BASIC DURASEAL FLEX LINER INSTALLATION
1- Determine the required location and opening in the masonry chimney. For a
basic DuraSeal Flex installation the opening must be large enough for the mortar
sleeve and Male Flex Adapter and the DuraSeal Flex to easily pass through. If a
Tee application is necessary, a larger hole may be required.
2- Make sure the DuraSeal Flex is supported at the bottom of the chimney. Refer to
Figure 10 for guiding and support installation in the masonry chimney.
3- The DuraSeal Flex liner must be installed from the top of the masonry chimney.
To prevent damage, one person should feed the liner through the chimney and
another person should pull the liner from the bottom. To ease the installation, you
can attach a rope to the DuraSeal Flex liner above the Male Flex Adapter. Doing
this will reduce the chance of breaking the seal between the DuraSeal Flex and
the Male Flex Adapter.
4- The DuraSeal Flex must stay within the masonry chimney; however the Elbow or
other DuraSeal components will extend beyond the masonry chimney. (Figure
16)
5- It is strongly recommended to use a drain between the Male Flex Adapter and the
appliance (refer to Condensate Drains section).

MAINTENANCE INSTRUCTIONS

As with all vents, the DuraSeal vent system should be inspected at least annually for
the presence of deposits or debris and any accumulation should be removed. The vent
system should also be inspected at regular periods for signs of leakage of condensate
or combustion products at any joints.
If the vent system incorporates a drain hose from either a Drain length or a Drain tee
cap, the hose must be inspected periodically to ensure that water is in the trap loop.
If a proper trap loop is not maintained, exhaust from the connected appliances may
accumulate in the building area.
