For the parameters «home, prepurge and postpurge position», the parameter set as sup-
plied contains 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.

pressing simultaneously selection buttons «<» and «>».
The burner control stops startup in the prepurge phase (Phase 24), so that the posi-
tions of the actuators for prepurging can be straightforwardly set.

The prepurge position of auxiliary actuator 3 is approached in Phase 32 (FGR).
After the settings are made, the program stop in the prepurge position should be re-
