When planning the installation, consider the location of the
vent terminal and clearances. Some of the most common
clearances to keep in mind are shown in Figure 11.
Important: All vent clearances must be maintained.
Check your vent termination clearances against Figures
11 and 12.
The vent should be placed so that people cannot be burned
by accidentally touching the vent surfaces when the stove
is operating.
The vent termination should be located where it cannot be
damaged by such things as automobile doors, lawn mowers
or snowblowers and it should be located away from areas
where it could become blocked by snow, etc.
Some considerations are:
• Obstructions or impediments to venting.
• Nearby combustible materials that could come into contact
with combustion exhaust gases.
• Other nearby openings {within 9” (230 mm)} through which
exhaust gas could reenter the building.
• All vegetation within 3’ (914 mm) that may interfere with
the draft.
Other factors that inuence where the installation will be
sited include the location of outside walls, where additional
heat may be desired in the home, where the family members
gather most regularly, and perhaps most importantly, the
distance limitations of the venting system.
Vent Termination Clearances
Your stove is approved to be vented either through the side
wall, or vertical through the roof.
• Vermont Castings Group does not require any opening
for inspection of vent pipe.
• Only venting components specically approved and
labelled for this stove may be used.
• Minimum clearances between vent pipes and
combustible materials is one (1”) inch (25mm), except
where stated otherwise.
• Venting terminals shall not be recessed into a wall or
siding.
• Horizontal venting must be installed on a level plane
without an inclining or declining slope.
There must not be any obstruction such as bushes, garden
sheds, fences, decks or utility buildings within 24” from the
front of the termination hood.
Do not locate termination hood where excessive snow or ice
build up may occur. Be sure to check vent termination area
after snow falls, and clear to prevent accidental blockage of
venting system. When using snow blowers, make sure snow
is not directed towards vent termination area.
Location of Vent Termination:
It is imperative the vent termination be located observing the
minimum clearances as shown in Figure 11.
• The horizontal termination must not be recessed into
the exterior wall or siding.
• Horizontal vent runs must be level toward the vent
termination.
• Clearances around the vent termination must be
maintained.

Venting System Assembly
General Information:
The Intrepid is approved for installation only with the Dura
Vent components listed on Page 14. Follow these and the
vent component instructions exactly.
For U.S. installations: The venting system must conform
with local codes and/or the current National Fuel Gas Code,
ANSI Z223.1/NFPA 54
For Canadian installations: The venting system must
conform to the current CSA B149.1 installation code.
Options:
The DuraVent Direct Vent Pro offers a complete line of
component parts for both horizontal and vertical installation.
Many items are offered in decorative black as well as
galvanized nish. The galvanized pipe and ttings may
be used for concealed locations such as attics, or spaces
where corrosion is a factor, such as above the rooine.
Decorative black painted sections are recommended for
use on visible interior runs. Decorative brass trim kits are
available for both Wall Thimbles and Ceiling Support Boxes.
Snorkel Terminations are available for applications which
may require vertical rise on the building exterior.
Planning Your Installation:
There are two basic types of Direct Vent Pro installations:
Horizontal Termination (Figs. 18 and 19)
Vertical Terminations (Figure 20)
When planning your installation, it will be necessary to select
the proper length of vent pipe for your particular requirement.
For horizontal installations, check these instructions to
determine the minimum clearance from the rear of the
appliance to the wall. It is also important to note the wall
thickness. Select the amount of vertical rise desired or
required, for “vertical-to-horizontal” installations (verify that
it is within the minimum and maximum limits. Refer to Page
7). To determine the length of vent pipe required for vertical
installations, measure the distance from the appliance ue
outlet to the ceiling, the ceiling thickness, the vertical rise in
an attic or second story, and allow for sufcient vent height
above the rooine. For multi-story applications, restops
are required at each oor/ceiling level. If an offset is needed
in the attic, additional pipe and elbows will be required.

