PELLETS AND FEEDING

Pellets are made by applying high pressure to sawdust, or wood waste products (not containing paint) from sawmills, carpentry
and other activities related to processing and working with wood. Given that it does not use any glue to hold it together this
type of fuel is completely environmentally friendly. In fact the compactness of the pellets over time is guaranteed by a natural
substance found in the wood itself: wood coal. In addition to being an environmentally friendly fuel in that it pushes wood
residues to the limits pellets also have technical advantages. While wood has a calori c value of 4.4kWh/kg. (with 15% humidity
after around 18 months of seasoning) the calori c value of pellets is 5 kWh/kg. Pellet density is 650kg/m3 and the water content
is equal to 8% of its weight. For this reason they do not require seasoning in order to arrive at a su ciently adequate degree of
heat yield.
The pellets used must comply with the characteristics described by the
following standards:
EN PLUS CLASS A1, ISO 17225 2 CLASS A1
and
UNI EN 303 5 with the following characteristics: water content ≤ 12%, ash
content ≤ 0.5% and lower calori c value >17 MJ/kg (in the case of boilers).
The manufacturer always recommended using pellets with a diameter of
6 mm with its products.
PELLET STORAGE
In order to ensure problem-free combustion pellets must be stored in a
dry place.
THE USE OF EXPIRED PELLETS OR ANY OTHER MATERIAL WILL AFFECT THE FUNCTIONALITY OF YOUR
GENERATOR AND MAY LEAD TO THE TERMINATION OF THE WARRANTY AND CESSATION OF ANY ACCOMPANYING
RESPONSIBILITY ON THE PART OF THE MANUFACTURER

CHECKS AND PRECAUTIONS FOR FIRST IGNITION

IMPORTANT!
IN ORDER FOR THE GENERATOR TO WORK PROPERLY, THE HYDRAULIC SYSTEM'S PRESSURE MUST BE BETWEEN
0.6 AND 2.5 BAR.
If the pressure detected by the digital pressure switch is below 0.6 or above 2.5 bar, it triggers a boiler alarm.
Bringing the water pressure within the standard values, it is possible to reset the alarm by pressing the button
(The alarm can be reset only if the fumes motor has stopped and 15 minutes have elapsed from the display of the alarm)

THE PELLET LOADING MOTOR DOES NOT WORK:

Due to the lling of the system, it is normal that there is air inside the circuit.
During the 1st ignition cycle, water movement causes the displacement of air bubbles and their out- ow from the automatic
vents out of the system. This can cause the pressure to drop and activate the minimum pressure switch, which stops the motor
that transports the pellets and, therefore, the heat generator.
Vent out the system, if necessary even multiple times, to remove the air, and reload it if the pressure is too low.
It is not a malfunction, but a normal occurrence due to its lling. After lling, the plumber must always thoroughly vent the
system, using the special vents in the circuit and running the "air breather" function on the machine. (After the rst ignition and
with a cold machine, re-activate the function "air breather" - see chapter "OTHER FUNCTIONS")
