Liner as shown in the Basic Installation section.
Step 2. Begin to slide the appropriate Insulation Sleeve
(single-ply or double-ply, depending on your masonry
chimney) over the Flex Liner. If you liner will be going
through a Mortar Sleeve, leave that portion of the Liner
uncovered by the sleeve. Secure the Insulation Sleeve
in place with an Insulation Clamp at one end.
Step 3. Continue adding Insulation Sleeves along the
length of the Flex Liner, being sure that the previous
Sleeve overlaps the next Sleeve. Secure the overlap
with an Insulation Clamp (Figures 20, 21).
Step 4. Once you have the length of Liner insulated,
continue with Step 4 of the Basic Installation.
FLEX EXTENSIONS
For taller chimney installations where more than one
length of Flex Liner is required, additional lengths of
Flex Liner may be purchased in 5-foot or 35-foot
lengths. Two lengths of flex may be connected
together using the Flex Connector (Figure 22). It is
very important that the Flex Connector be installed
in the proper direction with the Flow arrow pointing
