Ariterm Biomatic+ is a cost-effective, resistant and environmentally friendly combination of
a central heating boiler and a pellet burner intended for use for the heating of single-family
detached houses and the production of hot domestic water using pellets. Additional/backup heat is produced by an incorporated electrical resistance (9 kW). Standard equipment
includes an automatic convection cleaning system and an automatic heating circuit regulation
system. Detailed technical data can be found on page 3. To make use of all features of the
boiler and burner, it is important to observe these instructions.
Keep this manual in a safe place for future reference. Read this manual carefully before starting to use your Ariterm Biomatic+ pellet heating centre. The power of the pellet burner depends on how many pellets can be fed into and burned in the burner head during one hour.
(This means burning of wood pellets of the usual kind, which approximately comply with
the fuel specifications described in this manual.)
Please note! Follow the recommendations contained in this manual when using and servicing
the burner and the boiler.
TRANSPORT, STORAGE AND PACKAGE OPENING
Receipt and acceptance
The boiler is delivered in a wooden frame. The base is a platform from which the boiler can
be safely lifted. The package should be unwrapped as close to the installation site as possible.
The factory has insured the boiler against damage during transport from the factory to the
first intermediate storage site. It is important for the person who receives the boiler to verify
the state of the boiler before its acceptance. In case of damage, the dealer must be contacted
without delay.
Storage
The boiler can be stored outside under a rain cover for a short period of time. However, the
preferred option is to store it inside.
Package opening
After opening the package, open the hatch and check the accessory list to make sure that all
loose accessories are contained in the package (cleaning brush handles are attached to the
package).
Disposing of the package
The plastic cover is landfill waste and the boards can be burned.

FUNCTIONAL DESCRIPTION
SAFETY AND ALARMS
Heating with the Ariterm Biomatic+ pellet heating centre is similar to oil heating in many
ways. The main difference is that heating with solid fuel produces a certain amount of ash,
which must be removed at certain intervals. If the ash is not removed, combustion efficiency
will decrease and the burner may malfunction.
The BeQuem pellet burner is equipped with automatic ignition. However, it can also be ignited
manually when necessary. The electric ignition system of the burner will only be activated during cold starts, i.e., when the system has been inactive for a long period and the boiler temperature has dropped to at least 8°C below the target temperature. During the heating process,
the necessary ignition cycles take place by means of the embers in the burner head. This saves
electric energy.
The burner and the incorporated feeding
system operate automatically. The operation of the burner is controlled by the temperature sensor installed in the boiler. The
burner head contains an accurately defined
mixture of fuel and air, which ensures perfect combustion which is both cost-effective
and environmentally friendly.
The auger burner is over-pressurised during operation. The purpose of this is to reduce the risk of damage to the burner if the
draught is weak.
For safety reasons, the pellet heating centre and fuel store must be placed apart from each other
to prevent possible damage. Any malfunctions or damages caused by incorrect handling will
then be limited to the burner. The fuel store must be built as a separate, fire-classified, confined
space.
Faults that cause the system to stop are indicated by a red indicator light. In addition to this, a
text message appears on the display indicating the cause of the fault.
During every operating cycle, a small amount of pellets (150 g) is fed from the pellet store via
the external feeding system to the upper connection of the burner. To make it possible to dispense an accurate and equal amount of pellets during every cycle, the dispensing is carried out
by means of a separate feeding auger via the blocking feeder and auger burner to the burner
head.
As the auger burner feeds pellets forward three times faster than they arrive at the auger, a safety zone, containing only single pellets, is created between the burner head and the upper connection. This safety zone always remains intact even in the event of power failure, insufficient
maintenance or equipment breakage.
Alarms are described in "Troubleshooting".
Wood pellets with a diameter of 6 or 8 millimetres (not in combination) are the recommended fuel for the boiler.
Ash is removed from the ash box located in
the lower part of the boiler. Ash can also be
removed into a special ash pan by means of
an ash trap or a common vacuum cleaner.
However, the ash may still be hot. Therefore,
the ash trap must be heat-resistant.
Standard equipment includes an automatic
heat regulation system that adjusts the supply water temperature according to the temperature outside.
ARITERM-VTT-S-07229-11.1
The feeding auger must be installed in such a way
that its position with respect to the drop funnel
enables the drop pipe to hang free outside the
burner should a fire occur in the back.

