This fireplace must be installed by a qualified (certified 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 flu, with headaches, dizziness, or nausea. If
you have these signs, the fireplace may not have been installed
properly. Get fresh air at once! Have fireplace inspected and
serviced by a qualified 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
influence of alcohol, and those at high altitudes.

Location and Space Requirements
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 does not require electricity to operate.
• Only the blower requires electricity if installed and if you plan
to install the blower at a later date, do not forget to wire the
outlet at the bottom of the fireplace when framing.
• A piezo ignitor and ceramic electrode create 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 fireplace, you may notice some
amount of condensation on the inside of the fireplace glass. This
is normal and will disappear after 10-20 minutes of operation.
• 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
• 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 6.
• 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 (232ºC) heatresistant 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.
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.

Termination Clearances for Buildings with Combustible and Noncombustible Exteriors
NOTICE: Read these instructions completely before attempting installation.
These models are tested and approved for use with DESA (directvent) 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 must 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.
• V ent 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.
• Install horizontal venting with a 1/4" rise for every 12" of run
toward the termination.
NOTICE: Failure to follow these instructions will void
the warranty.
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.
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.
IMPORTANT:

INSTALLATION PLANNING
There are two basic types of direct-vent installation:
• Horizontal T ermination
• Vertical Termination
Horizontal Termination Installation
IMPORTANT:
portion of wall firestop. Horizontal installations using round termination require exterior portion of wall firestop.
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).
ported 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.
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).
Horizontal square terminations require only inner

provided should be replaced with appropriate fasteners for
stucco, brick, concrete, or other types of sidings.
Combustible Exterior W all: 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 standof f must sit
flush against the exterior fascia material.
7.Combustible Exterior W all O nly: 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".
