To determine the safest and most efcient 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).

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
/
2
". 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.
