Convection

attika
RAIS/ stoves are convection stoves. Accordingly, the external stove panels must
not become overheated. Convection means that the air is circulated in the room so that
heat is evenly distributed.
The cold air is drawn at the base of the stove up through the convection channel and
flows into the stove's combustion chamber.
The heated air flows out of the oven top, and ensures warm air circulation in the
room.
Please note that you must use extreme care as all exterior surfaces become hot during
the stove's use.

Chimney

The chimney is the driving force which makes the stove function. However, not even
the best stoves could function correctly without the necessary and proper draught in
the chimney.
The chimney height must be sufficient to ensure the correct draught of 14 to 18 Pa. If
the chimney draught is lower than recommended, smoke may leak into the room when
the stove is lit. RAIS recommends to adjust the chimney height with the flue pipe neck.
The chimney length, starting from the top of the stove, should not be shorter than 3
meters and be at least 80 cm above the ridging. For chimneys placed along the house
sides, the chimney's top should never be lower than the roof ridge or roof's highest
point.
Note that national and local regulations on houses often have provisions for thatched
roofs.
You should also familiarise yourself with the draught conditions for chimneys with 2
flues.
While the stove is suitable for connection with the flue gas collector, we recommend to
place inlets to ensure a minimum ground clearance between them of at least 250 mm.
The flue outlet socket should be 150 mm in diameter.
For strong draughts, the chimney should be fitted with a draught damper. In which
case, it is important to ensure that there is a free flow -through area of minimum 20
cm² when the regulating damper is shut. Otherwise, the fuel energy may not be used
optimally.
If you are in doubt about the condition of the chimney, please contact a chimney
sweep.
Remember that access to the soot door on the chimney should be kept clear.
