The owner of small firing systems 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. The cardboard and film (PE) can be disposed
of via the municipal waste collection for recycling.
Electrical connection
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 about 20 Watt in heating operation. And approx. 150
Watt during automatic ignition. The connection cable must be laid so that there
is no contact to any sharp edges or hot surfaces of the stove.

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.
QPellet stoves are generally designed and developed to operate as an
additional heat source (supplementary heating). The cleaning, as well as the
information about the wear are set accordingly in our manual. If the stove is
heated in continuous operation, the cleaning intervals are shorter. Increased
wear, especially of the thermally stressed parts, is the result. Please
therefore strictly follow the requirements for cleaning and maintenance!
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
CAUTION when filling the pellet container. The opening of the pellet container
is sufficiently dimensioned to ensure easy filling. Take great care that no
pellets drop to the convection fins and the hot stove body. This can cause a
lot of smoke.
Tip
Therefore we recommend refilling the pellet container at a cold stove.
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.

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 base is required (glass, sheet steel or ceramic) 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):
QThese may only be operated with the combustion chamber door closed.
QSuitable for multiple occupancy. (note the different country regulations)
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 the chimney
is miscalculated and dimensioned wrong and if wet wood is used.
If fire in the chimney occurs, disconnect the mains plug of the stove. Phone the
fire brigade and get yourself and other residents out of harm’s way.
Note
Due to the size of the combustion chamber door it is necessary not to
open the door abruptly, to prevent the flames coming out. Especially when
reheating into blazing flames.
Note
on ROOM-AIR DEPENDENT and
ROOM-AIR INDEPENDENT OPERATION:
Your stove has been tested as a room-air dependent stove according to EN
13240 and does not conform in Germany to the requirements for room-
air independent operation. 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

3. BRIEF INFORMATION ON FUEL - PELLETS
What are pellets?
Wood pellets are a standardised fuel. Every manufacturer must adhere to certain
conditions in order to enable flawless, energy-efficient heating. Pellets are made
from wooden waste, from sawmills and planning workshops, as well as from
residue from forestry operations. These “starting products” are crushed, dried,
and pressed into Pellet “Fuel” without any bonding agent.
ENplus – Pellets
This new pellets are a standard sets new benchmarks in the European pellet
market. The traceability of pellets is ensured thanks to the use of identification
numbers. The pellet manufacturers’ production facilities and manufacturing
processes are reviewed every year. A quality assurance system ensures
the pellets comply with the requirements of the new standard and that the
conditions for trouble-free heating are guaranteed

Your pellet stove is only approved for the burning of pellets of tested quality.
Please ask your pellet stove dealer for tested fuel and a list of monitored fuel
manufacturers.
Note
Only burn pellets that have been inspected according to ÖNORM, DIN Plus
or ENplus-A1. Using poor quality or prohibited pellet fuel will have a negative
effect on the function of your pellet stove and can also lead to the warranty
becoming null and void, as well as the product liability connected with this.
Note
Burning straw, maize, woodchips etc. is not permitted! Observe waste
incineration legislation! Non-observance of these regulations makes void all
warranty and guarantee claims and may impair the safety of the unit!
Pellet container refilling during operation
Note
CAUTION when filling! Avoid direct contact between the plastic bag and the
hot stove. Immediately remove all pellets that have fallen on the hot stove or
next to the container!
We recommend always having a suitable amount of pellets in the container
to prevent the fire from extinguishing due to a lack of fuel. Check the level
frequently. However the container lid should be kept closed, except during
filling.
If you refill the container during operation (open the container lid), the fan will
speed up and the pellet auger will stop; operation will only be continued once
the container lid is closed again (see WARNING AND ERROR MESSAGES)
Pellet container capacity (see Technical Data).
Pellet storage
In order to guarantee problem free burning of the wooden pellets, it is imperative
necessary to store the fuel as dry as possible and free from impurities.
Pellets should not be kept in sacks outdoors or stored in a manner where
they are exposed to the environment. This can lead to blockages in the screw
conveyor.
Note
“Screw stoppers” are excluded from the warranty.

4. 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.
Guide value between 14% and 18% relative wood moisture.
Wood stored dry and ventilated for 2 – 3 years.
2. Correct firewood amount and size
QToo much firewood leads to overheating. This stresses the material too
much and leads to poor exhaust emission values.
QToo little firewood or logs being too large means the stove does not reach
optimum operating temperature. The flue gas values are also poor in this
case.
QFor right quantity of firewood (see AMOUNT OF FUEL)

