* depending on theinsulation of a building;
1. 2 Fuel
The basic fuel used with the KSW & KSW PLUS boilers is coal of the following granulation: 20÷40 mm or 40÷60
mm, with a fuel value of about 25 MJ/kg. The substitute fuel is a mixture of coke (type OI or OII) and coal type 32.1, range
nut coal class II 24/12, according to norm PN-82/C-97001-3 and a proportion of both fuels 1:1 or 2:1. The substitute fuel can
also be a mixture of nut coal (70%) and dust coal (30%). It is not recommended to burn entirely with dust coal with boilers
KSW and KSW PLUS. Other fuels not mentioned in the Instruction Manual (i.e. briquettes from hard coal or brown coal,

PER-EKO type KSW & KSW PLUS – Instruction Manual

wood, etc.), can also be used with KSW and KSW PLUS boilers. However, burning wood negativelyaffects the lifespan of the
boiler as well as its efficiency. Continuous use of wood as the main fuel leads to soot accumulation and water condensation
in the boiler and the chimney system, which results in symptoms similar to a leak.
Attention: Sustaining the temperature of the heated medium below 57°C leads to the
condensation of fumes in the convection pipes of the boiler and results in lower efficiency and soot
accumulation in the boiler. Additionally, long-term boiler activity in the above conditions leads to a quicker
pit and surface corrosion.

2. BOILER TECHNICAL SPECIFICATION
2.1 Water main body
Boilers type KSW & KSW PLUS are made of steel sheet used for pressure devices and are meant for work in
increased temperature P265GH. The sheet is 5mm thick from the inside and 4mm thick from the outside. The metal sheet
parts of the main body are welded and the flat sides are additionally strengthened with conjoining steel bars. The
convection channels from smoke tubes are situated in such a way that the cleaning is conducted via the upper washout
door. The construction of the boiler allows effective heat reception thanks to the application of fumes recurrence.
2.2 Doors
The boiler has the upper door, the loading door and the common door for the embers chamber and the furnace
(welded, made of steel or cast iron), each equipped with an incandescent plate.
2.2.1 Upper washout door
The upper washout door is used for cleaning the upper and the lower smoke tubes chamber once the fumes swirl
inserts are removed.

PER-EKO type KSW & KSW PLUS – Instruction Manual
2.2.2 Loading door
The loading door is used to fill the hearth chamber with coal and to clean the heatable surfaces of the boiler. The
door is equipped with a recurring air throttle* and an upper incandescent plate which protects the door against excessive
overheating.
* Applicable only to boiler type KSW
2.2.3 Grate and ash pan door
The grate and the ash pan chambers have got one door equipped with a flap which controls the air inflow.
2.3 Flue
The boiler has a welded flue which is responsible for transferring the fumes from the boiler to
the environment. The flue also has a smoke throttle responsible for controlling chimney draught.
2.4 Insulation panels
Located on the surface of the water main body, the insulation panels limit the boiler’s heat loss to the
environment. The panels are made of esthetic tinplate metal caskets covered with a highly corrosion-resistant powder
paint. The inside of the caskets is laid with mineral wool (type of insulation material).

