2.1 General notes
This product was designed to burn wood pellets alone.
Wood pellets are a fuel obtained from the pressing of sawdust timber, extracted from the processing and
transformation residues of dried wood material. The compactness of the product over time is guaranteed by
a natural origin substance contained in the wood: lignin. The typical small cylinder form is obtained by
extrusion.
Various types of pellets with quality and characteristics that vary depending on the processing and type of
wood species used are available on the market.
CAUTION: Always use certified quality wood pellets: ex. DIN, DIN PLUS, ÖM 7135, Pellet
Gold, Catas etc. the company does not guarantee proper hot spot functioning if low-quality pellets are
used.
The hot spots are tested and programmed
to ensure good performance and perfect quality
operation with pellets with specific characteristics:
components:
wood
length:
< 30 mm
diameter:
6-6.5 mm
lower calorific value: 4.8 kWh/kg
Humidity rate:
< 8 %
residual ash:
< 0.5 %
GOOD QUALITY pellets are smooth, shiny, slightly dusty and with regular length.
LOW QUALITY pellets are of varied lengths, dusty with vertical and horizontal splits.
Since pellet characteristics and quality greatly influence the autonomy, efficiency and proper
operation of the hot spot, we recommend:
AVOID using pellets with dimensions different from that described by the manufacturer.
AVOID using low quality pellets or pellets containing dispersed sawdust powder, resins or
chemicals, additives or adhesives.
AVOID using moist pellets.
The use of unsuitable pellets causes:
- clogging of the brazier and fume discharge ducts,
- increased consumption of fuel,
- decreased efficiency,
- no guarantee of normal hot spot operation,
- dirtying of glass,
- production of unburned granules and heavy ash.
The presence of moisture in pellets increases the volume of the capsules and crumbles,
- feeding system malfunctions
- poor combustion.
Pellets should be stored in a dry and sheltered place. Particular attention should be given to the handling of
the bags to prevent their crushing, resulting in the formation of sawdust.
THE USE OF POOR QUALITY PELLETS NOT IN ACCORDANCE WITH MANUFACTURER'S
INSTRUCTIONS NOT ONLY DAMAGE THE HOT SPOT AND COMPROMISE PERFORMANCE BUT MAY
RESULT IN FORFEITURE OF THE WARRANTY AND COMPANY LIABILITY.
