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 6).

Residential Installation
The minimum height of the chimney, mea-
sured 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).

Outdoor Installation
The minimum height of the chimney, mea-
sured from the base of the replace to the
ue gas outlet of the termination, is 7 1/2feet
(minimum of 4 feet of chimney pipe sections
required for outdoor installation).

1. Frame opening for fireplace using the
dimensions 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, the replace must be installed
upon a metal or wood panel extending
the 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 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 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 replace a
minimum of 1 1/2". The ember protector
should be made of galvanized sheet metal
(28 gauge minimum) to prevent corro-
sion.
6. Using screws or nails, secure replace to
framing through anges located on sides
of replace.

DRAIN PAN (DP36)
For outdoor installations, the replace enclo-
sure 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 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).

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 11/2" from the fireplace
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.

pipe segments, planned for maximum adapt-
ability 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".

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. 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 chim-
ney 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).

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 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 offset and
return must be secured with two screws
on outer pipe only (see Figure 9, page 8).
Do not penetrate inner stainless.

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 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". A 6/12 pitch means that the
roof drops 6" for each 12" one measure
horizontally down from the roof rafters.
3. Use roof opening chart (Figure 12, page
9) to determine the correct opening length
and ashing required.
4. Remove the shingles around opening
measured. Cut out this section.
5. Add next sections of pipe until end pen-
etrates 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 the
ashing and 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 screw holes. A roof coating must also be
applied around perimeter of ashing to provide

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 24", center

Glass doors are optional with the replace.
When the replace is in operation, doors
must be fully opened or fully closed position
only or a re hazard may be created (see
Figure 21).
Figure 21 - Glass Doors

www.desatech.com
111026-01F 13
A replace equipped with glass doors oper-
ates mush differently than a replace with an
open front. A replace with glass doors has a
limited amount of air for combustion. Exces-
sive 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 as-
sure 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 sufcient combustion air and maintain
safe temperatures in the 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.
