SAFETY INFORMATION
-
This replace must be installed by a qualied (cer-
tied 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
inuence 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 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 sufcient 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.

installation
• Your direct-vent gas replace system (replace
and venting) is a balanced and sealed gas oper-
ating unit. It is highly efcient because it uses
outside air for combustion while independently
heating the indoor air.
PRE-INSTALLATION
PREPARATION
REqUIREMENTS
Determine the safest and most efcient 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 trafc 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.
