2. SAFETY INSTRUCTIONS
Proper use
Basic principles
The EcoLogic boiler has been designed and tested in accordance with the safety
regulations deriving from the EN 303-5: 2012 directive. However, improper use of the boiler
can result in bodily injuries that can ultimately result in the death of users and / or third
parties as well as damages to the boiler itself or other material assets.
Handling the boiler
The boiler can only be used when it is in its proper condition. Use the boiler in the manner
described in this manual. Get informed with security measures and possible dangers.
Remove all faults and malfunctions that could affect your safety.
Using the boiler
The boiler is intended for combustion of wood pellets. Any other use is improper. The
manufacturer will not be held responsible for any damage caused by improper handling.
Proper use implies maintenance of the installed boiler, operation and maintenance
conditions prescribed by the manufacturer.
The user can enter or change only those values that are specified in this manual. Any other
parameter value will affect the control program and boiler operation, which can ultimately
lead to a break or improper operation.
Changes on the boiler
It is forbidden to make any changes on the boiler or equipment supplied. It is forbidden to
deactivate the security functions. The manufacturer will not give any warranty if the user or
a third partyperforms an unauthorized intervention on the boilerand equipment that comes
with it.
The boiler may only be used for the purpose for which it is produced.
The manufacturer does not accept any responsibility for damage
caused to persons, animals or property resulting from faults in
installation, incorrect regulation and maintenance or improper use of
the boiler.

12
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.
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.
Recommended wood pellets and standards
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 boiler.

13
Unallowed fuels
The pellets not consisting the standards mentioned in this manual is not allowed to burn
in a boiler. Using a bad quality pellet or any other material can lead to damaging your
boiler's important functions and may result in the termination of the warranty and
associated liability.
Obligatory information
All persons managing the boiler 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 boiler,
e.g. cleaning and maintaining boilers.
This instruction should always be kept near the installed boiler.
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.
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 boileris installed even though
it is not listed in this manual.
During the first installationof theboiler or in theeventof changes on centralheating system,
it is necessary to inform the competent authority in charge for control, and provide all the
necessary permits.
Safety instructions for boiler room
The boiler room must be made according to current regulations, especially regarding fire
protection. Storage of flammable materials, cleaning agents and similar materials must not
be stored in the boiler room

14
The room where the boiler is installed must be frost-resistant
The boiler must not be exposed to coldsor freezing temperatures. Extreme cold can cause
malfunction and unexpected behavior of electronic components.
Fresh air supply
For combustion of pellets and normal work boiler needs fresh air. The room in which the
boiler is installed must have an opening for fresh air supply. The recommended minimum
dimension is 30x15 cm.
Boiler safety devices
The boiler is equipped with safety systems which, in the case of
unforeseen situations, serve to stop the power supply and thus stop
the boiler operation.
Microprocessor control on the boiler: intervenes directly, turns off the boiler until
it cools down and shows an error on the display screen in case of a failure of flue
gas fan, malfunction of the dispenser engine, failure of the ignition.
Fuse: Quick fuse, protects the boiler of large current drops and short circuit inside
the boiler.
Safety Thermo Switch (STB): If boiler overheats (at 90 ° C), all pumps in the
system turn on, attempting to cool the boiler. If this fails and the temperature
continues to increase, the STB intervenes by sending the signal to the regulation,
ERROR BOILER OVERHEAT and STB ACTIVATED are displayed and the boiler
stops working. After the boiler is cooled, it is necessary to manually reset the switch
and start the boiler.
Safety switches –in case the door is not closed, the grate in the burner does not
return to its original position, an error is shown on the display and the boiler stops
working.

4. INSTALLATION
The commissioning of the system must be carried out by the personnel
authorized by ThermoFLUX d.o.o or the importer.
The warranty will not be valid if the boiler has not been commissioned
by an authorized servicer.
The first start-up includes the basic operation and maintenance of the boiler. The service
technician authorized for the first commissioning must check the functioning of the boile at
least during one complete work cycle. In some countries, it is obligatoy for first
commissioning to be controled and autorizied by chimney sweep or a person authorized
to control.
Risk of material and physical damage due to improper
commissioning. If the first start-up is done by an
unprofessional person, damage to the boiler and the
heating system may occur.
Conditions for installation
The following conditions must be completed before the system is
released.
The installation of theboiler must be done according to the regulations - with
a minimum distance of 50 cm from the side, ie 40 cm from the back of the
boiler measured from the flue gas fan. Distance in front of the boiler must be
