2. PRODUCT DESCRIPTION

The BURNiT Pell 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.

The feeder chute allows 360° rotaon

for its best convenient posioning

when connecng the pellet auger to the

hopper.

2) self-cleaning funcon (adjustable 1-6

3) controls the operaon of the

circulaon pump of the central

4) controls the operaon of the pump of

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

100%).

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.

INSTALLATION and OPERATION MANUAL

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.

INSTALLATION and OPERATION MANUAL

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 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 PELLET

INSTALLATION and OPERATION MANUAL

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.
