2. PRODUCT DESCRIPTION
The BURNiT Pell ECO pellet burner for
hot water boilers is designed to burn
only and exclusively wood pellets and it
is intended to heat up heang boilers.
The built-in control unit and automac
cleaning funcon ensure the automated
operaon of the burner and opmal
burning of the fuel.
2.1.Design.
The burner is made of high-quality
stainless steel able to withstand
temperatures of up to 1150°С. The
burner must be installed on a heang
boiler.
The burner consists of two parts:
combustion chamber and air jacket.
Longitudinally, under the housing, there
are air jacket, fuel ignition heater, fan and
control unit. On the upper part of the
burner there is a feeder chute to which
the pellet auger is aached. The housing
of the burner has been designed to
meet all regulatory safety requirements
(no sharp or protruding elements) with
operang temperature not exceeding
50°C.
The combuson chamber consists of two
parts:
Ember resistant outer tube and inner
combustion chamber with holes for air
intake along its entire length, opening
for fuel ignition heater and opening for
photosensor.
Between the two parts there is a gap
which provides for free circulation of the
air necessary both for cooling and oxygen
supply into the combustion chamber.
The feeder chute allows 360° rotaon
for its best convenient posioning
when connecng the pellet auger to the
hopper.

2.2.Burnersafetydevices
•Elbow-shape feeder chute. The
geometrical shape of burner feeder
chute prevents backre entry from
burner into pellet hopper.
•Thermostac protecon (80°С). The
thermostac protecon is ed on the
feeder 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, high
current, etc.), the overload is borne by
the electrical fuse ed on the main
control panel of the burner (10 А).
•Power interrupon. 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. FUEL
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 declaration
and certificate 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 entire heating season
for example), ask your supplier
to provde accurate and true
information about the storage
conditions.

We recommend to use pellet with size of
6 - 8mm. Density 600 - 750kg/m3 heang
value 4.7 - 5.5 kWh/kg. Ash content – less
than 1% and moisture content up to 8%,
EN 14961-2:2011.
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 2 below contains the
parameters which we recommend
that you take into consideraon when
choosing fuel for your „Pell ECO” burner.
4. TRANSPORTATION OF THE PELLET
BURNER

unloading of the device appropriate
safety equipment must be used in
accordance with Direcve 2006/42/SE.

8. BURNER OPERATING
8.1. Ignion.
Aer the start up of the burner from
the control panel, the main pellet auger
conveys certain amount of fuel from the
pellet hopper to the burner. This specic
amount of pellets is set by the installer
and depends on the fuel characteriscs.
Fuel falls directly into the combuson
chamber. Into combuson chamber the
fuel is ignited by hot air.
8.2.Burning.
The burning process takes place in the
combuson chamber. Flame intensity
is monitored by a photosensor which
monitors the burning and feeds data
into the control unit which enables the
starng or stopping of the combuson
process, if necessary. The output of the
burner is determined by the intervals
preset on the control panel taking into
account the heang value, size and
density of the pellets.
8.3. Automaccleaningsystem.
The “Pell ECO” pellet burner is equipped
with innovave automac cleaning
system for the combuson chamber.
Thanks to a powerful fan built in the
burner body, air is being blown in at high
speed and rate thus removing all residues
– ash, noncombusble inclusions, etc.
built up into the combuson chamber
of the boiler. These automac cleaning
cycles connue depending on the
parameters set by the command block.
The cleaning cycles can be addionally
adjusted as well as their repeat rate
depending on the load of the burner.
8.4. Installer prescripons regarding
burnerservicingandmaintenance
Before the heang season it is mandatory
to check up and clean the burner and its
components.
It is mandatory to clean up the
combuson chamber of burner and
movable grate. In case of combuson
chamber of burner and movable grate
orices clogged by non-combusve
material, those should be released using
a bodkin. Clean thoroughly the inner
combuson chamber using the scraper
brush to remove all deposits on the
metal surface. Use a vacuum cleaner to
remove all sand and ashes from inside
the combuson chamber. Check integrity
of gasket between outer combuson
chamber and closing hatch, replace if
compromised.
It is mandatory to clean dust o main

8.5. Important recommendaons for
long-lasngandcorrectoperaonofthe
boiler
- For assembly and installaon of the
burner follow the requirements in this
manual.
- Use only recommended in this manual
fuel.
- Disassemble the burner from the boiler
body before clean it. Depending on fuel
and burner sengs, clean the pellet
burner once a month.
- User`s training for operaon and
maintenance of burner is performed by
an authorized installer or service shop.
