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 largerhole may be required.
2- Make sure the DuraSeal Flex is supported at the bottom of the
chimney. Refer to
Figure 12
forguiding 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 25)
S- It is strongly recommended to use a drain between the Male Flex
Adapter and the appliance (refer to Condensate Drains section).
