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.
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

• 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%


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%., 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.
The opmal pellet ash content is ≤ 1%. This also
provides for less frequent cleaning intervals for the
burner.
The table below contains the parameters which we
recommend that you take into consideraon when
choosing fuel for your Pell burner.
4. TRANSPORTATION OF THE BOILER
We recommend to transport the heang boiler to
the installaon site in its packaging placed on the
pallet. During transport and installaon, depending
on the weight, suitable safety devices should be
used in accordance with Direcve 2006/42/EC.
When transporng items weighing more than 30 kg,
the use of pallet jack, fork truck or other hoisng
devices is a must.
Product must be in original packaging following
the instrucons on the label - to be protected from
adverse weather condions (snow, rain and dust)
from the shocks, and other acvies likely to cause
damage. In case of malfuncon of the fan or the
motor drive (noise, fricon) or failure of high-tech
elements such as broken controller-screen, contact
your nearest authorized service center for repairs
and maintenance.
The boiler is securely fastened with fasteners to a
wooden pallet.
Important: When installing the boiler,
the wooden pallet onto which the
boiler is placed must be removed by
unscrewing the bolted connecons

6. SETUP OF THE HEATING BOILER

The assembly, installaon and set-
up of the boiler must be performed
by a technician authorized for such
operaons.
Installermustindicatetotheuserofthe
installaon the minimum clearances
fromammablematerialsandliquids.
Requirements:
- Boiler room must be frost-proof;
- Boiler room must allow for connuous access of
air necessary to maintain combuson;
- Boilers must not be placed in inhabitable rooms;
- All boiler rooms must have correctly calculated
vent depending on the boiler output. The vent
must be protected by means of a net or grate.
The size of the vent is calculated according to the
formula:
А=6,02Q- where:
А – area of the vent in cm2,
Q – boiler output in kW
- Remove the packaging without pollung the
environment
- Observe building supervision instrucons, in
parcular the exisng Ordinance on combuson
devices and storage of combuson materials, on
building requirements applicable to installaon
sites and on venlaon;
- The boiler must be placed on a foundaon whose
surface area is larger than the base of the heang
boiler according to diagram 1;
- The boiler must be placed in a posion which allows
for the easiest possible cleaning and servicing;
- Installaon must be carried out according to
installaon diagram 1 which shows the boiler
housing;
- No objects made of ammable materials or liquids
may be placed on/near the boiler;
7.NSTALLATION OF THE HEATING BOILER
7.1.Connecngtheboilertoachimney
Boiler-to-chimney connecon must always comply
with the exisng standards and rules. The chimney
must provide sucient draught for evacuaon of the
smoke under any condions.
The proper funconing of the boiler requires
adequate sizing of the chimney itself since the
draught it produces aects combuson, boiler’s
output and life span.
The draught created by the chimney is in funconal
relaon to its cross-secon, height and the
roughness of its interior walls. No other appliance
may be connected to the chimney serving the boiler.
Chimney diameter must not be smaller than the ue
outlet of the boiler. Flue outlet must be connected
to the chimney opening. In terms of mechanical
properes, the ue outlet must be sturdy and
properly sealed (to avoid gas leak) and allow for easy
access for cleaning on the inside. The inner secon of
the ue outlet must not be greater than the eecve
secon of the chimney and must not narrow. Avoid
using elbow joints.
The chimney cleaning opening has to be in its
lowest part. The chimney’s wall has to be three plied
where the medium layer is from mineral wool. The
thickness of the insulaon is not less than 30 mm
when the chimney is seng up inside the house
and the thickness is 50 mm, when the seng up is
outside.
Please entrust choosing a chimney and its installaon
by a qualied professional. The required distance
between the boiler and the chimney is 300-600 mm.
Draught regulator (1) must be installed at least 600
mm from the joint (connecon).
Theuseofflexiblemetaltubesofstainless
steeloraluminummaterialisforbidden!

from temperature shock during cold installation,
as well as the appearance of condensation and
accumulation of tar on the internal combustion
chamber. As for products working with fuel - wood,
briquettes, the three-way valve must open at a
minimum of 55 degrees, and for pellet equipment
- 45 degrees.

9.1. OperationofboilerPellEasy-Novaon
Ignion.
After starting the boiler up from the control panel,
the main pellet auger conveys certain amount of
fuel in Combustion chamber. This specic amount
of pellets is set by the installer and depends on the
fuel characteriscs. This specific amount of pellets is
being ignited using hot air.
Burning.
The burning process takes place in the combustion
chamber of the boiler, as the fuel portions are dosed
(measured) at regular intervals by the integrated
auger. This achieves optimum combustion. The
boiler performance is controlled and operated by a
temperature sensor that measures the temperature
of the water jacket (mantle) and a temperature
sensor that measures the temperature of the
exhaust gases. Ignition and stop are controlled by
the exhaust gas sensor, which gives information to
the control unit. The power is determined by the
adjusted maximum temperature in the boiler, as
shortly before reaching it, it starts modulating.
Selfcleaningsystem.
The boiler has a self-cleaning feature that allows
self-cleaning of the combustion chamber. At regular
intervals, the fan starts on maximum power to clear
the residual ash in the combustion chamber. Thus
ensuring a long and effective combustion process.
9.2. Important recommendaons for long-lasng
andcorrectoperaonoftheboiler
- For assembly and installaon of the boiler follow
the requirements in this manual.
- Use only recommended in this manual fuel.
- Use only recommended in this manual Combustion
chamber before clean it. Depending on fuel and
burner settings, clean the pellet burner once a
week.
- User`s training for operaon and maintenance of
boiler is performed by an authorized installer or
service shop.
