______________________________________________________________________
Important NOTES relevant to operation dependent on air supply from room or
independent of air supply from room (valid for Germany – as of January 2013):

The stoves have been tested under DIN EN 12815 as stoves relying on air supply
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
Regulations (FeuVO) apply. These determine among other things, that the stove and
the air management systems must be jointly managed (e.g. using a differential
pressure monitor) or an air supply system must be installed, which is approved for
use with solid fuel stoves and which supplies the room where it is installed with
sufficient additional air (approx. 20 m³/h) for the combustion in the fire box.

You must always comply – in consultation with the local authority responsible for
approving heating systems – with the local rules and regulations. We cannot
accept any responsibility for changes subsequent to the publication of this instruction
manual. We reserve the right to make changes.