5. TECHNOLOGY AND SAFETY FUNCTIONS
The technological advances in your new combi stove are the result of years of
testing and practical experience. The practical advantages of your pellet/log
stove are convincing:
QAutomatically regulated pellet operation
QAutomatically regulated log operation
QCurrentless log operation (manual regulation)
The range of operating modes leaves nothing to be desired. The automatic fuel
detection means the operating mode can be changed at any time (simply add
logs during pellet operation or ignite logs with the pellet burner).
Manually regulated currentless log operation is also possible. This ensures
faultless operation even in the case of longer power cuts.
Operating comfort
The microprocessor-controlled combustion regulation optimises the interaction
of flue gas blower, air flap position and screw using the current combustion
chamber temperature. This guarantees optimum combustion and operating
status in both pellet and log operation.
All function can be regulated centrally using the integrated touch display. The
intuitive graphic interface permits easy operation; all the settings can be made
quickly and simply.
Top efficiency - lowest emissions
A very great heat exchange surface together with optimum combustion air
control leads to excellent fuel utilisation.
Fine continuous pellet dosing in an optimised burner pot made of high-quality
grey cast iron leads to virtually complete combustion with very good exhaust
gas values - and this is guaranteed in every operating phase.
The combination of temperature-controlled automatic air regulation and
optimised wood retainer geometry enable combustion with minimum emissions
at top efficiency in log operation.
Note
The automatic control system means that during operation, the flame noise,
pellets dropping and actuation of the electronic components permissible for
living spaces are audible.
Note
The innovative technology of our combination stove INDUO offers you a
maximum of heating comfort, depending on the availability of the fuel the
stove can be heated with pellets and / or logs without any modification.
Both cases are solid fuels that can cause a fogging of the door glass during
the combustion, particularly with the very fine ash from wood pellets.
By external influences such as chimney draft or pellet quality this coating can
be very bright or dark black (especially with low power ). This is a natural
process and is not a shortage.
We therefore recommend regular cleaning of the door glass, just because
soot is an excellent insulator and thus the heat dissipation can be reduced.
If the stove is heated according to its function in the combined operation, a
significant improvement can be achieved due to the higher temperatures in
log wood mode.
Burnback and flue gas flaps
The combi stove safety concept is based on double safeguards. If faultless
operation is no longer ensured due to a component defect or power cut,
the burnback flap in the pellet chute is released. This directly interrupts the
connection between the pellet container and push in screw. Thus preventing
pellet burnback. Closing the burnback flap at the same time opens the flue gas
flap thus ensuring safe burning off of the fuel in the combustion chamber.
Note
Check with every maintenance / cleaning the correct operation of the flue
flaps.
Overheating
A safety temperature limiter (STL) switches the stove off automatically on
overheating. Once the stove has cooled, the STB at the stove rear must be
unlocked manually (pressed). The stove is ready for operation again after
acknowledging the error message at the touch display and activating the
burnback and flue gas flap (see ACTIVATING THE BURNBACK AND FLUE GAS
FLAP). The operating mode set is retained.
Note
Maintenance and cleaning work must be performed if overheating occurs! If
this error recurs, operation without danger is no longer guaranteed; notify
customer service immediately.
Low-temperature shutdown
The unit switches off if the stove cools below a minimum temperature. This
switch-off may occur if pellet ignition is delayed.
Electrical excess current protection
The stove has a main fuse (at the rear) to protect against excess current
Automatic cleaning cycle
The speed of the flue gas fan is increased every hour for a short period to blow
ash from the burn pot, increasing the operational safety. The status indicator
CLEANING appears on the display.
Every 5 hours (interval adjustable) an additionally automatic cleaning cycle
is performed. The stove stops, the automatic cleaning tilts the grid and then
re-ignites the stove. The status indicator CLEANING appears on the display
continuously. The cleaning procedure with tilting the grid is to convey ash and
clinker from the burn pot into the ash drawer. This additional function does not
replace a manual cleaning as described in CLEANING and MAINTENANCE, as
this is absolutely necessary to do regularly.
Component monitoring
All the electrical components used are continuously monitored during operation.
If a component is defective or can no longer be actuated correctly, then
operation is stopped and a warning or error message is issued (see WARNING
AND ERROR MESSAGES).
Auger motor monitoring
Too long or wet pellets as well as pellets with too high dust content (see
BRIEF INFORMATION ON FUEL PELLETS) can cause so-called “auger jammers”
in the auger channel. This may also happen if the pellets accumulate in the
burn pot and the backlog reaches into the chute. The auger motor reacts in
both cases with an increased current consumption, which causes the error
message: INSERTION MOTOR JAMMED. The stove will be stopped. Please call
the customer service immediately.

6. INSTALLING THE STOVE
General information
Note
Only use heat-resistant sealing materials as well as corresponding sealing
strips, heat-resistant silicon and rock wool.
Note
Assembly may only be performed by authorised specialist companies.
Note
Also take care that the flue does not project into the free cross-section of
the chimney.
Note
Please observe the regional safety and building regulations. Please contact
your master chimney sweep in this context.
Note
Your stove is intended for room-air independent operation. Thus the stove
pipe connections must be tightly sealed permanently for this use. 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 an approved chimney for solid fuels.
The chimney must have a diameter of min. 100mm for pellet stoves and
130mm -150mm 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 m.
QAvoid to many bends of the flue gas pipes. There should not be more than
3 bends in the exhaust pipe.
QIf you just can not connect directly to the chimney, please 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 15Pa.
QThe derivation of the flue gases must be guaranteed even during a temporary
power outage.
Note
If connecting to multiple connection chimneys additional safety equipment is
required. Your local chimney sweep will advise you in this case.
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.
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.
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.
QCut the perforated rear wall out with a hacksaw.
QConnect at the air intake either a pipe Ø125mm (log wood and combi
stoves) or Ø50mm (pellet stoves) and fix it with a hose clamp (not included!).
At pellet stoves with longer intake pipes than 1m the diameter should be
increased to 100mm. (see RIKA range).
QTo ensure sufficient air intake, the intake pipe should not exceed max. 4m
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.
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.
