APPLICATIONS
The DTC chimney has been designed for use with
wood, gas, oil, and coal in residential, commercial
and industrial applications, specially developed for
use with controlled-combustion stoves and wood
burning replace .
In the USA, DTC is listed to UL-103HT, 2100°F in
diameters of 5, 6, 7, 8 and 10 inches.
In Canada, DTC is listed to ULC-S629, 2100° F in
diameters 6, 7, and 8 inches for wood/coal application.
In Canada, DTC is also designed for use with gas or
oil red heating appliances such as furnaces, water
heaters, and other appliances, as per ULC-S604 in
diameter 5 to 10 inches.
If you are planning to install a wood stove, we rec-
ommend that you:
1. Choose the right size stove. Do not buy one larger
than you need.
2. Connect only one appliance to a chimney.
3. Never overre your stove. If any part of the stove or
stove pipe is glowing red, then you are overring.
Immediately close the stove’s dampers until the
system cools. The high temperature caused by
overring can permanently damage the stove and
stove pipe and may overheat nearby combustible
walls and furniture.
WOOD AND COAL STOVES
RECOMMENDATIONS
Clearance
The clearances stated in this guide are minimum re-
quirements: if more space is available, use it. Min-
imum clearances mean leaving unobstructed air
space. Do not ll these spaces with any material
whatsoever, especially not home insulating material
except specied otherwise. If you insulate your attic
later, be sure to maintain the necessary clearance.
Inspection
Contact local building or re ocials about restric-
tions, installation inspections and permits that may
be required in your area.
Replacement Parts
If a component of your chimney system is damaged
it must be replaced by an identical one from
DuraVent.
4. Install the stove and stove pipe as described in the
installation instructions accompanying the stove.
Be certain to maintain the required clearances to
combustible construction.
5. Keep your ue gases between 300°F and 500°F.
This will maximize eciency while minimizing con-
densation and creosote formation. Do not ll your
stove with wood and allow it to smolder for 8 to
10 hours. This condition produces large amounts
of creosote in the chimney.
6. Do not burn sea driftwood or treated wood. These
combustibles are highly corrosive to all types of
stainless steel.
FACTORY BUILT FIREPLACES
DTC is suitable for use with closed or opened re-
places certied for use with the DTC.
When doing so please refer to the replace installation
instruction to install the chimney.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
CREOSOTE - FORMATION AND NEED
FOR REMOVAL
NOTE: ALL DIMENSIONS ARE IN INCHES.
Wood stoves can quickly create large deposits of
creosote in the chimney. Some wood stoves can
create enough creosote in two weeks to cause a
chimney re.
When wood is burned slowly, it produces tar and other
organic vapours, which combine with expelled mois-
ture to form creosote. The creosote vapours condense
in the relatively cool chimney ue of a slow-burning
re. As a result, creosote residue accumulates on
the ue lining. When ignited this creosote makes an
extremely hot re.
When using a wood stove, we recommend that you::
1. Initially, inspect the chimney system weekly. You
will learn how often it will be necessary to clean
your chimney.
2. The chimney should be inspected at least once every
2 months during the heating season to determine
if a creosote or soot build-up has occurred: if a
signicant layer of creosote has accumulated (3
mm or 1/8’’), it should be removed to reduce the
risk of chimney re.
3. Have your chimney cleaned by a qualied chimney
sweep. If you want to clean your chimney yourself:
clean your chimney using plastic or stainless steel
brushes. Do not use a brush that will scratch the
stainless steel interior of your chimney.
4. Do not expect chemical chimney cleaners to keep
your chimney clean. Their use does not negate the
necessity of periodically inspecting and cleaning
your chimney.
CAP REMOVAL FOR MAINTENANCE
To remove cap, unscrew the collar screw to un-
tighten the collar.
Pull on the cap to remove it from the chimney.
To put the cap back in place, slide it over the
chimney and then tighten the collar using the col-
lar screw.

