Pellet
Pellet is used in an automatic way by means of an automatic pellet burner. Only wood pellets
are to be used with this burner. No other fuel is allowed be used in the burner. The pellet is
deposited in the fuel tank and then automatically fed through the feeder, which is controlled by
the burner.
As fuel, it is recommended to use only premium quality wood pellet 6-8 mm diameter. Pellet of
lower quality or agropellets can only be used if approved by the manufacturer. Note that if lower
quality pellet is used, the ash produced can be signifantly bigger and the cleaning interval more
often.

Pellet fuel characteristics
The quality of the pellets, calorific power, humidity and ash content is very
important for the boiler function and efficiency!
Normally, if using pellets with low ash content (DIN+ quality certification) the burner needs
cleaning once every week. If low quality pellets are used this might be needed up to once a day.
It is prohibited the use of processed wood pellets, or other chemical treatment.
It is prohibited the use of explosive, inflammable materials, plastic, domestic
residues, etc.
NEVER BURN ANY TYPE OF CORN, CHERRY PITS, STICKS OR OTHER TYPES OF FUEL
IN THE BURNER.
