Determine the safest and most efcient loca-
tion for your DESA Heating, LLC 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 com-
mon 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
chimney 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.

These are a few facts that can help you under-
stand and enjoy your direct-vent replace:
• 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 (hori-
zontal). The vent pipe installation is very
important to allow for proper operation.
You must follow the venting instructions
very carefully for either vertical or horizontal
applications.
• This replace may be installed in any room
of your house provided all local codes and
these installation instructions are followed.
• This replace requires a wall switch, hand-
held remote or wall thermostat (millivolt) for
operation (see Accessories, page 42).
• This replace does not require electricity
to operate.
• Only the blower requires electricity if in-
stalled and if you plan to install the blower at
a later date, do not forget to wire the outlet at
the bottom of the replace when framing.
• A piezo ignitor and ceramic electrode cre-
ate 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 replace, you
may notice some amount of condensation
on the inside of the replace glass. This
is normal and will disappear after 10-20
minutes of operation.
• Your direct-vent gas fireplace system
(replace and venting) is a balanced and
sealed gas operating unit. It requires ap-
proximately 10-20 minutes of operating
time before the ame pattern stabilizes.
• Fireplaces with the sufx of -HA have been
designed to operate at altitudes of 4000
feet and above.
