General Venting
These models are approved for use with DESA
58 Series, rigid type direct vent pipe as supplied
by DESA or with approved types of flexible vent
pipe (not supplied) when appropriate sized for an
8" outer and 5" inner diameter application.
Your fireplace is approved to be vented either
through the side wall, or vertically using the following guidelines:
• Only use DESA supplied or approved types
of venting components or kits. Do not mix
different types of vent components, modify
vent components or custom fabricate vent
components for use in any one installation.
• Minimum clearance between vent pipes and
combustible materials is 1", except where stated
otherwise.
• Combustible material may be flush with the top
front of fireplace with a maximum thickness
of 3/4".
• Do not recess venting terminals into a wall
or siding.
• Do not install vent terminals below grade level.
Maintain a minimum height of 12" above snow
line.
• Do not terminate venting system into an attic
or garage.
• If using a venting configuration of only horizontal venting with no vertical run, a 1/4" rise
for every 12" of run toward the termination is
required.
56131-F
• There must not be any obstruction such as
bushes, garden sheds, fences, decks, or utility buildings within 24" from the front of the
termination cap.
• Do not locate termination cap where excessive
snow or ice build up may occur. Be sure to clear
vent termination area after snow falls to prevent
accidental blockage of venting system. When
using snow blowers, do not direct snow towards
vent termination area.
Vent Termination Clearances
The final position of your appliance depends on
the location of the vent termination in relation to
the clearances that must be observed as shown in
Figure 14, page 10.
You may avoid extra framing by positioning your
fireplace against an already existing framing member. The back of the fireplace may be positioned
directly against a combustible wall.

Venting Installation
Instructions
WARNING: Read all instructions completely and thoroughly
before attempting installation.
Failure to do so could result in
serious injury, property damage
or loss of life.
WARNING: Seal all connections with high temperature
silicone every time a vent connection is made. Before joining
elbows or pipes, apply a bead
of high temperature silicone
sealant to the male end of the
elbow or pipe. High temperature
silicone must also be used to reseal any connections after maintenance to venting system.
NOTICE: Failure to follow these instructions will void the warranty.
NOTICE: Do not seal termination
cap to vent pipe. Cap must be
removable for vent inspection
and maintenance.
Installation Precautions
Consult local building codes before beginning the
installation. The installer must make sure to select
the proper vent system for installation. Before
installing vent kit, the installer must read this
fireplace manual and vent kit instructions.
Only a qualified service person should install
venting system. The installer must follow these
safety rules:
• Wear gloves and safety glasses for protection
• Use extreme caution when using ladders or
when on roof tops
• Be aware of electrical wiring locations in walls
and ceilings
The following actions will void the warranty on
your venting system:
• Installation of any damaged venting component
• Unauthorized modification of the venting system
• Installation of any component part not manufactured or approved by DESA
• Installation other than as instructed by these
instructions
WARNING: This gas fireplace
and vent assembly must be
vented directly to the outside. The
venting system must NEVER be
attached to a chimney serving a
separate solid fuel burning appliance. Each gas appliance must
use a separate vent system. Do
not use common vent systems.
WARNING: Horizontal sections of this vent system require
a minimum clearance of 2" from
the top of the pipe and 1" minimum to the sides and bottom.
Vertical sections of this system
require a minimum of 1" clearance to combustible materials
on all sides of the pipe.
INSTALLATION PLANNING
There are two basic types of direct-vent installation:
• Horizontal Termination
• Vertical Termination
It is important to select the proper length of vent
pipe for the type of termination you choose. It is
also important to note the wall thickness.
For Horizontal Termination: Select the amount
of vertical rise desired. The horizontal run of
venting must have 1/4" rise for every 12" of run
towards the termination.
WARNING: Never run the
vent downward as this may
cause excessive temperatures
which could cause a fire.
You may use one or two 90° elbows in this vent
configuration. See Horizontal Termination Configurations on page 15.
56131-F
www.desatech.com
11
Venting Installation
Instructions
Continued
For Vertical Termination: Measure the distance
from the fireplace flue outlet to the ceiling. Add
the ceiling thickness, the vertical rise in an attic or
second story, and allow for sufficient vent height
above the roof line. You may use one or two 90°
elbows in this vent configuration. See Vertical
Termination Configurations on page 16.
Note: You may use two 45° elbows in place of a
90° elbow. You must follow rise to run ratios when
using 45° elbows.
For two-story applications, firestops are required at
each floor level. If an offset is needed in the attic,
additional pipe and elbows will be required.
You may use a chase with a vent termination with
exposed pipe on the exterior of the house. See
Installing Vent System in a Chase.
Your DESA direct-vent fireplace has been tested
for a minimum 3' rise with a maximum 11" wall
thickness. Any horizontal application longer than
12" must provide a minimum of one (1) foot of
vertical rise for every three (3) feet of horizontal run.
The maximum horizontal run is 20' with 8' vertical
rise (see Installation for Horizontal Termination).
The maximum vertical run is 30' (see Installation
for Vertical Termination, page 16).
Installing Vent System in a Chase
A chase is a vertical box-like structure built to
enclose venting that runs along the outside of a
building.
NOTICE: Treatment of firestops
and construction of the chase
may vary from building type to
building type. These instructions are not substitutes for the
requirements of local building
codes. You must follow all local
building codes.
Note: When installing in a chase, you should
insulate the chase as you would the outside walls
of your home. This is especially important in
cold climates. Minimum clearance between vent
pipes and combustible materials such as insulation is 1".
After framing the chase (see Framing on page 7)
install the vent system by following the installation instructions.
12
installation for horizontal
termination
1. Determine the route your horizontal venting
will take. Note: The location of the horizontal
vent termination on the exterior wall must
meet all local and national building codes and
must not be blocked or obstructed.
WARNING: Do not recess
vent terminal into a wall or siding. This is a fire hazard.
Snorkel terminations are available for terminations requiring a vertical rise on the exterior of
the building (see Figures 15 and 16). Snorkel
kits are available for rigid pipe applications
only to provide a 14" rise and a 36" rise (see
page 19). Follow the same installation procedures used for standard horizontal terminations.
If installing the snorkel termination to raise the
vent termination from below grade level such
as in a basement installation, you must provide
proper drainage to prevent water from entering
the snorkel termination (see Figure 16). Do not
back fill around the snorkel termination.

