9.3 General Fitting Notes - P.D.K. (cont.)
16. For aesthetic purposes it is permissible to route the
70Ø exhaust in an enclosed box, but the air inlet and
plume outlet MUST remain in free air.
17. It is also possible to separate the plume outlet from
the 93° elbow to allow the flue to be installed as shown
in Fig. H.
18. When the plume outlet is positioned under a balcony
or other projection (Figs. I & J) it must protrude at least
200mm (it is not necessary to extend it further than this).
