The provision for satisfactory flue termination must be
made in GB this must be in accordance with BS 5440-1,
for IE recommendations are given in the current edition of
I.S.813.
The appliance must be installed so that the flue terminal is
exposed to outside air.
The terminal must not discharge into another room or
space such as an outhouse or lean-to.
It is important that the position of the terminal allows a
free passage of air across it at all times.
The terminal should be located with due regard for the
damage or discolouration that might occur on buildings in
the vicinity and consideration must be given to adjacent
boundaries.
In cold or humid weather water vapour may condense on
leaving the flue terminal. The effect of such “pluming”
must be considered.
If the terminal is less than 2 metres above a balcony,
above ground or above a flat roof to which people have
access, then a suitable terminal guard must be fitted.
When ordering a terminal guard, quote the appliance
model number.
A suitable terminal guard is available from:
