When shortening terminals
or terminal extensions, the
outer section only should be
cut first. This will allow access
to the inner section, which,
for a correct fit into the next
concentric pipe fitting, must
be cut so that it is 10 cm
longer than the outer section.

B23 open flue header vertical
terminal with air inlet filter
and 90° ellbow.
Note...On two, three and four boiler
arrangements, standard length vertical
terminals are supplied for each boiler.
These must be cut to length to maintain
the recommended 3° fall in the
main horizontal header, falling away
from the main flue riser.
The first terminal (for the boiler nearest
to the main flue riser) does not need
to be cut, but each terminal thereafter
should be cut 29mm shorter than the
previous terminal to achieve the
recommended 3° fall.
