hazard.
• The DESA Heating, LLC warranty will be
voided by and DESA Heating, LLC dis-
claims any responsibility for the following
actions.
a. Modification of the fireplace, com-
ponents, doors, air inlet system and
damper control.
b. Use of any component part not manu-
factured or approved by DESA Heat-
ing, LLC in combination with a DESA

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,
page 6).

The minimum height of chimney, measured
from base of replace to ue gas outlet of
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 replace,
chimney sections and height of termination
assembly at level of the ue gas outlet (see
Figure 15, page 9).

1. Frame opening for replace using dimen-
sions 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, replace must be installed on 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 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. 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 replace to
framing through anges located on sides
of replace.

116010-01E 5
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 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 3).

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 top opening of replace (NFPA STD 211,
Sec. 7-3.3.3).
Mantels or any other combustible mate-
rial also may come up to side edge of black
metal face of replace as long as projection
from front face fall within the limit shown in

The 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 consider-
ation (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".

Installation of an outside air kit should be
performed during rough framing of replace
due to the nature of it's location. Outside com-

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 chim-
ney is installed. When connecting chimney
directly to replace, inner ue pipe section
must be installed rst with lanced side up.
The 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 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 chim-
ney together, it is important to assure the joint
between chimney sections is locked. Check
by pulling chimney upward after locking. The
chimney will not come apart if properly locked. It
is not necessary to add screws to keep chimney
together (exception, see Figure 7).

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 7).
2. Chimney weight above offset rests on
return elbow. Straps must be securely
nailed to rafters or joists (see Figure 8,
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 9, page 8).
4. All pipe connections between offset and
return must be secured with two screws
on outer pipe only (see Figure 7). Do not
penetrate inner stainless.

Firestop spacers are required at each point
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 double wall
pipe passes through a framed opening into
an attic space, restop must be placed into
attic oor as shown in Figure 11.

To maintain a 1" clearance to the pipe on a
roof with a pitch, a rectangular opening must
be cut.
1. Determine the 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 the
roof drops 6" for each 12" one measure
horizontally down from roof rafters.
3. Use roof opening chart (Figure 12, page
9) 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 the end pen-
etrates the roof line. Check to see that the
proper clearances are maintained. Extend
chimney by adding sections of double wall
pipe until pipe is minimum of 30" above the
highest point of the roof cutout. Termination
and chimney must extend a minimum of
36" above the highest point where it passes
through the 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 ap-
plied around perimeter of ashing to provide
a proper seal.

Combustible materials, such as wallboard,
gypsum board, sheet rock, drywall, plywood,
etc. may make direct contact with sides and
top around replace face. It is important that
combustible materials do not overlap the 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.

Instructions for chase installations are includ-
ed with 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 difference of 18"
(see Figure 16).
Note: If a decorative shroud is to be installed,
contact the manufacturer for specications.
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.
Use only a 1/2" black iron pipe and appropri-
ate ttings.
1. Remove knockout indentation on refractory
or rebrick wall located above refractory
hearth oor. The 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 (see Fig-
ure 18).
