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 1 and 2, page 4).
2. Consider a location where the heat output
will not be affected by drafts, air condition-
ing 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 included with this re-
place (see Outside Air Kit on page 6).

1. Frame opening for replace using dimen-
sions shown in Figures 1 and 2.
2. The replace may not be installed on
carpeting, tile (other than ceramic) or any
combustible material other than wood
ooring, replace must be installed on a
metal or wood panel extending full width
and depth of replace. (It is acceptable to
cover two outside ends or columns of top
louver panel leaving four center columns
open).
3. Set replace directly in front of this open-
ing 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 replace to prepared fram-
ing, metal 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". The ember protector
should be made of metal material.
6. Using screws or nails, secure replace to
framing through anges located on sides
of replace (see Figure 4).
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 oor construction in
front of the replace. Use an equal material
which meets the following specications: a
layer of noncombustible, inorganic material
having a thermal conductivity of k = .84 BTU
IN/FT2 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 ex-
tension 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 5).

OUTSIDE AIR KIT
Installation of an outside air kit should be
completed during the rough framing of
replace due to nature of its location. The
supplied ex duct measures approximately
10" compressed and up to approximately 36"
extended. Outside combustion air is accessed
through mobile home oor using air kit model
AK6E, included with the replace, or a side
wall using optional air kit model AK6-WE (see
Accessories on page 18).
Installer may choose either left or right side
mounting to allow for proper wall/rafter
clearances.
For AK6-WE Only: Construct a 4.5" x 4.5"
framing or opening on exterior wall (see
Figure 6, page 6).
For AK6E Only: The outside air vent is in-
stalled through a ventilated crawl space (see
Figure 7, page 7).

1. Locate and remove air inlet cover plate on
replace‘s outer surround. Save screws.
2. Cut out any visible insulation that may
obstruct airow.
3. Extend ex duct to attach air inlet tube.
4. Insert inner tab of inlet tube into mating
slot next to opening.
5. Place outer tab of inlet tube over mating
hole next to opening and secure with
screws removed from cover plate in
step 1.
6. Install outside air vent termination in a
location that will not be obstructed by
bushes, snow, etc. Locate vent near the
replace to make ex duct installation
easier.
CHIMNEY PIPE
The chimney system approved for this
replace 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 8). Lineal Gain is the
actual measurable length of a part after two
or more parts are connected.

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. The wire spacer will
assure proper spacing between inner and outer
pipe sections.

Continue to assemble chimney sections as
outlined above, making sure that both inner
and outer pipe sections are locked together.
When installing double wall snap-lock chimney
together, it is important to assure that the 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 14, page 11).

(FST-A)
Adjustable Firestop Thimble Assembly (FST-A)
is used to provide necessary air space and
clearance between chimney pipe and insula-
tion in attic space of a manufactured home.
To install thimble assembly, determine dis-
tance between ceiling joist and roof framing.
Attach adjustable thimble to restop spacer
so that assembly will cover distance. Adjust-
able thimble should be even with or above
rooine. Sheet metal screws or staples may
be used to attach thimble to restop spacer.
An opening large enough to allow insertion
of restop thimble assembly will be required
in ceiling. Attach restop/thimble assembly to
ceiling/ceiling joist using screws or staples as
shown in Figure 9. A minimum of 8 screws or
staples should be used.
Firestop thimble assembly should also be
used where there is a cathedral ceiling, in-
sulation barrier and roof, all in one assembly
in a manufactured home (see Figure 9). The
FST-A thimble can be used in any one of
three common ceiling pitches; at, 1.5"/12'
and 2.5"/12'.
An opening big enough to allow insertion of
restop thimble assembly will be required.
This opening depends on the pitch of your
ceiling. If your ceiling is a at or 1.5"/12'
pitch, you must use adapter plate provided to
seal unwanted openings. For 2.5"/12" pitch,
discard adaptor.

