5. Fuel
The wood pellet is obtained by pressing wood sawdust left over from the working of natural
dried wood. The typical small, cylindrical form is obtained by passing the material through a
die. Thanks to lignin, a natural element which is released during the pressing of the raw
material, the pellets acquire a good consistency and compactness without requiring
treatment with additives or caking agents.
There are various types of pellet on the market with qualities and characteristics that vary
depending on the processes they have undergone and the type of wood used in their
production.
Since the characteristics and quality of the pellet considerably affect stove performance,
efficiency and proper operation, we recommend that you use high-quality pellets.
Manufacturer and distributor has tested and programmed its stoves and can ensure best
performance and trouble-free operation using pellets with the following specific
characteristics:

N.B. the above data refer to beech/fir wood pellets
To ensure trouble-free operation:
Do not use pellets with dimensions other than those recommended by themanufacturer.
Do not use poor quality pellets containing sawdust,bark, maize,resins or chemical
substances, additives or adhesives.
Do not use damp pellets.
Choosing other and unsuitable pellets
- obstructs the grate and flue gas pipes;
- increases fuelconsumption;
- reduces efficiency;
- means that proper stove operation cannot be guaranteed;
- causes dirtto buildup on theglass;
- leaves particles which have failed to burn and heavy cinders.
The presence of moisture in the pellets increases their volume and causes
them to split which in turn causes:
- malfunction of the fuel-loading system;
- inefficient combustion.
Pellets should be stored in a sheltered, dry place.
