8.8 Terminal Guard ( Fig. 19 )
1. When codes of practice dictate the use of terminal guards, they can be obtained from most Plumbers' and Builders' Merchants.
2. When ordering a terminal guard, quote the appliance model number.
3. The flue terminal guard should be positioned centrally over the terminal and fixed as illustrated.
Fig. 19
8.9 Flue Deflector ( Fig. 18a )
1. Push the flue deflector over the terminal end. It may point upwards as shown, or up to 45° either way from vertical. Secure the deflector to the terminal
with screws provided.

9.0 Plume Displacement
9.1 Plume Displacement Kit (P.D.K.)
Kit No 5121371
Content of kit
1 70/110 Concentric Flue
1 1m 70 Dia Exhaust Flue Pipe
2 Support Brackets
1 93° Elbow/Plume Outlet Assembly
1 Flue Trim
2 "O" ​ Rings
1 Elbow 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).
