SELECTING LOCATION
To determine safest and most efficient location
for fireplace, you must take into consideration
the following guidelines:
1. Location must allow for proper clearances
(see Figures 1 and 2).
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 7).

Minimum/Maximum Chimney Height
Minimum height of chimney, measured from
base of fireplace to flue gas outlet of termina-
tion, is 11.5 feet for straight flue or a flue with
one elbow set. Maximum distance between
elbows is 2 feet. For systems with two elbow
sets, minimum height is 22 feet. Maximum
height of any system is 50 feet. This measure-
ment includes fireplace, chimney sections and
height of termination assembly at level of flue
gas outlet (see Figure 18, page 11).
FRAMING
1. Frame opening for fireplace using dimen-
sions shown in Figures 1 and 2.
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 fireplace and shim with
sheet metal if necessary.
5. Before securing fireplace to prepared
framing, ember protector must be placed
between hearth extension (not included)
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 protec-
tor (not included) 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.
