5. 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.
