10.1 Flue Length
The maximum permissible horizontal ue length is 10 metres
plus the ue terminal assembly, this can be achieved by use
of the accessories, see diagram 10.3.
However should an additional 87.5
o
or 2 x 45
o
elbows be
used then the length MUST be reduced by 1metre.
The diagram 10.1 shows the length achievable by using the
kit A2043600.
When extension pipes are used the ue system must be
designed to have a continuous fall to the boiler of at least 2.5
o
44mm/metre to allow condensate to run back into the boiler
and out via the condensate drain.
The ue can be installed from inside the building, when
access to the outside wall face is not practicable.
