15. For aesthetic purposes it is permissible to route the 60Ø exhaust in an enclosed box, but the air inlet and plume outlet MUST
remain in free air.
16. It is also possible to separate the plume outlet from the 93° elbow to allow the flue to be installed as shown in Fig. 25.
17. To do this, first slacken the two screws retaining the plume outlet to the elbow, and remove the outlet (Fig. 26). The elbow can now
be used to connect the vertical to horizontal 60Ø exhaust (Fig. 25). Retighten the screws in the elbow.
18. The outlet can now be fitted into the female end of an 60Ø extension piece. It must be secured using two of the screws supplied in
the bag with the 'Jubilee' clip.
19. Mark the female end of the extension at 30mm as shown in two positions, directly opposite each other (Fig. 27).
20. Using a suitable bit (e.g. 2mm), drill through the extension and outlet. Secure using two of the screws supplied.
21. The remaining screw must be used to secure the adaptor to the concentric terminal.
22. When the plume outlet is positioned under a balcony or other projection (Fig. 28) it must protrude at least 200mm (it is not
necessary to extend it further than this).
23. When under balconies or projections it is permissible to rotate the concentric flue length up to 70°, clockwise or anti­clockwise (Fig.
29), if there is insufficient space to connect vertically.
24. This will allow the connection of the exhaust to the outlet spigot.
25. All other minimum & maximum dimensions must be adhered to, and the air inlet positioned such that it will not be subject to rain
entry.
