or a suitable alternative that will provide
satisfactory weatherproofing. The interior and
exterior trim can now be fitted.
4.5.1.1 EXTENDING THE FLUE
Connect the bend – supplied with the terminal kit
– to the top of the boiler using the boiler top
adapter and clamp (supplied, fig. 7). The additional
bends & extensions have push-fit connections,
care should be taken to ensure that the correct
seal is made when assembling the flue system.
Connect the required number of flue extensions
or bends (up to the maximum equivalent flue
length) to the flue terminal (fig. 7 & 7B).

4.5.2 CONCENTRIC VERTICAL FLUE
The vertical flue terminal can be connected directly
to the appliance flue outlet. Alternatively, an
extension or bend can be connected to the
appliance flue outlet if desired (see section 2.9),
however if additional bends are fitted, a reduction
must be made to the maximum flue length (see
table below).
