The used material must compliant with the following standards:
EN1856 for metal materials (Stainless steel and aluminum)
EN14471 for plastic materials.
The maximum horizontal flue gas way is 20m. With horizontal ways longer than 20m, a faultless burner start in cold condi-
tion can not be guaranteed.
The maximum negative flue pressure, which does not affect the burner modulation ratio, is 30Pa. Higher negative pressure
will lead to limitation of the burner modulation ratio.

The flue gas system has to be desi-
gned and calculated to guarantee
that the correct materials are used
and that the boiler can work cor-
rectly.
The following table shows the maxi-
mum vertical flue length in combi-
nation with 1 bend, maintaining the
flue resistance below 200Pa.
The table is only an indication of the
possible length. Calculation done
with rigid tube and exit without cap
("free" opening).
In order to choose the correct flue
material, the maximum flue pres-
sure has to be calculated. Below
table shows the different pressure
classes and their limits.
