FIREPLACE INSTALLATION

SELECTING LOCATION

T o determine safest and most efficient location
for fireplace, 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 fireplace 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

fireplace (see Optional Outside Air Kit on
page 7).

MINIMUM CLEARANCE TO
COMBUSTIBLES

Back and sides of fireplace 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 flanges
** 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 fireplace to flue gas outlet of termina­tion, is 11.5 feet for straight flue or a flue with
one elbow set. Maximum distance between
elbows is 2 feet. For systems with two elbow
sets, minimum height is 22 feet. Maximum
height of any system is 28 feet. This measure­ment includes fireplace, chimney sections and
height of termination assembly at level of flue
gas outlet (see Figure 18, page 11).

FRAMING

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

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 this open-
ing and slide unit back until nailing flanges
touch side framing.

4. Check level of fireplace 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 fireplace
to protect against glowing embers falling
through. If fireplace is to be installed on
a raised platform, a Z-type ember protec­tor (not included) must be fabricated to
fit your required platform height. Ember
protector should extend under fireplace 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 fireplace to
framing through flanges located on sides
of fireplace.

HEARTH EXTENSION

A hearth extension projecting a minimum of
20" in front of and a minimum of 12" beyond
each side of fireplace opening is required to
protect combustible floor construction in front
of fireplace. 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 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 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 fireplace frame and hearth
extension with a noncombustible material
(see Figure 3).

WARNING: Hearth extension
is to be installed only as shown
in Figure 3.
