*Practical values may vary depending on pellet quality.
Note
Pellet consumption depends on the size of the pellets. The larger
the pellet, the slower the feed and vice versa.
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.

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.

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.
QIf 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.

10
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):
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 independent stove
according to EN13240 and to EN14785 and can be installed as well
room-air dependent and independent. In Germany it does not
conform to the requirements for room-air independent operation.
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.
Convection air conduction
only for stoves with MULTIAIR
The MULTIAIR equipped stove is delivered with a cover on the
convection air outlet to prevent direct heat to the wall.
Operation without this cover or without attached convection pipes is
not allowed. If you do though no warranty and no liability is accepted
for damage.
QThe amount of air and temperature of one fan is designed to heat
one additional room.
QNote the regional specific fire safety regulations and clarify the
connection situation with the competent authority
QThe max. temperature of the convection air is 180 °C at the air
outlet.
QThe convection air canal should be as short as possible.
QKeep the number of deflections as small as possible.
Note
Please pay attention to the national and country-specific building
and fire regulations when connecting the convection air pipes.
Installation and assembly must be performed by a trained
specialist only.
