SELECTING FIREPLACE 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 5).

MINIMUM CLEARANCE TO
COMBUSTIBLES

Back and sides of replace 1 1/2" min.*
Front of replace 48" min.
Floor** 0" min.
Perpendicular wall to opening 18" min.
Top spacers 0" min.
Mantel clearance see Mantels,

page 5
Chimney outer pipe surface 2" min.

* 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

The minimum height of the chimney, mea­sured from the base of the replace to the
ue gas outlet of the termination, is 16 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 15, page 9).

FRAMING

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

2. If the replace is to be installed directly
on carpeting, tile (other than ceramic) or
any combustible material including wood
ooring, the replace must be installed

on a hearth spacer designed for use with
this replace (see Replacement and Ac-
cessory Parts, page 18).

3. Set the replace directly in front of this
opening and slide the unit back until the
nailing anges touch the side framing.

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

5. Before securing replace to prepared fram­ing, the ember protector (provided) must be
placed between the hearth extension (not
supplied) and under the bottom front edge
of the replace to protect against glowing
embers falling through. If the 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 the 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 the replace
to the framing through anges located on
the sides of the replace.

HEARTH EXTENSION

A hearth extension projecting a minimum of
20" in front of and a minimum of 12" 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).

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 the front face must not be
placed within 12" of the replace opening.
Combustible materials above 12" and pro­jecting more than 1 1/2" from the replace
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.

OPTIONAL OUTSIDE AIR KIT

(MODEL AK4/AK4F)

Installation of an outside air kit should be per­formed during rough framing of replace due
to nature of it's location. Outside combustion
air is accessed through a vented crawl space
(AK4F) or through a sidewall (AK4). This re­place is equipped with a barometric damper
which allow outside air to ow into replace
automatically when needed.

CHIMNEY PIPE

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 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".

WARNING: The opening in the
collar around the chimney at the

top of the replace must not be

obstructed. Never use blown insula-

tion to ll the chimney enclosure.

ASSEMBLY AND INSTALLATION OF
DOUBLE WALL CHIMNEY SYSTEM

Each double wall chimney section consists of
a galvanized outer pipe, a stainless steel in­ner ue pipe and a wire spacer. Pipe sections
must be assembled independently as chimney
is installed. When connecting chimney directly
to replace, inner ue pipe section must be
installed rst with lanced side up. Outer pipe
section can then be installed over ue pipe
section with hemmed end up. Press down
on each pipe section until lances securely
engage hem on replace starter. Wire will
assure proper spacing between inner and
outer pipe sections.

Continue to assemble chimney sections as
outlined above, making sure both inner and
outer pipe sections are locked together. When
installing double wall snap-lock chimney to­gether, it is important to assure joint between
chimney sections is locked. Check by pulling
chimney upward after locking. Chimney will
not come apart if properly locked. It is not
necessary to add screws to keep chimney
together (exception, see Figure 9, page 8).
