The pellet stove is equipped with system which ensures optimal burning.
The system ensures excellent operation thanks to two sensors measuring the pressure level in the
combustion chamber and smoke temperature. The detection of and subsequent optimisation of these two
parameters is continuous in order to correct opera- tion anomalies in real time
.
The system offers constant combustion, automatically regulating the draft based on the characteristics of the
chim- ney flue (bends, length, shape, diameter, etc..) and environmental conditions (wind, humidity,
atmospheric pressure, installations at high altitude, etc.). The standards for installation must be respected.
The system is also able to recognise the type of pellets and automatically adjust the flow moment by moment to
ensure the required level of combustion (use wood pellets with a diameter of approximately 6 mm).

Picture 2.1
The stove is fuelled by pellets. These are little, cylindrical shapes of pressed wood whose combustion is
controlled electronically. The heat produced by combustion is mainly transmitted to the water and partly
emitted into the room by radiation
.
The fuel tank - hopper (А) is located at the back of the stove. Loading the tank is thru the back of the lid at the
rear of the top. The fuel (pellets) is taken from the tank (A) and via an Archimedes screw (В) powered by
electric gear motor (С) is transported to the combustion chamber (D).
The ignition of the pellets as made by air, heated by electrical heating element (Е) which is sucked into the
combustion chamber by the smoke extractor (F).
The combustion air is drawn into the room (where there must be an air intake) smoke extractor
(F).
The smoke produced by combustion, is extracted from the stove through the smoke extractor
(F)
and expelled
from the pipe union
located in the bottom part of the rear of the stove
.
The ash falls under and beside the crucible in which is housed an ash tray from which the ash must be
periodically removed by vacuuming when cool.
The hot water produced by the stove is transferred by circulation pump build in the stove to the system.
Filling and empting of the system is made by build in valve and control manometer Picture.2.1.
The stove is
designed to function with closed expansion tank
(Н)
and pressure valve, both of which are built in
.
Fuel quantity, smoke extraction/combustion air supply and pump activation are regulated by the control
board
,
which is equipped with software to achieve high combustion efficiency and low emissions
. The control
panel (G) is placed on the top of the stove and can control, check and see all phases from the work of the
stove.
