10.1 Appliance
The S-CBX boilers have an internal flue gas valve for an
overpressure system according to below table. This device is
needed to prevent recirculation of the flue gases.

Remark 1: DN 150/200 means: the diameter of the horizontal collector including the bend = 150 mm and after
the bend the diameter of the vertical section is 200 mm with an adaptor of 150->200 mm
Remark 2: Horizontal length between shaft and last collector = 1 m. Greater length decreases the maximum
vertical length of the table.
Remark 3: For calculating other lengths between the last collector and the bend, the length of the vertical
height must be reduced by the number of length and for bends the following table must be used.
