Important
Please contact us for different configurations (specials). We also
provide in-depth advice on the choice of flue gas outlet material
and control engineering, including for non-standard configurations.
If you want to decide on the position of the boilers and the configuration
yourself, choose an independently installed cascade system. Be sure to
use De Dietrich cascade components.

Main pipes
The main pipes consist of: main supply, return and gas pipes.
By connecting main pipes, it is possible to extend the system to a maxi
mum of 8 boilers in a linear configuration or 2 x 4 boilers in a back-to-back
configuration.
In a linear configuration, the rear connections must be capped off using
the caps supplied. In a back-to-back configuration with an odd number of
boilers, the unused connections must also be capped off.
Diameter of supply and return pipes 100 mm:
Main pipes for 2 (4) boilers with gas pipe DN 65
Main pipes for 3 (6) boilers with gas pipe DN 65
