General Information
WARNING! To avoid the re hazard, the device must be installed in accordance with the applicable
standards and technical regulations, which are mentioned in the further part of the manual.
The installation must be performed by a professional and qualied sta.
The device complies with the EN 13240 standard and has the CE certicate.
Freestanding stoves are designed to burn wood from deciduous trees. They are used for heating
houses and spaces, in which they are installed. They can be used as an additional source of heat
energy. Before installation, read the attached user manual. After unpacking check the completeness
of the device and the operation of its moving parts: primary air control mechanism (at the door), door
functioning mechanism (hinges, handle).
The device has to be installed in accordance with the applicable standards of the construction law.
Installation of the stove should be performed by the installer. The manufacturer is not liable in the
case when the installation is contrary to the applicable regulations and standards (construction
regulations, national and local regulations), which must be followed.
The stove has to be set at a safe distance from any ammable products. There may be a need to
secure the wall and the materials surrounding the stove. The free-standing stove should be set on
the non-ammable surface with sucient capacity. If the ground is not adapted for supporting the
weight of the stove, the appropriate undertakings should be performed to improve the bearing capa-
city (e.g. the use of plates spreading the load
on a greater surface).

Construction material: Cast iron/Steel
Sto e elements made of steel designed for operation at elevated temperatures, steel elements cut by
laser, and then bent at the bending machines CNC and rolled. The body is welded using a welding
robot, in the shield of noble gas, what provides good quality of welds.

furnace, contributes to the improvement of combustion parameters, inuences the purity of com-
bustion, burning harmful gases additionally limits the formation of soot on the glass of the stove

Spare parts
If, after many years, it is necessary to replace some parts, contact with the seller or with any repre-
sentative of our company. When ordering spare parts, you should provide information from the
nameplate located on the back of the warranty card, which should be kept even after the expiration
of guarantee. With these data and our factory documentation, the seller will be able to provide all
spare parts in a short time.
Chimney
The standard stove has the upper discharge of ue gases, with an optional rear discharge of gases,
after switching the connector of the exhaust. The free-standing stove should be connected to the
chimney (ue). Specication of the minimal chimney draft for the nominal heat output [Pa]: The size
of the chimney draft should be: - a minimum string - 6 ± 1 Pa; - average, recommended - 12 ± 2 Pa; -
maximal - 15 ± 2 Pa. The chimney must be tight, and its walls smooth, before the connection it should
be cleaned of soot and all contamination. The connection between the chimney and the device
must be tight and made of non-combustible materials, secured against oxidation (e.g. enamel steel
chimney pipe). If the chimney produced a weak string, we should consider new cables
It is also important for the chimney not to produce excessive strings, so we should install the string
stabilizer in the chimney. The alternative is also the special ending of the chimney regulating the
power of the thrust. The control of the chimney should be ordered to the chimney master, and the
potential modications can be made by an authorised company, so that the requirements are met.
Connection to the chimney ducts should be performed in accordance with the standard.
The minimal eective height of ue chimney is 4-6mb. The length of connection of the device to the
chimney should not exceed 1⁄4 of the total height of the chimney.

Ventilation in the room, where the stove is installed
The stove for its operation uses air, therefore, it is required to provide the adequate ventilation of
the room, where the device is installed. Inlet grills of the ventilation system in the room should be
protected against self-closing.

Safety Local Regulations Must Apply
The stove should be set on the non-ammable ground with a thickness of at least 30 mm. Easily
ammable oor in front of the doors of the heater should be protected with a belt of non-combusti-
ble material with the width of at least 30cm.
Flue outlet system connection elements should be distant at least 60 cm from ammable expo-
sed structural parts of the building and from non-exposed at least 20 cm.
Minimum distance from combustible materials: sides of the device and back - 20 cm,
from the door - 80 cm; (as there is no other information on the device`s name plate).
During all activities related to the maintenance and exploitation of the furnace one should remember
that its steel elements can have high temperature, and therefore, for the operation one should use
protective gloves. During the exploitation and use of the furnace, one should follow the rules, which
provide basic safety conditions:
- Familiarize yourself with the user manual of the heater and strictly observe its provisions;
- The oven should be installed and started by the installer according to the safety rules
- Do not leave things sensitive to temperature near the stove glass, do not extinguish re with water,
do not exploit the oven with a broken glass, near the oven there can be found ammable elements;
- Items made of inammable materials must be at the distance of at least 1,5 m from the furnace;
- Do not allow children in the vicinity of the furnace;
- All repairs should be entrusted to the installer and use only the spare parts of the furnace manufac-
turer;
- Any changes of the structure, installation rules, use rules, are not allowed without the written
permission of the manufacturer;
Fuel
A free-standing stove is designed for burning wood of deciduous trees (oak, hornbeam, ash, beech,
etc.) with a moisture content lower than 20% (seasoned wood in suitable conditions for at least 2
years).
It is acceptable to use wood briquettes or lignite. It is unacceptable to burn wet wood (intensive
soiling of the stove and emission of soot, as well as reduction of energy eciency).
It is forbidden to use any other fuel, among others, coal, coniferous wood, tropical wood and all liquid
fuel. It is forbidden to burn any types of garbage and wood waste. Burning the stove with unaccep-
table materials can cause its damage and threat to the life and health of users (poisonous fumes of
chemical substances).
