IMPORTANT WARNINGS!
IMPORTANT: The connection of the device to the power supply installation must be compulsorily performed by qualified
and authorized persons in accordance with the valid legal regulations.
This device has not been foreseen for application by persons (including children) with reduced physical, motor and mental
abilities or persons with limited knowledge and experiences without the presence of persons responsible for their safety i.e.
care.
Children must not play with these types of devices.
DUAL COMBUSTION SYSTEM
The flame obtained by the normal combustion of wood in the boiler emits the same quantity of carbon dioxide (CO2) that
would be released as a result of the natural decomposition of wood.
The quantity of carbon dioxide (CO2) obtained by the combustion or decomposition of plant mass corresponds to the
quantity of carbon dioxide (CO2) that plant mass is capable of obtaining from its surroundings and transforming it into oxygen
for air and carbon of the plant during its whole life.
The use of non-renewable fossil fuels (coal, oil, gas), contrary to what happens with wood, releases into the atmosphere
enormous quantities of carbon dioxide (CO2) accumulated for millions of years, thus causing the greenhouse effect. The use
of wood as fuel is therefore perfectly balanced with the environment because wood as renewable fuel is in ecological harmony
with nature.
These goals are completely accomplished through the principle of clean combustion and this is why the designs of the
ALFA PLAM products are based on this principle.
What does clean combustion mean and how does it take place?
The control and adjustment of primary air and the introduction of secondary air generate, i.e. cause secondary combustion
or the so-called post-combustion that produces the secondary flame which by its nature is brighter and stronger than the
main or primary flame. The addition of new oxygen (through the introduced air) enables the additional combustion of gases
that were not completely combusted. This significantly increases the thermal effect and decreases the harmful emissions of
carbon monoxide (CO) because the incomplete combustion is reduced to a minimum. These are the basic characteristics of
the boilers and other products of ALFA PLAM.
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.

1. THE PURPOSE OF THIS MANUAL
The purpose of this Manual is to enable the user to take all necessary measures and prepare all necessary equipment and
materials in order to ensure the safe and proper exploitation i.e. use of the boiler.
1.1. UPDATING
This Manual presents the state-of-the-art at the moment the boiler is placed on the market. Therefore, ALFA PLAM does
not take into account the boilers already on the market with appropriate technical documents, and considers them faulty or
inadequate after any modifications, adaptations or application of new technologies to newly launched machines.
The contents of this Manual must be read and study very carefully. You should strictly adhere to all the instructions given
in this Manual. All the information included in this booklet is necessary for the installation, use and maintenance of your boiler.
Therefore, this Manual must be carefully kept because of its instructions that may be necessary if any problem or
ambiguity arises.
If the boiler is handed over or resold to another person, the new owner must also be given this Manual.
If you lose this booklet, you can ask the manufacturer for a new one.
2. THE RESPONS IBILITY OF THE MANUFACTURER

Upon publishing this Manual, ALFA PLAM will not accept any civil or legal responsibility, either direct on indirect, due to:
− Accidents occurred due to the non-observance of the standards and specifications stated in this
Manual,
− Accidents occurred due to the improper operation or use of the boiler by the user,
− Accidents occurred due to any modifications and repairs not approved by ALFA PLAM,
− Poor maintenance,
− Unpredictable events,
− Accidents occurred due to the use of spare parts that are not original spare parts or that are not
intended for these models of the boiler.
The installer of the boiler shall take the full responsibility for the installation.
2.1. THE BASIC CHARACTERISTICS OF THE USER

The boiler user must be an adult and responsible person.
Make sure that children do not approach the boiler while in operation, with the intention of playing.
Children must not approach the boiler while in operation with the intention of playing. This appliance can be used by
children aged 8 and older and persons with reduced physical, sensory or mental abilities, if they are supervised by an adult
who is familiar with the instructions for use. Boiler cleaning and maintenance cannot be performed by children without the
supervision of an adult.
2.2. THE TRANSPORTATION AND USE OF THE BOILER – HANDLING

During the use of the boiler care should be taken that the boiler is not leaned forward because the centre of gravity of the
boiler is oriented forward.
While moving the boiler, which must be carried out absolutely safely, ensure that the forklift truck has a carrying capacity
that is higher than the weight of the boiler it should lift. Avoid twitches and abrupt movements.
ALL THE PACKAGING MATERIAL SHOULD BE REMOVED AWAY FROM THE REACH OF CHILDREN AS THE MATERIALS
CONTAINED IN THE PACKAGING MAY CAUSE SUFFOCATION. THESE INCLUDE PLASTIC BAGS, FILMS, STYROFOAM, ETC.
2.3. THE RESPONSIBILITY OF THE INSTALLER

