PACKAGING
Your first impression is important to us!
The packaging of your new stove provides excellent pro-
tection against damage. However damage to the stove and
accessories may still occur during transport.
Please examine your stove carefully for damage and
ensure all parts are there on receipt! Report any de-
fects to your stove dealer immediately!
When unpacking ensure that the stone panels are
intact. The material scratches easily. Natural stone is
not covered by the warranty.
The packaging of your new stove is environmentally neu-
tral to a great extent.
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.

GENERAL WARNING AND
SAFETY INFORMATION
Observe the introductory general warning information
- Read the entire manual thoroughly before putting the
stove into service. Please read these instructions
before installation and operation. Observe the
national provisions and laws as well as the regu-
lations and rules applicable locally.
- Only approved transport equipment with sufficient
load carrying capacity may be used with your heating
appliance.
- Your heating appliance is not suitable for use as a
ladder or stationary scaffolding.
- The burning of fuel releases heat energy that leads 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 with-
out appropriate protective clothing or equipment e.g.
heat-resistant gloves or means of operation (cold
hand).
- Make your children aware of this particular danger
and keep them away from the stove during heating.
- Only burn the approved materials listed in the Chap-
ter “Clean burning”.
- The 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 explo-
sion.
- No light or inflammable clothing is to be worn when
post-heating.
- Placing non-heat resistant objects on the stove or
near it is prohibited.
- Do not place clothing on the stove to dry.
- Stands for drying clothes etc. must be placed at a
sufficient distance to the stove due to the danger of
fire!
- When your stove is burning, the use of highly inflam-
mable and explosive materials in the same or adja-
cent rooms is prohibited.
PRIOR TO SET-UP
1.1 Floor bearing capacity:
Ensure that the substructure is capable of bearing
the weight of the stove prior to set-up.
Modifications to the firing installation may not be
performed. This leads to loss of warranty and guar-
antee.
SAFETY DISTANCES (minimum distances)
1. To non-inflammable objects
a > 400 mm b > 100 mm
2. To inflammable objects and to reinforced concrete
bearing walls
a > 800 mm b > 200 mm

1.2 Flue pipe connection
Flue pipes pose a particular source of hazard regarding
gas leaks and fire. Get the advice of an authorised special-
ist company for the layout and assembly.
Please observe the corresponding installation guidelines
for walls panelled with wood when connecting your flue
pipes to the stove,
1.3
Observe the formation of flue gas (atmospheric inversion)
and draughts when the weather is unfavourable.
Infeed 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.
If 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 con-
nected to your chimney.
1.4
Push the embers together to form a firebed when you add
new fuel.
1.5
Only use suitable tools when handling embers and make
sure that no embers fall out of the combustion chamber
onto inflammable material.
1.6
Use the equipment supplied to open the doors of your
stove, e.g. heat-resistant gloves.
1.7 Stoves type 1 (BA 1):
These may only be operated with the combustion chamber
door closed.
1.8
The 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 endan-
gered. The combustion chamber door is to be kept closed
when the stove is not in operation.
1.9
Fouling 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.
If this occurs phone the fire brigade and get yourself and
other residents out of harm’s way.
Note: The size of the combustion chamber door makes
it necessary, particularly with post-heating when
ablaze, not to open the door too abruptly to prevent
the tips of the flames reaching out.

SUITABLE FUELS AND FUELS
QUANTITIES
Your stove is generally suitable for burning dry firewood
and wood briquettes.
Only use dry fuel (moisture content between 14 and 18 %).
Burning waste of any kind, particularly plastic, damages
your stove and chimney and is prohibited by the emission
reduction laws.
FUEL QUANTITIES
The stove is fitted with a construction-specific flat
firebox. This means only one layer of fuel may be laid
on the base embers.
Please observe that adding greater quantities of fuel
leads to emission of more heat and greater heating of
the stove than it is designed for. This may cause dam-
age to your stove.
WOOD TYPES
Different types of wood have different fuel values.
Deciduous wood 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.

