PRINCIPLE OF OPERATION

The boiler-stove is fuelled by pellets. These are little, cylindrical
shapes of pressed wood whose combustion is controlled electro-
nically. The heat produced by combustion is mainly transmitted to
the water and partly emitted into the room by radiation.
The fuel tank (A) is located at the rear of the boiler-stove. 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) it is then
transported to the combustion crucible (D).
The ignition of the pellet is via air heated by an electrical heating
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 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 Leonardo® software to achieve high combustion efficiency
and low emissions. The synoptic panel (H) is installed on the top,
through which all phases of operation can be displayed and con-
trolled. The main phases can even be handled by remote control.
Aserial port is found at the back of the boiler-stove (optional
cable: code 621240) 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-stove
manually or automatically modulates the power to maintain or
reach this temperature. The Eco function can be enabled in small
systems (the boiler-stove shuts down and goes on again according
to the water temperature required).
NOTE regarding the fuel.
ADRIA is designed and programmed to burn wood pellets with 6 mm diameter.
Pellets are a type of fuel in the form of little cylinders, made from
compacted sawdust, compressed under high pressure with no adhesives or foreign materials. They are sold in bags of 15 kg.
For the boiler-stove to function properly, you MUST NOT burn anything else in it. Using other materials (including wood) will
render the warranty null and void. Such use is detected by laboratory analyses.
Edilkamin has designed, tested and programmed their stoves to guarantee the best performance when pellets with the following
characteristics are used:
diameter: 6 millimetres - maximum length: 40 mm - maximum moisture content: 8% - calorific value: at least 4300 kcal/kg.
If pellets with different characteristics are used, the stoves must be recalibrated – a similar procedure to that carried out by the
DEALER when the boiler-stove is ignited the first time.
Using unsuitable pellets may: decrease efficiency; cause malfunctions; stop the boiler-stove from functioning due to clogging, dirt
on theglass, unburnt fuel, etc.
A simple, visual analysis of the pellets may be carried out:
Good quality: smooth, uniform length, not very dusty.
Poor quality: with longitudinal and transverse cracks, very dusty, various lengths and mixed with foreign matter.
