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 responsible 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
considerable operating problems and even represent a risk. Consult the
local authority 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.
