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,
explosions, 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 have been installed
properly. Get fresh air at once! Have fireplace inspected and ser-
viced 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.

Propane/LP and Natural Gas: 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 fireplace.

WARNING: Any change to this fireplace or its

controls can be dangerous.

1. This appliance is only for use with the type of gas indicated on
the rating plate. This appliance is not convertible for use with
other gases unless a certified kit is used.

2. For propane/LP fireplace, do not place propane/LP supply
tank(s) inside any structure. Locate propane/LP supply tank(s)
outdoors. To prevent performance problems, do not use pro­pane/LP fuel tank of less than 100 lbs. capacity.

3. If you smell gas

• shut off gas supply

• do not try to light any appliance

• do not touch any electrical switch; do not use any phone in

your building

• immediately call your gas supplier from a neighborʼs phone.

Follow the gas supplier's instructions

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.

• The blower requires electricity if installed. 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.

• 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 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 10­20 minutes of operating time before the flame pattern stabilizes.

• 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.

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.

VENTING INSTALLATION
INSTRUCTIONS

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 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.

• Install horizontal venting with a 1/4" rise for every 12" of run
toward the termination.

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.

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:

• 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 com
bustible 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

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
zero clearance is acceptable (see Figure 9).

WARNING: Do not recess vent termination into

any wall. This will cause a fire hazard.

exterior wall with four screws. Note: The four wood screws
provided should be replaced with appropriate fasteners for
stucco, brick, concrete or other types of sidings. Before attach
ing 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 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

3

the 10

/4" square hole and attach to exterior wall with wood
screws provided (see Figure 11, page 9). The siding standoff
must sit flush against the exterior fascia material.

SNORKEL TERMINATION INSTALLATION

Recommended Applications:

• Installations requiring a vertical rise on building exterior

• Any installation using snorkel termination to achieve one foot above ground

Snorkel terminations are available for installations requiring a vertical rise on the exterior of the building. If installing snorkel termina­tion below grade, you must provide proper drainage to prevent water from entering snorkel termination (see Figure 16). Do not back fill
around snorkel termination.

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
(273 mm x 273 mm) 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 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 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"x10 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 sup-

port the vent pipe every 3 feet. Use wall straps for this purpose
(see Figure 19, page 12). 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.

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 12. 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.

/4"x10 3/4"

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.

FIREPLACE INSTALLATION

CHECK GAS TYPE

Use proper gas type for the fireplace unit you are installing. If your
gas supply is not correct, do not install fireplace. See retailer where
you purchased the fireplace for proper fireplace according to your gas
type or to purchase gas conversion kit (see Accessories, page 34).

INSTALLING OPTIONAL BLOWER
ACCESSORY

NOTICE: If installing blower in an existing fireplace
with gas connections, shut off gas supply and dis­connect heater from gas supply. Contact a qualified
service person to do this.

WARNING: If there is a duplex electrical outlet
installed in the right side of the bottom of the fireplace
base area, be sure that the electrical power to the outlet
is turned off before proceeding with blower installation.
Failure to do this may result in serious injury.

Model BK Installation

Follow all instructions provided in the blower accessory kit.

1. Attach the power cord to the blower motor by firmly pushing the
two female terminals at the end of the power cord onto the two
spade terminals on the blower motor (see Figure 25).

2. Attach green ground wire from power cord to blower hous
ing using screw provided (see Figure 25). Tighten screws
securely.

3. Place the blower against the lower rear wall of the firebox outer
wrapper with the exhaust port directed upward. The blower will
fit inside the back opening and be held in position against the
back wall by the magnets (see Figure 25).

4. Be certain that all wire terminals are securely attached to ter
minals on blower motor and that the screw retaining the green
ground wire is tight.

7. Turn on power to duplex outlet if previously turned off per the
warning in column 1.

8. Plug in blower power cord.
a. If your firebox is installed as a freestanding unit with an

accessory mantel, determine whether the power cord will
exit the left side or the right side of the firebox. Route power
cord through exit hole and plug the power cord into a wall
receptacle near the firebox.

b. If your firebox installation is recessed and/or pre-wired,

plug the power cord into the duplex outlet provided. Refer
to your firebox ownerʼs manual for instructions on wiring
the duplex outlet.

CAUTION: Never touch the blower wheel while

in operation.

9. Check to make sure that the power cord is completely clear of the
blower wheel and that there are no other foreign objects in blower
wheel. Turn blower on and check for operation. Turn blower off

Model BKT Installation

Note: When installing the BKT thermostatically-controlled blower,
you must first secure the thermal switch bracket to the blower if it
has not already been factory installed.

1. Place the green ground wire with ring terminal between the
bottom hole on the thermal switch bracket and the top ear hole
on the blower assembly. Insert the phillips screw into all three
pieces and tighten securely (see Figure 28).

