5. Fuel material
The fuel material specified is lump wood. No wood quality is specified. It is recommended to burn lump wood cut in maximum
lengths as per the table of technical parameters. The wood must be combusted as dry as possible, with at least 15% humidity
max. Damp wood releases water when combusted, which then condensates on the walls of the boiler body and the chimney. This
results in the emergence of aggressive substances which markedly reduce the boiler and chimney life. Burning damp wood also
results in a marked boiler power reduction.
