This replace must be installed by the O.E.M.
builder or by a qualied (certied 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, con-
nected and sealed, carbon monoxide leakage
(spillage) can occur.
   Early signs of
carbon monoxide poisoning resemble the u, with
headaches, dizziness or nausea. If you have these
signs, the replace may not be working properly.
Get fresh air at once! Have replace 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
inuence of alcohol and those at high altitudes.
    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 replace.

PRODUCT FEATURES
These are a few facts that can help you understand
and enjoy your direct-vent replace:
The dedicated top vent for this replace is suited
for any application where height is necessary
to terminate the venting system either through
the roof (vertical) or to gain sufcient 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 vent kits and components for your
application and follow the venting instructions
to plan your installation.
This replace may be installed in any room pro-
vided that all rules of the housing authority and
these installation instructions are followed.
This replace is 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.
This model can accept an optional circulating
air blower when 120 VAC connection is sup-
plied. If you plan to install an optional blower,
do not forget to wire the replace outlet when
framing.
Each time you turn on your replace, you may
notice some amount of condensation on the in-
side 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 oper-
ating unit. It is highly efcient 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 efcient location for
your DESA/Vexar 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 chim-
ney 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, page 6.
Your replace is designed to be used in zero
clearance installations. Wall or framing material
can be placed directly against any exterior sur-
face 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 enter-
tainment center recessed above your replace, it
is recommended that you maintain a minimum
18" above top of louver opening.
www.desatech.com
118531-01A6
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 replace 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 nish.
There must not be any obstruction such as
bushes, garden sheds, fences, decks or util-
ity 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.

-

These models are tested and approved for use
with DESA/Vexar (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.
This model is approved to be vented either
horizontally through an outside wall or vertically
through a roof or chase enclosure using the fol-
lowing:
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.
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, ceilings or
attic spaces.
Install horizontal venting with a 1/4" rise for
every 12" of run toward the termination.

INSTALLATION PLANNING
There are two starter vent kits available for
either a horizontal or a vertical installation:
CHVK-58 Corner Horizontal Vent Kit - Intend-
ed for corner or ush installations with less than
24" of horizontal distance to the termination.
CVVK-58 - Ceiling Vertical Vent Kit - Intended
for a straight vertical installation through a ceil-
ing with less than 9' to a roof termination.
Horizontal Termination Installation
IMPORTANT: Horizontal square terminations
require only inner portion of wall restop.
1. Set the replace in its desired location and deter-
mine 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 13 and 14 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 thereplace.
2. Direct vent pipe sections and components are
designed with special twist-lock connections.
 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 sec-
tions together and twist one section clockwise
approximately one-quarter turn until the sections
are fully locked (see Figure 10). Note: Horizon-
tal 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 rst connecting the venting
system to the replace. Elbows are designed
to twist-lock into any of four 90° positions to
direct the venting system to the desired loca-
tion. 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 subassem-
blies for convenience.

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 cut-
ting 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 posi-
tion 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.

dimensions, as shown in Figure 11 on page
11 using framing lumber the same size as the
ceiling joists. If the area above the ceiling is
an insulated ceiling, you must use the restop
thimble and special restop included with the
kit to prevent insulation from contacting the
vent pipe (see Thimble Installation, page 16).
Otherwise, 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 10, page 11).
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

" 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 11, page 11.
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 Fig-
ure 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 roof-
ing nails. Be sure roong material overlaps the
top edge of the ashing 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 9 on page 9.
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. Increas-
ing 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 construc-
tion material. Make sure and meet the minimum
allowable clearances to combustibles. Do not ll
any of the required air spaces with insulation.

1. Plumb and locate knockout area for vent pipe.
2. Cut and frame ceiling joist to dimensions
shown in Figure 11, page 11.
3. Determine where restop plate should be at-
tached to thimble by test-tting thimble into
framing. Thimble should be at or above the
height of the insulation.
4. Attach thimble into restop plate using 4 hex
screws provided (see Figure 21).

sence of local code, with the
current National Electric Code,
ANSI/NFPA 70, or the Canadian
Electric Code, CSA C22.1
A prewired junction box receptacle with strain
relief is provided on the right side of the cabinet
for hard wiring the unit to a 15 Amp, 120VAC,
60Hz grounded branch circuit. If the installation
demands that the electrical supply be connected
from the left side, the entire receptacle box can
be relocated to the left side by following these
instructions:
Note: If you do not need to relocate the junction
box, to connect the electric supply follow steps 8
through 11 only:
1. Remove 2 screws and outer cover with strain
relief bushing on right side of cabinet (see
Figure 26).
2. Remove inner retaining screw on junction box
mounting tab.
3. Slide junction box up until screw mounting
tab is lined up to notch in outer cabinet.

4. Swing the junction box out and slip retaining
ange out through the slot in outer cabinet.
5. Remove two screws and outer cover on the
left side of the outer cabinet.
6. Reinsert junction box retaining ange through
slot now on the left side and swing screw
mounting tab back through notch as before.
7. Slide the junction box down till mounting tab
holes line up and replace the inner retaining
screw.
8. With junction box cover removed, pull the end
of 3-wire Romex supply line through universal
strain relief bushing on cover (see Figure 26,
page 18).
9. Strip back the outer Romex to about 4" and
connect black, white and green wires accord-
ingly using 3 wire nut connectors.
10. Tuck tailing wires into junction box and
replace junction box cover using 2 remaining
screws.
11. Tighten down strain adjustment on universal
bushing until Romex sheathing is secured.
The electrical connection is now complete.

1. Attach power cord to blower motor by rmly
pushing the two female terminals at the end of
power cord onto the two spade terminals on
blower motor (see Figure 27).
2. Attach green ground wire from power cord
to blower housing using screw provided (see
Figure 27). Tighten screws securely.
3. Place blower against lower rear wall of the
rebox outer wrapper with exhaust port di-
rected upward. The blower will t inside the
back opening and be held in position against
the back wall by magnets (see Figure 27).
4.
Be certain that all wire terminals are securely at-
tached to terminals on blower motor and that the
screw retaining the green ground wire is tight.
5. Mount speed control box by placing plastic
control shaft through opening in switch
bracket (see Figure 28).

standing unit with an accessory mantel,
determine whether the power cord will exit
the left side or the right side of the rebox.
Route power cord through exit hole and
plug the power cord into a wall receptacle
near the rebox.
b. If your rebox installation is recessed
and/or prewired, plug the power cord into
the duplex outlet provided. Refer to your
rebox owner’s manual for instructions
on wiring the duplex outlet.
CAUTION: Never touch the

Note: When installing the BKT thermostati-
cally-controlled blower, you must rst 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 as-
sembly. Insert the phillips screw into all three
pieces and tighten securely (see Figure 30).
2. Connect wire harness and power cord ter-
minals. Connect the blue jumper wire to the
blower motor terminal and the right side ter-
minal 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.
