1. Nominal power output is obtained with fuel type C, calorific power 4,9 kWh/kg according to
standard EN 303-5:2012.
2.2.
Pellet fuel
Pellet is used in an automatic way by means of an automatic pellet feeding mechanism. Only
wood pellets are to be used with this boiler. No other fuel is allowed to be used in the boiler. The
pellet is deposited in the fuel tank at the back of the boiler, and then automatically fed through
the feeder, which is controlled by the controller.
As fuel, it is recommended to use only premium quality wood pellet 6-8 mm diameter. Note that
if lower quality pellet is used, the ash produced can be signifantly bigger and the cleaning interval
more often. The pellet bags must be stored in a dry, not too cold environment.
Table 1.
Pellet fuel characteristics
The quality of the pellets, calorific power, humidity and ash content is very
important for the boiler function and efficiency!
It is prohibited to manually feed pellets into the grate!
It is prohibited the use of processed wood pellets, or other chemical treatment.
It is prohibited the use of explosives, inflammable materials, plastic, domestic
residues, etc.
NEVER BURN ANY TYPE OF CORN, CHERRY PITS, STICKS OR OTHER TYPES OF FUEL
IN THE BURNER.
