9.3 General Fitting Notes (cont.)
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
anti-clockwise (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.
