Dear customer,
We thank you that you have bought a AGURO pellet stove, thus having shown your confidence in VIADRUS brand.
Your new stove was manufactured in a company that is a holder of ISO 9001:2000 certification.
Before installation and commissioning, please carefully acquaintance with the instruction manual for your new
pellet stove. It will help you to avoid possible problems incurred as a result of violation of guidance and instructions
specified in this manual, which can – under certain circumstances – lead to a damage of the stove. Save this
manual for searching other information in the future.
1 Pellet stove usage and advantages
The automatic AGURO pellet stove is also determined for permanent heating of dwelling and commercial premises.
Fuel is conveyed by means of an auger from the fuel reservoir into the burner bowl, whereas the fuel quantity is
automatically corrected in dependence on a required heating power. In case of the full fuel reservoir, depending on
the required temperature in the room, the stove can be operated during about 30 hours.
The stove is controlled with help of a control unit, which is integrated in the fuel reservoir cover. A user can choose
one of the working modes: “Heating” or "Auto" with the week programming.
The control unit regulates the kindling phase, the heating phase and cooling phase, and ensures by this safety
operation of the pellet stove. The display displays a working mode, in which the stove is occurred at the moment.
Eventual error messages are displayed on the display in a text form with specification of date and time.
2 Pellet stove technical description
It is a stove assembled from high quality steel plates. The stove furnace is equipped with a cast-iron burner bowl.
The pellet stove doors are equipped with a heat-resistant glass, and their structure allows opening in the horizontal
direction to the left. A part of the pellet stove is a removable ash-pan. The pellet stove surface is protected by heatresistant painting with the resistance up to 650°C (heating chamber) and 350°C (other steel-plate parts – a side
wall, a rear cover, a stove cover, etc.).

4.2 General instructions for placement and installation
Each pellet stove has to be implicitly placed and installed so that there were observed the conditions specified by
local regulations or national and European norms as amended, including their additions, as well as in accordance
with instructions specified in this instruction manual.
The pellet stoves are determined for installation in dry premises that are characterized by a valid norm as
unaggressive environment without any explosive are combustible gases.

Before installation of pellet stoves it is necessary to carry out revision of the breast, into which the stove has to be
connected, including design and assessment of the flue channel, which has to provide safety exhaust of flue gases
from the connected stove. Only one consumer can be connected to the flue channel.
At installation it is necessary to provide sufficient access for cleaning of the consumer, the flue gas ducting and the
chimney.
In interior where a pellet stove is placed, it is not recommended to place equipment for air exhausting (for example,
a fume hood), which could invoke backward draught and leakage of flue gases into a room. If anyhow this
equipment is placed in the interior, it is necessary to provide regulation of its draught and suction of combustion air
from an extern room (a cellar, a technical room, etc.). Only overpressure air conditioning can be used.
4.3 Rules for placement
The consumer has to be put up on a firm basement with a corresponding capacity, preferably on a concrete or
other inflammable plate. If the existing set doesn’t comply with this necessary condition, it is necessary to make
sufficient measures to satisfy this requirement.
In case of installation to the floor from a combustible material, it is necessary to place the consumer on an
insulating pad from an inflammable material, which overlapped the ground plan of the consumer by 800 mm in the
direction of radiation, 400 mm from remaining sides.
It is not allowed to put subjects from combustible materials on the consumer and on the distance less than the
safety distance (see the following table). In case of unknown stage of combustibility it is necessary to go from the
distance for the stage E (F).