2. Rigid vent pipes and fittings have special
twist-lock connections. Assemble the desired
combination of pipe and elbows to the appliance adaptor with pipe seams oriented towards
the wall or floor.
Twist-lock Procedure: The female ends of the
pipes and fittings have four locking lugs (indentations). These lugs will slide straight into
matching slots on the male ends of adjacent
pipes and fittings. (All connections must be
sealed with high temperature silicone sealant
as specified in the second warning statement
on page 11.) Push the pipe sections together
and twist one section clockwise approximately
one-quarter turn until the sections are fully
locked. See Figure 17. Note: Horizontal runs
of vent must be supported every three feet. Use
wall straps for this purpose.
3. Attach vent pipe assembly to the fireplace using
twist lock connections for rigid pipe or clamp
method for flex pipe. Set fireplace in front of
its permanent location to insure minimum
clearances. Mark the wall for a 10 3/4" square
hole (for noncombustible material such as
masonry block or concrete, a 8 1/2" diameter
hole is acceptable). See Figure 18. The center
of the hole should line up with the centerline of
the rigid vent pipe. Cut a 10 3/4" x 10 3/4" square
hole through combustible exterior wall (8 1/2"
diameter hole if noncombustible). Frame as
necessary.

Slots
4. Three types of vent caps are available for
horizontal terminations. Two square terminals
are available; one for rigid pipe applications
and one for flex pipe applications. A round
vent termination with a slip fit connection is
also provided for rigid pipe applications to
be used when a wall thickness or off spacing must be accommodated. Each may be
purchased as a kit that includes a 45° elbow
and a firestop that accommodates a square or
round termination (see Parts List for Venting
Kits and Components, page 19).
Noncombustible Exterior Wall: Apply a bead
of non-hardening mastic around the outside
edge of the vent cap. Position the vent cap in
the center of the on the exterior wall with the
arrow on the vent cap pointing up. Attach the
vent cap with four wood screws provided (see
Figure 19). Note: Replace the wood screws
with appropriate fasteners for stucco, brick,
concrete, or other types of siding.
WARNING: Do not recess
vent termination in to any wall.
This will cause a fire hazard.

