Regulating the combustion air

The stoves are equipped with a one-handed operating lever for regulating the damper.
The stove-specific regulating mechanisms can be seen on the diagrams (front of manual).
Primary air is the combustion air added to the primary combustion zone, i.e. the bed of
glowing embers. This air, which is cold, is only used in the lighting stage.
Secondary air is the air, added to the gas combustion zone, meaning air, which contrib-
utes to the combustion of the pyrolysis gasses (preheated air, used for cleaning the glass
and combustion). This air is sucked through the damper below the burning chamber 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.
Tertiary air at the back of the burning chamber at the top (row of holes) ensures the com-
bustion of the final gas residues and particles before leaving through the chimney.
By setting the interval between position 1 and 2 (firewood) and between position 2 and
3 (coal), the energy content in the firewood/coal is used optimally, as there is oxygen for
combustion and for the burning of the pyrolysis gasses. When the flames are a clear yel-
low the damper has been set correctly. Finding the correct position comes with time after
you have used for stove for a while.
It is not recommended that you turn it down completely. A mistake commonly made is
shutting the damper too early because it feels too hot. This results in dark smoke ema-
nating from the chimney and in the calorific value of the firewood not being used to its
fullest.
See Warning on page 76.

Room ventilation

There must not be an extractor fan fitted in the same room as the stove as this can cause
the stove to emit smoke and fumes into the room.
The stove requires a permanent and adequate air supply in order for it to operate safely
and efficiently.
In accordance with current Building Regulations the installer may have fitted a permanent
air supply vent into the room in which the stove is installed to provide combustion air. This
air vent should not under any circumstances be shut off or sealed.

Adjustment of the air damper

- the damper has 3 settings (see photos in front of manual).
Position 1
Push the lever all the way in.
The damper is almost closed; there is a minimal air intake. This position must be avoided
during normal operation.