1. The chimney is intended for use with solid, liquid,
and gaseous fuel burning appliances. In Canada,
only 6”, 7” and 8” dia. for solid fuel.
Allowable ue gas temperature:
Maximum continuous 1200° F (650°C)
Brief forced ring 1400°F (760°C)
Tested to 2100°F (1150°C) - 30 minutes
2. The maximum height of chimney supported by the
various DuraVent supports are outlined on Table 1.
3. The supports described in this manual should only
be used with DuraVent’s model DTC, 5”, 6”, 7”, 8”
and 10” factory built chimneys.
4. Size the chimney in accordance with the appliance
manufacturer’s instructions.
5. When a restop is required, it is important to follow the
framing dimensions for oor openings as prescribed
in this manual. see Table 2).
6. A chimney servicing a replace or an incinerator shall
not serve any other appliance.
7. The chimney shall extend at least 3 ft above its point
of contact with the roof and at least 2ft higher than
any wall, roof or adjacent building within 10 ft of it.
8. The maximum height of an unguided chimney above
the roof is 5 ft. If the chimney extends more than 5 ft.
above the roof, a Universal Roof Brace (XRB) must
be used.
9. The clearance between single wall pipe and unpro-
tected combustible material must not be less than 18”
(see National Building Code and NFPA 211) except:
The distance between the vertical stove pipe and the
ceiling may be less than 18” and will be established
by the nish support.
10. Multi-Story: Consult local building codes for re-
quirements in your area. In the U.S., the National
Fire Protection Association Standard #211 states:
“Factory-built chimneys that pass through oors of
buildings requiring the protection of vertical openings
shall be enclosed with approved walls having a re
resistance rating of not less than one hour when
such chimneys are located in a building less than
4 stories in height, and not less than 2 hours when
such chimneys are located in a building more than 4
stories in height.” In Canada, except in single-family

WARNING
The clearance between the chimney and combustible
material must not be less than 2", except where
established by the support. Do not ll this area with
insulation unless directed otherwise in these
instructions.
GENERAL INSTALLATION NOTES (CONT’D)
1
and two-family dwellings, chimneys which extend
through another story must have an enclosure with a
re resistance rating equal to or greater than that of
the oor or roof assembly through which they pass.
11. Do not ll the 2” space around the chimney with
household insulation or any other material unless
specied otherwise. Insulation placed in this area
could cause adjacent combustibles to overheat.
12. Self-tapping stainless screws are not required, but
may be used to reinforce the connection and avoid
accidental unlocking of chimney lengths. Use only
1/2” self-tapping screws. Do not penetrate the inner
wall of the chimney.
13. When penetrating an exterior wall or ceiling/roof
assembly, the vapor barrier must be repaired. This
is easily accomplished by attaching the vapor barrier
to the outer perimeter of any wall thimble, Firestop,
or ceiling support component using approved
sealant or tape, while also maintaining the minimum
clearances-to-combustibles to the chimney’s outer
wall. When penetrating the building envelope, the
gap between the outer layer of chimney and any
Firestop or wall thimble can be sealed using high-
temperature rated (316°C / 600°F) silicone caulking.
Should you require further clarication, consult your
local authority having jurisdiction.
13. The safe operation of a factory-built chimney as-
sembly is based on the use of parts supplied by the
manufacturer and the performance of the assembly
may be aected if the combination of these parts is
not used in actual building construction.
Acceptance of the assembly is void if the installation
instructions are not followed.
15. Provisions must be made to ensure that all interior
portions of the chimney be accessible for inspection
and cleaning.

NOTE: The Reduced Clearance Support (RCS)
comes with a collar. It can be discard-
ed for a Cathedral Ceiling application, it
is not required.
Step 1: Locate the chimney in a conve-
nient location as near as possible
to the appliance outlet. Cut and
frame an opening in the roof for the
support (see Table 5). The sides of this hole
must be vertical (see Figure 11).
Step 2: From above, place the support in the open-
ing.
NOTE: The bottom portion of the support must ex-
tend below the ceiling. Distance will vary accord-
ing to pitch (see Table 6). The minimum horizontal
distance between the single wall stove pipe and
the vertical surface is 18”.
Step 3: Use a level to ensure the support is verti-
cal. If the support extends above the roof,
cut it ush with the top of the roof. Attach the
support to the framed opening using (12)-3”
spiral nails or #8 x 1 1/2” wood screws (see
Figure 10).
Step 4: Place rst chimney length into the support.
Twist to lock into place. Wrap the insulation
pad around the chimney section removing
any excess. Slide insulation pad into the
space between the chimney section and
support making sure the insulation makes
contact with the bottom of the support.
Additional pieces of insulation can be loosely
tucked down within corners. Do not com-
press insulation. This reduces eectiveness.
Where desired, an extension (SE) is avail-
able for the support. This may be needed
in steeper cathedral applications. Approved
insulation can be used within the extension.
It must be listed/compliant with ASTM E136/
ULC S114 as non-combustible, have a
melting temperature above 2000°F/1100°C,
and be water resistant with low moisture

