PRE-INSTALLATION
PREPARATION
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 chimney ue serving
a separate solid-fuel burning replace or appliance.
• Due to high temperatures, do not locate this replace in high traf-
c 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.
• Your replace 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 replace,
except where standoff spacers are integrally attached. If standoff
spacers are attached to your replace, 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 replace, 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 replace against an already existing framing member.
• Do not recess termination cap into a wall or siding.
• You may paint the termination cap with 450º F (232º C) heat-
resistant paint to coordinate with the exterior nish.
• 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.
