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 clearances
(see Figures 1 and 2).
2. Consider a location where the fireplace will
not be affected by drafts, air conditioning
ducts, windows or doors.
3. A location that avoids the 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).

Minimum/Maximum Chimney Height for
Residential Installation
The minimum height of the chimney, measured
from the base of the fireplace to the flue gas outlet
of the termination, is 16 feet for straight flue or a
flue with one elbow set. The maximum distance
between elbows is 6 feet. For systems with two
elbow sets, the minimum height is 22 feet. The
maximum height of any system is 50 feet. This
measurement includes the fireplace, chimney sec
-
tions and the height of the termination assembly
at the level of the flue gas outlet (see Figure 15,
page 11).
Minimum/Maximum Chimney Height for
Outdoor Installation
The minimum height of the chimney, measured
from the base of the fireplace to the flue gas outlet
of the termination, is 9.5 feet (minimum of 4 feet
of chimney pipe sections required for outdoor
installation).
FRAMING
1. Frame the opening for the fireplace using the
dimensions shown in Figures 1 and 2.
2. If the fireplace is to be installed directly on
carpeting, tile (other than ceramic) or any
combustible material other than wood floor
-
ing, the fireplace must be installed upon a
metal or wood panel extending the full width
and depth of the fireplace.
3. Set the fireplace directly in front of this open
-
ing and slide the unit back until the nailing
flanges touch the side framing.
4. Check the level of the fireplace and shim with
sheet metal if necessary.
5. Before securing fireplace to prepared framing,
the ember protector (provided) must be placed
between the hearth extension (not supplied)
and under the bottom front edge of the fire
-
place to protect against glowing embers falling
through. If the fireplace is to be installed on
a raised platform, a Z-type ember protector
(not supplied) must be fabricated to fit your
required platform height. The ember protector
should extend under the fireplace a minimum
of 1
1
/
2
". The ember protector should be made
of galvanized sheet metal (28 gauge minimum
to prevent corrosion.
6. Using screws or nails, secure the fireplace to
the framing through flanges located on the
sides of the fireplace.
