Stove functioning

The stove has 2 combustion chambers:
• the upper combustion chamber (UCC) is for kindling/refuelling
• the lower combustion chamber (LCC) is for post-combustion and may not be used
for kindling and refuelling
A post-combustion provides a good usage of the
fuel energi and an almost complete combustion
of the toxic and harmful substances from
the smoke.
Upon lighting the air flows through the UCC and to the flue
pipe (chimney). When the stove reaches a certain temperature,
the air flow is diverted, and the still unburned gasses is lead
from the UCC through an opening in the bottom stone plate
to the LCC. Over the opening is placed a steel dome.
Flames are thus lead through the opening to the LCC for
post-combustion of the gases.

Automatic regulation of combustion air

This stove is equipped with an independent and self-regulating air damper.
Hence there is no damper handle.
The primary air is added to the primary combustion zone, i.e. the bed of glowing em-
bers.
This cold air is only used in the lighting stage.
Secondary air is air added in the gas combustion zone, i.e. air which contributes to
the combustion of the pyrolysis gasses (preheated air, which is used for the cleaner
glass system and combustion). This air is sucked through the damper and is pre-heated
through the side channels and then emitted as hot scavenging air onto the glass. The
hot air rinses the glass and keeps it soot-free.
A clean combustion is indicated by clear yellow flames.
The pilot nozzles are placed in the back plate of the upper combustion chamber. They
ensure that the bed of glowing embers is fed with air and therefore holds a high tem-
perature. It provides a quick start when refuelling and reduces the risk of fire going out.
IMPORTANT! - during kindling/refuelling
If an ash pan is used, it must be placed at the bottom
of the lower combustion chamber.