BOILER INSTALLATIONS
BOILER INSTALLATIONS
The boiler should be installed by a company with the proper professional qualifications. The
installation must always be carried out in accordance with, at the time being, valid local standards and regulations.
NOTE!
All electrical connections must be carried out by a professionally-qualified electrician.
Space requirement
The boiler room must always meet, at the time being, valid local standards and regulations. At
least one meter of free space is recommended to be left in front of the boiler for cleaning and
maintenance operations. It is also recommended to leave about 80 cm of free space on the other
side and at least 50 cm above the boiler.
NOTE!
The boiler must located be at a distance of no less than 180 mm from the back wall. In addition, it
must be possible to remove the flue gas fan whenever maintenance requires it.
Flue pipe connection and combustion air intake
Silicon sealant with a temperature resistance of 350°C can be used as a sealing compound for
joints. The flue pipe must be made of steel or equivalent material. The flue pipe length must
be dimensioned according to the building requirements. The ventilation air intake must not be
covered.

Ventilation air intake
100 cm2
* Measure the vacuum in the measurement hole on the left-hand side of the burner. Slacken off
the black screw.
NOTE! The vacuum in the chimney is not critical because the boiler is equipped with a suction fan.
However, it must be dimensioned to be able to evacuate the flue gases without overpressure occurring as the flue gases could then leak into the building.
ARITERM-VTT-S-07229-11.1
Pipe installations
Before installing the boiler, the heating network must be flushed and checked by means of a
water-pressure test. After installation, make sure that all joints are tight. The factory is not
responsible for damages caused by leaking joints.
Dirt trap and manometer installation
It is recommended that the dirt trap delivered with the boiler be installed in the cold water
pipe before the heat exchanger. There is no manometer in the boiler. Therefore, it must be
installed in the heating network.
Safety valve installation
The valve must be CE marked. Its maximum opening pressure must be 1.5 bar and its minimum size DN 15. The safety valve must be chosen according to the highest pressure class of
the combination of devices. Devices that can close the connection must not be installed between the valve and the boiler. The blowdown pipe must be dimensioned and installed in such
a way that it does not limit the valve blowdown efficiency and does not cause dangerous situations during the operation of the valve.
Electrical installations
A pellet burner, a 9 kW electrical resistance and an internal circulation pump with its switches
are installed in the boiler and are ready for use. The boiler contains an overheat protection for
the burner and the electrical resistance. The electrical installations related to the boiler must
be carried out by an installer with the relevant qualifications. The connection is carried out according to the enclosed connection diagram. A safety/maintenance switch must be installed in
the voltage supply system of the boiler.
Before commissioning
Before starting the boiler, the following should be checked:
• the heating network and the boiler are full of water (pressure at least 0.5 bar).
• air is removed from the internal circulation pump through the venting screw located in the
pump head.
• the flue damper (if any) is open.
• the circulation damper located in the convection part of the boiler is in place.
• the circulation pump is running.
• the network valves are open.
• the ventilation air intake is open.
• the safety valve is in working order and there are no obstacles between it and the boiler.

