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 Figure 2).
2. Consider a location where the heat output
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. If an outside air kit is to be installed, ac-
cessibility to outside combustion air must
be considered. This can also be achieved
through a vented crawl space in some
cases (see Optional Outside Air Kit on
page 6).
The typical installation for a (V)PN36-A is a
projected installation which allows you to ex-
tend the replace any distance into the room.
A projection may be ideal for a new addition
on an existing, nished wall.

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 upon
a metal or wood panel extending full width
and depth of replace.
3. Set replace directly in front of opening
and slide unit back until nailing anges
touch side framing.
4. Check the 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
(see Figure 7). 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 (see
Figure 6). The ember protector should be
made of galvanized sheet metal (28 gauge
minimum) to prevent corrosion.
6. Using screws or nails, secure replace to
the framing through anges located on
sides of the replace (see Figure 8).

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 replace (see Figure 9, page 6).
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 manufacturer or supplier of
noncombustible material.
If hearth extension is to be raised, a “Z” type
ember protector must be used (see Figure 6
and Figure 10, page 6)

Woodwork such as wood trims, mantels or
any other combustible material projecting from
the front face must not be placed within 9" of
replace opening.
Combustible materials above and projecting
more than 1 1/2" from the replace front face
(see Figure 11) must not be placed less than 12"
from effective opening of the replace (NFPA
STD 211, Sec. 7-3.3.3).
Mantels or any other combustible material
may also come up to the side edge of the
black metal face of the replace only if the
projection from the front face falls within limits
shown in Figure 12.

The pipe sections must be assembled inde-
pendently 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.
Continue to assemble chimney sections as
outlined above, making sure that both the
inner and outer pipe sections are locked to-
gether. 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 lock-
ing. The chimney will not come apart if prop-
erly locked. It is not necessary to add screws
to keep the chimney together (exception, see
Figure 17, page 8).

The DESA chimney is a snap-lock, double-
wall pipe. It consists of a stainless steel inner
ue pipe(s), a galvanized outer pipe and a
wire spacer.
Each section of pipe comes in lengths of 12",
18" 36" and 48". The actual lineal gain for
each is measured after each section is fully
connected. Lineal gain is the actual measur-
able length of a part after two or more parts
are connected.

Chimney weight above offset rests on return
elbow. Straps must be securely nailed to raf-
ters or joists (see Figure 15, page 8).
To achieve desired offset, you may install
combinations of 12", 18", 36" and 48" length
of double wall pipe (see offset chart and
Figure 16, page 8).
The chimney support section is a 4" strap
and 12" length of pipe. A chimney support is
required every 30 feet above replace after a
straight chimney run or above a return elbow
after a straight chimney run (see Figure 17,
page 8). This support is designed to relieve
the extra weight load on replace and elbows
when high chimneys are installed.

Firestop spacers are required at each point
where the chimney penetrates a oor or ceiling
joist space. Their purpose is to establish and
maintain the required clearance between the
chimney and the combustible materials.
When penetrating a oor or ceiling at an angle,
use restop spacer number 30 FS-10D (see
Replacement and Accessory Parts, page 15).
When the pipe passes through a framed open-
ing into a living space above, the restop must
be placed onto the ceiling from below as shown
in Figure 19, page 9. When the pipe passes
through a framed opening into an attic space
above, the restop must be placed on the attic
oor as shown in Figure 20, page 9.

All chimney terminations must extend a mini-
mum of 3 feet above the highest point where it
passes through the roof and must be at least 2
feet above roof with a 10 foot horizontal span
(see Figure 21).
IMPORTANT: If an exposed portion of chim-
ney is greater than 4 feet above the rooine,
use support wires to keep chimney secure.
Support wires may be attached to outer pipe
of chimney with screws, if screws do not
penetrate inner ue pipe.

HEIGHT
The minimum height of the chimney (mea-
sured from the base of the replace to the ue
gas outlet-end of pipe) is 16 feet for a straight
run, 16 feet minimum for a run with 1 elbow set
and 25 feet minimum for a run with 2 elbow
sets. (A set consists of one starter elbow and
one return elbow.)
Uncommon circumstances such as neigh-
boring hills, tall trees, or strong wind areas
can cause down drafts in chimney system.
In such cases, going beyond the minimum
recommended height would be preferable to
provide a better draw.
The replace height approved for any chim-
ney run with this replace system is 40 feet
measured from bottom of replace to ue
outlet-end of pipe (see Figure 22).

To maintain a 1" clearance to pipe on a roof with
a pitch, a rectangular opening must be cut.
1. Determine the 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 roof rafters.
3. Use roof opening chart (Figure 23) 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 end
penetrates roof line. Check to see that
proper clearances are maintained. Extend
chimney by adding sections of double wall
pipe until pipe is minimum of 30" above
highest point of roof cutout. Termination
and chimney must extend a minimum of
36" above highest point where it passes
through the roof.

any case, refer to the installation instructions
supplied with the termination.
Terminations approved for this replace are
RTL-12DM, which can be used for ashing
or chase and STL-12DM for chase style ter-
mination only. Figure 26, page 11, shows an
