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 warrant.
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 woodburning stove (not in a pelletstove!). The cardboard and film (PE) can be depolluted via the municipal waste collection for recycling.

2. IMPORTANT INFORMATION
General warning and safety information
Observance of the introductory general warning information is imperative.
Q Read 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.
Q RIKA 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.
Q Only approved transport equipment with sufficient load carrying capacity
may be used with your heating appliance.
Q Your heating appliance is not suitable for use as a ladder or stationary
scaffolding.
Q The 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).
Q Make your children aware of this particular danger and keep them away from
the stove during heating.
Q Only burn approved heating materials.
Q The 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.
Q No light or inflammable clothing is to be worn when post-heating.
Q Use the heat-resistant gloves supplied to open the doors of your stove.
Q Only 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.
Q Push the embers together to form a firebed when you add new fuel (logs).
Q Placing non-heat resistant objects on the stove or near it is prohibited.
Q Do not place clothing on the stove to dry.
Q Laundry racks etc. must be placed at a sufficient distance to the stove –
ACUTE DANGER OF FIRE!
Q When 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.

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
Q Flue 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.
Q Please observe the corresponding installation guidelines for walls panelled
with wood when connecting your flue pipes to the stove.
Q Observe the formation of flue gas (atmospheric inversion) and draughts
when the weather is unfavourable.
Q Infeed 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.
Q If 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):
Q Suitable for multiple occupancy. (Note the different country regulations.)
Q These may only be operated with the combustion chamber door closed.
Q The 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.
Q The combustion chamber door is to be kept closed when the stove is not
in operation.
Q Fouling 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.
Q If 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 non­approved 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 long­lasting 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:
Q Too much firewood leads to overheating. This can damage your stove and
increases the exhaust emission values.
Q If 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.
Q For right quantity of firewood see AMOUNT OF FUEL.

4. INSTALLING THE STOVE
General information
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
Q The 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.
Q Avoid long flue pipes to the chimney. The horizontal length of the flue pipe
should not exceed 1.5 m.
Q Avoid to many bends of the flue gas pipes. There should not be more than
3 bends in the exhaust pipe.
Q If you just can not connect directly to the chimney, please use a connection
with a cleaning opening.
Q Connections must be made of metal and must meet the requirements of the
standard (install the connections airtight).
Q Before installing a chimney calculation must be made. The evidence must be
performed for single occupancy to EN13384-1 and EN13384-2 for multiple occupancy.
Q The maximum draft of the chimney should not exceed 15Pa.
Q The 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 so­called 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.
Q Combustion 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.
Q Cut the perforated rear wall out with a hacksaw.
Q Connect 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).
Q To ensure sufficient air intake, the intake pipe should not exceed max. 4m
and have max. 3 bends.
Q If the line leads outside it must have a windbreak.
Q In extreme cold pay attention to icing on the air intake opening (check).
Q It is also possible to suction in combustion air directly from another
sufficiently vented room (e.g. cellar).
Q The combustion air pipe must be tightly connected (adhesive or cement)
permanently to the air nozzles of the stove.
Q If 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. CLEANING AND MAINTENANCE
Basic information
Note
When you vacuum clean around the stove ensure that you do not vacuum into the combustion air intake during heating operation. You could vacuum out embers – FIRE RISK!
Note
Your stove must be cooled before any maintenance work is performed.
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 is dry and untreated.
Tip
Wood as fertiliser - The mineral content of the wood remains in the combustion chamber as ash as a residue of the combustion. This is an excellent fertiliser for all plants in the garden; it is a completely natural product. The ash should be stored first and extinguished with water.
Note
Ash may contain embers – only place ash in sheet steel containers.
Cleaning flue pipes
The exhaust pipes should be cleaned twice a year.
Remove the flue pipes. Inspect and clean chimney connection. Brush off any soot and dust deposits 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.
Open the firebox door. Open the grate and remove the left bottom fire brick.
Close the grate again. Now lift the upper baffle plate slightly and remave the left fire brick.
Now you can remove the top baffle plate.
Remove the cover by simply lifting.
Open the 7 screws and remove the cover plate.
Clean the flue gas passes with the supplied wire brush
Then clean the combustion chamber well.
Install the removed parts in reverse order again.

Empty the ash drawer
Empty the ash drawer regularly. You can simply pull forward the ash drawer with open fire door
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. Usual cleaners containing acid or solvents can be too harsh and damage the glass.
Cleaning of painted surfaces
Wipe of the painted surfaces with a damp cloth, do not scrub. Do not use solvent-containing cleaners.
Cleaning the convection air openings
Vacuum clean any dust deposits from the convection air openings at regular intervals.
The stove should be cleaned thoroughly prior to the start of the heating season to prevent excess odour.
Combustion air - air intake
If necessary, please also clean the air intake with a hoover.
Note
Only when the stove is cold! You could vacuum out embers – FIRE RISK!
Checking door seal
The condition of the seals at doors and glass should be checked at least once a year. Repair or replace seals depending on condition.
Note
Only intact seals ensure your stove works perfectly.
