Values according to EN 677.
*2
If the gas supply pressure is higher than the maximum permissible value, a separate gas governor must be installed upstream of
the system.
*3
Minimum pressure for cold water connection 1 bar.
*4
Values for sizing the flue system to DIN 4705.
Flue gas temperatures are gross values measured at 20 °C combustion air temperature.
The data for the partial load refers to an output of 30 % of the rated output. Where the partial load differs (depending on the operat
ing mode of the burner), the flue gas mass flow rate must be calculated accordingly.
The flue gas temperature at a return temperature of 30 °C is the criterion for sizing the flue system.
The flue gas temperature at a return temperature of 60 °C is used for determining the application range of flue pipes with maximum
permissible operating temperatures.
