Product Features
These are a few facts that can help you understand
and enjoy your direct-vent fireplace:
• 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 fireplace may be installed in any room of
your house provided all local codes and these
installation instructions are followed.
• This fireplace requires a wall switch, hand-held
remote or wall thermostat (millivolt) for operation (see Accessories, page 42).
• The use of a blower requires electricity if
installed. If you plan to install the blower at a
later date, outlet at bottom of fireplace must be
wired during framing.
• Your direct-vent gas fireplace system (fireplace
and venting) is a balanced and sealed gas operating unit. It requires approximately 10-20
minutes of operating time before the flame
pattern stabilizes.

Pre-Installation
Preparation
Location and space
requirements
Determine the safest and most efficient location
for your DESA direct-vent fireplace. 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 fireplace and termination cap.
When deciding the location of your fireplace,
follow these rules:
• Do not connect this fireplace venting to a chimney flue serving a separate solid-fuel burning
fireplace or appliance.
• Due to high temperatures, do not locate this
fireplace in high traffic areas, windy or drafty
areas or near furniture or draperies.
• Proper clearances must be maintained.
• If your fireplace 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 fireplace. See Figure 3.
• Your fireplace 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 fireplace,
except where standoff spacers are integrally
attached. If standoff spacers are attached to your
fireplace, these spacers can be placed directly
against wall or framing material. See framing
details on page 5.
• If you plan on installing a television or entertainment center recessed above your fireplace, 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 8.
• If recessing into a wall, you can avoid extra
framing by positioning your fireplace against
an already existing framing member.
• Do not recess termination cap into a wall or
siding.
• You may paint the termination cap with 450ºF
heat-resistant paint to coordinate with the exterior finish.
• 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.

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 flue 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 finish such as vinyl, wood,
stucco, etc.
• Never run the vent downward as this may
cause excessive temperatures which could
cause a fire.
• 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 11).
• Have fireplace and selected vent components on
hand to help determine the exact measurements
when elbowing or offsetting. Always use wall
firestops when penetrating walls and firestops
when penetrating ceilings or attic spaces.
• If using a venting configuration of only horizontal venting with no vertical run, a 1/4" rise
for every 12" of run toward the termination is
required.
• For installation of fireplace at elevations of 4000
feet or greater, pay special attention to venting
requirement recommendations.
118197-01C
WARNING: Read all instructions 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.
NOTICE: Do not seal termination
cap to vent pipe. Cap must be
removable for vent inspection
and maintenance.
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 modification of the venting system (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 fireplace
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 firestop. Horizontal installations using round termination require
exterior portion of wall firestop (see Figure 14,
page 10.
1. Set the fireplace in its desired location and determine the route your horizontal venting will take.
Do not secure the fireplace until all venting has
been installed. Some installations require sliding
the fireplace in and out of position to make final
venting connections. Figures 14 through 18 on
pages 10 through 12 show different configurations 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 fireplace.
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 fireplace flue 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 configuration of the elbow
by cutting, twisting, bending, etc.
4. Assemble the desired combination of pipe and
elbows to the fireplace flue 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 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).

Vent Cap
WARNING: Do not recess
vent termination into any wall.
This will cause a fire 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 wood screws provided. 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. Note: The four wood screws
provided should be replaced with appropriate
fasteners for stucco, brick, concrete or other
types of sidings.
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. 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 flush
against the exterior fascia material.
7. Combustible Exterior Wall Only: Slide the wall
firestop over the vent pipe before connecting
horizontal run to vent cap (see Figure 12).
8. Carefully move fireplace, 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 10).
9. Combustible Exterior Wall Only: Slide wall
firestop against interior wall surface and attach
with screws provided. See Figure 13, page 10,
for horizontal termination details.
10. Place fireplace into position and shim with
noncombustible material if needed. Nail or
screw side flanges to framing to secure unit in
place. IMPORTANT: Make sure fireplace is
level before securing. If fireplace is not level
it will not work properly.

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 cutting 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 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.

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" x 10 3/4" (27.3 cm x
27.3 cm) 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 an attic space,
nail firestop 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 firestop below the framed
hole. The firestop 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 fireplace
flue up through the firestop. Be sure all pipe
and elbow connections are fully twist-locked
(see Figure 8, page 8).
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" x 10 3/4" 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 8.
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). Whenever possible, use 45° elbows
instead of 90° elbows. The 45° elbow offers
less restriction to the flow of the flue gases
and intake air.
If area above is an attic space or insulated
area, install firestop above framed hole.
45° Elbow
If area above is a living space, install
firestop below framed hole.

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 19,
page 13. 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 6. 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.
Note: If the vent pipe passes through any occupied
areas above the first floor, 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 fill any of the required air spaces with
insulation.
