See Fig. 7.
8.1 The flue must be installed as specified in BS

8.2 The terminal must not cause an obstruction nor the
discharge cause a nuisance.
8.3 If the terminal is fitted within 1000 mm of a plastic or
painted gutter or within 500 mm of painted eaves then an
aluminium shield at least 1000 mm long should be fitted to
the underside of the gutter or painted surface.
8.4 If a terminal is fitted less than 2 metres above a
surface to which persons have access then a guard must
be fitted.
8.5 The terminal guard must be evenly spaced about the
flue terminal and fixed to the wall using plated screws.
8.6 In certain weather conditions a terminal may plume
when the appliance is operated. Siting where this could
cause a nuisance should be avoided.
8.7 Take care to ensure that combustion products do not
