DuraPlus is designed to stay cool on the outside, to provide a hot
draft on the inside, to boost stove efficiency, and to provide for a
fire-safe design that protects both the chimney and the building.
This triple-wall chimney features two insulating layers (ceramic
blanket, plus air space). The ceramic blanket insulation is held
securely in position, eliminating hot spots common with loose-fill
type insulations. In the event of a creosote fire, the compressible
blanket insulation permits the chimney liner to expand outwardly
in a radial direction.
Designed for normal, continuous operation at 1000° F flue gas
temperatures, DuraPlus is subjected to rigorous and stringent HT
requirements of the UL standard, including one hour at 1400° F,
plus three ten minute chimney fire tests at 2100° F.

• Refer to our Typical Venting Installation drawings to select the appropriate component
parts for your installation.
• A DVL/DuraBlack Chimney Adapter or DuraBlack Slip Connector must be used when
connecting DVL or DuraBlack stovepipe to A Ceiling Support or Wall Thimble. A Snap-Lock
Adapter must be used when attaching snap-lock stovepipe to DuraPlus.
• A Wall Thimble must be installed with an appropriate section of chimney pipe for all
horizontal through-the-wall installations. To accommodate thicker walls a wall thimble
extension can be field fabricated.
• An Attic Insulation Shield must be used in all installations that pass through an attic,
regardless of whether the attic is insulated or not. If chimney is enclosed in a chase in the
attic space, an Attic Insulation Shield is not required.
• A Firestop Radiation Shield must be used when a chimney passes through a floor
or ceiling without a Ceiling Support Box.

The following recommendations are a general guideline to
assist in the layout and selection of the chimney components
needed for your installation. Always follow DuraVent Installation
instructions before installing your chimney system(enclosed with
the cap or support box). Installation instructions can be viewed
online at www.duravent.com, under catalogs and instructions.
• The diameter of the chimney should match the outlet size of
the appliance. An improperly sized chimney results in poor draft
and excessive creosote formation.
• Measure the diameter of the appliance flue outlet. Select the
chimney and either DVL or DuraBlack connector stovepipe with
the same size diameter as the appliance flue outlet. For fireplace
installations, refer to the sizing chart in the back of the DuraTech
section of this catalog.
• Determine if the installation is a through-the-roof installation or
a through-the-wall installation. A through-the-wall installation
will require additional components (Wall Thimble, Tee w/ Cap,
Tee Support, and Wall Straps).
• Install the chimney in the interior of the structure whenever
possible. A cold exterior chimney will produce less draft and will
generate more creosote.
• If possible, avoid offsets that serve to restrict the natural draft.
A straight vertical installation is more efficient and less likely to
develop creosote. If an offset is required to avoid rafters or other
obstructions, measure the horizontal distance required and the
vertical height available. Both 15° and 30° elbows are available.
Elbows greater than 30° are not allowed in the United States. A
maximum of two offsets in a single installation are permitted.
Refer to the offset table in the back of this catalog. At least one
Elbow Strap is required for each offset. Elbow Straps ensure
adequate support.
• Determine the minimum chimney height above the roof
line. Building codes require a minimum of 3’ above the roof
penetration and at least 2’ higher than any portion of a building
within 10’. See figure 1. The termination cap is installed above
that point. If chimney is more than 4’ above the roof penetration
an Extended Roof Bracket is required.
• Measure the roof pitch. For example, a 6/12 pitch has a vertical
rise of 6” over a horizontal distance of 12”. Select the
appropriate flashing.
• Determine the total length of chimney and stovepipe required
for the installation. To calculate the installed per length of
6”-8” DuraPlus chimney pipe, subtract 1 1⁄2” per joint. Subtract
1 1⁄4” per joint of DuraBlack stovepipe. Subtract 1 1⁄2” per joint
of DVL stovepipe. Minimum chimney height, at sea level of
straight vertical chimney is 10’ to 15’ above the appliance outlet.
Higher elevations, or the use of elbows or a tee, will require
approximately 30% to 60% more height to provide for an
adequate draft.
• Be fire safe. Maintain at least 2” clearance to combustibles.
Follow local building codes and have your chimney inspected by
a certified professional.
