Back
to DuraTech Pipe Systems
DuraTech is an all-fuel chimney system designed for
appliances that require a UL 103 or a UL HT chimney system,
such as wood stoves, fireplaces, furnaces, boilers, stoves,
ranges, water heaters, or other appliances fueled by wood,
oil, coal, or gas, and zero clearance fireplaces that are
factory-built. With a Thermal Tech blanket insulation encased
between dual walls, DuraTech offers the optimum in safety
and performance. Inner wall .020" 430 stainless steel. Outer
wall options of .016" 430 stainless steel or .021" galvalume
steel. A ceramic refractory blanket insulation is encased
between walls. Stainless steel end rings seal the pipe.
It keeps the outer wall of the chimney cool, while ensuring
high flue gas temperatures for optimum draft performance.
No locking bands or mechanical fasteners required. DuraTech's
sleek 1" wall design provides for easy installation, such
as 5"-8" diameter pipe installation through 16" on-center
rafters. A black finish is available in 6", 9", and 12"
pipe lengths. DuraTech carries a limited-lifetime warranty.

Typical Installations
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.
Firestop Radiation Shield must be used when a chimney
passes through a floor or ceiling without a support
box.
