DuraLiner Product Catalog
Planning Your Installation
1 Refer to the Typical Installations for the needed parts for installation.
2 The size of the liner should match the outlet size on the appliance.
3 Determine use of round or oval pipe based on the interior shape of the chimney.
4
Determine the length of liner needed. Subtract 1 ⁄” overlap per joint on pipe. When using
Extend-A-Cap Kit, liner must extend 6” above top of the masonry surface.
5
Make sure the top of the masonry chimney has a leveled surface to insure a proper fit for
the Extend-A-Cap or Transition Anchor Plate and to provide a secure, leak-proof installation.
6
If a free-standing appliance is used, select the vent or stovepipe pieces to connect from the
appliance to the liner. Refer to installation instructions.
7
For Installations using a Transition Anchor Plate, refer to the DuraTech, DuraPlus, or DuraPlus
HTC catalog section or installation instructions for proper parts and installation.
8
Important! Check to be sure the installation complies with all local and national code
requirements, including clearance to combustibles. Contact the local building inspector for
permit requirements.

ecient, and economical listed chimney system (DuraPlus HTC is
listed for use in Canada). See Typical Installations for details.