The responsibility of the installer is to perform all the checkups of the flue piping, air intake/supply, as well as all the
solutions required for the installation (incorporation) of your boiler.
The responsibility of the installer is to ensure that the boiler is in compliance with local regulations applicable in the place
where the boiler is installed (incorporated).
The use of the boiler must be in accordance with the instructions given in this Manual for use and maintenance, as well as
with all the safety standards prescribed by local legal regulations applicable in the place where the boiler is installed
(incorporated).
The installer must verify (confirm):
− The type of the boiler that is being installed,
− Whether the room in which the boiler is being installed is appropriate, which is expressed as the minimum size of
the room required for the installation as prescribed by the boiler manufacturer,
− Instructions of the heat generator manufacturer, related to the requirements of the smoke discharge system
(smoke discharge ducts and pipes),
− The internal cross section of the chimney, material the chimney is made of, cross-sectional uniformity, whether
there are any obstacles and barriers in the chimney,
− The height and vertical extension of the chimney,
− The height above the sea level at the place of installation/incorporation,
− The existence and suitability of a wind resistant protective cover of the chimney,
− The possibility of providing the external air intake and the size of required openings,
− The possibility of the simultaneous use of the boiler which is to be installed, together with the other equipment
already existing in that place.
If the results of all the checkups are positive, then the installer may proceed with the incorporation/installation of the
boiler. The instructions provided by the boiler manufacturer, as well as the fire prevention standards and safety standards
must also be observed.
1
When the installation is completed, the system must be put into a trial operation for at least 30 minutes in order to check
up all the packing and seals of the system.
When the incorporation and significant details are completed, the installer is obliged to provide the client with the
following:
− The Use and Maintenance Manual issued by the boiler manufacturer (if such a manual has not been delivered
with the boiler),
− The documents required for the compliance with existing standards.
3. THE INSTALLATION – INCORPORATION OF THE BOILER

The user shall be fully responsible for the works executed at the incorporation site.
Before putting the boiler into operation, the installer must meet all legal safety standards, in particular:
− Ensure that the boiler installation is in accordance with local, national and European regulations,
− That it fulfils the requirements stated in this document,
− That the installation of the flue piping and air intake corresponds to the type of the installed boiler,
− That the electric connections must not be executed with the use of temporary and/or non-insulated electric cables,
− Check the efficiency of the electrical system grounding,
− Always use the personal protective equipment and all the protective means prescribed by applicable local
regulations,
− Always ensure sufficient servicing space required for any maintenance and repairs of the boiler.
3.1. PLACING THE BOILER

We advise you to unpack the boiler only when it is put in the place where it is to be installed.
The boiler stands on plastic legs with cast-in screws M10 (4 pieces) screwed into the base of the boiler. Nuts M10mm are
screwed onto the screws up to the plastic part. The legs are also maximally screwed, up to the base of the boiler. When you
unpack the boiler and bring it to the spot on which it is to be installed, unscrew all the legs to obtain the total height from the
floor to the boiler base i.e. to ensure that the legs are protruded from the boiler base for around 25mm. When you finish
levelling the boiler which should stand horizontally, tighten the nuts while holding the plastic part of the leg with your hand.
Tighten the nuts using spanner 17 so that they reach the boiler base. The height of around 25mm from the floor to the boiler
base is needed for air circulation and better boiler cooling. In this way, you will protect the boiler against overheating and
extend its service life.
If the surrounding walls and/or floor are made of materials that are not heat resistant, appropriate protection should be
used consisting of incombustible insulation material.
Always ensure a safe distance (around 35/40 cm) between the boiler and your furniture, home appliances, etc. In order to
protect the floor, if it is made of combustible material, we suggest that you put on the floor, under the boiler, a metal plate with
a thickness of 3 to 4 mm that would protrude for 30 cm ahead of the boiler front.
All minimum safety distances are indicated on the product data plate, DO NOT use lower values than specified (see
INFORMATION ON CE MARKING).
The boiler must be placed at a distance of at least 25 cm from the surrounding walls. Always leave at least 15 cm between
the back of the boiler and the wall in order to ensure the proper circulation of air, i.e. to allow air to properly flow through this
space.
If the boiler is to be placed in a kitchen with a ventilation grid, or if it is to be placed in rooms with solid fuel heat generators
(such as wood burning boilers), always ensure that the quantity of the inlet air (into the kitchen or room) is sufficient to provide
the safe operation of the boiler.
If the smoke discharge channel should pass through the ceiling, the ceiling should have proper thermal insulation made of
incombustible insulating material. Once the boiler is placed, it should be levelled with the use of the adjustable legs.
DANGER
The smoke discharge fittings MUST NOT be connected to:
− The flue pipe used by another heat generator (water heaters, boilers, fireplaces, kitchen boilers, etc.),
− To the air exhaust system (grids, vents, etc.), even if the system is inserted in the pipe discharge.
DANGER
It is prohibited to install air circulation (draught) shut-off valves (flaps, valves that may prevent air circulation i.e. that may
prevent draught).
CAUTION
If the smoke discharge path produces poor draught i.e. poor air circulation (if the path has numerous bends, inappropriate
smoke discharge end, narrowing, etc.), the smoke discharge can be bad, i.e. inappropriate.
The smoke discharge system functions on the basis of the negative pressure and mild pressure of the flue pipe. It is very
important that the smoke discharge system is sealed. This requires the application of a pipe smooth inside. When the flue pipe
is to be placed through the walls and roof, the plan and structure of the room should be thoroughly analysed and studied first,
so that the pipe may be placed properly in accordance with the fire prevention standards.
2
First, it should be ensured that there is sufficient combustion air in the room where the boiler is located. Occasional
inspection is recommended to ensure that combustion air is properly supplied to the biofuel combustion chamber. The boiler
operates on 230 V – 50 Hz. Ensure that the electric cable is not entangled under the boiler, that it is away from hot places and
that it cannot come in contact with any sharp edge that could cut it. If the boiler is electrically overloaded, this may shorten the
service life of the electronic parts of the boiler.
Never turn off power supply by pulling out the plug while flames are still burning in the boiler. This may jeopardize the
proper operation of the boiler.
3.2. 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.
Fresh air supply to the room with the boiler
3.3. THE SMOKE DISCHARGE SYSTEM