4.4 Connection of the pellet stove to the chimney
Before commissioning the pellet stove, check and testing of the flue channel has to be
performed even before closing the flue channel by the sheathing of the heat-air chamber.
These activities may be only performed by a qualified person, for example, a chimney-sweeper
company. The result of checking has to be recorded into the revision report of the flue
channel.
With regard to low demand factor of installation of the pellet stove, a customer may install the
stove by himself/herself. However we recommend ordering this installation from a proper
trained specialized building company or a chimney-sweeper or a stove-fitter company.
Revision of the flue channels has to be car
ried out:
•
before commissioning the flue channel
•
after each building modification of the chimney
•
before a change or new installation of the consumer.
Revision has to be performed by a qualified person in the sphere of chimneys – by
engineering inspector of chimneys.
• Flue exhausting is ensured by means of a flue exhauster, which is a part of the pellet stove.
• The stove has to be connected to a separate chimney. It is not allowed to draw off flue gasses from other
equipment to this chimney.
• The chimney can be in classical design (a brickwork), or from stainless steel or from ceramics.
• Usual pipes or springy steel pipes for flue gas ducting can be used for connection to the chimney.
• All parts of the flue gas ducting up to the entrance to the chimney have to be gas-tight from the reason of
possible occurrence of overpressure in the output of flue gases.
• The pipe of the flue gas ducting mustn’t intervene to a free cross-section of the chimney.
• The stove complies with requirements for connection to chimneys designed for temperature of flue gases of
350 °C.
• The minimum required chimney draught is 10 Pa. Draught is influenced both by the length of the chimney, and
by the surface of the chimney, and by quality of its sealing. The minimum recommended length of the chimney
is 3,5 m from the place of falling-in the flue gas ducting to the chimney and a suitable minimum cross-section
is 150 x 150 cm.
• The outer diameter of the connecting mouthpiece for smoke gas is 80 x 1,5 mm.
• The flue gas ducting has to be made from tightened steel or stainless pipes. Two 90° elbow-pieces can be
used.
• In case of placement of the flue gas ducting on the outer side of the building, it has to be equipped with
thermal insulation.
• Flue gas ducts with sharp bends and a horizontal routing decrease chimney draught. The maximum horizontal
piece of the flue gas ducting is 2 m, under condition that the length of the flue gas ducting is at least 5 m.
• The flue gas ducting has to be accessible for checking and cleaning. It is necessary to provide possibility of
sweeping of the entire length of the chimney, and the chimney door has to be easily accessible.
• Check attentively whether the chimney is tight and that no leakage of flue gases occurs around the chimney
door and connection of the flue gas ducts.
• Flue gases are to be drawn through the flue gas ducting with the diameter of 150 mm connected to the neck of
the flue gas ducting of the stove, which is placed on the upper (rear) part of the stove.
4.5 Connection of central air supply
Connection of central air supply has to be realized in air-tight buildings, where the content
of oxygen in the room heated by the pellet stove can be decreased.
• Connect the hose to the suction neck for air on the rear wall (Ø 50 mm).
• The entrance of the air supply line has to be placed in outdoor space or in sufficiently vented room of the
building.
• At installation of the stove in a building with controlled ventilation of habitable premises, the entrance of air
supply mustn’t be placed in a room, which is connected to the associated ventilation system.
• In order to ensure sufficient air supply, the supply line mustn’t by longer than 3 m and mustn’t have too much
bends. The minimum diameter of the supply line is 50 mm.
• If the supply line enters into the outdoor space, it has to be bent by 90° in the down direction or has to be
ended in the dead air region.

5.1 Opening of the pellet stove door
The stove has two doors. The cast-iron door separates the heating chamber from other environment, and the
glassed one is decorative and completes the pellet stove design.
Be particular about sealing surfaces of the inner frame of the cast-iron door to ensure their easiest closing. The
cast-iron door can be opened with help of a handle; the decorative door can be opened by means of a clip and a
magnet (they are a part of delivery). Observe cleanness of the both doors.
The both doors always during stove operation have to be closed, otherwise the stove wouldn’t work
correctly and can be damaged!
If necessary, always open the cast-iron door slowly and carefully, in order to avoid sudden change of pressure in
the heating chamber and escape of smoke into the room.
5.2 Safety instructions
• At handling and unpacking, be careful and observe safety instructions!
• In case that there is a danger of occurrence of flammable gases for the temporary period in the room
with an installed stove (for example, during gluing of linoleum, at painting work, etc.), the pellet stove
has to be put out of operation even before occurrence of this danger!
• During burning of the surface painting of the stove at the first firing-up, it is necessary to ventilate all
the time and bring sufficient quantity of fresh air into the room!
• At operation it is necessary to provide sufficient supply of combustion air and safety withdrawal of
flue gases!
• The both doors have to be always closed!
• The pellet stove may only be operated by a capable adult person!
• Ensure that children, persons with mental disabilities and domestic animals cannot get to the space of
the furnace itself or very hot parts during operation of the stove (doors, glass, side covers, the furnace
cover, etc.) – danger of burning and possible life danger!
• For the entire period of operation, fire in the stove has to be regularly checked!
• In case of simultaneous operation of other heating device in the same room, it is necessary to ensure
sufficient ventilation!
• Don’t touch the outer surfaces of the stove – danger of burning and possible life danger, except of
control and regulating elements!
• Never extinguish fire in the pellet stove by water!
• Ash from the ash-pan has to be removed carefully and with using of protective equipment, and only
when the pellet stove is out of operation!
