2. If fireplace is to be installed directly on
carpeting, tile (other than ceramic) 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 opening
and slide unit back until nailing flanges
touch side framing.
4. Check the level of fireplace and shim with
sheet metal if necessary.
5. Before securing fireplace to prepared
framing, ember protector (provided) must
be placed between hearth extension (not
supplied) and under bottom front edge of
fireplace to protect against glowing embers
falling through (see Figure 7). If 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 (see Figure 6). The ember protector
should extend under 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 fireplace to
the framing through flanges located on
sides of the fireplace (see Figure 8).

HEARTH ExTENSION
A hearth extension projecting a minimum of
16" in front of and a minimum of 8" beyond
each side of the fireplace opening is required
to protect combustible floor construction
in front of fireplace (see Figure 9, page 6).
Fabricate a hearth extension using a material
which meets the following specifications: a
layer of noncombustible, inorganic material
having a thermal conductivity of K=0.84 BTU
IN/FT, HR. F (or less) at 1" thick. For example,
if the material selected has a K factor of 0.25,
such as glass fiber, the following formula
would apply:
0.25 x 1.0" = 0.30" thickness required
0.84
Thermal conductivity "K" of materials can be
obtained from manufacturer or supplier of
noncombustible material.
If hearth extension is to be raised, a “Z” type
ember protector must be used (see Figure 6
and Figure 10, page 6)
