FRAMING
1. Frame opening for fireplace using dimen-
sions shown in Figures 4 and 5.
2. If fireplace is to be installed directly on
carpeting, tile (other than ceramic) or any
combustible material other than wood
flooring, fireplace must be installed upon
a metal or wood panel extending full width
and depth of fireplace.
3. Set fireplace directly in front of this open-
ing and slide unit back until nailing flanges
touch side framing.
4. Check level of the fireplace and shim with
sheet metal if necessary.
5. Before securing fireplace to prepared
framing, ember protector (provided) must
be placed between hearth extension (not
supplied) and under bottom front edge of
fireplace to protect against glowing embers
falling through. If fireplace is to be installed
on a raised platform, a Z-type ember pro-
tector (not supplied) must be fabricated to
fit your required platform height. Ember
protector should extend under fireplace a
minimum of 1
1 /
2
". Ember protector should
be made of galvanized sheet metal (28
gauge minimum to prevent corrosion.
6. Using screws or nails, secure fireplace to
framing through flanges located on sides
of fireplace.

SELECTING LOCATION
To determine the safest and most efficient
location for the fireplace, you must take into
consideration the following guidelines:
1. The location must allow for proper clear-
ances (see Figures 4 and 5).
2. Consider a location where fireplace will
not be affected by drafts, air conditioning
ducts, windows or doors.
3. A location that avoids cutting of joists or
roof rafters will make installation easier.
4. An outside air kit is available with this
fireplace (see Optional Outside Air Kit on
page 8).
