Be careful when passing through the damper
not to damage the flex liner. One person
should feed the liner through the chimney,
and another person should pull the liner
from the bottom, using the rope to guide the
liner through to the chimney bottom. Note: If
additional lengths of Flex Liner are needed to
span the chimney height, use a Flex Coupler
to connect the pieces of Flex Liner together.
Connect the flex to the coupler by using four
sheet metal screws for each side (see Figure
3). Apply high temperature sealant on the
exhaust side.
5. After carefully feeding the Flex Liner down
the chimney to the bottom, form an angle to
line up the Flex Liner with the vent opening
on the appliance. Important: Do not let the
Flex Liner sag below the level at which it will
connect to the appliance or connector. This
could allow hot gas to become trapped and
potentially become a fire hazard. The Flex
Liner path should always be sloped up toward
the Co-Linear Cap.

6. Remove the Flex Pull-Down from the Flex
Liner and temporarily secure the Flex Liner
at the top of the chimney. Be sure to leave
2-3 inches of flex above the existing chimney
to allow for connection to the Co-Linear Cap
(see Figure 5).
7. Repeat the above steps for the second
length of flex.
