The flue must be fitted and terminated in
accordance with the recommendations of
BS5440 : Part 1.

The flue must not cause an obstruction.

certain weather conditions a white plume of
condensation will be discharged from the
flue outlet. Where this could be a nuisance,
for example, near security lighting, an alter-
nate position should be found.

Detailed recommendations on protection of

A protective terminal guard must be fitted if
the terminal is 2m or less above a surface to
which people have access.
The guard must be spaced equally (mini-
mum 50 mm) around the flue and fixed to
