discolouration that might occur on buildings in the vicinity, it must
also be located in a place not likely to cause nuisance.
In cold or humid weather water vapour may condense on leaving the
ue terminal.

If the terminal is less than 2 metres above a balcony, above ground or
above a at roof to which people have access, then a suitable stainless
steel terminal guard must be tted.
The minimum acceptable spacing from the terminal to obstructions
and ventilation openings are speci ed in Fig. 1.

by at least 300mm. Where any 1 vertical outlet is more than 300mm
above the other, then they shall be separated by at least 1500mm.
