Dear Customers!
Thank you for purchasing Commo Compact 32 boiler. Please read the entire Operation Manual carefully before installing and
using your Commo Compact 32 boiler. Heating devices (hereinafter referred to as "pellet boiler s" or "boiler s") produced by
company “Alfa Plam JSC” are designed, manufactured and tested in accordance with the requirements of the applicable
European Safety Standards Directives.
This Manual is intended for the boiler users, installers, and technicians authorized to use the Como Compact 32 Pellet Boiler
. If you have any questions related to this Manual, or if you need any clarification, please contact the manufacturer or an
authorized seller of “Alfa Plam”.
Any even partial printing, translation and reproduction of this Manual is subject to the approval of “Alfa Plam”. The boiler
uses pellets as fuel. The boiler works automatically by loading pellets by the screw feeder from the pellet tank that is part of the
device located behind the boiler unit. The pellet tank r is filled from above through the designated lid. Make sure that the boiler
is properly dimensioned with regard to the heating system and the thermal needs of the facility. The device should be connected
and started by a person authorized by “Alfa Plam”.
The flame that develops in the boiler during normal combustion of wood biomass emits exactly the same quantity of carbon
dioxide (CO2) that would be released as a result of the natural decomposition of wood. The quantity of CO2obtained by the
combustion or decomposition of wood corresponds to the quantity of CO2the tree had absorbed during its life cycle and had
turned into oxygen and carbon. By using non-renewable energy sources (coal, fuel oil, gas), contrary to what happens with wood,
a much larger quantity of CO2is released into the air. Over the years, it has been accumulating and contributing to the
enhancement of the greenhouse effect. The principle of clean combustion meets all environmental protection requirements, and
“Alfa Plam” has directed all of its development and its activities towards meeting this goal.
FIRST OF ALL YOU NEED TO KNOW:
-THE BOILER IS A COMPLETE PRODUCT WHICH INCLUDES ALL ELEMENTS NECESSARY FOR THE HEATING SYSTEM,
THEREFORE YOU DO NOT HAVE ANY EXTRA COSTS, AND THESE ELEMENTS ARE:
CIRCULATION PUMP RS 30/6, FITTED ON THE RETURN PIPE. THE SECOND PUMP IS NOT REQUIRED FOR SPECIAL
HEATING (FLOOR, WITH ACCUMULATING BOILER, ETC),
18-LITRE EXPANSION TANK ENOUGH FOR 37.5 KW HEATING POWER,
AUTOMATIC AIR VENT VALVE SET ON THE HOT WATER OUTLET FROM THE BOILER ,
SAFETY VALVE INSTALLED ON THE HOT WATER OUTLET FROM THE BOILER ,
FILL AND DRAIN COCK, INSTALLED ON THE LOWEST POINT OF THE BOILER ,
NON-RETURN VALVE R5 / 4 "INSTALLED ON THE HOT WATER OUTLET FROM THE BOILER WHICH PROTECTS THE
BOILER FROM CONDENSATION.
WATER PRESSURE SENSOR IN THE BOILER , WHICH TURNS OF THE BOILER IN CASE OF TOO LOW OR TOO HIGH WATER
PRESSURE IN THE HEATING SYSTEM.
YOU SHOULD PARTICULARY BE FAMILIAR WITH THE FACT THAT THE MAIN CHARACTERISTIC AND THE GREATEST
ADVANTAGE OF THESE BOILER S IS THE INSTALLED MECHANISM FOR AUTOMATIC MECHANICAL CLEANING OF THE FIREBOX.
THIS UNIQUE PATENTED SYSTEM, WHICH DOES NOT ALLOW INCOMBUSTIBLE PELLET PARTS TO PILE UP AT THE BOTTOM
OF THE FIREBOX, IT PREVENTS THE SO CALLED "CEMENTING", AND IT DOES NOT ALLOW THE OPENING AT THE BOTTOM OF
THE FIREBOX TO CLOSE. THIS SYSTEM ENABLES:
-COMBUSTION OF LOWER QUALITY PELLET (BUT NOT THE WORST QUALITY).
-GREATER AUTONOMY OF THE BOILER OPERATION, AND IT ENABLES THE BOILER TO OPERATE FOR A LONGER TIME
WITHOUT BEING CLEANED.