The smoke discharge must be executed in accordance with the existing standards. The flue pipe should be thoroughly
sealed. See Figures 1 to 7.
For smoke discharge, classic brick chimneys can be used, or chimneys may be made of pipes that must be thoroughly
insulated (double wall) and sealed in order to prevent condensation in them.
The discharge pipe must not be connected with other systems of any type, such as the systems for discharging smoke
from the combustion chamber, exhaust grid or air distribution systems, etc. Furthermore, the flue pipe must not be located in
closed or semi-closed rooms such as garages, narrow corridors, under closed huts or any other place where smoke may
appear. When the boiler is to be connected to the flue piping, a professional chimney sweep should be called to verify that
there are no even tiniest cracks or fissures in the chimney. If the smoke discharge chimney has any cracks, the flue pipe must
be wrapped in new material in order to ensure proper functioning.
For this purpose, rigid pipes made of non-ferrous steel (with a minimum thickness of 1.5 mm) can be used, or pipes made
of stainless steel (with a minimum thickness of 0.5 mm).
The smoke discharge system (chimney) made of metal pipes must be grounded in accordance with applicable standards
and legal regulations. Grounding is prescribed by the law.
This grounding connection must be independent of the boiler grounding.
The flue pipe must be made in compliance with the standards regarding the dimensions and materials used for its
construction (Figure 1).
A) Wind resistant chimney top
B) Maximum cross section of 15 x 15 cm or a diameter of 15 cm, maximum height of 4-5 m.
C) Seal
3
D) Inspection – control opening.
Flue pipes in bad condition or made of inappropriate material (asbestos cement, galvanized sheet metal, etc. with coarse
and rough or porous surfaces) are illegitimate and they jeopardize and hamper the proper operation of the boiler.
Smoke can be discharged through a classic flue pipe (see the figures below) provided that the following regulations are
met:
− Check the maintenance condition of the flue pipe or the chimney. If the discharge flue pipe is old, it should be
replaced by a new one. If the chimney is damaged, it should be repaired or refurbished by inserting a steel pipe
properly insulated with mineral wool.
Figure 1
Figure 2
− Smoke is discharged directly into the flue pipe (chimney) only if its cross section is up to 15 x 15 cm or if its diameter is
up to 15 cm and if it has a cover for the purposes of inspection and cleaning.
− If the cross section of the chimney is larger than 15x15cm or its diameter is larger than 15cm, the possible control of
increased draught (decreasing) in the chimney can be performed in three ways:
1. If there is an opening for the purpose of cleaning at the bottom of the chimney, it should be partially opened.
2. A steel pipe with a diameter of 10 cm should be inserted into the chimney if you have elements for such a refurbishment
of the chimney.
3. By the regulation of certain parameters in the boiler. This regulation can be performed only by an authorized service
centre of Alfa plam.
− Ensure that the connection for the house chimney is properly sealed.
− Avoid any contact with easily combustible material (such as wooden beams), and in any case these should be insulated
with fire resistant material (see Figure 2).
A) Mineral wool
B) Steel pipes
C) Partition plate.
The boiler is designed for the connection to the chimney with flue pipes whose diameter is 80mm. If the standard chimney
is not used but a new one is being constructed or the existing chimney is being refurbished, use insulated stainless steel pipes
(double wall) of the diameter of the flue pipe in accordance with Table 1. The use of flexible pipes is not allowed.
SYSTEM TYPE DIAMETER mm SYSTEM ASSESMENT

Pipe shorter than 5 m 100 acceptable
Pipe longer than 5 m 120 obligatory
Installation at places where the elevation above the sea level is 120 recommendable
higher than 1,200 meters
Table 1
When you use a connecting pipe between the boiler and the discharge flue pipe, you must also use a “T” coupling (as it is
shown in Figures 5 and 6), with the cover for the purpose of cleaning (plug) next to the boiler. The application of this “T”
coupling must enable the collection of ashes generated inside the pipe and cleaning of the discharge flue pipe from time to
time without removing the pipe. The smoke is under mild pressure. Because of this, it is necessary to check if the opening i.e.
the cover (plug) for cleaning the smoke discharge system is perfectly sealed and if it remains perfectly sealed after each
cleaning. Ensure that the assembly is carried out in the same order and check the condition of the seal.
The installation of the flue pipes should be performed in accordance with Figure 7.
It is strictly recommended to avoid using horizontal extensions or elongations and if this is necessary, ensure that the pipe
is not counter leaned but that it has an inclination of at least 5%. The horizontal extensions must never be longer than 3 m.
A maximum length of 5m is allowed for flue pipes with a diameter of 80 mm up to the entrance to the chimney. Each knee
is calculated as 1 extra meter of length. So, for example, if we have three curves with a diameter of 80 mm, they shall modify by
3 m. the length of the flue pipes with a diameter 80 mm. That means that can you install only 2 more meters of straight pipes
up to the entrance of the chimney to achieve the maximum 5m length of flue pipes with a diameter of 80mm. After that, you
need to use higher values, i.e. you should switch to flue pipes or use a chimney with a larger cross-section, for example 100 -
120 mm.
Figure 3 on the left shows how the end (top) of the chimney should look like when there are two chimneys one next to the
other, and Figure 3 shows how the end should not be executed.

