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.

pointing up. Insure proper clearance of
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).
