The boiler-stove is fuelled by pellets. These are little, cylin-
drical shapes of pressed wood whose combustion is controlled
electronically.
The boiler-stove is able to heat water to feed the heating system
(radiators, heated towel rails, and underfl oor heating panels), as
well as producing hot air with a fan to heat the room in which it
is installed.
The fuel tank (A) is located at the rear of the boiler-stove. Fil-
ling 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) 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
boiler-stove through the smoke extractor (F), and expelled from
the pipe union (G) located in the bottom portion of the rear of
the boiler-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 boiler-stove is transferred via a
circulator built into the boiler-stove itself, to the heating system
circuit.
The boiler-stove is designed to function with closed expansion
tank (I) 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 to achieve high combustion effi ciency and low emis-
sions.
The synoptic panel (M) is installed on the top, through which
all phases of operation can be displayed and controlled.
The main phases can even be handled by remote control.
The exchanger tubes are cleaned by means of tube-cleaners (H)
manoeuvred with a handle (L).
Aserial port is found at the back of the boiler-stove (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 32)
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).