3.4. THE INSULATION and DIAMETER OF THE OPENING S (Holes) ON THE

ROOF (or on the Wall)
Once the position of the boiler is 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 (see Table 1) and the type of the wall or
roof the flue pipe should pass through. See Table 2. The insulation must be made of mineral wool with nominal density higher

It is recommended that knee-shaped flue pipes are three-fold to minimise the resistance of smoke passage. It is also
recommended that one of the used knees and positioned in a suitable place has an opening for easier and more efficient
cleaning of flue pipes. See image 7a.

obstacles such as narrowing or angles. Any shifts of the axis must have one path inclined with a maximum angle of 45
degrees from the vertical, and the best solution is 30 degrees. These shifts should be best performed near the wind resistant
top of the chimney.
In accordance with regulations (the wind resistant top of the chimney, distances and boiler placing), the distances shown
in Table 3 must be met:
Roof Distance between the roof ridge cover and the Minimum height of the chimney measured at the
inclination chimney upper opening (at the chimney outlet)
α Distance in meters Height in meters
15
0 Less than1.85 m 0.50 above the roof ridge cover
More than 1.85 m 1.00 meter from roof pitch
30
0 Less than 1.50 m 0.50 above the roof ridge cover
More than 1.50 m 1.30 meters from the roof pitch
45
More than1.30 m 2.00 meters from the roof pitch
60
More than 1.20 m 2.60 meters from the roof pitch
Table 3

However, it is obligatory to provide an initial vertical extension (elongation) of 1.5 m (minimum) in order to provide a
proper smoke discharge.
3.5. THE INTAKE OF COMBUSTION AIR (Figure 8)

The air necessary for combustion, taken from the surroundings, must be regenerated through a ventilation grid located on
the wall of the room and turned outwards. This will provide a better combustion and a lower consumption of biofuel pellets. It
is not recommendable that external air is sucked directly through the pipe, because it would decrease the efficiency i.e.
performance of combustion. On its external side, the ventilation opening must be equipped with a ventilation grid as protection
against rain, wind and insects.
This opening must be made on the external wall of the room in which the boiler is located.
The intake, i.e. supply of combustion air from garages, warehouses for combustible materials or fire hazard rooms, is
prohibited.
The hole, i.e. opening for external input combustion air must not be connected with the use of pipes.
If the room also has any other heating equipment, the intake of combustion air must provide the amount of air necessary
for the proper operation of all the devices.
Figure 8.Minimum distances for the installation of the ventilation grid
For the proper and safe installation of the ventilation grid, see the data in Table 4. These are minimum distances form any
air space or smoke discharge. This value can change the configuration of air pressure. These distances should correspond to
the sequence in order to ensure, for example, that an open window intakes external air, taking it away from the boiler itself.
The ventilation grid must be installed at least

1m under the door, window, flue pipe, air chambers, etc.
1m horizontally from
0.3 m above
2m away from smoke outlet
Table 4: Minimum distances for the intakes of combustion air
3.6. CONNECTION TO THE ELECTRIC POWER SUPPLY

These boilers should be connected to the electric power supply. Our boilers have electric cables suitable for medium
temperatures. If the cable should be replaced (e.g. because it is damaged), please consult our authorized technical personnel,
our experts. Before you connect the boiler to the electric power supply, ensure that:
− The characteristics of the electric system correspond to the data i.e. specification stated on the nameplate of the
boiler.
The smoke discharge system, if it is metal, must have an operational grounding connection in accordance with
applicable standards and legal regulations. Grounding is prescribed by the law.
0
− The electric cable must never reach a temperature which is by 80 C higher than the ambient temperature. If you
want to obtain a direct connection to voltage, you should install a bipolar switch with a minimum clearance of 3
mm between the contacts, with the dimensions for electric load shown in the nameplate, and in accordance with
applicable standards. Yellow-green grounding cables must not be switched off by the switch. When the boiler is
installed at its place, the bipolar switch or the socket must be easily accessible.
− If the boiler will not be used for a longer period, switch it off from the power supply or turn the switch into a
switched off (0) position. In the 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 service centre.
4. IMPORTANT INSTRUCTIONS
THESE ARE IMPORTANT OBLIGATORY INSTRUCTIONS FOR THE SAFETY OF PEOPLE, ANIMALS AND PROPERTY.
8
We would like to inform the boiler installer on some general instructions that he must adhere to in order to install the boiler
properly. These standards are required, but not fully. For further and more precise information, read the remaining part of this
Manual.
− Connect the boiler to a grounded socket. Figure 9
− Put the switch on the back of the boiler in position 1. Figure 10
− Do not allow children and pets to come near the boiler.
− Use only biofuel pellets, and not any other types of fuel.
− Inform all the users on possible risks and dangers and teach them how to handle the device.
− If the boiler is installed on a wooden floor, it is recommendable to insulate its stand.
The boiler functions with a negative pressure combustion chamber. Because of that, ensure that the flue pipe is thermally
sealed i.e. insulated.
When the boiler is lit for the first time, a smaller quantity of paint (not harmful to health) covering the boiler will evaporate
because of the painting process stabilization. Ventilate the room in order to remove these vapours from it. Ventilate the room
in order to remove vapours.
Figure 9 Figure 10
5. WARNING OF THE SAFETY MEASURES FOR THE MAINTENANCE

