2.5 Outside air intake
Oxygen or air is constantly required for the combustion process. As a rule, the air
available in the installation room is sufficient (see also Chapter 2.2).
With well-sealed windows and doors, the presence of mechanical ventilation (e.g.
kitchen or bathroom) or other fireplaces (including gas boilers) in the apartment, the
proper air supply can be severely disturbed. If this is the case, it is possible to supply
the combustion air directly from outside or from another, sufficiently ventilated room
(e.g. basement).
For this purpose, the wood-burning stoves offer a central air intake nozzle Ø 100 mm
on the back as standard, which must be installed.
Only smooth pipes with a minimum diameter of 100 mm can be used. The air line
should also have a shut-off valve near the furnace. The position "open" - "closed"
must be clearly marked on the butterfly valve and must be carried out correctly.
Among other things, arches must have inspection openings for the chimney sweep
and be properly insulated against condensation. The line should not be longer than 4
m and not have more than 3 bends. If the line leads outdoors, it should be provided
with a suitable windbreak and fly screen.
General information on the subject of room air dependent or room air inde-
pendent operation:
The stove is supplied as a standard room air-dependent fireplace stove. This means
that the stove draws all of the combustion air from the installation room via the central
air intake on the back. A sufficient supply of combustion air (at full load approx. 25m³ /
h) is absolutely necessary.
In combination with ventilation and air conditioning systems (e.g. controlled ventilation
systems, fume hoods, etc.), Section 4 of the Firing Ordinance (FeuVO) is decisive in
Germany. The flue gas routing must be monitored by special safety devices (e.g. via
an approved differential pressure monitor) or, if a ventilation system is used, this must
ensure that no negative pressures greater than 4 Pa occur in the installation room
compared to the outside and that the necessary combustion air (approx. 25 m3 / h) for
the fireplace.
Please always observe - in consultation with your authorized district chimney sweep -
the applicable local regulations and rules. We cannot accept any liability for changes
made after this manual has been printed. We reserve the right to change without no-
tice.
The above-mentioned safety devices are not a substitute for professional planning
and design of an adequate combustion air supply.
As part of the acceptance, the district chimney sweep must check the adequate com-
bustion air supply / overall installation.