YOU SHOULD ALSO KNOW THAT THERE ARE TWO LARGE ASHTRAYS IN THE BOILER WHICH GIVE A HIGHER AUTONOMY
AND PROVIDE LONGER OPERATION OF THE BOILER WHICH MEANS YOU CAN CLEAN IT EVERY FEW DAYS (DEPENDING ON THE
PELET CONSUMPTION AND QUALITY).
THE BOILER ALSO CONTAINS A PELLET TANK WHICH COLLECTS 70 KG OF PELLETS. HOWEVER, THE BOILER MAY ALSO BE
CONNECTED TO A SPECIAL, BIG PELLET RESERVOIR (TANK) INSTALLED NEAR THE BOILER FOR COLLECTING 300 - 500KG OF
PELLETS, AND THIS ADDITIONAL TANK WOULD COMPLEMENT THE OPERATION OF THE INSTALLED PELLET TANK WHEN
NECESSARY.
DUE TO THE EXTENDED HEIGHT OF THE BOILER AND DIFFICULTIES WITH FEEDING THE PELLETS INTO THE TANK, THE
BUYER MAY PROVIDE LOW LADDERS, OR IN OTHER WAY FACILITATE FEEDING THE PELLETS INTO THE TANK.
CAUTION
-The minimum installed power of the heating system must not be less than 65% of the boiler’s rated of the boiler, and the
maximum power of the system must not exceed 100% of the boiler’s rated power.
-The flue connected to the boiler must meet the requirements set in the user manual.
-To connect the appliance to the flue, do not use flexible hoses instead of flue pipes.
- Regular maintenance and care, such as cleaning the boiler, flue pipes and nozzles (pipes), are important for safe operation, and
especially for effectiveness and maintenance value of the boiler.
- Do not perform any unauthorized modification to the appliance, as any unauthorized modification will void the warranty.

TRANSPORTING AND MOVING THE PELLET BOILER
When moving the boiler , take care of your own safety.
Before transporting and moving the pellet boiler , which must be carried out absolutely safely, ensure that the forklift
truck has a carrying capacity sufficient for lifting the boiler . Avoid sudden movements and /or improvised ways to move the
boiler . Lifting, moving and repositioning your boiler can be carried out by means of rod-like boiler supports that have a thread
at one end. These supports (4 pieces) are wound up to the designated places on both sides of the boiler (Figure 1). This activity
should be carried out by 4 people. Boiler supports are delivered with the boiler !
Note:
When moving the device, it should be taken into account that it is much heavier in its front part because the boiler itself is located
in that part of the device!
ALL THE PACKAGING MATERIAL SHOULD BE REMOVED AWAY FROM THE REACH OF CHILDREN. THE MATERIALS
CONTAINED IN THE PACKAGING (BAGS, FILMS, POLYSTYRENE, ETC.) MAY CAUSE SUFFOCATION.
RESPONSIBILITY OF THE INSTALLER
The installer is responsible to check if the installation and the air supply function properly and if all the requirements
required for the installation of the pellet boiler have been fulfilled.
The installer is to ensure that the boiler is in compliance with local regulations applicable in the place where the boiler is
installed.
The boiler must be used in accordance with the instructions given in this Installation, Operation and Maintenance Manual,
as well as with all the safety standards prescribed by local legal regulations applicable in the place where the boiler is
installed.
The installer’s obligations are defined by the SRPS 10683 Standard. The installer must verify:
The type of the boiler that is being installed,

2
Whether the room in which the boiler is being installed is appropriate, i.e. minimum size of the room in which the
boiler is to be installed,
Compliance with the flue gas regulations set forth in the instructions supplied by the manufacturer of the heating
device
The internal chimney diameter, the material the chimney is made of, whether it is flat and has a regular shape,
whether there are any obstacles and barriers in the chimney,
The height and vertical extension of the chimney,
The existence and suitability of a wind resistant protective cap of the chimney,
The possibility of providing the external air intake,
The possibility of the simultaneous use of the heat source with other equipment already existing in that place.
If the above mentioned standards have been satisfied, then the installer may proceed with the installation of the boiler .
The instructions provided by the boiler manufacturer, as well as the fire prevention standards and safety standards must be
observed.
After the boiler has been turned on for the first time, the system must be put into a trial operation for at least 30 minutes in
order to check that all the required conditions have been met.
Once the installation has been carried out, the installer is obliged to provide the client with the following:
Installation, Operation and Maintenance Manual issued by the boiler manufacturer (if such a manual has not been
delivered with the boiler ),
The documents required by applicable regulations,
The installer must teach the client how to handle the device, how to perform regular maintenance and cleaning.
