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 12-15PA. If the draft is
greater than 17Pa, 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 parts recommended 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 is should be vented during the first firing.
It’s not recommended 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.
During firing, use protection gloves because the door handles get heated.
National and local regulations for the installation of the furnace must be respected.
In a case of non-compliance with instructions given in this manual, manufacturer does not take any kind of
responsibility for caused damage.

Hydro stove with back boiler are intended for heating residential space. An integral part of the installation is
a temperature safety relief valve for thermal discharge that serves as thermo safety of possible overheating.
It is recommended “ Caleffi 544 ½” shown in Figure 2
Fig 2.
Function:
Drain valve for thermal protection limits the water temperature. They
are intended for cooling of heating hot water when the temperature
reaches the limit of 95 C. If the probe is immersed in the hot water
outlet from the boiler registers the increase in temperature gives a
signal to open the valve to the cold water from the local installation
introduced into the system and cools it until the excess hot water goes
to the drain.
They are intended for installation in systems where it is not possible to
install the valve directly to the boiler body (not exist without heat
exchanger)

CAROBNA HYDRO 6/ 20
INSTALING THE STOVE
Stove must not be set up near the wooden parts, refrigeration devices, 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 flammable 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 protection sheet metal - lateral width of 10 cm and 50 cm in
the front.
Because of its weight, the stove must be installed on the appropriate base. If it does not satisfied
necessary standard, you must take appropriate measures to make it possible (e.g., 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 grids.
Fans that work in the same room where the stove is installed may make interference with 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 operation 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 3 . Put a candle near
the chimney connection drain. If the flame bends towards drain, the draft is satisfying (Figure 3b). If the flame
doesn’t bend or bends a little, that indicates poor draft(Figure 3a).
If there is poor draft in the chimney (Figure 3a), 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.

Defaults of the chimney may be (Fig. 4):
1. Chimney is lower then top of the roof,small cross section of the exit
2. Too large slope
3. Abrupt alteration of the direction of smoke channel,
4. Stove or other device connected to the same smoke channel,
5. Bulges in the smoke channel,
6. Cranks,
7. Foreign body or deposited smut,
8. Too deep installed pipe,
9. Ventilator or other device which createssub-pressure in the room
10. Leaky or open aperture for cleaning

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 fuel into the fire place (chopped wood to non-greasy wrinkled paper), and light a fire
• leave open primary air regulator (opposite of clockwise direction) until the flame gets stable and after
having stabilized the flame, control burning intensity with drafts regulator (Fig. 1, pos. 9)
• 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 briquettes are lit and then
reduce the draft in half.
• when adding fuel, open the fire door (Fig. 1, pos. 4) 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 its
spreading into the room.
Regulating the draft in the stove, 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. 11). Combining primary air regulator 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.
Recommended fuels are briquettes and wood.
You must not use gasoline and similar fuels, because by using liquid fuels you create conditions for damaging
the stove and to provoke an explosion.
Attention!
• Do not use organic wastes 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 stove when there are bad weather conditions for the stove andin 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 stove.
For proper operation of the stove it is nesessary:
- Regular cleaning of stove and chimney
- Regular room ventilation or better combustion
- Regular ash tray cleaning
- Accumulated slag and unburned material regularly remove from the grid

CAROBNA HYDRO 9/ 20
HANDLING 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 top of it 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 creosote. If that happens in some bigger quantity, 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 stove is designed to operate in periodic mode. To maintain the required nominal power, combustion
chamber is periodically filled with reestablished amount of fuel.
Stove is not designed to operate in continuous mode of heating or in accumulating temperature mode.

I - regulation of secondary air
Set the secondary air in the closed position during firing and kept in this position until the establishment of
the working regime of burning after insertion of larger pieces of wood. After this time set the controller in
position open and hold it in this position all the time stove functioning. The secondary air is used to clean the
glass (air wash) on the firebox door and for better combustion.
Power regulation is the furnace is obtained by adjusting the regulator of the primary and secondary air

When installing a safety valve pay attention to the direct connection to water, sewer, and that valves
(faucets) should always be open.
It is required the installation of a four-way mixing valve at certain place (Figure 7a and 8a) or a tubing pipe
contact thermostat (Figure 7b and 8b), set to 55 ° C. Their installation is required for the prevention of
condensation on the walls of the boiler in the furnace (condensation boiler adversely affect the service life of
the boiler and on the performance of the product by creating a resin on the walls of the boiler, which
represents an insulator so the product does not have declared characteristics).
Instalation on closed central heating system
One of the aspects of mounting installations is depicted on figure 7a.and 7b.
- Safety valve must be installed in the vicinity of boiler and must be adjusted for pressure of max. 3 bar.
