and possible hazards. Remove any faults that could affect the safety. The operation of
a faulty boiler can cause fier or explosion.
The boiler is intended for combustion of wood pellets and wood. Any other use is
incorrect. It is forbidden to burn any other fuel other than pellets and wood. The
manufacturer will not assume responsibility for any damage caused by improper
handling. Correct use implies maintenance of the installed boiler, operation and
maintenance conditions prescribed by the manufacturer.
The user can enter or change only the values specified in this manual. Any
other value of the parameters will affect the control program, and the
operation od the boiler, wich can ultimately lead to the termination of the
correct operation. In that case, the boiler is not subject to warranty anymore.

Permissible fue l f or the Pe lling boi le rs
The boiler is designed for burning wood pellets with a diameter of 6mm and a length
of 10-30mm. In exceptional cases, by inserting additional grid as an alternative can
also be used dry wood. We do not recommend a continuously burning of wood for
more than 30 days.
The pellets quality is derived from the EN 303-5: 2012 Standard (Table 7. Water
content les than 12% according to DIN 51731-HP5, DINplus certification program and
ÖNORM M7135-HP1 or ENPlus-UNI EN 14961-2, UNI EN ISO 17225-2 class A1 or A2.
6mm diameter, length 10-30mm)
Particular attention should be paid to the quality of wood pellets. Low-grade
pellets can cause malfunction of the boiler.
Safe ty in struct ion s f or boil er room
The boiler room must be made according to current regulations, especially regarding
fire protection. No flammable material should be stored in the boiler room.
The room where the boiler is installed must be frost-resistant.
The boiler should not be exposed to cold or freezing temperatures. Extreme cold
temperatures can cause mailfunction and unexpected behavior of electronic
components.
Fresh air su pply
For combustion of pellets and normal work boiler needs fresh air. The room in wich the
boiler is installed must have an opening for fresh air supply. The recommended
minimum dimension is 30x15cm.

2.4 Obligatory informing
Everyone who operates with the boiler must read the instructions before using it, in
particular, the chapter ’’Safety Instructions’’.
This applies especially to persons who occasionally work on a boiler, for example,
cleaning and maintaining boilers. This manual should always be kept near the installed
boiler.
Pay particular attention to the applicable local standards and guidelines. All
local laws must be respected during installation, as well as standards and
norms that are in force in the country where the boiler is installed even
though it is not listed in this manual.
The Installation can be carried out only by persons (service technicians) who
are trained/educated and have a license for this job.
The central heating system must be properly calculated and dimensioned.
The chimney should be calculated and made according to EN 13384-1. The
chimney must be thermally insulated to prevent condensation.
Storage of pellets can be done only in places that are dry and free from
moisture.
In certain countries, it is necessary to measure the emissions of gases by an
authorized person during the first commissioning.
2.5 Safety devices
Boiler is equiped with safety devices that in case of unexpected situations
stop the power supply and thereby stop the operation boiler.
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 fan failure, failure
of the motor for auger, or the ignition.
Fuse F4A 250V: Fast fuse, protects the boiler from large voltage changes of electricity
and short circuits inside the boiler.
Safety limiting thermostat (STB): intervenes by breaking the circuit in the boiler
(automatically stops motor of the auger and exhaust gasses fan) if the boiler
temperature reaches the limit of 95°C.
Vacuum switch: intervenes in case of low underpressure in burnerroom(open door,
chimney jammed).

Water temperature indicator
Regulation on the boilers ''Pelling'' is most important electronic component. It is
consisted of key controling modul set under the cover of the boiler and controling unit
with display set on the front side of the boiler. With controling unit it is possible to
control functions of the boiler and also to check information about present state of the
boiler.
Due to the possibilty to work in 5 (five) different powers, regulation can satisfy needs
to increase or decrease heating by automatic adjustment of power.
If there is a need to increase power, this is registered by regulation and regulation
gives a signal to increase power by adding more pellet as well as proportional increase
of air flow in the burning basket.
When desired temperature is reached (need for heating energy is satisfied) regulation
is decreasing power ( modulates ), or when room thermostat gives signal that set
temperature is reached, boiler then goes into shut down (if mode STAND-BY is ON).

4.2 Principle of boiler operation
Principle of the boiler operation is very simple.
When button for start is pressed boiler goes into IGNITION MODE. START is
displayed, and after that PELLET IGNITION. Usually this phase lasts for 5-15 minutes
depending on type of the boiler and pellet quality. At that point dosing system is
activated, igniter and suction fan. Dispenser is making initial dosing of pellet into
burning basket. At the same point igniter starts to ignite pellet and suction fan is on
and is making necessary underpressure needed for combustion. When temperature
sensor for flue gasses detects that temperature in the chimney has reached necessary
value, regulation then changes working mode of the boiler into FLAME
STABILIZATION.
This phase (FLAME STABILIZATION) lasts for 2-3 minutes (depending on the type
of the boiler) and in this phase igniter goes off. After flame stabilization, boiler goes
into the normal working mode and changes power from power 1 to set power. On
display is written WORK. On the right side set power is displayed and in the last