STAFF
Besides being obliged to adhere to all safety measures, maintenance workers must:
− Always use security devices and personal protective equipment.
− Turn off the electric power supply before they start working.
− Always use adequate tools.
− Ensure that the boiler and ash are completely cool before starting any operations on the boiler.
Especially, take care that the handles are cool before you touch them.
− NEVER START UP THE BOILER even if only one of the security devices is faulty, improperly set or does not
function.
− Do not make any modifications for whatever reason except those allowed and explained by the manufacturer.
− Always use original spare parts. Never allow the components to completely wear out before you replace them.
Replacing a worn out part i.e. component of the boiler before it breaks down contributes to the prevention of
injuries caused by an accident due to a sudden breakdown i.e. failure of the component that may cause serious
human injuries and damages to the property around the boiler.
− Clean the firebox before lighting the boiler.
− Check whether any condensation has occurred. If any condensation occurs, this indicates that there is some
water from smoke cooling. We recommend you to find possible causes in order to establish a normal and proper
work of the boiler.
5.1. WARNING OF THE SAFETY MEASURE S FOR THE USER

The place where the boiler is to be put, called the installation place, must be prepared in accordance with local, national
and European regulations.
The boiler is a ’’heating machine’’ and during its operation, its outer surfaces are very hot i.e. they have extremely high
temperatures, or they are rather hot.
This boiler is designed to combust fuel made of pressed wood mass (pellets with a diameter of 6 mm, length of about 40
mm and maximum moisture of 8-9%).
Because of this, during the use of the boiler it is very important to observe the following warnings:
− Do not approach and touch the glass on the door, there is a RISK OF BURN INJURIES
− Do not approach and touch the flue pipe, there is a RISK OF BURN INJURIES
− Do not perform any kind of cleaning
− Do not open the door as the boiler functions properly only when it is sealed
− Do not remove ashes when the boiler is in the operational mode
− Children and pets must be away from the boiler
− ADHERE TO ALL THE REGULATIONS STATED IN THIS DOCUMENT – MANUAL.
In addition, for the proper use of biofuel pellets:
9
− Only use fuel which is in accordance with the manufacturer’s instructions,
− Always adhere to the boiler maintenance plan,
− Clean the boiler every day (only when the boiler and ashes are cold),
− Do not use the boiler if there are any failures or abnormalities, or in the case of unusual noise and/or suspected
breakdowns,
− Do not throw or pour water on the boiler, even in fire fighting,
− Do not turn off the boiler by pulling the plug out. Use the off button on the panel,
− The boiler should not be inclined as IT MAY BECOME UNSTABLE,
− Do not use the boiler as a support or holder. Never leave the tank fuel cover opened,
− Do not touch the painted parts of the boiler while it is in operation,
Do not use wood or coal as fuel, but only fuel pellet with the following characteristics: diameter of 6 mm, maximum length
40 mm, maximum moisture 8-9%,
− Do not use the boiler for burning garbage,
− Always perform all the operations with maximum safety measures.
6. STANDARDS FOR SAFE LIGHTING AND CLEANING THE BOILER

− Never use gasoline, petroleum or any other combustible liquid for lighting the boiler. Keep these kinds of liquid
away from the boiler while it is in operation,
− Never light the boiler if the glass is damaged. Never hit the glass or door as you may damage them,
− While the boiler is in operation, do not open the door in order to clean the glass. The glass can be cleaned only
when the boiler is cool, using a cotton cloth or paper towels (cloths) and a glass cleaning agent,
− Ensure that the boiler is fixed well in order to prevent any movement,
− Ensure that the box for ashes is inserted and that it is completely closed, so that the door is properly leaned
against the inner box,
− Ensure that the boiler door is tightly closed while the boiler is in operation,
− Remove ashes with a vacuum cleaner only when the boiler is completely cool,
− Never clean the boiler surfaces with any abrasive cleaning agents.
6.1. ROUTINE CLEANING and MAINTENANCE PERFORMED BY THE USER

OF THE BOILER
The use of a drum-shaped vacuum cleaner can facilitate the boiler cleaning. The vacuum cleaner must have a filter which
stops the vacuumed dust to go back into the room where the boiler is located.
Before you start any routine maintenance, including cleaning, you should take the following safety measures:
− Shut off power to the boiler before you start any works,
− Before you start any works, ensure that the boiler and ash are cool,
− Vacuum the ash from the combustion chamber every day,
− Carefully clean the firebox with the vacuum cleaner every day (after every use and when the boiler is cool),
Always ensure that the boiler and ash are completely cool.
-FIREBOX (box-shaped) is a place where wood mass pellets burn. See Figure 11It is recommended that the firebox should
be cleaned with a vacuum cleaner after each use (when the boiler is cool). After every third use, it is recommended that the
firebox should be taken out for ensuring that there is no excessive ash accumulated at the bottom of the firebox. Then place
the firebox back in its place, making it stable, to ensure the safe operation of the boiler.
If you have any doubts, please do not hesitate to call the authorized service centre for further information and clarification,
as the manufacturer does not have any insight into the installation of the boiler and does not offer any warranty for the
incorporation of the boiler and its maintenance.
The manufacturer shall not be liable for any damages caused by third parties.
2. For the best performance of the

