Simpson Dura-Vent 6 5/8" direct-vent pipe
components and terminations as well as both
flex and rigid Vanguard vent components.

Your fireplace is approved to be vented either
through the side wall, or vertically using the
following guidelines:

• Only use Vanguard or Simpson Dura­V ent GS venting components or kits spe­cifically approved for this fireplace.

• Minimum clearance between vent pipes
and combustible materials is 1" (25 mm),
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.

• Install horizontal venting with a 1/4"
rise for every 12" of run tow ard the ter­mination.

• You may paint the vent terminal with
450°F (232°C) heat-resistant paint to co­ordinate with the exterior finish.

OWNER’S MANUAL

VENTING
INSTALLATION

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. Operation of im­properly installed and maintained
venting system could result in
serious injury, property damage
or loss of life.

WARNING: Seal all of the con­nections with high temperature
silicone (600°F/316° C) every time
a vent connection is made. Be­fore joining elbows and pipes,
apply a bead of high temperature
silicone sealant (GE RTV 106/
Loctite RTV 81585) to the end of
the elbow or pipe. High tempera­ture silicone must also be used
to re-seal any connections after
maintenance to venting system.

NOTICE: Failure to follow these
instructions will void the warranty.

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
International

• 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 Ter mination

• 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 Termina-
tion Configurations on pages 10 and 11.

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 roofline.

You may use one or two 90° elbows in this
vent configuration. See Vertical Termination
Configurations on pages 13 and 14.

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,
below.

Your Vanguard direct-vent fireplace has
been tested for a minimum 3' rise with a
maximum 10" wall thickness. The maxi­mum horizontal run is 20' with 8' vertical
rise (see Installation for Horizontal Termi-
nation, page 8). The maximum vertical run
is 30' (see Installation for Vertical Termina-
tion, page 12).

It is very important that the venting system
maintain its balance between the combus­tion air intake and the flue gas exhaust.
Certain limitations apply to vent configura­tions and must be strictly followed.

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. A chase is not required for
such venting.

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
pages 4 and 5) install the vent system by
following the installation instructions.

INSTALLATION FOR
HORIZONTAL TERMINATION

1. Determine the route your horizontal
venting will take.
of the horizontal vent termination on
the exterior wall must meet all local and
national building codes and must not
be easily blocked or obstructed.

WARNING: Do not recess vent

terminal into a wall or siding.

Snorkel terminations are available for
terminations requiring a vertical rise on
the exterior of the building (see Figures
14 and 15). Snorkel kit SVK is also
available (see page 15). Follow the same
installation procedures used for standard
horizontal terminations. If installing the
snorkel termination below grade (base­ment applications), you must provide
proper drainage to prevent water from
entering the snorkel termination (see
Figure 15). 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 7.) Push the pipe sections
together and twist one section clockwise
approximately one-quarter turn until the
sections are fully locked. See Figure 16,
page 9.
must be supported every three feet. Use
wall straps for this purpose.

Flexible vent pipe must be installed with
spacer springs every 12". See Figure 16,
page 9. All connections must be clamped
tightly and sealed with high temperature
silicone sealant as specified in the sec­ond warning statement on page 7.

1" to combustibles is maintained. At­tach the vent cap with four wood screws
supplied (see Figure 18).

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.

For vinyl siding use vinyl siding stand­offs between vent cap and exterior wall.
The vinyl siding standoff prevents ex­cessive heat from melting the vinyl sid­ing material. Bolt the vent cap to the
standoff. Apply non-hardening mastic
around outside edge of the standoff in­stead of the vent cap assembly. Use
wood screws provided to attach the
standoff. See Figure 19.

5. Slide the wall thimble over the vent pipe
before connecting the horizontal run to
the vent cap (see Figure 20).

6. Carefully move the fireplace with vent
assembly attached toward the wall and
insert the vent pipe into the horizontal
termination. The pipe overlap should be
a minimum of 1 1/4". Apply silicone to
the connection. Fasten all vent connec­tions with screws provided. Refer to
Framing on pages 4 and 5 for instruc­tions on securing unit to framing or floor.

