LOCATION OF VENT TERMINATION
When locating vent termination, it is important to observe the
minimum clearances shown in Figure 21, page 11.
*Check with local codes or with the current CAN/CSA B149[.1 or
.2] Installation Codes for Canada or the USA Installations follow
the current National Fuel Gas Code, ANSI Z223.1/NFPA 54.
Your stove with burner system is approved to be vented either
through the side wall, or vertically using the following guidelines:
• Use only venting components or kits specifically approved for
use with this stove and burner system (see Parts Lists for Vent-
ing Kits and Components, page 19).
IMPORTANT: Do not mix venting components made by differ-
ent manufacturers.
• Minimum clearance between vent pipes and combustible mate-
rials is 1" (25 mm), except where stated otherwise.
• Do not recess venting terminations into a wall or siding.
• Install horizontal venting with a 1/4" rise for every 12" of
run toward the termination.
• You may paint the vent termination with 450ºF (232ºC) heat-
resistant paint to coordinate with the exterior finish.
• There must not be any obstruction such as bushes, garden sheds,
fences, decks, or utility buildings within 24" from the front of
the termination cap.
• Do not locate termination cap where excessive snow or ice build
up may occur. Be sure to clear vent termination area after snow
falls to prevent accidental blockage of venting system. When
using snow blowers, do not direct snow towards vent termina-
tion area.
• You must maintain minimum wall and ceiling clearances shown
in Figures 3 and 4, page 5.
• If installing horizontal vent termination cap on an exterior wall
with siding, you must us a vinyl siding standoff (see Figure 27,
page 14).

WARNING: Read all instructions completely and
thoroughly before attempting installation. Failure to
dosocould resultinserious injury,propertydamage
or loss of life. Operation of improperly installed and
maintained venting system could result in serious
injury, property damage or loss of life.
WARNING: Seal all vent connections. Seal only
the outer pipe connections with high temperature
silicone (600°F/316°C). Before joining elbows and
pipes, apply a bead of high temperature silicone
sealant (GE RTV 106/Loctite RTV 81585) to the male
end of the elbow or pipe. High temperature silicone
must also be used to re-seal any connections after
maintenance to venting system.
NOTICE: Failure to follow these instructions will void
the warranty.
INSTALLATION PRECAUTIONS
Consult local building codes before beginning the installation. The
installer must make sure to select the proper vent system for installa-
tion. Before installing vent kit, the installer must read this stove and
burner system manual and vent kit instructions.
Only a qualified 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 roof tops
• Be aware of electrical wiring locations in walls and ceilings
Thefollowingactionswillvoidthewarrantyonyourventingsystem:

WARNING: Horizontal sections of this vent system
require a minimum clearance of 2" from the top of the
pipe and 1" minimum to the sides and bottom. Vertical
sections of this system require a minimum of 1" clear-
ance to combustible materials on all sides of the pipe.
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
terminationyouchoose.Itisalsoimportanttonotethewallthickness.
For Horizontal Termination: Select the amount of vertical rise
desired. The horizontal run of venting must have 1/4" rise for every
12" of run towards the termination.
You may use up to two 90°elbows on any single horizontal run of
vent pipe in this confuguration. See Horizontal Termination Con-
figurations on page 15.
For Vertical Termination: Measure the distance from the burner
systemflueoutlettotheceiling.Addtheceilingthickness,thevertical
rise in an attic or second story, and allow for sufficient vent height
above the roofline. You may use one or two 90°elbows in this vent
configuration. See Vertical Termination Configurations on pages 17
and 19.
Note: You may use two 45°elbows in place of a 90°elbow. You
must follow rise to run ratios when using 45°elbows.

INSTALLATION FOR HORIZONTAL
TERMINATION
1. Determine the route your horizontal venting will take. Note:
The location of the horizontal vent termination on the exterior
wall must meet all local and national building codes and must
not be easily blocked or obstructed.
Snorkel terminations are available for terminations requiring a
vertical rise on the exterior of the building (see Figures 22 and
23). Snorkel kit VKS-47-K is also available (see page 19). Fol-
low the same installation procedures used for standard horizon-
tal termination with the exception of the external wall firestop.
The snorkel termination does not require the use of the exter-
nal wall firestop. If installing the snorkel termination below
grade (basement applications), you must provide proper drain-
age to prevent water from entering the snorkel termination (see
Figure 23). Do not back fill around the snorkel termination.
2. Vent pipes and fittings have special twist-lock connections.As-
semble the desired combination of pipe and elbows to the appli-
ance adaptor with pipe seams oriented towards the wall or floor.
Twist-lock Procedure: The female ends of the pipes and fit-
tings have four locking lugs (indentations). These lugs will
slide straight into matching slots on the male ends of adjacent
pipes and fittings. (All connections must be sealed with high
temperature silicone sealant as specified in the second warn-
ing statement on page 12.) Push the pipe sections together and
twist one section clockwise approximately one-quarter turn
until the sections are fully locked. See Figure 24. Note: Hori-
zontal runs of vent must be supported every three feet. Use
wall straps for this purpose.

