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 calorific value of 4.4kWh/kg. (with 15% humidity after around 18 months of seasoning) the calorific 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 sufficiently 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 calorific 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.
Open the tank lid and load the pellets using a scoop.

.
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 filling 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-flow 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 filling. After filling, 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 first ignition and with a cold machine, re-activate
the function "air breather" - see chapter "OTHER FUNCTIONS")
BUlB tHeRMOstats - Reset:
Check by pressing the reset buttons (85 - 100°C) located on the back of the appliance, before contacting a technician (see section RESET).
