*2 Calculation values for sizing the flue gas system to EN 13384.
Flue gas temperatures measured as gross values at 20 °C combustion air temperature.
The flue gas temperature at a return temperature of 30 °C is significant for the sizing of the flue system.
The flue gas temperature at a return temperature of 60 °C is used to determine the application range of flue pipes with maximum permissible
operating temperatures.
