INSTALLATION AND CONNECTION TO A CHIMNEY
The cast-iron stove is designed in such a way it would be possible to connect it to a
suitable chimney using fume tubes, elbow bends and other connecting elements. When
assembling and operating the stove, it is necessary to observe all the local regulations, national
and European standards in force. It is also unconditionally necessary to follow the fire safety
regulations. The stove may be installed in any usual space in accordance with STN 33 0300.
Warranty applies to the stove only if it was installed, assembled and put
into operation by the authorised serviceman, which is proved by the
drawn and acknowledged protocol kept by the relevant authorised
servicing organisation.
The stove assembly shall only be carried out by the serviceman trained
by the stove manufacturer. The stove assembly should be carried out
minimally by two adult persons since it is required by the weight of the
stove.
Find a place where the stove shall be installed. Check for the rigidity of the structure
under the stove so that it would safely carry the weight of the stove in vertical position. As long
as the rigidity of the structure under the stove is insufficient, it shall be necessary to adopt the
measures that would sufficiently reinforce the floor under the stove (e.g. the use of solid, heat-
resistant insulation pads that would distribute the load). When assembling, operating and
placing the stove on the selected place, all the local regulations, including those ones regarding
the national and European standards must be mandatory followed. Always ensure the supply of
a sufficient amount of combustion air on the place where the stove is located, in particular in
the rooms where exhausting device, air conditioning and tightly closable windows and doors are
located.
Air exhausters working in the same room or space as the appliance may
cause problems!

-9-
There must be non-flammable, solid heat insulating pad symmetrically oriented with the
stove, fixed to the floor using four screws, under the stove. The pad must overlap the front edge
of the stove contacting the pad minimally by 50 cm, the side edges and the rear edge of the
stove should overlap minimally by 30 cm.
The assembled stove should be connected to the chimney using the chimney tube, elbow bend,
distance ring, rosette only after 24 hours since the installation cement must get hardened. The
chimney connector must be secured with two screws to the stove (from top and bottom)
against protrusion.
The stove may be installed in the common environment pursuant to STN 33 0300 standard,
while strictly observing fire protection pursuant to STN 92 0300. While installing the stove, it is
necessary to observe all the relevant safety, hygienic and project guidelines in accordance with
the Regulation No. 84/97. The stove must always be connected to the chimney in a suitable
way, the chimney has to be approved for the use by chimney authority in accordance with STN
73 4210 and STN 73 4201.
The fume duct should be as short as possible and it must constantly ascend towards the
chimney. The length of fume duct may be maximally 1.5 m. Since the chimney effect changes
during a year for various reasons, we recommend installing the regulation flue flap in the
chimney.
The stove may work and reach the declared efficiency only in the case it is connected to the
chimney with the required parameters. The cross-section of the chimney should be minimally of
150 mm diameter and its height should be minimally 5 m. It is recommended for a good
performance to have the stove connected to a separate chimney; it may be connected to the
common chimney with several appliances, as long as the sufficient chimney effect of 10 Pa is
ensured. As long as the stove is connected to the common chimney with several appliances,
they must be closed when out of operation. Otherwise they might sufficiently affect the other
appliances connected to the common chimney.
It is inevitable to have the connecting chimney elbow bend or chimney tube placed onto the
exhausting neck of the stove secured against release using the screws and fixed to the stove,
the screws are supplied together with the stove and they have a thread on the relevant place.
The fume elbow bends and tubes must be always firmly and tightly interconnected on every
connection in the direction of chimney effect (Fig. 3) with the overlap of at least 40 mm. The
connecting hole in the chimney must be equipped with metal distance ring to which the fume
tubes or elbow bends are inserted. The fume rosette shall be placed on the fume tube at the
entrance of the fume tube to the chimney as a decorative ending.
The stove must be connected to the chimney meeting the STN 73 4210 and STN 73 42 01
standards. Prior to the stove assembly, consult the revision technician with regards to your
intention to assemble the stove. The stove must have the sufficient space around in all
directions so that it would be possible to clean the stove, fume duct and chimney.

