1. INTRODUCTION
1.1. Obligations of the user and guidelines concerning safety
To assure operational safety and maintain optimum operation
of the equipment:
• read the manual of the boiler, controller, feeder and observe
their guidelines,
• the manual should be kept and stored in a safe place in the
boiler room allowing using it during any moment of boiler
operation,
• ensure that it is never operated by children or persons who
have not read the contents of the manual and adults with
disabilities preventing them from the safe operation,
• the system should be made in compliance with the applica-
ble regulations and in accordance with the rules and recom-
mendations contained in the manual,
• before setting and connecting the boiler check whether all
components are in good working order and whether the
boiler has a complete equipment for servicing and cleaning,
• the boiler should be cleaned on regular basis, at least once
per week, removing a layer of deposited soot and ash, which
reduces the eciency of the boiler,
• ensure continuous access to the equipment,
• avoid exceeding water temperature in boiler over 95°C,
• maintain operating pressure not exceeding 1.5 bar.
NOTE! Boiler installation in accordance with the applicable
standards and regulations and rst start-up should be car-
ried out by a qualied installer.
1.2. Selection of correct power of the boiler
Nominal power of purchased boiler (that is maximum ther-
mal eciency, which can be reached during continuous use
maintaining the eciency declared by the producer) should be
selected in a way corresponding the real demand for thermal
energy even in case of occurrence of very low temperatures.
Do not purchase boiler with power higher than this planned
in the design. Selecting boiler with too high power will result in
higher fuel consumption and lack of full control over the com-
bustion process and therefore higher operation costs, while too
small boiler will not ensure sucient power necessary to heat
up the building.
Approximate boiler power can be calculated using a pow-
er calculator on our website www.pereko.pl Furthermore, you
should also consider: thickness of walls and insulation, the
thermal permeability of rst x joinery (including: tightness of
windows and doors, type of window panels used) and climatic
zone, where the heated building is located.

2. TECHNICAL DESCRIPTION
2.1. Intended use
Steel heating boilers KSR BETA PELET are intended for instal-
lation in the central heating water systems in single-family
houses, garages, maintenance rooms etc. These boilers belong
to a group of low-temperature boilers and are not subject to
registration in the regional Oce of Technical Inspection. They
are intended for operation in water distribution piping of the
gravity hot-water systems or in open systems with forced circu-
lation, which are equipped with protections in compliance with
the requirements PN-91/B-02413 applying to the protections
of the open water heating system (considering the Regulation
of the Minister of Infrastructure, Journal of Laws of 2009 no. 5
item 461).
2.2. Design description
2.2.1. The set includes
• Boiler body (on pallet)
• Charging hopper (on pallet)
• Burner with feeder (packed in cardboard box)
2.2.2. Water casing
KSR BETA PELET heating boilers are made of steel sheet P265GH
intended for production of the pressure equipment operating in
the elevated temperatures. Heat exchanger sheets are welded
from both sides and body sheets are reinforced with supports.
Location of convection ducts allows cleaning through the upper
doors. Ash and soot are removed through bottom doors. Design
solution, that is the use of three-draught design of the furnace,
ensures ecient reception of heat.
2.2.3. Doors
The boiler is equipped with top doors intended for cleaning,
central inspection doors and bottom doors, with pellet burner
and they are intended for removal of ash formed during the
combustion process.
2.2.4. Water jacket
The water jacket is a space lled with heating medium - water.
The structure is made of steel sheet P265GH for pressure equip-
ment intended for operation at elevated temperatures.
2.2.5. Thermal insulation panels
Insulation panels xed on the surface of the water casing lim-
its heat losses to the environment. They are made of aesthetic
panels made of a zinc-plated metal sheet, painted with powder
paint ensuring high anti-corrosion protection. The modules are
lined with a mineral wool from the inside, which is used as an
insulation material.

2.2.6. Electronic controller
Microprocessor controller, installed in upper front part of the
boiler allows programming temperature of boiler operation and
programming changes of temperature of its operation at any
time.The controller is also responsible for the so-called blowing
of the furnace chamber.The controller is also equipped with op-
eration control sensor and sensor of emergency boiler shutdown
after exceeding water temperature 95°C. Detailed information
you will nd in the“User’s manual of microprocessor tempera-
ture controller”, enclosed in the boiler documentation.
2.2.7. Set of feeder with burner
The unit consists of two modules: burner driven by the mo-
toreducer, which is installed in the bottom doors or on the side
of the boiler and pellet feeding tube with drive and transport
screw. Its task is to take the fuel from the container and feed it
automatically to burner part. Unit design allows quick assem-
bling and disassembling.
2.2.8. Water connections
Water connections are intended for connection of boiler to the
central heating system. Size of supply and return connection
- G 1 1/2”internal thread.
2.2.9. Flue with a damper
Flue with rotary ue gas damper is an integral part of the boiler,
which discharges ue gas towards the chimney ue.
2.2.10. Flue gas swirlers
Flue gas swirlers are located inside the convection ducts to swirl
ue gas stream, what has an inuence on the increase of e-
ciency and the boiler power. The swirlers should be removed in
case of weak chimney draught.

