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.
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.
WARNING: Any change to
this replace or its controls can
be dangerous.
WARNING: Do not use a blow-
er insert, heat exchanger insert
or other accessory not approved
for use with this replace.
Do not use any solid fuels
(wood, coal, paper, cardboard,
etc.) in this replace. Use only
the gas type indicated on re-
place name plate.
Carefully supervise young chil-
dren when they are in the room
with 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.
• 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.
• The electronic ignition creates spark 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.

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 util-
ity 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.
CLEARANCES
Minimum clearances to combustibles for the
replace are as follows:
*Back and sides 0"
Perpendicular walls 6"
Floor 0"
Ceiling to louver opening 42"
Front 36"
Top 0"
Vent (See venting instructions for
specic venting clearances.)
Combustible material with a maximum thick-
ness of 5/8" may be ush with the top front of
replace.
* For back and sides of replace, do not pack with
insulation or other materials. Zero inch clearance
to combustible materials are for framing purpose
only.

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.
• Install horizontal venting with a 1/4" rise for
every 12" of run toward the termination.
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: Failure to follow these in-
structions will void the warranty.
IMPORTANT: 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
manufactured 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 serv-
ing a separate solid fuel burning
appliance. Each direct-vent gas
appliance must use a separate
vent system. Do not use com-
mon 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
116647-01B 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 (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. Note: The four wood screws
provided should be replaced with appropriate
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
standoff. Bolt the vent cap to the standoff. Ap-
ply non-hardening mastic around outside edge
of standoff. Position the standoff/cap assembly
in the center of the 10

" 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 11/4" (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.

Horizontal Termination Congurations
Figures 14 through 18 show different congura-
tions and alternatives for venting with horizontal
termination. Each gure includes a chart with
critical minimum and maximum dimensions which
MUST be met. IMPORTANT: Remember that a
horizontal run of venting must have a 1/4" rise for
every 12" of run toward the termination.
WARNING: Never run vent
downward as this may cause
excessive temperatures which
could cause a re. Operation of
improperly installed and main-
tained venting system could
result in serious injury, property
damage or loss of life.

INSTALLATION FOR VERTICAL
TERMINATION
Note: Vertical restrictor must be installed in all
vertical installations.
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 19) to avoid cut-
ting load bearing members. 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.
2. Set the replace in desired location. Drop a
plumb line down from the ceiling to the posi-
tion of the replace exit ue. 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 3/4" square hole in the ceiling using
the locating hole as a center point. The opening
should be framed to 10 3/4"x10 3/4" (273 mm
x 273 mm) inside dimensions, as shown in
Figure 9 on page 8 using framing lumber the
same size as the ceiling joists. 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. Otherwise, install restop
below the framed hole. The restop should
be installed with no less than three nails per
side (see Figure 20).
2. Assemble the desired lengths of pipe and
elbows necessary to reach from the replace
ue up through the restop. Be sure all pipe
and elbow connections are fully twist-locked
(see Figure 8, page 9).
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 3/4"x10 3/4" hole must be measured on the
horizontal; actual length may be larger depend-
ing 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 9, page 9.
4. Connect a section of pipe and extend up
through the hole.
Note: If an offset is needed to avoid obstruc-
tions, you must support the vent pipe every 3
feet. Use wall straps for this purpose (see Fig-
ure 19). 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
roong nails. Be sure roong material over-
laps the top edge of the ashing as shown in
Figure 19. 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 7 on
page 7. Note: You must increase vent height
for steep roof pitches. Nearby trees, adjoining
rooines, 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.
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 and meet the
minimum allowable clearances to combustibles.
Do not ll any of the required air spaces with
insulation.

3. Place the blower against the lower rear wall of
the rebox outer wrapper with the exhaust port
directed upward and the thermodisc positioned
up near the replace bottom. The thermodisc
must be oriented near the replace bottom as
shown in Figure 28, in order to sense tempera-
ture and properly operate. The blower will be
held in position against the back wall by the
magnets incorporated onto the blower housing
(see Figure 28).
4. Be certain that all wire terminals are securely at-
tached to terminals on blower motor and thermal
switch and that the screw for the thermodisc
bracket and green ground wire is tight.
5. Mount the speed control box against the
mounting plate provided in the lower replace
cavity by placing the plastic control shaft
forward through the round hole (see Figure
26, page 18).
6. While supporting speed control, secure control
shaft with lock nut by pushing and turning
lock nut with pliers clockwise until it is tight
against mounting plate. Place control knob
provided on shaft (see Figure 26, page 18).
7. Check to make sure that the power cord is com-
pletely clear of the blower wheel and that there
are no other foreign objects in blower wheel.
Also double check all wire leads and make sure
wire routing is not pinched or in a precarious
position. Correct accordingly.
8. Turn on power to duplex outlet if previ-
ously turned off per the warning in column
2, page 17.
9. Plug in blower power cord to duplex outlet.
10. The blower will only run when the speed control
knob is in the ON position and the thermal switch
senses temperature after the replace begins to
heat up. The blower speed can be adjusted by
rotating the control knob. To turn off, turn knob
fully counterclockwise until it clicks off. If the
blower is ON and has been running with the
replace operating, the blower will continue to
run for a short time after the replace has been
turned off. As the thermal switch cools down,
the blower shuts down automatically.
11. Peel off the backing paper and stick the sup-
plied wiring diagram decal on the rebox bot-
tom approximately 12" in front of the blower
(see Figure 27, page 18).

INSTALLING GAS PIPING TO
FIREPLACE LOCATION
WARNING: A qualified
service person must connect
replace to gas supply. Follow
all local codes.
CAUTION: For propane/LP
units, never connect replace di-
rectly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install
the external regulator between
the replace and propane/LP
supply.
Installation Items Needed
Before installing replace, make sure you have the
items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved exible gas line with gas connector
(if allowed by local codes)
* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable alterna-
tive to test gauge connection. Purchase the CSA
design-certied equipment shutoff valve from
your retailer.
For propane/LP connection only, the installer must
supply an external regulator. The external regula-
tor will reduce incoming gas pressure. You must
reduce incoming gas pressure to between 11 and 14
inches of water. If you do not reduce incoming gas
pressure, replace regulator damage could occur.
Install external regulator with the vent pointing
down as shown in Figure 30. Pointing the vent
down protects it from freezing rain or sleet.

CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2" inside diameter or greater to
allow proper gas volume to re-
place. If pipe is too small, undue
loss of volume will occur.
Installation must include an equipment shutoff
valve, union and plugged 1/8" NPT tap. Locate NPT
tap within reach for test gauge hook up. NPT tap
must be upstream from replace (see Figure 31).
