Fireplace Installation Framing
selecting location
To determine the safest and most efficient location
for the fireplace, 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 fireplace 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 fireplace
(see Optional Outside Air Kit on page 8).

1. Frame the opening for the fireplace using the
dimensions shown in Figures 1 and 2.
2. If the fireplace is to be installed directly on
carpeting, tile (other than ceramic) or any
combustible material other than wood flooring, the fireplace must be installed upon a
metal or wood panel extending the full width
and depth of the fireplace.
3. Set the fireplace directly in front of this opening and slide the unit back until the nailing
flanges touch the side framing.
4. Check the level of the fireplace and shim with
sheet metal if necessary.
5. Before securing fireplace to prepared framing,
the ember protector (provided) must be placed
between the hearth extension (not supplied)
and under the bottom front edge of the fireplace to protect against glowing embers falling
through. If the fireplace is to be installed on
a raised platform, a Z-type ember protector
(not supplied) must be fabricated to fit your
required platform height. The ember protector
should extend under the fireplace 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 fireplace to
the framing through flanges located on the
sides of the fireplace.
WARNING: Do not pack required air spaces with insulation
or other materials.
Minimum/Maximum Chimney Height
The minimum height of the chimney, measured
from the base of the fireplace to the flue gas outlet
of the termination, is 16 feet for straight flue or a
flue 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 fireplace, chimney sections and the height of the termination assembly
at the level of the flue gas outlet (see Figure 15,
page 11).

Hearth Extension
A hearth extension projecting a minimum of 20"
in front of and a minimum of 12" beyond each
side of the fireplace opening is required to protect
combustible floor construction in front of the fireplace. Fabricate a hearth extension using a material
which meets the following specifications: 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 fiber,
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
fireplace frame and hearth extension with a noncombustible material (see Figure 3).
WARNING: Hearth extension
is to be installed only as shown
in 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" (GM36) or 18"
(GM42/50) of the fireplace opening. Combustible
materials above 12" (GM36) or 18" (GM42/50)
and projecting more than 1 1/2" from the fireplace
must not be placed less than 15" (GM36) or 21"
(GM42/50) from the top opening of the fireplace
(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 fireplace just as long as the projection
from the front face fall within the limit shown in
Figure 4.

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 fitting 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 fireplace must not be
obstructed. Never use blown insulation to fill the chimney enclosure.

Assembly and installation of
double wall chimney system
Each double wall chimney section consists of a
galvanized outer pipe, a stainless steel inner flue
pipe and a wire spacer. The pipe sections must be assembled independently as the chimney is installed.
When connecting chimney directly to the fireplace,
the inner flue pipe section must be installed first
with the lanced side up. The outer pipe section can
then be installed over the flue pipe section with the
hemmed end up. Press down on each pipe section
until the lances securely engage the hem on the fireplace 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 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 10).

Penetrating the roof
To maintain a 1" (GM36) or 2" (GM42/GM50)
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
flashing required.

1" Min.
Firestop spacers are required at each point where
the chimney penetrates a floor 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 firestop must be placed onto
the ceiling from below as shown in Figure 10.
They also provide complete separation from one floor
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 firestop must
be placed into an attic floor as shown in Figure 11.

Installing Flashing on a Metal Roof
When installing the flashing on a metal roof, it is
required that putty tape be used between the flashing and the roof. The flashing 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 flashing to provide a

finishing the fireplace
Combustible materials, such as wallboard, gypsum
board, sheet rock, drywall, plywood, etc. may make
direct contact with sides and top around the fireplace
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 openings 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 qualified service person.
Note: Before you proceed, make sure your gas
supply is turned off.
Use only a 1/2" black iron pipe and appropriate
fittings.
1. Remove knockout indentation on refractory or
firebrick wall located above the refractory hearth
floor. The knockout indentation must be firmly
tapped with any solid object such as a 1/2" dowel
until it is released. Remove fragmented portions
of refractory (see Figure 18, page 13).
2. Remove gas line cover plate located on either
side of fireplace and pull out insulation from gas
line conduit sleeve. Save insulation for reuse.
Replace screws.

Brick Installation
Installing Brick "S"
Use brick “S” if an optional gas line is installed.
Mount brick “S” as shown in Figure 21. It is
important that the knockout hole is in its proper
location. The knockout hole on brick “S” should
align with the hole on the brick housing.
Installation of brick should be
done after the fireplace is placed
in a permanent location.
The brick housing panels are already installed in
the firebox. Each housing is stamped with a letter
(full size bricks are not stamped). These letters will
help identify the brick when installing. It is important to install these bricks exactly as instructed.
Press the brick firmly into the brick housing until
it snaps. The groove line on the side of the brick
will come in contact with the flange on the brick
housing. This secures the brick into the housing.
See Figure 20.