START-UP AND STOP
Burner start-up and stop
Turn the burner and the internal pump on from the operating switch. If the flow switch that
controls the internal pump is on, set the operating switch to Off mode. The main menu, which
shows the temperatures of boiler water and flue gases, will appear on the display. The main
menu also shows the Start-up/Stop setting and mode of the burner. If the buttons are not
pressed for 10 seconds, a graphic showing temperature and burner data will appear on the display.
The first start-up differs from normal start-up in that there are no pellets in the burner. Likewise, there are no pellets in the external feeding system.
Power mode - Maintain mode
After ignition, the burner starts using the Max power range. When the boiler water temperature rises to within 4 ºC of its set value, the burner starts using the Mean power range and
will continue to use it until the set value is reached. When the target boiler water temperature
is reached, the burner blower still runs for one minute before the burner moves to Maintain
mode (heating method off ). While the burner is in Maintain mode, the auger burner brings
pellets to the burner head every now and then in order to maintain the embers. (Setting “Ember maintenance”)
Carry out the following actions in connection with the first start-up or if there are no more pellets in the store:
1. Turn the external auger on from the main menu and wait until pellets arrive at the upper
connection of the burner The external auger will automatically stop after 15 min (the setting can be changed).
2. Set the burner to ON mode.
Stop
The burner can be stopped at any stage of the combustion process. Set Burner to Off in the
main menu. The blower will continue to function for one minute after the burner has been
stopped.
Cold start
The burner performs a cold start by means of the ignition resistance when the boiler water temperature is more than 8°C below the set value. The Burner setting shows the message
"Start-up 1K", the auger burner turns on and so does the red indicator light. Shortly afterwards, the blower and the ignition resistance turn on. A cold start consists of seven phases
(1K-7K). When the flame detection system detects a flame in the burner head, the burner
moves directly to phase 5K and the green indicator light turns on. When starting directly from
phase 7K, the burner stops for 10 minutes in order for the combustion process to normalise in
the burner head. If the flame does not ignite after phase 7K, the burner gives a cold start alarm
as described in "Troubleshooting".
Do not change the settings during a cold start. After cleaning the burner head, make sure that
the burner performs a cold start because there are no embers in the burner head. The success
of the cold start can be ensured by sufficiently increasing the set boiler water temperature and
by changing it back to the desired value after ignition.
Use as accumulator
As an option an Accumulator tank sensor can be connected to the boiler, an addition to which
a charging pump (a load pump) can also be controlled. The load pump is to be connected to
connectors 14 and 15 (230 vac) and the tank sensor to connectors 63 and 64.
The Load pump-setting is taken in to use from the Accessories-menu. This will automatically
put the Holding time setting to off-mode. The burner’s starting- and stopping temperatures
can now be set. These are controlled by the tank sensor. Load pump’s starting temperature is
set by the Load pump diff-setting. When the boiler temperature exceeds the Set temperature - Load pump diff-setting, the pump will start. When the tank has warmed and the burner
stopped, the pump will go off when the boiler water temperature has dropped by 2 degrees
from the set temperature.
Hot start
The burner performs a hot start when the boiler water temperature is within 8°C of the set
temperature, for example, after a short power failure. During a hot start, the burner uses the
embers in the burner head for ignition and, by doing so, saves energy. In normal use, when the
burner goes from Maintain mode to Power mode, the burner performs a hot start. The burner
starts up automatically after power failures (hot or cold start depending on the temperature of
boiler water).

BURNER SETTINGS
BURNER PARTS
The settings for combustion and burner operation can be found in the Power menu.
Combustion adjustment
In most cases, the factory settings are sufficient for proper and efficient combustion. In addition, they can be applied when the underpressure in the combustion chamber is about 8-15 Pa
and the pellets used have a diameter of 8 mm. In connection with commissioning, it is recommended that the values be adjusted by a skilled installer by means of a flue gas analyser. Carbon
monoxide (CO) should be less than 200 ppm and excess air (02) 6.5-8%.

If combustion is poor, the smoke coming from the chimney is black or if the ash produced is
granular, adjust the ratio of fuel to air from the Power menu. Pellet feeding to the burner head
can be adjusted through the High auger and Low Auger settings. The amount of air required
for combustion can be adjusted through the High Fan and Low Fan settings. The Min settings
are not available.
Adjustment example - External auger operating time
The level switches located in the upper connection of the burner measure the amount of pellet
fuel in the burner and control the external storage auger. When the pellet surface drops below
the level switches, the external auger activates (factory setting 30 s). The operating time of the
external auger should be long enough for the pellet surface to rise to the level of the burner upper connection. Time can be adjusted from Auger External in the Power menu. If the time is
too long, the pellets rise to the drop pipe level. In this case, pellets may accumulate in the pipe,
which would cause the Pellet Shortage alarm to be given. If the time is too short, there is not
enough time to bring pellets. As a consequence, the same alarm may be given.

