WARNING BEFORE USE
To obtain proper operation of our cooker, it is important to read this manual and
strictl observe directions for use and handling.
For combustion, use solid fuels like woods, briquettes and low-caloric coal. It is
forbidden to put explosive devices and materials into the firebox or on the plate. It is
forbidden to keep combustible materials in direct vicinit of the cooker.
For proper combustion, in normal operating mode, draft in the chimne should be 15-
17 Pa. In case if draft is higher then 17 Pa, flap should be installed into the chimne .
It is necessar on regular basis to ventilate room in which cooker is located due to
inflow of fresh air necessar for combustion.
Cooker parts get heated to high temperatures during operation and appropriate
attention is necessar during handling. Do no allow children to handle and pla in
vicinit of the cooker.
Onl spare parts approved b the manufacturer ma be installed on the cooker. Do
not make an changes to the cooker.
At the first firing up, slight smoking ma occur, especiall from the surface of the
plate. It is common appearance which originates due to combustion of deposits on
the plate surface (anti-corrosive protection, color, dust....). Room in which cooker is
located should be ventilated during first firing up.
Do not allow part of the cooker to become incandescent.
On the same chimne , do not install an device which uses gas as fuel.
During firing up, use protective gloves since door handles and vessels are heated.
DO NOT USE COOKER:
If it is not connected to installation
If installation is in lack of water
If installation is broken
Upon installation, observe all national and local provisions for installation.
In case of non-observance of t is manual, manufacturer will not accept any
responsibility for damages on t e cooker.

INSTALLATION

Do not put the cooker in direct vicinit of wooden elements, cooling devices, plastic
parts of the furniture and other combustible materials, since it creates high working
temperature which is distributed at the exterior of the cooker (at the combustion of
fuel). The least distance between cooker and surrounding elements is 50 cm, and
combustible materials 80 cm.
If surface on which cooker is to be positioned is made of easil combustible material
(wood, warm floor, laminated floor...) it is necessar to install metal sheet protection -
lateral width 10 cm, in front 50 cm.
Due to its weight, it is necessar to install cooker on the floor with appropriate
carr ing capacit . If latter does not fulfill requirements, please take proper measures
to achieve it (e.g. distribution of weight).
Cooker is to be connected with chimne through flue pipes and via connection on the
back side of cooker, in order to provide adequate sealing and smoke flow from
cooker to the chimne . Flue pipe ma not be installed too deepl into the chimne to
avoid reduction of cross-section of the surface thus impairing draft in chimne . Do
not use reducers which would reduce cross-section of the smoke exhaust pipe (flue
pipe).
Cooker requires intake of fresh air into the room in which it is installed, whereat
surface of the opening for intake of fresh air ma not be smaller then 0,4 dm². Device
for intake of fresh air is to be mounted outside collective room for ventilation which
must be secured with doors and grid.
Ventilators which work in the same room in which cooker is mounted ma create
disturbances with the cooker operation. Also, all devices or air conditioning which
make sub-pressure in the room in which cooker is installed must be adjusted not to
make decompression which disables normal operation of the cooker.
Prior to installation of the cooker, check draft in the chimne since it is one of the ke
factors of proper operation. Draft depends on accurac of the chimne and
meteorological conditions. One of the simplest aspects for checking of the draft in
the chimne is using candle flame, as illustrated in the figure 2. Candle flame is to be
offered to connection opening of the chimne and, if it swa s towards opening, draft
is satisfactor (fig. 2b). Weak swa ing of the flame is indicator of weak draft (fig. 2a).
Fig. 2a. Fig. 2b.

If draft in the chimne is weak (Fig. 2a), check accurac of chimne . Chimne should
be located within interior of an object, and if it’s on external walls of an object, it is
recommended to insulate the chimne .
Fig. 3
Defaults of the chimne ma be (fig. 3):
1. Chimne 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. Cooker or other device connected to the same smoke channel,
5. Bulges in the smoke channel,
6. Cranks,
7. Foreign bod or deposited smut,
8. Too deep installed pipe,
9. Ventilator or other device which creates sub-pressure in the room
10. Leak or open aperture for cleaning