boiler, all the holes must be free of 1. Hole for entering a heating
ash
Figure 11 element to ignite the fuel
- ASHTRAY (if it is full, you should clean it with a vacuum cleaner or empty it):
Make sure that the boiler and the ash are cold
The upper ashtray must be cleaned every day or every other day, with a vacuum cleaner or simply by disposal of the ash.
Ash-bin may be opened in two ways:
The first way is by turning or pulling the specially made handrails on the handrail of the ash-bin towards oneself while
holding them with both hands. See image 12.
10
The second way is with a special key whose bent end should be inserted into the slot on the handrail and then pulled
towards oneself. See image 13.
Figure 12 Figure 13
In this manner all dirt that stays inside during the combustion of pellets will be removed. Then the ash box must be
properly returned to its position. Do not ever put pellets that have not burnt down in the ashtray or ash box.
The lower ash box must be cleaned once in fifteen – twenty days, with a vacuum cleaner or simply by disposal of the ash.
During this, two butterfly nuts should be loosened. In this manner all dirt that remains inside during the combustion of pellets,
will be removed.
At the same time, clean with a vacuum cleaner the flue extension of the chamber through the opening at the front side of
the boiler for the lower ashtray.
Then the lower ashtray must be properly returned to its position.
- FLUE PIPE IN THE BOILER (SIDEARM HEAT EXCHANGER )
It should be cleaned by manual shaking with a special rod at each consumed 40-50kg of pellets (one full pellet tank). The
same rod can be inserted in the openings of the crank – the pins where the springs for cleanings are connected and shake
them after lifting them and lowering them for few times, as shown in figure 14.
Figure 14 Figure 15
-LOWER SMOKE CHAMBER

It should be cleaned manually at each consumed 90-100 kg of pellets (two full tanks). Raise the cover of the pellet tank. In
the tank, in the front upper part, under the cover, there is a button for the mechanism for cleaning the chamber. By pulling the
button for the mechanism few times forward-backward, you will clean the chamber. Don't become worried if the mechanism is
a bit difficult to move or if it scratches. In this manner it performs the cleaning of the chamber.
- FLUE PIPES IN THE BOILER, (UPPER HEAT EXCHANGER IN THE BOILER)
It has to be cleaned after a consumption of 200 – 250kg of pellets. Open the door of the boiler and clean the inside of the
heat exchanger's tube in the boiler located above the firebox with the special steel brush which came with the boiler by
sweeping the brush lengthwise (vertically) up and down several times through each tube. There is a total of five tubes. Use
protective gloves when cleaning because of soot. Clean when the boiler is cold. See image 16.
Figure 16
Perform cleaning when the boiler is cold. After cleaning the button should always be returned completely inwards so that
only the button would be visible, and not the bar from the cleaning mechanism. See figure 16.
Use a vacuum cleaner to vacuum the ashes at the door opening, behind the glass.
11
-DOOR WITH GLASS (the door should be checked and cleaned from time to time):
The boiler and ash must be completely cool.
The glass is made of high temperature resistant pyroceramics. If any damage is caused to the glass, replace the glass as
soon as possible before you use the boiler again. The glass must be replaced only by an authorized person.
− THE EXHAUST SPACE OF THE SMOKE FAN (it should be checked and cleaned every six months)
To clean the inner space for smoke discharge, first remove the cover i.e. plug at the bottom of the ash box casing and
insert the vacuum cleaner hose through this opening, so that you may vacuum any residual ash and ensure the proper
operation of the boiler, Figure 17
Figure 17
− GENERAL CLEANING AT THE END OF THE HEATING SEASON

The boiler and ash must be completely cool – unplug the power cable of the boiler.
At the end of the heating season, unplug the power cable of the boiler for safety reasons. It is very important to clean and
check the boiler as it is explained above.
After a longer period of use, the asbestos-free tape (band) for sealing (packing) on the door may become detached from
the door. This packing is stuck onto the door with high temperature resistant silicone. To repair this, fix the back (the back side
of the tape) of the sealing tape with the use of high temperature resistant glue. This is very important for good door sealing.
6.2. CLEANING and MAINTENANCE (for maintenance work ers)

− THE FLUE CHANNELS – CHIMNEY (these should be cleaned every six months or after burning two tons of pellets)
This wind resistant flue channel (chimney) must be checked and cleaned each year. This should preferably be done at the
beginning of the heating season. For the professional cleaning of these elements of the boiler system you should preferably
contact authorized professionals. The spots that should be paid special attention to during cleaning and that should be
cleaned particularly well are shown in Figure 18.
− INNER FIREBOX (every two weeks)
Figure 18.Spots to be cleaned at least twice a year
6.3. SPECIAL MAINTENANCE

Your boiler is a heat generator that uses pellets as solid biofuel. Due to this, special maintenance should be performed
once a year.
These works, previously explained, should preferably be performed at the beginning of the heating season.
The purpose of this special maintenance is to ensure the proper and efficient operation of the boiler.
7. IMPORTANT SAFETY INFORMATION

You have bought a top quality product.
12
The manufacturer will be always available to provide any further information you may need in relation to the label of the
boiler and the instructions for its assembly and installation in your geographical conditions. The proper installation of the
boiler in accordance with the instructions given in this Manual is very important for preventing dangers, fire or any defects or
malfunctioning.
The boiler operates with negative pressure in the combustion chamber. Because of this you must ensure that the flue pipe
is thermally sealed thoroughly.
DANGER
In the event of fire in the flue pipe, evacuate all people and pets from the room, turn the power supply off immediately
using the main switch in the house or by unplugging the power cable (the plug must always be easily accessible and free), and
immediately call firemen.
DANGER
Classic fire wood cannot be used.
DANGER
Do not use the boiler for burning garbage.
8. THE QUALITY OF FUEL PELLETS 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.
8.1. FUEL PELLET STORAGE

