Fuel
The appliance is designed for combustion of solid fuel:
- recommended fuel is wood (max diameter 190 mm, max length 450 mm)
- the appliance also enables burning of other kinds of solid fuel (wood briquettes, waste wood,
brown coal briquettes, brown coal blocks 40 mm) However the operating conditions and
parameters of the appliance may differ from those with the recommended fuel Please note that
the technical characteristics given above were based on a test wood fuel sample and using other
fuel types will alter these characteristics, energy output, fuel consumption, flue draught etc
Make sure that the fuel is dry It is not recommended to burn high-calorific fuels, which reduce the
service life of the appliance
Grate, Grating
The purpose of the grate is allowing the burned fuel to fall to the ashtray, which increases the
supply of combustion (primary) air to the combustion chamber It is done by means of the poker
with the combustion chamber door open
After the end of each operation (and cooling down) it is possible to grip the grate lever to move the
grate back and forth To remove the pieces which are too big to fall through, rotate the grate a few
times by means of this lever
Air Supply C ntr l
Controlling the supply of primary combustion air is enabled by means of the air rose, which is a
part of the ashtray door Turning the rose by means of the rose handle enables precise control of
air to the combustion chamber and thus alters the speed of fuel combustion (energy output of the
appliance)
The secondary combustion air supply can be controlled by means of a lever on the front part of
the appliance (Drawing 1, point 13) Air supply is opened (flap is opened) by movement of the
lever towards to the front side of appliance and it is closed (the flap is closed) by movement from
the front side Movements lock on the lever by neck
During the operation of the appliance the supply of the combustion air must be maintained, the air
supply inlet must not become blocked Mechanical ventilation/ air extraction must not be used in
the room where the appliance is placed, unless there is provided sufficient air supply for
ventilation Ventilation levels are provided in your local building regulations It is advised to check
ventilation issues with your local building control office to ensure trouble free operation
The Ash Extracting D r (Drawing 1, p int 6 – Sweeping d r)
When the cooker has been in operation for some time, soot will collect in the cooker parts of the
draught system (especially where coal has been used) This will eventually affect the draught and
may create problems while lighting the fire It will also make operation of the cooker less
economical, especially when cooking in the oven
In the course of cleaning take off the hob top plates, then remove the soot first from the sides
of the oven walls Clean all the removed deposits through the ash extracting slot situated under
the oven door This can be done simply by using damp newspaper, for example

Appliance h b-t p panel (variants)
1) The standards panel consists of two parts (Drawing 2):
Plate I – a cast iron range hob with a round removable centre plate located directly under
the fire box This plate is meant for fast cooking
Plate II – a steel hob is located above the oven This plate maintains a lower temperature
and thus can be used for slower cooking, simmering and keeping food warm
2) The single-piece ground steel finish hob-top panel
3) The single-piece glass and ceramic panel
You should always use pots with flat bases
Drawing 2
Igniti n Flap (Drawing 3)
Is placed below the range and controlled by means of the lever located at the rear of the range
frame It has the following operating modes:
Open position – Ignition and
intensive cooking
throughout the entire range area I +II
(Flap open)
Closed position – Baking in the oven and
Cooking on the Plate I
(Flap closed)
Drawing 3
Following ignition, after the fire has caught, close the ignition flap and operate the appliance with
the ignition flap closed This will influence the flow of flue-gas and increase the efficiency of the
appliance

TYPE 9112-HEU 07/2014 7
When you are firing the appliance for the first time, ensure sufficient ventilation of the room, until
the protective coatings have completely burned off Once satisfied that that the coatings are no
longer present the cooker is safe to use for the purpose of cooking food
Before ignition open the furnace door and check if the grate is clean Take twists of paper, lay out
tiny chips of dry soft wood on it, then lay larger pieces of dry wood on the chips and then light the
paper Special matches are available to carry out this operation at a distance from the flame
Before ignition open the ignition flap (Drawing 3) Open the air supply under the grate through the
air rose to the maximum and also the secondary air supply
The c ker cann t be used with ut a water pump c nnected t the d mestic central
heating system t prevent damage t the heat exchanger caused by verheating. The
pump sh uld be already in perati n when starting the fire!!!
After the fuel is ignited close the combustion chamber door and when the fuel burns through,
stoke up After a layer of burning embers is formed you can add more fuel in batches Make sure
not to extinguish the fire by adding excessive amounts of fuel too quickly
Gradually prolong the intervals of stoking, so that the final interval is once an hour The average
fuel consumption is 3 – 4 kg of fuel per hour Adding of fuel shall be done manually or by means of
a suitable shovel Full combustion can be visually easily checked: no heavy smoke can be seen
rising from the chimney (except the time immediately after stoking up)
If you add half the amount of fuel every thirty minutes and perform grating at the same time, the
combustion performance will improve
The appliance output can be controlled by the supply of air under the grate and by the amount
and type of fuel When operating the appliance at the rated thermal output and burning wood, the
primary air supply shall be opened to approx 20 %, the secondary air supply closed From time to
time clean the grate by means of the poker If the appliance emits smoke into the room during
stoking up, close the air supply Do not overheat the appliance by too intensive stoking up and
grating!
The entire combustion chamber can be filled with fuel Make sure that the fuel does not fall out of
the combustion chamber during stoking up In case of bad draught or weather conditions use
smaller wood logs
Recommendations for setting of stabilisation operation:
Lay a wood log of 190 mm diameter and 450 mm length on the bottom burning layer Close both
the primary and secondary air supply With these settings the appliance should keep burning for
up to 3 hours
C king n the Appliance H b T p
The range above the combustion chamber is designed for fast cooking With the described set
operation, 2 litres of water in a pot with flat bottom of a diameter of 180 cm with a lid should start
boiling in 15 minutes
During cooking watch out for boiling over If it happens, remove as much of the spillage
immediately and when finished cooking clean the remainder using a damp towel, detergent and
finally using a dry towel If the dirt bakes in, it is more difficult to remove later From time to time
(depending on the frequency of operation) wipe the range down with vegetable oil
In the area above the oven the range has a lower temperature - this part of the range is suitable
for slow cooking and for keeping food war Use pots with a flat bottom for best results