Electrical resistance operation
Electrical resistances can be activated from the Burner Adjustments menu. If a 9 kW resistance
is used, set the setting to 3. In this case, 9 kW will be reached in stages (3 kW -> 6 kW -> 9
kW). If the fuse is not sufficient for 9 kW, the setting should be 2, where only 6 kW is available.
The Activation Start Backup El setting is used to determine how much the boiler water temperature must decrease with respect to the set temperature before the electrical resistances turn
on (Heating method: pellets + electricity). If the burner has malfunctioned or stopped, the
electrical resistance functions as a source of backup heat. If heat is set to be produced only by
means of electricity, the electrical resistance tries to keep the boiler water at the set temperature.
For example, if the temperature difference of the electrical resistance is set to 20 ºC, the electrical resistance turns on at 58 ºC as long as the set boiler water temperature is 80 ºC. After heating the water to 62 ºC, the electrical resistance turns off. Settings: Heating method: pellets +
electricity and El step = 1

The feeding rate of the storage auger can be determined, for example, by driving the storage auger for 10 minutes and by measuring the weight of the pellets which arrived at the vessel. Multiplying this by six gives how many kilograms the storage auger brings in an hour (kg/h). The
feeding rate may vary according to pellet quality.
The Pellet Store setting is used to determine the amount of pellet fuel in the store. The automatic equipment calculates the consumption of pellets on the basis of the feeding rate and
operating time of the external auger. In addition, it estimates whether the amount of pellet fuel
will suffice for one day on the basis of average consumption.
The Alarm Pellets Min setting is used to determine the limit at which a message warning about
the termination of pellets appears on the burner screen.

Residual oxygen (accessory)
The value of the residual oxygen measurement can be seen in the main menu and in the
graphic. The measurement is not available in Maintain mode. This saves energy and the sensor. Adjust first the power of the fan so that the oxygen value is between 7% and 8%. The cycle
in Power mode should be as long as possible in order for the combustion session to normalise.
Then, set the Residual Oxygen setting to On mode from the Accessories menu. After this, if
the residual oxygen level becomes too low, the burner will automatically increase the fan power
in order for combustion to remain good. The residual oxygen measurement gives an alarm
when the value becomes too low. The power source for the oxygen sensor must always be connected if the burner is in use, otherwise the sensor can become dirty and function will be impaired.
Tachometer
The tachometer measures/checks the blower rotation speed, which can also be seen in a graphic on the screen. If the fan is blocked or broken, the tachometer detects the fault and stops the
burner.
Flue gas fan
The boiler is equipped with a flue gas fan. The fan power can be set to Power mode or Maintain mode. The setting can be made in the Accessories menu (Smokegasfan Max and Min).
The flue gas fan power must be controlled so that there is a vacuum of 8-15 Pa in the fire box.
Metering can be carried out via the hole blocked by a screw under the flame sensor.
Automatic convection cleaning system
The automatic convection cleaning system reduces the amount of cleaning needed by the boiler
and maintains the burner’s high efficiency. (NOTE! See page 20). The operating time and
pause time for cleaning are determined as needed.
ARITERM-VTT-S-07229-11.1
Heat regulation
The standard equipment of the Ariterm Biomatic+ pellet boiler includes a heat regulator that
can be used to control at most two heating circuits. A temperature graph for supply water temperature adjustments can be created for each circuit. Heating circuit 1 can be fine-adjusted by
means of the indoor temperature sensor. In addition, the automatic equipment contains a circulation pump control outlet that depends on outdoor temperature. Standard delivery includes
the control kit for heating circuit 1, the shunt motor/valve and the temperature sensors (supply
water, outdoor and indoor temperature).
Electrical installations
The terminal blocks for shunt motors and temperature sensors are under the front panel. The
same applies to the circulation pump control. The connection must be carried out according to
the connection diagram. NOTE! It is recommended to keep the wires of the temperature sensors separate from the feeding cables. Use the lead-ins on the right-hand side of the boiler roof
for the temperature sensors. The wires of the temperature sensors should be kept as short as
possible. NOTE! If the outdoor temperature sensor is detached or broken, the outdoor temperature is 0 ºC by default.
In connection with floor heating, it is important to determine the supply water min and max
values for the temperature graph. With parquet floor, the supply water temperature should not
rise above 45ºC. In these cases, it is recommended to install a thermostat for the circulation
pump control. The thermostat switches the pump control off if the supply water temperature
rises above 45ºC. If the supply water temperature is too high, this may damage parquet floor.
General information
The temperature graph determines the supply water temperature according to the outdoor
temperature. The colder it is outside, the warmer the supply water. However, in connection
with radiator heating, the supply water temperature increases exponentially when the outdoor
temperature decreases. With a correct temperature graph, the room temperature is pleasant regardless of the temperature outside.
Stone floors may feel cold in summer. In this case, the supply water temperature can be set to
at least 22-25 ºC to keep the floor pleasantly warm. In this situation, take into account the Circulation Pump Stop setting. Heating circuit 1 may also be equipped with an indoor temperature sensor. The indoor temperature can be set to a certain value. The temperature graph can
be fine-adjusted in order to reach this value. The room coefficient can be used to determine the
supply water correction coefficient in order for the indoor temperature to reach the set value.
The factory setting is 2 ºC. In other words, if the indoor temperature is 19 (20)ºC, the supply
water temperature increases by 2 ºC in order for the set indoor temperature to be achieved.
The room coefficient depends on insulation level and heating system.

