Standard Horizontal Flue
10.6 Flue Length
The maximum permissable horizontal flue length is 10 metres
plus the flue terminal assembly, this can be achieved by use
of the accessories, see diagram 10.12.
However should additional 90o or 2 x 45o elbows be used
then the length MUST be reduced by 1metre.
The diagram 10.10 shows the length achievable by using the
kit A2043400.
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.
