Flue gas system
Dimensioning
Dimensioning
When dimensioning a flue gas system, it’s necessary to perform a calculation
check of the flue gas system in order to verify if the choosen system is applicable.
The following tables represent as an example of possible flue gas systems of
R3400 EVO, R3500 EVO and R3600 EVO series, including the maximum
possible height of the system. These examples only give an indication of the
possible heights, but they can not be used for official flue gas layout calculation.
Each flue gas system must be calculated by an authorized company.
The maximum negative flue gas pressure, which doesn’t affect the burner
modulation ratio, is 30 Pa. Higher negative pressure will lead to limitation of the
burner modulation ratio.
The maximum horizontal flue gas way is 20m. With horizontal ways longer than
20m, a faultless burner start in cold condition can not be guaranteed.
