Fuel properties
The furnace is first characterized by the fact that it burns natural fuel (wood pellets), which is environmentally derived
from the wood industry waste (chips/sawdust). Once shavings and sawdust are properly cleaned and dried, which arise in
the wood processing procedures, they are compressed under extremely high pressure to produce small cylinders of pure
wood: pellets. Each tiny cylinder may vary in length and width from 1 to 3 cm in length and from 6 to 8 mm in radius.
Wood pellets are primarily characterized by low humidity (below 12%) and high density (= 600 kg/m3), as well as their
uniformity and compactness, providing this type of fuel with high calorific value features (DTV 41005000 kcal/kg).
Wood pellets which are used as fuel for this furnace must have excellent quality characteristics, such as, for example,
those defined by the following standards: DIN 51731, ÖNORM M 7135 and EN plus A1, with basic numeric items listed below
⚠ATTENTION: As is required by the relevant European laws governing the characteristics of commercial fuels, pellets
must be manufactured exclusively using shavings of unprocessed wood without added matter.
s is strictly prohibited.
⚠ATTENTION: In order to bring furnace operation to the highest level, the use of wood pellets certified by an accredited
body is recommended. Using other types of pellets compared to those specified by the manufacturer can lead to failure of
the furnace and may void the warranty.

1A maximum of 20% of pellets may have a length 7.5 times larger than the diameter D
2DIN prohibits the use of any added substances. However, this prohibition does not apply to small heating systems.
3Up to 5% of pellets may have a length greater than 40 mm, and a maximum of 45 mm.
⚠ATTENTION: If the appliance is not used for a sufficiently long period of time (more than two weeks), all remaining
pellets should be removed from the tank to prevent it from becoming too wet as this can lead to failure of the product.
Storage and handling of wood pellets are important tasks which must be done carefully.
- Fuel must be stored in a dry and warm place.
- Pellets must be handled as to prevent too many crushed pellets that become fine powder.
Compliance with these two simple rules will allow better combustion efficiency and will even help maintain proper
operation of moving mechanical parts of the appliance.
Safety recommendations
⚠ATTENTION: Carefully read the attached user guide with the instructions before installing.
⚠ATTENTION: The firebox must be empty before the appliance is turned on in case
of any difficulty when turning the device on.

Safety devices
The product is equipped with the following safety devices:
•A thermostat for determining the temperature of the tank: this device shuts down operation of the product each time
it exceeds the set safety limit;
•Meter for determining the smoke temperature: this element determines the smoke temperature and continually
monitors the proper functioning of the product;
•Pressure switch: this element determines whether there is a clogging in the pipe;
•Thermometer for the environment: this element constantly monitors the temperature of the room where the furnace
is located;
•Operation modulation mode: if the flue gas temperature exceeds the set safety threshold, the appliance will
automatically reduce the amount of pellets for burning until the temperature drops below the set limit.

6
Incorrect parameter settings can lead to exceeding of the safety limits and can lead to excessive consumption of pellets.
The safety limits can also be exceeded due to poor ventilation of the room in which the furnace is located, which does not
provide the appliance with enough cold air.
Disabling the safety devices is PROHIBITED. When the user eliminates the cause of activation of the security system,
the appliance can be restarted in order to restore its proper functioning.
⚠ATTENTION: The appliance must be installed in such a way so that its electrical cable is easily accessible.
specified in chapter 3. ALFA PLAM bears no responsibility for any personal injury or property damage that may occur if the