INSTALLATION
The buyer shall be fully responsible for the activities carried out at the installation site.
Prior to installing the boiler , the installer should check if all the safety requirements are met, particularly the following:
The installer is to ensure that the boiler installation is in accordance with local, national and European standards.
The installer is to adhere to all requirements stated in this document.
The installer is to check whether the air supply pipes correspond to the type of the installed boiler .
The electrical connections must not be executed with the use of temporary and/or unsuitable cables.
The installer is to check the grounding of the electrical installation.
The installer must always use personal protective equipment and observe all prescribed precautionary measures.
The installer must always leave enough space for maintenance work.
After completion of the installation, the installer is to measure the emission of flue gases.
PLACING THE BOILER
We advise you to unpack the boiler only when it is put in the place where it is to be installed.
If the surrounding walls or floor are made of materials that are not heat resistant, appropriate protection made of
incombustible insulation material should be used.
In order to protect the floor from inflammable materials, you should put a metal plate 3 to 4 mm thick on the floor
under the boiler that would protrude for 30 cm ahead of the boiler front.
The pellet boiler should be installed in accordance with the diagram which determines the distance from the walls (Figure 2).
Figure 2
All minimum safety distances are indicated on the product data plate, DO NOT use lower values than specified (see
INFORMATION ON CE MARKING).
.If the pellet boiler is installed in a boiler room where there are other air suction devices (other boiler s, various types of
suction fans, etc.), make sure that the volume of air entering the room is satisfactory to guarantee the safe operation of the
boiler .
If the chimney passes through the ceiling, it must be sufficiently insulated with a non-inflammable insulating
material.
Once the boiler is placed, it should be levelled (brought to a horizontal position) with its adjustable legs. It is desirable
that the back of the boiler is raised to be 5-6mm higher than the front part so that the air from the upper part of the boiler may
be discharged completely.
The smoke discharge system MUST NOT be connected to:
The flue pipe used by another heat generator (boiler s, furnaces, fireplaces, etc.),
The air exhaust system (hoods, suction fans, etc.).
It is forbidden to install flue gas flow control units!

3
The Ø100-mm flue pipe from the pellet boiler to the chimney should have the following characteristics:
Total length maximum 5 m (in the case of a larger connection, increase the diameter of the connecting pipe to Ø150
mm),
Each knee of 90˚ reduces the total length of the flue pipe by 1 m, which means that if you have one knee, the total
length can be 4 m, two knees 3 m, etc.
The cap needed for cleaning should be located on each knee;
The connections between the pipes should be sealed.
If there is excessive resistance in the smoke discharge system (numerous knees, inadequate endings, bottlenecks,
etc.), the discharge of flue gases is not guaranteed and the connection pipes and knees should have larger dimensions –Ø150
mm. Similarly, in case the chimney does not allow proper flue gas discharge, there may be an irregularity in operation and,
consequently, the Como Compact 32 Boiler alarm may be activated. It is recommended that the chimney is checked by a
qualified person before installing the Commo Compact 32 Boiler .
The system for discharging smoke from the pellet boiler operates thanks to the underpressure that occurs in the
combustion chamber and barely noticeable pressure in the flue pipe Ø100 mm. Therefore, make sure that the flue pipe is
completely sealed.
It is necessary to carefully analyse the position and condition of the space through which the chimney passes. If the
flue pipe passes through the wall and/or roof, it should be properly insulated in accordance with fire safety regulations.
Make sure that there is sufficient combustion air in the room where the boiler is located. The air supply pipe should
have at least a 110-mm diameter and it should not be longer than 10 m. For each knee of 90˚, the maximum length is reduced
by 1 m. If the pipe is too long, it is necessary to increase the diameter of the air supply pipe.
If a grid is placed on the facade, the air inlet opening should be at least 100 cm2or bigger. The boiler operates at 220-
230 V –50 Hz. Ensure that the electrical cables do not go under the boiler , that they are away from hot surfaces and that they
cannot come in contact with any sharp objects that could damage them. If the boiler is electrically overloaded, this may
significantly shorten the service life of the electrical components of the boiler .
Never turn off the power supply by pulling out the plug while there is still flame in the boiler . This may damage the
boiler seriously and jeopardize the proper operation of the boiler .
