VENTING INSTALLATION
Installation Precautions
Installation Planning
WARNING: Read all instructions completely and
thoroughly before attempting installation. Failure to
doso couldresultinserious 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 pipe to pipe connections with
hightemperaturesilicone(600°F/316°C)every timea
vent connection is made. 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
installation. Before installing vent kit, the installer must read this
fireplace manual and vent kit instructions.
Only a qualified installer or 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
The following actions will void the warranty on your venting
system:
• Installation of any damaged venting component
• Unauthorized modification of the venting system
• Installationofany component part not manufacturedor approved
by DESA International
• Installation other than as instructed by these instructions
VENTING INSTALLATION
WARNING: This gas fireplace and vent assembly
must be vented directly to the outside. The venting
system must NEVER be attached to a chimney serv-
ingaseparatesolidfuelburningappliance.Eachgas
appliance must use a separate vent system. Do not
use common vent systems.
WARNING: Horizontal sections of this vent sys-
tem require a minimum clearance of 2" from the top
of the vent pipe and 1" minimum to the sides and
bottom. Vertical sections of this system require a
minimumof1"clearancetocombustiblematerialson
all sides of the vent pipe.
INSTALLATION PLANNING
There are two basic types of direct-vent installation:
• Horizontal Termination
• Vertical Termination
Itis important to select theproper length of vent pipefor 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. The horizontal run of venting must have 1/4" rise for every
12" of run towards the termination.
WARNING: Never run the vent downward as this
may cause excessive temperatures which could
cause a fire.
You may use one or two 90° elbows in this vent configuration. See
Horizontal Termination Configurations on page 12.
For Vertical Termination: Measure the distance from the fireplace
flue outlet to the ceiling. Add the ceiling thickness, the vertical rise
inanatticorsecondstory,andallowforsufficientventheightabove
the roofline. You may use one or two 90° elbows in this vent
configuration. See Vertical Termination Configurations on pages
14 and 15.
Note: You may use two 45° elbows in place of a 90° elbow. You
must follow rise to run ratios when using 45° elbows.
For two-story applications, firestops are required at each floor
level.Ifan offset is needed inthe attic, additional pipe andelbows
will be required.

tal run is 20' with 8' vertical rise (see Installation for Horizontal
Termination,pages10through12).Themaximumverticalrunis30'
(see Installation for Vertical Termination, pages 12 through 15).
It is very important that the venting system maintain its balance
between the combustion air intake and the flue gas exhaust. Certain
limitationsapplytoventconfigurationsandmustbestrictlyfollowed.
NOTICE: Do not seal termination cap to pipe. Cap
must be removable for servicing vent system.

VENTING INSTALLATION
Continued
Note: When installing in a chase, you should insulate the chase as
you would the outside walls of your home. This is especially
importantin coldclimates. Minimumclearance betweenvent pipes
and combustible materials such as insulation is 1" (2.5cm).
After framing the chase (see Framing on pages 5 and 6) install the
vent system by following the installation instructions.
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 blocked or obstructed.
CAUTION: Horizontally terminated venting con-
figurationsrequireonefootofverticalrisefromthe45°
elbow before any horizontal run can be made. Failure
tomeetventingrequirementsmaycauseperformance

ing statement on page 9.) Push the pipe sections together and
twist one section clockwise approximately one-quarter turn
until the sections are fully locked. See Figure 16. Note: Hori-
zontal runs of vent must be supported every three feet. Use
wall straps for this purpose.
Flexible vent pipe must be installed with spacer springs every
12" (30.5cm). See Figure 16, page 10.All connections must be
clamped tightly and sealed with high temperature silicone seal-
ant as specified in the second warning statement on page 9.
3. Attach vent pipe assembly to the fireplace. Set fireplace 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" (19.1cm)
diameter hole is acceptable). See Figure 17. The center of
the hole should line up with the center-line of the horizontal
rigid vent pipe. Cut a 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 17).
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 18). Note : Re-
placethewoodscrews withappropriatefastenersfor stucco,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 sidingmaterials. 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 (seeFigure 19).Thesiding standoff must
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 20).
6. Carefully move the fireplace with vent assembly attached to-
ward the wall and insert the vent pipe into the horizontal termi-
nation. The pipe overlap should be a minimum of 11/4" (3.2cm).
Fasten all vent pipe connections (except vent cap) with screws
provided. Refer to Framing on pages 5 and 6 for instructions
on securing unit to framing or floor.
7. Combustible Exterior Wall Only: Slide the wall firestop
against the interior wall surface and attach with screws pro-
vided (see Figure 20).

