SAFETY INFORMATION
IMPORTANT: Check local codes
before installing this replace.
Before beginning the installation of the replace,
read these instructions through completely.
• This DESA replace and its components are
safe when installed according to this installation
manual. Unless you use DESA components,
which have been designed and tested for the
replace system, you may cause a re hazard.
• The DESA warranty will be voided by and
DESA disclaims any responsibility for the
following actions.
a. Modication of the replace, components,
doors, air inlet system and damper control.
b. Use of any component part not manufac-
tured or approved by DESA in combination
with a DESA replace system.
Proper installation is the most important step in
ensuring safe and continuous operation of the
replace. Consult the local building codes as to
the particular requirements concerned with the
installation of all factory built replaces.
WARNING: Do not install a
replace insert in this box unless
the manufacturer's instructions
with the insert specically state
this replace has been tested for
use with this insert.
FOR YOUR SAFETY
• Do not store or use gasoline
or any other ammable vapors
or liquids in the vicinity of this
or any other appliance.
• Due to high temperatures, the
appliance should be located
out of trafc and away from
furniture and draperies.
• Do not place clothing or other
ammable materials on or near
the appliance.
• Never leave children unat-
tended when a re is burning
in the replace.
WARNING: Use solid wood
or processed solid fuel relogs
only. When processed wood fuel
re logs are used, do not poke or
stir the logs while they are burn-
ing. Use only re logs that have
been evaluated for the application
in replace and refer to re log
warnings and caution markings
on packaging prior to use.

SELECTING LOCATION
To determine the safest and most efcient 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 8).
MINIMUM CLEARANCE TO
COMBUSTIBLES
Back and sides of replace 3/4" minimum*
Floor** 0" minimum
Perpendicular wall to opening 12" minimum
Top spacers 0" minimum
Mantel clearances
Chimney outer pipe surface 1" minimum
* 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 for
Residential Installation
The minimum height of the chimney, measured
from the base of the replace to the ue gas outlet
of the termination, is 14.5 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 18,
page 11).
Minimum/Maximum Chimney Height for
Outdoor Installation
The minimum height of the chimney, measured
from the base of the replace to the ue gas outlet
of the termination, is 7 1/2 feet (minimum of 4 feet
of chimney pipe sections required for outdoor
installation).

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 other than wood ooring, the replace must be installed upon a
metal or wood panel extending the full width
and depth of the replace.
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 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 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.

DRAIN PAN (DP36)
For outdoor installations, the replace 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 the replace within the replace
enclosure (see Accessories on page 16).
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. Fabricate a hearth extension using a material
which meets the following specications: 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 fireplace opening. Combustible materials
above 12" and projecting more than 11/2" 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.

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.

CHIMNEY PIPE
The DESA 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 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".
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. 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 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.
