6.9. Alarms
Pellet is a product obtained by compressing sawdust of dry, high calorie
wood. No additional binding agents are allowed during compression. As a
clean product of bio mass, pellets are CO2 neutral, i.e. they do not add to
the greenhouse effect. Wood as a main ingredient of pellet is renewable
energy source and fuel of the future.
Pellet combustion produces only 1% ash.
Energy value is around 5kWh/kg.
2kg of pellet corresponds to 1l of fuel oil.
Pellet combustion emits CO2 equal to the quantity used by tree
during its growth.
1m of pellet has a mass of approximately 640kg3.
How to recognize high-grade pellet:
Pellet must have cylindrical shape, pellet with 5-7mm diameter and length
of 10-25mm is recommended,
Cylindrical surface must be bright.
Humidity must be less than 10%.
Packaging must be hermetically closed, as pellet absorbs water.
If immersed in water, high-grade pellet shall fall to the bottom.
Low-grade wood, wood waste with oil-seed admixtures and binding agents
should be avoided.
Irregularities in operation cycle are followed by alarm sound and displayed messages
related to an on-going irregularity. Irregularity may apper if exhaust gas temperature is
higher than prescribed, due to aspirator temperature sonde, interruption in smoke
discharge, pellet not lighting during ignition phase, power outage, furnace turn-off.
Furnace packaging is removed during assembly, i.e. before initial start-up.
All materials can be recycled.
Packaging material (plastic bags, parts made of polystyrene, etc.) should
be kept away from children, as it is a potential source of danger.
Plastic parts of the packaging should be disposed of at a designated area,
not burnt down.
Safety measures should be taken as wooden parts of packaging have nail
connections and can cause injury when staffs are hammer forged and
If a failure is related to the aspirator temperature sonde, a message ALAR will appear
on the upper display and SOND on the lower one. The furnace will turn off after this
message. In this case contact the service center.
If the temperature of exhaust gases increases above the standard temperature set up
by the manufacturer, the message ALAR appears and HOT on the lower display. In
this case too, the furnace will turn off. If after repeated attempt to set the normal
working regime there is the same alarm sound, contact the service center.
If the pellet cannot be lit at the start, the message ALAR will appear, and on the lower
display, alternating signal ACC/NO will appear.
Note: this often happens at the INITIAL start of the furnace, when the hopper is empty.
In this case, turn off the furnace, open the door and empty the cast burner from pellets.
After burner is placed back and door closed, ignition should be attempted again.This
will ensure that there is enough pellet in the hopper itself at the initial start of the
furnace. Ignition may not be possible if the quality of pellet is not adequate or it is wet.
Also, ignition may not be possible in case there are foreign objects (plastic, pieces of
wood, impurities...) preventing the pellet to pass from the container into the hopper.
Check if the burner is cleaned.
If everything above described is in good order, fault is in the igniter, so, contact the
service center.
If there is a problem with smoke discharge, the message FAIL / DEL will be displayed
besides the message ALAR. Check if there is a physical obstacle for smoke discharge
in the chimney.
If the sonde on the pellet hopper register temperature higher than standard, ALAR will
be displayed and FIRE on the bottom display. Turn off the furnace. In this case, after
turning off the furnace on the thermic switch on the back of the furnace above the
switch (picture 3 position 15), unscrew the thermic switch lid and press the cylindrical
hopper, which returns the thermic switch into the operating mode.Try to start up the
furnace again when all required conditions are met.
If pellet gets extinguished during work, ALAR will appear on the upper display and
FIRE on the bottom one.This will be followed by sound signal.The most frequent cause
is the lack of pellets.
If there is a power failure during operation NO will appear on the upper display and
FIRE on the lower one. After power supply is normalized, turn off the furnace and
start it up again.

remote control unit), as well as the fire symbol with signs + and – (right side of
the remote control unit). The sign + increases and the sign – decreases the
value of temperature and capacity. Battery is not supplied with the remote control unit.
Battery P23GA (12V) should be used.
Pellet furnace - MBS pellet
Legal procedures related to safety and ecology must be followed.
There should be ample air where furnace is assembled for combustion purposes.
Connect the furnace to the voltage of 230V, 50Hz.
Convenience outlet must be realized in accordance with requirements of electricity
distributor and effective regulations.
The supply cable must be without any damage. It must not pass over furnace hot
surfaces, nor over other units which may melt or damage the cable.
Before furnace assembly, check if the chimney complies with requirements, if there
are any obstacles or cracks inside it. All iregularities should be removed before the
furnace start-up.
The furnace must not be placed near wooden elements, cooling units or plastic
furniture parts and other combustible material because it emits a very high operating
temperature during its work (at fuel combustion), distributed along the outer furnace
surface.The shortest distance between the furnace and other combustible elements
must be 25 cm from the back side, 25 cm sideways, and 80 cm from the front.
