Safety Information
WARNING: This product contains and/or generates chemicals
known to the State of California
to cause cancer or birth defects
or other reproductive harm.
IMPORTANT: Read this owner’s
manual carefully and completely
before trying to assemble, operate
or service this fireplace. Improper
use of this fireplace can cause
serious injury or death from
burns, fire, explosion, electrical
shock and carbon monoxide
poisoning.
DANGER: Carbon monoxide
poisoning may lead to death!
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 be working properly.
Get fresh air at once! Have fireplace 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
influence of alcohol and those at high altitudes.
Natural & Propane/LP Gas: Natural & propane/LP
gas 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 fireplace.

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).
• 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.
• Fireplaces with the suffix of -HA have been
designed to operate at altitudes of 4000 feet
and above.

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.

Preparation
Continued
• 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 7.
• 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
(232ºC) 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 13).
• 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.
• For installation of fireplace at elevations of 4000
feet or greater, pay special attention to venting
requirement recommendations.
116200-01F
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 12).
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 12 through 14 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 12).
9. Combustible Exterior Wall Only: Slide wall
firestop against interior wall surface and attach
with screws provided. See Figure 13, page 12,
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.
Roof Flashing
Wall Strap
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" (273
mm x 273 mm) inside dimensions, as shown
in Figure 9 on page 10 using framing lumber
the same size as the ceiling joists. If the area
above the ceiling is an insulated ceiling or
a room, nail firestop from the top side. This
prevents loose insulation from falling into the
required clearance space. Otherwise, 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 10).
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 10.
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 a room or insulated area,
install firestop above framed hole.
45° Elbow
If area above is not a room, 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 15. 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 8. 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.

High Altitude Installation
Your DESA direct-vent fireplace has been tested and
approved for elevations from 0-2000 feet (USA) and
elevations from 0-4500 feet (Canada).
Fireplaces for High Altitude (models ending in
-HA) are for installation above 4000 feet only.
These fireplaces are equipped with parts specific
for higher altitudes. IMPORTANT: These fireplaces can NOT be converted to Propane/LP gas.
When installing a non-high altitude fireplace at an
elevation above 2000 feet (in the USA), you may
need to decrease the input rating by changing the
existing burner orifice to a smaller size. Reduce
input 4% for each 1000 feet above sea level. Check
with your local gas company for proper orifice
size identification.
When installing this fireplace at an elevation
above 4500 feet (in Canada), check with local
authorities.

WARNING: A qualified
service person must connect
fireplace to gas supply. Follow
all local codes.
CAUTION: For propane/LP
units, never connect fireplace directly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install
the external regulator between
the fireplace and propane/LP
supply.
Installation Items Needed
Before installing fireplace, 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 flexible 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 alternative to test gauge connection. Purchase the CSA
design-certified equipment shutoff valve from
your retailer.
For propane/LP connection only, the installer
must supply an external regulator. The external
regulator 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, fireplace regulator damage could occur. Install external regulator with
the vent pointing down as shown in Figure 30,
page 22. Pointing the vent down protects it from
freezing rain or sleet.

CAUTION: Use only new,
black iron or steel pipe. Internally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2" diameter or greater to allow
proper gas volume to fireplace.
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 fireplace (see
Figure 31).
IMPORTANT: Install main gas valve (equipment
shutoff valve) in an accessible location. The main
gas valve is for turning on or shutting off the gas
to the appliance.
Check your building codes for any special requirements for locating equipment shutoff valve
to fireplaces.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could result
in clogged fireplace valves.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.

We recommend that you install a sediment trap/
drip leg in supply line as shown in Figure 31. Locate sediment trap/drip leg where it is within reach
for cleaning. Install in piping system between fuel
supply and fireplace. Locate sediment trap/drip leg
where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This
keeps them from going into fireplace gas controls.
If sediment trap/drip leg is not installed or is installed wrong, fireplace may not run properly.

same time. The fireplace may run for several
minutes before the blower turns on. After the
heater modulates to the pilot position, the blower will continue to run. The blower will shut off
after the firebox temperature decreases.
The blower helps distribute heated air from
the fireplace. Periodically check the louvers of
the firebox and remove any dust, dirt or other
obstructions that will hinder the flow of air.
Inspecting Burners
Check pilot flame pattern and burner flame patterns often.
pilot assembly
The pilot assembly is factory preset for the proper
flame height. Alterations may have occurred during shipping and handling. Call a qualified service
person to readjust the pilot if necessary.
The height of the thermopile must be 3/8" to 1/2"
above the pilot flame as shown in Figure 48. The
thermocouple must be at a height of about 1/8"
above the pilot flame. The flame from the pilot
burner must extend beyond both the thermocouple
and thermopile.
If you pilot assembly does not meet these requirements:
• turn fireplace off (see To Turn Off Gas to Appliance, page 28)
• see Troubleshooting, page 33