AIR SUPPLY
The combustion air must be supplied to the room with the boiler. The room must be continuously aired.
The fresh air opening must be at the bottom of the room and must let in the air.
A) Combustion air supply by pipeline through basements. This connection option preheats the combustion air, which is
useful for good and clean combustion. Installation of pipelines in the basement is simple.
B) Combustion air supply through basements. The combustion air is preheated. The basement space must be separated
from the ventilation system of the house and open to the outside. Avoid high levels of dust and moisture.
V) Combustion air supply from above. Air supply from above can only be performed with tested flue systems.
In this case, you must calculate the dimensioning of the flue!
D) Combustion air supply directly from outside. If the air is supplied directly through the outer wall, the combustion air is
only slightly preheated, which is unfavorable for clean combustion. In this case, there is also a risk of condensation!
NOTE: We do not recommend these versions of the air supply! However, if you use these options, consult a qualified
professional.
The room with the heating appliance must have a sufficient supply of fresh air. If the windows and doors are hermetically
sealed or there are air extracting devices such as a hoods, hair dryers, fans, etc. located in the room with the boiler,
combustion air (fresh air) must be supplied from outside. In any case, this should be discussed with the competent
chimneysweeper before installing the boiler.

Figure 8- Fresh air supply to the room with the boiler
SMOKE DISCHARGE SYSTEM
The smoke discharge must be executed in accordance with the existing standards. Do not connect the flue gas pipe to the
chimney to which the other furnaces have been connected (Figure 3). The flue gas pipe must not end in closed and/or semi-
open spaces, for example, garages, narrow passages, corridors, driveways, etc. After connecting the boiler to the chimney, the
authorized chimney sweep should check if there are any damages in the connection and if the connection has been properly
sealed. If the chimney is not suitable, it must be made in accordance with the requirements stated above (point 3.1).
Figure 3
The flue pipe must be made in compliance with applicable regulations. (Grounding is prescribed by the law.) This
grounding must be independent of the heating device.
When it comes to dimensions and materials, the flue pipe must meet the SRPS 9615-9731, SRPS 10683 - EN1856-1
standards.
Poorly maintained flue pipes or flue pipes made of unsuitable materials (asbestos, galvanized sheet metal, porous materials)
do not comply with the applicable regulations and adversely affect the operation of the boiler .
Flue gases can be discharged via a conventional chimney (see figure below) if the following conditions are met:
Make sure that the chimney is maintained. For proper maintenance and /or renovation of the chimney, contact
the qualified chimney sweep.
Flue gases can be discharged directly into the chimney only if it has a cap for the purposes of inspection and
cleaning and if its cross section is up to 20 x 20 cm, i.e. if its diameter is up to 20 cm.
If the chimney is larger, it is to be fitted with a properly insulated stainless steel pipe (of appropriate diameter).
Make sure that the chimney connection is properly sealed.
Avoid contact with combustible materials (embers) and in any case install fire resistant insulation.
When connecting the pellet boiler to the chimney using connecting elements, it is mandatory to install knees with an
opening for cleaning (Figure 4). If you use knees with an opening for cleaning, this will allow regular cleaning, and you will not
have to disassembly the pipe. The flue gases in the chimney connection are kept under mild pressure, so it is necessary to
check that the cap used for cleaning ash is perfectly sealed and if it remains perfectly sealed after each cleaning. Make sure
that everything is returned in its place and that the seals are in the right position.
Figure 4: Elements for cleaning
The installation of the flue pipes should be performed so that their narrow connecting part is always turned upwards
(Figure 5).
We recommend avoiding using long horizontal extensions to the chimney. If this is necessary, ensure that the pipe is
not counter leaned but that it has an inclination of at least 5% (Figure 6). The horizontal extensions must never be longer than 2
m.
It is not recommendable to connect the boiler directly to the chimney with a horizontal pipe longer than 1 m.

5
Figure 5 Figure 6
The flue pipe must be up to 6 m long with a diameter of 100mm up to the entrance to the chimney. After that, the diameter
of the flue pipe must be increased to 130-150mm. Each knee means a 1 m shorter pipe. Thus, for example, if we have three
curves of 100mm –diameter they change the length of 100-mm-diameter flue pipes for 3m. You can only put 3m of the straight
pipe up to the chimney to reach a maximum of 6m of 100-mm-diameter flue pipes. After that, it must increase, switch to flue
pipes or enter a chimney with a larger diameter, for example 130 –150mm.
