Flue gas parameters
Calculation values for sizing the flue system to EN 13384. Flue gas
temperatures as actual gross values at 20 °C combustion air temper-
ature.
Flue gas category to G 635/G 636

– At partial load
Flue gas temperature at a return temperature of 60 °C (used to deter-
mine the application range of flue pipes with max. permissible operat-
ing temperatures)

Information regarding the max. permissible gas supply pres-
sure
If the gas supply pressure is higher than the maximum permissible
value, install a separate gas pressure governor upstream of the sys-
tem.

Note on connection values
The connection values are only for reference (e.g. in the gas con-
tract application) or for a supplementary, rough estimate to check the
volumetric settings. Due to factory settings, the gas pressure must
not be altered from these values. Reference: 15 °C, 1013 mbar
(101.3 kPa).
