1.5 Basic principles and operation
The Interio pellet stove is a special heater intended exclusively for domestic use and
intended only for burning wood pellets of 6 mm diameter and 30 mm length. During
operation, the integrated heat exchanger produces hot water which is delivered to a
central heating system. The integrated pump only switches on when the preset water
temperature in the system (50°C) is reached. For normal operation, it is only necessary
to start the stove and select the desired power value or temperature. By installing the
room thermostat, it is possible to automatically ignite and control the stove. The pellets
automatically fall into the burn pot and then are ignited with an electric heating
cartridge. Depending on the set value of the power, the pellet conveyor automatically
adds the required amount of pellets. The required air supply for combustion into the
combustion chamber is controlled. The resulting heat energy in the combustion
chamber is supplied to the central heating. At the end of the combustion chamber
there is an exhaust fan, which releases the flue gases created in the chimney. Every
day it is recommended to clean the ashes. Every 1-2 months or after consumption of
approx. 500kg Enplus (A1) pellets a cleaning of the flue gas chamber and the pipe
heat exchanger is required. The devices are designed and tested so that they can be
installed in homes and have the necessary approvals. For the combustion air is needed.
For this reason, the combined use of kitchen exhaust systems, and the ventilation in
the same room with a stove is not allowed.

regulation and maintenance, and improper use of the boiler.

16
3.2 Pellets that can be used in boilers
The boiler is designed exclusively for burning wood pellets with a
diameter of 6 mm and a length of 10-30 mm.
3. 2.1 What is pellet
Pellet is obtained from wood, if it is
possible, from the core of the trunk with
the lowest proportion of bark. The bark
contains the most moisture, dust and
impurities that wood gets during growth,
therefore has a lower caloric value than
the core, and another problem is that it
leaves the sediment when burning. Ideal
wood for pellet production is one that does
not burn too long or too short and creates
a long-lasting glow. Pellets are made from
sawdust waste (typically in a ratio of 20-40% softwood + 60-80% hardwood), in
special machine under high pressure which leads to thickening. It is not allowed to
use any additives or glue during the pellet.production The pellet contains a minimal
amount of moisture and ash, and has a maximum energy value for the type of
wood from which they are produced.
3.2.2 Recommended wood pellets and standars
Pellets quality arises from Standard pellets C1 to EN 303-5: 2012 Table 7; Water
content less than 12% according to DIN 51731 - HP 5, DINplus certification program
and ÖNORM M 7135 - HP 1 or EN PLUS - UNI EN 14961 - 2 (UNI EN ISO 17225-2)
class A1 or A2, 6 mm diameter, length 10-30 mm.
Particular attention should be paid to the quality of wood pellets. Low-
grade pellets can cause malfunction of the stove.
3.2.3 Unallowed fuels
The pellets not consisting the standards mentioned in this manual is not allowed
to burn in a stove. Using a bad quality pellet or any other material can lead to
damaging your stoves's important functions and may result in the termination of
the warranty and associated liability.

17
3.3 Obligatory information
All persons managing the stove must read the manual before starting to
use it and in particular the "Safety instructions".
This applies especially to persons who occasionally work on a stove, e.g.
cleaning and maintaining stoves.
This instruction should always be kept near the installed stove.
Children aged 8 and over, persons with reduced physical, motor or mental capacity,
persons with insufficient experience and training, may use a device of this kind if they
have been provided with supervision or have been given instructions regarding the
safe use of the device and have been presented the dangers arising from it. Children
should not play with such devices. The devices must not be cleaned or maintained by
children without proper supervision.
3.4 Local standards
All local laws must be respected during installation, as well as standards
and norms that are in force in the country where the stove is installed
even though it is not listed in this manual.
