1 An opening means an openable
element, such as an openable
window, or a permanent opening
such as a permanently open air vent.
2 Notwithstanding the dimensions
above, a terminal should be at least
300mm from combustible material,
e.g. a window frame.
3 A way of providing protection of
combustible material would be to fit
a heat shield at least 750mm wide.

FLUE TERMINAL POSITIONS
• The flue must be fitted and terminated in
accordance with the recommendations of
BS 5410.
• Flue terminals must be positioned to avoid
combustion products entering into buildings.
• The flue must not cause an obstruction.
• Discharge from the flue outlet must not be a
nuisance.
• Flue gases have a tendency to plume and in
certain weather conditions a white plume of
condensation will be discharged from the flue
outlet which could be regarded as a
nuisance, for example, near security lighting.
• There should be no restriction preventing the
clearance of combustion products from the
terminal.
• The air inlet/outlet duct and the terminal of
the boiler must not be closer than 25mm to
any combustible material. Detailed
recommendations on protection of
combustible materials are given in BS 5410:1
• A protective terminal guard must be fitted if
the terminal is 2m or less above a surface
where people have access.
The guard must be spaced equally (minimum
50mm) around the flue and fixed to the wall
with plated screws.
Stainless steet terminal guard:
Part No. 7 716 190 050.
• The following additional guidelines (from part
L Exceptions Guidance Document) are
recommended when determining the flue
outlet position:
• Avoid discharging flue gases into car ports
or narrow passageways.
• *Minimum distance of the flue terminal from
above ground is 2100mm where directed to a
public footpath, private access route or a
frequently used area and 2500mm from a
car parking area.
• **Minimum distance of the flue terminal to a
facing wall, fence, building or property
boundary is 2500mm.
