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 TRI-
GON XXL SE, EVO and ECO 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 modula-
tion 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.
