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 Termination Kit
(Baseplate and Adaptor). (Figure 4)
Step 5. Repeat Steps 1-4 for the second
length of Flex Liner.
Step 6. At the top of the chimney, slide the
Baseplate over the two ends of the Flex Liner
and secure it to the surrounding masonry
using masonry anchor bolts. Before installing
the Baseplate, run a bead of non-hardening
sealant between the Baseplate and the
masonry to prevent moisture from entering the
chimney. (Figure 5)
Note: Verify that there is sufficient room to
mount the Baseplate on to the masonry. You
must have a level surface in order to install the
Baseplate properly.
Step 7. Attach the Flex Liner ends at the top
of the chimney to the Co-Linear to Co-Axial
Adaptor. Use four sheet metal screws to
connect each Flex Liner run to the Adaptor.
(Figure 6) Mount the Adaptor to the Baseplate
using sheet metal screws as shown. (Figure 7)
Step 8. Twist lock the Vertical Termination
Cap (Standard or High Wind) to the Adaptor.
(Figure 8) Note: If you are planning to extend
the height of the chimney using DirectVent Pro
Pipe, please refer to the Direct Vent Installation
Instructions for information concerning the
proper procedure and restrictions of Direct
Vent Pipe. Also, consult the appliance
manufacturer for any height restrictions on the
chimney.
Step 9. Depending upon the type of
connection that your appliance has, it will
require either the Co-Linear Flex Connectors
or a Co-Axial to Co-Linear Appliance
Connector in order to attach the Flex Liners to
the appliance. For the Co-Linear connection,
attach the Co-Linear Flex Connectors to the
two outlets on the back of the appliance. See
the appliance manufacturer’s instructions for
details. Connect the two Flex Liner runs to
the Connectors using four sheet metal screws
each. For the Co-Axial connection, twist lock
the Co-Axial to Co-Linear Appliance Connector
to the adaptor on the appliance. Attach the