Combustible Exterior Wall: For vinyl siding,
stucco, or wood exteriors, a siding standoff
must be installed between the vent cap and
exterior wall. The siding standoff prevents
excessive heat from damaging siding materials.
Siding materials must be cut to accommodate
standoff. Bolt the vent cap to the standoff.
Apply non-hardening mastic around outside
edge of the standoff. Position the standoff/cap
assembly in the center of the square hole and
attach to exterior wall with wood screws provided (see Figure 20). The siding standoff must
sit flush against the exterior fascia material.

Vent system may be pre-sized. Check for final
fit and slide unit into framing with firestop in
place. This is helpful when using rigid pipe
and round vent termination. Vent may be
preconnected and slipped through firestop.
Make sure the 45° connection at unit is tight
and does not come loose before unit is nailed
to framing.
Square vent or long vent configuration: Vent
pipe must be manipulated at outer end to make
final connection. Manually secure pipe inside
open framing. If this is a retrofit installation in
an inaccessible space, you may have to secure
the outer end of vent pipe with wall straps and
tap screws at outer end.
When using tap screws with rigid pipe, be sure
that screws do not penetrate inner pipe. These
procedures may also be followed by flexible
pipe installations. To use flexible pipe, vent
must be drawn through end firestop, cut back
to 6"-8" to permit easy connection of flex
termination and connection must be slipped
back into and secured to installation. You
must use an adequate number of spring spacers at ends and closest bend to termination to
prevent kinks or collapsing on the fire. Do not
use screws with flex pipe. Vent system must
be code inspected and released before adding
dry wall or other surface treatments.

Note: Pay special attention to these installation instructions for required clearances (air
space) to combustibles when passing through
ceilings, walls, roofs, enclosures, attic rafters,
etc. Do not pack air spaces with insulation.
Also note maximum vertical rise of the venting system and any maximum horizontal
offset limitations. Offsets must fall within the
parameters shown in Figure 25.
2. Set the fireplace in desired location. Drop a
plumb line down from the ceiling to the position of the fireplace exit flue. Mark the center
point where the vent will penetrate the ceiling.
Drill a small locating hole at this point.
Drop a plumb line from the inside of the roof

Flat Ceiling Installation
1. Cut a 12 1/2" square hole in the ceiling using
the locating hole as a center point. The opening should be framed to 12 1/2"x12 1/2" inside
dimensions, as shown in Figure 18 on page
13 using framing lumber the same size as the
ceiling joists. If the area above the ceiling is
an insulated ceiling or an attic, nail firestop
from the top side. This prevents loose insulation from falling into the required clearance
space. If the area above the ceiling is a living
space, install firestop below the framed hole.
The firestop should be installed with no less
than three nails per side (see Figure 26).
2. Assemble the desired lengths of pipe and
elbows necessary to reach from the fireplace
flue up through the firestop. All connections
must be sealed with high temperature silicone
sealant as specified in the second warning
statement on page 11. Be sure all pipe and
elbow connections are fully twist-locked (see
Figure 17, page 13).
3. Cut a hole in the roof using the locating hole
as a center point. (Cover any exposed open
vent pipes before cutting hole in roof.) The
12 1/2" x 12 1/2" hole must be measured on
the horizontal; actual length may be larger
depending on the pitch of the roof. There
must be a 1" clearance from the vent pipe to
combustible materials. Frame the opening as
shown in Figure 18 on page 13.
4. Connect a section of pipe and extend up
through the hole. If an offset is needed to avoid
obstructions, you must support the vent pipe
every 3 feet. Use wall straps for this purpose
(see Figure 24, page 15). Whenever possible,
use 45° elbows instead of 90° elbows. The 45°
elbow offers less restriction to the flow of the
flue gases and intake air.
If area above is an attic, install firestop
above framed hole.
If area above is a living space, install
firestop below framed hole.

