of the house, these must be ventilated so that up to 40 m

of air inflow is ensured;
• Do not use a mesh on the top of a chimney because it can reduce draught and cause problems for the stove functioning;
• When designing the chimney piping for the stove, do not use more than 3 pieces of 90° bends. The biggest distance between the
adjacent bends must not exceed 2,5 meters horizontally;
• If the stove is installed near non-flammable walls, a minimum distance of 10 cm should be left from the rear stove panel to the wall.
This distance must be increased to 20 cm, if the wall is covered with flammable finish. In either case, a 50 cm free space must be left
from lateral sides of the stove and 150 cm- from the front side. It is recommended to increase the mentioned distances further, if
very easily flammable objects like curtains are present in the vicinity of the stove.

Ashes accumulate in the 90° bend
• PATTERNS OF INSTALLATION
A 90° bend should not be installed as the first
connecting part – ashes would quickly obstruct a
passage for smoke causing unexpected problems
for draught of the flue (Fig 4).
This type of installation (Fig. 3) requires an
insulated flue, as the whole smoke pipe is
installed outside the house. A chimney tee with
an inspection cap and condensate drain pipe is
mounted in the lower part of the flue.
