DESCRIPTION OF THE APPLIANCE AND ITS PARTS
Type VSP-9106 is designed for burning solid fuel (wood, wood briquettes) in periodic
batches for the purpose of home cooking and domestic central heating system,
currently according to CSN EN 12815:2002 and Amendment A1:2005. The appliance
can be connected to the flue only from the rear side. A permanent heating operation
cannot be set and the fuel must be added with the interval of 1-3 hours (i.e. The
appliance is suitable for short operational periods only).
Rooms are heated by radiant heat flowing into the space through the front section,
the hob and the sides. The built-in hot-water exchanger is able to heat the other
rooms using radiators, or to heat the water in a hot-water tank. The hob top is
designed for cooking and the whole surface is heated during operation.
FIRE BOX
The firebox consists of the heat exchanger proper (welded unit with fins), a bearing in
which the grates (sliding, suspended) are located, and a cast iron panel with holes for
the supply of secondary air. The horizontal sliding grating is controlled by moving the
grating lever back and forth, see the Drawing 6. The grating is only moved for cleaning
purposes. By moving it forward, a flow-through hole is formed at the back of the fire
box through which the unburnt fuel residues fall into the ashtray, see the Drawing 3.
During operation, the sliding grating must be fully retracted back, see the Drawing
2; grating is not allowed otherwise the burning fuel could get stuck in the hole!
Drawing 2 Drawing 3
During heating, it is recommended that the fuel is poked from time to time using a
poker to increase the supply of primary combustion air to the fire box. The grating in
the front part of the fire box improves combustion and also serves to improve

cleaning of the burnt fuel, see the Drawing 4. The cast iron plate with holes supplies
the secondary air to the fire box, which guarantees better combustion, see the
Drawing 5.
Drawing 4 Drawing 5 Drawing 6
A cleaning flap is located under the hob top in the back top part of the appliance,
which is removed only for cleaning purposes. During operation, the flap must be
always fully retracted, see the Drawing 7. When the flue gas routes are cleaned,
hold the flap behind the bend and remove it completely, see the Drawing 8.
Drawing 7 Drawing 8
AIR INTAKE REGULATION
The primary air intake regulation is controlled using a combustion air intake control
built in into the ash door, see the Drawing 1, point 5. The air intake can be controlled
by turning the regulator handle, see the Drawing , point 6, to adjust the fuel
combustion speed and appliance performance. The regulation is indicated by
triangles on the ash door (Drawing 9), where the lever positioned under one triangle
means that the air intake is closed for slow burning. On the other hand, in the
position under four triangles the air intake is fully open for fast burning.

Drawing 9 Drawing 10
During the operation of the appliance, the primary combustion air supply must be
ensured to the room in which the appliance is located. We do not recommend to use
air (vapour) suction devices unless the sufficient air supply for burning in the
appliance is provided.
The supply of secondary air flows into the fire box through a cast iron plate with
holes suspended in the back part of the fire box (Drawing 5) and through the fire box
door - a vent in the bottom part of the door heat shield. Secondary air flow cannot be
regulated.
TEMPERATURE GAUGE

APPLIANCE INSTALLATION
All the local regulations including regulations concerning national and European
standards must be observed during installation of the appliance. The appliance for
solid fuel is intended to be used in the domestic environment. A sufficient supply of
the air necessary for burning must be provided in the room where the appliance is
installed. Do not use air suction devices unless the sufficient air supply for burning in
the appliance is provided.
The necessary condition of the proper operation is a stack with a sufficient draught.
The chimney draft requirements are specified in the technical parameters. It is
recommend to use a chimney with the inner diameter of at least 160 mm and the
min. height of 5 m from the connection to the flue collar. The appliance must be
connected to a separate chimney.
Upon delivery, the appliance is ready to be connected to the household chimney
using a connecting link. The connection to the chimney must comply with the
applicable standards; it should be as short as possible, straight and the connections
must be tight. The appliance does not include a chimney flap; therefore, it is
necessary to connect the appliance to the flue ducting with the chimney flap,
Drawing 15. Install the appliance to ensure adequate access for cleaning the flue
ducting and the chimney. The appliance may only be installed by
authorized persons.
The connection must comply with the national, European, local and
building regulations as well as the fire protection provisions. The
chimney inspection report must be available.
Ensure sufficient access to the chimney and the flue ducting; clean the
appliance several times a year during the operation according to the
applicable regulations. If regular inspection and chimney cleaning are
omitted, the probability of a fire in the chimney increases.

B, C1, C2, is at least 800 mm in the direction perpendicular to the opening wall, 400
mm from side and 400 mm from behind, Drawing 17. For combustible materials with
the combustibility grade C3and with the unknown combustibility grade, the distance
must be doubled. No flammable objects should be laid on the appliance and should
be kept at a safe distance from it. The appliance must stand on a non-combustible,
heat-insulated mat with the dimensions exceeding the section plan by at least 600
mm in front of the stoke hole and at least 300 mm from the sides of the stoke hole.
During heating, the heat energy is released, which leads to a noticeable heating of
the entire appliance.
Indication of areas where burns may occur:
Hob and hob frame, sidewall
Fire box door and ash door
Control handles
Flue ducting
Make your children aware of the risk of burns!

