If the gas supply pressure is higher than the maximum permissible value, install a separate gas governor upstream of the system.
*3
Minimum pressure of the cold water connection 1 bar.
*4
Calculation values for sizing the flue gas system to EN 13384.
Flue gas temperatures measured as gross values at 20 ºC combustion air temperature.
The details for partial load refer to an output of 30 % of rated output. Calculate the flue gas mass flow rate accordingly when the
partial load differs from that stated above (subject to the burner mode).
The flue gas temperature at a return temperature of 30 ºC is decisive for sizing the flue gas system.
The flue gas temperature at a return temperature of 60 ºC is used to determine the application range of flue pipes with maximum
permissible operating temperatures.
