INSTRUCTIONS FOR CONNECTING, OPERATION, AND MAINTENANCE OF THE STOVE
Heating devices (in this manual they are called “stoves") by Company Biodom (in this manual titled
Biodom) are assembled and tested in accordance with the safety and applicable measures, and
regulations of the European Community.
This manual is intended for users of the stoves, contractors who install the stoves, operators and
workers for stove maintenance that is shown on the front page of the manual.
If you do not understand something in this manual, please contact our professional services or an
authorized service center. In doing so, always specify the number of the chapter where there is some
ambiguity.
Printing, translation and reproduction, even in part, of this manual is subject to licensing by Biodom,
which means that Biodom must approve these actions. Technical information, figures, and
specifications in this manual must not be given to a third party.
WARNING:
IMPORTANT: Connecting the appliance to the electrical installation must be carried out by qualified
and authorized persons in accordance with applicable regulations.
This appliance is not intended for use by persons (including children) with reduced physical, motor,
and mental capabilities, or to persons with a limited knowledge and experience in the absence of
the person responsible for their safety or care.
DOUBLE COMBUSTION SYSTEM
The flame obtained by proper combustion of the pellet in the stove emits the same amount of carbon
dioxide (CO2), which would be freed as a result of the natural decay of wood.
The amount of carbon dioxide (CO2) obtained through combustion or decomposition of plant mass
corresponds to the amount of carbon dioxide (CO2) which the plant mass is able to obtain from the
environment and to transform it into air and carbon of the plants during its entire lifetime.
The use of non-renewable fossil fuels (coal, oil, gas), contrary to what happens with the wood, releases
into the atmosphere huge amounts of carbon dioxide (CO2), that have been gathering up for millions
of years, creating a greenhouse effect. The use of wood as fuel is therefore perfectly balanced with the
environment, because the wood as a renewable fuel is in ecological harmony with nature.
Using the principle of clean combustion, we fully achieve these objectives, and so Biodom has directed
its development and all activities towards fulfilling this goal.
What do we consider clean combustion and how does it work?
Controlling and adjusting the primary air and injecting the secondary air causes secondary combustion,
or the so-called post-combustion, which provides a secondary flame that is by its nature lighter and
stronger than the primary flame. The addition of a new oxygen (inserted through the air) allows further
combustion of gases that are not completely burned. This significantly increases the thermal efficiency
and reduces harmful emissions of carbon monoxide (CO), because the incomplete combustion is
minimized. These are the basic characteristics of these stoves and other products of Biodom.

WARNINGS
ATTENTION
DISCARD ALL PACKAGING OUT OF REACH OF CHILDREN. DANGER OF SUFFOCATION WITH BAG, FOIL,
POLYSTYRENE ETC.
ATTENTION
Smoke gas discharge MUST NOT BE CONNECTED TO:
•Flue pipe, used by other combustion devices (boilers, stoves, fireplaces etc.);
•Air extraction systems (hoods, air extraction fans etc.).
ATTENTION
Installation of draught closing valves is prohibited!
Flue connection Ø 80 mm from pellet boiler to flue pipe should be:
no more than 12 m long (in case of longer connection, dimension of connection pipe must increase to
Ø 130 mm);
each 90° joint requires a 1 m shorter flue connection;
each joint must be fitted with doors for cleaning;
connections between pipes must be sealed
ATTENTION
If there is too much resistance in extraction system (many joints, improper end fitting, bottlenecks
etc.), extraction of smoke gases is not provided for. Therefore, connection pipes and joints must be
increased to a greater dimension – Ø 130 mm. If the flue does not ensure appropriate extraction of
smoke gases, it can also come do improper operation and, consequently, to alarm from boiler
BIODOM. It is advisable that the flue is inspected by an expert before installing boiler BIODOM.
ATTENTION
Never turn off the boiler by pulling the electrical cable from the socket, while fire is still burning in the
boiler. This could damage the boiler and seriously jeopardize its functioning

Biodom C15 | instructions for use, maintenance and installation | February 2019
13
ATTENTION
Extraction of smoke gases must be earthed in accordance with regulations in force. (Earthing
connection is required by law). Earthing must be independent of combustion unit.
ATTENTION
When the boiler installation is finished, it is mandatory to perform measurements of smoke gases
discharge.
ATTENTION
The pellet boiler operates by creating negative pressure in the combustion chamber. Therefore, ensure
that the extraction of smoke gases is thermally sealed.
Upon first start-up (minimum operation of boiler – 1 hour), paint evaporates fumes, which have
unpleasant odour. Therefore, ventilate the room afterwards.
ATTENTION
DURING PELLET BOILER OPERATION, CHILDREN ARE PROHIBITED TO COME NEAR OR PLAY WITH IT!
ATTENTION
Be careful that the sealant rope under the edge of combustion chamber is not damaged. If the
sealant rope is damaged, contact an authorized service centre.
ATTENTION
Ensure that the pellet boiler and ashes in it are cool before cleaning.
ATTENTION
In the event of fire in the flue pipe, all persons and animals must leave the area, then immediately
disconnect power supply from the main switch or socket (if it is possible without risk) and call the fire
department.
