Combustion Manager
The combustion manager W-FM is the control unit of the burner.
It controls the sequence of operation and monitors the flame.
Operating panel
The values and parameters of the combustion manager can be displayed and
changed at the operating panel.
Burner motor
The burner motor drives the fan wheel.
Ignition unit
The electronic ignition unit creates a spark at the electrode, which ignites the fuel/
air mixture.
Ionisation electrode
The combustion manager monitors the flame signal via the ionisation electrode.
If the flame signal becomes too weak, the combustion manager carries out a con-
trolled shutdown.