Make sure that the curve are not at a sharp angle of 90º. They must be under some radius or made from segments. Sharp
curves increase resistance to passing of smoke through the curve.
- Every knee must have a door that can be opened for cleaning.
- The connections between the connecting pipes must be sealed.
- Use an Ø130mm connector for a longer distance. In this case, the length is up to 8m.
INSULATION AND DIAMETER OF THE OPENINGS ON THE ROOF
Once the position of the boiler has been determined, it is necessary to make a hole i.e. an opening the flue pipe should pass
through. This varies depending on the type of installation, diameter of the flue pipe, and the type of the wall or roof the flue pipe
should pass through. The insulation must be made of insulation material (mineral wool) with nominal density higher than 80
kg/m3.
The ideal underpressure is primarily dependent on the absence of obstacles such as narrowings and /or angular connections.
Knees are recommended to be at 30 °, 45 ° and 90 °. Knees at 90 ° should be three-fold (Figure 7).
In any case, it is necessary to provide an initial vertical flue pipe extension which is at least 1.5 m long. Only in this way can the
appropriate flue gas discharge be guaranteed.

CONNECTION TO ELECTRIC POWER SUPPLY
These boiler s should be connected to the electric power supply. Our boiler s have electrical cables suitable for mild
temperatures. Should the cable be damaged, please consult our authorized maintenance staff. Before you connect the boiler to
the electric power supply, ensure that:
The characteristics of the electrical installations correspond to the data i.e. specification stated on the nameplate
of the boiler .
The smoke discharge system must be grounded in accordance with applicable local regulations. (Grounding is
prescribed by the law).
Under no circumstances may the electrical cable be exposed to a temperature above 80°C
The power cable is part of the equipment that is supplied with the boiler . It is 1.5m long.
Connection to the power supply
The pellet boiler should be connected to the mains.
Place the power cable in the bipolar switch connector located on the back of the boiler (Figure 9a).
Connect the boiler's power cable to the socket (Schuko) with grounding (Figure 9b).
Set the switch to position 1 (Figure 9c). The display of the boiler will light up and LED symbols will appear on it. If the boiler is
not used for a longer period of time, disconnect it from the power supply or turn the switch into the switched off (0) position.
In case of any breakdown or improper operation, switch the boiler off immediately or turn the switch into the switched off
position (0) and contact the authorized maintenance centre.
Figure 9b Figure 9c Figure 9a

7
After installation of the boiler , it is mandatory to measure the emission of flue gases.
MIXING VALVE
- First of all, because of the boiler 's large heat power, and in practice it will happen that the boiler 's reduced thermal power
is used, it is necessary that the hydro installation has a built-in three-way mixing valve to avoid condensation of the boiler .
This would prolong the life span of the boiler .
-For the underfloor heating installation, a mixing valve is required. We recommend special thermostatic floor heating
valves that regulate the water temperature for entry into the floor up to 50ºC. If there is no such a thermostatic mixing valve,
the temperature of the water entering the floor system must be regulated in some other way. This is the duty of the designer
and installer.
-Mixing valve should be 5/4 ".
FIRST FILLING AND IGNITING THE BOILER
FILLING THE INSTALLATION
Before putting on the fire, the entire heating system should be filled with water, well ventilated, and the boiler should be
properly connected to the chimney as explained in the previous sections.
We recommend operating water pressure from 1 to 1.9 bar. It's best to be within the range of 1.2 to 1.6 bar.
The test pressure can be up to 1.9 bar.
NOTE:
The boiler cannot be used without water. It must be connected to the installation where the connected consumers
(radiators) have power of 18kW.
IGNITING THE BOILER FOR THE FIRST TIME
An authorized person is to turn on the boiler for the first time, otherwise the guarantee will cease to be valid.
INSTRUCTIONS FOR THE SAFETY OF PERSONS, ANIMALS AND PROPERTY
We want to draw the installer's attention to some procedures to be respected in order to install the boiler properly. It is necessary
to comply with the required standards, but they are not sufficient. For more precise information, read the remaining part of this
Installation, Operation and Maintenance Manual.
Connect the pellet boiler to the electrical network.
Do not allow children and pets to come near the boiler .
Use only pellets of guaranteed quality and do not use any other types of fuel.
Inform all users on possible risks and hazards, and show them how to handle the pellet boiler .