3. BOILER EQUIPMENT
The boiler is equipped with tools used for cleaning and operating the boiler, as well as devices responsible for
controlling and regulating the burning process and ensuring safe and economical boiler activity.
Boiler temperature controller is a standard feature of the KSW PLUS type. The controller’s instruction manual is
enclosed separately. The boiler’s equipment includes: bimetallic thermometer 0-120˚C, release tap G1/2”, brush, hook, ash
shovel and ash remover.
4. BOILER INSTALLATION MANUAL
The boiler is delivered in the assembled state. Before setting up and installing the boiler with the central heating
system and the chimney flue, it is strongly advised to get acquainted with the instruction manual; check if all
the devices are in working order and that the boiler is fully equipped with maintenance and cleaning tools.
4.1 Boiler set up
The boiler does not require foundation. It is allowed to lay the boiler on an underpinning not lower than 50mm.
The distance between the boiler and the opposite wall ought to be at least 0,5m greater than the boiler length but not
smaller than 2m. The distance between the back of the boiler from the boiler room wall ought to be at least equal to the
length of the connector. The distance between the side of the boiler and the wall of the boiler room should not be smaller
than 1m.
The utility room in which the boiler is to be situated ought to have 2 air holes: ventilation duct with a diameter
not smaller than 50% of the chimney diameter surface, efferent duct with a diameter not smaller than 140x140mm, with
an inlet hole under the ceiling of the boiler room.
4.2 Boiler connection to the chimney
The flue is to be attached to the chimney via the connector (this product can be purchased from the manufacturer)
made from 3mm thick metal sheet, which is to be fixed on the outlet of the flue, mounted in the chimney and sealed. It is
allowed to narrow the diameter of the connector towards the direction of the chimney duct. Under no circumstances should
the diameter be extended. The connector ought to rise up slightly from ˚5 ÷ 20˚C. An appropriate height and chimney
diameter (in accordance with the PN-89/B-10425 norm) plays a significant role in appropriate boiler activity. Before fixing
the boiler to the chimney, it is advised to check whether the chimney diameter is appropriate and that the chimney is free
from other heating objects connected to the system. The technical condition of the chimney being connected to the boiler
is to be evaluated by the chimney sweep. In order to avoid the reverse draught effect in the chimney duct, the chimney
height ought to be built above the ridge and not lower than 1,5m.
ATTENTION: Boilers type KSW are to be used together with chimney insert made of corrosion-resistant steel,
making sure that the required diameter of the chimney duct is maintained.

4.3 Supplementation of the boiler with central heating water
Water supplementation can be performed from the water supply system via the release tap in the boiler by means
of elastic hosepipe which is to be detached from the boiler once the installation is filled with water and the release
tap is closed. Boilers type KSW PLUS are adapted to operate together with the circulation pump.
4.3.1 Information on terms and conditions enclosed in the PN-91/B-02413 norm
The boiler ought to be connected with the installation by means of appropriate connectors.
The heated water coming from the heating system cannot be used for other purposes than heating only and
the working pressure cannot be higher than the acceptable pressure for the application with installation
elements and devices.
The inner diameter of the safety pipe ought to be at least 25mm.
The inner diameter of the expansion pipe ought to be at least 25mm.
The safety pipe and the expansion pipes (with the exception of vertical sections) ought to be run without
bends, with a decrease of at least 1% towards the boiler; changes in directions of pipes ought to be carried
out using arcs with the axis radius of at least 2d, where “d” stands for the external pipe diameter.
The inner diameter of the overflow pipe should not be smaller than the inner diameter of the safety and the
expansion pipe.
The inner diameter of the venting and the signaling pipe ought to be at least 15mm.
5. BOILER OPERATION MANUAL
5.1 Water filling
Before lighting the boiler up, the system and the boiler are to be filled with water, according to the instructions
given by the executor of the system. The hardness of water should not exceed 20˚n. Check whether the expansion vessel
(located in the highest point in the system) has water inside it. This inspection is to be carried out during a period of few
seconds, in order to ensure that the water flows down the vessel.

PER-EKO type KSW & KSW PLUS – Instruction Manual
5.2 Ignition of the boiler
Ignition in a cold boiler should only take place after ensuring that an appropriate amount of water is in the system
and that the water has not frozen. Before the ignition, make sure that both the boiler and the whole system are in good
working order.
It is forbidden to use flammable substances for the ignition.
The ignition ought to take place gradually using wood and a small layer of coal afterwards.
For boilers type KSW
The throttle located in the lower door and the flue throttle ought to be open. The lever of the movable grate
ought to be situated in the outermost position towards the back of the boiler.
Once the fuel has been on fire, the hearth chamber can be loaded up to the bottom edge of the loading chamber
of the upper door. Afterwards, the flue throttle and the lower door throttle are to be set according to the required boiler
temperature. The recurring air throttle is to be shut during the ignition stage. The degree to which the throttle is to be
opened depends on the type of fuel. The worse the fuel, the bigger the opening of the recurring air throttle.
For boiler type KSW PLUS
Check the fitting of both the fan and the controller to the boiler’s main body as well as their electrical connection.
Connect the controller’s cord plug to the electricity socket with the voltage of 230V.

