system could result in serious injury,
property damage or loss of life.
INSTALLATION PRECAUTIONS
Consult local building codes before beginning the
installation. The installer must make sure to select the
proper vent system for installation. The approved 5 x 8
venting components are Duravent and Selkirk products
listed on Page 49. UL1777 flexible venting is also
approved for use on these models. Before installing vent
kit, the installer must read this replace manual and vent
kit instructions.
Only a qualied installer/service person should install venting system. The installer must follow these safety rules:
• Wear gloves and safety glasses for protection.
• Use extreme caution when using ladders or when
on rooftops.
• Be aware of electrical wiring locations in walls and
ceilings.
The following actions will void the warranty on your venting
system:
• Installation of any damaged venting component.
• Unauthorized modication of the venting system.
• Installation of any component part not manufactured
or approved by Vermont Castings Group.
• Installation other than permitted by these instruc-
tions.

Horizontal sections of this vent system
require a minimum of 3" (76 mm)clearances
to combustibles at the top of the ue and 1"
(25 mm) clearance at the sides and bottom
until the ue penetrates the outside wall. A
minimum 1" clearance all around the ue
is acceptable at this point of penetration.
WARNING
Unless the vertical run is 71⁄2' (2.3 m) or
higher from oor of replace, the clearance
for horizontal run is 1" on all sides.
For models purchased after 4/16/15, please see addendum.
VENT INSTALLATION
INSTALLATION PLANNING
There are two basic types of direct-vent installation:
• Horizontal Termination
• Vertical Termination
It is important to select the proper length of vent pipe for
the type of termination you choose. It is also important to
note the wall thickness.
FOR HORIZONTAL TERMINATION
Select the amount of vertical rise desired. All horizontal run
of venting must have 1⁄4" rise for every 12" of run towards
the termination below 71⁄2 feet of vertical rise from the oor
of the replace. With 71⁄2 feet or more vertical rise from
the oor of the replace, the horizontal run may run level.
NEVER run vent piping down.
You may use up to three 90° elbows in this vent conguration. Refer to Vertical/Horizontal Termination Congurations
on Page 15.
Horizontal venting which incorporates the twist lock pipe
must be installed on a level plane without an inclining or
declining slope.
FOR VERTICAL TERMINATION
Measure the distance from the replace oor to the ceiling. Add the ceiling thickness, the vertical rise in an attic
or second story, and allow for sufcient vent height above
the roof line.
NOTE: You may use two 45° elbows in place of a 90° elbow.
You must follow rise to run ratios when using 45° elbows.
The appliance is approved for use with three 90° elbows
maximum or a combination of 90° and 45° elbows up to
a maximum of 270°.
WDV Series Gas Fireplace
Never run the vent pipe level down. This
may cause excessive temperatures which
could cause a re.
WARNING
For two-story applications, restops are required at each
oor level. If an offset is needed in the attic, additional pipe
and elbows will be required.
You may use a chase with a vent termination with exposed
pipe on the exterior of the house.
Refer to Installing A Vent System in an Outside Chase
below. If pipe is enclosed in chase, it is not exposed.
It is very important that the venting system maintain its bal-
ance between the combustion air intake and the ue gas
exhaust. Certain limitations apply to vent congurations
and must be strictly followed.
INSTALLING A VENT SYSTEM IN AN
OUTSIDE CHASE
A chase is a vertical boxlike structure built to enclose
venting that runs along the outside of a building. A chase
is required for such venting.
Always maintain minimum clearances around
vent systems. The minimum clearances to
combustibles for horizontal and vertical vent
pipe are 1" at the top, sides and bottom of the
vent system. Do not pack the open air spaces
with insulation or other materials. This could
WARNING
cause high temperatures and may present a re
hazard.
When installing in a chase, you should
insulate the chase as you would the outside
walls of your home. This is especially
important in cold climates. Insulation
should be considered a combustible
NOTICE
material. Maintain proper clearances to all
combustible materials.
Treatment of restops and construction of
the chase may vary from building type to
building type. These instructions are not
substitutes for the requirements of local
NOTICE
building codes. You must follow all local
building codes.

HOW TO USE THE VENT GRAPH
The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the
relationship between the vertical and horizontal dimensions
of the vent system.
1. Determine the height of the center of the horizontal vent
pipe exiting through the outer wall. Using this dimension
on the Sidewall Vent Graph below, locate the point
intersecting with the slanted graph line.
2. From the point of this intersection, draw a vertical line
to the bottom of the graph.
3. Select the indicated dimension, and position the re-
place in accordance with same.
Example: If the vertical dimension from the oor of the
replace is 11' (3.4 m) the horizontal run to the face of
the outer wall must not exceed 16' (4.9 m).

