This will reduce temperature of the combustion chamber. At the same
time, the volatile particles driven out of wood will need a lot of air to pass
through this critical phase and flame up fast to reach high temperature
required for clean combustion.
When the fire is burning bright, the combustion air control element can
be set to rated power position.
If you do not wish to stoke up more wood, move the control element in-
to Glow position as soon as no flames are visible, to avoid temperature
loss through unnecessary streaming of air into the fireplace. You cannot
choose this control element position during combustion and degassing
of wood, because this will cut off air completely and the fire goes out.
In case of rapid air streaming from the room (when fireplace door is
opened) it is possible that the gases "trapped" inside the combustion
chamber and downstream radiators/accumulators will suddenly react
with oxygen and explode (deflagration).
Another hint:
Use always smaller pieces of wood for lighting up. These
will flame up faster and cause temperature in the combustion chamber to
increase. The bigger and thicker logs are better for stoking fire. Some sorts
of wood briquettes can swell during combustion, i.e. they expand under
heat and their volume increases. That kind of fuel must be placed always
close to the back wall of combustion chamber, to prevent contact with glass
door.

CLEANING
Once in a year, when the heating season begins, make sure to inspect the
smoke pipe for ashes and residues. This should be possible through a revi-
sion provided on the installed fireplace insert. Remove the cleaning inlays
from the hotplate and clean the ashes with a suitable vacuum cleaner.
When the fireplace was not used for a long time, call the chimney sweep to
inspect and clean your chimney.
