call this combustion air). The stove
provides excellent heating efficiency
and the window is easy to maintain as
the secondary air ‘flushes’ the surface
of the glass. Note that the stove will,
of course, blacken if the airflow is too
low. If there is too little oxygen, there
is a risk that the window, etc. will
Blacken due to the formation of soot
deposits. A combination of incorrect
combustion and damp wood fuel can
cause a heavy, sticky coat of soot
to form, which may cause the door
seal to tear off next time the door is
opened.
Risk of explosion
After you add new fuel, it
is very important that you do
not leave the stove unat
tended until the wood is burning
constantly. This will normally occur
within 30 to 60 seconds.
A risk of explosion can possibly arise if
too much wood is placed in the stove.
This may result in the production of
large volumes of gas, and this gas can
explode if the intake of primary and
secondary air is insufficient.
It is an advantage always to leave some
ash lying in the bottom of the comb-
stion chamber.
Take care when emptying the ash
pan, as cinders can continue to burn
in the ash for long periods of time.
Reduced rate of combustion
The stove is suitable for intermittent
use. If you require a lower rate of heat
effect, fill the combustion chamber
with less wood. Allow lower combu-
stion airflow. Do not forget that the
combustion airflow must never be
completely closed when lighting up.
It is important to maintain the layer of
embers. Low-effect heating is achie-
ved when the wood is glowing, i.e.
there are no more flames because the
wood fuel has been transformed into
glowing charcoal.
Optimal combustion
For optimal combustion and heating,
this stove is designed to provide an
optimum mix of primary and se-
condary air (in these instructions, we
