Instructions
For installation and for connection of flue, the requirements of the Fire Regulations (FeuVO
in Germany) apply, as well as local building regulations such as the following technical
standards DIN 4705, DIN EN 13384, DIN 18160, DIN EN 1856-2 and DIN EN 15287. In
order for the stove to function correctly the chimney to which you want to connect the stove
must be in good condition.
1.4
Surrounding space
The stove draws the air required for burning from the surrounding room. You must ensure
that sufficient air can be drawn in through non-sealed windows and outside doors. In addi-
tion you must ensure that a room volume/heat capacity ratio of at least 4 m³ per kW nomi-
nal heat capacity is available. If the volume is less than this, then air vents can be used to
provide access to further air supply in other rooms (connecting vents min. 150 cm²).
1.5
Air supply
A constant supply of oxygen or air is required for the combustion process. Normally the air
available in the room where the stove is installed will be sufficient.
If the windows and doors are well insulated, if mechanical air extraction mechanisms are
present (e.g. in a kitchen or bathroom) or if there are other sources of fire (including gas
boilers) in the home, then the supply of available air can be significantly impacted. If this is
the case, the option exists to draw in air for burning directly from outdoors or from another,
well-ventilated room (e.g. a cellar).
The stoves provide a built-in air supply opening in the base, Ø 80 mm.
For the air supply you must use only smooth pipes with a minimum diameter of 80 mm. A
shutoff valve must be placed in the air supply close to the stove, which must be installed
professionally, at the bends there must be inspection openings for the local authority re-
sponsible for approving heating systems and it must be
professionally sealed against
condensation
. The pipe must not be longer than 4 m and must not have more than 3
bends. If the pipe exits out-of-doors, then it must have appropriate wind protection and be
covered by a mesh.
NOTE:
In the room where the stove is installed or in the neighbouring rooms there
must not be any air extractors or similar equipment. These could cause con-
siderable operating problems and even represent a risk. Consult the local au-
thority responsible for approving heating systems.
NOTE:
The room where the stove is to be installed must not have equipment such as
extractor hoods, ventilation systems etc. which could mean that that room or
neighbouring rooms have reduced air pressure.
Important NOTES relevant to operation dependent on air supply from room or inde-
pendent of air supply from room
(valid for Germany):
•
The stoves have been tested under DIN EN 12815 as
cookers relying on air sup-
ply from room
. The stoves take in all the air required for combustion via the central air
intake from the surrounding room. This intake can have an external enclosed air supply
attached to it. Even with this sealed air supply the stoves do not meet the requirements
for operation independent of the air supply from the room.

If used in
combination with air management systems
(e.g. controlled air supply
and evacuation systems, steam extractors or similar) then in Germany Part 4 of Fire
