Flue gas parameters
Flue gas category to G 635/G 636
Temperature (at a return temperature of 30 °C)
– at rated heating output
– at partial load
Temperature (at a return temperature of 60 °C)
Mass flow rate
Natural gas
– at rated heating output
– at partial load

Available draught
*7 If the gas supply pressure is higher than the maximum permissible value, install a separate gas pressure governor upstream of the system.
*2 Calculation values for sizing the flue system to EN 13384.
Flue gas temperatures as actual 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.
