the position of the house (due to hillside
position or different building heights, drop
winds or dynamic pressure zones arise)
Position of the chimney on the roof (chimney
opening must be at least 0.5 m above the
highest point of roofs with an angle of
inclination of more than 20° or at least 1.0 m
away from roof surfaces with an angle of angle
of 20° or less)
Design of the chimney opening (decorative

In practice, it may happen that a chimney builds up
too high a delivery pressure continuously or
sometimes (due to changes in the weather, gusty
wind etc.). By installing a draft regulator, the burn-
up conditions can be kept almost constant, which
improves the efficiency. However, it is always
better to consult the responsible chimney specialist
at the planning stage!
Attention:
The whole chimney system must be installed in
accordance with the valid EN 13384 standard.
Incorrectly dimensioned chimney systems can lead
to malfunctions (dangerous situations).

B

D

E

allowable delivery pressure (previously referred to
as drawbar requirement) 2 mm WS = 0.2 mbar
Effective chimney height = height difference
between the exhaust gas inlet into the chimney and
the chimney outlet (according to EN 13384).
This calculation of the whole chimney system must
be made by the chimney supplier or an authorised
company.
