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)
FUEL
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 switch-on 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:

Safety devices

The thermo-stove is equipped with sophisticated safety systems that prevent the thermo-stove and/or living environment from being
damaged in the event of breakage of one of the parts, or failure of 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.

Regulations, Directives and Technical standards

All Aico S.p.A. products are manufactured in accordance with:
• Regulation (EU) No 305/2011
and the following directives:
• 2014/30 UE electromagnetic compatibility (EMC)
• 2014/35 UE low voltage safety (LVD)
• 2011/65 UE RoHS 2

INCORRECT combustion, the flame is pulled too much in a "blowtorch" style, with a great
quantity of incandescent pellets coming out of the brazier. Correct the pellet/air set point
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 Support Centre.
Fig. 1
INCORRECT combustion, "soft" "wood stove combustion" style flame with a great quantity
of unburnt pellets in the brazier. As an initial step, verify door and ashes drawer closing.
Secondly, correct the pellet/air set point 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 Support Centre.
Fig. 2
CORRECT combustion, yellow/white coloured flame with a minimum quantity of pellets 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.