SAFETY REGULATIONS AND PRECAUTIONS
It is forbidden to make any modifications on the stove.
Only the spare parts made by the manufacturer of the particular
stove may be used.
In the case there are flammable construction materials and objects with flammability
degree B, C1, C2 pursuant to STN 73 0823 near the stove and its fume duct, place the stove with
the relevant fume duct in a safe distance being minimally 1,000 mm in all directions, including
upwards. The distance may be reduced to half, but there must be construction and technical
measures made using the non-flammable, thermally insulating materials with the thickness of at
least 5 mm (shields, metal sheets with sufficient dimensions overlapping the contours of
flammable objects from each side minimally by 150 mm and protruding upwards with its top
area minimally by 300 mm, with the sufficient flow of cooling air around the shields and metal
sheets). The distance between the flammable object and the protecting board, the clean air gap
must be minimally 25 mm, in order to avoid the risk of fire.
As long as there are the objects made from the materials with flammability degree C3 in the
proximity of the stove and its fume duct, the safe distance must be increased to 1,500 mm. The
same applies to the objects made of materials the flammability degree of which cannot be
safely specified.

CAST-IRON STOVE OPERATION
Only adult and competent person may operate the stove!
When operating the stove, always use the heat resistant gloves supplied
with the stove.
The stove is delivered already burned out at the temperature of 260 °C for 40 minutes,
in the disassembled condition. After the stove assembly, after 24 hours of cement hardening
and connection to the chimney, it shall be necessary to slightly make a fire in them so that the
individual parts could find their place (the thermal running-in as a whole) i.e. the running-in
heating. It is necessary to burn very little amount of wood for ca 30 minutes (first heating) in the
stove. Then let the stove slowly cool down.
FUEL
The stove was designed for the combustion of wooden split and whole logs of a
reasonable circumference up to ca 28 cm (dried for two years) so that the wood could freely
pass the loading hole to the furnace. The recommended lengths of loaded wood: approximately
from 15 to 40 cm, according to the stove type.
THE OVEN OPERATION AT NOMINAL POWER AND HEATING-UP
1. Turn the supply of primary inlet combustion air (Fig. 1 - position d) to MAX position
according to the pictogram on the stove (Fig. 2 - position a). The lever position
should be used mainly when making a fire.
2. Open the supply of secondary inlet combustion air to maximum (Fig. 1 - position e) in
the similar way to MAX position according to the pictogram on the stove (Fig. 2 -
position b).

-13-
3. Empty the ash-can and clean the space for ash-can (Fig. 1 - position b). Completely close
the ash-can door (Fig . 1- position b) up to the stopper of the ash-can door. It must
be closed.
4. Make fire through the open loading door (Fig. 1 - position a) using thin dry soft wood
and kindling agent (you can buy it in a store) on a clean grill. Then immediately close
the loading door (Fig. 1 - position a).
5. When the soft thin wood gets burn sufficiently, open the loading door (Fig. 1 - position
a) and add reasonable amount of slightly larger, thin, ready-made hardwood and
close the loading door (Fig. 1 -position a).
6. When the hardwood burns in an adequate way, too, close the supply of primary sucking
combustion air to minimum (Fig. 1 - position d), open the loading door (Fig. 1 -
position a) and add the reasonable amount of thicker hardwood, you shall use to
heat with and close the loading door (Fig. 1 - position a). The primary supply of air
should be again open to maximum (Fig. 1 - position d) and after the load burns well,
set the supply of primary air (Fig. 1 –position d) to the minimum position (the
control of the secondary combustion air shall remain in MAX position), the flame
must be still. The wood can be loaded to the stove in horizontal, askew position as
well as vertically. The procedure of air adjustment must be repeated upon every
load.
7. In a suitable time, it is necessary to poke the coals at the bottom of the grate using the
mobile grill (Fig. 1 - position c) holding the grip. Grasp the grip (Fig. 1 - position c)
and shift it several times towards you and away from you with the ash-can door
closed (Fig. 1 - position b). Use heat-resistant gloves!
Open the loading door in two strokes. At first, open the door just a little,
by approximately 1 to 2 cm, stay for ca 1 - 2 seconds in the position, still
firmly holding the white ceramic grip in your hand with a heat-resistant
glove. Then you can open it to maximum. Thus you shall restrict to
minimum the unforeseen and unwanted unpleasant spreading out of
odour and combustion products to the external area in the proximity of
the stove.
Closed stove in operation, which had prior been filled up with
recommended fuel, is to be opened only after the fuel has burned out
under the level of the lower stove edge. Otherwise there is the risk of
burn, back blaze of flame through the loading door out of the stove and
penetration of fume to the space where the stove is installed.