INSTALLING COOKER INTO THE SYSTEM OF WATER HEATING
-for intake and output of water into the s stem of central heating, connections of of
1" on boiler are anticipated.
- cooker ma be mounted on closed or open s stem of central heating.
Mounting to closed system of central eating
One of the wa of proper installation is shown on the picture 5.
-safet valve must be installed on the vicinit of boiler and must be set to pressure of
max. 3 bar (boiler is tested for 4 bar). Connection guide of safet valve must be as
shorter as possible and ma not be capable for closing. This guide, also, ma not
contain an valve or an other fixing.
- Closed expansion vessel is to be installed next to the boiler ad safet valve is short.
Volume of this vessel is to be determined based on capacit of boiler, thereat
propotion of 1kW:1l is valid.
- It is obligator to install safet thermal valve of boiler on anticipated place. We
recommend safet thermal valve Caleffi 544.

One of the aspects of installation is shown on fig. 6.
At this s stem, starting guide is to be installed with safet distribution guide of
expansion vessel and valve of boiler, and on starting guide valve of boiler is to be
installed, as well as pump and valve. Directl below open expansion vessel there
must be short connection of safet distribution guide and safet return guide, which
in winter prevents freezing of water in expansion vessel.
On safet distribution and safet returning guide there ma not be an fixture.
Expansion vessel itself must have overflow duct as shown on diagram 7. Volume of
expansion vessel is to be determined b the pattern:
V = 0,07x V water, (l), where V water is water volume and entire power plant.
Open expansion vessel is to be installed verticall above the highest heating bod .
At open heating s stem, gravitaion s stem of heating is possible.
Note: Mounting of heating and putting into operation of entire s stem should be
exclusivel carried out b expert who guarantees proper work of entire heating
s stem. In case of weakl designed s stem and eventual omissions upon works b
mentioned person, complete material responsibilit shall be borne exclusivel b
person who carreid out installation of heating s stem,not manufacturer,
representative or retailer of the boiler.
Important
• Installation of cooker should be carried out b expert according to appropriate
project design. Cooker construction enables connection to open or closed heating
s stem. All connections must be well sealed and tightened. Prior to operation,
complete installation should be inspected with water under pressure of 3 bar.
• upon installation of safet valve, pa attention to direct connection with aqueduct
and sewage, and if valves (taps) are alwa s open.
• If reinforced hose is used for connection with drainage opening, it must be removed
from back side of cooker.
At t e first firing up, it is necessar to inspect accurac of valve b short-term
overheating up to 100°C, and then inspect accurac of air flow regulator and
installation for distribution of hot water to radiators, as well as radiators themselves.

FIRING UP AND IGNITION
Prior to the first ignition, wipe all enameled surfaces of the cooker with dr mop to
avoid combustion of dirt on the cooker and creation of unpleasant scents.
Firing up in the firebox should be carried out as follows:
• open firebox and ashtra door and pull primar air handle,
• put into the firebox some firing materials (chopped wood on non-greas and
crumpled paper),
• fire up,
• ashtra door should be left open until stable flame occurs, and after closing,
intensit of the burning should be regulated on the air flow regulator, (fig. 1, pos. 3)
• close firebox and ashtra door,

• after creation of basic cinder, put into the firebox some bigger pieces of woods or
coal and close firebox door. If briquettes are used, ou must wait all quantit of fuel
to get ignited then to reduce air flow to half.
• at adding fuel, open firebox door (fig. 1, pos. 1) for onl few degrees, wait for 4-5
seconds, then open it wide ver slowl . Do not open it abruptl , because when flame
in the firebox is too strong, it ma effuse into the room.
B regulation of air flow in the cooker, ou set temperature, power and pace of fuel
combustion, and it is to be carried out b turning air flow regulator on the ashtra
door (fig. 1, pos. 4). Cooker has secondar air flow regulation due to improvement of
combustion and maintaining firebox glass clean. B combining primar air through
regulator on the ashtra door and secondar air via buttons above firebox door
desired combustion is achieved.
Cooker has auxiliar tools which serve to facilitate maintenance of the cooker.
Woods and briquettes are recommended for burning.
Do not use fuel oil, gasoline or similar as fuel for t e cooker, since use of
liquid fuels creates conditions for damaging of cooker and possible explosion.
Attention!
Do not use organic residues, food residues, plastic objects, combustible and
explosive materials as fuel, since their combustion disturbs proper operation
of the cooker and ma cause damages and pollution of environment.
Increased external temperatures ma cause weak draft in the chimne , thus it
is recommended more frequent burning in smaller quantities.
Use of the cooker in cases when meteorological conditions are bad and in
case of strong wind, it is to be maintained on proper sub-pressure in the
chimne . In indicated cases, smoke ma return into the room in which cooker
is located. Firing up is protracted in such cases.
We recommend burning on each 1h with the height of the fuel in the firebox up to 15
cm with crosswise positioning of the woods due to higher draft.
Upon each filling, it is recommended to let the cooker to burn at least 30 minutes
with maximal power, in order to burn all evaporable ingredients which are the reason
of creation of condensate in the cooker in this stage of combustion.
For proper operation of the cooker, it is necessar to:
• regularl clean cooker and chimne ,
• regularl ventilate rooms due to good combustion,
• regularl remove ash from ashtra ,
• regularl remove deposited gravel and unburned materials from the grid, using
cleaning accessories.