Your stove output is regulated via the knob. This regulator
knob must be used according to your own experience
since your stove output also depends on the chimney
draught.
the seconary air regulator, the primary air
regulator and the shaker grate handle may only
be used with the schake hook enclosed.

E N G L I S H
Facing the challenges of our times means assuming re-
sponsibility. Maintaining our natural world is now one of
our most important tasks. Our products represent devel-
opments according to the state of the art. This is the main
precondition for clean, efficient and problem-free working
of our stoves.
CLEAN BURNING
Clean combustion requires:
1. DRY AND UNTREATED FIREWOOD.
Guideline between 14 % and 18 % relative wood moisture.
Wood stored dry and ventilated for 2 – 3 years.
A stove is not a waste incinerator. The warranty lapses
if waste or non-approved materials such as plastic,
treated wood etc. are burnt!
This leads to damage to the stove and chimney and
environmental pollution!
2. THE RIGHT QUANTITY OF FIREWOOD
AND FIREWOOD DIMENSIONS
- Too much firewood leads to overheating.
This stresses the material too much and leads to poor flue
gas values.
- Too little firewood or logs being too large means the
stove does not reach optimum operating temperature.
The flue gas values are also poor in this case.
- Correct quantity of firewood means:
For wood ≈1,6 kg (2 split logs - 25 cm long) per layer
(standard) for nominal heat output 6 kW. For lowest heat
output (3 kW) ≈0,8 kg (1 split log - 25 cm long)
Note: Only wood and wood briquettes may be burnt in
your stove. Plastics, treated wood (e.g. chipboard),
coal and textiles may not be burnt.
BURNING WOOD
The clean burning of wood represents the same chemical
process as natural rotting, i.e. the CO
2
(carbon dioxide)
released does not additionally increase or burden the
original CO
2
content in the atmosphere.

Before first commissioning or after changing the loca-
tion of the fire, cleaning and service work, ensure that
the flue plate, as well as the wood stop (Fig. Combus-
tion chamber, Part 33 and 31) is in the correct position.
When using a flue pipe with throttle valve, the throttle
valve must be open.
Care must be taken with this fire that the flue draught
reaches at least the prescribed value (> 10 Pa). Should
problems arise here, please contact your master chim-
ney sweep.
CONNECTING THE FIRE
Proceed as follows for new connections in a brick-built
chimney:
1. Measure and mark out the stove connection (take into
consideration any floor plate thickness) according to natu-
ral dimensions.
2. Chisel out (drill) the hole in the brickwork.
3. Brick in the wall liner.
Seal the wall liner first with mineral rock wool. Render
with heat-resistant cement mortar or equivalent.
4. Position the floor plate with floor protection (cardboard)
once the mortar has set and after painting.
5. The stove can now be carefully lifted onto the floor plate.
The stove should not be pushed on unprotected
floors.
Strong corrugated cardboard or e.g. old carpet is
useful to assist assembly and as a base. The stove
can also be pushed on this cardboard or carpet.
We recommend original flue pipes from RIKA for proper
connection.
The connection may not project into the chimney shaft!
Seal the gap between flue pipe and wall liner with ceramic
sealer.
The installation must conform to the respective safety
and building regulations.
Please contact your master chimney sweep in this
context. He will be pleased to inform you.
If you use a system chimney (e.g. glazed fireclay) we
would ask you follow the manufacturer’s connection
instructions closely.

