Table 7 and Table 8 for co---axial pipes ø 60---100 mm,
Table 9 for co---axial pipes ø 80---125 mm and in the
diagrams for the ø 80 mm twin pipes air---flue systems.
Refer to the assembly instructions contained within the
chosen flue kit packaging for the correct assembly and
installation.
Condensate Collection
When a length of vertical pipe is used in the system and the
length of flue exceeds the following, a condensate drain and
trap must be fitted to the lowest point of the system.
The trap must be connected to a suitable waste pipe.
ø80---125mm co---axial pipes --- 1 metres
ø80 twin flue pipes --- 7 metres
