2.6.7. Recommendations of Plume Kit
Installation
NOTE: Due to the nature of the boiler a plume of water
vapour will be discharged from the flue. This should be
taken into account when siting the flue terminal.
1. The following guidelines indicate the general
requirements for siting balanced flue terminals. For
GB recommendations are given in BS 5440 Pt 1. For
IE recommendations are given in the current edition of
I.S. 813 “Domestic Gas Installations”.
2. If the terminal discharges onto a pathway or
passageway, check that combustion products will not
cause a nuisance and that the terminal will not obstruct
the passageway.
3. If a terminal is less than 2 metres above a balcony,
above ground or above a flat roof to which people
have access, then a suitable terminal guard must be
provided.
4. *Reduction to the boundary is possible down to 25 mm
but the Plume Displacement Kit Bend (45°) (part no.
153.11.660.6000 33) must be fitted.

IMPORTANT:
• Under car ports we recommend the use of the plume
displacement kit.
• The terminal position must ensure the safe and
nuisance - free dispersal of combustion products.
IMPORTANT:
If fitting a Plume Displacement Flue Kit, the air inlet must
be a minimum of 150mm from any opening windows or
doors)