If the floor under the furnace is highly combustible (wood, linoleum, laminate..) it is
necessary to place tin protection excessing the furnace base dimensions: 10 cm
laterally, and 30 cm frontally.
The furnace should be connected with chimney with chimney lining through the
connection on the back side of the furnace ensuring adequate tightness and smoke
flow from the furnace towards the chimney. The chimney lining must not be too
deeply set back into the chimney in order not to reduce the surface of cross section
and thus disturb chimney draught.
Before furnace assembly, check chimney draught as it is one of the key factors
of the regular furnace work. Draught depends on the state of the chimney and
meteorological conditions. One of the simplest ways to check chimney draught
is the candle flame, as shown in picture 2. Bring the candle flame near the chimney
opening and if it bends towards the opening, draught is satisfactory (picture 1b).
Weak flame bending is an indicator of bad draught r (picture 1a).
Picture 1a
Picture 1b
If chimney draught is bad, check if chimney is in good order. The chimney should be
inside the sructure, and if it is on the external wall of the structure, chimney insulation
is recommended.
Pellet furnace - MBS pellet
Pellet furnace - MBS pellet
Chimney failures may be:
1 badly positioned windscreen,
2 foreign objects or bulges in the chimney
3 chimney cracks,
4 accumulated soot,
5 leakage of connecting areas and openings for cleaning,
6 too deeply set back chimney lining,
7 fire-place without door or some other opening on the chimney,
8 leakage of connecting areas and openings for cleaning.
No other device should be connected to the chimney connected with the furnace.
At the initial start-up, there is combustion of protective agents used in production and
storaging of furnace parts, of colour evaporation used to protect the furnace from
corrosion.That is why you should certainly ventilate the room in order to remove unwanted
At the initial start-up, we recommend the presence of a competent person of minimum 30
minutes, who should make sure that all requirements for safe furnace operation are met.
Make sure the furnace is correctly plugged in, connected with the chimney, at safe distance
from combustible materials, supplied with high-grade pellet and enough clean air for
combustion. On the back of the furnace, at the bootom left corner, there is a switch with
marks 0 and 1 (picture 3, position 16). When you ensure that all operating preconditions are
satisfied, turn on power supply by turning the switch into position 1 and follow further
instructions from the chapter ’Operating instructions’.
Picture 16
6.4 Setting up Program 2
If you wish the furnace turn on and off differently than already set by Program 1,
apply Program 2.
When the key SET is pressed, the message UT 08 is displayed (picture 17), and
keys 1 and 2 adjust the furnace turn-on time.
When the key SET is pressed, the message UT 09 is displayed (picture 18), and
keys 1 and 2 adjust the furnace turn-off time.
When the key SET is pressed, the message UT 10 is displayed (picture 19), and you
can set the days when you want Program 2 on with keys 1 and 2 in the following
way: key 1 selects the day of the week and the key 2 confirms if the program is on or
off on that given day (ON –program activated, OFF – program not activated on the
displayed day).
Furnace cleaning and maintenance
• During cleaning, furnace should be plugged out.
• Clean the furnace only when cold.
• Glass of the furnace should be cleaned with dry cloth. If needed, you can use water and
mild washing liquids, but only when the glass is cold. Abrasive agents damage glass,
so do not use them. Make sure that after glass cleaning you remove moisture and check if
it is dry before starting-up the furnace.
• Painted and vanished parts are not cleaned with abrasive agents as the protection is
removed in this way.
Use the solution of water and detergent. Carefully clean dirty parts with wet cloth or
sponge, rinse them with water after washing, and dry paint protected or electrostatically
vanished surfaces. Do not allow water to reach electrical parts of the furnace.
• Every day, after usage, when the furnace and ash cool down, remove ash from the firebox.
Use vacuum appliance when cleaning firebox.
• Empty the ashpan regularly but only when the furnace is not running.
• Ensure that pellet combustion container is clean and air flow openings always passable.

When the key SET is pressed, the message UT 07 is displayed (picture 16), and you can
set the days when you want Program 1 on with keys 1 and 2 in the following way: key 1
selects the day of the week (1 – 7) and key 2 confirms the day when the program is on.
For example:
After pressing key 1, ordinal day appears and the message OFF 1 (inactive Monday).
After pressing key 2, the program mode for Monday is displayed followed by the
message ON 1. If you do not activate key 2, Monday is not set to use Program 1.
Procedure is repeated for each day of the week. Key 1 selects the day, and key 2
activates a program for the displayed day.
• Once a month, clean the area behind ash-pan by removing the lid (picture 2). The
lid can be removed by unscrewing 4 bolts. Clean the chamber with vacuum cleaner
(picture 2). Before turning on the furnace, fasten the lid back. Also, remove the cast
lid (with the mark MBS on) from the firebox and clean the chamber behind with the
vacuum cleaner. Before turning on the furnace, fasten the chamber lid back.