-14-
THE STOVE OPERATION AT REDUCED POWER
The stove may be operated for longer time period at the reduced power. When the
stove is reasonably heated up and the layer of loaded wood burns out, clean the grill by shifting
while holding the grip (Fig. 1 - position c) and let just the hot coals on the grill forming a layer of
one up to two centimetres height. The ash-can door (Fig. 1 - position b) must be completely
closed. Open the loading door (Fig. 1 - position a) and load the maximum amount of fuel to the
combustion area (as much as can be put inside, approx. 6 kg) - dry hardwood in horizontal,
askew or vertical position (the vertical position of wood is recommended in particular near the
window so that the loaded wood would not obstruct the glass when closing the door). Well
stacked wood in the combustion area is the precondition of a long combustion per one fuel
loading. Duly close the loading door (Fig. 1 - position a). After a short reasonable time, when the
loaded fuel starts burning (the primary and secondary air control should be set to maximum),
set the control for the adjustment of the primary air (Fig. 1 - position d) to the minimum
position. The secondary air control (Fig. 1 position e) should be moved gradually from the
maximum position to the minimum position, monitor the flame through the loading door.
When the flame is small and looks like it would soon stop burning, terminate the adjustment of
secondary air (Fig. 1 - position e). Such heated up stove can heat for approx. 12 hours depending
on the type of the stove, heating and weather conditions. The fuel doses shall be combusted in
an efficient way for a long time without any external intervention.
As long as you want to interrupt the above described process and transfer to the intensive
heating, set the regulation controls of the primary and secondary air according to the stove
operation to the nominal power.
STOVE OPERATION TERMINATION
As long as the fuel in the stove got burned out and you do not want to continue with
heating, set all the regulation controls to minimum (Fig. 1 - position d, e). Thus you shall reduce
the supply of combustion air to the allowable minimum. In addition, the outlet of chimney
products shall be reduced to minimum, whereby the heat leakage through the chimney shall be
mitigated, and completely close the ash-can door (Fig. 1 - position b). The accumulation mass
(crashed glass) poured at the sides of the ash-can shall release the saved heat to the
surrounding area even after the stove went completely out.
Should any surface external parts of the stove got red heated when
heating intensively, immediately set the supply of primary sucking air to
minimum, nothing special happens, everything is OK, you can continue
heating. Of course, while observing all fire and safety regulations as well
as the Operation Manual supplied by the manufacturer of the stove. The
shade of the surface treatment of the stove can change after it cools
down, which is allowable.

