Electrical connection (Rikatronic3)
The stove is supplied with an approx. 2m long connecting cable with
a Euro-plug. This cable is to be connected to a 230Volt/50Hz socket.
The average electrical power consumption is some 4 Watt in regular
operation. The connection cable must be laid in a way that there is
no contact to any sharp edges or hot surfaces of the stove.

The owner of small firing system or the person authorised for the
small firing system is to keep the technical documentation and is to
submit it to the authorities or the chimney sweep on request.
Note
Please observe the national and European standards as well as
local regulations concerning the installation and operation of
firing installations!
Packaging
Your first impression is important to us!
The packaging of your new stove provides excellent protection
against damage. However damage to the stove and accessories
may still occur during transport.
Note
Therefore please check your stove on receipt for damage and
completeness! Report any deficiencies to your dealer immediately!
Pay particular attention during unpacking that the stone panels
remain intact. Scratches to the material can easily occur. Stone
panels are excluded from the warranty.
The packaging of your new stove is environmentally neutral to a
great extent.
Tip
The wood used in the packaging has not been surface treated and
may therefore be burnt in your stove after removal of all screws
and nails. The cardboard and film (PE) can be disposed of via the
municipal waste collection for recycling.

2. IMPORTANT INFORMATION
General warning and safety information
Observance of the introductory general warning information is
imperative.
QRead the entire manual thoroughly before installing and putting
the stove into service. Observe the national provisions and laws
as well as the regulations and rules applicable locally.
QRIKA stoves should only be installed in rooms with normal humidity
(dry areas according to VDE 0100 Part 200). The furnaces are not
splash water protected and may not be installed in wet areas.
QOnly approved transport equipment with sufficient load carrying
capacity may be used with your heating appliance.
QYour heating appliance is not suitable for use as a ladder or
stationary scaffolding.
QThe burning of fuel releases heat energy that lead to extensive
heating of the stove surfaces, doors, door and operating handles,
glass, flue pipes and possibly the front wall. Refrain from touching
these parts without appropriate protective clothing or equipment
e.g. heat-resistant gloves or means of operation (operating
handle).
QMake your children aware of this particular danger and keep
them away from the stove during heating.
QOnly burn approved heating materials.
QThe combustion or introduction of highly flammable or explosive
materials such as empty spray cans etc. in the combustion
chamber and storing them near the stove is strictly prohibited
due to the danger of explosion.
QNo light or inflammable clothing is to be worn when post-heating.
QUse the heat-resistant gloves supplied to open the doors of your
stove.
QOnly use suitable tools from our range of accessories when
handling embers and make sure that no embers fall out of the
combustion chamber onto inflammable material.
QPush the embers together to form a firebed when you add new
fuel (logs).
QPlacing non-heat resistant objects on the stove or near it is
prohibited.
QDo not place clothing on the stove to dry.
QLaundry racks etc. must be placed at a sufficient distance to the
stove – ACUTE DANGER OF FIRE!
QWhen your stove is burning, the use of highly inflammable and
explosive materials in the same or adjacent rooms is prohibited.
Note
Waste and liquids may not be burnt in the stove!
Note
To prevent your stove from overheating of the internal components,
do never cover the convection fins!
Note
Your stove will expand and contract during the heating and cooling
phase. This can sometimes lead to slight bending or cracking
noises. This is normal and is no reason for a complaint.
First heating
The stove body, just as various steel parts, cast iron parts and the
flue pipes are painted with a heat resistant paint. During the first
heating the paint dries out completely. This may cause a slight smell.
Touching or cleaning the painted surfaces during the curing should
be avoided. The hardening of the paint is finished after the first
heating with high power.
Safety distances
Note
1. To non-combustible objects
a > 40 cm, b > 10 cm
2. To combustible objects and reinforced concrete load-bearing
walls
a > 80 cm, b > 20 cm
Tip
Please observe a minimum distance of 20 cm behind and sideways
the stove for maintenance.

