FRAMING AND INSTALLING THE FIREPLACE
STEP 1: Frame the opening for the fireplace using the
dimensions shown in figures 1 & 2.
STEP 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.
STEP 3: Set the fireplace directly in front of this opening and
slide the unit back until the nailing flanges touch the side
framing.
STEP 4: Check the level of the fireplace and shim with sheet
metal if necessary.
STEP 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-gage
minimum) to prevent corrosion.
STEP 6: Using screws or nails, secure the fireplace to the
framing through flanges located on the sides of the fireplace.
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
non-combustible, 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:
Thermal conductivity “K” of materials can be obtained from
the manufacturer or supplier of the non-combustible material.
If the hearth extension is to be covered, use non-combustible
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 non-combustible material
(see figure 3).
OPTIONAL OUTSIDE AIR KIT (MODEL AK4 / AK4F)
The installation of an outside air kit should be performed
during the rough framing of the fireplace due to the nature of
its location. Outside combustion air is accessed through a
vented crawl space (AK4F) or through a sidewall (AK4). See
page 10, figure 23 for instructions on how to operate the air
kit.
WARNING Hearth extension is to be installed onl
y
as illustrated.

FAN/BLOWER KIT ASSEMBLY
Fan or blower kit is optional (for circulating models only) with
this fireplace. Use of blowers or fans other than manufactured
by DESA voids the warranty. Fan is operated by pressing the
rocker switch (see figure 5a) in the lower right hand corner of
the fireplace face. Blower is operated by turning the control
knob (not shown).
Fan/blower kit electrical connections are made through the
electrical cover plate on the side of the fireplace as shown in
figure 5a.
WIRING INSTRUCTIONS
i. Remove electrical cover plate (with electrical
bushing) from the fireplace by removing the two
sheet metal screws as shown in figure 5a.
ii. Slide power source wiring through the electrical
bushing opening and electrical cover plate and make
all the necessary connections.
iii. Slide all wiring connections in the electrical housing
as shown in figure 5b.
iv. Secure the electrical cover plate with screws
previously removed.
NOTE: Electrical housing and cover plate have sharp edges,
wear protective gloves.
CHIMNEY PIPE
The DESA chimney system consists of 12, 18, 24, 36 and 48
inch, 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).
ASSEMBLY AND INSTALLATION OF THE DOUBLE
WALL CHIMNEY SYSTEM
Each double wall chimney section is consist 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.
For Canada, use chimney parts designated “HT”
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 page 5 figure 9).
INSTRUCTIONS WHEN ELBOW OFFSET (30E-8DM)
OF CHIMNEY IS NEEDED
1. To achieve desired offset, you may install combinations of
12”, 18”, 24”, 36” and 48” length of double wall pipe (SEE
SINGLE OFFSET CHARTAND 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 & b).
3. Maximum length of pipe between supports (return elbow
or 12S-8DM) is 6’ of angle run. Maximum of two (2) 6’ angle
run sections per chimney system (see figure 7).
WARNING: The opening in the collar around the
chimney at the top of the fireplace must not be obstructed.
N
ever use blown insulation to fill the chimne
y
enclosure.

*For systems with two elbow sets, the minimum height is 22
feet. The maximum height for any system is 50 feet.
OFFSET CHART (22-50 FT. SYSTEM HEIGHT)
FIRESTOP SPACERS (FS-8DM)
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.

PENETRATING THE ROOF
To maintain a 2-inch clearance to the pipe on a roof with a
pitch, a rectangular opening must be cut.
STEP 1: Determine the center point through which the pipe
will penetrate the roof.
STEP 2: Determine the center point of the roof. Pitch is the
distance the roof drops over a given span, usually 12 inches.
A 6/12 pitch means that the roof drops 6 inches for each 12
inches one measure horizontally down from the roof rafters.
STEP 3: Use the roof opening chart (figure 12) to determine
the correct opening length and flashing required.
STEP 4: Remove the shingles around the opening measured
and cut out this section.
STEP 5: Add the next sections of the pipe until the end
penetrates the roofline. Check to see that the proper
clearances are maintained. Extend chimney by adding
sections of double wall pipe until pipe is a minimum of 30
inches above the highest point of the roof cutout. Termination
and chimney must extend a minimum of 36 inches above the
highest point where it passes through roof.
FLASHING INSTALLATION (V6F-8DM or V12F-8DM)
Determine the flashing to be used with the roof opening chart.
Slide flashing over pipe until base is flat against roof. Replace
as many shingles as needed to cover exposed area and flashing
base. Secure in position by nailing through shingles (see
figure 13).
DO NOT NAIL THROUGH FLASHING CONE.
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 ¾” 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 proper seal.
STORM COLLAR INSTALLATION (SC1 or SC2)
Place storm collar over pipe and slide down until it is snug
against the open edge of the flashing (see figure 14). Use SC1
for all round terminations and SC2 for all terminations with
slip sections. Apply waterproof caulk around the perimeter of
the collar to provide a proper seal.

