up.

To start the burner, select Autom/Manual/Off, and then Manual.

If startup shall be watched, the display can be changed to Normal operation by
pressing simultaneously selection buttons «<» and «>».
The burner control stops startup in the prepurge phase (phase 24), enabling the
positions of the actuators for prepurging to be straightforwardly set.

Note!
The prepurge position of auxiliary actuator 3 is approached in phase 32 (flue gas
recirculation (FGR)).
After the settings are made, the program stop in the prepurge position should be
replaced by the program stop of the ignition position in phase 36.