EN
Prior to set up
Floor bearing capacity
Ensure that the substructure is capable of bearing the weight of the
stove prior to set-up.
Note
No modifications may be made to the firing installation. This also
leads to loss of warranty and guarantee.
Floor protection
A glass, sheet steel or ceramic plate is required, if the floor is
combustible (wood, carpet, etc.).
Flue pipe connection
QFlue pipes pose a particular source of hazard regarding gas leaks
and fire. Get the advice of an authorised specialist company for
the layout and assembly.
QPlease observe the corresponding installation guidelines for walls
panelled with wood when connecting your flue pipes to the stove.
QObserve the formation of flue gas (atmospheric inversion) and
draughts when the weather is unfavourable.
QInfeed of too little combustion air can lead to smoke in the rooms
or to flue gas leaks. Hazardous deposits in the stove and chimney
may also occur.
QIf flue gas escapes, let the fire burn out and check whether all the
air inlet openings are free and the flue gas pipes and the stove
pipe are clean. If in doubt notify the master chimney sweep since
draught malfunctions may be connected to your chimney.
Stoves type 1 (BA 1):
QSuitable for multiple occupancy. (Note the different country
regulations.)
QThese may only be operated with the combustion chamber door
closed.
QThe combustion chamber door may only be opened to add fuel
and must then be closed again otherwise other firing installations
connected to the chimney may be endangered.
QThe combustion chamber door is to be kept closed when the
stove is not in operation.
QFouling of the chimney i.e. deposits of highly inflammable
materials such as soot and tar and subsequently fire in the
chimney may occur if wet fuel is used and operation is damped
too much.
QIf this occurs, close the fresh air support (slider,
regulator, flaps - depending on model)! Disconnect
the mains plug at the stoves type Rikatronic.
Phone the fire brigade and get yourself and other residents out
of harm’s way.
Note
on ROOM-AIR DEPENDENT and ROOM-AIR INDEPENDENT
OPERATION:
Your stove has been tested as a room-air independent stove
according to EN 13240 and can be installed as well room-air
dependent and independent.
When installed room-air dependent in combination with room-
air installations (e.g. controlled ventilation and venting systems
(extractors etc.) it must be ensured that the stove and the room
air system are monitored and safeguarded mutually (e.g. via a
differential pressure controller etc.). The combustion air infeed of
approx. 20 m3/h must be ensured.
Please observe the respective local regulations and rules in
consultation with your master chimney sweep. For changes after
the printing of this manual, we can not assume any liability. We
reserve the right to change without notice.

3. BRIEF INFORMATION ON COMBUSTIBLE  LOGS
Suitable fuels and fuel amounts
Your stove is generally suitable for burning dry firewood. You can
also burn combustibles such as wood briquettes.
Note
A stove is not a waste incinerator. The warranty lapses if waste or
non-approved materials such as plastic, treated wood (chipboard),
coals or clothes are burnt! This leads to damage to the stove and
chimney and to environmental pollution!
Note
FUEL AMOUNTS
The stove is fitted with a construction-specific flat firebox. This
means only one layer of logs may be laid on the base embers.
Please observe that adding greater quantities of logs leads to
emission of high temperatures, higher than the stove is designed
for. This may cause damage to your stove. This is reflected in
particular on the glass of the combustion chamber door, which will
get a gray haze in case of overheating the stove, which can not be
removed.
Wood types
Different types of wood have different calorific values. Wood from
deciduous trees is particularly suitable. It burns with a constant
flame and forms long-lasting embers. Coniferous wood has higher
levels of resin and burns off faster as do all softwoods and tends to
spray sparks.

Output controlling
The output of your stove is regulated manually or via the Rikatronic-
control. Please observe that the output of your stove also depends
on the chimney draught and the amount of fuel added.
Clean combustion
1. The firewood must be dry and untreated.
The should-be value is between 14 % and 18 % relative wood moisture.
