Note

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 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 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.
QPlacing non-heat resistant objects on the stove or near it is prohibited.
QDo not place clothing on the stove to dry.
QStands for drying clothes 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!
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.
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.
QUse the heat-resistant gloves supplied to open the doors of your stove.
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)
Note
on ROOM-AIR DEPENDENT and
ROOM-AIR INDEPENDENT OPERATION:
Your stove has been tested as a room-air dependent stove according to EN
14785 and does not conform in Germany to the requirements for room-
air independent 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 etc.). The combustion air
infeed of approx. 40 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 –

1) in an anhydrous state
2) diameter must be specified
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!