Baking and R asting
If you want to bake in the appliance, the oven has to be sufficiently heated and thermally
stabilised Use smaller dry logs for fast firing of the oven Set the ignition flap to the “baking”
position
A typical baking temperature is reached in approx 15 minutes However, we recommend that you
start baking after half an hour to an hour, when the appliance is warmed-through evenly and the
temperature in the oven is stable and even
For roasting of joints of meat we recommend achieving a stabilised temperature indication on the
oven door thermometer between 170°C and 200°C A typical roasting time would be 1 ½ to 2
hours
For baking pastry and cakes we recommend the temperature indicator on the oven door is
stabilised between 140°C and 180°C The time of baking is typically from 20 to 40 minutes
To ensure even baking/ roasting we recommend turning the tray around halfway through the
cooking process
If you want to reduce the intensity of baking (e g for drying of fruits), use an empty tray as a shield
form below or from above
When taking out the tray with food, you must not lay it on the cooking range hob The temperature
of the cooking range hob is much higher than that of the oven and the food could easily boil over
or burn We also do not recommend laying the tray with food on the open oven door
The baking accessory of the appliance is designed for short-time contact with food The short-time
contact should not exceed 4 hours for drinks and 48 hours for food of solid or pasty consistence
The Heat Exchange Unit
The range cooker with built-in heat exchange unit demands more user attention than a standard
cooker or a typical boiler as it requires a more regular supply of solid fuel into the burner, as well
as regular poking/stirring of firebox grates It is not possible to fix a stable temperature level
We recommend connection of this model to a maximum of two metal radiators, each up to 1200
mm in length and a heating water tank of 60 litres capacity Before installation each radiator
should be fitted with an isolation valve
Due to the considerably low capacity (9-12 kW) of this model in addition to the variable operating
conditions such as fuel type, chimney draught, ambient temperatures etc , we rec mmend the
f ll wing :
- Only one heating device (one radiator or heating water tank) should be turned on during the
kindling process The remainder of the devices can be introducer later
- In case of long time baking in the oven only one heating device must be turned on and adding
the fuel at 30 minute intervals
-
During the summer setting at least one heating device should be switched on, for example, a
heating water tank (as there sh uld be water in the heat-exchange unit)
The heat exchange unit incorporated into the range cooker is necessarily of a compact size and
has limited water capacity We recommend that the unit is only connected to a pumped water feed
with a thermostat rated at 45°C If the thermostat exceeds the recommended water temperature,
this is likely to cause heat damage
N te: F r the purp se f taking surplus heat fr m the heat exchange unit, we rec mmend
t use additi nal heating device.

Cleaning f the Furnace and Flue Paths
To maintain optimum, problem-free performance of the appliance it is necessary to clean it
regularly Cleaning of the fire box must always be done with the appliance out of operation
If igniting the combustion chamber after a longer interruption of operation, it is necessary to check
that flue paths, flue ducts and chimneys are not blocked and no obstructions are present Regular
maintenance should be carried out once a year by a service engineer
Remove unburned remnants from the grate by means of the trowel and poker To drop larger
pieces of unburned fuel to the ashtray, pull out the grate lever and turn it to the right Cleaning of
the inner walls of the appliance (draught system) and inner housing of the oven shall be done as
follows:
Remove the range hob to get access to the dirty surfaces inside, from which you can sweep the
soot easily down to the bottom of the appliance From there you can sweep them into the ashtray
through the sweeping hole Once clean put the range hob back ensuring that individual parts fit
tightly and seal perfectly
Outer surfaces cleaning
Clean the appliance after cooling
• Enamelled surfaces should be cleaned with a damp cloth or sponge, and then polished to
dryness With higher pollution you can use detergents
• It is important to protect the hob from water to avoid corrosion Clean them only when they
are dry If you use a damp cloth with detergent when cleaning the hob, the hob should be
dried when finished From time to time we recommend greasing the hob with a thin layer of
vegetable fat
• During oven cleaning, do not use sharp objects to remove food waste Moisten them before
removing with a brush and wiping with a cloth, or alternatively, a suitable cleaning agent for
the removal of heavy impurities and accretions may be used
The appliance cannot be lit: -inspect the flue ways, flue gas duct and chimney
-check the Ignition flap, circular air grid, fire place door and ash
tray
Overheated appliance -put out of service, do not stoke, close the air grid, let fire burn
out
Fire in the chimney -do not use water to extinguish the fire
-close all of the air intakes, cover the chimney if possible
-contact a qualified chimney sweep service
-contact the manufacturer or your supplier