Wood has to be stored dry and ventilated for 2–3 years.
2. Correct firewood amount and size:
QToo much firewood leads to overheating. This can damage your
stove and increases the exhaust emission values.
QIf you take too little firewood or if the logs you place are too large
the stove will not reach the optimum operating temperature. The
flue gas values also increase in this case.
QFor right quantity of firewood see AMOUNT OF FUEL.

4. INSTALLING THE STOVE
Note
Assembly may only be performed by authorised specialist
companies.
Note
Please observe the regional safety and building regulations. Please
contact your master chimney sweep in this context.
Note
Only use heat-resistant sealing materials as well as corresponding
sealing strips, heat-resistant silicon and rock wool.
Note
Also take care that the flue does not project into the free cross-
section of the chimney.
Note
In case of room-air independent operation the stove pipe
connections must be tightly sealed permanently. Use a heat-proof
silicon to position the stove pipe on the conical supports of the flue
tube nozzles and for insertion in the chimney flue lining.
Note
The stove should not be pushed on unprotected floors.
Tip
Strong corrugated cardboard, cardboard or e.g. old carpet is useful
to assist assembly and as a base. The stove can also be pushed on
this cardboard or carpet.
We recommend original flue pipes from RIKA for proper connection.
Connection to the chimney
QThe device must be connected to a flue that is approved for solid
fuels and is insensitive to moisture. The moisture insensitivity may
vary if the flue calculation results in a dry operation. The chimney
must have a diameter of min. 100 mm for pellet stoves and
130 mm -150 mm for log wood stoves depending on the diameter
of the flue pipes.
QAvoid long flue pipes to the chimney. The horizontal length of the
flue pipe should not exceed 1.5 metres.
QAvoid to many bends of the flue gas pipes. There should not be
more than 3 bends in the exhaust pipe.
QPlease use a connection with a cleaning opening.
QConnections must be made of metal and must meet the
requirements of the standard (install the connections airtight).
QBefore installing a chimney calculation must be made. The
evidence must be performed for single occupancy to EN13384-1
and EN13384-2 for multiple occupancy.
QThe maximum draft of the chimney should not exceed 15 Pa.
QThe derivation of the flue gases must be guaranteed even during
a temporary power outage.
Note
If connecting to multiple connection chimneys and depending on
country regulations, additional safety equipment is required. Your
local chimney sweep will advise you in this case.
Note
Be sure to prevent condensed water from entering via the flue
connection. You may need to have a condensate ring installed -
ask your chimney sweeping expert for more information. Damages
caused by condensate are excluded from manufacturer’s warranty.
Connecting to a steel chimney
The connection must be calculated and shown with EN13384-1
and EN13384-2.
Use only insulated (double) stainless steel tubes (flexible aluminum
or steel tubes are not permitted).
An inspection door for regular inspection and cleaning must be
present.
The flue pipe connection to the chimney has to be air-tight.
Combustion air
Every combustion process requires oxygen from the surrounding air.
This so-called combustion air is removed from the living are in the
case of individual stoves without external air connections.
This air removed must be replaced in the living space. Very tightly
sealed windows and doors in modern flats may mean that too little
air replaces that used. The situation also becomes problematical due
to additional venting in flats (e.g. in the kitchen or WC). If you cannot
feed in external combustion air, then air the room several times a
day to prevent negativce pressure in the room or poor combustion.
Feeding in external combustion air
only for devices which are able to run in room-air independent
operation.
QCombustion air must be fed to the stove from outside via a sealed
pipe for operation independent of the room air. According to
EnEV, it must be possible to shut off the combustion air pipe. The
open/closed setting must be clearly recognisable.
QConnect at the air intake either a pipe Ø 125 mm for log wood and
combi stoves, or Ø 50 mm or Ø 60 mm for pellet stoves. Fix it with
a hose clamp (not included!). At pellet stoves with longer intake
pipes than 1 m the diameter should be increased to 100 mm. (see
RIKA range).