-15-
When heating during warmer period, in particular upon a sudden change
in weather (warming up), the chimney effect may be unfavourable
(poor). It is demonstrated by a slow, tame heating in the grate, the
combustion products are not perfectly carried away. In that case, it shall
be necessary to poke the fire in more intense way and more frequently,
to load smaller doses of fuel, the ash-can should be less full with ash and
all the regulation controls (primary and secondary flap of combustion air
sucking) should be open to maximum.
IMPORTANT WARNINGS
During the stove operation never open or lift the inspection hole (Fig. 1 -
position f), there is a risk of fire, burn, suffocation with fume and
intoxication with CO gas (it is extremely poisonous gas, carbon oxide,
chemical symbol CO, it is generated during imperfect combustion, it is
invisible and odourless)!!!
The stove is made of the individual parts (sections), freely placed onto each other and
cemented on the connections, which ensures their stability and tightness.
It is forbidden to willingly and inadvertently impact the stove with anything and in any
way, in order to prevent the breach of any stove part on the cemented connections.
Furthermore, nothing can lean on the stove even when it is cold.
It is also forbidden to manipulate with the stove parts during heating in any other way
but using the method specified herein!
The stove must not be put into operation under any circumstances that would lead to
the risk of a temporary cause of the explosion of gases, dust or vapours and it also may
not be in operation during the work presenting the risk of explosion or fire (for example
the bonding of floor covering, etc.)
The stove may be operated according to the Operation and Service Manual only by
adult persons with legal capacity.
No hazardous substances may be present on the place where the stove is located.
It is forbidden to pour any liquid, snow, ice, powder and loose material over the stove.
No loose, powder, spray or gas materials and particles such as flour, the contents of
sprays, etc. may be dispersed onto or into the stove or its surroundings.
The power of the stove may not be increased in any other way but using the regulation
controls installed by the manufacturer on the stove.
When handling with the regulation controls, the loading glass door, tube door, baking
tray, grill in the furnace ash can door, etc., always use the supplied handling heat-

-16-
resistant gloves, otherwise there is a risk of burning.
Do not throw the explosive objects to the proximity of, onto or inside the stove or the
furnace.
The ash shall be carefully taken out to a dedicated container after it had cooled down.
Use heat-resistant gloves.
Do not use damaged, non-functioning stove. The user shall be responsible for the
professional repair.
It is forbidden to use waste, wood sawdust, wood chippings, loose substances, powder
coal, plastic, rubber, liquid fuel, liquids, alcohol, gas, any objects soaked with volatile and
crude oil substances, clothes, etc. as a fuel. Only the fuel recommended by the
manufacturer of the stove may be used.
-When heating using the stove it is necessary to always ensure the reasonable venting,
also in the case of the concurrent operation with other thermal device.
-Regularly check the amount of ash deposited in the fume duct and elbow bends, as well
as in the shafts of the stove, minimally once every three months. If necessary, clean them.
-In the case of fire in the chimney, you must close all the air bleeds of the stove as soon as
possible. Immediately start closing all the inlet controls to minimum, completely close the
ash-cab door. Do not open the loading door, do not open the top round cover. Immediately
call firemen and inform them about the event and its place.
-The term "Stove Operation" covers the process, from the moment of the fist ignition of fuel
in the stove till the complete burning out of the fuel and the extinguishing of all hot coals in
the stove, including the ash-can and at the same time the cooling down of the entire surface
of the stove to a pleasantly sensed temperature when touching it.
-During the stove operation, continuously check the stove function and fire safety. It is
necessary to check the following:
-The condition of the fuel in the stove, the position of the air sucking regulation
controls , the position of loading door, ash-can door and the amount of ash in it (do
not let it get filled with ash to the maximum capacity as this impairs the economy
and ecology of burning. Up to ca ¾ of capacity would be enough.
-Notice the character of fire in the various phases of burning, its changes in shape,
colour and sound.
-Notice the grill, whether it is not clogged with ash,
-Notice whether the loading door is always correctly closed.
-The increased attention should be paid to the present persons under the influence
of alcohol or narcotics, diseased, weak and paralysed persons.
-Notice whether someone placed an unsuitable object to the proximity of the
heating or cooling down stove.
-In particular, warn the children of the possible risk of burning and always take care
so that they would not get to the dangerous distance from the stove, in order to
prevent their burning and falling over, despite that they are sufficiently away from
the stove at first glance.
-Prevent the free uncontrolled movement of animals in the proximity of the stove.
-Do not put any live animals and any objects into, onto the stove, into the furnace
