2.2 Flue Length
The maximum permissable horizontal flue length is 10metres
plus the flue terminal, this can be achieved by use of the
accessories, however should additional 90
o
or 2 x 45
o
elbows
be used then the length MUST be reduced by 1metre.
When extension pipes are used the flue system must be
designed to have a continuous fall to the boiler of at least 2.5
o
to allow condensate to run back into the boiler and out via the
drain.
The flue can be installed from inside the building, when access
to the outside wall face is not practicable.
The diagrams 2.1 to 2.4 describe the lengths achievable
without the use of extensions or elbows.
