Setting the firebed level sensor

Firebed level sensor
The boiler is suitable for the combustion of wood
chips, pellets and miscanthus. Please refer to the
operating manual of the boiler for more details on fuel.
The better the fuel, the smaller the amount needed on
the tilting grate. Therefore, when the fuel is changed,
the position of the firebed level sensor must also be
changed. The sensor is behind the front cover of the
boiler.