Installing Z-shaped Grate

Before grouting the bricks, locate the z-shaped
grate retainer brackets on top of the hearth bricks as
shown in Figure 22. Position the retainer brackets
at 8 3/4" apart from center to center of notch.

Grouting instructions
Material provided:
2 - 9 lb. bags of cement
2 - 9 lb. bags of sand
Material required:
1 - Piping bag
1 - Joints striker
1 - Heavy duty mixing bucket
1 - Trowel
1. Moisten brick surface with a damp sponge or a
spray bottle just prior to application. When the
bricks are wet, any excess grout mixture that
might have gotten onto the brick will easily
wipe off.
2. In a heavy duty mixing bucket, pour seven (7)
cups of water in first, then add in 4.5 lbs. (half
of a bag) of sand and 4.5 lbs (half of a bag) of
cement. Mix together well using a power drill
with a mixing wand attachment.
3. The overall length of piping bag should be
about 16". If the bag is longer than 16", cut
it down to size by removing end with larger
opening. This will make the bag easier to
handle.
112435-01M
4. Put 2 to 3 cups of grout mixture into piping bag
making sure the smaller opening is downward
and over a moist towel to avoid spilling. Place
a wet towel over the bucket making sure it is
directly on the surface of grout mixture. This
will keep the mixture moist and it will not dry
out before use.
5. Begin grouting by first doing a “Filler Pass”.
This is done by filling the joint about 3/4 full
with grout mixture. It is important to work
with only 6 bricks at a time so grout doesn't
have time to set up before striking.
6. Complete a “Finishing Pass” around 6 bricks
you just put filler pass around. This is done by
slowly filling in remainder of the joint with a
thick amount of grout mixture. Mixture should
be a little higher than the brick surface.
7. Using a trowel, remove excess grout mixture
by moving trowel in the direction of the joint.
Grout mixture in the joint should now be flush
with brick surface.
8. Using a Joint Striker, force grout mixture into
joint and sweep back and forth until grout is
smooth and round. If grout becomes too shallow, add more grout mixture with piping bag
and strike again.
9. Continue procedure around each group of 6
bricks until an entire panel is finished.
10. Using trowel, scrape in direction of joints to
remove any grout that may have collected
around bricks during striking. If desired, take
a moist sponge and lightly sweep over bricks
to remove any grout that may have gotten on
bricks. DO NO PRESS HARD OR RUB IN
A CIRCULAR MOTION. This will press
the grout into brick and turn brick a different
color.
Allow 72 hours before operating
fireplace.

Installing glass doors
Spring clips have been installed but some adjustments may be needed. Install the doors using the
following steps:
1. With bi-fold doors completely folded, insert
bottom pivot pin into pivot hole located near
bottom corner of front face opening and swing
door to vertical position making sure top pins
slide into door track. Door is installed when
top door pin snaps into spring clip.
2. Repeat step 1 for remaining door.
If you find the doors do not close properly or do
not appear level or straight, proceed with section
on door adjustment,

Door Adjustment
Remove doors and slightly loosen lower pivot clips
and upper spring clips. Replace doors and fully close
them. Use 1/8" shims (any material) to level doors.
Once proper setting is achieved, carefully open doors
enough so that you can access spring clips with a phillips screwdriver. Tighten screws. See Figure 29.
Glass doors are optional with the fireplace. When
fireplace is in operation, doors must be fully
opened or fully closed position only or a fire hazard
may be created (see Figure 30).
A fireplace equipped with glass doors operates
much differently than a fireplace with an open
front. A fireplace with glass doors has a limited
amount of air for combustion.
Excessive heat within the fireplace can result if
too large a fire is built or if combustion air gate is
not completely open. The following tips should
be followed to assure that both the fireplace and
glass door retain their beauty and function properly. Both the flue damper and glass doors must
be fully opened before starting fire. This will
provide sufficient combustion air and maintain
safe temperatures in firebox.
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 fire 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 fire
and should not be burned in this fireplace. Always
keep the fire well back from the doors and never
allow flames to contact the glass.
WARNING: Fireplaces
equipped with glass doors
should be operated only with
doors fully opened or doors fully
closed. Doors, if left partly open,
may draw gas and flame out of
the fireplace opening creating
risks of both fire and smoke.

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 fire 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 requirements for Gas Fired Log
Lighters for Wood Burning Fireplaces, Draft NO.
4 dated August, 1993.
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 fireplace.
