WARNING BEFORE USE
To keep your stove working properly, it is important to read this manual and strictly stick to
the instructions for use and handling.
For combustion use solid fuels such as wood and wood briquettes. It is forbidden putting
explosive devices and materials combustion chamber or the limited thermal furnace. It is
forbidden to keep flammable materials near the stove.
For proper combustion, in normal operating mode, draft in the chimney should be 10-12PA. If
the draft is greater than 15Pa, the valve should be installed in the chimney.
Room where the stove is positioned must be vented regularly for the fresh air needed for
combustion.
Some parts of stove heat up during operation and it takes appropriate precaution when
handling it. Do not allow children to handle and play near the stove.
Only spare partes reccomended and allowed by the manufacturer should be installed on the
stove . You must not make any changes on the stove.
With first firing there might show a mild smoke, especially from the plate’s surface. It is a
common appearance that occurs due to combustion deposits on the plate’s surface
(corrosion protection, paint, dust, ....). The room where the stove should be vented during the
first firing.
It’s not reccomended connecting the stove to the common chimney because it can adversely
affect the required draft.
Device that uses gas as fuel must not be connected to same chimney.

DIMENSIONS OF THE STOVE

INSTALLING THE STOVE
Stove must not be set up near the wooden parts, refrigeration parts, plastic furniture and
other flammable materials because during operation (during fuel combustion) it achieves
high operating temperature that is distributed on the outside of the furnace. Minimum
distance between the stove and the surrounding elements is 50 cm, and the from flamable
materials 80 cm.
If the ground on which you set the stove is made of easily flammable material (wood, warm
floor, laminate ...) you need to set under the stove a protetion sheet metal - lateral width of 10
cm and 50 cm in the front.
Because of it’s weight, the stove must be installed on the appropriate base. If it does not
satisfie necessary standard, you must take appropriate measures to make it possible (eg,
weight distribution).
Connect the stove to a chimney and flue pipes through the connector on top of the furnace,
so as to ensure adequate tightness and flow of smoke from the stove to the chimney. Flue
pipe must not be drawn too deeply into the chimney that would reduce the cross sectional
area and thus undermined draft in the chimney. Do not use reducers which reduce the cross
section of pipe smoke.
The stove requires insertion of fresh air in the room where it is installed, with surface
openings for insertion of fresh air should not be less than 0.4 dm ². The unit for fresh air set
outside the common room for ventilation, which must be insured by door and gride.
Fans that work in the same room where the stove is installed may make interference wit the
the stove. Also, all devices or ventilation that creates negative pressure in the room where
the stove is installed, must be set in the way that does not make decompression that
prevents normal operation of the furnace.
Before installing the stove, check the chimney drafts because it is a key factor in the proper
functioning of the stove. Draft depends on the proper opration of the chimney and
meteorological conditions. One of the easiest ways to check the draft in the chimney is with a
candle flame, as shown in Figure 2 . Put a candle near the chimney connection drain. If the
flame bends towards drain, the draft is satisfying (Figure 2b). If the flame doesn’t bend or
bends a little, that indicates poor draft(Figure 2a).
Figure 2a Figure 2b
If there is poor draft in the chimney (Figure 2a), check the chimney operation. The chimney
should be located inside the building, and if it’s located on the external walls of the building,
it’s recommended insulation chimney.

Disadvantages of the chimney (Figure 3): `
1. The chimney is higher than the top of the roof, a small cross section of the output,
2. Excessive slope
3. A sudden change of direction of the flue channel
4. Stove or some other device connected to the same flue channel,
5. Bulges in the flue channel
6. Cracks
7. Alien body or accumulated grime,
8. Tube inserted too deeply,
9. Fan or other device that creates a vacuum in the room
10. Unsealed or opened cleaning hole

IGNITION AND LIGHTING
Before the first firing, wipe all painted surfaces with clean and dry cloth, in order to avoid
burning impurity on the oven and creation of unpleasant smells.
Start the fire in the stove by following order:
• open the fire door,
• place the fluel into the fire place (chopped wood to non greasy wrinkled paper)
• light a fire
• leave open primary air regulator until the flame gets stable and after
having stabilized the flame, control burning intensity with drafts regulator (Fig. 1, pos. 2)
• secondary air regulator leave opened until the flame gets stable and after
having stabilized the flame, control burning intensity with regulator (Fig. 1, poz.3)
• close the firebox door,
• after creating a basic flame insert larger pieces of wood or briquettes in the firebox, and
close the firebox door. If you use briquettes as a fuel, you must wait that all biquettes are
lit and then reduce the draft in half.
• when adding fuel, (Fig. 1, pos. 1) open the fire door step by step
wait for 4-5 seconds, and then slowly open it wide.
Do not open the door suddenly, when there’s a strong flame in the combustion chamber, it
may come to it’s spreaading into the room.
Regulating the draft in the stow, you can regulate temperature, power and the combustion of
fuel, and this is done by running draft regulator on the firebox door (Fig. 1, pos. 2).
Combining primary air through the regulator on the firebox door and secondary air over the
leverage above the firebox door (Fig. 1, pos. 3) you get desired combustion .
Stove contains auxiliary tools in order to facilitate its maintenance.
Stove has a lever for shaking grid, located in the front of the stove, by slow back and front
movements while the stove is running, which allows the passage of primary air.
Recommended fuels are briquettes and wood.
You must not use gasoline and similar fuels, because by using liquid fuels you crate
conditions for damaging the stove and to provoce an explosion.

