The provision for satisfactory flue termination must be made
as described in BS 5440-1.
The appliance must be installed so that the flue terminal is
exposed to outdoor 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, it must also be located in a place not likely to cause
nuisance.
In cold or humid weather water vapour may condense on
leaving the flue terminal.
The effect of such “steaming” must be considered.
If the terminal is 2.1 metres above a balcony, above ground
or above a flat roof to which people have access, then a
suitable stainless steel terminal guard must be fitted.
The minimum acceptable spacing from the terminal to
obstructions and ventilation openings are specified in Fig.
