heat up the heat carrier (usually water) that circulates in the heating
sysytem.
Burner is a device used for burning various fuels
Feeder is a part or set of devices designed for delivering various fuels to
the boiler
Biomass in energy production terms, it is a source of primeval energy
consisting of different plant or animal substances which have been
biodegraded. its use is not limited within the legal system.
Pellet is a burning material that comes from the pressed wood waste,
mainly wood dust,chip, woodwork or lumbermill waste. it can also be
produced from bark, straw,sunflower or other organic materials. pellet is
delivered in the form of granules or rolls

1) Automatic control of the boiler can adjust:
źboiler temperature
źcentral heating circulation temperature
źhot water temperature
źroom temperature
źtemperature of return water from central heating (boiler exchanger
protective feature)
źignition time (depending on type of fuel)
źfuel feeder operation time
źfeeder and vent manual control time
źautomatic burner power modulation (fuzzy logic)
źautomatic air feed (lambda sensor module)
2) Temperature sensor
The STB mechanical protection is situated inside the boiler and prevent
o
the heating system from overheating. it is set by default at 95 C.
if temperature exceeds 95, the vent is turned off. at the same time central
heating hot water pumps come on and the mixer valve opens.
3)Fuzzy Logic control (advantages):
źadvanced algorithm
źreduces fuel consuption and lowers the amount of sooth
and contamination in the boiler
źenhanced boiler working temperature stability- eliminates
condensation in the boiler (sweating of the boiler)
źcombustion chamber temperature is high and stable which lowers
carbon oxides emission.
4) Lambda sensor
The sensor continiously adjusts the amount of air in order to provide
the most efficient operation of the boiler and minimise the carbon oxide
emission under the given boiler load, fuel type and weather conditions.
5) Fumes temperature sensor
The sensor is situated in the boiler flue. it allows to control the fumes
o
temperature. if the temperature exceeds 250 C, the vent automatically
shuts down until the combustion temperature drops.
6) Mixing valve acutator
With this device you can adjust the set heating circle temperature
in the central heating system, keeping the constant boiler temperature.
The temperature is calculated from the heating curve in relation to
the outside temperature.
The default fuel of boilers equipped with a screw feeder or retort or BIO
burner is hard coal conforming to the parameters outlined in norm 82/G
97001 – 3:
• coal type: 31 or 31.1
• calorific value: 26MJ/kg
• humidity: ≤ 15 %
• ash content: ≤ 10 %
• volatile matter content: ≤ 28-48 %
• sulfur content: ≤0.6%
• softening point of ash: ≥ 1150 ºC
• agglomerating capacity: <10
• granulation 5-32 mm
• dust content <10%
2) Pellets conforming to the parameters outlined in norm EN 14961-2
(C1)/ EN 14961-3(C2):
źcalorific value:16,5- 19 MJ/kg
źash content: 0,7 %
źdensity ≥ 60
źdiameter: 6 ± 1 mm; 8 ± 1mm
źlength: 3,15 ≤ L ≤ 40
ź humidity: 10 %
The fuel should be clean and not contain rocks, pieces of wood etc.
With manual stoking, the fuel is deciduous under 20 % humindity and coal
of OI sort. it is not advised to use coniferous logs as they produce a lot of
soot in the boiler, requiring it to be cleaned often.

