Structure:
The stove is made of 3 mm thick P265GH boiler steel. The interior of the stove is lined with a heat accumulat-
ing ceramic lining 7. The construction of the stove enables the combustion gases to escape through the upper
or rear wall. The air inlet 10 has a diameter of 123 mm, ue 1has a diameter of 150 mm. The front of the stove
consists of steel door made of special prole and proled metal sheet, heat resistant glass pane 13, and a han-
dle 12. The door is screwed to the bars which are fastened to the body of the stove.
Description of the operation:
The air enters the furnace through the inlet 10. Inside, there are two air intake systems - primary and
secondary. The amount of incoming primary air is controlled via the lower intake throttle located on the front
of the stove under the door 14. Then, the air ows around the ash pan 9, and through the grate 8it enters the
combustion chamber 7. The amount of the secondary air is unregulated. The air is directed to the upper part
of the combustion chamber 6. The amount of the air is regulated by moving the lever to the left to open the air
supply, and the right to close the air supply.
The stove is also equipped with an air curtain 11 to help maintain the clean glass. Above the combustion cham-
ber, there is a special ceramic plate called deector 5, which enhance the thermal exchange. During burning, hot
gases oat over the deectors and then through the ue 1and the duct they go to the chimney. The surrounding
around the stove is heated in two ways - the air surrounding the stove is heated (convection) and exits through
the ventilation slots in the stove encasing. In addition, the heat radiates directly from all hot parts of the stove.
2. TRANSPORT, ASSEMBLY AND INSTALLATION OF THE STOVE
The device is compliant with the PN-EN 13229:2002 standard and has a CE certicate.

The stove must be installed by a qualied person or company and commissioning checks must be per-
formed by a master chimney sweep and a re prevention specialist.
The installation of the stove should be performed in the following order:
▪prepare the place where the stove will stand, check carrying capacity of the ground;
▪connection of the stove to the chimney and make ventilation;
▪putting the stove into use and observing its functioning for the purpose of detecting defects and anoma-
lies (for about 2 weeks);
2.1. Transport and handling:
▪the stove is delivered as an assembled unit, fastened to a palette and wrapped in stretch foil;
▪the stove should be transported in a vertical position;
▪after unpacking, check the stove for any transport related damage;
▪unpack the stove in the vicinity of the installation site; exercise caution when moving the stove (preferably

6
on a cart, paying special attention to the door and glass);
▪the packaging materials of the stove are not toxic or harmful and should be recycled or stored by the User;
▪to facilitate the assembly of the stove in hard-to-reach places, the ceramic lining (shielding the hearth) can
be removed; after the assembly, every element should be correctly placed in its intended location.
2.2. Assembly
The air inlet pipe can be connected through the lower click door of the stove.
The design of the stove allows 2 dierent congurations. The ue can be on the side or top wall and the side

2.3. Recommendations concerning the oor:
▪before installing the stove, check the load-bearing capacity of the oor (to make sure that it is sucient to
bear the weight of a given type of appliance);
▪the oor must be made of non-ammable 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.
Fig. 5 Recommendations concerning the oor and surrounding

9
2.4. Chimney duct
The stove must be appropriately selected to match the cross section of the combustion gas duct (ue pipe)
and the height of the ue.
The cross-sectional area of the ue and of the combustion gas duct is calculated in accordance with the follow-
ing formula:
where:
F – cross-sectional area of the ue 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 ue may not be smaller than 14x14cm or its diameter
must be 15cm. Stoves with a higher thermal input require a ue 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.
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 ue pipe:
▪the stove will not function properly if the chimney draught is not sucient, 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 to the chimney duct:
▪before installing the stove, the chimney ducts and its technical parameters and condition must be inspect-
ed and approved by a chimney expert;
▪the stove may be only installed after the ue 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 In-
stallation Manual (together with the deector plates - if they are to be used, and the insulation of the ue 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 qualied installer or an
installation company. The installer is required to conrm in the guarantee card (signature and stamp) that the
stove 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.

