PRODUCT FEATURES
These are a few facts that can help you understand and enjoy your
direct-vent fireplace:
• The venting system may be routed to the outside of your home
in several ways. It may vent through the roof (vertical) or it may
vent to an outside/exterior wall (horizontal). The vent pipe instal-
lation is very important to allow for proper operation. You must
follow the venting instructions very carefully for either vertical
or horizontal applications.
• This fireplace may be installed in any room of your house provided
all local codes and these installation instructions are followed.
• This fireplace requires a wall switch, hand-held remote or wall
thermostat (millivolt) for operation (see Accessories, page 36).
• This fireplace does not require electricity to operate.
• Only the blower requires electricity if installed and if you plan to
install the blower at a later date, do not forget to wire the outlet
at the bottom of the fireplace when framing.
• A piezo ignitor and ceramic electrode create spark to ignite the
pilot light. It does not require any matches, batteries or any other
sources of ignition to light the pilot.
• 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 requires approximately 10-
20 minutes of operating time before the flame pattern stabilizes.
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. 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 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 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.
• Your fireplace is designed to be used in zero clearance instal-
lations. Wall or framing material can be placed directly against
any exterior surface 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 5.
• If you plan on installing a television or entertainment center re
-
cessed above your fireplace, 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 6.
• If recessing into a wall, you can avoid extra framing by 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 450ºF (232ºC) 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 termination area after
snow falls to prevent accidental blockage of venting system.
When using snow blowers, do not direct snow towards vent
termination area.
