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.

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), 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-
placed by the program stop of the ignition position in Phase 36.
