Above all it is necessary to provide the PERFECT AIRFLOW (draft) in pipes for smoke exhaustion that
has to be free, without any obstacles, such as different narrowing or corners. All displacements of the axis
must have a tilted orbit with a maximum angle of 45 degrees from the vertical, while 30 degrees is the
best solution. This displacement would be best done near the top of the chimney resistant to the wind.
According to the regulations (the top of the chimney resistant to wind, distance, and placement of
the stove ) the distances shown in Table 3 must be met:
Roof slope:
The distance between the ridge and the
chimney cap
Minimum height of the chimney measured at
the top slot (at the back of the chimney)

However, it is required to provide an initial vertical extension of 1,5 m (minimum) in order to
provide proper discharge of smoke.
