Refer to our Typical Installation drawings to select the appropriate component parts for your instal-
lation.
• DVL/DuraBlack Chimney Adapter must be used when connecting DVL pipe to a Ceiling Support
Box or Finishing Collar. When connecting DuraBlack pipe, a DVL/DuraBlack Chimney Adapter,
DuraBlack Slip Connector, or Snap-Lock Adapter must be used.
• Wall Thimble must be installed with an appropriate length of chimney pipe for all horizontal
through-the-wall installations. To accommodate thicker walls, the telescoping pieces of the Wall
Thimble can be separated, and a field-fabricated extension may be installed.
• Attic Insulation Shield must be used in all installations that pass through an attic, regardless of
whether the attic is insulated or not.
• Firestop Radiation Shield must be used when a chimney passes through a floor or ceiling without
a support box.
