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. Modication 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.

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 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 6).

The minimum height of the chimney, measured
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 be-
tween 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).

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 oor-
ing, 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 open-
ing 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 re-
place 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.

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 oor construction in front of the re-
place. Fabricate a hearth extension using a material
which meets the following specications: 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 non-
combustible 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 open-
ing. Combustible materials above 12" and projecting
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

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 as-
sembled 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 re-
place starter. The wire will assure the proper spacing
between the inner and outer pipe sections.
Continue to assemble chimney sections as outlined
above, making sure that both the inner and outer
pipe sections are locked together. When install-
ing 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).

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".

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.

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) 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.

When installing the ashing on a metal roof, it is
required that putty tape be used between the ash-
ing 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.

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 open-
ings like louvered slots or any other opening. When
overlapping with a noncombustible facing material,
use only noncombustible mortar or adhesive.
OPTIONAL GAS LINE
INSTALLATION
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 appropriate
ttings.
1. Remove knockout indentation on refractory or
rebrick wall located above the 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 Figure 18).
2. Remove gas line cover plate located on either
side of replace and pull out insulation from gas
line conduit sleeve. Save insulation for reuse.

OPERATION AND
MAINTENANCE
GUIDELINES

Glass doors are optional with the replace. When
fireplace is in operation, doors must be fully
opened or fully closed position only or a re hazard
may be created (see Figure 24).
A replace equipped with 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 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 fol-
lowed to assure that both the replace and glass door
retain their beauty and function 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.
IMPORTANT: 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.

Cleaning Glass
Clean 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 the re and smoke.
A gas line or gas log lighter may be installed for the
purpose of installing a vented or vent-free deco-
rative 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 requirements for Gas Fired Log
Lighters for Wood Burning Fireplaces, Draft NO.
4 dated August, 1993.
