FLUE SYSTEM
The provision for satisfactory flue termination must be made in accordance with BS
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
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.
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:
