7.0 SITE REQUIREMENTS
7.7 FLUE
1. This high efficiency boiler will discharge a plume of water
vapour from the flue. This should be considered when siting
the flue terminal.
2. 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”.
3. 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.
4. 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 - Part No: 951507.
IMPORTANT:
• Only
ONE
of the 25mm clearances (Positions ‘O’ to ‘S’ in
the chart below) is allowable per installation.
• 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.

NOTE: The minimum distance from a flue terminal to a boundary line is 300mm.
If fitting a plume div
e
erter kit, the air inlet should be a minimum of 100mm from
any opening windows or doors.
NOTE A: A term
inal should
be no closer than 150mm
to an opening in the
brickwork intended to
accommodate a fitt
i
ing
such as a window frame.
NOTE: Fitting of the deflector
elbow is recommended when
installing boil
e
er to minimum
clearance of 25mm as
detailed in positions O & P.