10
2.6. The combustion gas outlet system should have the following fea-
tures:
▪the cross section of the ue pipe may not be smaller than the cross section of the chimney duct and it may
not become narrow towards the chimney (between the ue 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 ow
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 ue pipe must ensure re resistance for at least 60 minutes;
▪the ue exit should be followed by a straight pipe with a minimum length twice as long as the diameter
of the stove ue;
▪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 replace steel, painted
with a special paint. The metal sheet must have an appropriate thickness (heat-resistant and stainless steel
must be 1mm thick, replace 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 fresh air from the outside through unsealing the windows so that
there is a constant supply of the air. Too small amount of fresh air from the outside can cause
poor combustion (production of carbon monoxide), and in the worst case, with tightly closed
windows, the air can escape with carbon monoxide through the ventilation ducts and there is
a risk of smoke poisoning;
▪the construction of the stove enables the supply of the fresh air (the air is supplied by throttles) directly
from the room where the furnace is located, while ensuring adequate ventilation against automatic closing
of the air supply from the outside;
▪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 choosing the site for the appliance and during its installation, attention should be paid to ensuring
the correct circulation of air and a proper balance between air ow in the room;
▪ventilation must be provided in the room where the stove is installed;
▪to ensure adequate convection space (stove cooling, air heating), the stove should be placed at least 80cm
from materials that could be deformed or damaged by high temperature (furniture, paneling, wallpaper,
etc.).
ATTENTION!
▪the best way to ensure the right amount of air to the stove is to bring it through a special air supply duct
directly from the outside of the building located under the oor;
▪it is also possible to connect the stove to the inlet located in the wall of the building using reproof pipes;
▪when using close inlet distances to the insert, we recommend turning the pipe under the stove before con-
necting it to the air intake, so that the cold air has time to heat up before entering the combustion chamber;
▪care must be taken to ensure that cold air from the outside does not lead to condensation of warmer air on
and in the air intake pipe or the furnace, which may cause an increase in moisture in the furnace chamber.
This can lead to rapid corrosion of the stove;
▪to prevent this phenomenon, we can connect the stove at a slight slope to the outside, insulate the air sup-
ply pipe and use an additional damper closing the air intake when the replace insert is not in use;
▪in the case of too strong draft that does not allow for combustion regulation, an additional damper should
be used to additionally protect the replace insert against the inow of too much air into the combustion
chamber when the stove is used or completely close the air supply when it is not in use;
Failure to meet the above conditions may lead to improper operation of the stove, its corrosion or problems
with air regulation that are not subject to complaint.

12
2.8. Installation of the stove
The appliance must be installed in accordance with the applicable provisions of the building law.
The stove must be installed and assembled by qualied specialists.
To ensure the correct installation:
▪the stove must be placed at a safe distance from any ammable materials (the walls or other surfaces
surrounding the stove may have to be secured);
▪the space in front of the stove must be protected against sparks that may fall out of the furnace during add-
ing fuel. The minimum safe area is 60cm in front of the stove and 30cm from the edge of the door. Surfaces
can be protected with natural stone, oor 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;
▪it is not permitted to integrate the stove with an air recuperation system;
▪the stove is a standalone device and does not require any additional supports;
▪the stove is equipped with regulated feet for adjusting the height (levelling) of it (with an adjustment range
of up to 20 cm);
▪if the stove has to be raised above the adjustment range of the feet, make a brick base and place the stove
on it (do not remove the feet as they are needed for levelling purposes);
▪incorrect levelling of the stove will hinder the functioning of the door (it will not close properly);
3. START-UP
After the stove has been mounted and connected to the chimney, the rst start-up of the stove must
be performed by an installer or a qualied 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 nds any assembly-related irregularities which make it unsafe to use. A correctly performed
start-up should be conrmed in writing in the guarantee card.
Fig. 7 Safe area for ammable materials

13
3.1. Getting ready for the start-up
Before lighting the stove for the rst 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 re; the same applies to transport safety devices;
▪to check if the deector/s, ceramic ttings 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 stoves 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 inow into the combustion chamber (cold air inow throttle);
• front door closing mechanism (hinges, handle);
3.2. Lighting the stove
Before lighting the stove, please do the following:
▪arrange a stack of rewood in the hearth, starting with larger pieces of wood, followed by medium-sized
pieces of wood and then by small chips of wood for re lighting – light it with a match;
▪set the primary air regulator in the fully open position and the secondary one in the minimum;
▪after lighting the re, the door of the stove must be closed;
▪when the fuel is burning properly, adjust the burning process with air regulators to ensure a steady and
calm rate of burning (this causes only a small portion of the primary air to be fed under the oven grate;
secondary air throttle to max - more air is fed into the air curtain system, protecting the glass from sooting
and to the gas afterburning system in front of the cartridge; opening the air damper at 100% - maximally
to each other, causes very intensive combustion of fuel);
▪it is recommended, at the nal stage of burning, to open the door and move the remaining embers onto
the grate, using a poker, so that all fuel is used up;
▪test the functioning of other components of the installation (when the re is lit for the rst time).
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 moved to its rightmost position, it will completely cut o the inow of air
to the combustion chamber and the re will be gradually put out.
If the grate needs to be unclogged, stir accumulated ash with a poker or the lever of the grate.
During the rst 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 rst 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.
JIf combustion gases escape from the stove 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.
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 unpleasant smell is produced when the stove is lit for the rst 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 recom-
mends maintaining a small ame 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

14
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 caloric value. The burning of insuciently 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 recom-
mended 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. Refueling:
▪fuel should be added when ames 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 sucient ow of air from
underneath the grate for ames to appear) and then add slivers of wood;
▪embers should not be heaped over the grate in an even layer because it would signicantly reduce the ow
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 (lever
moved to its leftmost position);
▪move the door slightly partly open, wait a few seconds (until combustion gases disperse) and then slowly
Fig. 8 Throttle operation - moved to the right - air supply closed, moved to the left - air supply open.

