Air supply for combustion via the room where the appliance is
located
the air required for combustion is drawn from the room where the appliance
is located. the room must be periodically ventilated, especially in well sealed
buildings.
therefore provide sufficient changes of air in the room where the appliance is
located. For rooms exceeding a volume of 50 m3, we recommend exchanging
1.5 times the volume of air per hour. For smaller rooms the rate of air exchange
should be increased.
If there are additional heating appliances in the same room, make sure that
the air inlets can supply sufficient air for combustion for the operation of all
appliances.
Only if certain conditions are fulfilled it is permissible to operate open-flued
fireplaces in combination with ventilation systems etc. For further information
seek the advice of the manufacturer of your ventilation system.

(Figure 5)
•
the air for combustion is pre-heated.
•
It is necessary to ventilate the room at regular intervals or to provide a per-
manent opening for ventilation to the outside.

the air for combustion is only slightly pre-heated!

Max. length 4 m with 3 bends.
Negative pressures in the room where the ap-
pliance is located (e.g. through ventilation sys-
tems, extractor hoods, etc.) may impair the func-
tioning of the fireplace and its safety system and
are therefore not permissible.
Please consult the local qualified chimney
sweep and observe the local fire protection laws
as well as the standards DIN 18896 (technical
standards for the installation and the operation
of fireplaces for solid fuels).

Operate extractor hoods only with re-circulated
air operation!
With ducted extractor hoods, an adequate sup-
ply of air must be ensured by means of separate
safety equipment (e.g. contact switches on the
windows, negative-pressure monitoring).
