SELECTING LOCATION

FIREPLACE INSTALLATION

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 Figure 1 and Figure 2, page 4).

2. Consider a location where the heat output
will not be affected by drafts, air condition-

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 Outside Air Kit on page 5).

WARNING: Do not install this

appliance in a bedroom.

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 15 feet for straight ue and 16 feet for
a ue with one elbow set. Maximum distance
between elbows is 2 feet. For systems with
2 elbow sets, minimum height is 25 feet.
Maximum height of any system is 40 feet. This
measurement includes replace, chimney
sections and height of termination assembly
at level of ue gas outlet (see Figure 15,
page 10).

FRAMING

1. Frame opening for replace using dimen­sions shown in Figure 1.

2. If replace is to be installed directly on
carpeting, tile (other than ceramic) or any
combustible material other than wood
ooring, the replace must be installed
upon a metal or wood panel extending
the 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 level of replace and shim with
sheet metal if necessary.

5. Before securing fireplace to prepared
framing, provided ember protector must
be placed between hearth extension (not
supplied) 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 supplied) 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 sheet metal (28 gauge mini­mum to prevent corrosion.

6. Using screws or nails, secure replace to
framing through anges located on sides
of replace (see Figure 2).

HEARTH EXTENSION

A hearth extension projecting a minimum of
16" in front of and a minimum of 8" beyond
each side of replace opening is required
to protect combustible oor construction in
front of replace. Use Style Crest, Inc. hearth
extension (see Accessories, page 14) HE-36
or an equal 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 the manufacturer or supplier of
the 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).

MANTELS

A mantel may be installed if desired (see
Figure 4). Woodwork such as wood trims,
mantels or any other combustible material
projecting from the front face must not be
placed within 9" of replace opening. Combus­tible materials above 9" 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
also may come up to side edge of black metal
face of replace only if projection from front
face falls within limits shown in Figure 5.