In Poland, all the soild fuels boilers should be made in accordance with
PN- 87/B-02411 Norm „Soild fuels boilers”. the have been divided into two
categories.
1) For small boilers under 25 kW, the following requirements should be
met:
• the boiler should be placed in the central position to the heated
rooms and in a seperate room.
• the floor surface should be inflammable. if the floor is flammable,
it should be covered with steel metal sheet of 0,7 mm thickness and
exceed the boiler contour by at least 50 cm. the boiler should be placed on
inflammable base of 0,5 cm above the floor and secured by steel angles.
• the boiler room can be lit naturally as well as artificially.
• the location of the boiler in the room should enable free access to
the boiler during cleaning and maintenance works. The distance between
the back of the boiler and a wall should be at least 70 cm, the side of the
boiler and a wall should be at least 100 cm and the front of the boiler
and a wall opposite should be at least 200 cm;
• the height in a new building should be at least 220 cm. in old
buildings the the boiler room should be at least 190 cm high as long as the
ventilation inside is sufficient (supply- exhaust ventilation)
• supply ventilation should be provided by an open slot of 200 cm2 in
diameter and placed up to 100 cm over the floor surface.
• the exhaust ventilation should be provided by an exhaust duct of
14 x 14 diameter and made from noncombustible material. its outlet
should be installed under the ceiling of the boiler room. the exhaust duct
should lead out over the roof and placed in the close vicinity of the
chimney. no shut down equipment can be installed on the duct.
2) Boiler rooms of heating power greater than 25kW should meet extra
requirements, such as:
• the distance to the far-most chimney, at gravitional draught, cannot
exceed 50 cm of the chimney height.
• the fuel and slag store should be located by the boiler room. The
storing height up to 220 cm with a 50 cm free space above it.
• the equipment for vertical and horizontal delivery of the fuel
and slag should be considered.
• the fuel store should be equipped with natural ventilation that
allows for full airing once an hour in the fuel store and three airing circles
an hour in the slag store.
• the entrance door to the boiler room should be fire- resistant
(0,5 class of fire resistance), the minimum width 80cm and should open
outside. the door should have a handle- free system when opened from
the inside and have a door handle when coming inside
• the requirements for the ventilation are the same as those for the
boiler rooms of lower power; additionaly, in the boiler rooms of power
greater than 400 kW, the supply exhaust ventilation should be
accompanied by mechanical ventilation that can be periodically activated
when feeding the fuel and removing slag. it must also be able to provide
10 airing circles an hour
• natural lightning which can light the front of the boiler should be
considered in the room. the total surface of the windows should equal at
least 1/15 of the floor surface; half of the windows in the room should
open; the electrical lightining and electrical socket of max. 24 V should
also be located in the room
• inspection chamber that will allow cooling water should be located
in the floor; its capacity should equal the water capacity of the biggest
boiler but not exceed 2m3
• in the boiler room all the heating pipes should be insulated
The placing of the boiler together with the minimum distance
requirements is presented in the boiler room schematics (8.1)
ATTENTION!
The mechanical exhaust ventilation should not be
used in the boiler room
! !
ATTENTION!
Correct fresh air infeed to the boiler room will
ensure efficient fuel burn.
! !
ATTENTION!
Ensure that the carbon dioxide level in the room
is not too high.

Description 8.1 Minimal requirements for the boiler room
the SD DUO and SD DUO BIO boilers. the boilers do not require special
base and need to be leveled with adjustable feet. the boiler must be set
in the vertical position.
The boiler must be placed on a flameproof pad that exceeds the boiler
outline by 2 cm. if the boiler is located in the basement, it is recommended
that it is placed on a base of at least 5 cm thick. the bearing of the floor and
the fire hazard conditions are the key elements of choosing the right
location for the boiler i.e:
• 20 cm from any flammable materials
• 40 cm from any flammable materials of C3 flammability
• 40 cm from any flammable materials of unknown flammability

The important element of installation is correct setting and levelling of

2018
1. Check that four adjustable feet
have been provided
2. Level the boiler in relation to
the floor (if the position of the
boiler is level, there is no need
for the feet)
3. Place the feet into the
dedicated slots
4. Level the position of the boiler
ATTENTION!
If the boiler is not levelled properly it can be
damaged.
! !
ATTENTION!
The boiler must not be placed in a damp and wet
room as the enhanced corrosion process will
shortly damage the boiler.
! ! The connecting of the boiler to the central heating system should be
contracted to a producer- certified company. this procedure should be
confirmed in the warranty card which is attached to this manual. the boiler
must be connected according to the manufacturer's guidelines
and this manual.
