INSTALLATION

Connecting the Flue

Flue System
The provision for satisfactory flue termination must be made as de-
scribed 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 less than 2 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. 1.
