Flue gas system
Requirements and regulations
Materials
Requirements and regulations
Regulations for the construction of flue
gas systems are very different for each
country. It should be ensured that all
national regulations with regard to flue
gas systems are respected. The most
important national norms can be found
in the chapter „Norms“.
A separate condensate drain for the
chimney is not necessary, as the
condensate can enter the drain via the
syphon connection of the boiler.
Materials
Exclusively materials, which are heat
resistant and resistant to flue gases and
aggressive condensate, may be used.
The R3456 EVO has an integrated high
limit thermostat function for the flue
gases. When the max flue gas
temperature is exceeded, the burner is
switched off. With this function, an
additional (external) safety device is not
necessary.

The installer is responsible to apply the
correct diameter, length and type of flue
gas system. If any questions arise during
the calculation contact your local
manufacturer office for more information.

Pay attention to the following
recommendations when
dimensioning a flue gas system:
-
Only approved flue gas material
may be used.
-
The flue gas system must be
properly calculated to ensure a
safe functioning of the system.
-
Flue gas system components
should be removable for
maintenance purposes.
-
Horizontal flue gas ways must be
mounted under an angle of 3º
minimum.
