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 appli-
cable.
The following table shows two
examples of possible flue gas systems,
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 pres-
sure, which doesn’t affect the burner
modulation ratio, is 30 Pa. Higher nega-
tive pressure will lead to limitation of
the burner modulation ratio.
The maximum horizontal flue gas way
is 20 m. With horizontal ways longer
than 20 m, a faultless burner start in
cold condition can not be guaranteed.