2. Connect wire harness and power cord terminals. Connect the
blue jumper wire to the blower motor terminal and the right
side terminal of the thermal switch. Connect the black wire to
the left side of the thermal switch and the white wire to the
other remaining blower motor terminal.

Note: The power cord outer insulation sleeve may have to be
stripped slightly to allow enough wire length to reach and make
all connections. DO NOT trim excessive length away. Just enable
enough to make all connections securely.

3. Place the blower against the lower rear wall of the firebox outer
wrapper with the exhaust port directed upward and the thermo­disc positioned up near the fireplace bottom. The thermodisc
must be oriented near the fireplace bottom as shown in Figure 28,
in order to sense temperature and properly operate. The blower
will be held in position against the back wall by the magnets
incorporated onto the blower housing (see Figure 28).

4. Be certain that all wire terminals are securely attached to ter­minals on blower motor and thermal switch and that the screw
for the thermodisc bracket and green ground wire is tight.

forward through the round hole (see Figure 26, page 16).

6. While supporting speed control, secure control shaft with lock
nut by pushing and turning lock nut with pliers clockwise until
it is tight against mounting plate. Place control knob provided
on shaft (see Figure 26, page 16).

7. Check to make sure that the power cord is completely clear of the
blower wheel and that there are no other foreign objects in blower
wheel. Also double check all wire leads and make sure wire routing
is not pinched or in a precarious position. Correct accordingly.

8. Turn on power to duplex outlet if previously turned off per the
warning in column 1, page 16.

9. Plug in blower power cord to duplex outlet.

10. The blower will only run when the speed control knob is in the
ON position and the thermal switch senses temperature after the
fireplace begins to heat up. The blower speed can be adjusted by
rotating the control knob. To turn off, turn knob fully counterclock­wise until it clicks off. If the blower is ON and has been running
with the fireplace operating, the blower will continue to run for a
short time after the fireplace has been turned off. As the thermal
switch cools down, the blower shuts down automatically.

11. Peel off the backing paper and stick the supplied wiring diagram
decal on the firebox bottom approximately 12" in front of the
blower (see Figure 27, page 16).

Installing Gas Piping to Fireplace Location

FIREPLACE INSTALLATION

Continued

INSTALLING GAS PIPING TO FIREPLACE
LOCATION

WARNING: A qualified service person must con-

nect 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. Pointing the
vent down protects it from freezing rain or sleet.

External
Regulator

Propane/LP
Supply Tank

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" inside 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 con
trols. If sediment trap/drip leg is not installed or is installed wrong,
fireplace may not run properly.

INSPECTING BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT ASSEMBLY

The pilot assembly is factory preset for the proper flame. Altera­tions may have occurred during shipping and handling. The pilot
is located on the left hand side of the burner.

The flame must envelope 1/4" of top of the ignitor/sensor and
grounding stem.

If your pilot assembly does not meet these requirements:

• Turn the adjustment screw marked PILOT clockwise to decrease
or counterclockwise to increase the flame to proper size (see
Figure 48, page 24). Do not remove the adjustment screw.

• see Troubleshooting

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.

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.

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 instal
lation 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 51 shows a typical flame pattern.

If burner flame pattern differs from that described:

• turn fireplace off (see To Turn Off Gas to Appliance, page 24)

• see Troubleshooting, page 27

Figure 51 - Typical Flame Pattern

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 on page
20 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 29). 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 20). Vacuum all glass pieces with

a shop vac.

CAUTION: Do not vacuum if pieces are hot.

No substitutions may be made. See Removing/Replacing Glass
Door, page 20 for instructions for replacing glass door.

WARNING: Do not operate fireplace with the glass

door unlatched, removed, cracked or broken.

PILOT AND BURNERS

• Remove ember material before cleaning burners and replace
when cleaning is complete.

• Burner and controls should be cleaned with compressed air to
remove dust, dirt or lint.

• Use a vacuum cleaner or small, soft bristled brush to remove
excess dust, dirt or lint.

LOGS

• If you remove logs for cleaning, refer to Installing Logs, Lava
Rock and Glowing Embers, page 21, to properly replace logs.

• Use a vacuum cleaner to remove any carbon buildup on logs.

• Replace log(s) if broken. See Replacement Parts on page 29.

• Replace ember material periodically as needed. See Replacement
Parts on page 29.

VENTING SYSTEM

Conduct annual inspection of the venting system following these
guidelines:

1. Check areas of venting system that are exposed to the weather for
corrosion (rust spots or streaks and, in extreme cases, holes). Have
these items replaced immediately by a qualified service person.

2. Remove the vent cap and shine a flashlight into the vent. Re
move any foreign material.

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.

WARRANTY INFORMATION

116647 01

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 DESAʼS 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.
