Drying And Storage; Regulating The Combustion Air - attika V I S I O 2 Bedienungsanleitung

ONLY USE RECOMMENDED FUELS
the following table shows the calorific value of different types of wood, which have been
stored for 2 years, and which have a residual moisture of 15-17%.
Wood
hornbeam
beech and oak
ash
maple
birch
mountain pine
fir
poplar
1 kg of wood yields the same heat energy irrespective of wood type.
1 kg beech merely takes up less space than 1 kg of fir.

Drying and storage

Drying wood takes time. proper air drying takes approx. 2 years.
here are some tips:
• Store the wood sawn, split and stacked in an airy, sunny place, which is protected
against rain (the south side of the house is particularly suitable).
• Store the firewood stacks at a hand's breadth apart, as this ensures that the air flow-
ing through takes the moisture with it.
• avoid covering the firewood stacks with plastic, as this prevents the moisture from
escaping.
• It is a good idea to bring the firewood into the house 2-3 days before you need it.

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 (next section).
the primary air is added to the primary combustion zone at the bottom of the burning
chamber, i.e. the bed of glowing embers. this cold air 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 and is pre-heated through the
side and back 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, 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 regular use of the stove.
