2. PRODUCT DESCRIPTION
Ecological and highly-ecient pellet
boiler Pell Easy is designed for ring
wood-pellets. The mantle fully covers
the combuson chamber. Eciency rate
reaching 92%. Approved in accordance
with EN 303-5, class 5.
2.1.DesignstructureofboilerPelleBurn.
Restingular body design is made of high-
quality boiler steel sheets with thickness
of 4 mm for the combustion chamber and
3 mm for the water mantle.
•Ecological. A high-end pellet boiler. The
wood-pellets used for fueling the boiler
are a renewable fuel with minimum
carbon emissions and ulmate burning
eciency.
•Automated. All boiler funcons are fully
automated – no human intervenon is
needed for the normal operaon of the
boiler. Owing to an improved algorithm
with oponal adjustment of a wide
variety of parameters, the system may
be nely tuned to any parcular heang
system to achieve opmum eciency
and fuel consumpon.
Controllerfuncons:
1)fully automated ignion and pellet
feed;
2)burnerself-cleaningfunction;
3)controls the operaon of central
heangcirculaonpump;
4)controls the operaon of DHW
(domeschotwater)pump;
5)controlsbyroomthermostat;
6)uegassensor;
• Efficient. To keep from losing heat into
the ambience, the boiler is insulated on
the outside by 50 mm high-temperature
wool. With its inteligent state-of-the-
art combustion control system the Pell
Easy boiler achieves efficiency rate of as
much as 92%
2.2. Safety devices of pellet boiler-and-
burner
A complex of safety devices provide for
the safety of the appliance. Air-feed fan,
step –regulated, controls the combuson
according to energy needs and is
maintained in opmal working order.
Independent STB thermostat shut-o the
burner and shut o the fuel feeding in
the combuson chamber in case of rising
boiler temperature.
•Thermostatic protection (80°С). The
thermostatic protection is fitted on the
auger chute. When the surface of the
feeder chute reaches 80°С, the control
stops the feeding of pellets into the
burner and signals for fault.
•Fuse. In case of electrical fault in the
system of the burner (short circuit,
current overload, etc.), the overload is
borne by the electrical fuse ed on the
main control panel of the burner (10 А).
•Power interrupon. Innovave
controller. In case of power interrupon,
all parameter sengs are stored in the
memory of the controller. Upon the

subsequent restart of the burner, the
controller resumes the execuon of
the program from the point when the
power interrupon occurred.
3. FUELS
All pellets are biomass manufactured
from common low-growing plants and
trees. The most common household type
pellets are made of sawdust and milled
wood chippings which are waste material
from wood used in the producon of logs,
furniture and other products. Wood is the
richest raw material which does not have
any impact on the producon costs of
food products or ethyl alcohol (ethanol).
The raw material is processed under high-
pressure and temperature and is pressed
to produce small-size cylindrical pellets.
The producon process may ulize so
wood material (such as sowood, pine),
hardwood (oak) as well as recycled waste
wood. Wood pellets are produced in
hammer mills or wood pellet plants.
Advantagesofwoodpellets:
Convenientstorage.
Pellet bags can be stored on a small area
in a dry garage, basement, service room or
shed.
Easyloading.
In most cases the boiler hopper needs
loading only once a week – this depends
on the hopper capacity.
Beercontroloffuelquanty.
The small size of the pellets allows
for precise fuel feeding. On the other
hand, the supply of air for reaching
opmal combuson eciency is easier
to adjust since the fuel quanty in the
combuson chamber remains constant
and predictable.
Fueleciency.
High combuson eciency is also
determined by consistently low moister
content of pellets (consistently under
10% as opposed to 20% to 60% moisture
content of the logs). Low moisture
content, controlled fuel porons and
precise air seng means high combuson
eciency and very low carbon oxides in
the ue gases.

When purchasing pellets, ask
for conformity declaraon and
cercate issued by an accredited
laboratory and make sure the
fuel meets the requirements
indicated in the manual. If you
purchase large amount of pellets
(bulksupplyfortheenreheang
season for example), ask your
supplier to provide accurate and
trueinformaonaboutthestorage
condions.
We recommend to use pellets with size of
6 - 8 mm. Density 600 - 750 kg/m3 heang
value 4.7-5.5 kWh/kg. Ash content – less
than 1% and moisture content up to 8%.,

TECHNICAL PASSPORT. INSTALLATION and OPERATION MANUAL
TECHNICAL PASSPORT. INSTALLATION and OPERATION MANUAL
EN ISO 17225-2:2014.
The opmal density of the pellets which
guarantees their quality is 605-700 kg per
cubic meter.
Pellet moisture content must not exceed
10%. Make sure you store your fuel in a
dry and well-venlated place.
