Improper use of this replace
can cause serious injury or death
from burns, re, explosions,
electrical shock and carbon
monoxide poisoning.
DANGER: Carbon monoxide
poisoning may lead to death!
This replace must be installed by a qualied (cer-
tied or licensed) service person. It has a sealed
gas combustion chamber that uses a coaxial pipe
(pipe within a pipe and having the same center)
venting system. It brings in fresh air for combus-
tion through the outer pipe and combustion gases
are exhausted through the inner pipe. If the glass
door assembly and venting pipe are not properly
seated, connected and sealed, carbon monoxide
leakage (spillage) can occur.

116646-01D 3
Carbon Monoxide Poisoning: Early signs of carbon
monoxide poisoning resemble the u, with head-
aches, dizziness or nausea. If you have these signs,
the replace may not be working properly. Get
fresh air at once! Have replace serviced. Some
people are more affected by carbon monoxide than
others. These include pregnant women, people with
heart or lung disease or anemia, those under the
inuence of alcohol and those at high altitudes.
Natural and Propane/LP Gas: Natural and pro-
pane/LP gases are odorless. An odor-making agent
is added to the gas. The odor helps you detect a gas
leak. However, the odor added to the gas can fade.
Gas may be present even though no odor exists.
Make certain you read and understand all warnings.
Keep this manual for reference. It is your guide to
safe and proper operation of this replace.

PRODUCT FEATURES
These are a few facts that can help you understand
and enjoy your direct-vent replace:
• The venting system may be routed to the out-
side of your home in several ways. It may vent
through the roof (vertical) or it may vent to an
outside/exterior wall (horizontal). The vent
pipe installation is very important to allow for
proper operation. You must follow the venting
instructions very carefully for either vertical or
horizontal applications.
• This replace may be installed in any room of
your house provided all local codes and these
installation instructions are followed.
• This replace does not require electricity to
operate.
• Only the blower requires electricity if installed.
If you plan to install the blower at a later date,
outlet must be wired at the bottom of the re-
place when framing.
• A piezo ignitor and ceramic electrode create
sparks to ignite the pilot light. It does not require
any matches, batteries or any other sources of
ignition to light the pilot.
• Each time you turn on your replace, you may
notice some amount of condensation on the in-
side of the replace glass. This is normal and will
disappear after 10-20 minutes of operation.
• Your direct-vent gas replace system (replace
and venting) is a balanced and sealed gas op-
erating unit. It requires approximately 10-20
minutes of operating time before the ame
pattern stabilizes.
• Fireplaces with the sufx of -HA have been
designed to operate at altitudes of 4000 feet
and above.

PRE-INSTALLATION
PREPARATION
LOCATION AND SPACE
REQUIREMENTS
Determine the safest and most efcient location
for your DESA direct-vent replace. Make sure
that rafters and wall studs are not in the way of the
venting system. Choose a location where the heat
output is not affected by drafts, air conditioning
ducts, windows or doors. Figure 2 shows some
common locations. Be aware of all restrictions and
precautions before deciding the exact location for
your replace and termination cap.
When deciding the location of your replace,
follow these rules:
• Do not connect this replace venting to a chim-
ney ue serving a separate solid-fuel burning
replace or appliance.
• Due to high temperatures, do not locate this
replace in high trafc areas, windy or drafty
areas or near furniture or draperies.
• Proper clearances must be maintained.
• If your replace is to be installed directly on
carpeting, vinyl tile or any combustible mate-
rial other than wood, it must be installed on a
metal or wood panel extending the full width
and depth of the replace. See Figure 3.
• Your replace is designed to be used in zero
clearance installations. Wall or framing material
can be placed directly against any exterior sur-
face on the back, sides or top of your replace,
except where standoff spacers are integrally
attached. If standoff spacers are attached to your
replace, these spacers can be placed directly
against wall or framing material. See framing
details on page 6.
• If you plan on installing a television or enter-
tainment center recessed above your replace, it
is recommended that you maintain a minimum
18" above top of louver opening.
• When locating termination cap, it is important
to observe the minimum clearances shown in
Figure 7, page 7.
• If recessing into a wall, you can avoid extra
framing by positioning your replace against
an already existing framing member.
• Do not recess termination cap into a wall or
siding.
• You may paint the termination cap with 450º F
heat-resistant paint to coordinate with the exterior
nish.

• 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 termination area.
• For horizontal installations above 2,000 feet, it
is recommended that a 12" extension pipe be
added before starter elbow and a round hori-
zontal termination be used (see High Altitude
Installation, page 16).

