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.
