4.5 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 gases can be freely

dissipated.

b) A plume of water vapour will sometimes be visi-

ble 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 fit-

ted (manufactured by Tower Flue Components,

Tonbridge, TN9 1TB, Model K3, plastic-coated).

that ignition or damage to sections of the building are

avoided.
