Fuel properties
Use of liquid or any other solid fuel other than wood pellets is strictly forbidden.
The main characteristic of this stove is that it burns natural fuel (wood pellets), which is ecologically produced from
waste in the wood-processing industry (chips/sawdust). Having been properlycleaned and dried, the chips and the sawdust
which are produced in the wood-processing processes, are compressed under extremely high pressure to produce small
cylinders of pure wood: pellets. Each tiny cylinder can vary in length and thickness, from 1 to 3 cm in length and 6 to 8 mm
in diameter.
Wood pellets are primarily distinctive by a low moisturecontent (below 12%) and high density (=600 kg/m3), as well
as with their uniformity and compactness, which gives thistype of fuel characteristics of high caloric value (DTV 4100-5000
kcal/kg).

Wood pellets that are used as fuel for this stove must have excellent quality properties such as the ones prescribed by the
standards DIN 51731, ONORM M 7135, and EN plus A1, for which numerous basic items are given below.
CAUTION: To achieve the best possible level ofoperation of the stove, we recommend the use of the wood pellets that
are verified by the accredited body. Use of pellet typesother than those defined by the manufacturer maycause defect of the
stove and annul the warranty.
Storage and handling of the wood pallets are importanttasks that must be performed carefully.
-The fuel must be stored at a dry and warm place.
-The pellets must be handled in such a way as to prevent theirexcessive crushing and becoming fine powder.
Adherence to these two simple rules shall enable better efficiency of the combustion and even preserve the proper
operation of the movable mechanical parts of thedevice.
CAUTION: If the device is not used for a sufficient period of time (more than fifteen days), all remaining pellets should
be removed from the tank in order to prevent their excessive moisture since it may lead to deterioration of the product.

INSTALLATION
To install the product successfully and avoid the occurrenceof failures, we give you below a number of simple advice for
assembling, in line with applicable relevant regulations. You must adhere to all local and national laws and the European
standards when installing, using and maintaining the device.
Placing the device
Our product produces heat by entering air necessary for the combustion process directly from the environment that is to
be heated.
For this reason, as well as for the reason of safety of users of the stove, the device has always to be installed within an
adequately ventilated environment to ensure a constant flow of air for combustion. Therefore, it is necessary to install
openings for the air intakethat is connected to the outside air (as shown in the Figure 2.1).
The openings for the air intake must have the following properties:
1. They must have internal cross-section not smaller than 80 cm2;
2. They must be placed at the approximate floor height;
3. They must be appropriately protected with a wire mesh ora grate in order not to decrease the minimal condition of the
radius for the air flow;
4. They must be installed so as not to be blockedin any way
5. Proper flow of fresh air can also be provided by using an opening to the adjacent room, if it is a room equipped with
direct ventilation and if it does not present a risk of fire, such as a warehouse, garage, or storage area.
You are recommended to avoid installation of the heatingdevice in rooms where there are devices that cannot operate in
a closed mode relative to the environment or in rooms where there are devices that can decrease the pressure inthe room
itself relative to the outside environment, since it can lead to problems of poor intake of air for our product.
CAUTION: It is forbidden to place the stove in a common chimney..
During the check of the system compatibility, you are recommended to verify that the supporting area (the floor) has the
adequate weight capacity (kg) to withstand the weight of the product. If this is not so, you are recommended to undertake
adequate safety measures (e,g.use of a panel for the weight distribution).
CAUTION: Place the external parts of the stove at a distance from any fuel or flammable material: 30 cm from the rear,
30from the lateral and 80 cm from the front side. Ifkeeping of theabove distances is not possible, please provide
corresponding thermal protection.
Figure 2.1: Example of required air intake openings
CAUTION: Never allow the flammable materials to get close to each other, or even get intocontact with theexternal surfaces of
the combustion chamber, since they may reach extremely high temperatures while the product is operational.
CAUTION: If the floor is made of flammable material (e.g. hard wood), you are recommended toprotect it by placing a layer
of non-combustible material below and around the stove.
During the installation phase, pay attention that the electrical cable is accessible when the installation is completed.
⚠CAUTION: The electrical cable must be equipped witha corresponding earthing terminal.