Rear Vent:
Use components listed on Page 14 under ‘Basic Straight
through-the-Wall Installation’ for an installation where the
heater is parallel to the wall and the vent system extends
straight back through that wall.
1. Locate the vent opening on the wall. Refer to Figures 20
& 21 to determine the top of the opening centerline. It may
be necessary to rst position the stove and measure to
nd the hole location. Depending on whether the wall is
made of combustible materials, cut the opening to the size
shown in Figure 21. Combustible wall openings must be
framed as shown in Figure 21.
2. Measure the wall thickness and cut the zero clearance
sleeve sections to proper length (MAXIMUM 12”).
Assemble the sleeve with the #8 sheet metal screws
supplied. Attach the restop plate to the sleeve end with
the holes. (Figure 22) NOTE: The zero clearance sleeve
is required in combustible walls only.

4. Slip the wall cover over the interior end of the horizontal
pipe and install into the zero clearance sleeve. Seal the
joint inside the wall plate if needed to keep cold air from
being drawn into the home.
5. Install the vent terminal. (Figure 22) Guide the inner and
outer vent termination collars into the adjacent pipes.
Double check that the vent pipes overlap the collars by 2”.
Fasten the termination to the outside wall with the screws
provided, and caulk the joint with weatherproof sealant.
6. Use wall straps to support vertical pipe runs at 4’ (1219
mm) intervals.
Horizontal Installation
Step 1. Set the gas appliance in its desired location. Check
to determine if wall studs or roof rafters are in the way once
the venting system is attached. If this is the case, you may
want to adjust the location of the appliance.
Step 2. DirectVent Pro pipe and ttings are designed with
special twist-lock connections. To connect the venting
system to the appliance ue outlet, a twist-lock appliance
adaptor is built into the appliance at the factory. Assemble
the desired combinations of black pipe sections and elbows
to the appliance adapter with pipe seams oriented towards
the wall or oor, as much out of view as possible. (Figure
24)
St977

Figure 26
NOTES:
1. The horizontal run of venting must be level, or have a
1/4” (6 mm) rise for every 1’ (305 mm) of run toward
the termination. Never allow the vent to run downward.
A downward slope can trap heat and become a possible
re hazard.
Figure 25
2. Horizontal vent runs of vent pipe must be supported to
prevent any downward sags. Horizontal pipe sections
should be supported at least every 4’ (1.2 m). Wall straps
can be used for this purpose. Alternatively, plumbers
tape or other suitable noncombustible material can be
used to support the vent pipe.
3. DirectVent Pro venting requires no sealant.
Step 3. With the appliance adapter and pipe section
attached, slide the stove into its correct location. Mark
the wall for a square hole that measures 10” x 10” (254
x 254 mm). The centerline of the pipe should line up with
the center of the square hole. (Figure 26) Cut and frame
the square hole in the exterior wall where the vent will be
terminated. If the wall being penetrated is constructed of
noncombustible material only, i.e. masonry block, brick or
concrete only, a hole with zero clearance is acceptable.

into the female end until the locking lugs are covered.
Twist the female end clockwise an eighth of a turn to lock
sections together. (Figure 25) Screws are not required to
secure the joint, but are acceptable provided they do not
penetrate the inner wall of the vent pipe.

component must
be used between
the horizontal
termination cap and
the wall surface.
The vinyl siding
standoff prevents
excessive heat from
possibly melting
the vinyl siding material. Vinyl siding standoffs are not
required with snorkels. For vinyl wall installations a
4-piece vinyl siding standoff should be assembled and
installed between the horizontal termination cap and the
exterior wall. (Figure 30) The vinyl should be cut away to
the outer edges of the assembled standoff.

codes, and must not be easily blocked or obstructed.
Refer to Pages 10 and 11 for proper Termination Clear-
ances.
For installations requiring a vertical rise on the exterior of
the building, 14” (356 mm) and 36” (914 mm) tall snorkel
terminations are available. (Figure 27) Follow the same in-
stallation procedures as used for standard horizontal termi-
nations. If the snorkel termination must be installed below
grade level, (i.e. basement application), proper drainage
must be provided to prevent water from entering the snorkel
termination. (Figure 28) Do not attempt to enclose the snor-
kel within the wall or any other type of enclosure.

