FIREPLACE INSTALLATION
FRAMING
1. Frame opening for replace using dimen-
sions shown in Figures 4 and 5.
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 open-
ing and slide unit back until nailing anges
touch side framing.
4. Check level of the replace and shim with
sheet metal if necessary.
5. Before securing fireplace to prepared
framing, ember protector (provided) 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 pro-
tector (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 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.

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 clear-
ances (see Figures 4 and 5).
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 8).
MINIMUM CLEARANCE TO

WARNING: Do not pack re-
quired air spaces with insulation
or other materials.
Minimum/Maximum Chimney Height for
Residential Installation
Minimum height of chimney, measured from
base of replace to ue gas outlet of termina-
tion, is 16 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 measure-
ment includes replace, chimney sections and
height of termination assembly at level of the
ue gas outlet (see Figure 15, page 11).
Minimum/Maximum Chimney Height for
Outdoor Installation
Minimum height of chimney, measured from
base of replace to ue gas outlet of termina-
tion, is 9.5 feet (minimum of 4 feet of chimney
pipe sections required for outdoor installation).

www.fmiproducts.com
124379-01A 7
Note: For outdoor installations, fireplace
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
replace within replace enclosure.
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 conduc-
tivity 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 manufacturer or supplier of
noncombustible material. If hearth extension
is to be covered, use noncombustible mate-
rial 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 6).
WARNING: Hearth extension
is to be installed only as shown
in Figure 6.

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. The pipe sections must
be assembled independently as the chimney is
installed. When connecting chimney directly to
the replace, the inner ue pipe section must
be installed rst with the lanced side up. The
outer pipe section can then be installed over
5 the ue pipe section with the hemmed end
up. Press down on each pipe section until the
lances securely engage the hem on the replace
starter. The wire will assure the proper spacing
between the inner and outer pipe sections.

CHIMNEY PIPE
The FMI PRODUCTS, LLC chimney system
consists of 12", 18", 24", 36" and 48" snap-
lock, double-wall pipe segments, planned
for maximum adaptability to individual site
requirements. Actual lengths gained after
tting overlaps must be taken into consider-
ation (lineal gain) and are given in the lineal
gain chart (see Figure 9). Lineal Gain is the
actual measurable length of a part after two or
more parts are connected. For Canada, use
chimney parts designated "HT".
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).
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.
WARNING: The opening in
the collar around the chimney at
the top of the replace must not
be obstructed. Never use blown
insulation to ll the chimney
enclosure.

Continue to assemble chimney sections as
outlined above, making sure that both the
inner and outer pipe sections are locked to-
gether. When installing double wall snap-lock
chimney together, it is important to assure
the joint between the chimney sections is
locked. Check by pulling chimney upward
after locking. The chimney will not come apart

Screws
if properly locked. It is not necessary to add
screws to keep the chimney together (excep-
tion, see Figure 10).
USING ELBOW OFFSETS (30E-12DM)
1. To achieve desired offset, you may install
combinations of 12", 18", 24", 36" and 48"
length of double wall pipe (see offset chart
and Figure 10).
2. Chimney weight above offset rests on
return elbow. Straps must be securely
nailed to rafters or joists (see Figure 11,
details A and B).
3. Maximum length of pipe between sup-
ports (return elbow or 12S-12DM) is 6'
of angle run. Maximum of two 6' angle
run sections per chimney system (see
Figure 12, page 10).
4. All pipe connections between the offset
and return must be secured with two
screws on the outer pipe only (see
Figure 10). Do not penetrate the inner
stainless.

FIRESTOP SPACERS (FS-10,
1100EFS-10DM FOR 36" MODELS)
Firestop spacers are required at each point
where the chimney penetrates a oor space.
Their purpose is to establish and maintain
the required clearance between the chimney
and the combustible materials. When the pipe
passes through a framed opening into a living
space above, the restop must be placed onto
the ceiling from below as shown in Figure 13.
They also provide complete separation from
one oor space to another or attic space as
required by most codes. When the double wall
pipe passes through a framed opening into an
attic space, the restop must be placed into an
attic oor as shown in Figure 14.

PENETRATING ROOF
To maintain a 1" (36" Models) or 2" (42/50"
Models) clearance to the pipe on a roof with a
pitch, a rectangular opening must be cut.
1. Determine center point through which pipe
will penetrate roof.
2. Determine center point of roof. Pitch is
distance the roof drops over a given span,
usually 12". A 6/12 pitch means that roof
drops 6" for each 12" measured horizon-
tally down from roof rafters.
3. Use roof opening chart (Figure 15, page
11) to determine correct opening length
and ashing required.
4. Remove shingles around opening mea-
sured. Cut out this section.