Note: 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. Minimum air space clearance between
vent pipes and combustible materials and/or insulation is 1".

3. Attach vent pipe assembly to the burner system. Set stove in
front of it’s permanent location to insure minimum clearances.
Mark the wall for a 10" square hole (for noncombustible ma-
terial such as masonry block or concrete, a 7 1/2" diameter hole
is acceptable). See Figure 25. The center of the hole should
line up with the center-line of the horizontal vent pipe. Cut a
10"x10" (254mm x 254mm) square hole through combustible
exterior wall (7 1/2"[190mm] diameterhole if noncombustible).
Frame as necessary (see Figure 25).
4. ForCombustibleExterior:Apply abeadof non-hardeningmas-
tic around the outside edge of the exterior wall firestop. Posi-
tion the external wall firestop withinthe 10" square opening on
the exterior wall with firestop flanges inside the opening. At-
tach using screws provided as shown in Figure 26. Position
the vent termination in the center of exterior wall firestop with
arrow on termination pointing up.
For Noncombustible Exterior: Apply a bead of non-harden-
ing mastic around the outside edge of the vent termination.
The exterior wall firestop will not be necessary for this appli-
cation. Position the termination cap in the center of the 7 1/2"
hole on exterior wall with arrow on termination pointing up.
Attach the vent termination with four wood screws supplied
(see Figure 26). Note : Replace the wood screws with appropri-
ate fasteners for stucco, brick, concrete, or other types of siding.
5. Use of a vinyl siding standoff is required when vinyl siding,
cedar shake, or other painted wood surfaces could melt, peel,
or discolor from trapped or wind driven flue exhaust (exces-
sive heat) near vent termination. The vinyl siding standoff re-
places the outer firestop between the vent termination and the
exterior wall to protect these exterior wall treatments. Bolt the
vent cap to the standoff. Apply non-hardening mastic around
outside edge of the standoff. Position standoff within the 10"
square opening on theexterior wall. Use wood screws provided
to attach the standoff. See Figure 27.
6. Slide the interior wall firestop over the vent pipe before con-
necting the horizontal run to the vent cap (see Figure 28).
7. Carefully move the stove with vent assembly attached toward
the wall and insert the vent pipe into the horizontal termina-
tion. The pipe overlap should be a minimum of 1 1/4". Apply
silicone to the outer pipe connection. Fasten all vent connec-
tions with screws provided.
8. Slide the interior wall firestop against the interior wall surface
and attach with screws provided (see Figure 28).

1. Determine the route your vertical venting will take. If ceiling
joists, roof rafters, or other framing will obstruct the venting
system, consider an offset (see Figure 32) to avoid cutting
loadbearing members. Note: Pay special attention to these in-
stallationinstructions forrequiredclearances (airspace) tocom-
bustibleswhen passingthroughceilings,walls,roofs, enclosures,
attic rafters, etc. Do not pack air spaces with insulation. Also
notemaximum vertical riseof theventing systemandany maxi-
mum horizontal offset limitations. Offsets must fall within the
parameters shown in Figures 36 through 38, pages 17 and 18.
2. Set the stove in desired location. Drop a plumb line down from
the ceiling to the position of the burner system exit flue. Mark
the center point where the vent will penetrate the ceiling. Drill
a small locating hole at this point.
Drop a plumb line from the inside of the roof to the 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 10" square hole in the ceiling using the locating hole as a
centerpoint.The openingshouldbe framedto 10"x10"(254mm
x 254mm) inside dimensions, as shown in Figure 25 on page
14 using framing lumber the same size as the ceiling joists. If
the area above the ceiling is an insulated ceiling or a room, nail
firestop from the top side. This prevents loose insulation from
falling into the required clearance space. Otherwise, install
firestopbelow theframedhole.The firestopshould beinstalled
with no less than three nails per side (see Figure 33).
2. Assemble the desired lengths of pipe and elbows necessary
to reach from the burner system flue up through the firestop.
All connections must be sealed with high temperature sili-
cone sealant as specified in the second warning statement on
page 12. Be sure all pipe and elbow connections are fully
twist-locked (see Figure 24, page 13).
3. Cut a hole in the roof using the locating hole as a center point.
(Coverany exposedopenvent pipesbefore cuttingholein roof.)
The 10"x10" hole must be measured on the horizontal; actual
length may be larger depending on the pitch of the roof. There
mustbea 1"clearancefrom thevent pipe tocombustible mate-
rials. Frame the opening as shown in Figure 25 on page 14.
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 3 feet. Use wall straps for this
purpose (see Figure 32). Whenever possible, use 45°elbows
instead of 90°elbows. The 45°elbow offers less restriction
to the flow of the flue gases and intake air.
5. Place the flashing over the pipe section(s) extending through
the roof. Secure the base of the flashing to the roof and fram-
ing with roofing nails. Be sure roofing material overlaps the
top edge of the flashing as shown in Figure 32. 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 described in
Figure 21 on page 11. Note : You must increase vent height
for steep roof pitches. Nearby trees, adjoining rooflines, 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.
