FUNCTION
The maintenance function is used to interrupt the current operating
mode and activate the burning out phase. When the burn-out time
has elapsed, maintenance is enabled and the primary and secondary
air fans switch. Only the flue gas fan continues running with
controlled vacuum pressure. This serves to suction up dust and
remove radiant heat during cleaning and maintenance work.
After the cleaning and maintenance work is completed, the function
must be deactivated. The boiler switches back to the previous mode.
