FIREPLACE INSTALLATION
To determine the safest and most efcient location
for the replace, 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 replace 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 replace
(see Optional Outside Air Kit on page 8).

quired air spaces with insulation
or other materials.
The minimum height of the chimney, measured
from the base of the replace to the ue gas outlet
of the termination, is 16 feet for straight ue or a
ue 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 replace, chimney sec-
tions and the height of the termination assembly
at the level of the ue gas outlet (see Figure 15,
page 11).
1. Frame the opening for the replace using the
dimensions shown in Figures 1 and 2.
2. If the replace is to be installed directly on
carpeting, tile (other than ceramic) or any
combustible material other than wood oor-
ing, the replace must be installed upon a
metal or wood panel extending the full width
and depth of the replace.
3. Set the replace directly in front of this open-
ing and slide the unit back until the nailing
anges touch the side framing.
4. Check the level of the replace and shim with
sheet metal if necessary.
5. Before securing replace to prepared framing,
the ember protector (provided) must be placed
between the hearth extension (not supplied)
and under the bottom front edge of the re-
place to protect against glowing embers falling
through. If the replace is to be installed on
a raised platform, a Z-type ember protector
(not supplied) must be fabricated to t your
required platform height. The ember protector
should extend under the replace a minimum
of 1
1
/

". The ember protector should be made
of galvanized sheet metal (28 gauge minimum
to prevent corrosion.
6. Using screws or nails, secure the replace to
the framing through anges located on the
sides of the replace.