6
CAUTION: Avoid touching the electrical cableswith wet hands.
Figure 2.2: Maximum safety distance of the combustionmaterial [cm]
CAUTION: After determining the place where you will place the stove, it is possible to adjust the legs on the side of the
stove to achieve the desired height.. Twopersons are needed for the lateral movement of the stove. After you adjust the legs,
place down the stove very carefully.
Characteristics of the flue pipe
Main properties of the flue pipe are listed below:
-Inspection opening (I);
-Maximum height of the pipe directly connected to the opening of the flue exit on the stove must be 2 to 3 m;
-If you need a horizontal segment, please do not exceed 1.5 m in length and a slope of 3 to 5% in order to facilitate the
exit of smoke;
-Use a wind and water resistant end piece on the flue to minimize the change in draft value.
Use the end part that is resistant to wind and waterto prevent change of the state of somewhat larger pressure
of the flue pipe itself (do not place a horizontal part at theend of the flue pipe);
The state of somewhat larger pressure of the flue pipeis needed to make easier flow of the smoke from the combustion
chamber towardsthe outside environment.
Have in mind that any removal of excessive heat ismade by the electrical controlpart (modulation, extinguishing, etc.).
-The exhaust channel must be made of materials that are resistant to the products of combustion and to moisture (the
check shall enable removal of any kind of moisture);
-The channels should be manufactured in such a way as toprevent any smoke leakage;
-The channel should be insulated, especiallythe external part that is exposed to weatherconditions.
Avoid using completely horizontal segments.
Figure 2.3: Exhaust channel
The room where the heating system is to be installedshould not have hoods since they may reduce the pressureof the
environment.
Closing of air openings is strictly forbidden.
The exhaust channel must be cleaned at least once ayear; we recommend thorough cleaning of both the exhaust
channel and its connections.
After a period of inactivity and before the start,check that there is no congestion.
CAUTION: The exhaust channel must be constructed in line with the provisions of applicableregulations.
CAUTION: Check with the appropriate tool whether the chimney has a minimum (draft) of 10 Pa.
One of the solutions that may be applied includes installation of the wood pellet stove near the external wall ofthe house
tolet the exhaust gases escape directly to the outside environment. (Figure 2.4). Some notes highlighted by the standard for
30

this type of system configuration are given below:
-Always ensure that there is an inspection opening (I) to allow for regular cleaning procedures as well as the removal of
moisture that may form.
-The chimney pot (T) must be made so as to be resistant towind and water;
-Pay attention that the chimney is properly insulated in the part that passes through the wall.
If the flue is located entirely outside, it must be made of double wall stainless steel to ensure greater resistance to
atmospheric conditions, as well as the correct temperature of the exhaust gases themselves.
Figure 2.4: Smoke exhaust toward the external wall
Flue gases of a stove may be removed via a traditional, already constructed chimney (Figure 2.5), if it meets the applicable
standards. The main properties of a good chimney (Т) are concisely listed below:
-Proper insulation, first of the external part that is exposed to atmospheric conditions;
-Constant internal diameter (there must be no segments with a smaller diameter);
-It must be made of material that is resistant to high temperatures, to the effects of the combustion product and to
corrosion effect of the moisture that may be formed;
-Mainly vertical position, with no deviations ofvertical angles exceeding 45°.
We recommend that the base of the chimney is equippedwith a chamber for collecting of solid particles or moisture(R).
The chamber must be accessible via hermetical door (I).
Figure 2.5: Smoke exhaust towards the roof viatraditional chimney
It is recommended to follow the guidelines established by the standards UNI 9615 and UNI 9731 in relation to the size
and diameter of the chimney (T). However, never use an exhaust duct with an internal diameter of less than 100 mm.
In the case of exhaust ducts with a larger diameter, a steel pipe (A) must be placed inside the brick or mortar of the
chimney (C), as shown in Figure 2.6.

Figure 2.6: Example of the connection with the chimney
In case of fire in the chimney or the flue pipe, immediately extinguish the stove and disconnect it from the power system.
Disassembling and waste disposal
The packaging consists of materials that are not toxic or harmful. There is no need for special conditions for its
disposal. Disposal of other components of the packaging is the responsibility of the user. He/she must perform
corresponding disposal procedures in line with applicable standards in the country where the product is installed.
CAUTION: Packaging elements must be kept out of the reach of children not supervised or persons withdisabilities.
Electrical connections
Connect the product to your household power supply.
Just press the main switch on the back of the device if you want to turn on the device. After you do this, the stove is
ready for ignition. For processes ofignition and programming, refer to Section 3.1.
Room temperature measuringdevice
The room temperature meter allows the temperature in the room where the stove is installed to be continuously
monitored. This device enables permanent monitoring of thetemperature in the room where the stove is installed.
Installation of the room temperature measuringdevice at an appropriate place shall enable proper workof the product.
Electrical scheme of connection
For completeness, the electrical scheme of connection is provided. The sheme is specifically intended for technical
personnel responsible for installation and maintenance.
CAUTION: The main switch does not guarantee that the stove will be disconnected from the power supply. Therefore,
the cable of the stovemust be disconnected fromthe socket before the coverings or screws that hold the section of the
integrated circuit in place are removed.
In order to test the electronic card, it is necessary to remove the coverings on the left side.

