3. INSTALLING THE STOVE
General information
Note
Assembly may only be performed by authorised specialist companies.
Note
Please observe the regional safety and building regulations. Please contact
your master chimney sweep in this context.
Note
Only use heat-resistant sealing materials as well as corresponding sealing
strips, heat-resistant silicon and rock wool.
Note
Also take care that the flue does not project into the free cross-section of the
chimney.
Note
In case of room-air independent operation the stove pipe connections must
be tightly sealed permanently. 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.
Connection to the chimney
Q
The device must be connected to an approved chimney for solid fuels.
The chimney must have a diameter of min. 100 mm for pellet stoves and
130 mm -150 mm for log wood stoves depending on the diameter of the flue
pipes.
Q
Avoid long flue pipes to the chimney. The horizontal length of the flue pipe
should not exceed 1.5 metres.
Q
Avoid to many bends of the flue gas pipes. There should not be more than
3 bends in the exhaust pipe.
Q
Please use a connection with a cleaning opening.
Q
Connections must be made of metal and must meet the requirements of the
standard (install the connections airtight).
Q
Before installing a chimney calculation must be made. The evidence must
be performed for single occupancy to EN13384-1 and EN13384-2 for multiple
occupancy.
Q
The maximum draft of the chimney should not exceed 15 Pa.
Q
The derivation of the flue gases must be guaranteed even during a temporary
power outage.
Note
If connecting to multiple connection chimneys and depending on country
regulations, additional safety equipment is required. Your local chimney
sweep will advise you in this case.
Note
Be sure to prevent condensed water from entering via the flue connection.
You may need to have a condensate ring installed - ask your chimney
sweeping expert for more information. Damages caused by condensate are
excluded from manufacturer’s warranty.
Connecting to a steel chimney
The connection must be calculated and shown with EN13384-1
and EN13384-2.
Use only insulated (double) stainless steel tubes (flexible aluminum or steel
tubes are not permitted).
An inspection door for regular inspection and cleaning must be present.
The flue pipe connection to the chimney has to be air-tight.
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.
Feeding in external combustion air
only for devices which are able to run in room-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
Connect at the air intake either a pipe Ø 125 mm for log wood and combi
stoves, or Ø 50 mm or Ø 60 mm for pellet stoves. Fix it with a hose clamp
(not included!). At pellet stoves with longer intake pipes than 1 m the
diameter should be increased to 100 mm. (see RIKA range).
Q
To ensure sufficient air intake, the intake pipe should not exceed max.
4 metres and have max. 3 bends.
Q
If the line leads outside it must have a windbreak.
Q
In extreme cold pay attention to icing on 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.
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.
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.