0
Pellets must be stored in a dry place which is not too cold. In fact, cold and wet pellets (with a temperature of around 5 C)
decrease the thermal power of the fuel and require additional boiler cleaning.
PELLETS MUST NOT BE KEPT NEAR THE BOILER. Keep them at least 2 metres away from the boiler. Handle pellets
carefully and avoid breaking them.
WARNING:
If sawdust or small – crumbled pellets are put into the funnel-shaped part of the boiler i.e. the fuel tank, these may block
the pellet (fuel) feeding. Such pellets may cause the electric motor driving the pellet feeding mechanism to burn out, or they
may lead to damages to the electric motor reducer. If you see any such small, crumbled pellets at the bottom of the pellet tank
or at the bottom of the screw conveyor when the tank is empty, vacuum them with a vacuum cleaner by inserting the vacuum
cleaner hose through the openings of the pellet grate.
9. CONNECTION OF THE HYDRAULIC INSTALATION

In order to reduce the risk of condensation, install a three-way mixing valve with a pipe thermostat when installing the
boiler.

IMPORTANT!
-Connection of the furnace to the hydraulic installation can be performed by qualified technician ONLY, and in accordance
with the present legislation of the country in which the installation is performed.
ALFA PLAM disclaims any responsibility in case of material or physical damage, or in case of malfunction, if the above-
mentioned recommendation were not implemented.
Furnace is designed for both central heating for one storey and central heating for multiple storeys.
Furnace is prepared for closed heating system. All installations should be in compliance with SRPS regulations (Serbian
technical regulations and standards).
Back side of a boiler with all connections is shown in Fig. 19.
14
Figure 19
-Pos. water outlet is connection with external thread R1’’ for pressure line,
-Pos. pipe of return water is connection with external thread R 1’’ for return duct.
10. PRESSURE LINE AND RETURN DUCT

Pressure line and return duct outlets on the boiler are 1’’ wide and they should not be reduced or constricted before first
forking. Use steel pipe 1’’ wide or copper pipe of 28 mm in outer diameter (or bigger).
During installation, pay special attention to pipes’ gradients which should be 0.5% (5 mm per meter), and to ventilation of
the system (boiler, pipes, radiators).
Put thermo manometer on pressure line that will show water pressure in the system and water temperature on the boiler
outlet.
11. FURNACE BUILT-IN COMPONENTS

-Furnace has following built-in components:
-safety valve,
-circulating pump,
-automatic air vent valve,
-expansion tank and
-fill and drain cock.
It is not necessary to built mentioned components in. Complete furnace has a big advantage since you do not need
additional room for components that are already built in.
11.1. SAFETY VALVE

Safety valve is positioned under the furnace lid on the pressure line. Inlet connector is R1/2". Valve opens at water
pressure of 3 bars. To get to the valve, you must take the right lateral side off (facing the furnace).
Connector of the safety valve outlet which is positioned on the rear side should be conducted into the sewers using pipes.
11.2. CIRCULATING PUMP

Furnace has built-in circulating pump Wilo type RS 25/6 – 3 positioned on the return duct R1‫״‬. Power of the pump is 93W.
It is electronically turned on and off according to the set water temperature.
Axle of the pump should be placed horizontally. Pay special attention to its position during connection with the installation.
To get to the pump, you must take the left lateral side off (facing the furnace).
11.3. AUTOMATIC AIR VENT VALVE

Automatic air vent valve is positioned on the pressure line, under the lid. Its purpose is to exhaust sufficient air from the
boiler.
To get to the valve, you must take the right lateral side off (facing the furnace) .
Valve safety cap should be loose, not too tight, so that the air could freely leave the boiler and remain of installation.
11.4. EXPANSION TANK

Furnace has built-in expansion tank with 10l volume. Function of the tank is pressure stabilisation in the boiler and in the
heating system installation. Factory setting of the pressure in the tank is 1 bar.
11.5. FILL AND DRAIN COCK

Purpose of the cock is filling and draining of the installation.
It is positioned on the rear bottom side.
15
Inlet connector is R1/2", and outlet connector has hose extension.
12. FILLING THE INSTALLATION AND PUTTING INTO OPERATION

Before heating season, entire heating system should be filled with water, ventilated, and the boiler should be properly
connected to the chimney, following above mentioned explanations.
Working water pressure is recommended to be 1 – 2 bars. Ideally between 1.2 and 1.6 bar.
Test pressure can reach 2.4 bars.
NOTE:
Furnace must not be used without water. It must be connected to the installation system with radiators with minimum
power of 8 KW.
13. PRACTICAL GUIDELINES FOR USING HEATING SYSTEM

-All connectors must be properly sealed and tightened. There must not be any water leakage.
-Complete installation should be checked with water under the test pressure of 2.4 bars before putting into operation.
-System should be drained at least once because of the dirt inside it.
-Make sure that all valves between furnace and installation are open.
-Make sure to release air from the boiler and heating system prior to putting into operation.
-During ignition and cooling fazes, furnace might change in volume in response to a change in temperature and that might
cause crackling noises. That is absolutely normal, since the construction is made out of steel and it could not be considered
as deficiency. A basic fabric setting guarantees proper functioning and prevents overheating.
14. FILLING WITH WOOD PELLET

Furnace is filled with fuel from the upper side by opening the lid. Put the wood pellets into the furnace; its capacity is
approximately three 15 kg bags, total 40 kg pellet..
To simplify this procedure, split it to two segments:
-Put the half of the bag into the furnace and wait until pellets reach the bottom. Ignite the furnace.
-After the furnace starts to work normally, add the pellet as needed.
-Never remove the safety grill from the reservoir. During pellet filling, make sure that the pellet bag does not get in touch
with hot surfaces.