USING THE PRODUCT
Before we describe in detail the operation of the product, we would like to remind you that, while using it, you must
observe the relevant national and local provisions, rules and applicable laws. For a better understanding of how the
product works, diagrams of the display control panel are shown, followed by a detailed description, as well as what needs to
be done to start the stove for the first time. The product is easily ignited whenthe electrical cable is connected and the
button IGNITION is pressed.
To ignite the stove, connect the electrical cable to thepower socket and press the ignition button on the rear
During the several first ignitions of the stove, vapours and unpleasant odours may spread from painted parts.
Theseinconveniences are a necessary result ofthe process of chemical stabilisation of special dyes that are used; therefore,
good venting of the room is necessary in this phase.
CAUTION: Pay attention for the door of the stove to be closed while the product is operational.
CAUTION: Although surface temperatures reached by our product are not excessively high, you are recommendedto be
careful when touching them. Especially the external surfaces of the combustion chamber can reach high temperatures during
long-term use.
CAUTION: Place the external part of the stove at a distance from any fuel or flammable material: 30 cm from the rear, 30
cm from the lateral and 80 cm from the front side. If keeping of theabove distances is not possible, please provide
corresponding thermal protection.
To avoid failures that may lead toinjuries and damages to persons or property, you are recommended to avoidsudden
and constant ignition and extinguishing of the product, but to follow the schedule provided by the manufacturer for these
procedures.
CAUTION: The house wiring must be equipped with grounding (in good condition), otherwise the electronic card may
malfunction.
We recommend not to use the stove in an instable supply mode: continuous power cutsmay lead to failures.
You are recommended to clean the chimney and theconnections with the flue pipe thoroughly (at least once during the
whole heating season)in order to prevent the risk of fire.
Pay attention that the door of the stove isclosed while the product is operational.
Any unauthorised change on the deviceis forbidden.
Use only replacement parts recommended by themanufacturer.
First ignition
Pay particular attention to cleaning the burner before starting the ignition process and check whether the braid under the
burner is tight, i.e. whether it rests with its entire surface on the burner support.

10
Proper operation of the device is performed when there isno uncontrolled air inlet; therefore, the door SHOULD be firmly
closed and, in the same way, it is necessary to check whether all other ways are closed except the intended one. Therefore, it
is a good habit to check that the door seal adheres well to the chamber, over its entire circumference (whether it seals well).
Regulation related to the installation of pellet products EN14785 provides that it is necessary to have a vacuum of10 Pa on
the basis of the chimney, so special attention must be paid to the smoke removal system. If the chimney is lower, if there are
too many flue pipes, the air intake required for combustion (which can change and affect the combustion itself) is also lower.
The lower and more bended the flue pipe is, the lower the air intake required for combustion (which may change and affect the
combustion itself). Slow smoke flow incertain cases may cause the increase of temperature that creates a change ofthe
operating power.
Since there are different types of pellets in the market, the operation of the product must be adjusted for the specific type
of fuel that will be used.
To allow the user to adjust the stove for different pellet typesand different installation types, the user’s menuoffers four
types that are indicated in the ascending order from 1 to 4. The ascending order of the type indicates the higher ventilation of
the system. In the extreme case, if neither of the factory types provides efficient combustion, it should be remembered that
the operating parameters can be changedONLY with the support of specialized technicians of ALFA PLAM a.d. who will
specifically analyses the situation and provide the best solution for any case.
In order for the stove to heat up properly, it is recommended that you set the power of the product to value "4" or to value
"5" during the ignition phase and a few minutes after.
To provide more assistance to the user, please find below a sequence of steps that should be undertaken in order to switch
on the product.
1) Fill the tank with pellets to the optimal level. We recommend that you do not completely fill the part for fuel intake,
the optimal level is achieved by adding fuel until it touches the grid with openings in the tank..
2) Connect the product onto the power socket.
3) Press the switch at the rear of the stove.
4) Follow the instructions described in section 3.3.
CAUTION: Do not place your hand for whatever reason inside the auger for loading of pellets while the stove is