instructions on page 11
(refer to Figure 13 for visual references).
Approved insulation can be used within
the extension and support surrounding
the chimney. It must be listed/compliant with
ASTM E136/ULC S114 as non-combustible, have
a melting temperature above 2000°F/1100°C, and
be water resistant with low moisture absorption.
Materials such as
rockwool qualify.
SUPPORT EXTENSION (CSE24)
(For Square Support only)
Steep pitched cathedral ceilings may
require the use of a Square Support
extension (CSE24). This piece ts
down inside the square support and can
be adjusted to increase the support's length by up
to 22"
The extension is attached to the support using
the eight metal screws provided. Be sure there is
at least a 2" overlap where the extension joins the
support.

OFFSET CHIMNEY
It may be necessary to oset the chimney to clear
an obstruction such as a joist or truss, or to position
the chimney close to the ridge cap. A maximum of
two osets (4 elbows in all) is allowed in a chimney.
The chimney must not be inclined more than 30° from
vertical or 45° (Canada Only).
The minimum chimney height when using 15° osets
is 10’.
The minimum chimney height when using 30° or 45°
osets is 15’.
The maximum length of unsupported oset chimney
is 6’. If the oset chimney is longer than 6’, then it
must be supported at 6’ intervals using an Oset
Support (RESU) or Wall Band (WSU).
INSTALLATION INSTRUCTIONS
Install the required support and the chimney as de-
scribed in the previous pages of installation instruc-
tions. When you reach the height at which the elbow
will be installed, proceed as follows:
Step 1. Install the insulated oset elbow on the vertical
chimney length. Turn it in the required direction
and fasten it to the chimney with the (4)-1/2’’
metal screws provided.
Step 2. Place the required oset chimney length (see
Table 7 below) on the elbow. Turn it clockwise
to lock it in place.
Step 3. Use another elbow to turn the chimney ver-
tically. Again secure the elbow to the chimney
length using the (4)-1/2’’ metal screws.
WARNING
A support must always be installed right above each
offset (two elbows) to support the chimney above the
offset.

EXTERIOR INSTALLATION
ROOF SUPPORT (RS)
The Roof Support has three possible uses:
It may be used to support a chimney from the
roof. It adjusts to any roof pitch.
It may be used on a oor, ceiling or roof above
an oset to support the chimney above the
oset.
It may be used on a oor, ceiling or roof as
a supplementary support when the chimney
height exceeds that of the primary support.
(See maximum length height supported,
page 3).
INSTALLATION INSTRUCTIONS
With the chimney extending through the opening in
the roof, ceiling or oor proceed as follows (Refer
to Figure 17 for visual references):
Step 1. (USA ONLY)Install the roof radiation shields
in the roof joists. These shields consist of four
metal plates. Nail one plate to each side of the
joist using (2) 2-1/2” nails.
Step 2. Assemble the Roof Support’s Collar to t
your chimney diameter. Continue to assemble
the support as described in the instructions
supplied with the support.
Step 3. Slip the assembled Roof Support down over
the stainless steel chimney until its brackets
rest on the roof or oor. Tighten the collar
around the chimney, (see Figure 16).
Step 4. Center the chimney and nail or screw the
support to the roof or oor using (8) - 2-1/2"
nails or (8)
Nº. 8 - 1-1/4" wood screws. (Fig-
ure 16).
Step 5. Install the remaining chimney lengths, until
the required chimney height is reached.

Step 6. ROOF FLASHING INSTALLATION
Put the roof ashing in place. Seal the joint
between the roof and the ashing with roong
compound.
For sloping roofs, place the ashing under the
upper shingles and on top of the lower shingles.
Nail the ashing to the roof using nails. Place
the storm collar around the chimney and slide
down on top of the ashing. Tighten it with the
bolt supplied making sure the joint is properly
caulked (see Figure 9).
Step 7. Refer to page 3 for Cap installation.

