3.9.2 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.
