Construction: stove is made of 3mm thick. The combustion chamber 5 is lined with AKUCERAM on
the bottom, side walls and back wall. The design allows the exhaust gas to be led out through the top
or rear wall of the furnace. The air inlet 7 has a diameter of 100mm, flue 1 150mm. The freestanding
stove is adapted to work with a hot air distribution system (DGP) 18,19. The front of the stove consists
of steel door made of special profile 9 and profiled sheet metal, heat resistance glass pane 15, and
handle 16. The door is bolted to the slats attached to the stove body.
A description of the action:
Air enters the furnace throughy the inlet opening 7. There are two air intake system in the
interior – primary and secondary. Adjustment of the amount of incoming primary air takes place via
the right control lever located on the front of the stove under the door 13. Then the air flows around
the ash pan 8 and through the grate 6 it enters the combustion chamber 5.
The amount of secondary air is regulated by the left lever 12 on the front of the stove. The air is
directed to the combustion chamber 4 to burn the exhaust gases, which improves thermal efficiency
and reduces the amount of pollutants. To adjust the amount of air, pull the lever out to open the air
supply and push it in to close the air supply.
The stove Is also equipped with an air curtain 17 to help maintain the clean glass. There is a
special ceramic plate called a deflector above the combustion chamber 2, which enhances heat
exchange. During combustion, hot gases flow around the deflector and then through the flue 1 and
the pipes to the chimney. The stove environment is heated in two ways – the air surrounding the
stove is heated (convection) and escapes through the ventilation slots in the furnace housing. In
addition, the heat radiates directly from all hot parts of the stove.
2. TRANSPORT, , ASSEMBLY AND INSTALLATION OF THE
FREESTANDING STOVE

2.3. Recommendations concerning the floor:

www.karles.se
11
•before installing the stove, check the load-bearing capacity of the floor (to make sure that it
is sufficient to bear the weight of a given type of appliance);
•the floor must be made of non-flammable material with a minimum thickness of 30 cm; a
safety area of least 60 cm must be ensured in front of the stove door, and of at least 30 cm
from the edges of the door.
Rys. 8 Ground and distance recommendations.
2.4. Chimney duct
The stove must be appropriately selected to match the cross section of the combustion gas duct (flue
pipe) and the height of the flue.
The cross-sectional area of the flue and of the combustion gas duct is calculated in accordance with
the following formula:
where:
F – cross-sectional area of the flue and of the combustion gas duct [m2];
Q – rated thermal input [kW];
h – the height of the chimney [m].
In accordance with the applicable provisions of law, the flue may not be smaller than 14x14cm or its
diameter must be 15cm. Stove with a higher thermal input require a flue with a larger cross section.
The cross section also depends on the height of the chimney.
The stove should be connected to the combustion gas duct or the vertical duct in accordance with
the applicable national standards.

