Prior to installation of stove, check chimney draught since it is one of key factors for
proper operation. Draught depends on integrity of the chimney and meteorological
conditions.
One of the simplest ways for checking of draught in chimney is by candle flame, as
described on figure 3. Candle flame is to be put close to adaptor opening of chimney
and if it flickers toward opening, draught is satisfactory (figure 3.2). Weak flickering of
the flame is indicator of weak draught (figure 3.1).
Figure 3.1 Figure 3.2
If draught in chimney is weak (Figure 3.1), check correctness of the chimney.
Chimney should be located in the interior of the room, and id it is on external walls of
the room, chimney insulation is highly recommended.
Faults of the chimney may be (figure 4.1):
1. Weak windshield,
2. Strange body or bulges in the chimney,
3. Chimney chaps,
4. Accumulated tar,
5. Non-tightness of adapters and cleaning openings,
6. Smoke pipe installed too deep,
7. Fireplace without door or some other opening on chimney and non-tightness
of connecting and other cleaning openings.
8. Non-tightness of connecting and cleaning openings.
Distance between two adapters on the same chimney must be minimum 50 cm
(Figure 4.2).
On figure 4.2 example of proper chimney is described.
Devices which use gas as a fuel may not be connected to the very same
chimney.
