Correct Stretching Technique For
DuraFlex Aluminum Chimney Liner
Two people are needed to stretch the
aluminum flex.
Stretch half the length of the liner at a
time following this procedure:
•
Start by facing each other at the
mid-point in the liner.
•
Hold the liner firmly in hands. One
person walk backwards, stretching
portions of the liner as he or she is
backing-up.
•
It is important that as the liner is
stretched, the liner is allowed to
rotate naturally. This will help ensure
the liner can stretch to reach its
maximum length without damaging
the liner.
•
Repeat with the other half of the
liner, stretching as described above.
•
Do not over-stretch the liner beyond
its specified length. Doing so can
damage the liner.
•
The liner should now be at full length.