STARTING THE FIRE
In order to keep exhaust emissions as low as possible, we
would ask you to keep to the following starting instruc-
tions.
1.
If the fire and chimney are still cold or if there is atmos-
pheric low pressure, then burning some paper at the start
is recommended, in order to “drive” the cold out of the
fire and chimney.
2.
To start heating first lay untreated paper on the floor of
the combustion chamber, on top of that 0.5 kg soft wood
chip and 1 kg wood (3 small billets).
Pull the shaker grate handle out completely and open the
primary and secondary air slide
Please do not use glossy paper or paper from maga-
zines. It does not burn well and the print colours pro-
duce very poisonous substances in the flue gas.
3.
Now light the paper. Wait until the soft wood chips are
burning well. Close the shaker grate handle and the pri-
mary air slide a few minutes later. Set the secondary air
slide to the ideal setting a few minutes later.
4.
After this has burned, lay approx 1.6 kg wood (3 billets)
on the fire. Open the shaker grate handle and the primary
air slide until the wood is burning well. The secondary sir
slide remains in the ideal setting. Proceed in the same
manner for each further layer.
5.
The mineral parts of the wood (approx. 1%) remain on
the bottom of the combustion chamber as combustion
residue.
This ash is – because it is a natural product - an excellent
fertiliser for all plants in the garden. However the ash
should be left to settle beforehand and doused with water.
NOTE:
If a lot of smoke develops when wood is placed on a
low firebed and if the riddle grate and primary air are
only opened then, a explosive gas/air mixture may
arise and cause a deflagration. It is recommended for
safety reasons to start fire lighting again.

14
E N G L I S H
THE FIRE PAINT ONLY HARDENS PROPERLY AF-
TER HEATING UP DURING USE.
Do not touch the surface during heating. It is still soft.
Our paints are completely harmless in accordance with
the TÜV-certificate; there is no danger to health. In
spite of that we recommend that the house is well
ventilated several times after first heating.
Heat the fire up well – this will reduce the hardening
time.
Hardening of the surface is complete after several
proper periods of heating.
All details on the nature of the fire wood and correct
heating can be found in Chapter 2.
ASH DRAWER
(Illustrated in Fire, Part 46)
The ash drawer must be emptied regularly to prevent
excessive heating of the fire grid.
Never heat the fire with the ash drawer open
→danger of overheating →loss of warranty.
Caution: Embers could remain in the ash. Only fill the
ash into non-flammable containers and do not put the
ash onto flammable surfaces.
OPERATING THE SHAKER GRATE
The ash is moved from the fire into the ash rawer (part
46) by moving the shaker grate handle (Part 41) to and
fro. This frees up room for the primary feed air that is
required for the heating phase in the fire.
It is not necessary to operate the shaker grate
during heating.
SLIDE SETTING AT RATED THER-
MAL OUTPUT
Fuel Wood/wood briquettes
Primary air closed (0%)
Secondary air 2/3 closed (66%)
Riddle grate closed
The position „Primary air completely open“ may only be
used as a starting position.
As your fire output is also dependent on the chimney
draught and the weather conditions, you must get used to
the use of this secondary control slide according to your
own experience
.

GENERAL MAINTENANCE
Your Tango has been designed by our development team
with minimal maintenance in mind and for a very long
service life. Certain cleaning activities and checkin the
seals are however necessary from time to time. The time
periods between the inspection intervals are above all
dependent on the fire wood quantity used and the fre-
quency of use.
All maintenance and cleaning work must only be car-
ried out when the fire is completely cooled down.
ONCE MORE
Only use wood that has been stored properly
and is dry and untreated. Feed the correct quan-
tity of wood into the fire.
Should the fuel be poor, the number of necessary
maintenance activities can more than double.
FINISH – CONDITION AND CLEAN-
ING
The door glass can be cleaned using RIKA glass cleaner.
The RIKA glass cleaner can be obtained from your spe-
cialist fire dealer.
Should the glass become heavily sooted the possible
cause could be damp wood.
The fire finish is highly refractory and must only be
cleaned using a cloth (damp if necessary). Only use
original paint for touch up work, this is available from
your specialist dealer as an accessory.
Under no circumstances must the paint be
cleaned before heating for the first time!
CONVECTION AIR OPENINGS
Regularly clean dust deposit from the convection air
openings. The fire should be cleaned thoroughly before
the start of the new heating season, in order to prevent
strong odours.
CLEANING THE FLUE GAS CHAN-
NELS (1 x annually)
➧ Removing the flue pipes
➧ Brush off any soot and dust deposits in the fire and in
the flue pipes and vacuum.
➧ Check the seals on the fire door or the ash drawer
before the beginning and end of the heating period.
Should they be damaged or excessively worn, then please
order the relevant replacement.
Only intact seals guarantee the perfect function of your
fire.
