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.

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-

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.

111026-01C6
VENTING INSTALLATION
Continued
Continue to assemble chimney sections as outlined,
making sure that both the inner and outer pipe sections are locked together. 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 if properly locked. It is not necessary to add screws to
keep the chimney together (exception - see Figure
9, page 8).
USING ELBOW OFFSETS (30E-8DM)
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 & b on page 8).
3. Maximum length of pipe between supports
(return elbow or 12S-8DM) is 6' of angle run.
Maximum of two 6' angle run sections per
chimney system (see Figure 7).
4. All pipe connections between the offset and
return must be secured with two screws on the
outer pipe only (see Figure 9, page 8). Do not
penetrate the inner stainless.

FIRESTOP SPACERS (V3600FS-8DM)
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 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 THE ROOF
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 the
pipe will penetrate the roof.
2. Determine the 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" one measure
horizontally down from the roof rafters.
3. Use the roof opening chart (Figure 12, page
9) to determine the correct opening length and
ashing required.
4. Remove the shingles around the opening
measured. Cut out this section.
5. Add the next sections of the pipe until the
end penetrates 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.

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 leakage through the screw holes. A roof
coating must also be applied around the perimeter of
the ashing to provide a proper seal.

Note: In the rare instance there is a problem with
the side driven rain or wind or the chimney is
not drafting properly, an ADS-8DM (Anti-Draft
Shield) can be used with round terminations.
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

Continued
A replace equipped with glass doors operates
mush 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 the combustion air gate is not completely open.
The following tips should be followed to assure
that both the replace and the glass door retain
their beauty and function properly. Both the ue
damper and the glass doors must be fully opened
before starting the re. This will provide sufcient
combustion air and maintain safe temperatures in
the rebox.
IMPO RTANT: 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.
WA R N ING: Firep l a c e s
equi pped wi th g lass do ors
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.
If you wish to install an unvented (vent-free) gas
log set, only unvented gas log sets which have been
found to comply with the standard for unvented
room heaters, ANSI Z21.11.2 are to be installed
in this replace.
OUTSIDE AIR AND DAMPER
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 into the left of the
keyway slot will free the damper blade to automatically open. Pushing the handle in to the right will
lock the damper blade closed (see Figure 22).
The outside air kit handle is located at the left hand
side of the replace (see Figure 22). Pulling the
handle out will free the outside air door to open.
Pushing the handle in will lock the door closed.
WARNING: Risk of re! Replace
grate with DESA model 111100-01
only. This grate has been designed
to keep the operation of your replace safe and efcient.
For further operating guidelines, instructions and
warranty information, please refer to your homeowner's guide or contact your authorized dealer.

Cleaning the Glass
Clean the glass with any commercial glass cleaner
or soap and water. Do not use any abrasive material to clean the glass. Do not clean the glass with
any cool water is the glass is still hot from the
re and smoke.
A gas line or gas log lighter may be installed for the
purpose of installing a vented or vent-free decorative
gas appliance incorporating an automatic shutoff device and complying with the Standard for Decorative
Gas Appliances for Installation in Vented Fireplaces,
ANSI Z21.60 or American Gas Association draft re-
quirements for Gas Fired Log Lighters for Wood Burning Fireplaces, Draft NO. 4 dated August, 1993.
