REQUIREMENTS
Determine the safest and most efficient loca-
tion for your Vanguard 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 loca-
tions. Read all venting information in this
manual. Be aware of all restrictions and
precautions before deciding the exact loca-
tion for your fireplace.
When deciding the location of your fire-
place, follow these rules:
1. Do not connect this fireplace to a chim-
ney flue serving a separate solid-fuel
burning fireplace or appliance.
2. Due to high temperatures, do not lo-
cate this fireplace in high traffic areas
or near furniture or draperies.
3. Proper clearances must be maintained.
4. If your fireplace is to be installed di-
rectly 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.

FRAMING AND FINISHING
Figures 4 and 5 show typical framing of this
fireplace. Figure 6 on page 5 shows framing
for corner installation. All minimum clear-
ances must be met. Do not install fireplace
directly on carpeting, vinyl tile, or any com-
bustible material other than wood. The fire-
place must set on a metal or wood panel
extending the full width and depth of the
fireplace.
See Accessories on pages 34 and 35 for
mantel kits available for this fireplace. If you
are using a separate combustible mantel piece,
refer to Figure 7 on page 5 for proper instal-
lation height. You can install noncombustible
mantels at any height above the fireplace.
Note:
Noncombustible mantels may discolor!
