In certain weather conditions condensation may also accumulate on the outside of the
air inlet pipe. Such conditions must be considered and where necessary insulation of
the inlet pipe may be required.
In cold and/or humid weather water vapour may condense on leaving the flue terminal.
The effect of such ‘pluming’ must be considered.
The terminal must not be located in a place where it is likely to cause a nuisance.
For protection of combustibles, refer to IS 813 section 9.10.1. where the terminal is less
than 2m ( 6.6ft ) above a pavement or platform to which people have access ( including )
any balcony or flat roof. The terminal must be protected by a guard of durable material.
A suitable guard is available from the country distributor.
Where a terminal is fitted below a window which is hinged at the top, and where
the hinge axis is horizontal, and the window opens outwards, the terminal shall
be 1m below the bottom of the window opening.
If the boiler is to be located under stairs, a smoke alarm meeting the
requirements of I.S. 409 or equivalent must be fitted.
The flue must be terminated in a place not likely to cause a nuisance.
