Chimney flue
The chimney flue is the wood-burning stove’s engine, and of vital importance to the stove’s general functi-
on. The draught in the chimney flue generates negative pressure in the stove. It removes smoke from the
stove and draws in air through the air slider which cleans the glass pane and keeps it free from soot. The
negative pressure also ensures that air for combustion is drawn in through the primary and secondary
sliders.
The chimney draught is generated by the different temperatures inside and outside the chimney. The
higher the temperature in the chimney, the stronger the draught. That’s why it is particularly important
that the chimney is thoroughly heated before pushing the slider forwards and shutting off the air for the
combustion in the stove (a brick-lined chimney takes longer to heat than a steel flue). On days on which
the draught in the chimney is weak due to wind and weather conditions, it is particularly important to heat
up the chimney or flue as quickly as possible. The flames must be generated quickly. Chop the wood up
particularly small and also use kindling wood.
After long periods when the stove has been out of use, it is important to have the flue pipe checked for any
blockages.
It is possible to connect several devices to one chimney. However, the applicable rules for this must first
be looked into.
Malfunctions can occur even in a top-class chimney if it is not operated correctly. Inversely, a chimney of
a lesser quality can operate extremely well if used properly.
Chimney sweeping
To counter the risk of a chimney fire, the chimney should be swept every year. The flue pipe and smoke
chamber above the steel baffle plate should be cleaned at the same time as the chimney. If the chimney is
too tall for it to be cleaned from the top, a cleaning vent should be installed.
In the event of a chimney fire, close all vents and call the fire brigade immediately. Before using the stove
again, have the chimney inspected by a chimney sweep.
