PRODUCT FEATURES

These are a few facts that can help you understand
and enjoy your direct-vent replace:

• 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 replace may be installed in any room of
your house provided all local codes and these
installation instructions are followed.

• This replace does not require electricity to
operate.

• Only the blower requires electricity if installed.
If you plan to install the blower at a later date,
outlet must be wired at the bottom of the re­place when framing.

• A piezo ignitor and ceramic electrode create
sparks 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 replace, you may
notice some amount of condensation on the in­side of the replace glass. This is normal and will
disappear after 10-20 minutes of operation.

• Your direct-vent gas replace system (replace
and venting) is a balanced and sealed gas op­erating unit. It requires approximately 10-20
minutes of operating time before the ame
pattern stabilizes.

• Fireplaces with the sufx of -HA have been
designed to operate at altitudes of 4000 feet
and above.

PREPARATION

LOCATION AND SPACE
REQUIREMENTS

Determine the safest and most efcient location
for your DESA direct-vent replace. 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 replace and termination cap.

When deciding the location of your replace,
follow these rules:

• Do not connect this replace venting to a chim­ney ue serving a separate solid-fuel burning
replace or appliance.

• Due to high temperatures, do not locate this
replace in high trafc areas, windy or drafty
areas or near furniture or draperies.

• Proper clearances must be maintained.

• If your replace 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 replace. See Figure 3.

• Your replace 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 replace,
except where standoff spacers are integrally
attached. If standoff spacers are attached to your
replace, these spacers can be placed directly
against wall or framing material. See framing
details on page 6.

• If you plan on installing a television or enter­tainment center recessed above your replace, 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 7.

• If recessing into a wall, you can avoid extra
framing by positioning your replace against
an already existing framing member.

• Do not recess termination cap into a wall or
siding.

•

You may paint the termination cap with 450º F
heat-resistant paint to coordinate with the exterior
nish.

116646-01D 5

www.desatech.com

• 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.

• For horizontal installations above 2,000 feet, it
is recommended that a 12" extension pipe be
added before starter elbow and a round hori­zontal termination be used (see High Altitude
Installation, page 16).

VENTING INSTALLATION

INSTRUCTIONS

NOTICE: Read these instruc-

tions 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 ue 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 nish such as vinyl, wood,
stucco, etc.

• Never run the vent downward as this may
cause excessive temperatures which could
cause a re.

• 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.

• Sn orkel term ina tio ns are re qui red whe n
minimum clearance to grade cannot be met (see
Figure 16 on page 12).

• Have replace and selected vent components on
hand to help determine the exact measurements
when elbowing or offsetting. Always use wall
restops when penetrating walls and restops
when penetrating ceilings or attic spaces.

• If using a venting conguration of only hori­zontal venting with no vertical run, a 1/4" rise
for every 12" of run toward the termination is
required.

• For installation of replace at elevations of 4000
feet or greater, pay special attention to venting
requirement recommendations.

WARNING: Read all instruc-

tions 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 in-

structions will void the warranty.

NOTICE: 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 modication 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 replace
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 restop. Hori­zontal installations using round termination require
exterior portion of wall restop available only in
vent kit HTK (see Figure 14, page 11).

1. Set the replace in its desired location and
determine the route your horizontal venting
will take. Do not secure the replace until
all venting has been installed. Some installa­tions require sliding the replace in and out
of position to make nal venting connections.
Figures 14 through 18 on pages 11 through 13
show different congurations 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
replace.

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 replace ue 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 conguration of the elbow
by cutting, twisting, bending, etc.

4. Assemble the desired combination of pipe and
elbows to the replace ue collar. If there are
long portions of venting run, pre-assembled
pipe sections may be installed as subassem­blies for convenience.

116646-01D 9

INSTRUCTIONS

Continued

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).

WARNING: Do not recess

vent termination into any wall.
This will cause a re 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 screws (see page 10). Note: The four wood
screws provided should be replaced with ap­propriate fasteners for stucco, brick, concrete or
other types of sidings. 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.

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 ush
against the exterior fascia material.

7. Combustible Exterior Wall Only: Slide the wall
restop over the vent pipe before connecting
horizontal run to vent cap (see Figure 12).

8. Carefully move replace, with vent assembly
attached, toward wall and insert vent pipe
into horizontal termination. The pipe overlap
should be a minimum of 1 1/4" (see Figure 13,
page 11).

9. Combustible Exterior Wall Only: Slide wall
restop against interior wall surface and attach
with screws provided (see Figure 12). See
Figure 13, page 11, for horizontal termination
details.

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 replace in desired location. Drop a

plumb line down from the ceiling to the posi­tion of the replace exit ue. 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" inside
dimensions, as shown in Figure 9 on page 9
using framing lumber the same size as the
ceiling joists. If the area above the ceiling is
an insulated ceiling or an attic, nail restop
from the top side. This prevents loose insula­tion from falling into the required clearance
space. If the area above the ceiling is a living
space, install restop below the framed hole.
The restop 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 replace
ue up through the restop. Be sure all pipe
and elbow connections are fully twist-locked
(see Figure 8, page 9).

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 9.

