2. PRODUCT DESCRIPTION
The BURNiT Pell BIO 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, automac cleaning
system and internal pellet auger 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:
combuson chamber tube and
external tube with sheet metal mantle.
Longitudinally, under the housing, there
are blow chamber, fuel ignion heater,
fan and power supply. 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
tubes:
Ember resistant steel tube inside the
burner with holes for air intake along
its enre length, opening for the hot air
from the fuel ignion heater, opening for
photosensor.
Outer stainless steel tube. Between the
two tubes there is a gap which provides
for free circulaon of the air necessary
both for cooling and oxygen supply into
the combuson chamber.

•Air feed fan, step-regulated (0% to

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. The energy output
from wood and sunflower pallets.Is very
high.This undoubtedly makes pallets
made from Sunflower seed the bio fuel
of the future.As a comparison, burning
two kilos of sunflower pallets is equal ,in
terms of energy output, to burning a liter
of liquid fuel.
Sunflower pallets are made from
sunflower seed husks, which are a
byproduct generated by oil mills and
various enterprises for the production
and procesing of nuts.The technology
used to produce them is common to the
one used to produce wood pallets.
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.
i
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.
-forsunflowerpallets:
We recommend pallets with a diameter
6-8mm, density 500-650 kg/m^3 and
calorific value 4.-5.2 kWh/kg. Ash content
- no more than 3-4 % and moisture up to
11%.
The optimal density of the pallets, which
guarantees their quality is in the range
525-625 kg per cubic meter. The moisture
contained in the pellets must not exceed
11%. Make sure that you store your fuel
in a dry and airy place.
The optimal quantity of ash in the pallets
is <= 3%. Said quantity contributes to
how often you need to clean your burner.
- forwoodpallets:
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 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-A” burner.

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.
The fed-in quanty of pellets is conveyed
from the auger conveyor built in the
burner to the combuson chamber
where it is being ignited using hot air.
8.2.Burning.
The burning process takes place in
the combuson chamber and, aer
it has been fed into the combuson
chamber, the fuel is then transported
from the internal auger conveyor to
the combuson chamber in porons.
This allows for constant and opmal
burning rate of the fuel . 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” pellet burner is equipped with
innovave automac cleaning system
for the combuson chamber. Thanks to
a powerful cleaning motor 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 last several seconds and 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 using the
scraper brush from the maintenance kit.
In case of combuson chamber 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.
