5. INSTALLING THE STOVE
General information
The smoke extraction system is based on negative pressure in the combustion
chamber and a slight excess pressure in the flue gas outlet. Therefore it is
important that the flue connection is installed correctly and airtight
Note
Only use heat-resistant sealing materials as well as corresponding sealing
strips, heat-resistant silicon and rock wool.
Note
Assembly may only be performed by authorised specialist companies.
Note
Also take care that the flue does not project into the free cross-section of
the chimney.
Note
Please observe the regional safety and building regulations. Please contact
your master chimney sweep in this context.
Avoid flue pipes to the stove being too long. The horizontal length of an exhaust
line should not exceed 1.5m.
Avoid frequent changes in direction of the exhaust gas flow to the chimney.
There should be a maximum of 3 bends in the exhaust line.
If you cannot connect directly straight to the chimney, use a connection with a
cleaning opening if possible.
Note
Your stove is intended for room-air independent operation. Thus the stove
pipe connections must be tightly sealed permanently for this use. Use a heat-
proof silicon to position the stove pipe on the conical supports of the flue tube
nozzles and for insertion in the chimney flue lining.
Note
The stove should not be pushed on unprotected floors.
Tip
Strong corrugated cardboard, 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.
Combustion air
Every combustion process requires oxygen from the surrounding air. This so-
called combustion air is removed from the living are in the case of individual
stoves without external air connections.
This air removed must be replaced in the living space. Very tightly sealed
windows and doors in modern flats may mean that too little air replaces that
used. The situation also becomes problematical due to additional venting in
flats (e.g. in the kitchen or WC). If you cannot feed in external combustion air,
then air the room several times a day to prevent negativce pressure in the room
or poor combustion
Note
Please note that problems may arise due to updrafts in the case of
combustion air supply from an integrated chimney ventilation shaft. If the
combustion air flowing downwards is heated it may rise and thus counter
the chimney with a resistance which in turn reduces the negative pressure
in the combustion chamber. The chimney manufacturer is to guarantee that
the resistance for the combustion air is a maximum 2 Pa even in the least
favourable operating state of the chimney
Feeding in external combustion air
only for devices which are able to run in romm-air independent operation.
Q
Combustion air must be fed to the stove from outside via a sealed pipe
for operation independent of the room air. According to EnEV, it must be
possible to shut off the combustion air pipe. The open/closed setting must
be clearly recognisable.
Q
Cut the perforated right rear wall out with a hacksaw.
Q
Connect to the intake nozzle either a pipe Ø125mm (logs stove and combi
stove) or Ø50mm (pellet stove) and fix this with a pipe clamp (not included
in scope of supply!) On pellet stoves with longer connection pipes, the
diameter should be enlarged to some Ø100mm after approx. 1m.
Q
To ensure sufficient air intake, the line should not be longer than 4m and
should not have too many bends.
Q
If the line leads outside it must have a windbreak.
Q
In extreme cold pay attention to icing of the air intake opening (check).
Q
It is also possible to suction in combustion air directly from another
sufficiently vented room (e.g. cellar).
Q
The combustion air pipe must be tightly connected (adhesive or cement)
permanently to the air nozzles of the stove.
Q
If you do not use the stove for a long time, please close the combustion air
intake to prevent the stove from moisture.
If one or more of these conditions does NOT apply, the result is poor combustion in the
stove and negative pressure in the installation room.
Convection air conduction
The 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.
Q
The amount of air and temperature is designed to heat one additional room.
Q
Note the regional specific fire safety regulations and clarify the connection
situation with the competent authority
Q
The max. temperature of the convection air is 180° C at the air outlet.
Q
The convection air should be as short as possible.
Q
Keep 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.