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 24, page 13) to avoid
cutting loadbearing members. Note: Pay special attention to
theseinstallation instructions for requiredclearances (air space)
to combustibles when passing through ceilings, walls, roofs,
enclosures, attic rafters, etc. Do not pack air spaces with insu-
lation.Also note maximum vertical rise of the venting system
and any maximum horizontal offset limitations. Offsets must
fall within the parameters shown in Figure 13 on page 8.
2. Set the fireplace in desired location. Drop a plumb line down
from the ceiling to the position of the fireplace 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.

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 (91.4cm). Use wall straps
for this purpose (see Figure 24). Whenever possible, use 45°
elbows instead of 90° elbows. The 45° elbow offers less re-
striction 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 framing
with roofing nails. Be sure roofing material overlaps the top
edge of the flashing as shown in Figure 24. There must be a 1"
(2.5cm) 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 13 on page 8. 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 with high temperature silicone sealant as specified in the
second warning statement on page 9.
Note: Iftheventpipepassesthroughanyoccupiedareasabovethefirst

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" (0.3cm) larger than the support box outline
(see Figure 26).
3. Lower the support box through the hole in the roof until the
bottom of the box extends at least 2" (5.1cm) below the ceil-
ing (see Figure 26).Align the support box vertically and hori-
zontallyusing a level.Temporarilytack the support boxin place
through the inside walls and into the roof sheathing.
Flat Ceiling Installation
1. Cut a 10" square hole in the ceiling using the locating hole as a
centerpoint. Theopening should be framed to10"x10"(25.4cm
x 25.4cm) inside dimensions, as shown in Figure 17 on page 11
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
firestop below the framed hole. The firestop should be installed
with no less than three nails per side (see Figure 25).
2. Assemblethedesiredlengthsofpipeandelbowsnecessarytoreach
from the fireplace flue up through the firestop. All connections
must be sealed with high temperature silicone sealant as specified
in the second warning statement on page 9. Be sure all pipe and
elbow connections are fully twist-locked (see Figure 16, page 10).
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 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
ventpipe to combustiblematerials. Frame the openingas shown
in Figure 17 on page 11.

ing the use of teflon tape. Complete your gas line installation
by connecting incoming gas line with flexible gas line. Se-
cure tightly with a wrench, but Do NOT overtighten.
WARNING: All gas piping and connections must
be tested for leaks after the installation is completed.
Afterensuringthat thegasvalveisopen,apply a soap
and water solution to all connections and joints. If
bubbles appear, leaks can be detected and corrected.
Do not use an open flame for leak testing and do not
operate any appliance if a leak is detected.
WARNING: Improper installation, adjustment, al-
teration, service, or maintenance can cause injury or
property damage. Refer to this manual. For assis-
tance or additional information, consult a qualified

PILOT ASSEMBLY
ADJUSTMENT
The pilot assembly is factory preset for the proper flame height.
Alteration to these settings may have occurred during shipping and
handling. If this is the case, some minor adjustment may be neces-
saryandshouldbedonebyaqualifiedtechnician.Toaccessthepilot
assembly,theglassdoormustbeopened.Thepropersettingsforthe
thermopile height should be at a distance of 3/8" (.95cm) to 1/2"
(1.3cm) from the pilot flame as shown in Figure 47.

BURNER FLAME ADJUSTMENT
The air shutter, located at the underside of the main burner (see
Figure 48), has been factory preset to the proper air-to-gas ratio
whichresults in aneven, clean burningflame across theburner (see
Figure 49). If readjustment is necessary, you can restore the proper
air-to-gasratiobylooseningtheairshutterscrewandrotatingtheair
shutter until the proper flame setting is achieved (the shutter's
normal setting is “full opened”. Do not forget to retighten the air
shutter screws.
