filled by carefully pouring water into the exhaust
section of the flue connection.
6.12.1 Flue Terminal Positions
Terminal position Minimum spacing
– If the terminal discharges into a pathway or passageway
check that combustion products will not cause nuisance
andthat 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.
– The air inlet/outlet flue duct MUST NOT be closer than 10
mm (0.4 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.

(*) This dimension to be used with ventilated soffits. With unvented
soffits this can be reduced to 75 mm and further reduced to 25
mm when a flue shield is used to protect from the effects of heat
and condensation.
(**) This can be reduced to 25 mm but it may be necessary to protect
the surfaces from the effects of heat and condensation.
