10.1 Flue Length
The maximum permissable horizontal flue length is 8 metres
plus the flue terminal assembly, this can be achieved by use
of the accessories, see diagram 10.3.
However should an additional 87.5º or 2 x 45º 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 flue system must be
designed to have a continuous fall to the boiler of at least 2.5º
44mm/metre to allow condensate to run back into the boiler
and out via the condensate drain.
The flue can be installed from inside the building, when
access to the outside wall face is not practicable.

10 Telescopic Flue - Length, Preparation and Installation
Multiple Boiler Chimney Flue Length
The flue length must be calculated and installed according to
the relevant standards EN 13384-1 and 2 (C43 flue systems
only) with reference to the table below and the manufacturers
instructions supplied.
The appliance maximum flue length must be included when
calculating the overall design of the flue system.
NOTE:
The horizontal flue terminal must be removed, see
diagram 10.2.
