2. PRODUCT DESCRIPTION

WBS Acve boiler is with built-up

controller and electric fan for forced air

feed, for ring solid fuel - rewood , Class

B wood briquees or coal. Designed to

sasfy the heang demands of medium

to large sized spaces. They are engineered

for burning solid fuel only and provide the

opon for ng pellet, oil or gas-red

burners.

Set BURNiT WBS Active – Pell: tested

according to European standards

EN 303-5, class 5.

2.1. Descripon of WBS Acve

•Design. Boiler body is made of high-

quality boiler steel sheets with thickness

of 5 mm for the combuson chamber

and 3 mm for the water mantle.

•Built-up controller. The electronic

control unit controls the operaon of

the ue fan, the circulaon pump of

the central heang and the pump of

the domesc hot water system (DHW).

The power of the fan is regulated in

relaon to the fuel consumed and the

momentary chimney dra.

•Ecient. The ue gas makes a three-pass

movement around three water-lled

barriers in the combuson chamber on

its way to the chimney. This way the

gas is cool when it leaves the boiler and

its energy has been transferred to the

water in the mantle. The water mantle

embraces the combuson chamber

in full to ulize the emied heat most

eciently. To keep from losing heat into

the ambience, the boiler is insulated on

the outside by 50 mm high-temperature

wool.

•Reliable and safe. The heat exchanging

tubular grill is protected by a replaceable

metal grate. A complex of safety devices

provide for the safety of the appliance.

•Versale. Designed for ring wood

with opon for adapng to other fuel

types by mounng a gas, oil- or pellet-

red burner on the specially designated

ange located on the lower door.

• Fuel loading door

• Cleaning door (combuson chamber)

• Air aps for feed-in air adjustment

• Dra regulang ap, mounted on ue

end

• Safety heat exchanger

• Safety devices of the boiler

2.2. Descripon of pellet burner

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.

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

TECHNICAL PASSPORT. INSTALLATION and OPERATION MANUAL

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.

Diagram 2. Pellet burner Pell design

• Built-in controller.

The main control unit, located in the

burner, manages the enre heang

process. Controler funcons:

Controler funcons:

1) fully automated ignion and pellet

feed;

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

mes over 24 hours at equal intervals),

programmable start me;

3) controls the operaon of the

circulaon pump of the central

heang;

4) controls the operaon of the pump of

the domesc hot water;

5) opon for control by room thermostat;

6) mer;

•Photo-sensor - monitors the power of

the burner ame

•Internal auger

• Dry contactless resistance heater

assuring ignion of fuel

•Innovave cleaning system of the

combuson chamber

•Air feed fan, step-regulated (0% to 100

%).

2.3. 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

TECHNICAL PASSPORT. INSTALLATION and OPERATION MANUAL

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 below contains the parameters

which we recommend that you take into

consideraon when choosing fuel for your

„Pell” burner.

doors and the boiler burning

uncontrollably.

7. SETUP OF THE HEATING BOILER AND

BURNER

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.

Diagram 4. Boiler size and chimney

parameters

TECHNICAL PASSPORT. INSTALLATION and OPERATION MANUAL

The proper funconing of the chimney

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 threeplied 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.

The inner diameter of the chimney

depends on its real height and the power

capacity of the boiler (see diagram 4).

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.

Data in the tables are for

indicave purposes.

Draught depends on the

diameter, height, uneven secons

along the chimney surface and

dierences in temperature of

combuson products and outside

air. We recommend that you use

chimney ed with ue terminal.

Heang specialist must calculate

the precise sizing of the chimney.

7.2 Connecng the safety heat exchanger

Such connecon must be

performed by a technician /

service shop authorized for such

operaons.

The heang boiler is equipped with

safety heat exchanger (cooling circuit). It

connects to the water system through a

thermostac valve. In case of overheang,

the thermostac valve feeds in cold water

from the water mains which passes

through the heat exchanger and absorbs

the heat in the boiler. The water is then

discharged into the sewage system. This

arrangement ensures safe evacuaon

of the excess heat without the need for

addional energy. This guarantees that

the water in the boiler will not exceed the

maximum safe level of 95°C.

Such connecon must be

performed by a technician /

service shop authorized for such

operaons.

When the boiler is connected to a heang

system, it is mandatory to install a 3 bar

relief valve and expansion vessel. No shut-

o ngs may be installed between the

relief valve, expansion vessel and boiler.



It is mandatory to install a three-

way valve (Laddomat or similar)

or a four-way mixing valve which

to ensure that the temperature

of the heang medium fed into

the boiler from the heang

installaon is at least 65°С.