If adapter is needed, secure it onto restop
using holes provided (see Figure 10). The
row of holes on sides of thimble is provided
to allow for pitch variances. Position restop
(top and bottom side) and thimble to desired
angle and secure with screws provided.
Insert thimble and firestop into prepared
opening and secure to ceiling by nailing
through firestop flanges. Thimble should
be even with or above roofline. Thimble
extensions are available (as an option) when
required. See Accessories on page 18.
Note: If there is a second story in the home,
restop spacer 3600FS-8DM will be required.
See Firestop Spacers, page 11.
PENETRATING ROOF
To maintain a 1" clearance to pipe on a roof
with a pitch, a rectangular opening must be
cut.
1. Determine center point through which pipe
will penetrate the roof.
2. Determine center point of the roof. Pitch
is the distance the roof drops over a given
span, usually 12". A 6/12 pitch means that
the roof drops 6" for each 12" measured
horizontally down from roof rafters.
3. Use roof opening chart (Figure 11) to
determine correct opening length and
ashing required.
4. Remove shingles around opening mea-
sured. Cut out this section.
5. Add next sections of pipe until end pen-
etrates roof line. Check to see that proper
clearances are maintained. Extend chim-
ney by adding sections of double wall
pipe until pipe is minimum of 30" above
highest point of roof cutout. Termination
and chimney must extend a minimum of
36" above highest point where it passes
through roof.

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

Installing Flashing on a Metal Roof
When installing ashing on a metal roof, it
is required that putty tape be used between
ashing and roof. Flashing must be secured
to roof using #8 x 3/4" screws and then sealed
with roof coating to prevent leakage through
screw holes. A roof coating must also be
applied around the perimeter of ashing to
provide a proper seal.

Gas line hook up should be done by your
supplier or a qualied service person.
Note: Before you proceed, make sure your
gas supply is turned off.
A gas line may be installed for the purpose
of installing a vented or vent free appliance
available through your local distributor. Use
only a 1/2" black iron pipe and appropriate
ttings. When installing a gas line, a shutoff
valve designed for installation outside appli-
ance is recommended.
1. Remove knockout indentation on refrac-
tory or rebrick wall located above the re-
fractory hearth oor. Knockout indentation
must be rmly tapped with any solid object
such as a 1/2" dowel until it is released.
Remove fragmented portions of refractory

2. Remove gas line cover plate located on
either side of replace and pull out insu-
lation from gas line conduit sleeve. Save
insulation for reuse. Replace screws.

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 lou-
vered slots or any other opening. When overlap-
ping with a noncombustible facing material, use
only noncombustible mortar or adhesive.

A mantel may be installed if desired (see
Figure 24). Woodwork such as wood trims,
mantels or any other combustible material
projecting from the front face must not be
placed within 9" of the replace opening. Com-
bustible materials above 9" and projecting
more than 1-1/2" from the replace must not
be placed less than 12" from the top opening
of the replace (NFPA 211, Section - Clear-
ance from Combustible Material).

Glass doors are standard with fireplace.
When replace is in operation, doors must
be FULLY OPENED or FULLY CLOSED
position only or a re hazard may be created
(see Figure 25).
A replace equipped 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. Excessive heat
within 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 replace and glass door
retain their beauty and function properly.
Both ue damper and glass doors must be
fully opened before starting the re. This will
provide sufcient combustion air and maintain
safe temperatures in rebox.
IMPORTANT: Glass must be allowed to
warm slowly and evenly. Tempered glass will
withstand a gradual temperature rise to 550°
Fahrenheit, 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 pa-
per or cardboard boxes can create an exces-
sively hot re and should not be burned in this
replace. Always keep re back from doors
and never allow ames to contact glass.

near bottom corner of front face opening
and swing door to vertical position making
sure top pins slide into door track. Door is
installed when top door pin snaps into spring
clip (see Figure 26).

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 27.

Clean the 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 re and smoke.
DAMPER OPERATION
The damper handle, which opens and closes
damper blade, is located inside rebox at cen-
ter towards back wall. Pushing handle back
in keyway slot will free damper blade to au-
tomatically open. To close, reach in and push
handle back into keyhole slot then pull down
and forward to lock it in place (see Figure 28).
Damper is not designed to be airtight. A small
gap around damper blade is normal.
