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, con-
nected, and sealed, carbon monoxide leakage
(spillage) can occur.
Early signs of
carbon monoxide poisoning resemble the u,
with headaches, dizziness, or nausea. If you
have these signs, the replace may not have
been installed properly. Get fresh air at once!
Have replace inspected and serviced by a
qualied service person. 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 inu-
ence of alcohol, and those at high altitudes.
Propane/
LP and natural 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.

IDENTIFICATION
PRODUCT FEATURES
These are a few facts that can help you under-
stand 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.

• This replace does not require electricity
to operate.
• Only the blower requires electricity if in-
stalled and if you plan to install the blower
at a later date, do not forget to wire the
outlet at the bottom of the replace when
framing.
• A piezo ignitor and ceramic electrode cre-
ate 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 fireplace system
(replace and venting) is a balanced and
sealed gas operating unit. It requires ap-
proximately 10-20 minutes of operating
time before the ame pattern stabilizes.
PRE-INSTALLATION
PREPARATION
LOCATION AND SPACE
REqUIREMENTS
Determine the safest and most efcient loca-
tion for your DESA Heating, LLC 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 com-
mon 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 ma-
terial 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 impor-
tant 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 (232º C) 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 exces-
sive 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.

INSTALLATION PRECAUTIONS
• Wear gloves and safety glasses for pro-
tection
• 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 com-
ponent
• Unauthorized modication of the venting
system (Do not cut or alter vent compo-
nents)
• Installation of any component part not
manufactured or approved by DESA Heat-
ing, LLC.
• Installation other than as instructed by
these instructions
-
-
-
on the horizontal sections,
NOTICE: Read these instruc-
-
These models are tested and approved for
use with DESA Heating, LLC (direct-vent) pipe
components and terminations.
The venting system must terminate on the
outside of the structure and can not be at-
tached 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 horizon-
tally 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 com-
bustibles are 1" on all sides except on the
horizontal sections, which requires 2" clear-
ance 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 compo-
nents on hand to help determine the exact
measurements when elbowing or offsetting.
Always use wall restops when penetrating
walls and restops when penetrating ceil-
ings or attic spaces.
• If using a venting conguration of only
horizontal venting with no vertical run, a
1/4" rise for every 12" of run toward the
termination is required.
WARNING: Read all instruc-
Failure to do so could result in

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 termina-
tion require exterior portion of wall restop
available only in vent kit HTK (see Figure
14, page 11).
1. Set replace in its desired location and de-
termine the route your horizontal venting
will take. Do not secure replace until all
venting has been installed. Some instal-
lations require sliding replace in and out
of position to make nal venting connec-
tions. Figures 14 through 18 on pages 10
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 location of replace.
2. Direct vent pipe sections and components
are designed with special twist-lock con-
nections.
Twist-Lock Procedure: Female ends of
pipes have locking lugs (indentations).
These lugs will slide straight into match-
ing slots on male ends of adjacent pipes.
Push pipe sections together and twist
one section clockwise approximately one-
quarter turn until 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 sys-
tem to replace ue collar. The elbow is
designed to be twist-locked onto the ue
collar as described in step 2.
IMPORTANT: Do not attempt to alter
conguration of elbow by cutting, twisting,
bending, etc.
4. Assemble desired combination of pipe
and elbows to replace ue collar. If there
are long portions of venting run, pre-
assembled pipe sections may be installed
as subassemblies for convenience.

5. Carefully determine the location where
vent pipe assembly will penetrate outside
wall. The center of hole should line up with
center line of horizontal vent pipe. Mark
wall for a 10" x 10" square hole. Cut and
frame square hole in exterior wall where
vent will be terminated. If wall being pen-
etrated is constructed of noncombustible
material, such as masonry block or con-
crete, a 7 3/4" hole with zero clearance is
acceptable (see Figure 9).

VENTING INSTALLATION
Continued
WARNING: Do not recess
6. Posi-
tion horizontal vent cap in the center of 7
3/4" round hole and attach to exterior wall
with four wood screws provided. Before
attaching vent cap to exterior wall, run a
bead of non-hardening mastic (pliable
sealant) around outside edges to make a
seal between it and outside wall.
Note: The four wood screws provided
should be replaced with appropriate fas-
teners for stucco, brick, concrete or other
types of sidings.
For vinyl
siding, stucco or wood exteriors, a siding
standoff may be installed between vent
cap and exterior wall. The siding standoff
prevents excessive heat from damaging
siding materials. Siding material must be
cut to accommodate standoff. Bolt vent
cap to standoff. Apply non-hardening
mastic around outside edge of standoff.
Position standoff/cap assembly in the
center of the 10" square hole and attach
to exterior wall with wood screws provided
(see Figure 11). Siding standoff must sit
ush against exterior fascia material.
7. Slide
wall restop over vent pipe before con-
necting horizontal run to vent cap (see
Figure 12).
8. Carefully move replace, with vent as-
sembly attached, toward wall and insert
vent pipe into horizontal termination. Pipe
overlap should be a minimum of 1 1/4" (see
Figure 13, page 11).
9. Slide
wall restop against interior wall surface
and attach with screws provided. See Fig-
ure 13, page 11, for horizontal termination
details.
10. Place replace into position and shim with
noncombustible material if needed. Nail or
screw side anges to framing to secure
unit in place. IMPORTANT: Make sure re-
place is level before securing. If replace
is not level it will not work properly.

system, consider an offset (see Figure 19)
to avoid cutting load bearing members.
Note: Pay special attention to these instal-
lation 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 verti-
cal 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
position 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.
1.
Cut a 10" square hole in the ceiling using
the locating hole as a center point. The
opening should be framed to 10" x 10"
inside dimensions, as shown in Figure 9
on page 9 using framing lumber the same
size as the ceiling joists. If the area above
the ceiling is an insulated ceiling or attic
space, nail restop from the top side. This
prevents loose insulation from falling into
the required clearance space. If the area
above the ceiling is a living space, 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" x 10" 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 9, page 9.
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 19, page 14). When-
ever 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 fram-
ing with roong nails. Be sure roong
material overlaps the top edge of the
ashing as shown in Figure 19, page 14.
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

the vent height may solve this problem.
7. Twist-lock the vent cap onto the last sec-
tion of vent pipe.
Note: If the vent pipe passes through any oc-
cupied areas above the rst oor, including

pipe. You may frame and sheetrock the en-
closure 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.

INSTALLING GAS PIPING TO
FIREPLACE LOCATION
WARNING: For natural
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 connec-
tor (if allowed by local codes)
* A CSA design-certied equipment shutoff
valve with 1/8" NPT tap is an acceptable alter-
native to test gauge connection. Purchase the
CSA design-certied equipment shutoff valve
from your retailer.
For propane/LP connection only, the installer
must supply an external regulator. The ex-
ternal regulator will reduce incoming gas
pressure. You must reduce incoming gas
pressure to between 11" and 14" 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,
