CAST IRON STOVE AND BURNER SYSTEM

PRE-INSTALLATION
PREPARATION

WARNING: A qualified ser­vice person must install stove
and burner system. Follow all lo­cal codes.

CAUTION: This stove creates
warm air currents. These currents
move heat to wall surfaces next
to stove. Installing stove next to
vinyl or cloth wall coverings or
operating stove where impurities
(such as tobacco smoke, aro­matic candles, cleaning fluids,
oil or kerosene lamps, etc.) in the
air exist, may discolor walls.

LOCATION AND SPACE
REQUIREMENTS

Determine the safest and most efficient loca­tion for your Vanguard cast iron stove. Make
sure that rafters and wall studs are not in the
way of the venting system. Choose a location
where the heat output is not affected by
drafts, air conditioning ducts, windows, or
doors. Figure 2 shows some common loca­tions. Read all venting information in this
manual. Be aware of all restrictions and pre­cautions before deciding the exact location
for your stove.

When deciding the location of your stove,
follow these rules:

1. Do not connect this stove and burner
system to a chimney flue serving a
separate solid-fuel burning fireplace or
appliance.

2. Due to high temperatures, do not lo­cate this stove in high traffic areas or
near furniture or draperies.

3. Proper clearances must be maintained,
see Figure 3 and Figure 4 on page 5.

4. This stove is a freestanding unit de­signed to set directly on the floor. If
your stove is to be installed directly on
carpeting, vinyl tile, or any combustible
material other than wood, it must be
installed on a metal or wood panel ex­tending the full width and depth of the
stove. See Figure 5, page 5.

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 vent con­nections. Seal only the outer pipe
connections with high temperature
silicone (600°F/316° C). Before join­ing elbows and pipes, apply a bead
of high temperature silicone seal­ant (GE RTV 106/Loctite RTV 81585)
to the male 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 stove and burner
system 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 stove with
burner system 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

pipe 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 13 and 14.

For Vertical Termination: Measure the dis-

tance from the burner system 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 Ter-
mination Configurations on pages 16 and 17.

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 (see Figure 31, page 15).

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 stove with direct-vent burner
system has been tested for a maximum 17"
wall thickness when using a 60º elbow di­rectly into the back of the stove. The maxi­mum horizontal run is 20' with 8' vertical
rise (see Installation for Horizontal Termi-
nation, pages 11 and 12). The maximum
vertical run is 30' (see Installation for Ver-
tical Termination, pages 14 and 15).

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".

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
19 and 20). Snorkel kit SVKBK is also
available (see page 17). 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 20). 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 10.) Push
the pipe sections together and twist one sec­tion clockwise approximately one-quarter
turn until the sections are fully locked. See
Figure 21, page 12.
of vent must be supported every three feet.
Use wall straps for this purpose.

3. Attach vent pipe assembly to the burner
system. Set stove in front of it’s per­manent location to insure minimum
clearances. Mark the wall for a 10"
square hole (for noncombustible mate­rial such as masonry block or concrete,
a 7 1/2" diameter hole is acceptable). See
Figure 22. The center of the hole should
line up with the center-line of the hori­zontal rigid vent pipe. Cut a 10"x10"
(254mm x 254mm) square hole through
combustible exterior wall (7 1/2"
[190mm] diameter hole if noncombus­tible). Frame as necessary (see Figure

22).

4. Apply a bead of non-hardening mastic
around the outside edge of the vent cap.
Position the vent cap in the center of
the 7 1/2" or 10" hole on the exterior
wall with the word “up” on the vent cap
facing up. Insure proper clearance of
1" to combustibles is maintained. At­tach the vent cap with four wood screws
supplied (see Figure 23).

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, stucco, or wood ex­terior 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 24.

5. Slide the wall thimble over the vent pipe
before connecting the horizontal run to
the vent cap (see Figure 25).

6. Carefully move the stove 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 outer pipe connection. Fasten all
vent connections with screws provided.

7. Slide the wall thimble against the inte­rior wall surface and attach with screws
provided (see Figure 25).