QTo ensure sufficient air intake, the intake pipe should not exceed
max. 4 metres and have max. 3 bends.
QIf the line leads outside it must have a windbreak.
QIn extreme cold pay attention to icing on the air intake opening
(check).
QIt is also possible to suction in combustion air directly from
another sufficiently vented room (e.g. cellar).
QThe combustion air pipe must be tightly connected (adhesive or
cement) permanently to the air nozzles of the stove.
QIf you do not use the stove for a long time, please close the
combustion air intake to prevent the stove from moisture.
Note
Please note that problems may arise due to updrafts in the case
of combustion air supply from an integrated chimney ventilation
shaft. If the combustion air flowing downwards is heated it may
rise and thus counter the chimney with a resistance which in turn
reduces the negative pressure in the combustion chamber. The
chimney manufacturer is to guarantee that the resistance for the
combustion air is a maximum 2 Pa even in the least favourable
operating state of the chimney.
If one or more of these conditions does NOT apply, the result is poor
combustion in the stove and negative pressure in the installation
room.

5. MANUAL OPERATION
Operating the riddle grate
(only stoves with riddle grate)
The ash is moved from the combustion chamber to the ash drawer
by pushing the riddle grate handle back and forth. This frees the way
for the primary air intake which is necessary for heating up.
In general the riddle grate should stay open. The air regulation is
made completely with the control knob at the rear wall.
Combustion air regulation
The control knob for combustion air regulation is situated on the
rear wall.
The performance of your stove also depends on the chimney
draught; therefore the control knob must be used according to your
own experience.
zero setting
0% secondary air
0% primary air
ideal position
33-66%secondary air
0% primary air
middle position
100% secondary air
0% primary air
Heating-up position
100% secondary air
100% primary air
The “Heating-up position“ may only be used for heating up.
Note
The air control seals to 100%. Complete closing of the air regulator
(zero setting of control knob) during operation poses a hazard of
deflagration and is strictly prohibited.
A stop to prevent inadvertent closing of the air intake has been
integrated for safety reasons.
If the stove is not in use, warm air can release through the chimney.
The Zero position of the control knob can prevent this. To prevent air
intake completely, the control knob must be pressed back slightly,
only then the zero position can be set and the air regulator thus be
closed.
Note
Sometimes a lot of smoke develops when wood is placed on a
low firebed or when there is too less fresh air for combustion. An
explosive gas/air mixture may arise and cause an eventual heavy
deflagration. For safety reasons it is recommended to leave the
combustion chamber door closed and press the control knob at
the rear wall down completely into “heating-up position”. If the
log wood is not igniting, start a new heating-up procedure after it
stopped smoking.
Correct heating up
1. Press the control knob down into “Heating-up position” – primary
and secondary air intakes are opened completely. Open the
combustion chamber door and sweep the ashes into the ashtray.
Then open the riddle grate completely (only stoves with riddle grate).
Place 2 small pieces of chipboard lengthways left and right in the
bottom of the combustion chamber.
Place 2 logs crossways on top of this chipboard.
2. Now place further pieces of chipboard in crosswise layers on top of
the logs and place 2-4 ribs of the RIKA-firelighter on the left on top of
the chipboard.Some uncoated paper can be placed underneath the
chipboard in case there is no firelighter available.
3. Now light the firelighter (or the uncoated paper) and close
the combustion chamber door. “Correct heating up” primarily
counteracts excessive smoke.
If the combustible is well lit, set the control knob to middle position
some minutes later. The primary air intake is now closed and the
secondary air intake is completely open. The control knob can be
set to ideal position (see COMBUSTION AIR REGULATION) another
few minutes later (depending on draught and fuel quality / amount).
After the first burn-off, again add 2 logs (see AMOUNT OF FUEL). Set
the control knob to “Heating-up position” again until the wood is well
lit. Further regulation is effected as described in Item 3.
Please proceed in the same way for every further addition of wood.

