4.5.2 Maximum flue length
Vertical: 9 meters is the maximum length between the heater and its flue outlet.
Horizontal: 6 meters is the maximum length between the heater and the flue outlet.
When bends are used, the pressure drop will increase and therefore a 90° bend will count as 2
meters and a 45° bend as 1 meter. For further information regarding the flue system, please
contact your supplier.
4.5.3 Flue terminals
The following flue terminals are allowed:
Vertical discharge
Horizontal discharge

4.5.4 Condensation in the discharge system
During heating up, it is possible that condensation is formed in the discharge system. This
however, will evaporate if the heater is operating for a longer period of time.
If the straight length of the discharge flue is longer than 4 meters this condensation will not
evaporate again and accumulate in the heater! Isolation of the discharge pipes or a
condensation trap just at the heater is then absolutely necessary.

This condensate will most likely not be formed on heaters more than 20kW.