15
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;
▪the optimum amount of fuel for 6,5 kW stove is 1,9 kg/h.
NOTE:
Take care not to overload the stove with fuel. Overloading may cause permanent
damage to its structure.
4.4. Keeping the glass pane clean
The cleanliness of the glass pane depends on using appropriate fuel, as well as on:
▪supplying a sucient quantity of air for the burning process;
▪optimum chimney draught;
▪the method of operating the stove;
▪the use of fuel with a moisture content no less than 20%.
To keep the glass pane clean, it is advised to add the recommended quantity of fuel and to position it centrally
on the grate and as far from the glass panel as possible.
In the case of a build-up of tar on the glass pane, we recommend increasing the intensity of the burning process
by opening the throttle and the glass pane should normally clean automatically.
4.5. Operation in adverse weather conditions and in the rst period of
use
In the rst period of use or in adverse weather conditions (e.g. during a fog, on damp and rainy days, in weather
with strong gusty winds or when outdoor temperature exceeds +15°C), the chimney draught may become too
weak to remove all combustion gases. To oset this negative eect, the stove should be loaded with the small-
est possible amount of fuel or additional draught regulators should be used.
4.6. Removal of ash
Depending on the amount and type of burning fuel:
▪use a poker to rake the ashes through the grate into the ash pan;
▪after collecting the ash, take out the ash pan and empty it;
▪the ash pan can only be emptied when it is cold; it should be done, at the latest, before lighting a new re;
▪before emptying the ash pan, make sure that it does not contain any leftover embers which might cause
a re in the waste bin.
NOTE:
Take care not to overll the ash pan. If the ash pan is too full, it will hinder the inow of air under
the grate, hindering the burning process or, in extreme cases, even making it impossible to light
the stove.
If ash remains in the ash pan too long, it may result in premature corrosion.The ash from burnt wood may
be used as compost material or fertilizer.
4.7. General comments
Things to be done:

16
▪make sure that the door of the hearth (combustion chamber) are closed (unless they need to be opened
for maintenance purposes);
▪prior to lighting up after a prolonged shutdown period, check the ue pipe in the chimney and the hearth
to make sure that they are unobstructed and clean;
▪during the performance of any maintenance or operation-related tasks, remember that the components
of the stove can be very hot. Therefore, it is necessary to wear protective gloves;
▪for any repairs of the stove use only spare parts produced by its manufacturer;
▪all repairs must be performed by a qualied installer;
▪during the operation and use of the stove, follow the basic safety rules.
It is forbidden:
▪to leave any ammable materials or items sensitive to high temperature near the glass of the stove;
▪to use the appliance when its glass is broken;
▪to extinguish the hearth re with water;
▪to let children come near the appliance;
▪to make any structural changes or to alter the rules of installation and use without prior written consent
of the manufacturer;
▪if any malfunctions are detected, the re must be extinguished immediately.
NOTE:
In emergency situations, extinguish the re by covering the fuel with sand or cold ash.
DO NOT USE WATER!
If the stove does not function correctly, any maintenance work may only be carried out after
ensuring good ventilation of the rooms, as well as the assistance of another person equipped with
a dry-powder extinguisher.
When the burning process is slow, large quantities of organic products of combustion are produced, which may
lead to the build-up and ignition of creosote in the chimney duct. As a result, the so-called chimney re breaks
out, which may spread to the whole building.
In the case of a chimney re, please do as follows:
▪cut o the inow of air to the stove by closing the throttle of the cold air inlet;
▪close the rotary damper valve of the combustion gas ue (if installed in a given model);
▪close the door of the stove tightly;
▪dial 112 or 998 to alert the local Fire Department.
5. MAINTENANCE
To ensure safe and problem-free operation of the appliance, observe the following guidelines:
▪perform periodic maintenance tasks in a timely manner – have the stove inspected by a specialized servic-
ing company at least once a year;
▪keep the following components clean: glass pane, combustion chamber with the ash pan and the chimney
duct;
▪empty the ash pan regularly - if ash remains in the ash pan too long, it may result in corrosion.;
▪make sure that the combustion chamber is cleaned and serviced with a frequency which is appropriate
for a given type of fuel;
▪make sure that steel or cast-iron elements inside the stove are cleaned with appropriate tools such as:
brush, scraper and poker; use protective gloves;
▪any maintenance activities may be only performed after the re has been extinguished and the stove has
cooled down;
▪clean the ceramic glass pane of the stove with a kitchen paper (paper towel). It should be moistened with

5.2. Chimney and ue cleaning
The stoves have a detachable steel deector above the ceramic deector that allows you to easily and safely
check the cleanliness of the chimney and allows for its possible cleaning. To do this, follow these steps:
water and then collected with a bit of clean ash from the inside of the grate, avoiding direct contact with
steel elements and cast-iron devices. By rubbing the glass with so prepared moistened paper, we can eec-
tively dissolve the tarnish - so that it can be wiped with a dry paper towel. All agents used to clean the glass
must not contain abrasive materials causing its damage (scratching);
