Combustion
Combustion is a chemical reaction where two agents, called fuel and combustive agent, are combined and generate thermal energy (heat)
and producing new substances (smoke).
In order to understand the expression described above, we must consider this practical diagram called "combustion triangle", it consists in
three elements which are necessary for the combustion reaction to take place. These three elements are :
• fuel (Pellet)
• combustive agent (Oxygen in the air)
• source of ignition (Heat)
The reaction between fuel and the combustible agent is not spontaneous, but it takes place of a result of an external source of ignition. The
source of ignition may be represented by a heat source or a spark. The source of ignition represent the activation energy necessary to the
reagent molecules to start the reaction. With the stove off, this energy must be supplied externally (Electrical ignition resistance). Later, the
energy released by the actual reaction makes self-support possible (glowing embers and high temperature in the combustion chamber).
The fuel and combustion agent must be in suitable proportions for combustion to take place, limited by the so called "flammable range".
Here below are three EXAMPLES of combustion, the correct one is shown in figure 3:
OXYGEN

FUEL
INCORRECT combustion, the flame is pulled too much "blowtorch" style, with a great
quantity of incandescent pellet that comes out of the brazier. Correct the Pellet/air set by
decreasing the percentage of air (from 0 to -9); if this is not sufficient, also increase the
pellet drop percentage (from 0 to +9) to reach the condition shown in figure number 3.
If the changes to settings do not bring the stove back to the correct combustion conditions
shown in figure 3, immediately contact the Technical After-Sales Service.
INCORRECT combustion, "soft" flame "wood stove combustion" style with a great quantity
of unburnt pellet in the brazier. As an initial step, verify door and ashes drawer closing.
Secondly, correct the Pellet/air set by increasing the percentage of air (from 0 to +9); if
this is not sufficient, also decrease the pellet drop percentage (from 0 to -9) to reach the
condition shown in figure number 3.
If the changes to settings do not bring the stove back to the correct combustion conditions
shown in figure 3, immediately contact the Technical After-Sales Service.
CORRECT combustion, yellow/white coloured flame with a minimum quantity of pellet in
the brazier.
Ideal combustion that does not require any modifications.
Figure 3 shows a flame produced by the stove with operational power set at the maximum
value of 5.

Safety devices
The stove is equipped with sophisticated safety systems that protect from damages to the stove and/or domestic environment in case one
of the individual parts of the stove breaks or there is a malfunction with the chimney. In any case, when there is a problem, the pellet drop
is immediately interrupted and the shut-off phase is activated.
The display will show the corresponding alarm. It is possible to consult details in the chapter dedicated to alarms.
