Forhorizontalsections,theoutletsystemshouldalwaysbettedonanincline(50mm/m)
sloping down towards the appliance so that no condensation water is able to accumulate
in the outlet system. The chances of icicles forming on the roof outlet is minimised
by causing the condensation water to run back towards the appliance. In the case of
horizontaloutletstheinletsystemshouldbettedonaninclineslopingdowntowards
the outside to prevent rainwater from coming in.
The appliance produces a white wisp of condensate (plumeing). This wisp of condensation
is harmless, but can be unattractive, particularly in the case of outlets in outside walls.
For wall terminals a plume management kit is available as an option.
Cutting the pipe goes as follows:
- Cutjustasmuchfromtheairintakepartasfromtheuegaspartusingahandsaw;
- Takeo󰀨theburrsfromthecuttingedgetopreventcuttingtheseals;
Whenmountingtheuegassystem,payattentiontotheowdirection(Seegure7.4.c).
It is not permitted to mount a system upside down and will lead to complaints.
Useasoapsolventorspecialgreasetosimplifythetting.
Refer to table 7.4.a for maximum applicable pipe length.

Maximum ue length for individual ue gas outlet table 7.4.a
Example:
An XL70 with a
concentric ue gas system
ø100/150mm has according
to the table a maximum ue
straight length of 25m In the
system that is going to be put
in there are 2 x 45° bends, so
the maximum ue gas length
is
25 – ( 2 x -1.3) = 22.4
meters.
