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 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.

The inner pipe diameter should match the outlet size of the appliance. For installations that require 4″ vent and the appliance has a 3″ outlet, use an Increaser Adapter 3″-4″.
Check the appliance manufacturer’s Installation Instructions to confirm which types of vent configurations are permitted (i.e. horizontal, vertical, chimney reline, etc.). Also, check for any venting restrictions such as maximum horizontal run, minimum and maximum vertical rise, maximum offset, etc.
Be fire-safe! Maintain the minimum clearances (air-space) between the vent pipe and nearby combustibles, as specified in the appliance manufacturer’s installation instructions. Use proper support and bracing. Follow local building codes and have your venting system inspected.