16 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
INSTALLATION NOTES
1. The chimney may be enclosed or unenclosed.
2. Maintain 2" clearance to combustible materials.
Do not ll the 2" space around the chimney with
insulation or any other material.
3. A Wall Strap or Re-Support must be used to
secure the chimney to the wall when used on an
exterior wall. Maximum distance between wall
bands is 8’.
4. The horizontal chimney length passing through the
wall must project a minimum of 5” and no more
than 24” beyond the inside wall. Minimum projection
is required to ensure appropriate clearances are
maintained once stovepipe is installed.
5. If an exterior installation is to be enclosed, allow
for access to base of tee to facilitate required
cleaning.
6. The minimum distance between the bottom of the
Tee or Support and any horizontal combustible is
2” by using an insulated tee cap (TCI).
RE-SUPPORT
When a chimney is used along a wall,
this support may be used to support
the chimney. The height of chimney
supported is shown in supported
height See Table 1.
INSTALLATION INSTRUCTIONS
Install the support as follows (see
Figure 18):
Step 1. Assemble the collar to t your chimney
diameter. Continue to assemble the support
as described in the instructions supplied
with the support.
Step 2. Slip the support down over the chimney
to the proper location.
Step 3. Tighten the collar around the chimney.
Step 4. Attach the support brackets to the wall
using (8) 3" nails or (8) Nº. 10 x 1-1/4" wood
screws.
NOTE: Be sure that the support attaches to a framing
and not merely to dry wall or siding.
Step 5. Continue installing the chimney.

This chimney will provide optimum performance
when installed within the heated space of a build-
ing. The consequences of installing the chimney
outdoors, up the exterior wall of a building could
result in:
-Back-drafting during cold weather when the
connected appliance is not operating
-Weak, unstable draft
-Increased creosote accumulation
-Increased potential for condensation of water
vapor in the chimney ue
-Decreased eciency of the connected appliance
If you do install an exterior chimney, we recommend
that you enclose it using an insulated enclosure.

INSTALLATION INSTRUCTIONS
Step 1. Determine where the chimney will pass
through the wall.
• For concrete walls cut an opening slightly larger
than the chimney.
• For combustible walls cut and frame a hole 4"
larger than the chimney, midway between the wall
studs (see Table 8 below for sizing).
Normally wall studs are placed at 16" on center.
With the hole midway between them, the support
will fasten to these studs and thus ensure a strong
attachment to the wall (see Figure 20).
Step 2. Wood walls: Place the exterior half of the Wall
Thimble (WTI) in the opening from the outside.
Nail in place using (4) 2’’ nails or 1’’ screws.
This Wall Thimble is adjustable from 7’’ to 12’’
(see Figure 21). Make sure the insulation pad
is cut to the desired length according to the
wall thickness. Place the interior half of the
Wall Thimble inside the exterior half of the Wall
Thimble. For a wall requiring more than 12”, a
shield extension can be eld fabricated using
galvanized sheet metal 26 gauge minimum.
Ensure the opening for the chimney to pass through
is straight and level. Screw the outer thimble in place
with the provided screws (see Figure 22).
NOTE: The cavity surrounding the wall thimble metal
shield can be lled with insulation (see Figure 22).

EXTERIOR INSTALLATION (CONT’D)
Step 3. The minimum length of insulated chimney
required to pass through the wall will be
thickness plus 7”. The insulated chimney
must extend at least 5” into the room beyond
the nished wall. Insert this chimney length
in the side branch of the insulated tee. Turn it
clockwise to lock it in place. Seal this joint by
wrapping it with the aluminum tape supplied
with the tee. Mount the insulated tee on the
support so that the chimney length which will
go through the wall is perpendicular to the
side of the support that will fasten to the wall.
NOTE: The supports (RESU or TSA) can be installed
above the Tee. (See Figure 24A).
Step 4. This step will require 2 people: (see Figure
23). Insert the chimney length of this tee-sup-
port assembly into the hole in the wall. Using a
level, ensure the tee is vertical, then attach the
support to the wall using (8) Nº. 10 x 1 - 1/4"
wood screws or 4" spiral nails.
NOTE: To provide sucient strength, the nails must
be driven into the wall studs. For concrete
walls, the support should be attached using
(8) 1/4” x 2” lag bolts.
Step 5. Attach the clean-out cap to the Tee Support
or Tee.
Step 6. Attach the ue extension to the horizontal
chimney length.
Step 7. Stack a chimney length on top of the Tee.
Turn it clockwise to lock it in place. Continue
until the required chimney height is reached.
NOTE: At 8' intervals, attach the chimney to the wall
using a Wall Strap or Re-Support.
Step 8. If the chimney passes through the roof, cut
a hole large enough to provide 2" clearance
between the chimney and the roof. For pitched
roof, see chart on page 4.
(FOR US Installs ONLY)
Install the Roof Radiation Shield in the roof joist.
