NOTE: Before installing accessories, lubricate the internal
part of gaskets with silicon-based products. Avoid using
oils and greases.
– If the terminal discharges into a pathway or passageway check that
combustion products will not cause nuisance and that the terminal will
not obstruct the passageway.
– Where the lowest part of the terminal is fitted less than 2 m (78 in)
above ground, above a balcony or above a flat roof to which people have
access, the terminal MUST be protected by a purpose designed guard.
Terminal guards are available from Quinnell, Barrett, and Quinnell, Old
Kent Road, London. State model C2, (G.C. Part No 382946).
– Where the terminal is fitted within 850 mm (34 in) of a plastic or paint-
ed gutter, or 450 mm (18 in) of painted eaves, an aluminium shield at
least 1,500 mm (59 in) long must be fitted to the underside of the paint-
ed surface.
– The air inlet/outlet flue duct MUST NOT be closer than 25 mm (1 in) to
combustible material.
– In certain weather conditions the terminal may emit a plume of steam.
This is normal but positions where this would cause a nuisance should
be avoided.
