For horizontal sections, the outlet system should always be fitted 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 fitted 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 flue gas part using a hand saw;
- Take off the burrs from the cutting edge to prevent cutting the seals;
When mounting the flue gas system, pay attention to the flow direction (See figure 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 fitting.
Refer to table 7.4.a for maximum applicable pipe length.

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