Kit No 5121371
Content of kit
1 70/110 Concentric Flue
11m 70 Dia Exhaust Flue Pipe
2Support Brackets
193° Elbow/Plume Outlet Assembly
1Flue Trim
2“O” Rings
1Elbow with Gasket
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 outlet connection upwards.
3.The 70Ø pipe connects to the outlet of the concentric terminal assembly. The elbow/plume outlet must be fitted to the end of the 70Ø pipe.
NOTE: The plume outlet must always be at least 45° to the wall, with the ‘peak’ uppermost to prevent rain entry (Figs. A & B), and be at least 2 metres above ground level. It must be secured as shown in Fig. C.
The outlet must be positioned so that any condensate plume is directed away from adjacent surfaces.
4. | It is possible to reduce or increase (with the addition of |
extensions) the length of either or both the 70/110 concentric | |
and 70Ø 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 boiler flue elbow. There is a |
further 45mm engagement into the elbow. |
IMPORTANT: The maximum equivalent length of
concentric flue is:- 4 metres
Additional elbows may be fitted in the concentric flue, but the equivalent length must be reduced by 1 metre (93° elbow) or 0.5 metres (45° elbow).
7.70Ø 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. 70Ø 93° elbows are equivalent to 3.5 metres of straight length and 45° elbows to 1 metre.
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 &
Outlet Connection

Servicing Instructions and BS5440 Pt. 1. It is NOT necessary to fit a terminal guard over the air inlet or the plume outlet.
