2. If replace is to be installed directly on
carpeting, tile (other than ceramic) or any
combustible material other than wood
ooring, replace must be installed upon
a metal or wood panel extending full width
and depth of replace.
3. Set replace directly in front of opening
and slide unit back until nailing anges
touch side framing.
4. Check the level of replace 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
replace to protect against glowing embers
falling through (see Figure 7). If 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 (see Figure 6). The ember protector
should extend under 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 replace to
the framing through anges located on
sides of the replace (see Figure 8).

A hearth extension projecting a minimum of
16" in front of and a minimum of 8" beyond
each side of the replace opening is required
to protect combustible floor construction
in front of replace (see Figure 9, page 6).
Fabricate a hearth extension using a material
which meets the following specications: 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 ber, 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)
