Regulating the combustion air
All RAIS stoves are equipped with a one-handed operating lever for regulating the damp-
er. The stove-specific regulating mechanisms can be seen on the diagrams.
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 which is added in the gas combustion zone, i.e. air which contrib-
utes 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 under the combus-
tion chamber and is pre-heated through the side channels and then emitted as hot scav-
enging air onto the glass. The hot air rinses the glass and keeps it soot-free.
The tertiary channel, which can be seen at the the top of the combustion chamber to-
wards the back, serves to combust the final gas residues.
By setting the interval between position 1 and 2, the energy content in the firewood is used
optimally, as there is oxygen for combustion and for the burning of the pyrolysis gasses.
When the flames are a clear yellow the damper has been set correctly. Finding the correct
position comes with time after you have used the 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.
