All-fuel, triple-wall
chimney system.
UL 103 HT.
The chimney system allows your stove or replace
to exhaust ue gases while a draft creates the draw
that pulls fresh combustion air into the stove. A well
balanced system provides an even, hot re when it
has good draft. The draft suction keeps smoke from
coming into the room. Insulation in the chimney pipe is
important because it helps keep the exhaust hot until
it is expelled outside. Heat in the chimney makes draft,
which pulls in more combustion air. This creates a hotter
re, delivering more heat to the chimney and resulting
in more draft. The size of the ue is important for the
system to work eciently. The appliance manufacturers
installation instructions will indicate how to size the ue
to match the stoves ue collar.
Stovepipe connects to the stove. It is the usually black
interior pipe that transitions from the stove to the
chimney pipe with an adapter. It is not insulated and
cannot penetrate ceilings or walls. Chimney pipe is an
insulated pipe that is rated to pass through walls and
ceilings. In addition to the chimney pipe, supports to
hold the system in place and shields to protect
areas from combusting are needed for the system. The
ashing, storm collar and chimney cap are required to
seal the system from moisture penetration.

Step 1.
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.
Step 2.
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.
Step 3.
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.
Step 4.
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. Please note that 45° elbows
are not allowed in the United States. At least one Elbow Strap is
required for each offset. Elbow Straps ensure adequate support.
Step 5.
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 ⁄” per joint. Subtract 1 ⁄” per
joint of DuraBlack stovepipe. Subtract 1 ⁄” 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.

• 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 eld 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 oor or
ceiling without a Ceiling Support Box.