B) Do not remove or modify any safety devices on the appliance;
C)The appliance must be connected to the system for smoke removal which is functioning properly;
D)Make sure that the surrounding area in which the furnace is set is sufficiently ventilated, as prescribed in this user
guide.
Surrounding area for using the product
⚠ATTENTION: The appliance must be installed in a surrounding area with ventilation, and it must be provided with
sufficient air combustion in accordance with the applicable regulations. This is important for ensuring its proper operation.
⚠ATTENTION: The room must have a volume not less than 20 m3and must possess all the necessary ventilation
conditions, as described in Chapter 2 of this user guide. These conditions will provide the necessary air flow to allow for
proper combustion (40 m3/h).
Using the product in the bedrooms and bathrooms is PROHIBITED.
Using the product in spaces with another heating appliance which does not have its own system for air intake is
PROHIBITED.
Placing the product close to flammable materials is PROHIBITED.
Placing the product on the floor made of flammable material unless a protective plate is used made of non-flammable
materials is PROHIBITED.
Using the product in explosive and potentially explosive atmospheres is PROHIBITED.
Installation
You must comply with all local and national laws and European standards when installing, using and maintaining the
appliance.
Positioning the appliance
Our product creates heat by bringing the necessary air in for the combustion process directly from the environment which
needs to be warmed up.
For this reason and because of the basic safety of the users of the furnace, the appliance should always be installed
inside an adequately aired out area to ensure a constant flow of combustion air.
Therefore, it is necessary to place the air intake vents that are connected to the air outside (as shown in Figure 2.1)
In accordance with the provisions set forth in the UNI 10683 standard, air intake vents must have the following
characteristics:
1. They must not have an internal cross-section of less than 80 cm2;
2. They must be placed at an approximate height of the floor;
3. They must be adequately protected by wire mesh or grate so that the minimum radius condition for air flow is not
diminished;
4. They must be placed so as not to be blocked in any way.
Correct flow of fresh air can also be ensured by using the opening to the next room, if that room comes equipped with
direct ventilation and does not pose a risk of fire, such as a warehouse, garage or storage, as set forth by the UNI10683
standard.
It is recommended that you avoid placing a heating device in the rooms with devices which cannot work in a closed
manner compared to the surrounding area or in the rooms where there are devices which can reduce the pressure in the
room itself compared to the external environment, as this can lead to problems with low air intake for our product (UNI
10683).
⚠ATTENTION: It is forbidden to discharge combustion products of the furnace in a common stovepipe.
When checking the system compatibility, it is recommended to determine if the support surface of the support (floor)
possesses adequate load capacity (kg) to support the weight of the product. If this is not the case, it is recommended to take
appropriate safety measures (for example, use a distribution board).
When installing the furnace, it is advised to place it at the appropriate distance from the wall to allow access to the back
side of the furnace (we recommend at least 20 cm) and to the side (we recommend 80 cm). Such a space may be necessary,
for example, in order to be able to adequately clean the product.

7
Figure 2.1: Example of the necessary vents
Never allow flammable materials to come close or, indeed, come into contact with the outer surfaces of the combustion
chamber as it can reach extremely high temperatures when the product is running.
If the floor is made of flammable material (e.g. hardwood), it is recommended to protect it by placing a layer of non-
flammable material under and around the furnace.
More information on the minimum safe distance from flammable materials (see figure 2.2.a):
- Minimum distance from combustible floor (H = 4 cm);
- Minimum distance from combustible rear wall (B = 50 cm);
- Minimum distance from combustible side wall S = 40 cm);
- Minimum distance from combustible material on the front side (Fr = 150 cm).
Once you've determined where you will place the furnace, it is possible to adjust the furnace feet in order to achieve the
correct height. Tilting the furnace to the side requires two people. After you adjust the feet, carefully lower the furnace (see
Figure 2.2.b).
Figure 2.2: Distance when setting up
Stovepipe properties
The main properties of the stovepipe are listed below, based on the requirements of the standard:
-The inspection valve (I);
-Maximum height of the pipe which is connected directly to the smoke drain on the furnace should be between 2 to 3
m;
A
A

-If you need a horizontal segment, it should not exceed 1.5 m in length and a slope of 3 to 5% in order to help drain the
smoke;
Use the back part which is resistant to wind and water in order to prevent change of state of a slightly higher pressure in
the stovepipe (do not put a horizontal part at the end of the stovepipe);
The state of a slightly higher pressure in the stovepipe is needed to facilitate the flow of smoke from the combustion
chamber.
Keep in mind that any removal of excess heat is done by the electric control part (modulation, shutting down, etc.)
-The exhaust duct must be made of materials that are resistant to combustion products and moisture (a review will
enable the removal of any moisture);
-Ducts must be manufactured in a way as to prevent any leakage of smoke.
-The duct must be isolated, especially the outer part, which is exposed to atmospheric conditions.
using fully horizontal segments
Figure 2.3: Exhaust duct
The room in which the heating device will be assembled should not have hoods because they can reduce the pressure
of the surrounding area.
It is strictly prohibited to close the air vents.
The exhaust duct should be cleaned at least once a year; we recommend that you perform a thorough cleaning of the
exhaust duct and its connections.
ignition after a period of inactivity.
⚠ATTENTION: The exhaust duct must be built in accordance with the provisions of the standard.
⚠ATTENTION: Check if the chimney has a minimum pulling power of 10 Pa using the appropriate tools.
Smoke exhaust to the outer wall
One of the solutions that can be applied includes storing the furnace that uses wood pellets near the outer wall of the
house so that the exhaust fumes are directly released outside (Figure 2.4). Some of the notes set forth by the standard for
this type of system configurations are listed below:
-Always make sure that there is an inspection valve (I) in order to enable regular cleaning procedures, as well as the
removal of moisture which can be formed;
-The end of the funnel (T) must be such that it is resistant to wind and water;
-Make sure that the stovepipe is properly insulated in the part that passes through the wall.
If the stovepipe for draining the exhaust gases is completely outside, it must be made of a double stainless steel wall to
provide greater resistance to atmospheric conditions, as well as proper temperature of the exhaust gases themselves.
Draining smoke to the roof through a traditional funnel
Furnace exhaust fumes can be removed through a traditional funnel that is already built-in (Figure 2.5), if it meets the
applicable Standards and features the main characteristics of a good funnel (C), which are briefly listed below:
-Proper insulation, first in the outer part which is exposed to the atmospheric conditions;
-The constant inner radius (there cannot be segments with a smaller radius);
-It must be made of a material which is resistant to high temperatures, to the effects of the combustion products and
to the corrosive effects of moisture which may be formed;
-A mostly vertical position without deviating from the vertical angles greater than 45 °.
It is recommended that the base of the funnel is equipped with a chamber for collecting solid matter and moisture (R).
The chamber must be accessible through a hermetic door (I).

