SELECTING FIREPLACE 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 1 and 2).
2. Consider a location where the fireplace
will not be affected by drafts, air condition-
ing 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 5).

Minimum/Maximum Chimney Height
The minimum height of the chimney, mea-
sured 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 sections and the height
of the termination assembly at the level of the
flue gas outlet (see Figure 15, page 9).
FRAMING
1. Frame the opening for the fireplace using
the dimensions shown in Figures 1 and 2.

3. Set the fireplace directly in front of this
opening 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 fram-
ing, the ember protector (provided) must be
placed between the hearth extension (not
supplied) and under the bottom front edge
of the fireplace 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 galva-
nized 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.
