1. This kit is recommended for installations where the
condensate plume emitted from the flue may cause a nuisance
'Jubilee' Clip
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 'peak' uppermost to prevent rain entry (Figs. 15 &
16), and be at least 2 metres above ground level. It must be
secured as shown in Fig. 10. The plume outlet must also be at
Fig. 14
least 500mm from the air inlet in any direction (Fig. 16).
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 (24/32 models)
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°
Fig. 16
& 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.
