The boiler is fuelled by pellets. These are little, cylindrical
shapes of pressed wood whose combustion is controlled elec-
tronically.
The fuel tank (A) is located at the rear of the boiler. Filling the
tank is through the back of the lid at the rear of the top.
The fuel (pellets) is taken from the storage tank (A) and, via an
Archimedes' screw (B) activated by a gear motor (C), is tran-
sported into a second Archimedes' screw activated by a second
gear motor it is then transported to the combustion crucible (D).
The ignition of the pellet is via air heated by an electrical he-
ating element (E) and is sucked into the crucible by a 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
thermo-stoves through the smoke extractor (F), and expelled
from the pipe union (G) located in the bottom portion of the
rear of the boiler.
The ash falls under and beside the crucible in which is housed
an ash (H) tray from which the ash must be periodically remo-
ved by vacuuming when cool.
The entire boiler and door are insulated which makes it more
effi cient so that the water hot water produced by the boiler is
not dissipated in the place of installation but is conveyed only
to the hydraulic system.
The door has a safety peep-hole for checking the fl ame.
The boiler is designed to function with closed expansion tank
(I) and pressure valve, both of which are built in.
A hydraulic kit (P) is located on the boiler which consists of:
circulator,thermostatic mixing valve, safety valve, expansion
tank
The inclusion of the anti-condensation thermostatic valve
prevents corrosion that would otherwise compromise the life of
the boiler body.
Fuel quantity, smoke extraction/combustion air supply and
pump activation are regulated by the control board which is
equipped with Leonardo ® software to achieve high combustion
effi ciency and low emissions. In addition it is equipped with a
bipolar socket for connection to an external graphics panel and/
or to Domoklima.
The synoptic panel (L) which allows managing and viewing all
the operating phases, is installed on the door.
A serial port is found at the back of the boliler (optional cable:
code 640560) to be connected to devices that allow remote
ignition (e.g. remote telephone, local thermostat).
Operating modes
(for further details, please see page 35)
The temperature of the water required in the system is set via
the panel (standard recommendation 70° C) and the boiler
manually or automatically modulates the power to maintain or
reach this temperature.
The Eco function can be enabled in small systems (the boiler
shuts down and goes on again according to the water tempera-
ture required).

Innovative ceramic combustor with catalyst unitwhich in-
creases the combustion temperature, ensuring high effi ciency
while signifi cantly reducing emissions. The high combustion
temperature reduces ash production to a minimum, limiting
required cleaning to once every two weeks (depending on the
type of pellets used and the hydraulic system).
