Flue terminal position
(cont.)
Flue Terminal Location
Detailed recommendations for
flue installation are given in BS
5440:1. The following notes are
for general guidance.
n
It is important that the position
of the terminal allows free
passage of air across it at all
times.
n
It is essential to ensure that
products of combustion
discharging from the terminal
cannot re-enter the building
or any other adjacent building,
through ventilators, windows,
doors, other sources of
natural air infiltration or forced
ventilation / air conditioning.
n
The minimum acceptable dimensions
from the terminal to obstruction and
ventilation openings are specified above
(BS 5440 Part 1).
n
If the terminal discharges into a pathway
or passageway check that combustion
products will not cause nuisance and
that the terminal will not obstruct the
passageway.
n
Where the lowest part of the terminal
is fitted within 850 mm of a plastic or
painted gutter, or 450 mm of painted
eaves, an aluminium shield at least 750
mm long must be fitted to the underside
of the painted surface.
n
Where the terminal is fitted within 850
mm of a plastic or painted gutter, or 450
mm of painted eaves, an aluminium
shield at least 750mm long must be fitted
to the underside of the painted surface.
n
The air inlet / flue outlet duct must not
be closer that 25 mm to combustible
material.
n
Due to the high efficiency of the boiler
the terminal may emit a plume of vapour.
This is normal but positions where
this would cause a nuisance should be
avoided.