Floor heating system
A thermostat is installed in the circulation pump control of the heating circuit. The thermostat
switches the pump control off if the supply water temperature rises above 45 ºC. If the supply
water temperature is too high, this may damage parquet floor.
Control
If, when the outdoor temperature is below 0 ºC, the room temperature is too low, slightly increase the Curve setting. Correspondingly, if the room temperature is too high, decrease the
setting. In summer, the Flow Water Min setting can be used to ensure a comfortable floor temperature.
If the room temperature feels too high or too low while the outdoor temperature is between -5
ºC and +5 ºC, the shape of the graph can be modified through the Curve comp. settings. The
settings can be used to increase/decrease the supply water temperature.
If an indoor temperature sensor has been installed, the sensor automatically corrects the supply water temperature to obtain the desired indoor temperature. The room coefficient is used
to determine how many degrees the supply water temperature must decrease in order for the
room temperature to increase by 1 ºC.
ARITERM-VTT-S-07229-11.1
The Drop menu can be used to determine the two times when the supply water temperature
is decreased by a set value. Set first the right time so that the drops are carried out at the right

Boiler water temperature
The Pellet boiler Ariterm Biomatic+
can be equipped with a heated oxygen
sensor that facilitates control of the
burner and which if necessary can
regulate the combustion air fan output
if the combustion is poor. Residual
value is displayed on the display- The
heated oxygen sensor can be easily
connected to the boiler at a later date.
The package includes heated oxygen
sensor, control circuit board, power
source and wiring with connector.
With the control unit (accessory) one can replace the room temperature sensor included in the
boiler.
Control module
The unit with the display is located centrally in the room. The unit includes a temperature
sensor, according to the automatic heating controls finely adjusts the flow temperature. The
unit also gives information about temperatures and the boiler function (electrical resistor and
alarm).
Installation
1. Slacken off the screw in the
boiler’s flue and install the probe in
the threaded hole.
Installation
The unit is installed according to the wiring diagram with screened twisted pair cable (4x0.22
or for example telephone cable). The connection is made directly on the boiler’s control circuit
board. If the display is blank or shows the alarm Com.Err, the connection is faulty. Check
the connections and check the cable if necessary.
2. Install the control circuit board
for example on the boiler or wall
beside it so that the cables reach
the probe and the boilers control
circuit board.
NOTE! The room temperature sensor that is supplied with the boiler must be deactivated, if
the room temperature unit is connected. The room temperature unit can be installed for the
Ariterm Biomatic+ 20 from manufacturing number.
3. Connect the probe’s connector
and the cable for metering signals
to the connection on the reverse of
the boiler (Oxygen)
The set room temperature can be changed with the OK button. The value
is changed by pressing Plus and Minus. Hold OK pressed 7 seconds, the
Service menu comes up, and the following settings can be changed:
• Background lighting power

