2-3-1 FLUE
The provision for satisfactory flue termination must be installed in accordance with local regulations.
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 discoloration that might occur on buildings in the vicinity,
it must also be located in a place not likely to cause nuisance. In cold or humidity weather water vapor may condense
on leaving the flue terminal The effect of such “steaming” must be considered. If the terminal is less than 1 meter
above a balcony, above ground or above a flat roof to which people has 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. X.