6. OPERATION  RIKATRONIC3
Note
For stoves with RIKATRONIC3 System (electronic
air flap control) a flue pipe with optional “lockable
damper flap” must be always open during heating!
RISK OF FIRE!
Operating the riddle grate
(only stoves with riddle grate)
The ash is moved from the combustion chamber to the ash drawer
by pushing the riddle grate handle back and forth. This frees the way
for the primary air intake which is necessary for heating up.
In general the riddle grate should stay open.
RIKA firelighter
Always ignite the RIKA firelighter on the red tip. One block consists
out of 8 ribs which can be divided to the desired size. The amount
of RIKA firelighters also depends on the size and humidity of your
firewood. Ideally, one rib is enough to light up the fire.
Tip
You can order the RIKA firelighter with the number E15834 at your
RIKA dealer.
Heating instructions
Preparation
Plug in the mains plug and activate the main switch at the rear of
the stove. The main switch now lights up green. The display at the
front of the stove also lights up green for approx. 10 secs. and then
flashes intermittently red until the air flap motor reference run has
been completed.
Correct heating up
One the reference run has been completed and the display is
constantly red, open the combustion chamber door and sweep
the ashes into the ashtray. Place left and right 2 small pieces of
chipboard lengthways in the bottom of the combustion chamber
and open the riddle grate completely.
Place 2 – 3 smaller (highly flammable) logs crossways on top of this
chipboard.
Now place further pieces of chipboard in crossways layers on top of
the logs and ideally you should place 2-4 ribs of the RIKA-firelighter
on top of the chipboard. Some uncoated paper can be placed
underneath the chipboard in case there is no firelighter available.
Now light the firelighter (or the uncoated paper) and close the
combustion chamber door. Correct heating up primarily counteracts
excessive smoke during heating up.
Heating up
Fill amount for heating up: 2 - 3 logs of max. total 2.5kg
As soon as the combustion chamber temperature exceeds 80°C,
the display changes to green (if the display does not change to
green within 10 min of closing the combustion chamber door, then
the heating up procedure has failed, i.e. the required combustion
chamber temperature of 80°C was not exceeded).
Once the display has changed to green, the burn-off control of
the heating-up starts. The heating-up phase takes approx. 60 min
depending on the temperature and fill amount. This time is required
to obtain a suitable bed of embers.
The display changing from green to red flashing indicates the right
time to add wood.

14
Adding wood
Fill amount for heating up: 2 logs of max. total 2.5kg, depending on
requirements.
The red flashing phase varies depending on the ambient influences
between 5 and 10 min. If the combustion chamber door is opened,
the display changes to green flashing.
If the temperature increase is sufficient (wood added and lit), the
display changes to constantly green (the RIKATRONIC3starts the
burn-off control).
If an increase in temperature in not detected, the display changes,
depending on combustion chamber temperature, to the status prior
to adding wood, either to red flashing or to constantly red.
Burn out
If no more wood is added during the red flashing phase, the display
changes to constantly red. No more logs may be added from this
point since ignition of any logs added cannot be ensured. The stove
must be heated up again.
ECO operation
If the room to be heated and the stove are already at temperature,
continued operation with lower heat output and log addition is
possible.
Fill amount in ECO operation: 2 logs in total approx. 1.5kg
If the Eco key is pressed when adding wood (after closing the
combustion chamber door), the display changes to yellow flashing
and Eco operation is activated.
This operating mode also regulates the burn off with lower heat
output to the optimum.
If the Eco key is pressed again or the combustion chamber door is
opened, the display changes from yellow back to green and normal
operation is activated again.
Complete closing of the air flaps
The RIKATRONIC3has a safety device that prevents the air flaps
closing completely during heating operation (hazard of deflagration).
However the air flaps can be closed completely with a sequence of
ECO key and opening and closing the combustion chamber door to
stop the existing draught on stove standstill.
