SELECTING LOCATION

To determine safest and most efcient location
for replace, 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 replace 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

replace (see Optional Outside Air Kit on
page 7).

MINIMUM CLEARANCE TO
COMBUSTIBLES

Back and sides of replace 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 anges
** See step 2 of Framing

WARNING: Do not pack re­quired air spaces with insulation
or other materials.

Minimum/Maximum Chimney Height

Minimum height of chimney, measured from
base of replace to ue gas outlet of termina­tion, is 14.5 feet for straight ue or a ue with
one elbow set. Maximum distance between
elbows is 6 feet. For systems with two elbow
sets, minimum height is 22 feet. Maximum
height of any system is 50 feet. This measure­ment includes replace, chimney sections and
height of termination assembly at level of ue
gas outlet (see Figure 18, page 11).

FRAMING

1. Frame opening for replace using dimen­sions shown in Figures 1 and 2.

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 this open­ing and slide unit back until nailing anges
touch side framing.

4. Check level of replace 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 replace
to protect against glowing embers falling
through. If replace is to be installed on
a raised platform, a Z-type ember protec­tor (not included) must be fabricated to
t your required platform height. Ember
protector should extend under replace a
minimum of 1 1/2". Ember protector should
be made of galvanized sheet metal (28
gauge minimum) to prevent corrosion.

6. Using screws or nails, secure replace to
framing through anges located on sides
of replace.

FIREPLACE INSTALLATION

HEARTH EXTENSION

A hearth extension projecting a minimum of
20" in front of and a minimum of 12" beyond
each side of replace opening is required to
protect combustible oor construction in front
of replace. 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 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 covered, use noncombustible mate­rial such as tile, slate, brick, concrete, metal,
glass, marble, stone, etc. Provide a means
to prevent hearth extension from shifting and
seal gap between replace frame and hearth
extension with a noncombustible material
(see Figure 3).

WARNING: Hearth extension

is to be installed only as shown
in Figure 3.

MANTELS

A mantel may be installed if desired (see
Figure 4). Woodwork such as wood trims,
mantels or any other combustible material
projecting from front face must not be placed
within 12" of replace opening (and within 9"
of top louver opening). Combustible materi­als above 12" and projecting more than 1 1/2"
from replace must not be placed less than
12" from top opening of replace (NFPA STD
211, Sec. 7-3.3.3).

Mantels or any other combustible material
may come up to side edge of black metal face
of replace if projection from front face falls
within limits shown in Figure 5.

FAN/BLOWER KIT ASSEMBLY

Fan or blower kit is optional with this replace
(for circulating models only). Use of blowers
or fans other than those manufactured by
FMI PRODUCTS, LLC voids warranty. Fan
is operated by pressing rocker switch (see
Figure 6) in lower right hand corner of replace
face. Blower is operated by turning control
knob (not shown).

Fan/blower kit electrical connections are
made through electrical cover plate on side
of replace a shown in Figure 6.