7. Slide the wall thimble against the inte­rior wall surface and attach with screws
provided (see Figure 20).

INSTALLATION FOR
VERTICAL TERMINATION

NOTICE: Use rigid pipe only. Flex
venting is not to be used with a
vertical termination.

1. Determine the route your vertical vent­ing will take. If ceiling joists, roof
rafters, or other framing will obstruct
the venting system, consider an offset
(see Figure 24) to avoid cutting
loadbearing members.
cial 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 13 on
page 6.

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 to the locating hole in the ceil­ing. Mark the center point where the
vent will penetrate the roof. Drill a
small locating hole at this point.

Note:

Pay spe-

Roof
Flashing

Flat Ceiling Installation

1. Cut a 10" square hole in the ceiling us­ing the locating hole as a center point.
The opening should be framed to
10"x10" (254mm x 254mm) inside di­mensions, as shown in Figure 17 on
page 9 using framing lumber the same
size as the ceiling joists. If the area
above the ceiling is an insulated ceil­ing or a room, nail firestop from the
top side. This prevents loose insulation
from falling into the required clearance
space. Otherwise, install firestop below
the framed hole. The firestop should be
installed with no less than three nails
per side (see Figure 25).

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 7. Be sure all pipe and
elbow connections are fully twist­locked (see Figure 16, page 9).

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 10"x10" 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 17 on page 9.

If area above is a room, install firestop
above framed hole.

4. Connect a section of pipe and extend
up through the hole.

Note:

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). Whenev er
possible, use 45° elbows instead of 90°
elbows. The 45° elbow offers less re­striction to the flow of the flue gases
and intake air.

5. Place the flashing over the pipe
section(s) extending through the roof.
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. 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 13 on page 6.
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-draft­ing in high winds. Increasing the vent
height may solve this problem.

7. Twist-lock the vent cap onto the last
section of vent pipe and seal with high
temperature silicone sealant as speci­fied in the second warning statement
on page 7.

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.

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 26). 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 27). 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

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 4).

IMPORTANT:

vered 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 ASSEMBLY
ADJUSTMENT

The pilot assembly is factory preset for the

Front

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 47.

BURNER FLAME
ADJUSTMENT

Front

The air shutter, located at the underside of the
main burner (see Figure 48), has been factory
preset to the proper air-to-gas ratio which
results in an even, clean burning flame across
the burner (see Figure 49). If readjustment is
necessary, you can restore the proper air-to­gas 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 “full opened”. Do not forget to
retighten the air shutter screws.

CAUTION: Before proceed­ing, make sure the entire unit is
cool.

1. Remove the top and bottom louvers and
screen. Open the glass door (left or right
side).

2. Carefully remove the log set.

3. Remove the screw that attaches the
burner to the bracket.

4. Slide the burner towards the front of
the unit, lift, and remove from the fire­box.

5. To reinstall the burner , slide the b urner
towards the rear of the unit and secure
burner to bracket with screw.

CAUTION: Make certain the
orifice is inside the venturi tube's
air shutter, see Figure 48.

6. Replace the log set, close door with
latches, and attach screen and louvers.

OPERATING
GUIDELINES AND
MAINTENANCE
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.

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.

Any household glass cleaner may be used to
clean the glass panel. Do not use abrasive
cleaners as this may damage the glass. Clean

glass only when cool.

WARNING: Do not operate
appliance with panel(s) and glass
removed, cracked, or broken. Re­placement of the panel(s) should
be done by a licensed, qualified
service person.

WARNING: Make certain wires
and gas lines are not touching
the underside of the firebox.

CAUTION: If the glass breaks,
be cautious of fragments on the
floor. Keep children away from
the area. Do not operate the unit.
Use proper safety gloves to re­move the broken glass door. Dis­card safely. A glass door kit can
be ordered through your local
distributor. Do not substitute
other material for the glass.

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.

WARNING: Do not abuse,
strike, or slam the glass doors.

CAUTION: Label all wires
prior to disconnection when ser­vicing controls. Wiring errors
can cause improper and danger­ous operation.

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 dealers of this product and/or DESA International 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 FOUR (4) YEARS ON ALL COMPONENTS FROM THE DATE OF FIRST PURCHASE; AND DESA
INTERNATIONAL’S LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA INTERNA­TIONAL 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.
