If a post combustion purge is selected (with option parameter 7.9), a normal shutdown post purge will be performed at low fire. The drives will move to the low fire position (if not already there) and the post-purge time will then start. If the burner has turned off because the fuel profile selection has been removed (i.e. set to NONE), no post-purge will be performed. Děkuji.