www.karles.se
12
The chimney draught should be as follows:
- minimum draught – 6  2 Pa;
- MEDIUM, RECOMMENDED DRAUGHT – 12  2 Pa;
- maximum draught – 15  2 Pa.
NOTE:
To ensure the correct functioning of the stove, there must be a correct chimney draught in the
connector of the flue pipe:
• the stove will not function properly if the chimney draught is not sufficient, resulting in excessive
soot deposits on the glass and in combustion gas ducts and reducing the total thermal power of
the stove (due to which combustion gases may escape to the room);
• if the draught is too strong, the burning process may be too intense, causing high consumption of
fuel and resulting in permanent damage of the stove.
The chimney should be regularly inspected by a chimney sweep company.
2.5. Connection of the chimney ducts:
•before installing the stove, the chimney ducts and its technical parameters and conditio must
be inspected and approved by a chimney expert;
•the stove may be only installed after the flue pipe has been inspected and approved by a
chimney expert.
The chimney duct must satisfy the applicable national or European standards.
The stove must be mounted and connected to the chimney in accordance with the supplied
Operation and Installation Manual (together with deflector plates - if they are to be used, and the
insulation of the flue pipe).
The manufacturer does not recommend the assembly and installation of the appliance by the user on
his or her own. To make sure that the stove is installed and put to use in a correct and safe manner
and to satisfy the guarantee conditions, the user should have the appliance installed and put to use
by a qualified installer or an installation company. The installer is required to confirm in the guarantee
card (signature and stamp) that the fireplace has been installed in accordance with good building
practices and the applicable legal provisions. If the above-mentioned activities are not performed, it
will invalidate the guarantee.
2.6 The combustion gas outlet system should have the following features:
•the cross section of the flue pipe may not be smaller than the cross section of the chimney
duct and it may not become narrow towards the chimney (between the flue pipe and the
chimney, the diameter can be increased through the use of mounting adapters);
•the path of the combustion gas duct should be as short and straight as possible (bends
increase flow resistance and facilitate the accumulation of condensed moisture);
•it is forbidden to connect the stove to the same chimney duct with another heating device;
•the stove should be connected to its own chimney duct ;
•the combustion gas duct may not have more than two inclinations of 45° when its length
does not exceed 5 m and of 20° when it is more than 5 m long;
•the combustion gas duct must be made from non-combustible materials and it must be
thermally insulated;
•the insulation of the flue pipe must ensure fire resistance for at least 60 minutes;
•the flue exit should be followed by a straight pipe with a minimum length twice as long as the

www.karles.se
13
diameter of the stove flue;
•the connector must be leak-proof;
•the end of the chimney should ensure a trouble-free outlet for combustion gases and it
should be placed at least 60 cm above the highest point of the roof
•the connectors must be made from stainless, heat-resistant steel 1.4401 (316) or fireplace
steel, painted with a special paint. The metal sheet must have an appropriate thickness
(heat-resistant and stainless steel must be 1mm thick, fireplace steel - 2mm) and be resistant
to high temperature, the acidity of combustion gases and condensed moisture.

2.7. Ventilation of the stove:
•it is necessary to bring in fresh air from the outside by unsealing the windows so that there
is a constant air supply. Too little fresh air from outside can cause bad combustion
(production of carbon monoxide), and in the worst case, with tightly closed windows, there
may be backflow of air with carbon monoxide through the ventilation ducts and there may
be a risk of poisoning by exhaust fumes;
•the design of the stove allows the supply of fresh air from the outside (air is supplied
throught a pipe with a diameter of 100mm). The pipe can lead out of the wall behind the
back of the stove or, after unscrewing the base, from the floor. It is also possible to supply air
directly from the room in which the stove is located, providing adequate ventilation,
protected against automatic closing of the air supply.
•it is estimated that about 8m3 of air is required for burning 1kg of wood;
in the case of using a system of distributing air to other rooms, it is essential to ensure the
return of cooled air to the room where the stove is installed so that the air can circulate
freely (otherwise, the work cycle of the stove may become disrupted, which will hinder the
distribution of warm air);
•when determining the location and assembly of the device, pay attention to the principles of
proper air circulation and its balance in the room;
•in the room where the stove is installed, ventilation must be provided;
•to ensure adequate convection space (stove cooling, air heating), the stove should be placed

www.karles.se
14
at least 80 cm away from materials that could be distorted or damaged by high temperature
(furniture, paneling, wallpaper, etc.).
Fig. 10. The scheme of air connecting
2.8. Installation of the stove
The appliance must be installed in accordance with the applicable pro-visions of the building law.
The stove must be installed and assembled by qualified specialists.
Fig. 11. Safe zone for flammable materials
•the stove must be placed at a safe distance from any flammable materials (the walls or other
surfaces surrounding the stove may have to be secured);
•the space in front of the furnace must be protected against spark that may fall out of the
furnace while adding fuel. The minimum safe area is 60 cm in front of the stove and 30 cm to
the sides from the edge of the door. Surface can be protected with natural stone, floor tiles or
a dedicated glass base.
•it is forbidden to install the stove in a bedroom, bathroom or in a room with another heating
device without its own air intake;
•the stove is a uniform structure and does not require any additional supports;
•height adjustment (leveling) of the stove is possible thanks to the legs (you can unscrew up to

