Convection
RAIS/
attika
stoves are convection stoves. The means that the external panels of the
stove are not over-heated. Convection means there is air circulation which ensures that
the heat is distributed more evenly through the entire room.
The cold air is sucked in at the base of the stove up through the convection channel,
which runs along the stove’s combustion chamber.
The
heated
air flows out of the top of the stove, and thus ensures circulation of hot air
in the room.
Note however, that all exterior surfaces become hot during use – therefore, please
exercise extreme care.
Chimney
The chimney is the driving force that allows the wood-burning stove to function. Re-
member that even the best wood-burning stove cannot function optimally if there is no
necessary and correct draught in the chimney.
The chimney height must be sufficient to ensure the correct draught of 12–18 pascal.
If the recommended chimney draught cannot be achieved, problems may occur with
smoke coming out of the door when heating. RAIS recommends that the chimney is
adjusted to the flue collar. The length of the chimney, measured from the top of the
stove, should not be shorter than 3 metres, and reach at least 80 cm above the build-
ing’s roof ridge. If the chimney is located on the side of the building, the top of the
chimney should never be lower than the roof ridge or the highest point of the roof.
Note that there are often national and local provisions for buildings with thatched
roofs.
The stove is suitable for connection to shared flues (although only if the stove is con-
nected to a fresh air supply), but we recommend the inlets are positioned such that
there is a free-height difference between them of at least 250 mm.
The flue collar has a diameter of 150 mm.
If the draft is too high, we recommend equipping the chimney or flue pipe with an
adjusting damper. If this is installed, you must ensure a free flow area of at least 20
cm² with closed adjusting damper. This means that the energy in the fuel is not used
optimally.
If you are in any doubt about the state of the chimney, you should contact a chimney
sweep.
Remember, there must be free access to the cleanout door on the chimney.
