WARNING: Read all instructions completely and
thoroughly before attempting installation. Failure to
doso couldresultinseriousinjury, 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:Sealallpipetopipeconnections.Seal
only the outer pipe connections with high tempera-
ture 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 reseal 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:
• Installation of any damaged venting component
• Unauthorized modification of the venting system
• Installationof any component part not manufactured or approved
by DESA
• Installation other than as instructed by these instructions
VENTING INSTALLATION
WARNING: This stove with burner system and
ventassemblymustbeventeddirectlytotheoutside.
The venting system must NEVER be attached to a
chimney serving a separate solid fuel burning appli-
ance. Each gas appliance must use a separate vent
system. Do not use common vent systems.
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
ventpipeinthisconfiguration.SeeHorizontalTerminationConfigu-
rations 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
through 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.
Fortwo-storyapplications, firestopsare required ateach floorlevel
(seeFigure33,page16).Ifanoffsetisneededintheattic,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. See Installing Vent System in a Chase, page 13.
Your stove with direct-vent burner system has been tested for a
maximumhorizontalrun of20' with 8'vertical rise (seeInstallation
for Horizontal Termination, pages 13 through 15). The maximum
vertical run is 40' (see Installation for Vertical Termination, pages
16 through 19).
It is very important that the venting system maintain its balance
between the combustion air intake and the flue gas exhaust. Certain
limitationsapplytoventconfigurationsandmustbestrictlyfollowed.
WARNING: Never run thevent pipe downward as
this may cause excessive temperatures which could
cause a fire.

INSTALLATION FOR HORIZONTAL
TERMINATION
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 external
wall firestop. If installing the snorkel termination below grade
(basement applications), you must provide proper drainage 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 fittings
havefourlockinglugs(indentations).Theselugswillslidestraight
into matching slots on the male ends of adjacent pipes and fit-
tings. (All connections must be sealed with high temperature sili-
conesealantas specified inthesecond warning statementonpage
12.) Push the pipe sections together and twist one section clock-
wise approximately one-quarter turn until the sections are fully
locked. See Figure 24. Note: Horizontal runs of vent must be
supported every three feet. Use wall straps for this purpose.

Figure 28 - Connecting Vent Cap with Horizontal Vent Pipe
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"(25.4cm) square hole (for noncombus-
tiblematerialsuchas masonryblockor concrete, a71/2"(19.1cm)
diameter hole is acceptable). See Figure 25. The center of the
hole should line up with the center-line of the horizontal rigid
ventpipe. Cuta 10"x10" (25.4cm x 25.4cm) square hole through
combustible exterior wall (7 1/2" [19.1cm] diameter hole if
noncombustible). Frame as necessary (see Figure 25).
4. Noncombustible Exterior Wall: Apply a bead of non-harden-
ing mastic around the outside edge of the vent cap. Position the
vent cap in the center of the 7 1/2" (19.1cm) hole on the exterior
wall with the arrow on the vent cap pointing up. Attach the vent
cap with four wood screws provided (see Figure 26).
Note : Re-
placethewoodscrewswithappropriatefastenersforstucco,brick,
concrete, or other types of siding.
Combustible ExteriorWall: For vinyl siding, stucco, or wood
exteriors, a siding standoff must be installed between the vent
cap and exterior wall. The siding standoff prevents excessive
heat from damaging siding materials. Siding materials must be
cut to accommodate standoff. Bolt the vent cap to the stand-
off. Apply non-hardening mastic around outside edge of the
standoff. Position the standoff/cap assembly in the center of
the 10" (25.4cm) square hole and attach to exterior wall with
woodscrews provided (seeFigure27).The siding standoffmust
sit flush against the exterior fascia material.
5. Combustible Exterior Wall Only: Slide the interior wall
firestop over the vent pipe before connecting the horizontal
run to the vent cap (see Figure 28).
6. Carefully move the fireplace with vent assembly attached toward
the wall and insert the vent pipe into the horizontal termination.
The pipe overlap should be a minimum of 1 1/4" (3.2cm). Fasten
all vent pipe connections (except vent cap) with screws provided.
7. Combustible Exterior Wall Only: Slide the wall firestop
against the interior wall surface and attach with screws pro-
vided (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 load
bearing members. Note: Pay special attention to these installa-
tion instructions for required clearances (air space) to combus-
tibles when passing through ceilings, walls, roofs, enclosures,
attic rafters, etc. Do not pack air spaces with insulation. Also
notemaximum verticalrise of theventing systemand any 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" (25.4cm) square hole in the ceiling using the locat-
ing hole as a center point. The opening should be framed to
10"x10" (25.4cm x 25.4cm) 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 pre-
vents loose insulation from falling into the required clear-
ance space. Otherwise, install firestop below the framed hole.
The firestop should be installed 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.
(Coveranyexposed open ventpipes before cuttingholein roof.)
The 10"x10" (25.4cm x 25.4cm) hole must be measured on
the horizontal; actual length may be larger depending on the
pitch of the roof. There must be a 1" clearance from the vent
pipe to combustible materials. 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.
7. Twist-lock the vent cap onto the last section of vent pipe and
seal outer pipe connection with high temperature silicone seal-
ant as specified in the second warning statement on page 12.

Cathedral Ceiling Installation
1. Remove shingles or other roof covering as necessary to cut the
rectangular hole for the support box. Mark the outline of the
cathedral ceiling support box on the roof sheathing using the
locating hole as a center point.
2. Cut the hole 1/8" larger than the support box outline (see
Figure 34).
3. Lower the support box through the hole in the roof until the
bottom of the box extends at least 2" below the ceiling (see
Figure 34). Align the support box vertically and horizontally
usinga level.Temporarily tack the support boxin place through
the inside walls and into the roof sheathing.
4. Using tin snips, cut the support box from the top corners down
to the roofline and fold the resulting flaps over the roof sheath-
ing(see Figure 35).Applya beadof nonhardening masticaround
the top edges of the support box to make a seal between the box
and the roof. Nail in place with roofing nails. Remove any com-
bustible material that might be inside of the support box.