5. Place the flashing over the pipe section(s)
extending through the roof. Apply a bead of
silicone or roof sealer to the bottom flange of
flashing and secure the base of the flashing to
the roof and framing with roofing nails. Be
sure roofing material overlaps the top edge of
the flashing as shown in Figure 24, page 15.
There must be a 1" clearance from the vent
pipe to combustible materials.
6. Continue to add pipe sections until the height
of the vent cap meets the minimum building
code requirements described in Figure 14,
page 10. Note: You must increase vent height
for steep roof pitches. Nearby trees, adjoining
rooflines, steep pitched roofs, and other similar factors may cause poor draft or down-draft
condition (see Figure 24, page 15). Increasing
the vent height may solve this problem.
7. Apply a bead of sealer to the upper edge of
flashing collar. Slide storm collar over pipe
and down to top edge of flashing. Apply a
second bead of silicone or roof sealer around
remaining seam of storm collar. Twist-lock
vent cap onto last section of vent pipe and
seal with high temperature silicone sealant as
specified in the second warning statement on
page 11. Finish sealing flange around roofing
material with roofing sealer.
Note: If the vent pipe passes through any occupied
areas above the first floor, including storage spaces
and closets, you must enclose pipe. You may frame
and sheetrock the enclosure with standard construction material. Make sure and meet the minimum
allowable clearances to combustibles. Do not fill
any of the required air spaces with insulation.
Cathedral Ceiling Installation
1. Remove shingles or other roof covering as
necessary to cut the rectangular hole for the
support box. Mark the outline of the cathedral
ceiling support box on the roof sheathing using
the locating hole as a center point.
2. Cut the hole 1/8" larger than the support box
outline (see Figure 27).
3. Lower the support box through the hole in the
roof until the bottom of the box extends at least 2"
below the ceiling (see Figure 27). Align the support box vertically and horizontally using a level.
Temporarily tack the support box in place through
the inside walls and into the roof sheathing.
4. Using tin snips, cut the support box from the
top corners down to the roofline and fold the
resulting flaps over the roof sheathing (see
Figure 28). Apply a bead of non-hardening
mastic around the top edges of the support box
to make a seal between the box and the roof.
Nail in place with roofing nails. Remove any
combustible material that might be inside of
the support box.
5. Complete the cathedral ceiling installation
by following the same procedures outlined in
steps 2 through 7 for Flat Ceiling Installation,

High altitude installation
Your DESA direct-vent fireplace has been
tested and approved for elevations from 0-2,000
feet (USA) and elevations from 0-4,500 feet
(Canada)
Fireplaces for High Altitude (models ending in
-HA) are for installation above 4,000 feet only.
These fireplaces are equipped with parts specific
for higher altitudes. IMPORTANT: These fireplaces can NOT be converted to propane/LP gas.
When installing a non-high altitude fireplace at an
elevation above 2,000 feet (USA), you may need to
decrease the input rating by changing the existing
burner orifice to a smaller size. Reduce input 4%
for each 1,000 feet above sea level. Check with
your local gas company for proper orifice size
identification.
When installing this fireplace at an elevation
above 4,500 feet (Canada), check with local
authorities.
IMPORTANT: For horizontal installations
above 2,000 feet, it is recommened that a 12"
extension pipe be added before starter elbow
(see Figure 33).

DECORATIVE FACING
Any noncombustible material may be used for
facing (glass, tile, brick, etc.) as long as the proper
clearances are observed (see Clearances, page 6).
IMPORTANT: Louvered openings must not be obstructed, and upper and lower panels must remain
removable for servicing. Use only heat-resistant,
noncombustible mortar or adhesive when securing
facing material.
Note: Combustible material, such as wood, that
has been fireproofed is not considered noncombustible.
Pilot/Electrode
Assembly Adjustment
The pilot assembly is factory preset for the proper
flame height. Alteration to these settings may have
occurred during shipping and handling. If this is the
case, some minor adjustment may be necessary and
should be done by a qualified technician. To access
the pilot assembly, the glass door must be opened.
The proper settings for the thermopile height should
be at a distance of 3/8" to 1/2" from the pilot flame
as shown in Figure 52.
The electrode is installed at the factory for proper
positioning. However, alterations to the position
may have occurred due to shipping and handling.
These settings may need adjustment and must be
done by a qualified technician. The correct position
and height is as shown in Figure 53.
1/8"
(0.3cm)
3/8" - 1/2"

