The appliance produces a white wisp of condensation (pluming). This wisp of condensation
is harmless, but can be unattractive, particularly in the case of outlets in outside walls.
At this time there are 2 different ways of connecting the ue gas/air intake system,
parallel or concentric. See chapter 7.1 and 7.2 how to convert the boiler connection to
the desired option.

Maximum ue length for individual ue gas outlet table 7.4.b
100/150 = 350mm
Dismantlement and shorten pipes gure 7.4.b
Example:
An UB 70 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 -1.1 ) = 22.8
meters.
Cutting the concentric pipe goes as follows:
- Take out the inner tube by turning it until it releases from its security position;
- Cut just as much from the air intake part as from the ue gas part;
- Take off the burrs from the cutting edge to prevent cutting the seals;
- Click the pipes back together again.
Use special grease to simplify the tting
When mounting the ue gas system, pay attention to the ow direction. An arrow on the
product points this out. It is not permitted to mount a system upside down and will lead
to complaints.
Refer to table 7.4.b for maximum applicable pipe length.