TERMINATIONS / SPARK ARRESTOR
The fireplace system must be terminated with the listed round
top or chase terminations. In any case, refer to the installation
instructions supplied with the termination. The terminations
approved for this fireplace are the RT-8DM and RTL-8DM
that can be used for flashing or chase and ET-8DM, ETO-
8DM, ETL-8DM and ETLO-8DM for chase style termination
only. Figure 15 shows an RTL-8DM round top termination.
Terminations with 16” slip pipe sections are available. The
RTT-8DM and RTTL-8DM are approved for flashing
installations. When needed, these adjustable terminations may
be used in combination with the pipe assembly to achieve the
correct chimney height.
NOTE: In the rare instance there is a problem with the side
driven rain or wind or the chimney is not drafting properly, an
ADS-8DM Anti Draft Shield can be used with round
terminations.
*NOTE: If a decorative shroud is to be installed, contact the
manufacturer for specifications.
CHASE INSTALLATIONS
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 inches,
center to center and stacked at vertical height difference of 18
inches (see figure 16).
All flue gas outlet of chimney termination must extend a
minimum of 3 feet in height above the highest point where it
passes through the roof and must be at least 2 feet above the
highest point of the roof that is within a horizontal distance of
10 feet (see figure 17).
FINISHING THE FIREPLACE
Combustible materials, such as wallboard, gypsum board,
sheet rock, drywall, plywood, etc. may make direct contact
with sides and top periphery of the fireplace face. It is
important that combustible materials do not overlap the face
itself. Brick, glass, tile or other non-combustible materials
may overlap the front face provided they do not obstruct
essential openings like louvered slots or any other opening.
When overlapping with a non-combustible facing material,
use only non-combustible mortar or adhesive.
MANTELS
A mantel may be installed if desired (see figures 18 & 18a),
Woodwork such as wood trims, mantels, or any other
combustible material projecting from the front face must not
be placed within 12 inches of the fireplace opening (and
within 9 inches of the top louver opening). Combustible
materials above 12 inches and projecting more than 1-1/2
inches from the fireplace must not be placed less than 12
inches from the top opening of the fireplace (NFPA STD 211,
Sec. 7-3.3.3).
Figure 17 10-FOOT RULE
CAUTION: Do not seal openings on the rooftop flashing.

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 19.
OPERATING GUIDELINES AND MAINTENANCE
INSTRUCTIONS
GLASS DOORS
Glass doors are optional with the fireplace. When the
fireplace is in operation, doors must in FULLY OPENED or
FULLY CLOSED position only or a fire hazard may be
created (see figure 20).
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 the combustion air gate is not completely open.
The following tips should be followed to assure that both the
fireplace and the glass door retain their beauty and function
properly. Both the flue damper and the glass doors must be
fully opened before starting the fire. This will provide
sufficient combustion air and maintain safe temperatures in
the firebox.
IMPORTANT: The glass must be allowed to warm slowly
and evenly. The tempered glass will withstand a gradual
temperature rise to 550 degrees Fahrenheit, 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.
CLEANING THE GLASS
Clean the glass with any commercial glass cleaner or soap and
water. Do not use any abrasive material to clean the glass. Do
not clean the glass with any cool water if the glass is still hot
from the fire and smoke.
Figure 20 GLASS DOORS
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 an
d
flame out of the fireplace opening creating risks of bot
h
fire and smoke.