9
Figure 2.4: Draining smoke to the outer wall of the chimney Figure 2.5: Draining smoke to the roof through a traditional
chimney
It is recommended that you follow the guidelines set forth in the standards in relation to the size and radius of the chimney
(C). In any case, never use an exhaust duct with an inner radius smaller than 100 mm.
In the case of the exhaust ducts of greater radius, there must be a steel pipe (A) within the funnel bricks or mortar (C), as
shown in Figure 2.6.
The steel pipe must be insulated using a suitable heat-resistant material, such as rock wool or vermiculite (B), and it
must be separated from the outer part of the funnel.
Figure 2.6: An example of connection to the chimney
In case of fire in the chimney or stovepipe, immediately turn off the furnace and disconnect it from the electrical system.
Dismantling and waste disposal
The packaging consists of materials which are not toxic or harmful. No special conditions are needed for its disposal.
The user is responsible for the disposal of the remaining components of the packaging. The user must follow the proper

The necessary checks and controls for the first ignition
The following guidelines must be followed when first igniting the product:
•Make sure all safety requirements have been met (see section 1.8);
•Connect the appliance to the power supply only when you are sure that the voltage power supply is 230 V 50 Hz.
When you’ve made sure of this turn the switch on the back panel to "ON” - switched on;
•Make sure that the display on the control panel is turned on, which indicates that the appliance is properly plugged
into the power supply;
•Make sure there is enough fuel in the tank for the planned period of operation.
The fuel must be in accordance with the instructions given in the relevant section of this guide.
Painted parts of the furnace can emit smelly fumes during the first few ignitions. This phenomenon is associated with
a chemical process of stabilization of used paint. For this reason, during this period the room where the furnace is located
must be regularly and properly ventilated.
Loading the fuel
Open the upper door of the product to insert the pellets. You must comply with regulations with regard to the fuel
contained in the relevant part of this user guide.
⚠ATTENTION: Do not let the bag with wooden pellets come into contact with hot parts of the product while you load the
fuel.
⚠ATTENTION: Do not remove the protective grid inside the part for loading the pellets.
⚠ATTENTION: Do not lean the full weight of the bag containing the fuel to the product.
⚠ATTENTION: Close the upper door when you have finished loading the pellets.
Periodically check the amount of wood pellets contained in the tank and fill it up in time.
⚠ATTENTION: Excessive moisture can crush the pellets into fine powder, which can lead to increased sedimentation in
the boiler area, and even block the insertion/loading system (auger).
When inserting the pellets make sure that the pellets do not accidentally fall into the other inner parts of the appliance
except into the appropriate tank.
Only use pellets with a diameter of 6 to 8 mm.

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:
Check Up
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.
Ignition
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.
4.5.2.1 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 the
igniter.
4.5.2.2 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.
4.5.2.3 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.
4.5.2.4 Ignition –Variable Phase

16
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.
Stabilization
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.
Normal –Run Mode
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.
Modulation
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.
Safety
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.
Extinguishing
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.
OFF
During this phase the furnace is turned off, that is, no furnace output (flue gas engine, ambient fan, igniter and auger) is
active.
Block
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.
Ignition Recovery
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
Management of the absence of power
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.
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.
Management of pellet loading calibration
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).

Never calibrate dispensing of pellets without consulting with the service center first.
Management of flue gas engine correction
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).

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.
Safety thermostat
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.
Periodic cleaning of the furnace
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.
Shutting down during the ignition phase
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.
