FIREPLACE INSTALLATION

SELECTING LOCATION

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 Figures 1 and 2).

2. Consider a location where the replace
will not be affected by drafts, air condition­ing ducts, windows or doors.

3. A location that avoids the 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 6).

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 5
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 for

Residential Installation

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

Minimum/Maximum Chimney Height for

Outdoor Installation

The minimum height of the chimney, mea­sured from the base of the replace to the
ue gas outlet of the termination, is 7 1/2 feet
(minimum of 4 feet of chimney pipe sections
required for outdoor installation).

FRAMING

1. Frame opening for fireplace using the
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, 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 this open­ing and slide unit back until nailing anges
touch side framing.

4. Check the level of the replace and shim
with sheet metal if necessary.

5. Before securing fireplace to prepared
framing, the ember protector (provided)
must be placed between the 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 Z­type ember protector (not supplied) must
be fabricated to t your required platform
height. The ember protector should ex­tend under replace 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 replace to
framing through anges located on sides
of replace.

DRAIN PAN (DP36)

For outdoor installations, the replace enclo­sure must allow for adequate drainage and
fresh air ventilation. It is recommended that
a sealed, corrosion resistant catch pan with
provision for drainage be installed under the
replace within the replace enclosure (see
Accessories on page 16).

HEARTH EXTENSION

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 the 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 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 the manufacturer or supplier of
the noncombustible material. If the 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 the hearth extension from
shifting and seal gap between the 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 12" of the replace opening.
Combustible materials above 12" and pro­jecting more than 11/2" from the fireplace
must not be placed less than 15" from the
top opening of the replace (NFPA STD 211,
Sec. 7-3.3.3).

Mantels or any other combustible material
also may come up to the side edge of the
black metal face of the replace just as long
as the projection from the front face fall within
the limit shown in Figure 4.

VENTING INSTALLATION

OPTIONAL OUTSIDE AIR KIT
(MODEL AK4/AK4F)

The installation of an outside air kit should be
performed during the rough framing of the re­place due to the nature of it's location. Outside
combustion air is accessed through a vented
crawl space (AK4F) or through a sidewall (AK4).
See Figure 22 on page 13 for instruction of
operating air kit.

CAUTION: Combustion air
inlet ducts shall not terminate
in attic space.

The maximum height for the
air vent can not exceed 3 feet
below the ue gas outlet of the

termination.

CHIMNEY PIPE

The FMI PRODUCTS, LLC chimney system
consists of 12", 18", 24", 36" and 48" snap­lock, double-wall pipe segments, planned
for maximum adaptability to individual site
requirements. Actual lengths gained after t­ting overlaps must be taken into consideration
(lineal gain) and are given in the lineal gain
chart (see Figure 6). Lineal gain is the actual
measurable length of a part after two or more
parts are connected. For Canada, use chimney
parts designated "HT".