For the adjustment of the temperature of the room and the water in the boiler, it is sufficient to press the buttons 1 or 2.
The display will show the current state of the set temperature (TSET ).
The boiler has been factory set with a temperature of water in the boiler of 65ºC and at room temperature of 20ºC.
By pressing the button 1, the message SET TEMP. WATER is shown (figure 29) i.e. adjusted value of the water temperature
in the boiler. Thus, with button 1 we increase and with button 2 we reduce the value of the temperature and in this manner we
adjust the desired value of the water temperature in the boiler. The temperature of water can be adjusted within the range from
40ºC to 80ºC. We recommend that you do not adjust the water temperature below 50 – 55ºC due to possible condensation of
the boiler, neither above 75ºC.

There are three types of programming of the boiler operation:
- Daily programming
- Weekly programming
- Weekend programming
Daily programming
This enables setting of the daily functions of the chronothermostat. The boiler can be ignited and switched off twice as
desired and this is regulated by programming, having in mind that sufficient time is required between the switching off and the
new ignition so that the boiler could cool. It is necessary that the time and date are precisely set (menu 01). The functions of
switching on and switching off of the boiler depend on these actions, so for this reason you must compulsorily adjust the
exact time. First press the button SET and the button 5 and enter in the menu 02 as shown in figure 42:
Figure 42
Press the button SET, the shown indication is same as in figure 43:

Figure50
Weekly programming
The weekly programmer has 4 independent programs at its disposal (4 times switching off and ignition). These 4 programs
can be combined for each day in the week, separately i.e. whether some of them will be active or not (OFF or ON). Make sure
that the programs are carefully set in order to avoid overlapping of the time of switching on and switching off.
Attention: carefully perform the programming, generally avoiding overlapping of the time activation and/or
deactivation on the same day in different programs.
The programming procedure is the following:
The first four steps during programming are the same as in the setting of the daily program (figure 42-45). Press the
button 4 and then press the button 5 twice and the display will have the same appearance as shown in figure 51.
Figure 51
Press the button SET and then the button 1 and activate the weekly programming (On) as shown in figure 49.
Figure 52
By pressing the button SET and then the button 1 we are setting the starting time of the boiler operation in the first
program, as shown in figure 50. Repeat the same procedure and set the time of switching off of the boiler in the first program
as shown in figure 51.
Figure 53
Figure 54
By pressing the button SET and the button 1 we activate (ON) or deactivate (OFF) the program 1 for the corresponding day
in the week starting from Monday, up to Sunday as shown in figures 55 and 56. The transition from day to day is performed by
pressing the button SET.
Figure 55
23
Figure 56
By pressing the button SET, a transition is made towards setting of another program and its activation for every day in the
week separately (in the same manner as it was done for program 1). Repeat the same procedure for the remaining two
programs (program 3 and 4). The indicator that the programming is active will be shown in the display.
Attention: Deactivate the daily program if you want to use weekly rogramming.
Weekend programming
The weekend programming enables programming, switching on and switching off of the boiler (twice a day) during the
weekends (Saturday and Sunday). Activate the weekend programming only if the daily and weekly programming has been
deactivated.
The first four steps during programming are the same as in the daily programming (figures 42-45). Press button 4 and then
press button 5 three times and the display will look the same as shown in figure 57.
Figure 57
By pressing the button SET, we activate the weekend program as shown in figure 58.

17. SECURITY MEASURES

Furnace is equipped with following safety devices:
-PRESSURE REGULATOR
Controls the pressure in the chimney. It stops transport spiral for the pellet when the outlet is clogged or when it faces
pressure (draught)
28
-FLUE GASES TEMPERATURE SENSOR
Measures the temperature of the flue gasses and allows furnace ignition o stops it if the flue gasses temperature goes
bellow set value.
-CONTACT THERMOSTAT IN THE FIREBOX OR ON THE SCREW FEEDER CASE
When a temperature exceeds safety values, furnace immediately shuts down.
- CONTACT THERMOSTAT IN THE BOILER
When a temperature exceeds safety values, furnace immediately shuts down
-WATER TEMPERATURE SENSOR
When water temperature gets close to 85ºC, sensor runs cooling cycles or automatically shuts the furnace down using
“ECO-STOP” option, in order to avoid blocking the temperature sensor.
-ELECTRICAL SAFETY
Furnace is protected from power surges with standard fuse located on control panel on the rear side of the furnace. Rest of
the fuses are located on the rear side of the furnace in order to protect motherboard (integrated cards and heat exchanger
cards).
-FLUE GASSES FAN
If the ventilator stops, motherboard blocks the pellet feed and emits alarm signal.
-HELICAL GEARED MOTOR
When helical geared motor stops working, furnace continues to work until the flame does not extinguish and until the
minimum cooling level is not reached.
-TEMPORARY OUTAGE
After short outage, furnace automatically starts cooling process.
-NO IGNITION
If during ignition there is no flame, furnace automatically changes to alarm status.
