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 pellet 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 some 20 Watt in heating operation. And approx. 150
Watt during automatic ignition. The connection cable must be laid in a way 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.
QMake sure that no embers fall out of the combustion chamber onto
inflammable material.
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
3. to open the sliding door
b > 43cm
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.
The correct chimney connection
There are several ways to connect your stove to the chimney, eg:
*1
*2
*3
*1
*2
*3
1) wind break, 2) chimney, 3) inspection opening
For the selection of the connection and to ensure a proper connection between
the stove and chimney, please read the guide „INSTALLING THE STOVE“ or ask
your local chimney sweep.
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 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.
QIf this occurs, disconnect the mains plug. Phone the fire brigade and get
yourself and other residents out of harm’s way.
Note
Your pellet stove can be operated room air dependent or room air independent.
ROOM-AIR INDEPENDENT OPERATION:
The stove is certificated for type FC62x of the approval principles for the
inspection and evaluation of ambient air independent fireplaces specified by
the Deutsches Institut für Bautechnik (DIBT) (German Institute for Building
Technology). Thanks to the air-tight configuration of the air supply line and flue
pipes the stove may be operated in air-tight rooms and in rooms with room-air
installations (e.g. controlled ventilation and venting systems, extractors etc.).
ROOM-AIR DEPENDENT 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). 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
Wood pellet specification according to ENplus –

3) a maximum of 1% of the pellets may be longer than 40 mm,
max. length is 45 mm
4) the limit value of ≥97,7 Ma.-% applies when conducting measurements with a
lignotester (internal control)
Note
Please ask your pellet stove dealer for tested fuel and a list of monitored fuel
manufacturers.
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. Observe waste
incineration legislation!
Only burn pellets that have been inspected according to ÖNORM, DIN Plus
or ENplus-A1.
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.
Note
Your pellet stove is only approved for the burning of wood or pellets of
tested quality. Burning straw, maize, woodchips etc. is not permitted! Non-
observance of these regulations makes void all warranty and guarantee
claims and may impair the safety of the unit!
