•6 mm pellet must be used as fuel.
•Please do not put water on the boiler during operation.
•Attention should be paid to the pellet boiler operating pressure.
•Do not plug off while operating, please initially switch off, this operation is very
vital for the cooling of the boiler.
•The boiler should not be installed in open, humid areas.
•Take care of flue pipe standart sizes, the problems in case of using nonstandard
sizes will not be under our responsibility.
•Installation, electrical connection, function test and maintenance must only
be carried out by authorised and qualified personnel.
•Any change on the boiler should be done by authorized person or company.
•A bad use or improper maintainance of the product can bring to explosion in
the combustion chamber.
•Only spares parts adviced by producer should be used.
•Install the product in accordance with all local and national legislation and
regulations in force in the region or state.
•Do not put linen on the product to dry. Any drying racks or similar objects must
be kept at a safe distance from the product. Fire hazard.
•The pellet has been placed inside the tank. Please do not put your hand inside
while the stove is working.
•The product must be installed in accordance with the legislation of the
country where it will be installed.
•This product should be used by adult people
•Please do not operate the boiler before cleaning the combustion pot.
•Improper installation, use, and inadequate maintenance can lead to increased
failures. Malfunctioning is mainly due to the combination of part or all of the
following factors:

5
oCombustion pot holes obstructed or combustion pot deformed, due to lack
of maintenance and conditions which can cause delayed ignitions,
generating an anomalous production of unburned gases.
oInsufficient combustion air due to a reduced or clogged air inlet duct.
oUse of smoke ducts nonconforming to regulatory installation requirements,
failing to guarantee an adequate draught.
oPartially clogged chimney, due to lack of maintenance, reducing the
draught and making ignition difficult.
oEnd chimney pot nonconforming to the indications of the instruction
manual, and therefore not suitable to prevent potential inverse draught.
•The doors/covers on the appliance must remain closed when it is not used.
•If there is a fire in the flue pipe, extinguish the boiler, disconnect it from the
power supply and never open the door. Then contact the competent
authorities.
•In the event of fire in the chimney, turn off the device, disconnect it from the
mains electricity and do not open the hatch. Then contact the competent
authorities.
•Do not stand for a long time in front of the product in operation.
•Install the product in a location that does not present a fire hazard and is
equipped with power and air supplies and smoke extractors.
•The product and the cladding must be stored in a dry place and must not be
exposed to weathering.
•In the event of a malfunction with the ignition system, do not force it to light
by using flammable materials.
•Disconnect the product from the 230V power supply before performing any
maintenance operation.
•This factor is crucial when the product is installed in especially windy areas,
such as costal regions. The combination of one or more of these factors could
generate important malfunctioning conditions. To keep this from occurring, it
is fundamental to guarantee that the product is installed in compliance with
standards in force. Furthermore it is of the utmost importance to respect the
following simple rules:
oPellets must never be loaded in the combustion pot manually, either
before ignition or during operation.

6
oThe accumulation of unburned pellets ensuing a failed ignition must be
removed before repeating ignition. Also check that they are fed correctly
and that the combustion air inlet/smoke outlet are regular.
•If ignition fails repeatedly, immediately suspend use of the product and
contact a qualified technician to check its operation. Compliance with these
indications is absolutely sufficient to guarantee proper operation and to avoid
any type of problems with the product. If the above-mentioned precautions
are not taken, and during ignition the combustion pot is overloaded with
pellets thus generating anomalous smoke in the combustion chamber,
carefully follow the indications below:
oDo not disconnect electrical power to the product for any reason what ever:
this would stop the smoke extractor, releasing smoke into the environment.
oTake the precaution of opening the windows to ventilate the installation
room from any smoke in the environment (the chimney might not work
properly).
oDo not open the fire door: this would compromise regular operation of the
smoke extraction system to the chimney.
oJust switch the boiler off by acting on the on-off button on the control panel
(not the rear power supply socket button!) and move away until smoke has
completely evacuated.
Before attempting re-ignition, clean the combustion pot and its air passage holes
completely of all deposits and unburned pellets. Put the combustion pot back in
place, removing any residue from its support base. If ignition fails repeatedly,
immediately suspend use of the product and contact a qualified technician to
check its operation and the chimney.

2.1 PELLETS
Wood pellets are manufactured by hot-extruding compressed sawdust which is
produced during the working of natural dried wood. The compactness of the material
comes from the lignin which is contained in the wood itself, and allows the
production of pellets without the use of glues or binders.
The market offers different types of pellet with characteristics which vary
depending on what mixture of woods is used. The diameter varies between 6 mm,
with a standard length in the range 5 mm to 30 mm. Good quality pellets have a
density which varies between 600 kg/m3 and 750 kg/m3, with a moisture content
which varies from 5% to 8% by weight
We advice 6 mm pellets to be used.
The poorer the quality of the fuel, the more frequently will
intervention be necessary for cleaning the internal parts, such
as the grate and the combustion chamber.

4. BOILER PIPE INSTALLATION
•Horizantal chimney's duct and vertical chimney's pipe connections are very
important, therefore, it must be done carefully. Warranty of the smoke pipe
connection should be made accordingly.
•The minimum safety opening surface sections should be 15%. Slope in the
horizontal section of the pipe should be 3-5%. (3-5 cm per meter). The horizantal
chimney's duct should not be longer than 2 m.
•The stove chimney pipe outer diameter is 100 mm.
•Horizantal chimney's duct and vertical chimney's pipe should be made of durable
materials for heat, corrosion and condensation.
•Please take care of flue pipe standart sizes, the problems in case of using
nonstandard sizes will not be under our responsibility.
4.1 BOILER AND CHIMNEY WITH INSTRUCTIONS
•The main cause of the chimney fire;
oImproper selection or pipe that dust is flammable fuel. In the event of
appropriate conditions can cause fires ignite in the channels.
oWays of avoiding them; that the chimney should be cleaned at least 2 times per
year, depending on the fuel quality.
oThat correct and appropriate chimney selection should be made. Ensuring that
the sealing and smoke in the chimney pipe and must be made in isolation.
•Fresh air intake area of the ducts that maintaining and cleaning the boiler is
installed.
•Surrounding the peak point of the roof of the chimney to the interference of the
obstacle (the ridge) from height must be at least 80 cm.
•Should chimney's pipe inner diameter is 100 mm.
•Chimney flue test should be performed before making connections. If the chimney
connections should be carried out after removal of the traction problem had this
problem in the chimney.

15
•The boiler pipe connected to the horizontal chimney’s duct must not be longer than
2 m. Boiler pipe elbow should be used only until the chimney. (Site selection for
boiler should be determined by the closest point where the chimney.)
•To avoid turbulence around the chimney flue without any obstructions (high
buildings, trees, etc.) Must be 10 meter away at least.
•The pellet boiler should be mounted as close to the chimney as possible (chimney
connection should be short).
•Chimney cap should be used to prevent the flow into the chimney flue
repercussions of windy weather and rain. Concrete blocks is affected by
temperature changes, concrete flat roof which is in direct contact with the air must
be absolutely isolated.
Boilers must be connected to a chimney duct which can move vertically
smoke outside the building or its flue pipe to the highest point of the
building.
Chimney connections, if that would be considered illegal in the first
combustion fumes can cause the wall to infiltrate the processing of these
leaks may leave traces. Leaked smoke and / or flames can cause burns or
fire because it can be very hot.

16
4.2 SUITABLE SHAPES OF CHIMNEY
The remaining portion of the chimney outside the home, it must be insulated. The
smoke in the event of an electrical failure of your boiler with a natural drive capable
threw out the chimney must be applied.
