These are a few facts that can help you under-
stand 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 nec-
essary 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 se-
lect the appropriate unit for your application
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.

PRE-INSTALLATION PREPARATION

LOCATION AND SpACE
REqUIREMENTS
Determine the safest and most efficient loca-
tion for your DESA Heating, LLC direct-vent
fireplace. 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 com-
mon 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 venting to a
chimney flue serving a separate solid-fuel
burning fireplace or appliance.
• Due to high temperatures, do not locate this
fireplace in high traffic 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 ma-
terial other than wood, it must be installed
on a metal or wood panel extending the full
width and depth of the fireplace. See Figure
3, page 6.

• 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 circulat-
ing 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 independently heating
the indoor air.
• Your fireplace 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 fireplace, except where standoff spac-
ers are integrally attached. If standoff spac-
ers are attached to your fireplace, these
spacers can be placed directly against wall
or framing material. See framing details on
page 7.
• If you plan on installing a television or
entertainment center recessed above
your fireplace, it is recommended that you
maintain a minimum 18" above top of louver
opening.
