INSTALLATION
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 clear-
ances (see Figures 1 and 2).
2. Consider a location where the replace
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 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.

The minimum height of the chimney, mea-
sured 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

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 fram-
ing, 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 Z-
type 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 galva-
nized 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.

122272-01C 5
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 noncom-
bustible, 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 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 the hearth extension from
shifting and seal gap between the replace
frame and hearth extension with a noncom-
bustible 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 pro-
jecting 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.

Installation of an outside air kit should be per-
formed 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 re-
place is equipped with a barometric damper
which allow outside air to ow into replace
automatically when needed.

ASSEMBLY AND INSTALLATION OF
DOUBLE WALL CHIMNEY SYSTEM
Each double wall chimney section consists of
a galvanized outer pipe, a stainless steel in-
ner 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 to-
gether, 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).

CHIMNEY PIPE
DESA Heating, 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 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".

where chimney penetrates a floor space.
Their purpose is to establish and maintain
required clearance between chimney and
combustible materials. When pipe passes
through a framed opening into a living space
above, restop must be placed onto ceiling
from below as shown in Figure 10.
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 11.

PENETRATING ROOF
To maintain a 2" clearance to pipe on 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
the distance the roof drops over a given
span, usually 12".
3. Use roof opening chart (Figure 12) 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
penetrates roof line. Check to see that
proper clearances are maintained. Extend
chimney 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.

Determine ashing to be used with roof open-
ing 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 nailing through
shingles (see Figure 13). DO NOT NAIL

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 open edge of ashing
(see Figure 14). Apply waterproof caulk around
perimeter of collar to provide a proper seal.

CHASE INSTALLATIONS
Instructions for chase installations are includ-
ed with the chase style termination chosen.
In a multiple chase installation, be sure to
provide adequate distance between termi-
nations to prevent smoke spillage from one
termination to another. Terminations must be
separated a minimum of 24" center to center
and stacked at a minimum vertical height dif-
ference of 18" (see Figure 16, page 10).
Note: If a decorative shroud is to be installed,
contact the manufacturer for specications.

10 FOOT RULE
All ue gas outlet chimney terminations must
extend a minimum of 3 feet in height above
highest point where it passes through the roof
and must be at least 2 feet above highest point
of the roof that is within a horizontal distance
of 10 feet (see Figure 17).

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 face
itself. Brick, glass, tile or other noncombustible
materials may overlap 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.

Each brick housing is stamped with a number
(full size bricks are not stamped). These num-
bers will help identify the brick when installing.
It is important to install these bricks exactly as
instructed. Press brick rmly into brick housing
until it snaps. Groove line on side of brick will
come in contact with ange on brick housing.
This secures brick into housing (see Figure
24). Smaller bricks may require a small portion
of furnace cement applied to back of brick to
secure it until grouting has been completed.
Bricks are packaged in separate boxes. Brick
matrixes on pages 12 through 15 show how
bricks are packaged and placed for each size
replace and number of bricks per box. There
are 2 extra full bricks included in Hearth Brick
package. Bricks in brick matrixes are labeled
"I" for ivory and "R" for red.
Install bricks one section at a time starting with
hearth panel followed by the rear panel, left
panel and right panel. It is important to install
the bricks in sequence. Please note, full size

Figure 20 - Grouting Brick
GROUTING INSTRUCTIONS
Material provided:
1 or 2 - 10 lb. bags of cement (depending
on model)
1 or 2 - 10 lb. bags of sand (depending
on model)
Material required:
1 - Piping bag
1 - Joints striker
1 - Heavy duty mixing bucket
1 - Trowel
1. Moisten brick surface with damp sponge
or spray bottle just prior to application.
When bricks are wet, any excess grout
mixture on bricks will easily wipe off.
2. In a heavy duty mixing bucket, pour 7
cups of water. Add 5 lbs. (half of a bag) of
sand and 5 lbs (half of a bag) of cement.
Mix together well using a power drill with
mixing wand attachment.
3. The overall length of piping bag should be
about 16". If the bag is longer than 16",
cut it down to size by removing end with
larger opening. This will make the bag
easier to handle.
4. Put 2 to 3 cups of grout mixture into piping
bag making sure the smaller opening is
downward and over a moist towel to avoid
spilling. Place a wet towel over the bucket
making sure it is directly on the surface of
grout mixture. This will keep the mixture
moist and it will not dry out before use.
5. Begin grouting by first doing a “Filler
Pass”. This is done by lling the joint about
3/4 full with grout mixture. It is important
to work with only 6 bricks at a time so
grout doesn't have time to set up before
striking.
6. Complete a “Finishing Pass” around 6
bricks you just put ller pass around. This
is done by slowly lling in remainder of the
joint with a thick amount of grout mixture.
Mixture should be a little higher than the
brick surface.
7. Using a trowel, remove excess grout mix-
ture by moving trowel in the direction of
the joint. Grout mixture in the joint should
now be ush with brick surface.
8. Using a joint striker, force grout mixture
into joint and sweep back and forth
until grout is smooth and round. If grout
becomes too shallow, add more grout
mixture with piping bag and strike again.
9. Continue procedure around each group of
6 bricks until an entire panel is nished.
10. Using trowel, scrape in direction of joints
to remove any grout that may have col-
lected around bricks during striking. If
desired, take a moist sponge and lightly
sweep over bricks to remove any grout
that may have gotten on bricks. DO NO
PRESS HARD OR RUB IN A CIRCULAR
MOTION. This will press the grout into
brick and turn brick a different color.

replace bottom face surface. Mark hole
centers and remove rail (see Figure 22).
4. Drill 9 - 5/32" diameter holes about 1"
deep directly into bricks using a 5/32"
concrete drill bit (not provided).
5. Place rail back on bricks and align holes.
Secure using 9 concrete screws provided

OPERATION AND MAINTENANCE
GLASS DOORS
Glass doors are optional with 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 26).
A replace equipped with glass doors oper-
ates 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 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 func-
tion 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.

Installing Glass Doors
After spring clips have been installed some
adjustments may be needed. Install the doors
using the following steps:
1. With bi-fold doors completely folded, insert
bottom pivot pin into bottom retaining clip
located at far left and far right side of bot-
tom rail. Swing door to vertical position
making sure top pins slide into top door rail.
Door is installed when top door pin snaps
into spring clip (see Figure 24).
2. Repeat step 1 for remaining door.
If you nd the doors do not close properly or
do not appear level or straight, proceed with
section on door adjustment.
DOOR ADJUSTMENT
Remove doors and slightly loosen upper spring
clips. Replace and fully close doors. Use 1/8"
shims (any material) to level doors. Once proper
setting is achieved, carefully open doors enough
to access top retaining clips with a phillips

IMPORTANT: The glass must be allowed to
warm slowly and evenly. 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,
