INSTALLATION
/ 20
Connecting the Flue
Flue System
The provision for satisfactory ue termination must be made as described in BS 5440-1:2008.
The appliance must be installed so that the ue 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 ue 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 at roof to which people have access, then a suitable
stainless steel terminal guard must be tted.
The minimum acceptable spacing from the terminal to obstructions and ventilation openings are specied in Fig. 1.
