3.7 Flue
termination
The following information applies to both flue pipe
systems.
a. The terminal position must be located in such a
position that any flammable gasses can be freely
dissipated.
b. A plume of water vapour will sometimes be visible
from the flue terminal. Positions where this could be a
nuisance should be avoided.
c. If the terminal is less than 2 m above a balcony, the
ground or a flat roof that is accessible by persons, a
suitable terminal guard should be fitted (manufactured
by Tower Flue Components, Tonbridge, TN9 1TB, Model
K3, plastic-coated).

that ignition or damage to sections of the building are
avoided.