VERTICAL/HORIZONTAL TERMINATION
CONFIGURATIONS
Since it is very important that the venting system
maintain its balance between the combustion air intake
and the ue gas exhaust, certain limitations as to vent
congurations apply and must be strictly adhered to.
The Vent Graph, showing the relationship between vertical
and horizontal side wall venting, will help to determine the
various dimensions allowable. Figure 10
NOTE: Horizontal and vertical sections of this vent system
require a minimum of 1" clearance to combustibles at the
top, sides and bottom.
When vent exits through foundations less than 20" below
outcrop, the termination must be ush up with outcropped
wall above.
It is best to locate the replace in such a way that minimizes
the number of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent
pipe from the ue collar of the replace (or the top of the
Transition Elbow) to the face of the nished outside wall.
• The maximum number of 90° elbows per side wall
installation is three (3). Figure 14
• A minimum of 12" is required before a 90° elbow. If a 90°
elbow is tted directly after 12" vertical section mounted
to the top of the replace, the maximum horizontal vent
run before the termination or a vertical rise is 36” (914
mm). Figure 15

• For each 45° elbow installed in the horizontal run, the
length of the horizontal run MUST be reduced by 18" (45

BELOW GRADE INSTALLATIONS
When it is not possible to meet the required vent terminal
clearances of 12" above grade level, a snorkel kit is recommended. It allows installation depth down to 7" (178
mm) below grade level. The 7" (178 mm) is measured
from the center of the horizontal vent pipe as it penetrates
through the wall.
Ensure that sidewall venting clearances are observed.
If venting system is installed below ground, we recommend a window well with adequate and proper drainage
to be installed around the termination area.
If installing a snorkel, a minimum 12" vertical rise is neces-
sary. The maximum horizontal run with the 12” vertical pipe
is 36". This measurement is taken from the collar of the
replace (or transition elbow) to the face of the exterior wall.
See the Sidewall Venting Graph for extended horizontal
run if the vertical exceeds 12".
1. Establish vent hole through the wall.
2. Remove soil to a depth of approximately 16" below base
of snorkel. Install drain pipe. Install window well (not
supplied). Rell hole with 12" of coarse gravel leaving
a clearance of approximately 4" below snorkel. Figure
18
3. Install vent system.
4. Ensure a watertight seal is made around the vent pipe
coming through the wall.
5. Apply high temperature sealant caulking (supplied)
around the 5" and 8" snorkel collars.
6. Slide the snorkel into the vent pipes and secure to the
wall.

INSTALLATION FOR VERTICAL TERMINATION
VENTING INSTALLATION
1. Determine the route your vertical venting will take. If
ceiling joist, roof rafters or other framing will obstruct
the venting system, consider an offset. Refer to Figure
22 to avoid cutting load bearing members.
For optimal ame appearance, a restrictor disk is necessary
on straight vertical runs of 10' of more.
• Runs may not incorporate elbows.
• The disk is part number 56D3027 and is included in
installation manual packet.
• Drop the disk into a 5" inner collar before installing the
rst section of ue or install at the last section before
installing the termination.
• An additional disk may be installed on runs of 35' or more.
Rotate disks perpendicular to each other.
NOTE: Pay special attention to these installation instructions
for required clearances (air space) to combustibles when
passing through ceilings, walls, roofs, enclosures, attic
rafters, etc. Do not pack air spaces with insulation. Also
note maximum vertical rise of the venting system and any
maximum horizontal offset limitations. Offsets must fall
within the parameters shown in Figures 21 and 22.
2. Set replace in desired location. Drop a line plumb down
from the ceiling to the position of the ue exit. Mark the
center point where the vent will penetrate the ceiling.
Drill a small locating hole a this point.
Drop a plumb line from the inside of the roof to the ceiling
locating hole in the ceiling. Mark the center point where
the vent will penetrate the roof. Drill a small locating hole
at this point.
FLAT CEILING INSTALLATION
1. Cut a 101⁄2" (241 mm) square hole in the ceiling using
the locating hole as a center point The opening should
be framed to 101⁄2" x 101⁄2" (241 x 241 mm) inside dimen-
sions as shown in Figure 24 using framing lumber the
same size as the ceiling joist. If the area above the
ceiling is an insulated ceiling or a room, nail restop from
the top side. This prevents loose insulation from falling
into the required clearance space. Figure 23. Otherwise,
install restop below the framed hole. Figure 24
2. Assemble the desired lengths of pipe and elbows nec-
essary to reach from the burner system ue up through
the restop. Be sure pipe and elbow connections are
fully twist-locked.

3. Cut a hole in the roof using the locating hole as a center
point. (Cover any exposed open vent pipes before
cutting hole in roof). The 101⁄2"x101⁄2" (241 x 241 mm)
hole must be measured on the horizontal. Actual length
may be larger depending on the pitch of the roof. There
must be a 1" minimum clearance from the vent pipe to
combustible materials. (Insulation should be considered
a combustible material).
4. Connect a section of pipe and extend up through the
hole.
NOTE: If an offset is needed to avoid obstructions,
you must support the vent pipe every three (3) feet.
Use wall straps for this purpose. Figure 22. Whenever
possible, use 45° elbows instead of 90° elbows. The
45° elbow offers less restriction to the ow of the ue
gases and intake air.
5. Place the ashing over the pipe section(s) extending
through the roof. Secure the base of the ashing to
the roof and framing with roong nails. Be sure roong
material overlaps the top edge of the ashing. There
must be a 1" clearance from the vent pipe to combustible
materials.
6. Continue to add pipe sections until the height of the vent
cap meets the minimum building code requirements.
NOTE: You must increase vent height for steep roof
pitches. Nearby trees, adjoining roof lines, steep
pitched roofs, and other similar factors may cause
poor draft or down-drafting in high winds. Increasing
the vent height may solve this problem.
NOTE: If the vent pipe passes through any occupied
areas above the rst oor, including storage spaces
and closets, you must enclose pipe. You may frame and
sheetrock the enclosure with standard construction
material. Make sure to meet the minimum allowable
clearances to combustibles. Do not ll any of the
required clearance spaces with insulation.
