The thermal 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 hopper (A) is found on the back part of the thermal stove.
The hopper is filled through the lid that has a click-clack system,
which opens by pressing that rear part of the top.
The fuel (pellets) is transferred from the hopper (A) to the combu-
stion chamber (D) by means of a feed screw (B), which is
driven by a gear motor (C).
The pellets are ignited by the air that is heated by an electrical resi-
stance (E) and drawn into the combustion chamber by a
centrifugal fan (F). The combustion air is drawn in from the room (in
which there must be an air inlet) by the centrifugal fan
(F) through the tube (G).
The fumes produced during the combustion process are extracted
from the hearth by the same centrifugal fan (F) and
expelled through the outlet (G) located on the lower part at the back
of the stove.
The ashes fall beneath and at the side of the combustion chamber and
these must be regularly vacuumed when cold.
The thermal stove has an in-built pump that helps the hot water pro-
duced to flow to the heating system circuit.
The thermal stove has an in-built closed expansion tank and over-
pressure safety valve.
Fuel quantity, smoke extraction/combustion air supply and pump
activation are regulated by the control board in order to
obtain optimal combustion and thereby guaranteeing high efficiency.

Operating modes

(for further details, please see page 32)
The water temperature desired in the system is set on the panel (ave-
rage temperature recommended: 70 °C) and the thermal
stove adjusts the power to maintain or reach this temperature.
The Eco function can be enabled in small systems (the thermal stove
shuts down and goes on again according to the water
temperature required).
NOTE regarding the fuel.
The Mimi – Norma pellet thermal stoves are designed and programmed to burn wood pellets, 6 mm in diameter.
Pellets are a type of fuel made from compacted sawdust and chopped waste wood, compressed under high pressure with no
adhesives
or foreign materials. They are small in size, approximately 6 mm in diameter and have a cylindrical shape.
They are sold in bags of 15 kg.
For the thermal 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
Using unsuitable pellets may: decrease efficiency; cause malfunctions; stop the stove from functioning due to clogging, dirt on
the glass, unburnt fuel, etc.