MANAGING OPERATION OF THE COOKER
Start firing up with moderate fire in terms of avoiding thermal shocks.
Following quantit of woods is to be inserted onl when previous quantit gets
burned.
Do not allow clogging of the grid with ashes and unburned fuel. Clean the grid.
Open the door slowl and carefull , not abruptl , enabling equalization of pressures
in the firebox and room, otherwise, it ma cause occurrence of smoke in the room.
Cooker is designed and provided for operation with constantl closed firebox door,
except during filling with fuel. Do not open door unnecessaril .
Wood must be with maximal 20% humidit for maximal burning performance.
Otherwise, tar and gases occurs which create creosote with water vapor. If creosote
occurs in larger quantit , fire ma occur in the chimne .
Fire in the chimne will be easil recognized as follows: characteristic sound which
comes from the chimne like loud hoot, visible flame which comes from chimne ,
high temperature of surrounding walls and characteristic smell of flare.
If fire occurs, take following steps:
Immediatel call fire department
Suppress ox gen inflow into the chimne and turn off the cooker
Do not put an thing in chimne and look after fire not to extend to the wooden
construction or some other combustible material in vicinit .
NEVER extinguis t e c imney wit water or to pour water in t e cooker
Fire in the chimne ma be extinguished onl with the device with dr powder
Water ma be used onl for surrounding materials
Do not cool surrounding walls with water
Prior to second filling, clean the grid with auxiliar tools to avoid clogging of fresh air
intake.Regularl clean ashtra , taking care top leave enough space for the ash. For
maintenance of necessar nominal power, firebox periodicall is to be filled with
indicated amount of fuel.
Cooker is not intende to work in the mode of continuing burning or heat
accumulation.
Agilit of combustion, as well as amount of heat b the cooker, depend on the
amount of primar combustion air which is to be brought into the area below the grid.
Regulation of primar air amount is achieved automaticall via draft regulator
Rat geber (fig. 7).

Fig. 7
During firing up, turn regulator button into position of maximall open flap in the
direction depicted on fig. 8. During operation, depending on temperature, regulator
flap will open and close automaticall . If lower temperature then set is desired, turn
regulator button in desired position of minimal open flap, then regulator flap is
closed.
Fig. 8
If there are disturbances in burning (weak fuel, non-remedied inaccuracies for proper
operation) use auxiliar regulator, located on front side of ashtra door (fig. 1 pos.
12), and bring some primar air, to improve combustion.
CLEANING AND MAINTENANCE
Regular and proper cleaning enables proper operation and longer life span of the
cooker.
Cleaning of external surfaces – with soft cloth which will not damage the cooker
surfaces. Chemical cleaning agents ma be used and don’t damage surfaces of the
oven. Do not clean colored and enameled surfaces with abrasive agents.
Cleaning of internal surfaces –when clean, use protective gloves.
Clean internal walls of the firebox against deposited smut, collect small and
unburned particles from the grid, clean ashtra and deposited ash within the cooker.
Cleaning of glass surfaces – friebox glass gets dirt during operation. For cleaning,
use soft detergents. Do not use abrasive agents since glass surface ma get
damaged. Clean glass when it’s cold.
Cleaning and maintenance of t e c imney- cleaning and control of the chimne is
recommended at least once a ear as well as after longer inactivit . Regular
maintenance and control of the chimne will prevent origination of fire and weak
operation.
