1. This kit is recommended for installations where
the condensate plume emitted from the flue may
cause a nuisance or affect the surroundings.
2. The terminal must be positioned outside the
building with the air inlet facing downward and outlet
connection upwards.
3. The plume outlet must always be at least 45° to
the wall, with the

uppermost to prevent rain
entry (Fig. 6b), and be at least 2 metres above
ground level. It must be secured with the support
brackets.. The plume outlet must also be at least
500mm from the air inlet in any direction (Fig. 6b).
NOTE:
The outlet must be positioned so that any
condensate plume is directed away from adjacent
surfaces. There must be a constant fall along the
entire length of the flue system from the outlet
back to the boiler.
4. It is possible to reduce or increase (with the
addition of extensions) the length of either or both
the 60/100 concentric and 60Ø exhaust.
5. Standard concentric flue extension kits may be
added between the boiler elbow and the terminal
assembly.
6. The minimum length of the concentric flue is
100mm when measured from the edge of the flue
elbow.
IMPORTANT:
The maximum equivalent length of
concentric flue is:-
8 metres
Additional bends may be fitted in the concentric
flue, but the equivalent length must be reduced
by 1 metre (93° bend) or 0.5 metres (45° bend).
7. 60Ø 1 metre extensions (including support
bracket), and additional 93° & 45° elbows are
available. Any additional 93° & 45° elbows must be
accounted for when calculating flue lengths.
NOTE:
Permitted positions of the plume outlet
relative to doors, windows etc. are the same as
for conventional concentric flues as detailed in
the main Installation & Servicing Instructions and
BS5440 Pt.1. It is
NOT
necessary to fit a terminal
guard over the air inlet or the plume outlet.