2.5. Fuel
Wood pellet is a primary fuel used in the KSR Beta Pelet: PN-EN
ISO 17225-2:2014 – class A1. Fuel used for combustion in the
pellet-red boiler should have sucient caloric value > 17 MJ/
kg, be dried (moisture content ~ 10%) and have size recom-
mendedbythe producer (6±1mm and8 ±1mm). Useof moist
or too large fuel can lead to locking in the feeder and serious
failure of the boiler. Ash content should be lower than 0.5%,
the unfavourable chemical composition of the fuel can result in
sintering and formation of large amounts of dust and soot and
increased fuel consumption.Times given in the table on page 14
apply only to operation with suitable fuel.
2.6. Equipment
Prior to the boiler setting you should check the presence of addi-
tional tools and operation of the instrumentation.The complete
set should include: burner with a feeding system, fuel container,
electronic controller, brush, hook, ash shovel, drain cock, fuel
swirlers.
3. BEFORE START-UP
3.1. Boiler room
• It should be a separate room with height not lower than 2.2
m in the newly constructed building (in the already existing
buildings the allowable height equals to 1.9 m).
• It should have articial lighting installed and have natural
lighting as far as practicable.
• It should have gravity ventilation in good working order,
including:
1. air-supply duct in the external wall with cross-section
not lower than 50% of chimney cross-sectional area on
height maximum 1 m over the ooring or not lower than
200 cm2for boilers with power up to 25 kW or 400 cm2
for boilers over 25 kW,
2. 2. separate air-exhaust duct on the internal wall with
cross-section not lower than 140x140 mm with an out-
let located under the boiler-room roof near the chimney.
NOTE! It is forbidden to use mechanical exhaust ventilation
in the room where the boiler was installed.
• Floor gully and oor with 1% slope towards the outlet
should be planned in the central part of the room.
• Flooring and walls in the whole room should be made of
non-combustible materials.
• The doors to the boiler room should open outwards.
3.1.1. Method for boiler setting
The boiler requires non-ammable ooring, in form of a foun-
dation, but it is allowed to place it on non-ammable wall base
with height not lower than 50 mm. The boiler should be placed
in a way ensuring free access to the equipment, allowing its
cleaning and maintenance. Therefore, while setting the boiler
it is recommended to maintain minimum distances from the
individual walls:
• distance from the front of the boiler to opposite boiler room
wall should not be smaller than 2 m,
• the distance of boiler side from the wall of the boiler room
should be lower than 1 m,

9

• the distance of rear part of the boiler from the wall of the
boiler room should be equal to at least length of the connec-
tion, that is 0.25 m.
3.2. Connection to chimney
1. It is necessary to prepare stand-alone, tight chimney ue,
which will be used for ue gas from the boiler.
2. The ue should be placed at least 1.5 m over the roof ridge
to avoid the occurrence of backdraught. The intersection of
the ue should be appropriately selected for the boiler pow-
er and height of the chimney. Approximate calculations of
chimney height and intersection can be carried out using
a chimney intersection calculator available on the website
www.pereko.pl Regardless of the results of the calculations
the minimum intersection of masonry chimney should not
be lower than 14 x 14 cm!The intersection of non-insulated
steel chimneys should be bigger by 20% and the chimneys
made from steel pipes should be about 15-20% higher than
brick chimneys.
3. Check condition of the chimney (preferably by a chimney
sweep) before connecting the boiler to the chimney and
check whether the chimney is free from connections of the
heating elements.
4. The boiler should be connected with chimney using a con-
nector. It is not recommended to use the connection at a
straight angle because it will cause a loss in the chimney
draught. Flue with chimney should be joined with a connec-
tor made of steel sheet of thickness 3 mm (to be purchased
from the boiler producer). We put it on the outlet from the
ue, x on the chimney and seal with high-temperature
silicone. The connector should be directed slightly upwards
from 5° to 20°. If boiler ue will have a length over 400
mm then it is recommended to insulate it with a thermal
insulation.
NOTE! Boilers should be installed in compliance with the
applicable Regulation of the Minister of Infrastructure
(Journal of Laws of 2002 no. 75 item 690 and Journal of
Laws of 2009 no. 56 item 461.) In addition, it is recom-
mended to use chimney liner resistant to corrosion: chem-
ical, pitting, intercrystalline and surface.

3.3. Connection of central heating and domestic hot water system
3.3.1. Open water installations
KSR Beta Pelet boilers are intended for feeding water distribu-
tion piping in the open central heating systems with gravity or
forced circulation of water.The system, where the boiler will be
operated, should meet the requirements of the Polish Standard
PN-91/B-02414 Heating and district heating - Protection of