BURNER FLAME PATTERN
Burner flames will be steady; not lifting or floating.
Flame patterns will be different from unit to unit
and will vary depending on installation type and
weather conditions.
If the vent configuration is installed incorrectly,
the flames will lift or "ghost". This can be dangerous. Inspect the flames after installation to ensure
proper installation and performance.
Figure 49 shows a typical flame pattern.
If burner flame pattern differs from that described:
• turn fireplace off (see To Turn Off Gas to Appliance, page 28)

Cleaning and
Maintenance
WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep control areas, burners and circulating
air passageways of fireplace clean.
Inspect these areas of fireplace
before each use. Have fireplace
inspected yearly by a qualified
service person. Fireplace may
need more frequent cleaning due
to excessive lint from carpeting,
bedding material, pet hair, etc.
116200-01F
GLASS DOOR
WARNING: Handle glass door
panel with care. Do not strike, slam
or otherwise abuse glass. Do not
operate fireplace with the glass
door unlatched, removed, cracked
or broken.
WARNING: Do not use abrasive cleaners as this may damage
glass. Use a nonabrasive household glass cleaner to clean glass.
Do not clean glass when hot.
Glass must be cleaned periodically. During start-up
it is normal for condensation to form on the inside
of the glass causing lint, dust and other airborne
particles to cling to the glass surface. During initial
start-up a slight film may form on the glass due to
paint curing. The glass should be cleaned several
times with a non-ammonia, nonabrasive household
cleaner and warm water after the first two weeks of
operation. Thereafter, clean the glass two or three
times during each heating season, depending on the
usage and circumstances present. Refer to Removing/Replacing Glass Door, page 25 of this manual
when removing glass door for cleaning.
WARNING: Only parts supplied by the manufacturer should
be used when replacing broken
or damaged glass door panel
(see Replacement Parts, page
37). This glass door panel is
a complete unit. No substitute
materials may be used.
CAUTION: Wear gloves and
safety glasses while handling
or removing broken glass. Do
not remove if glass is hot. Keep
children and pets away from
glass.
If glass has been broken, carefully remove glass
door (see Removing/Replacing Glass Door, page
25). Vacuum all glass pieces with a shop vac.

Continued
CAUTION: Do not vacuum if
pieces are hot.
Use only the tempered glass door replacement
intended for this fireplace (see Replacement Parts,
page 37 for detail on ordering). No substitutions
may be made. See Removing/Replacing Glass
Door, page 25 for instructions for replacing
glass door.
3. Check for evidence of excessive condensation.
Continuous condensation can cause corrosion
of caps, pipes and fittings and can be caused
by having excessive lateral runs, too many
elbows or exterior portions of the system being
exposed to cold weather.
4. Inspect joints to verify that no pipe section or
fitting has been disturbed and loosened. Check
mechanical supports such as wall straps for
rigidity.
WARNING: Do not operate
fireplace with the glass door
unlatched, removed, cracked
or broken.

Warranty Information
KEEP THIS WARRANTY
Model
Serial No.
Date Purchased
Always specify model and serial numbers when communicating with the factory.
We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our
standard written warranty. We make no other warranty, expressed or implied.
LIMITED WARRANTY
DIRECT-VENT FIREPLACE
DESA warrants this product to be free from defects in materials and components for two (2) years from the date
of first purchase, provided that the product has been properly installed, operated and maintained in accordance
with all applicable instructions. To make a claim under this warranty the Bill of Sale or cancelled check must
be presented.
This warranty is extended only to the original retail purchaser. This warranty covers the cost of part(s) required to
restore this heater to proper operating condition and an allowance for labor when provided by a DESA Authorized
Service Center. Warranty part(s) MUST be obtained through authorized retailers of this product and/or DESA who
will provide original factory replacement parts. Failure to use original factory replacement parts voids this warranty.
The heater MUST be installed by a qualified installer in accordance with all local codes and instructions furnished
with the unit.
This warranty does not apply to parts that are not in original condition because of normal wear and tear or parts
that fail or become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by
improper installation. Travel, diagnostic cost, labor, transportation and any and all such other costs related to
repairing a defective heater will be the responsibility of the owner.
TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE
OF THE PRODUCT; THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED
WARRANTIES AND LIMITS THE DURATION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO TWO (2)
YEARS ON ALL COMPONENTS FROM THE DATE OF FIRST PURCHASE; AND DESA’S LIABILITY IS
HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA SHALL NOT BE LIABLE
FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.
Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of
incidental or consequential damages, so the above limitation on implied warranties or exclusion or limitation on
damages may not apply to you.
This warranty gives you specific legal rights and you may also have other rights that vary from state to state.
