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.
Propane/LP & Natural Gas: Propane/LP and
natural 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 CD36R dedicated rear vent is best suited
for flush or corner installations when vented
horizontally through an exterior wall.
• The CD36T dedicated top vent is suited for
any application where height is necessary to
terminate the venting system either through
the roof (vertical) or to gain sufficient height
and offset to vent to an outside/exterior wall
(horizontal).
• The vent pipe installation is very important to
allow for proper operation. You must select
the appropriate unit for your application and
follow the venting instructions to plan your
installation.
• This fireplace may be installed in any room of
your house provided all local codes and these
installation instructions are followed.
• Models (V)CD36R/T are equipped with a millivolt gas control system that does not require
electricity to operate. A piezo ignitor is provided to
light the pilot without using matches or lighters.
• Models (V)CD36RE/TE are equipped with an
electronic ignition system that requires 120VAC
to operate. An electrode ignitor automatically lights the pilot flame when the fireplace
is turned on.
• All models can accept an optional circulating
air blower when 120 VAC connection is supplied. If you plan to install an optional blower,
do not forget to wire the fireplace outlet when
framing.
• 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.
116035-01E
• Your direct-vent gas fireplace system (fireplace
and venting) is a balanced and sealed gas operating unit. It is highly efficient because it uses
outside air for combustion while independently
heating the indoor air.
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, page 6.
• 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:
• 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.
• 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.
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.
IMPORTANT: Do not seal vent cap to pipe. Cap
must be removable for servicing.

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 20,
page 14).
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 18 through 25 on
pages 13 through 16 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 11). Note: Horizontal runs of vent must be supported every three
feet. Use wall straps for this purpose.
3. Any straight pipe section, a 45° or 90° elbow
can be used when first connecting the venting
system to the fireplace. Elbows are designed
to twist-lock into any of four 90° positions to
direct the venting system to the desired location. 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 12).

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 (see Figure 13).
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 14).
The siding standoff must sit flush against the
exterior fascia material.
7. Combustible Exterior Wall Only: Fit the outer
and inner wall firestop into the wall before
connecting horizontal run to vent cap (see
Figure 15).
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".
9. Combustible Exterior Wall Only: Slide wall
firestop against interior wall surface and attach
with screws provided (see Figure 16, page
13). See Figure 17, page 13, 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.
NOTICE: Do not seal termination
cap to vent pipe. Cap must be
removable for vent inspection
and maintenance.

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 26) 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" (273 mm x
273 mm) inside dimensions, as shown in Figure
12 on page 11 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 27).
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 11, 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 12, page 11.
If area above is a room or insulated area,
install firestop above framed hole.
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 26, page 16). 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 26,
page 16. 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 10 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.
If area above is not a room, install firestop
below framed hole.

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 39 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 39).
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.
5. Mount speed control box by placing plastic
control shaft through opening in switch
bracket (see Figure 36, page 22) or ignition
module bracket (see Figure 37, page 22).
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 36 or 37, page 22).
7. Check to make sure that power cord is completely clear of 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 warning in column 2, page 21.
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.

High Altitude installation
Your DESA direct-vent fireplace has been tested
and approved in the USA for elevations from
0-2000 feet (610 m) and in Canada at elevations
from 0-4500 feet (1372 m).
High-altitude models as indicated by the letter suffix (-HA) are equipped with specific gas controls
for installation above 4000 feet.
IMPORTANT: Fireplaces when factory equipped
for use at highaltitude can not be converted for use with Propane/LP gas. When installing a non-high altitude
fireplace at an elevation above 2000 feet (610 m)
(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 (305 m) above sea level. Check with your
local gas company for proper derate procedure
and orifice size.
When installing this fireplace in Canada at an
elevation above 4500 feet (1372 m), Check with
local or provincial code authorities.
Consult your local gas company to help determine
the proper orifice for your location.
For assistance with any high altitude installation
contact DESA’s Customer Service Department at
1-866-672-6040.
26
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 45).
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 49, page 27. 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 50).
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.

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.

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 position and pattern of the pilot flames in relation to the sensing devices should be as shown in
Figures 66 and 67 depending on model.
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 68 shows a typical flame pattern.
If burner flame pattern differs from that described:
• turn fireplace off (see To Turn Off Gas to Appliance, page 32 or 35 depending on model)

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.
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 29 of this manual
when removing glass door for cleaning.
116035-01E
WARNING: Only parts supplied by the manufacturer should
be used when replacing broken
or damaged glass door panel
(see Replacement Parts, page
44). 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
29). Vacuum all glass pieces with a shop vac.
CAUTION: Do not vacuum if
pieces are hot.
Use only the tempered glass door replacement
intended for this fireplace (see Replacement Parts,
page 44 for detail on ordering). No substitutions
may be made. See Removing/Replacing Glass
Door, page 29 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
30, 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 44.
• Replace ember material periodically as needed.
See Replacement Parts on page 44.
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. Remove 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
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.
