3.8 Flue termination
The following details refer to both flue systems.
a.The terminal must be positioned such that the produc-
ts of combustion can disperse freely at all times.
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 fitted less than 2 m above a balcony,
above ground or above a flat roof to which people
have access then a suitable terminal guard must be
provided and fitted (made by Tower Flue Components,
Tonbridge, TN9 1TB).
