PRODUCT FEATURES
These are a few facts that can help you understand
and enjoy your direct-vent fireplace:
• The dedicated top vent for this fireplace 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 vent kits and components for your
application and follow the venting instructions
to plan your installation.
• This fireplace may be installed in any room pro
-
vided that all rules of the housing authority and
these installation instructions are followed.
• This fireplace 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 fireplace outlet when
framing.
• Each time you turn on your fireplace, you may
notice some amount of condensation on the in
-
side 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 oper
-
ating unit. It is highly efficient 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 efficient location for
your DESA/Vexar 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
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 venting to a chim
-
ney 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 material
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.
• Your fireplace 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 fireplace,
except where standoff spacers are integrally
attached. If standoff spacers are attached to your
fireplace, 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 fireplace, it
is recommended that you maintain a minimum
18" above top of louver opening.
