1. When codes of practice dictate the use of terminal guards, they can be obtained from most Plumbers' and Builders' Merchants.
2. There must be a clearance of at least 50mm between any part of the terminal and the guard.
3. When ordering a terminal guard, quote the appliance name and model number.
4. The flue terminal guard should be positioned centrally over the terminal and fixed as illustrated.
8.10 Flue Deflector (Fig. 21)
1. If required, push the flue deflector over the terminal end and rotate to the optimum angle for deflecting plume. Secure the deflector to the terminal with screws provided.

8.11 Plume Displacement Kit (Fig. 21b)
Kit No 5118638
Content of kit
1 0.9m 60/100 Concentric Flue
1 1m 60 Dia Exhaust Flue Pipe
1 Adaptor
2 60 Dia Support Brackets
1 93° Elbow/Plume Outlet Assembly
1 Flexible Flue Trim
3 "O" Rings
1 'Jubilee Clip
1 Elbow
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 'peak' uppermost to prevent rain entry (Figs. 21c & 21d), and be at least 2 metres above ground level. It
must be secured as shown in Fig. 15a. The plume outlet must also be at least 500mm from the air inlet in any direction (Fig. 21d).
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:­ 5 metres
Additional bends 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. 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.