www.karles.se
15
20mm);
•if it is necessary to raise the stove above the adjustment of the feet, make a brick base and
place the device on it (do not remove the feet needed for leveling);
•lack of proper leveling prevents proper operation of the door (it will not close properly);
2.9. Connecting the hot air distribution.
The hot air distribution system allows the convective heat generated by the furnace to be
used to heat other rooms. Depending on the power of the device and building conditions, different
solutions are used. Choosing the right one should be entrusted to a person or company with
experience in this field. A simple gravity system is perfect for small single-story houses. On larger
surfaces, sometimes it is necessary to use blowers forcing air circulation.
Freestanding stoves allow you to connect the hot air distribution system to the stove in too
ways: from the top (LUPO, CANE, LYNX) or from the bottom (LUPO, CANE). When installing from the
top, it is necessary to cut out fragments of the rear cover in the places marked in the drawing. We
gain uninterrupted airflow. When installing the pipes from the bottom, a blower to extract the heated
air is required in the system. Montage of the tubes is takes place by to a special set of fittings with a
diameter of 100mm. Cutouts allow with assembly to thin or thick sheet metal.

On a properly installed connector install pipes to discharge heated air to other rooms. For the proper
operation of the system, it is necessary to ensure the return of cool air to the room where the stove is
located.
3. START-UP
After the stove has been mounted and connected to the chimney, the first start-up of the stove must
be performed by an installer or a qualified service technician.
As part of the start-up procedure, the installer should show the User how to operate the stove
correctly.
The installer is obliged to refuse to put the stove into use if he or she finds any assembly-related
irregularities which make it unsafe to use.
A correctly performed start-up should be confirmed in writing in the guarantee card.
3.1. Getting ready for the start-up
Before lighting the stove for the first time, it is necessary:
•to remove any labels, paper stickers and accessories from the body of the stove or hearth to
eliminate the risk of fire; the same applies to transport safety devices;
•to check if the deflectors, ceramic fittings are mounted correctly and were not dislodged
from their correct position during installation (any discovered mounting errors must be
corrected). Non-removal of such errors may hinder proper functioning of the stove. In the
case of stove with multi-pane glass doors, it should be checked if particular glass panes did
not become loose during transport or use;
•to check the operation of:
−mechanism regulating the air inflow into the combustion chamber;
−front door closing mechanism (hinges. handle);
•to check the correctness of the installation in terms of the following safety related issues:
−is the stove levelled;
−is a ventilation system properly installed;
−is the connection to the chimney sealed properly;
−has the stove housing been built correctly.