Attention!
• Do not use organic waste as fuel, food residue, plastic, combustible or explosive materials,
which combustion disturbs the proper functioning of the stove and may cause damage and
environmental pollution.
• Increased ambient temperature can cause poor air circulation (drafts) in the chimney, and
in that case is recommended more frequent firing in smaller quantities
• Avoid using the oven when there are bad weather conditions for the the oven and in the
case of strong wind, because it reflects the required vacuum in the chimney. In these cases
there may occure potential return of smoke in the room where the stove is placed. Ignition is
difficult then.
We recommend firing every hour with the amount of fuel in the combustion chamber up to
15cm with cross stacking wood for better airflow.
After each refilling, it’s reccomender to leave the oven running in full speed for 30 minutes,in
order to destroy all volatile elements that may cause condesation in the oven.
For correct stove operation it takes:
- Regular cleaning of the stove and chimney
- Regular room ventilation for better combustion
- Regular ash tray cleaning
- Accumulated slag and unburned material regularly remove from the grid
HANDLING THE STOVE OPERATION
Start a fire with a moderate flame in order to avoid thermal shocks.
The following amounts of wood are inserted only after the previous volume burn.
Do not allow that ashes and unburned accumulate on the grid and to ta pit that way. Clean
the grid.
Open the door slowly and carefully, allowing that way equalization of pressure in the firebox
and in the room, otherwise it might cause the smoke in the room.
The stove is designed and intended for use with firebox door constantly closed, except
during refueling. Do not open the door with no need.
The wood must be a maximum of 20% moisture content for maximum fire effect. Otherwise
the tar gets separated which with water steam may crate creosite. If that happens in some
bigger quantitiy, it may lead to a chimney fire. You will most easily recognize chimney fire by:
the characteristic sound that comes out of the chimney like loud roaring, visible flames
coming out of the chimney, high ambient temperatures of surrounding walls and the
characteristic smell of burning.

If there comes to the fire do the following:
• Immediately call the fire squad
• muffle oxygen supply to the chimney and turn off the stove
• Do not insert anything into the chimney and make sure that the fire does not spread to the
wooden construction or other combustible materials in its nearby.
• DO NOT pour water into the stove or chimney
• A fire in the chimney can be extinct only with dry powder
• Water can extinguish only a surrounding material
• Do not cool the surrounding walls with water
Note:
If the fire in the stove for some reason becomes dangerously strong take the following
measures: close air dampers that provide air for combustion. If it is necessary put in the
firebox specially prepared sand for this purpose or non-combustible fire blanket. It would be
good to have a fire extinguisher.
Before the second charging, clean the grid in order to provide the fresh air.
Regularly clean the ash pan making sure that there is always a place for ashes.
The furnace is designed to operate in periodic mode. To maintain the required nominal
power, combustion chamber is periodically filled with prestabled amount of fuel.
Furnace is not designed to operate in continuous modeof heating or in accumulating
temperature mode.
I - regulation of primary air
Primary air regulator set to the open position (Figure 4a) during ignition and hold in this
position until the stove operation gets stable, after insertion of larger wood or briquette
pieces. After that, the controller set to the closed position (for burning wood and wood
briquettes - Figure 4b) and keep it in that position when the oven. When closed, the regulator
prevents the air intake below the grille, which reduces the intensity of the fire. If the fuel is of
poor quality, partially open the regulator.
Figure 4a Figure 4b

II - secondary air control
Secondary air regulator set to "max" (Figure 5) during ignition and hold in this position until
the establishment of a stable stove operation after insertion of larger pieces of wood or
briquettes. After that, depending on what position is the regulator will depend the intensity of
the combustion. If the secondary air regulator remains in the open position, intensity of
burning will be maximized and if the secondary air control in the "min", intensity burning will
be minimal.
Stoves power control is obtained by adjusting the regulator of the primary and secondary air.
Figure 5.

CLEANING AND MAINTENANCE
Regular and proper cleaning allows proper operation and long life of the stove. All cleaning
the interior or exterior surfaces are always performed in a cold oven.
Cleaning exterior surfaces - is done with a soft cloth that will not damage the surface of the
stove. Cleaners of chemical origin can damage the surface of the fire place and cannot be
used. Painted surfaces must not be cleaned with abrasive products.
Cleaning inter surfaces – when cleaning use protective gloves.
Clean the bottom of the oven from accumulated ash and pick up small unburned pieces of
the grid, clean the ashtray and ash accumulated in the interior of the fireplace.
Cleaning glass surfaces - glass on the firebox may get dirthy during the operation.. For
cleaning use a mild detergent. Do not use abrasive cleaners because they can damage the
surface of the glass. Clean the glass only when cool.
Cleaning and maintenance of the chimney - chimney cleaning and control is
recommended at least once a year and after a long downtime. Regular maintenance and
control of the chimney will prevent the occurrence of fire and poor operation of the stow.