If the boiler is placed on a wooden floor, it should be insulated in a suitable way.
The boiler functions under underpressure in the combustion chamber and because of that, ensure that the flue pipe is
thermally sealed.
When the boiler is ignited for the first time (at least for one hour), unpleasant paint fumes will be released, and therefore it
is necessary to ventilate the room well.
SAFETY WARNINGS
SAFETY WARNINGS FOR THE MAINTENANCE STAFF
In addition to being obliged to adhere to all safety measures, maintenance staff must:
Always use protective equipment and personal protective equipment as defined in Directive 89/391/EC.
Turn off the electric power supply before they start working.
Always use appropriate tools.
Before starting any operations on the boiler , make sure that the boiler and ash in it are cool, especially before touching
the boiler .
PELLET BOILER IS UNUSABLE IF ONLY A SINGLE SAFETY DEVICE IS FAULTY, IMPROPERLY SET, OR DOES NOT
FUNCTION!
Do not make any modifications for any reason, except those allowed by the manufacturer or an authorized person.
Always use only original spare parts. Never allow the components to completely wear out before you replace them.
Replace worn parts before they completely stop working to prevent damage caused by a sudden breakdown that could
seriously jeopardize the safety of persons and/or your property.
When cleaning the ash, clean both the firebox and the space below it.
SAFETY WARNINGS FOR USERS
The room in which the pellet boiler has been installed or will be installed should be designed in accordance with local,
national and European regulations.
The pellet boiler is a combustion device. During its operation, some parts can be heated to very high temperatures. The C1
class pellet boiler is designed to combust wood pellets (pellets of diameter 6 mm, lengths up to 30 mm and humidity up to 10%),
i.e. fuel C1 (wood pellet) in accordance with EN 14961-2.
WHILE THE BOILER IS OPERATING, CHILDREN MUST NOT COME NEAR IT AND MUST NOT PLAY WITH IT!
During the use of the boiler , it is very important to observe the following safety precautions:

8
DO NOT approach and touch the door of the combustion chamber while the boiler is operating. There is a RISK OF
BURN INJURIES.
DO NOT approach or touch the flue pipe, while the boiler is operating. There is a RISK OF BURN INJURIES.

CHECK-UP AND PARTS TO BE MAINTAINED
CHECK THE BELOW LISTED FACTS SO AS TO ENSURE THAT YOUR PELLET BOILER FUNCTIONS PROPERLY. THESE
PRECAUTIONARY MEASURES GUARANTY BEST PELLET BOILER AND TEMPERATURE PERFORMANCE IN THE SYSTEM:
GENERAL CLEANING AT THE END OF THE HEATING SEASON
Make sure that the pellet boiler and ash are cool. Unplug the power cable of the boiler .
At the end of the heating season, unplug the power cable of the boiler . It is very important to clean
and check the boiler as it is explained in this Manual.
The door seal can be detached after a while even though it is fastened with high temperature resistant adhesives. For
re-fixing, apply a high temperature resistant adhesive (about 1000 ° C) to the back of the seal. This will ensure that the firebox
door is sealed.
CONNECTION OF THE FLUE PIPE TO THE CHIMNEY (at the end of each heating season it should be cleaned).
Make sure that the pellet boiler and ash are cool.
The flue pipe, chimney and chimney cap should be inspected and cleaned once a year. In order to take the
procedure professionally, contact a chimney sweep.
ADDITIONAL MAINTENANCE
Your pellet boiler is a heat source which may use only pellets. Once a year, the maintenance of the boiler should be carried
out by a person authorized by the company “Alfa Plam JSC”.

11
Regular annual maintenance will maintain the proper functioning of the heating device, ensure its greater efficiency,
maintain the warranty and extend the life span of the device itself.
The procedures described in the previous section are advisable at the end of the heating season. The purpose is to check
and ensure the perfect operation of all components.
CHARACTERISTIC BUILT-IN ELEMENTS
THE BOILER IS A COMPLETE PRODUCT AND IT HAS ALL NECESSARY HEATING SYSTEM ELEMENTS BUILT IN, AND THESE
INCLUDE:
CIRCULATION PUMP
It is installed on the return pipe of the boiler , on the boiler itself.
The circulation pump is RS30 / 6.
Another pump is not required except for special heating (floor, with accumulating boiler, etc.).
