Outlet systems
Please note that not all flue gas configurations described below are permitted in all
countries. Therefore observe local regulations prior to installation.
5.6.1
Pipe lengths
As the resistance of the flue tube and air supply pipes increases, the power of the unit
will decrease. The maximum permitted power reduction is 5%.
The resistance of the air supply and the combustible gas outlet depends on the length,
diameter and all components of the pipe system. Per unit category, the total permitted
pipe length has been indicated for the air supply and the combustible gas outlet.

General assembly:
For all outlets, the following assembly applies:
1.
Slide the concentric combustion gas outlet pipe and air supply pipe.
2.
Slide the concentric pipes into each other.
From the unit, every pipe has to be slid into the previous one.
3.
Mount a non-vertical combustion gas outlet pipe on a slope towards the unit
(min. 5mm/m).
4.
Fit the assembly brackets in accordance with the assembly instructions of the
supplier of the air supply/flue tube system.
