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

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.