The pump is reached by removing the so-called the inspection cover which, when you are facing the boiler , is attached
to the sheet metal on the left side of the boiler with screws (Figure 17). Therefore, there must be a greater distance between the
left side of the boiler and the wall. The diagram proposes 700mm.
The circulation pump (Figure 18) has the ability to operate at 2 or 3 speeds, depending on the resistance in the heating
system. The second speed is factory set. If necessary, you can change the speed.
If a high efficiency pump (for the needs of the EU) is installed, it adjusts the speed itself depending on the resistance in
the system.
The electronic parameters are set to activate the pump at water temperature of 50 ° C, and switches off at 47 ° C.
The pump shaft must be in a horizontal position. Therefore, be careful when connecting to a heating installation so that
it does not rotate.
When the pump does not operate for a long period of time, there is a risk that the pump shaft jams and cannot start at
the set water temperature (50 °C.). In this case, reach the pump and use the screwdriver to remove the short screw from
the pump head (a little water will flow), and then use the screwdriver to get the pump shaft located under the removed
screw working by turning the pump shaft with the screwdriver left-to-right.
Figure 17 Figure 18
EXPANSION TANK
By removing the inspection cover (Figure 17), you can reach the expansion tank (Figure 19).
The volume of the expansion tank is 18 litres.
The factory set pressure is 1 bar.
It has function to stabilize the pressure in the heating installation.
It meets the boiler heat capacity of 37.5KW and another tank is not required up to this heat power. It can be used, but it
does not have to.
For larger systems, larger expansion tanks are needed for larger water volumes.
The expansion tank has a pressure regulating valve in it.
FILL AND DRAIN COCK
By removing the inspection cover (Figure 17), the fill and drain cock is reached (Figure 20).
As the name says, it serves to fill and drain the installation.
It is located at the lowest point of the system.
The inlet connector is R1 / 2 "and the outlet connector has hose extension. It is ball shaped.
ELECTRONIC SYSTEM
By simply removing the inspection cover (Figure 17), you can reach the electronic system (Figure 21).
The electronic system is "TIEME" from Italy.
The electrical connection diagram is given in this Manual.
All cables, from all consumers, from safety mechanical thermostats, electronic probes, pressure switches, etc. are
connected to the electronic system.

NON-RETURN VALVE, AUTOMATIC AIR VENT VALVE, SAFETY VALVE AND WATER
PRESSURE SENSOR
They can be reached by removing the right side, if you are facing the front side of the boiler . It is not shown in a figure, but
the boiler is shown where the right side is shown in the foreground (Figure 22). All these elements are built in the boiler at the
factory.
7.4.5.1 NON-RETURN VALVE
Non-return valve R5 /4" is installed on the boiler 's pressure line in the factory (Figure 23).
It does not allow cold water to return from the system when the pump is stopped, which prevents condensation of the
boiler .
If there are more than one pump in the installation system, it is necessary to install more non-return valves. A non-
return valve is placed behind each pump.
Make sure that the non-return valve is easy to open (use your finger) so that the pump force can open it.
The non-return valve prevents water in the boiler from cooling and thus prevents creating condensation in the boiler
and smoke pipes. Condensation can occur until 2 - 3 fuel tanks have been used.
Condensation in the boiler when the boiler is started for the first time is normal.
7.4.5.2 AUTOMATIC AIR VENT VALVE
Automatic air vent valve is positioned on the pressure line, under the lid at the highest point of the boiler .
Its purpose is to exhaust air from the boiler .
To get to the valve, you must take the right side off (when facing the boiler ).
Valve safety cap should be loose, not too tight, so that the air could freely leave.
7.4.5.3 SAFETY VALVE
The safety valve is with R1 / 2 "connector, with an outlet on the back side, above the non-return valve.
The safety valve is positioned under the furnace lid on the pressure line. Inlet connector is R1/2". Valve opens at water
pressure of 2.5 bars.
To get to the valve, you must take the right lateral side off (when facing the boiler ).
The safety valve outlet whose white alpex pipe Ø16mm is above the pressure line must be discharged into the sewer.
7.4.5.4 WATER PRESSURE SENSOR
The water pressure sensor does not allow the boiler to operate at low and high pressures. It is factory set to a minimum
operating pressure of 0.2 bar and a maximum of 2 bar.
If the pressure drops below 0.2 bar or increases over 2 bar, the boiler is switched off.
When facing the boiler , you can get to it by removing the right side.