Use
1. The heated oxygen sensor’s power source must always
be activated when the burner is used. The probe can
otherwise become dirty at which function is reduced.
NOTE! The probe is hot when the current is connected.
2. First set the combustion air fan output, so that the
residual oxygen value is 7–8 %. The output is adjusted
in the Output menu with the settings High fan and
Intermediate fan. These values must not be changed.
Normal operating phase should be at least 30 minutes
long, so that the combustion is stabilised in the combustion chamber.
3. Then select ”yes” for Residual oxygen in the Accessory menu. The automatic control then regulates the
combustion air fan output if the residual oxygen level is
too low and combustion too poor. This can happen if the
combustion head is dirty or the supply voltage falls. If the
residual oxygen falls below 4 %, the boiler gives an alarm
signal and the burner stops. If the Residual oxygen is set
to “no”, the residual oxygen value is shown in the display,
but alarm and control is missing.

ALARMS AND TROUBLESHOOTING
In case an alarm becomes active, this is indicated by the burner on the display of the control
panel with a red light and a text message. This facilitates troubleshooting, because the user
can see the cause of the problem. The burner stops in connection with an alarm. The cause of
the fault must be determined before switching the device on again. If an alarm is given often,
this may be due to incorrect adjustments/settings. When the red light blinks, the burner display shows a warning message, for example, about the fact that it is time to empty the ash box.
However, the burner functions normally. Acknowledge by pressing the C button. In order to
check and service the burner, it is first necessary to cut the voltage supply and detach the burner connection wires before removing the burner from the boiler. After this, the burner cover
can be detached and the inspection of the flame detection sensor or other component can be
carried out.
Alarm message / Cause
The burner has stopped and the display
is dark.
Voltage is no longer supplied to the
burner.

1. Are there pellets in the burner
head?
The flame detection sensor has not detected any flames in connection with a
cold start. The alarm is given 10 min after the end of the cold start.
2. Operation and cleanliness of the
flame detection sensor
1. If the burner head does not contain pellets but the upper connection of the burner does, try to reignite.
Make sure that the burner head receives pellets.
2. The operation of the flame detection sensor can be checked by reflecting light on it. How the sensor
reacts to it can be followed from the
Burner Adjustments menu. The flame
detection sensor may have become
dirty due to weak draught. This prevents the sensor from recognising
flames. See "Inspection and Maintenance".
3. Go to the Testing menu and turn
the blower and the ignition resistance on. Make sure that the resistance
heats up and ignites the pellets.
Procedure
1. See "Alarm cold start" (paragraph 2).
2. Go to the Testing menu and
turn the blower on. Make sure
that the blower works.

After a hot start, the flame detection
sensor has not detected any flames for
10 minutes. The embers have all burnt
and the burner does not use any ignition resistance when performing a hot
start. After cleaning the burner head,
the boiler water temperature may be
within 8ºC of the set temperature. In
this case, the burner will try to perform
a hot start. Since there are no embers,
the alarm will be activated.
If the flame detection sensor becomes often sooty or overheated, this may be due to faulty
adjustments or insufficient vacuum in the furnace. In these
cases, contact the installer. The
vacuum in the firebox can be
increased by raising the exhaust
extractor output in the menu Accessory. See page 14.
1. Operation and cleanliness of the flame detection sensor.
2. Ember maintenance time (Power

Ember Maintenance setting.
If the alarm has been given after cleaning the burner head,
increase the set temperature of
boiler water temporarily in order
for the burner to be able to perform a cold start.
1. Clean the burner head and
open the air vents.
Alarm residual oxygen
Residual oxygen has been under 4.5%

