3.5.1 Flue termination
The following details refer to both flue systems.
1. The terminal must be located where the combustible substances can escape freely at all
times.
2. A plume of water vapour will sometimes be visible from the flue terminal. Positions
where this could be a nuisance should be avoided.
3. 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, Model K3, plastic coated).
NOTE:
Vertical flues must not terminate within 600mm of an openable window, air vent or any
other ventilation opening.
The flue assembly shall be so placed or shielded as to prevent ignition or damage to any part of
the building.
