FIREPLACE INSTALLATION
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 CLEARANCE TO COMBUSTIBLES
Back and sides of fireplace 3/4" minimum*
Floor** 0" minimum
Perpendicular wall to opening 12" minimum
Top spacers 0" minimum
Mantel clearances see Mantels, page 6
Chimney outer pipe surface 1" minimum
* Not required at nailing flanges
** See step 2 of Framing
WARNING: DO NOT PACK REQUIRED AIR SPACES
WITH INSULATION OR OTHER MATERIALS.
Minimum/Maximum Chimney Height
The minimum height of the chimney, measured from the base of
the fireplace to the flue gas outlet of the termination, is 14.5 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 18, 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 8 feet (minimum
of 4 feet of chimney pipe sections required for outdoor installation).

FRAMING
1. Frame opening for fireplace using dimensions shown in Figures
1 and 2.
Note:
When the fireplace is framed, the header has to be turned
on the vertical edge to maintain proper clearance.
2. If fireplace is to be installed directly on carpeting, tile 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 opening 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 protector (not included) must be fabri-
cated to fit your required platform height. Ember protector should
extend under fireplace a minimum of 1
1
/

". 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.
