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. 7f.
17. To do this, first slacken the two screws
retaining the plume outlet to the elbow, and
remove the outlet (Fig. 7g). The elbow can now
be used to connect the vertical to horizontal
60Ø exhaust (Fig. 7f). 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. 7h).
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. 7j) 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. 7k),
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 subjetc to rain entry.
