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.
