OPERATING PROBLEMS RELATED TO DRAUGHT DEFECTS IN THE CHIMNEY
Among all the weather and geographical conditions that affect chimney operation (rain, fog, snow,
altitude a.s.l., exposure to sunlight, orientation to the cardinal points, etc.), the wind is certainly the most
determinant. In fact, besides the thermal depression caused by the difference in temperature between
inside and outside the chimney, there is another type of depression (or overpressure): dynamic pressure
caused by the wind. An updraft always increases depression and therefore the draught. A horizontal wind
increases depression provided the chimneypot has been installed properly. A downdraft always decreases
depression, at times inverting it.

Besides the direction and force of the wind, the position of the chimney and the chimneypot with respect
to the roof of the building and the surrounding landscape is also important.
The wind also affects chimney operation indirectly by creating overpressure and depression zones within
the building as well as outside. An internal overpressure can be created in rooms that are directly exposed
to the wind (2), which can enhance the draught in stoves and fireplaces, however, it can be counteracted
by the external overpressure if the chimneypot is situated on the side exposed to the wind (1). On the
other hand, a dynamic depression can be created in rooms that are opposite the wind direction (3),
which competes with the natural thermal depression generated by the chimney, however, this can be
compensated for (sometimes) by placing the smoke duct opposite the wind direction (4).
IMPORTANT!
The operation of the pellet product is significantly affected by the chimney layout and
position.
Hazardous conditions can only be resolved by qualified personnel setting the product
appropriately.
