This replace must be installed by a qualied (cer-

ti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 combus-

tion 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.

   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.

ers and circulating air passages clean. More

frequent cleaning may be needed due to ex-

cessive lint and dust from carpeting, bedding

material, etc. Turn off the gas valve and pilot

light before cleaning replace.

6. Have venting system inspected annually by a

qualied service person. If needed, have vent-

ing system cleaned or repaired. See Cleaning

PRODUCT FEATURES

These are a few facts that can help you understand

and enjoy your direct-vent replace:

• The CD36R dedicated rear vent is best suited

for ush 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 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 unit for your application and

follow the venting instructions to plan your

installation.

• This replace 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 mil-

livolt 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 automati-

cally lights the pilot ame when the replace

is turned on.

• All models 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.

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 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 clear-

ance 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 spac-

ers can be placed directly against wall or framing

material. See framing details on page 7.

www.desatech.com

116035-01E6

• 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.

• 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 (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 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 and restops

when penetrating 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 basic types of direct-vent in-

stallation:

• Horizontal Termination

• Vertical Termination

Horizontal Termination Installation

IMPORTANT: Horizontal square terminations

require only inner portion of wall restop. Hori-

zontal installations using round termination require

exterior portion of wall restop (see Figure 20,

page 14).

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 18 through 25 on

pages 13 through 16 show different congura-

tions 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 vent-

ing 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.

 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 11). 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.

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

/4" x 10

/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

(see Figure 12).

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 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.

three nails per side (see Figure 27).

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 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

" 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 12, page 11.

Figure 27 - Installing Firestop

If area above is not a room, install restop

below framed hole.

If area above is a room or insulated area,

install restop above framed hole.

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 26, page 16). 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 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

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.
