Using the Typical Venting Installation drawings,
select the appropriate component parts for your
installation.
DVL/DuraBlack Chimney Adapter must be used when
connecting DVL pipe to a ceiling support box or
finishing collar. When connecting DuraBlack pipe,
a 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 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 the attic
insulation.