FLASHING INSTALLATION (V6F-10DM
OR V12F-10DM)
Determine the ashing to be used with the roof
opening chart. Slide ashing over pipe until
base is at against roof. Replace as many
shingles as needed to cover exposed area
and ashing base. Secure in position by nail-
ing through shingles (see Figure 16). DO NOT
NAIL THROUGH FLASHING CONE.
Installing Flashing on a Metal Roof
When installing the ashing on a metal roof,
it is required that putty tape be used between
the ashing and the roof. The ashing must be
secured to the roof using #8 x 3/4" screws and
then sealed with roof coating to prevent leak-
age through the screw holes. A roof coating
must also be applied around the perimeter of
the ashing to provide a proper seal.
Storm Collar Installation (SC2-1)
Place storm collar over pipe and slide down
until it is snug against the open edge of the
ashing (see Figure 17). Apply waterproof
caulk around the perimeter of the collar to
provide a proper seal.

10 FOOT RULE
All ue gas outlet chimney terminations must
extend a minimum of 3 feet in height above the
highest point where it passes through the roof
and must be at least 2 feet above the high-

distance of 10 feet (see Figure 20).
FINISHING FIREPLACE
Combustible materials, such as wallboard,
gypsum board, sheet rock, drywall, plywood,
etc. may make direct contact with sides and top
around the replace face. It is important that
combustible materials do not overlap the face
itself. Brick, glass, tile or other noncombustible
materials may overlap the front face provided
they do not obstruct essential openings like
louvered slots or any other opening. When
overlapping with a noncombustible facing
material, use only noncombustible mortar or
adhesive.

CHASE INSTALLATIONS
Instructions for chase installations are
included with the chase style termination
chosen. In a multiple chase installation, be
sure to provide adequate distance between
terminations to prevent smoke spillage from
one termination to another. We suggest that
terminations be separated at least 24", center
to center and stacked at a vertical height dif-
ference of 18" (see Figure 19).
Note: If a decorative shroud is to be installed,
contact the manufacturer for specications.

OPERATION AND MAINTENANCE GUIDELINES
GLASS DOORS
Glass doors are optional with the replace.
When replace is in operation, doors must be
fully opened or fully closed position only or a
re hazard may be created (see Figure 30,
page 17).
A replace equipped with glass doors operates
much differently than a replace with an open
front. A replace with glass doors has a limited
amount of air for combustion.

holes at front of rebox and secure with
screws removed in step 5.
7. Place ash box in place. Replace center
ash refractory. DOOR ADJUSTMENT
Remove doors and slightly loosen lower pivot
clips and upper spring clips. Replace doors
and fully close them. Use 1/8" shims (any
material) to level doors. Once proper setting
is achieved, carefully open doors enough so
that you can access spring clips with a Phillips
screwdriver. Tighten screws. See Figure 29.

Excessive heat within the replace can result if
too large a re is built or if combustion air gate
is not completely open. The following tips should
be followed to assure that both the replace
and glass door retain their beauty and function
properly. Both the ue damper and glass doors
must be fully opened before starting re. This will
provide sufcient combustion air and maintain
safe temperatures in rebox.

HANDLE OPERATION
The damper handle, which opens and closes
the damper blade, is located in the upper front
face of the replace. Pushing the handle for-
ward and up through the keyway slot will free
damper blade to automatically open. Pushing
the handle forward and down will lock damper
blade closed (see Figure 31).
IMPORTANT: The glass must be allowed to
warm slowly and evenly. The tempered glass will
withstand a gradual temperature rise to 550° F,
which is more than a normal re will generate.
Such materials as pitch/wax laden logs, very dry
mill end lumber and large amounts of paper or
cardboard boxes can create an excessively hot
re and should not be burned in this replace.
Always keep the re well back from the doors
and never allow ames to contact the glass.
WARNING: Fireplaces
equipped with glass doors
should be operated only with
doors fully opened or doors fully
closed. Doors, if left partly open,
may draw gas and ame out of
the replace opening creating
risks of both re and smoke.
Cleaning Glass
Clean glass with any commercial glass cleaner
or soap and water. Do not use any abrasive
material to clean glass. Do not clean glass with
any cool water if glass is still hot from the re
and smoke.
