*e capacity in kg may deviate due to different pellet bulk densities.
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.
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 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.
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.
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