The air shutter, located at the base of the main
burner (see Figure 54), has been factory preset
to the proper air-to-gas ratio which results in an
even, clean burning flame across the burner (see
Figure 55). If readjustment is necessary, you can
restore the proper air-to-gas ratio by loosening the
air shutter screw and rotating the air shutter until
the proper flame setting is achieved (the shutter's
normal setting is fully open. Do not forget to
retighten the air shutter screw.

Instructions
When lit for the first time, the appliance may emit a
slight odor for about 16 - 24 hours. This is normal and
is due to the “curing” of the logs and the “burn-in” of
internal paints and lubricants used in the manufacturing process. Keep compartments, logs, burners, and
area surrounding the logs clean by vacuuming or
brushing at least twice a year. Temporary removal
of the log set may ease the cleaning of the burner and
pilot assembly. In cleaning, take care not to alter the
pilot or burner location. Be sure appliance is cool
before each maintenance session.
56131-F
CAUTION: The appliance and
logs can get very hot - Handle
only when cool.
WARNING: Turn off gas and
wall switch before servicing
appliance. Any safety screen or
guard removed for servicing the
appliance must be replaced prior
to operating the appliance.
WARNING: Make certain
wires and gas lines are not
touching the underside of the
firebox.
WARNING: Children and
adults should be alerted to the
hazards of high surface temperatures, and to stay away from
the appliance to avoid burns or
clothing ignition. Young children
should be carefully supervised
when they are in the same room
as the appliance.
WARNING: Have a qualified
agency periodically inspect the
vent system at the start of each
heating season, for any obstruction which may hinder its normal
operation. Never obstruct the
flow of combustion and ventilation air. Keep the front of the
appliance clear of all obstacles
and materials.
Caution: Label all wires
prior to disconnection when
servicing controls. Wiring errors
can cause improper and dangerous operation.

Warranty Information
KEEP THIS WARRANTY
Model
Serial No.
Date Purchased
Always specify model and serial numbers when communicating with the factory.
We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our
standard written warranty. We make no other warranty, expressed or implied.
LIMITED WARRANTY
DIRECT-VENT FIREPLACE
DESA warrants this product to be free from defects in materials and components for two (2) years from the date
of first purchase, provided that the product has been properly installed, operated and maintained in accordance
with all applicable instructions. To make a claim under this warranty the Bill of Sale or cancelled check must
be presented.
This warranty is extended only to the original retail purchaser. This warranty covers the cost of part(s) required to
restore this heater to proper operating condition and an allowance for labor when provided by a DESA Authorized
Service Center. Warranty part(s) MUST be obtained through authorized retailers of this product and/or DESA who
will provide original factory replacement parts. Failure to use original factory replacement parts voids this warranty.
The heater MUST be installed by a qualified installer in accordance with all local codes and instructions furnished
with the unit.
This warranty does not apply to parts that are not in original condition because of normal wear and tear or parts
that fail or become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by
improper installation. Travel, diagnostic cost, labor, transportation and any and all such other costs related to
repairing a defective heater will be the responsibility of the owner.
TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE
OF THE PRODUCT; THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED
WARRANTIES AND LIMITS THE DURATION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO TWO (2)
YEARS ON ALL COMPONENTS FROM THE DATE OF FIRST PURCHASE; AND DESA’S LIABILITY IS
HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA SHALL NOT BE LIABLE
FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.
Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of
incidental or consequential damages, so the above limitation on implied warranties or exclusion or limitation on
damages may not apply to you.
This warranty gives you specific legal rights and you may also have other rights that vary from state to state.