Vertical Installation
Step 1. Check these installation instructions for required
clearances (air spaces) to combustibles when passing
through ceilings, walls, roofs, enclosures, attic rafters or
other nearby combustible surfaces. Do not pack air spaces
with insulation. Check these instructions for maximum
vertical rise of the venting system and any maximum
horizontal offset limitations.
Step 2. Set the gas appliance in
the desire location. Drop a plumb
bob down from the ceiling to the
position of the appliance ue exit,
and mark the location where the
vent will penetrate the ceiling.
Drill a small hole at this point.
Next, drop a plumb bob from the
roof to the hole previously drilled
in the ceiling, and mark the spot
where the vent will penetrate the
roof. (Figure 33) Determine if
ceiling joists, roof rafters, framing
or other materials will obstruct
the venting system. You may
wish to relocate the appliance or
to offset, to avoid cutting load-
bearing members.
Step 3. To install the round
ceiling support/wall thimble cover
in a at ceiling, cut a 10” x 10”
(254 x 254 mm) square hole in
the ceiling (unless otherwise
specied) centered on the hole
drilled in Step 2. Frame the hole
as shown in Figure 34.
Step 4. If the twist-lock appliance adapter has not been
installed on the stove, do so now.
Step 5. Assemble the desired pipe sections and elbows
necessary to reach from the appliance adapter up through
the round ceiling cover or support box. Ensure that all pipe
and elbow connections are in their fully twist-locked position.

3. When penetrating through stucco wall, install the
counter ashing. The counter ashing allows stucco,
or other materials, to be nished directly to the sides of
the termination cap. First attach the counter ashing to
the base of the horizontal termination cap with the small
screws provided, then mount entire assembly onto the
wall with the four (4) 21⁄2" (64 mm) wood screws provided.
4. If the optional copper version of the horizontal termination
cap is installed, use an appropriate noncombustible
material to avoid direct contact between the galvanized
and copper metals to prevent possible galvanic reaction.
Step 5. Before connecting your horizontal pipe sections to
the horizontal termination cap, slide the wall thimble cover
over the pipe section nearest the interior side of wall. (Figure
31)
Step 6. Slide the appliance and vent assembly towards the
wall, carefully inserting the pipe section into the cap assembly.
It is important the pipe section extends into the back of the
termination cap with a minimum overlap of 11⁄4" (32 mm). Use
the two (2) sheet metal screws provided to secure the pipe
section to the back of the termination cap. The wall thimble
cover will cover the screw heads. (Figure 31)

Step 8. Continue to add pipe sections until the height of
the system (before adding the cap) meets the minimum
building codes requirements as described in Table 2, Figure
37. Note that for steep roof pitches, the vent height must be
increased. In high wind conditions, nearby trees, adjoining
rooines, steep pitched roofs and other similar factors
can result in poor draft, or down drafting. In these cases,
increasing the vent height or switching to the high wind
termination cap may help to solve the problem.
Step 9. Slip the storm collar over the pipe section, and push
it down to the top of the roof ashing. (Figure 38) Use non-
hardening sealant between the storm collar and the pipe
section

Step 7. Slip the roof ashing over the pipe section(s) pro-
truding through the roof. Use a non-hardening sealant be-
tween the roof ashing and the roong to prevent water
leakage. Secure the base of the roof ashing to the roof
with roong nails. Ensure the roong material overlaps the
top edge of the roof ashing. (Figure 38) Verify that you
have at least the minimum clearances to combustibles at
the rooine and in the attic.
NOTES:
1. If exact lengths or distances must be met between elbow
offsets or elsewhere, use the pipe extensions to adjust
onto standard pipe sections. (Figure 35)
2. If an offset is necessary in the attic to avoid obstructions,
it is important to support the vent pipe in order to avoid
excessive stress on the elbows. Wall straps or plumber
tape may be used for this purpose. (Figure 36)
3. Wherever possible, use 45° elbows instead of 90°
elbows. The 45° elbow offers less restriction to the ow
of ue gases and intake air.

Step 6. Cut a hole in
the roof centered on
the small drill hole
placed in the roof in
Step 2. The opening
should be of sufcient
size to meet the
minimum requirements
for clearance to
combustibles, as
specied. Continue
to assemble pipe
sections and elbows as
necessary to reach up
through the roof line.
Galvanized pipe and
elbows may be utilized
in the attic, as well as
above the rooine.
The galvanized nish
is desirable above the
rooine, due to higher
corrosion resistance.
