There must be no leakage of smoke through the structure of
the chimney during or after the smoke pellet test and it is
important to check inside upstairs rooms adjacent to the chimney /
flue. Check the chimney pot / terminal and general condition of the
brickwork or masonry. If the chimney or flue is in poor condition or if
there is no up-draught do not proceed with the installation. If there is a
history of down-draught conditions with the chimney / flue, a tested and
certificated flue terminal or cowl suitable for the relevant flue type should
be considered.

leakage. See below in fig.1