www.karles.se

3.2. Lighting the stove
Before lighting the stove, please do the following:
•arrange a stack of firewood in the hearth, starting with larger pieces of wood, followed by
medium sized pieces of wood and then by small chips of wood for fire lighting – light it with a
match;
•set the primary air regulator in the fully open position;
•after lighting the fire, the door of the stove must be closed;
•when the fuel is properly ignited, use the air regulator to set calm, rather muffed combustion
(this causes only a small part of the primary air to be fed under the grate of the stove;
secondary air damper to the maximum – more air is supplied to the air curtain system, which
protects the glass against blackening, and to the gas afterburning system at the front of the
stove; opening the air throttle to 100% - maximally towards itself, causes very intensive fuel
combustion);
•it is recommended, at the final stage of burning, to open the door and move the remaining
members onto the grate, using a poker, so that all fuel is used up;
NOTE:
Because of too big amount of air is fed under the grate and to the after burning system, too much
fuel in the combustion chamber causes the production of a large amount of wood gas and the glass
pane may become temporarily covered with soot.
When the mechanism is pressing the throttle to the maximum, it will completely cut off the inflow
of air to the combustion chamber and the fire will be gradually put out.
If the grate needs to be unclogged, stir accumulated ash with a poker or the lever of the grate (if
the stove is equipped with a movable grate).
During the first hours of using the stove, it is recommended to load the stove with a small amount
of fuel, i.e. up to 50% of the normal load.
When the stove is lit for the first time, water may condense on the internal walls of the
combustion chamber. This phenomenon is normal and is caused by the condensation of water
vapour contained in combustion gases. It should disappear after the combustion chamber has
heated up.
If combustion gases escape from the fireplace chamber, the position of the combustion gas throttle
should be adjusted and the chimney draught should be increased.
Before the next lighting, clean the hearth from remaining ash.
fIG. 16. Throttle operation: pressed - air supply closed, pulled out - air supply open.
4. USE
The surface of the stove is covered with a special heat-resistance paint. After lighting the stove, this
paint initially becomes soft (care must be taken not to scratch it then) and then hardens. Due to this
process, an un-pleasant smell is produced when the stove is lit for the first few times. It is

recommended to make sure that the room is well aired during that time. If pets or birds are kept in
the room, they should be temporarily moved to another place. In the initial stage of using the stove
(for about 2 weeks), the manufacturer recommends maintaining a small flame by burning a smaller
quantity of fuel at a lower temperature. This method of lighting the stove is intended to prevent
cracks in the ceramic lining, to avoid deformation of the stove structure or damage to the protective
(paint) layer of the stove.
4.1. Types of fuel
Considering the design of our appliances, the most suitable type of fuel is the deciduous hardwood,
including: oak, hornbeam, ash, beech, birch. In particular, we recommend using birch wood.
The best fuel is wood which has been seasoned (for at least two years in a well-ventilated and dry
place), cut and chopped into logs. We advise against using the wood of coniferous trees. Freshly cut
or damp wood is not a good fuel because it has low calorific value. The burning of insufficiently dried
wood may result in increased deposits of creosote in the combustion gas ducts, which may cause
overheating the stove and the glass panel to break.
NOTE:
It is forbidden to burn waste fuel, liquid fuels and other types of fuel not recommended by the
manufacturer of the stove.
It is strictly forbidden to use the following as fuel for the stove: bituminous coal, the wood of tropical
trees, all types of products containing chemical compounds such as petrol, alcohol, naphthalene, oil,
waste and laminated panels containing adhesives.
4.2. Refuelling:
•fuel should be added when flames disappear over the layer of embers in the hearth; it is best
to heap embers into a pyramid-like shape onto the grate (from both sides, to ensure a
sufficient flow of air from underneath the grate for flames to appear) and then add slivers of
wood;
•embers should not be heaped over the grate in an even layer because it would significantly
reduce the flow of air from under the grate and result in a build-up of gas in the hearth
chamber and in the whole stove, which might lead to an explosion;
•wooden logs in the combustion chamber should be arranged in parallel to the plane of the
door;
•before loading the hearth with a new portion of wood, remove ash from the grate and empty
the ash pan if necessary.
4.3. Preventing the escape of combustion gases
To prevent the escape of combustion gases from the stove to the room during the opening of
the door, it is recommended to:
•set the primary air regulator in the fully open position for about 10 seconds before opening
the door (the lever of the throttle maximally extended);
•open the damper valve of the combustion gas throttle in the flue (if such a valve is installed in
a given stove);
•move the door slightly partly open, wait a few seconds (until combustion gases disperse) and
then slowly open the door of the stove;
•exercise caution when opening the door and after opening it because burning pieces of wood
may fall from the hearth;
•after adding an appropriate quantity of fuel, close the door of the hearth;
•when the fuel is well alight, set the air regulator in its original position;
