The dimensioning of flue gas
systems or chimneys depends on the
fireplaces to be connected to it. The
resulting efficiency of a flue gas
system is, however, subject to natural
fluctuations due to temperature
differences between the seasons
and the weather conditions. To ensure
safe operation operation, the flue gas
systems for an assumed outside
temperature of 15 Gr. C (according to
EN 13384). During the heating period,
when the systems are mainly in operation,
the unfavourable temperature gradient
can result in excessive negative pressure
in the system. As a result, combustion is
fuelled in an inefficient manner. The
efficiency deteriorates and energy
consumption increases. Draught limiters
limit the negative pressure to the optimum
value for the fireplace.
