OPERATING PRINCIPLE
The stove is pellet-fired with electronically controlled combu-
stion. Pellets are small cylinders of pressed wood.
The heat produced by combustion is mainly used to heat
water, and only a small part radiates into the room where the
stove is installed.
The pellet hopper (A) is at the top of the stove. The hopper is
filled through the lid found at the back of the top.
The fuel (pellets) is taken from the hopper (A) and delivered
to the combustion chamber (D) by a screw feeder (B) driven
by a gearmotor (C).
The pellets are ignited by air heated with a heating element (E)
which is drawn into the combustion chamber by a centrifugal
fan (F).
The combustion air is drawn from the room (where there must
be an air intake) by the centrifugal fan (F) through pipe (G).
The combustion smoke produced is drawn out of the firebox
by the same centrifugal fan (F), and expelled from the nozzle
(H) at the bottom rear of the stove.
The ash falls into the pan (I) where it gathers for emptying.
The water in the stove is heated and sent to the heating system
by the pump built into the stove.
The stove has a built-in closed expansion tank and overpressu-
re relief valve.
The amount of fuel, the smoke extraction/combustion air sup-
ply and pump operation are controlled by an electronic circuit
board in order to achieve highly efficient fuel consumption.
Operating modes
(see page 32 for further details)
The water temperature required in the system (recommended
average of 65°C) is set on the panel, and the stove modulates
the power to maintain or reach this temperature. With small
systems, the Eco function may be enabled (the stove turns off
and on according to the water temperature).
The external covering is available in the following colours
and materials:
- grey aluminium sheet metal with amaranth ceramic top;
- grey sheet metal with beige ceramic top;
- beige or amaranth ceramic tiles.

NOTES on fuel.
The Ecoidro pellet-fired boiler-stove is designed and
programmed to burn wood pellets with 6 mm diame-
ter.
Pellets are small 6 mm diameter (approx.) fuel cylin-
ders made from sawdust and ground waste wood
pressed at high pressure without adhesives or other
foreign material.
They are sold in 15 kg bags.
In order NOT to jeopardize stove operation, do NOT
burn other substances. The use of other materials
(including wood), which can be detected by laborato-
ry analyses, invalidates the guarantee.
EdilKamin has designed, tested and programmed its
stoves to perform best with pellets with the following
characteristics:
diameter: 6 millimetres; maximum length: 40 mm;
maximum moisture content: 8 %; heat output: 4300
kcal/kg (at least)
Use of unsuitable pellets may lead to: a decrease in
efficiency; operating anomalies; stoppages due to
clogging, dirty glass, unburnt fuel, etc.