SERVICE AND MAINTENANCE
The boiler and burner will function without problems for a long time if the following instructions are observed:
• The boiler must be kept in a dry environment
• The boiler and burner operate all the time within the defined adjustment values.
• Clean the boiler when the temperature of flue gases has increased by 20-30°C with respect
to the temperature they have with a clean boiler.
• Check the burner head and clean it as needed. Remove the sintering and, if necessary,
scrape the air gaps open.
• Replace the damaged part with a new one in due time
• Check to make sure that no condensed water or water coming from pipe leaks can damage
the boiler.
Note! Always disconnect the main power before maintenance work!
Check every 1-2 years
Unfasten the burner primary air ring, which is fastened by means of four screws and nuts.
Clean the air vents of the primary ring and remove all ash. At the same time, check the primary
air pipe and clean it of ash. The burn cup should be sealed with fireproof sealant.
Detach the protective casing of the burner. Check the chain wheels and chains for wear or
whether the chain has loosened. Adjust and change as needed. Lubricate the chain with thin
oil.
Note!
Always remember to be careful when dealing with ash because it may still be incandescent. The
ash must be stored in a fire-resistant vessel.
Boiler cleaning
Turn the burner off for about an hour before maintenance work and cut the main power. Clean
the furnace from the burner opening and the convection part from the cleanout hatch on the
top of the boiler. Clean all convection pipes with the cleaning brush delivered with the boiler
(see the next page). Finally, empty the ash box. The ash from the ash box can be used to determine whether combustion has been good. The ash should be powdery.
The interval for ash removal and boiler cleaning can be specified in the Service menu on the
basis of experience. The boiler should be cleaned when the temperature of flue gases rises by
20ºC with respect to the temperature they have with a clean boiler.
Burner cleaning
Turn the burner off for about an hour before maintenance work and cut the main power. Pull
the burner out of the boiler, check the burner head and carry out the necessary operations. The
burner head does not usually need special maintenance. However, in connection with ash removal, it is good to check whether hardened ash has accumulated in the burner head. To detach the hardened ash, use a screwdriver or similar tool. At the same time, check whether ash
has flown to the mouth of the flame detection pipe and clean it as needed.
In connection with a new fuel delivery, the burner head must be checked in order to detect
possible sintering (mutually bound ash, rock and gravel-like particles in the burner head) over
time. Such particles must absolutely be removed from the burner head at short intervals so that
the primary ring will not become overheated and get damaged.
Sintering is often due to impurities in the fuel. If this is the case, you should immediately file a
complaint with the fuel supplier. Pay special attention to pellet quality when you receive a new
delivery or when you change suppliers.

Burner quick locking
clips
Burner slide bar
Ash box fastening handles
Burner cleaning is started by unfastening
the quick locking clips on both sides of the
burner and by pulling the burner out of the
boiler.
Make sure thatthe burner wires do not get
damaged.
The burner’s combustion chamber is cleaned
so that the burner and the ash box are
withdrawn from the boiler after which the
combustion chamber is emptied directly into
the ash box.

BOILER CLEANING
Automatic convection cleaning system
The boiler is equipped with automatic convection cleaning system
that automatically carries out the sweeping at certain intervals. In
any case, the convection channels must be cleaned (swept) two
times a year.
The cleaning is done through the cleanout hatch on the top of the
boiler. The automatic sweeping system must be removed before
sweeping. Disconnect the main power before maintenance work.
Other boiler cleaning operations
Convector cleanout hatch
Flue duct cleaning
Remove all ash and possible sintering from the
combustion vessel. The primary air intakes and the
ignition resistance opening must be open.
Clean the metal pipe of the flame detector so that
the ash accumulated in the pipe will not hinder the
operation of the flame detector.
Convection channel
cleaning 2 times a
year.
Clean the flame detector of impurities.
Pull the flame detector out of its pipe with caution
and hold on to the rubber lid.
Combustion chamber cleaning
(as needed)
NOTE!
If the protective glass of the flame detector breaks
or detaches, the flame detector can no longer be
used and must be replaced with a new one.