EXTINGUISHING OF THE PRODUCT
Press and hold the Ignition button for a few seconds. The stove shall initiate the extinguishing process as set in the
planning phase (the extinguishing interval is variable andmay take a few minutes).
CAUTION: You are recommended not to interrupt theextinguishing process before it is fully completed by, for
example, disconnecting the product from the power socket.
If the flame goes out due to the lack of pellets, switch off the stove. You need to put more fuel in the tank and restart
the ignition process only when it is off.
It is forbidden to insert pellets into the burner by hand.
CAUTION: The door of the stove must always be closed when you are using it; its opening is allowed only for the
purpose of maintenance, when the productis cold.
Change of the stove is not possible.
Unsolicited repairs, as well as the useof spare parts that are not genuine or unauthorized replacement of parts of
the product, as well as thecancellation of the warranty may lead to failures andserious risks for users who are in

Safety devices
The product is equipped with the following safety devices:
•Thermostat for determination of the tank temperature: this device switches off the operation of the product any
time the set safety limit is exceeded;
•Device for measuring the smoke temperature: this element determines the smoke temperature and constantly
monitors the proper operation of the product;
•Pressure switch: this element determines whether there is a clogging of drains, i.e. flue pipes;
•Ambient thermometer: this element constantlymonitors the temperature in the room where the stove is located;
•Operation modulation mode: if the smoke temperature exceeds the set safety threshold, the device automatically
decreases the quantity of pellets for combustion until thetemperature drops below the set limit.
Incorrect parameter settings can lead to exceeding the safety limits and can lead to excessive consumption of pellets.
Exceeding of the safety limits may also occur due to the poor ventilation of the environment where the stove islocated, which
do not provide sufficient cool air for the device.
Safety devices MUST NOT be switched off. When the cause for activation of the safety system is eliminated,the device
can be started again in order to restore its proper functioning.
CAUTION: The device must be installed so as toprovide easy access to its electrical cable.

Turning the furnace on and the state function
The furnace is turned on by long pressing P2 for 3 seconds. After that come the next function states of the furnace:
During the check up phase the initial checks of the input signals or the probity of safety probes and pressure switches of
the furnace are done. In this phase the flue gas engine runs at maximum speed while the auger and igniter are turned off.
The check up phase lasts for a few seconds, and a successful check up is followed by the ignition phase.
The ignition phase consists of four sub phases which alternate, and those are:
- Preheating phase
- Pellet preload phase
- Fixed ignition phase
- Variable ignition phase
The message IGNITION is displayed during the entire ignition phase. There are no special markings on the display for
sub phases.
3.6.2.1 Ignition Preheating
At this stage there is warming of the igniter before dispensing of the pellets starts. In order for pellet burning to be as
efficient as possible, it is desirable that the igniter is already preheated at the time when dispensing the pellets starts. At
this stage the igniter is active and the auger is inactive. Flue gas engine runs on lower rpm in order to promote heating of

