2.2.2 COMBUSTION AIR SUPPLY

The combustion air supply can be realised in different ways ac-
cording to 2.2.2.1 and 2.2.2.2.

2.2.2.1 DEPENDENT ON ROOM AIR

Your stove takes its combustion air from the installation room
(operation dependent on room air). It must be ensured that the
installation room is supplied with sufficient fresh air (more informa-
tion in the FeuVO for the relevant German state, DIN 18896, spe-
cialist regulations, etc.). The provision of fresh air is to be checked
by the fitter and the operator. It must be ensured that there is
sufficient combustion air when multiple fireplaces are operated in
one room or connected rooms. In the event of sealed windows and
doors (e.g. in combination with energy saving measures), it may be
the case that the supply of fresh air is not sufficiently guaranteed.
This may adversely affect the drawing behaviour of the stove. This
can affect your well-being and under certain circumstances your
safety. If necessary, an air flap for an additional fresh air supply
must be fitted near to the stove or an external combustion air flue
fitted to the outside (see 2.2.2.2) or the stove moved to a well-
ventilated room (excluding a heating room). In particular, it must
be ensured that the required combustion air pipes are open during
the operation of the fireplace. This means that operating the stove
at the same time as a ventilation system (e.g. cooker extractor
hood, bathroom fan, etc.) in the same room or group of rooms can
negatively affect the stove's performance (ranging to the leakage
of smoke or exhaust gas into the living room, despite the firebox
door being closed). Therefore, operation of such devices at the
same time as the stove without suitable measures is prohibited!

2.2.2.2 SEPARATE COMBUSTION AIR SUPPLY

It is possible to supply the stove separately with combustion air. The
separate combustion air connection can either be connected to the
rear of the stove or from below. The socket is premounted and the
outer casing is to be opened accordingly. By connecting an air pipe
to the combustion air connection socket, it is possible to connect
combustion air from outside or from another room, e.g. the cellar,
to the stove. When connecting the stove to a combustion air supply,
ensure that the information in the TROL (specialist regulations), DIN
18896, etc. are observed and used. In particular, it is important
to ensure that the pipes have sufficient dimensions!
If using a rotary base, the connection must be designed to be
permanently flexible! The rotary operation may not be adversely
affected.
Combustion air openings and pipes must not be closed or blocked,
insofar as it is not guaranteed by special safety devices that the
fireplace can only be operated when the shutter is open. The
cross-section of the pipe may not be made narrower with a shutter
or a grate. If the pipe for the combustion air is fed out of the build-
ing then it is to be fitted with a flow restrictor. In the process, the
position of the flow restrictor must be recognisable from outside
of the pipe. When fitted in this way, the pipe should be insulated
because it is possible for condensation to form. In addition, the
pipe should be fitted so that no water or other materials can
penetrate into the stove and any condensation that may possibly
form can flow outside. According to the regulations, combustion air
pipes in buildings with more than two floors that bridge fire walls
are to be installed in such a way that fire and smoke cannot be
transferred into other floors or fire compartments. German state
and local fire protection regulations are to be observed!