4. Connect a section of pipe and extend up
through the hole.

Note: If an offset is needed to avoid obstruc-

tions, 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 ow of the ue gases
and intake air.

5. Place the ashing over the pipe section(s)
extending through the roof. Secure the base
of the ashing to the roof and framing with
roong nails. Be sure roong material over­laps the top edge of the ashing as shown in
Figure 19. There must be a 1" clearance from
the vent pipe to combustible materials.

If area above is an
attic or insulated

area, install restop

above framed hole.

If area above is a
living space, install

restop below framed

hole.

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
rooines, 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 rst oor, 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 ll any of the required air spaces with
insulation.

HIGH ALTITUDE INSTALLATION

Your DESA direct-vent replace 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 replaces are equipped with parts specic
for higher altitudes. IMPORTANT: These replac-
es can NOT be converted to Propane/LP gas.

When installing a non-high altitude replace at an
elevation above 2000 feet (in the USA), you may need
to decrease the input rating by changing the existing
burner orice to a smaller size. Reduce input 4% for
each 1000 feet above sea level. Check with your local
gas company for proper orice size identication.

INSTALLING GAS PIPING TO
FIREPLACE LOCATION

WA R NING: A q u a lified
service person must connect
replace to gas supply. Follow
all local codes.

CAUTION: For propane/LP
units, never connect replace di­rectly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install
the external regulator between
the replace and propane/LP
supply.

WARNING: Fo r n a t u r al

gas, never connect heater to
private (non-utility) gas wells.
This gas is commonly known
as wellhead gas.

Installation Items Needed

Before installing replace, 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 exible 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-certied 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" of water. If you do not reduce incoming gas
pressure, replace regulator damage could occur.
Install external regulator with the vent pointing
down as shown in Figure 31. 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" inside diameter or greater to
allow proper gas volume to re­place. 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 replace (see Figure 32, page 21).

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 replaces.

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 replace 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 32. Locate
sediment trap/drip leg where it is within reach for
cleaning. Install in piping system between fuel
supply and replace. 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 replace gas controls. If
sediment trap/drip leg is not installed or is installed
wrong, replace may not run properly.

Safety Features

When away from home for an extended period
of time or as a child safety feature to prevent

accidental ignition of the replace, the receiver

ON/OFF/REMOTE switch should be in the
OFF position.

Auto Shutoff Feature

1. If the average room temperature exceeds
82 degrees Fahrenheit (28 degrees Centi­grade), the hand-held remote control will
perform a safety override and shut the

replace off. This feature is not available

in the MANU mode.

2. The receiver continuously receives signals
from the hand-held remote to control the
room temperature. If the hand-held remote
is misplaced, obstructed or for any reason
cannot transmit to the receiver, the receiver

will shut off the replace after 8 minutes.

Key Pad Lock Feature

This feature allows the user to lock/unlock the
keypad on the hand-held remote in the MANU or
AUTO mode to prevent inadvertent operation (i.e.
children operating the hand-held remote control,
etc.). The keypad is locked in either on or off. Press
the POWER and LOCK buttons together to turn
the unit on or off.

BLOWER ACCESSORY

Locate the blower controls by opening the lower

louver panel on the replace. Blower controls

are located on the right side of the switch
bracket to the left just inside the louver panel.

The BK manual blower and the BKT thermo­statically-controlled blower have an ON setting
and an OFF setting. The blower will only run
when the switch is in the ON position. In the
OFF position, the blower will not operate.

Note for BKT Only: If you are using BKT
blower with optional thermostat (wall mounted
or remote control) for the replace, your re­place and blower will not turn on and off at the

same time. The replace 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 rebox temperature decreases.

The blower helps distribute heated air from

the replace. Periodically check the louvers of
the rebox and remove any dust, dirt or other
obstructions that will hinder the ow of air.

INSPECTING BURNERS

Check pilot ame pattern and burner ame pat­terns often.

PILOT ASSEMBLY

The pilot assembly is factory preset for the proper
ame height. Alterations may have occurred dur­ing shipping and handling. Call a qualied service
person to readjust the pilot if necessary.

The height of the thermopile must be 3/8" to 1/2"
above the pilot ame as shown in Figure 54. The
thermocouple must be at a height of about 1/8"
above the pilot ame. The ame from the pilot
burner must extend beyond both the thermocouple
and thermopile.

BURNER FLAME PATTERN

Burner ames will be steady; not lifting or oating.
Flame patterns will be different from unit to unit
and will vary depending on installation type and
weather conditions.

If the vent conguration is installed incorrectly,
the ames will lift or "ghost". This can be danger­ous. Inspect the ames after installation to ensure
proper installation and performance.

Figure 56 shows a typical ame pattern.

If burner ame pattern differs from that described:

• turn replace off (see To Turn Off Gas to Ap-

pliance, page 27)

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 rst 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 24 of this manual when removing glass
door for cleaning.

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 qualied service person.

2. Remove the vent cap and shine a ashlight
into the vent. Remove any foreign material.

3. Check for evidence of excessive condensation.
Continuous condensation can cause corrosion
of caps, pipes and ttings 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
tting has been disturbed and loosened. Check
mechanical supports such as wall straps for
rigidity.

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 qualied 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 specic legal rights and you may also have other rights that vary from state to state.
