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
serviced 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.

Location and Space Requirements
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 applica tion 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.
• 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 independantly
heating the indoor air.
• Your fireplace is designed to be used in zero clearance installa tions. Wall or framing material can be placed directly against
any exterior surface on the back, sides, or top of your fireplace,
except where stand-off spacers are integrally attached. If stand-
.
off 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 re cessed above your fireplace, it is recommended that you main tain a minimum 18” above the top of louver opening.
• When locating termination cap, it is important to observe the
minimum clearances shown in Figure 10, page 7.
• If recessed into a wall, you can avoid extra framing b position ing 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 450°F (232°C) 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 terminal area after snow
falls to prevent accidental blockage of venting system. When
using snow blowers, do not direct snow towards vent termina tion 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. Coose 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 to a chimney flue servicing
a separate solid-fuel burning fireplace or appliance.
• Do to high temperatures, do not locate this fireplace in high traf-
fic 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 exttending the full width and
depth of the fireplace. See Figure 3.

INSTRUCTIONS
NOTICE:
fore 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 servicing a
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 terminatates horizontally on an outside wall
you may install a standoff if the termination cap is to be in stalled directly on combustible finish such as vinyl, wood,
stucco, etc.
• Never run the vent downward as this may cause excessive tem peratures which could cause a fire.
• Vent pipe air space clearances to combustibles are 1” on all sides
except on the horizontal sections, which require 2” clearance
from the top of the pipe. Where the termination cap penetrates a
combustible wall, the use of a 2 piece wall firestop is required to
support the termination cap and maintain proper clearances.
• 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 vertical
firestops when penetrating ceilings, floor joists or attic spaces.
• Install hoorizontal venting with a 1/4” rise for every 12” of run

IMPORTANT:
portion of wall firestop. Horizontal installation using round termination require exterior portion of wall firestop (see Figure 18, page 11).
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 19 through 25 on pages11 through 13 show
different configurations for venting with horizontal termina tion 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).
feet. Use wall strap for this purpose.
3. Any straight pipe section, a 45°, or a 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:
elbows 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,
pipe sections may be pre-assembled and installed 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 ¾” x10 ¾” 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 of concrete , a 8 ½” hole with zero clearance is
acceptable (see Figure 12).

Noncombustible Exterior Wall: Position the horizontal vent
cap in the center of the 8 ½” round hole and attach to the exte rior wall with four wood screws provided. Before attaching
the vent cap to exterior wall, run a bead of non-hardening mastic
(pliable sealant) around the outside edges to make a seal be tween it and the outside wall.
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 stand off. Apply non-hardening mastic around outside edge of stand off. Position the standoff/cap assembly in the center of the
10 ¾ 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

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 1 ¼”.
9. Combustible Exterior Wall Only: Slide wall firestop against
interior wall surface and attach with screws provided (see Figure
16). See Figure 17 for horizontal termination details.
10. Place fireplace into position and shim with noncombustible ma terial, if needed. Nail or screw flanges to framing to secure

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.
lation instructions for required clearances (air space) to com bustibles when passing through ceilings, walls roofs, enclo sures, attic rafters, etc. Do not pack air spaces with insulation.
Also note maximum horizontal offset limitations.
2. Set 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.
NOTE:
Pay special attention to these instal-
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 Fig-
ure 11, 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 ¾” x 10 ¾” hole must be measured on the horizontal;
actual length may be larger dependiong 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 9.
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). Whenever possible, use 45º elbows
instead of 90º elbows. The 45º 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 fram ing with roofing nails. Be sure roofing material overlaps the
top edge of the flashing as shown in Figure 26. There must be
a 1” clearnace from the vent pipe to combustible materials
6. Continue to add pipe section until the height of the vent cap
meets the minimum building code requirements described in
Figure 10 on page 7.
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 kast 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.
Note:
You must increase vent height for
Figure 26 - Offset with Wall Strap and 45° Elbows
Flat Ceiling Installation
1. Cut a 10 ¾” square hole in the ceiling using the locating hole as
a center point. The opening should be framed to 10 ¾” x 10 ¾”
(273 mm x 273 mm) inside dimensions, as shown in Figure 12
on page 9 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 insula tion 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).