15
the igniter.
3.6.2.2 Ignition Preload
In this phase there is the initial dispensing of pellets or the auger loads a certain amount of pellets necessary for
ignition. In this phase the igniter, auger and flue gas engine are active.
3.6.2.3 Ignition –Fixed Phase
This phase is a fixed time period that lasts for 180 seconds and in case that the furnace ignition requirement is reached
before the expiry of this phase it will always last until the end and only after the expiration of the fixed time period will the
furnace move into stabilization phase. In this phase the igniter, auger and flue gas engine are active.
3.6.2.4 Ignition –Variable Phase
This phase occurs after the fixed ignition phase. The duration of this phase is a variable period that lasts until the
moment of fulfillment of the ignition requirements or until the moment when the flue gas temperature of 50 °C is reached. In
case the furnace ignition requirement is met before the expiry of the duration of this phase, it is stopped and the next phase
follows, which is the stabilization phase. In this phase the igniter, auger and flue gas engine are active.
The stabilization phase is a transitional phase between the ignition phase and the run mode phase. This phase occurs
when the ignition requirement is met, that is, when flue gas temperature reaches 50 °C. It lasts for three minutes and during
that time the auger, flue gas engine and the igniter are active.
The normal run mode begins following the stabilization phase. In this phase there are five levels of power that can be set
up as explained in the user menu 1. In this phase the igniter is turned off while the auger, flue gas engine and area engine
are active and run with different intensity depending on the level of power of the furnace. The furnace runs on the given
power until the modulation requirements are met.
The furnace goes into the modulation phase when one of the two conditions are met:
1. When the furnace reaches the preset ambient temperature
2. When the flue gas temperature reaches a value greater than 250 °C
In the modulation phase the furnace runs on minimal power - power 1, until the moment when the temperature
decreases below the threshold value.
The Safety status occurs when flue gas temperature exceeds 275 °C. In this phase dispensing the pellets stops until the
temperature of flue gases decreases. If there is no decrease in temperature in the next 60 seconds the furnace goes into an
alarm stage and displays the Er05 message.
The furnace is turned off by long pressing P2 for more than 3 seconds. The extinguishing phase occurs next during
which dispensing of pellets stops and the flue gas engine and the ambient fan operate at maximum capacity in order for the
furnace to cool down as soon as possible. Minimum duration of the extinguishing phase is 30 seconds and the requirement
for the furnace to completely turn off is for the flue gas temperature to be less than 68 °C.
During this phase the furnace is turned off, that is, no furnace output (flue gas engine, ambient fan, igniter and auger) is
active.
The block state occurs in the event of a fault or alarm. In the block state the exhaust gas fan, auger and igniter are
turned off. To exit press P2 for 3 seconds: if there is no more block and no cause for alarm the system will turn off.
The furnace goes into this phase in two cases:
1. If there is a power failure in the operating mode and the flue gas temperature is greater than 50 °C.
2. By pressing the main switch at a time while the furnace is in the extinguishing phase.
Other functions
In the absence of power, the system keeps the most important functional data. When the power is restored the system
evaluates the saved data and:
If the furnace is turned on and the temperature of exhaust. gases is greater than 50°C, the system enters
the recovery point. Pressing P1 can lead to a sudden new system ignition.

16
If the furnace is turned on but the temperature of exhaust. gases is lower than 50°C, the system enters the
shutdown point with error Er15.
If the furnace is turned off or in extinguish or block phase, the system returns to its previous state.
In the absence of power for more than a week the system goes into block with an error message Er11
indicating that the DATE/TIME values are incorrect. When P1 is enabled the TIME value starts to blink signaling the
need for updating the TIME and DATE with the CLOCK function.
The user has the option to calibrate the dispensing of pellets in the user menu 1. Calibration ranges between -7 ÷ 7.
1=5%. Each calibration of dispensing the pellets is applied to all workforce in percentages. For example, if -1 is set up then
the dispensing of pellets will be reduced by 5% in all operating modes (Power 1 - 5).
Example
Before calibration
Power 1 = 2.0
Power 2 = 3.0
Power 3 = 4.0
Power 4 = 5.0
Power 5 = 6.0
Step = -1
Power 1 = 1.9
Power 2 =
2.85
Power 3 = 3.8
Power 4 = 4.75
Power 5 = 5.7
Never calibrate dispensing of pellets without consulting with the service center first.
The user has the option to calibrate the rpm of the flue gas engine in the user menu 1. Calibration ranges between -7 ÷
7. 1=5%. Each calibration is applied to all workforce in percentages. For example, if it is set up to 3 then the rpm of the flue
gas engine will be increased by 15% (3x5%) in all operating modes (Power 1 - 5).
Example
Before
calibration
Power 1 = 1000
Power 2 = 1200
Power 3 = 1400
Power 4 = 1600
Power 5 = 1800
Step = +3
Power 1 = 1150
Power 2 = 1380
Power 3 = 1610
Power 4 = 1840
Power 4 = 2070
Never calibrate the rpm of the flue gas engine without consulting with the service center first.
In the event that the temperature in the pellet tank reaches the value higher than 90 °C, the safety thermostat activates
in order to prevent the ignition of pellets in the tank. The system goes into block mode and there is an alarm message Er01.
When the system is stable after a specified time interval (every 45 minutes), the system automatically performs periodic
cleaning which lasts for 30 seconds.
During the periodic cleaning, the flue gas engine works with increased intensity while dispensing of pellets stops.
When the system shuts down during the ignition phase (after the preheating phase) through an external device or an
internal chrono device, the system goes into shutdown mode when it enters running mode at the end of ignition phase.
Message Block ignition is shown on the display.
If an error occurs, the system immediately goes into shutdown; if P2 is pressed, it is possible to immediately introduce
the system into the turning on or off.
