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.
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.

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):
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.