WOOD PELLETS AS FUEL
Wood pellets are renewable bioenergy and provide fuel in a compact and uniform form, which
is easy to handle. The moisture content is less than 10%, which means that the pellets do not
freeze or become mouldy. No chemical substances are used in the manufacturing process. Instead, the binding agent is the tree’s own lignin.
Fuel recommendation
Raw material
Chemically untreated, barkless wood
Diameter
8 mm
Length
15-32 mm
Volume weight
over 600 kg/m3
NOTE!
The Ariterm Biomatic + series boilers are suitable for burning pellets of diameters ranging from
6mm through to 12mm. The burner is factory set for 8mm wood pellet having a mean density of
650kg/m3. Minor readjustment of the burner setting is required when utilizing alternative sizes/
densities of pellet.
Moisture content
less than 10%
Ash content
less than 0.7 weight %
Fine material content
max 4 weight %
Ash melting temperature
> 1,100 °C
Most of the disturbances that occur as a result of bad fuel quality are caused by incorrect handling and intermediate storage before the product is delivered to the customer. Large contents
of fine materials may be due to insufficient sifting. Ash sintering is often caused by silicate
impurities (sand). These materials cannot be detected before burning. NOTE! If the ash is sintered, all sintered material must be continuously removed from the burner head.
Energy content
>4.75 kWh/kg
The pellet diameter is 6 to 12 mm and the length is 10 to 30 mm. Due to their small size, the
pellets move freely in the feeding augers.
Fuel storage
Thanks to the feeding system, it is possible to build the pellet store for so-called bulk deliveries.
The store can be placed either inside or in a separate building outside the house. The shorter
the transport distance from the store to the burner, the better the feeding system functions.
Fire regulations must be taken into consideration when designing the boiler room and the storage area.
The entire store must be insulated with extreme caution in order to prevent dust from spreading.
The pellet delivery methods must be taken into account when choosing the store size. In general, the pellets can be obtained in small sacks (20 kg), large sacks (500 kg) or directly to the
store by means of a blower truck. One tonne of pellet fuel requires about 1.6 m3 of storage
space. The smallest delivery batch for loose pellets is three tonnes. A store of 8 to 10 cubic metres is a reasonable solution for many houses and involves lower delivery costs.

FEEDING SYSTEM
Weekly silo PF300
The lightweight silo is an alternative to the self-built silo. The practical PF300 may also be
used as intermediate store for pellets. The capacity of the pellet silo is 300 litres and its filling is
facilitated by the intermediate grid in the silo. Contrary to the figure, the silo is delivered with
a lid.
NOTE!
More information on the installation of PS300/Feedo can be found in separate manuals.
ARITERM-VTT-S-07229-11.1
Depo
Feed chute Depo is a patented pellet transfer system that effectively, reliably and quietly feeds
pellets from the silo via the feeding system to the burner.
Feedo
Feedo is a pellet feeding system designed to work with feed chute Depo.
NOTE!
More information on the installation of Depo/Feedo can be found in separate manuals.

DECLARATION OF CONFORMITY
The Clean Air Act 1993 and Smoke Control Areas
Under the Clean Air Act local authorities may declare the whole or part of the district of the
authority to be a smoke control area. It is an offence to emit smoke from a chimney of a building, from a furnace or from any fixed boiler if located in a designated smoke control area. It is
also an offence to acquire an “unauthorised fuel” for use within a smoke control area unless it is
used in an “exempt” appliance (“exempted” from the controls which generally apply in the smoke
control area).
The Secretary of State for Environment, Food and Rural Affairs has powers under the Act
to authorise smokeless fuels or exempt appliances for use in smoke control areas in England.
In Scotland and Wales this power rests with Ministers in the devolved administrations for
those countries. Separate legislation, the Clean Air (Northern Ireland) Order 1981, applies in
Northern Ireland. Therefore it is a requirement that fuels burnt or obtained for use in smoke
control areas have been “authorised” in Regulations and that appliances used to burn solid fuel
in those areas (other than “authorised” fuels) have been exempted by an Order made and signed
by the Secretary of State or Minister in the devolved administrations.
Further information on the requirements of the Clean Air Act can be found here : http://
smokecontrol.defra.gov.uk/
Your local authority is responsible for implementing the Clean Air Act 1993 including designation and supervision of smoke control areas and you can contact them for details of Clean Air
Act requirements
The Ariterm Biomatic+ series boilers have been recommended as suitable for use in smoke
control areas when burning wood pellets.
