SAFETY INFORMATION
Continued
DANGER: Carbon monoxide
poisoning may lead to death!
This replace must be installed by a qualied (certied 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 combustion 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 headaches, 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
inuence 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.

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 outside 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 replace 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 inside 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 operating unit. It requires approximately 10-20
minutes of operating time before the ame
pattern stabilizes.

PREPARATION
LOCATION AND SPACE
REqUIREMENTS
Determine the safest and most efcient 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 chimney ue serving a separate solid-fuel burning
replace or appliance.
• Due to high temperatures, do not locate this
replace in high trafc 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 material 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 surface 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 entertainment 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.
CLEARANCES
Minimum clearances to combustibles for the
replace are as follows:
*Back and sides 0"

VENTING INSTALLATION
INSTRUCTIONS
NOTICE: Read these instructions completely before attempting 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 following 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 instructions 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:
•
In s t all a t ion of any da m a ged ven t i ng
component
• Unauthorizedmodicationoftheventingsystem (Do not cut or alter vent components)
• Instal lation 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 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.

INSTALLATION PLANNING
There are two basic types of direct-vent installation:
• Horizontal Termination
• Vertical Termination
Horizontal Termination Installation
IMPORTANT: Horizontal square terminations
require only inner portion of wall restop. Horizontal 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 installations 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 congurations 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-quarter 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 conguration 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 subassemblies for convenience.
116647-01B 9
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. No te: 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 mate rials.
Siding material must be cut to accommodate
standoff. 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 3/4" 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.
