• Connect the ‘pull-in tool’ to the end of the
fl exible pipe, to enable insertion by pulling down
the chimney. See installation detail 2, page 9.
• When necessary, it is possible to extend the
fl exible pipe by joining additional lengths using
couplings. See installation detail 3, page 9.
• An inspection piece can also be added.
• A centralising bracing bracket needs to be fi tted
to the fl exible pipe at 2 meter spacing.
• Arrange brackets inverted on fl exible pipe so
as to ease passage down chimney and fi x each
bracket with a cable tie.
• At any point where the chimney is staggered,
fi t one bracing bracket before and one after the
step.
• Insert the pipe with the necessary bracing
brackets into the chimney.
• Do not grate the fl exible pipe on sharp edges.
• When the outside temperature is below 5° C
the fl exible pipe needs to be warmed up before
installation.
• Feed the rope down chimney and then whilst
feeding in the fl ex from the top, carefully pull
down the fl exible pipe from the bottom chimney
opening. Make sure that suffi cient space remains
between the fl exible pipe and the support plate in
order to allow fi tting of the bottom chimney bend.
Also ensure to leave a min of 200 mm of fl ex pipe
protruding at the chimney top.
• Detach the pull-in tool, once again exposing the
corrugated fl ex pipe end.