Figure 22 Figure 23 Figure 24
MECHANICAL SAFEY DEVICES –THERMOSTATS
In addition to other safety devices, the boiler is protected against overheating with two mechanical thermostats. Their
outlets with black protective caps are shown in Figure 24.
The upper thermostat ensures that the boiler does not get overheated.
The lower thermostat ensures that screw feeder does not get overheated.
If the temperatures to which the thermostats are set up are reached, the boiler switches off.
It is necessary to wait for the boiler to cool down and then reset the thermostat that got activated.

13
First unscrew the black thermostat protective cap and then push the tube located in the middle of the thermostat until
a low metal sound is heard.
The boiler can be switched on again only after that.
FRESH AIR INTAKE, SMOKE DISCHARGE SYSTEM, RETURN AND PRESSURE LINE
The aforementioned parts may be seen at the rear side of the boiler .
The supply of fresh air is through the pipe shown in Figure 25.
A sufficient amount of fresh air is required for total combustion.
A fresh air supply must be provided in the room where the boiler is located as shown in Figure 8.
The flue gas discharge from the boiler is shown in Figure 26. The diameter of the flue pipes is Ø100mm.
Observe the instructions for the flue gas discharge described in section 3.2. (in this Manual).
The pressure line, Figure 23, and the return line, Figure 27, are 5/4 " and end in hollender parts that are protected by
plastic protectors. Other parts of the hollender with rubber seals are packed, and delivered with the boiler .

IMPORTANT SAFETY INFORMATION
You have bought a top quality product.
The supplier will be always available to provide any further information you may need. The proper installation of the boiler
in accordance with the instructions given in this Manual is very important for preventing breakdowns, fire hazards or fire risks
The boiler pellet operates with underpressure in the combustion chamber, therefore, you must ensure that connections to
the chimney are sealed and leak-proof.
In the event of fire in the chimney, evacuate all people and pets from the room. Turn the power supply off immediately using the
main switch or by unplugging the power cable (only if you do
not expose yourself to a risk), and immediately call firemen.
In order to preserve safety and proper functioning of the pellet boiler , do not use chopped wood.
Do not use the boiler for burning garbage.
THE PELLET QUALITY IS VERY IMPORTANT
The pellet quality is very important!
The boiler is designed to use pellets. Since various types and dimensions of pellets appear on the market, it is important to
choose pellets that do not contain impurities, and which are compact and do not produce dust. Uses pellet which meets the
European standard, minimum EN plus A2.
Consult your supplier about the type of pellet, whose size must be 3,15-40 mm and cross section is 6 mm. The proper
functioning of the boiler depends on the type and quality of the pellet.
Under no circumstances shall the manufacturer be responsible for the poor operation of the boiler due to the use of poor quality
pellets.
If sawdust or small –decomposed pellets are put into the funnel-shaped part of the boiler i.e. the fuel tank, these may block
the pellet feeding. Such pellets may obstruct the operation of the gear motor driving the pellet feeding mechanism, or they may
damage the gear motor. If you see any such small, decomposed pellets at the bottom of the pellet tank or at the bottom of the
screw conveyor when the tank is empty, vacuum them with the vacuum cleaner by inserting the vacuum cleaner hose through
the openings of the pellet grate. Or even better, every one or one and a half months vacuum clean the tank bottom in the above
described way when the tank has a little quantity of pellet.
PELLET STORAGE
Pellets must be stored in a dry place which is not too cold. Cold and wet pellets (with a temperature of around 5 °C) decrease
the thermal power of the fuel and require additional boiler cleaning.
People with damaged spine and pregnant women should avoid raising pellet bags.
The manufacturer denies any responsibility for any damages or poor operation of the boiler due to the use of poor quality
pellets.

14
The pellet must conform to DIN 51731, DIN plus, Ö-Norm M-7135 or other comparable European standards.
THE PELLET MUST NOT BE KEPT NEAR THE BOILER . Keep them at least half a metre away from the boiler .
When handling pellets, make sure that pellets do not spill.
If you pour the sawdust into the pellet tank, you may block the pellet loading system.
BOILER CONTROL SYSTEM
The boiler has an advanced control system that allows safe, efficient and reliable operation control and maximum functional
utilization of the boiler .
It is characterized by:
Easy to set up and use,
Simple and direct user functions,
Reliable and flexible functional software specially developed for pellet boiler s,
Advanced features available for installers to adapt different configurations and installations.
