guidance on this aspect.
A compartment used to enclose the appliance must be designed specifically for this purpose. This
appliance is not suitable for external installation.
5.3
Flue system
The provision for satisfactory flue termination must be made as described in BS 5440 part 1.
For Ireland (IE), refer to I.S.813.2002.
The appliance must be installed so that the flue terminal is exposed to external air.
It must not be installed so that the terminal discharges into another room or space as an outhouse
or lean-to. It is important that the position of the terminal allows a free passage of air across at
all times.
The terminal should be located with due regard for the damage or discoloration that might occur
to building products in the vicinity.
In cold and/or humid weather water vapour may condense on leaving the flue terminal; the effect
of such "steaming" must be considered.
Pluming may easily occur at the terminal. Where possible, terminal position which could cause a
nuisance should be avoided.
The minimum acceptable spacing from the terminal to obstructions and ventilation openings are
specified in Fig. 5.1.