QEnsure that the stove has cooled down, is switched off and that
the combustion chamber door is closed
QPlug in the mains plug and activate the main switch at the rear
of the stove
QWait until the reference run has been completed and the display
lamp is constantly red
QNow depress the ECO key for 5 sec with the combustion chamber
door closed until the display changes to yellow flashing
QOpen and close the combustion chamber door, the display is now
constantly yellow
QThe depress the Eco key again for 5 sec until a click is heard and
the air flaps close completely
As soon as the air flaps reach end position, the display goes off and
the stove can be switched off and the mains plug disconnected.
Power failure
In the event of a power failure the air regulation flap remains
unchanged until the fire goes out (no display). If mains voltage is
available again after a brief power failure, the display lights up as
on start for 10 sec green and then changes to red flashing due to the
repeat reference run of the air flap motor.
If the temperature of the stove is still more than 80°C, the display
changes and the control system changes to the respective status.
If the stove cools back down during the power failure, the display
changes to constantly red
Manual regulation
Note
Manual operation may only be performed with the unit switched off.
Any other procedure than that stated below may cause damage to
components and inevitably leads to loss of warranty.
QSwitch the stove off at the main switch and disconnect the mains
plug.
QInsert the socket spanner supplied sufficiently far into the sleeve
as shown.
Turning clockwise opens the air flaps; anti-clockwise closes them.
QTurn the socket spanner first to heating-up position (open until a
stop is detected).
QTurn the socket spanner gradually anti-clockwise after the
heating-up phase to control the air intake and thus the burn-off
manually.
Note
Always ensure that the stove is supplied with sufficient air for
combustion; otherwise increased smoke development may occur.

7. MAINTENANCE AND CLEANING
Basic information
Note
Your stove must be switched off and cooled before any
maintenance work is performed. Ensure that you do not vacuum
into the combustion air line during heating operation during any
cleaning (vacuuming). You could vacuum out embers – FIRE RISK!
Note
Only work on the unit when the mains plug has been disconnected.
The stove should be cleaned thoroughly prior to the start of the
heating season to prevent excess odour.
The frequency with which the stove requires cleaning and the
maintenance intervals depend on the fuel you use. High moisture
content, ash, dust and chips may more than double the maintenance
required. Only use wood that has been stored properly and ist dry
and untreated.
Note
Ash may contain embers – only place ash in sheet steel containers.
FIRE RISK! In a cold state, dispose it of in the household waste.
Empty the ash drawer
Empty the ash drawer regularly. The ash drawer is simply pulled
forward with the combustion chamber door open
Checking the door contact
(Only for models with Rikatronic)
Check that the door contact switch is working at regular intervals.
Press the door contact several times with your hand to prevent it
from sticking.
Cleaning the door glass
The glass can be cleaned best with a moist cloth. Stubborn dirt can
be removed with a special cleaner (free from corrosive acids and
solvents - otherwise there is a risk of damage to the glass surface)
available from your stove dealer.
Note
Never use abrasive or aggressive cleaning agents to clean the
wooden door handle, these will damage the wood.
Checking door seal
The condition of the seals at doors and glass should be checked at
least 1 x per year. Repair or replace seals depending on condition.
Note
Only intact seals ensure your stove works perfectly.
Cleaning of painted surfaces
Wipe of the painted surfaces with a damp cloth, do not scrub. Do not
use solvent-containing cleaners.
Cleaning the flame temperature sensor
(only type Rikatronic3)
Remove the dust deposits from the sensor at regular intervals. Use a
clean cleaning cloth or newspaper.
Combustion air - air intake
Also clean the air intake if necessary.
Note
Only when the stove is cold and not running!
Cleaning the flue gas channels
(1 x annually)
Remove the flue pipes. Inspect and clean chimney connection. Brush
off any soot and dust deposits in the fire and in the flue pipes and
vacuum.
Note
Accumulated fly ash in the flue gas channels may impair the
performance of the stove and pose a safety risk.