Once the boiler has been loaded with fuel and after the initial ignition (by pressing the START button) has started,
the system goes into the lighting mode. This will activate the fan which will increase its operation gradually, until finally
reaching its preset working parameters (these parameters are to be set according to the controller’s instruction manual).
After reaching the temperature of 30±2˚C the controller automatically activates the circulation pump.
In order to deactivate the controller a STOP button has to be pressed.
5.3 Burning fuels in the boiler
The fuel is to be loaded periodically until the whole chamber has been filled up. Fuel supply in the boiler lasts
around 4-8 hours (depending on the quality of the fuel used) when operating with the rated power. When operating with
lower heating power, this period is to be increased accordingly.
The burning process in the KSW boiler can be regulated manually by changing the location of the throttle in the
lower door by means of a regulated screw, or automatically, by means of an automatic draught regulator.
Opening the furnace door throttle causes an increase in the heat efficiency of the boiler. When using the draught
regulator, the regulating screw of the throttle is to be unscrewed in the way that allows the throttle itself to close the
opening. Weak light in the furnace coming from the embers shows that the furnace grate has been overfilled with ash,
which results in the decrease of the temperature in the boiler.
Deashing of the grate while the boiler is operating is carried out by repeatedly shifting the lever of the mechanical
grate to the back and towards the boiler, leaving the lever in the outermost back position.
The burning process in the KSW PLUS boiler is performed by the temperature controller.
The fan is to be turned off before supplementing the KSW PLUS boiler with fuel.
While using the boiler with the temperature lower than 60˚C, the steam coming from the fumes condenses on

PER-EKO type KSW & KSW PLUS – Instruction Manual
the sides of the boiler. During a long-term use this can result in corrosion which decreases the lifespan of the boiler.
Therefore, it is recommended to use the boiler above the temperature of 60˚C. This can be achieved by:
Choosing the boiler according to the required size of utility rooms.
Using tee or cross valves between water outlet and inlet in the boiler.
When starting the boiler for the first time or when starting the boiler from cold, a “boiler sweating” effect may
occur, making it look like the boiler is leaking. In this case, the boiler is to be ignited intensely to the temperature
of around 80˚C, in order to dry out the boiler and the convection channels. A similar procedure is to be applied
once a week in cases when the boiler persistently operates in lower temperatures.
5.4 Boiler malfunctioning
Typical problems and solutions
Problem Cause Solution
insufficient chimney draught remove every leakiness in the
chimney, the flue and the boiler door

instruction manualHumidity and excessive soot inside the
boiler (symptoms similar to a leak) maintaining lowtemperature
in the boiler
use the boiler in temperatures
of at least 57˚C
Leak to be assessed by the manufacturer Per-Eko service team repair
5.5 Maintenance instruction
Regular and meticulous cleaning of the boiler is essential for its appropriate functioning. When the deposit layer is
too thick, the boiler looses its heat reception capabilities which results in lower efficiency and may lead to a breakdown. The
boiler is to be cleaned at least once a week. The ash is to be thoroughly removed from the hearth chamber and the furnace.
Once the upper and the lower inspection cover in the rear part of the boiler has been opened, both the smoke tubes and the
fume ducts are to be cleaned and the soot is to be removed from the fume ducts.
Periodical servicing is to be carried out once a year, when the boiler is in the stoppage mode.
In order to perform the service and determine possible repairs, the boiler is to be thoroughly cleaned from all the
remains which had been left in the burning process.

PER-EKO type KSW & KSW PLUS – Instruction Manual
More serious repairs resulting from a faulty usage, ensuing breakdowns or mechanical breakdowns, ought to be
carried out immediately after having been certified.
5.6 Transportation instruction
The KSW boilers are delivered in a fully assembled state. The furnace lever is fixed in a transportation-adapted
position. For the transportation purposes, the boiler is placed on a wooden pallet and secured with plastic wrap.
5.7 Final remarks
The fundamental feature of the central heating boilers type KSW & KSW PLUS is their construction, which
guarantees high efficiency with comparatively low fuel consumption. The boilers are always accompanied with a warranty