VENTING INSTALLATION
INSTRUCTIONS
NOTICE: Read these instruc-
tions completely before at-
tempting installation.
These models are tested and approved for use
with DESA (direct-vent) pipe components and
terminations.
The venting system must terminate on the outside of
the structure and can not be attached to a chimney
or ue system serving a separate solid fuel or gas
burning appliance. A direct-vent appliance must
have its own venting system. DO NOT common
vent this appliance.
These models are approved to be vented either
horizontally through an outside wall or vertically
through a roof or chase enclosure using the fol-
lowing guidelines:
• When venting system terminates horizontally
on an outside wall, you may install a standoff
if the termination cap is to be installed directly
on a combustible nish such as vinyl, wood,
stucco, etc.
• Never run the vent downward as this may
cause excessive temperatures which could
cause a re.
• Vent pipe air space clearances to combustibles
are 1" on all sides except on the horizontal
sections, which requires 2" clearance from
the top of the pipe. Where the termination cap
penetrates a combustible wall, 1" air space
clearance is required.
• Snorkel terminations are required when
minimum clearance to grade cannot be met (see
Figure 16 on page 12).
• Have replace and selected vent components on
hand to help determine the exact measurements
when elbowing or offsetting. Always use wall
restops when penetrating walls and restops
when penetrating ceilings or attic spaces.
• If using a venting conguration of only hori-
zontal venting with no vertical run, a 1/4" rise
for every 12" of run toward the termination is
required.
• For installation of replace at elevations of 4000
feet or greater, pay special attention to venting
requirement recommendations.
WARNING: Read all instruc-
tions completely and thoroughly
before attempting installation.
Failure to do so could result in
serious injury, property damage
or loss of life.
NOTICE:Failuretofollowthesein-
structions will void the warranty.
NOTICE: Do not seal vent cap
to pipe. Cap must be removable
for service.
INSTALLATION PRECAUTIONS
• 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 modication of the venting sys-
tem (Do not cut or alter vent components)
• Installation of any component part not manu-
factured or approved by DESA
• Installation other than as instructed by these
instructions
WARNING: This gas replace
and vent assembly must be vented
directly to the outside. The venting
system must NEVER be attached
to a chimney serving a separate
solid fuel burning appliance. Each
direct-vent gas appliance must
use a separate vent system. Do not
use common vent systems.
WARNING: Vent pipe air
space clearances to combustibles
are 1" on all sides except on the
horizontal sections, which require
2" clearances from the top of the
pipe. Where the termination cap
penetrates a combustible wall, 1"
air space clearance is required.

www.desatech.com
116646-01D 9
INSTALLATION PLANNING
There are two basic types of direct-vent instal-
lation:
• Horizontal Termination
• Vertical Termination
Horizontal Termination Installation
IMPORTANT: Horizontal square terminations
require only inner portion of wall restop. Hori-
zontal installations using round termination require
exterior portion of wall restop available only in
vent kit HTK (see Figure 14, page 11).
1. Set the replace in its desired location and
determine the route your horizontal venting
will take. Do not secure the replace until
all venting has been installed. Some installa-
tions require sliding the replace in and out
of position to make nal venting connections.
Figures 14 through 18 on pages 11 through 13
show different congurations for venting with
horizontal termination that will help you decide
which application best suits your installation.
Check to see if wall studs or roof rafters are in
the path of your desired venting route. If they
are, you may want to adjust the location of the
replace.
2. Direct vent pipe sections and components are
designed with special twist-lock connections.
Twist-Lock Procedure: The female ends of
the pipes have locking lugs (indentations).
These lugs will slide straight into matching
slots on the male ends of adjacent pipes.
Push pipe sections together and twist one
section clockwise approximately one-quar-
ter turn until the sections are fully locked
(see Figure 8). Note: Horizontal runs of vent
must be supported every three feet. Use wall
straps for this purpose.
3. Use a 45° elbow to connect venting system
to replace ue collar. The elbow is designed
to be twist-locked onto the flue collar as
described in step 2. IMPORTANT: Do not
attempt to alter the conguration of the elbow
by cutting, twisting, bending, etc.
4. Assemble the desired combination of pipe and
elbows to the replace ue collar. If there are
long portions of venting run, pre-assembled
pipe sections may be installed as subassem-
blies for convenience.
VENTING INSTALLATION
INSTRUCTIONS
Continued
5. Carefully determine the location where the vent
pipe assembly will penetrate the outside wall.
The center of the hole should line up with the
center-line of the horizontal vent pipe. Mark the
wall for a 10 3/4" x 10 3/4" square hole. 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, such as masonry block or concrete,
a 8 1/2" hole with zero clearance is acceptable
(see Figure 9).
WARNING: Do not recess
vent termination into any wall.
This will cause a re hazard.

6. Noncombustible Exterior Wall: Position the
horizontal vent cap in the center of the 8 1/2"
round hole and attach to the exterior wall with
four screws (see page 10). Note: The four wood
screws provided should be replaced with ap-
propriate fasteners for stucco, brick, concrete or
other types of sidings. Before attaching the vent
cap to exterior wall, run a bead of non-hardening
mastic (pliable sealant) around the outside edges
to make a seal between it and the outside wall.
Combustible Exterior Wall: For vinyl siding,
stucco or wood exteriors, a siding standoff may
be installed between the vent cap and exterior
wall. The siding standoff prevents excessive
heat from damaging the siding materials. Siding
material must be cut to accommodate stand-
off. Bolt the vent cap to the standoff. Apply
non-hardening mastic around outside edge of
standoff. Position the standoff/cap assembly in
the center of the 10
3
/

" square hole and attach
to exterior wall with wood screws provided (see
Figure 11). The siding standoff must sit ush
against the exterior fascia material.
7. Combustible Exterior Wall Only: Slide the wall
restop over the vent pipe before connecting
horizontal run to vent cap (see Figure 12).
8. Carefully move replace, with vent assembly
attached, toward wall and insert vent pipe
into horizontal termination. The pipe overlap
should be a minimum of 1 1/4" (see Figure 13,
page 11).
9. Combustible Exterior Wall Only: Slide wall
restop against interior wall surface and attach
with screws provided (see Figure 12). See
Figure 13, page 11, for horizontal termination
details.