INSTALLATION IN THE HOT-WATER SYSTEM
• The appliance and the exchanger may only be installed by a person authorised to
do so. The correct connection is the responsibility of the performing company or the
user. The appliance with a heat exchanger cannot be operated without heating
medium. The appliance claims caused by unprofessional interventions shall not be
accepted.
Observe the following instructions and recommendations during assembly and
operation:
• Level the appliance.
• Connect the heater exchanger heating and return water connections to the hot-
water system according to the diagram, Drawing 19.
• Due to the limited space of the appliance design, the water-water heat exchanger
dimensions are smaller with a smaller water volume. It is recommended to connect
to the circuit with forced water circulation, i.e. with a pump. Install the pump in the
return water line. In case of power failure, provide a pump drive backup power
supply, otherwise it will be necessary to stop the combustion in the appliance!!
• Connect the 1.8 bar / 3/4” relief valve to the system.
• As close as possible to the outlet from the exchanger, mount the pump
temperature sensor and set the pump switching temperature in the range 65-70°C.
Lower outlet temperature (with respect to a smaller exchanger volume) could cause
insufficient heating of the system.
• It is recommended to set the temperature gradient of 65°C to 55°C or 70°C to 60°C.
• It is recommended to connect two or three heating bodies (radiators) with the
length of 1,200 mm each, and a boiler with the volume of 80-100 l. When connected,
install the valves on each body.
• The entire heating system can be heated simultaneously. If the return water
temperature of at least 55°C is not reached, open the heaters one after another until
the sufficient return water temperature is reached.
• If the radiators are fitted with thermostatic heads, a heat accumulating tank
should be connected to the system.

OPERATION AND CONTROL
Before firing the cooker for the first time
Remove the hob, route the packing rope all around the perimeter inside the
frame of the hob and seat the hob back.
The cleaning flap under the hob must be fully pushed towards the rear wall.
Ensure adequate ventilation of the room as protective paint, grease residues
and other materials will be baked.
Check that the grate is clean and in the correct position, i.e. retracted
backwards.
Put a piece of newspaper on the grate, spread small dry softwood chips on
the paper and a few pieces of smaller logs. To facilitate ignition, insert a
piece of paper in the stake hole.
Open the primary air intake on the ash door to the position for the maximum
flow. In case of worse draught conditions, the ignition may be performed
with the ash door slightly open. During further operation, the door must be
closed and the air intake is regulated only using the combustion air intake
control.
It is recommended to use long matches, dry wood chips or a solid fire lighter
for ignition. When the fuel is ignited, close the fire box door.
Once a glowing mat is formed, you can add more fuel.
Set the pump switching temperature in the range of 65 –70°C, open all
radiators or a boiler. When the temperature of the water in the exchanger
reaches the required temperature, the pump is switched on to distribute the
hot water to the radiators. The return water temperature should not drop
below 55°C, otherwise tarring and low temperature corrosion may occur. In
this case, leave the nearest radiator open and close the others. After
reaching the required return water temperature of 55°C, open the radiators
one after another.
Make sure that you do not smother the fire by adding the fuel too fast. Gradually
extend the fuel feed interval. Add the fuel manually. During the first week of use, you
must not overfill the fire box with fuel (up to a maximum of half the fire box height).
Any heat treatment of food is prohibited during the first heating since all parts of the
appliance are baked and the sheets of the skeleton are annealed when the appliance
is running in. Avoid fast heating of the appliance with the excessive load. If the above
conditions are not observed, parts of the appliance may be damaged. Easy visual
check of combustion - no heavy smoke can be seen rising from the chimney (except
the time immediately after stoking up). The capacity of the appliance is regulated by
the amount of fuel added and by the amount of primary air intake under the grate.
Occasionally clean the grate with help of a poker.

Normal operation
Once the appliance is run-in, proceed as in the case of the first heating. The entire
fire box may be used for combustion; a larger amount of fuel may be added
gradually, until the fuel starts falling from the stoke door. If the appliance emits
smoke after the fuel is added, close the primary air intake on the ash door. Open the
stoke door partially to suck the air and only then fully open it and load the fuel. By
loading a larger amount of fuel, you can extend the feeding interval depending on
the type and amount of the fuel. Always make sure that you do not smother the fire
by adding the fuel. During heating, use a poker for grating to support burning.
Cooking on the cooking range hob
The cooking range hob is heated on the entire surface for all the time the appliance is
heated. The temperature of the hob top is influenced by the amount of fuel added
and the air supplied. When overboiling occurs during cooking, it is recommended to
remove larger impurities immediately so that they are not burnt on the hob, and
remove the remaining impurities upon the hob cools down. You should always use
pots with flat bases and metal handles.
CLEANING AND MAINTENANCE
The workmanship quality of the appliance guarantees a long service life, but without
proper operation and maintenance, this lifetime would be difficult to reach. Clean
the entire appliance, the flue ducting and the chimney on a regular basis. Check that
the parts of the appliance and the flue ducting for defects. Cleaning and maintenance
should always be carried out with an appliance completely cooled. After a longer
period of non-operation, perform a preventive inspection of the throughput of the
flue gas routes of the appliance, the flue ducting and the chimney.
