PRODUCT FEATURES

These are a few facts that can help you under-
stand and enjoy your direct vent replace:
• The venting system may be routed to the outside of your home in several ways. It
may vent through the roof (vertical) or it
may vent to an outside/exterior wall (hori-
zontal). The vent pipe installation is very
important to allow for proper operation. You must follow the venting instructions
very carefully for either vertical or horizontal
applications.

PREINSTALLATION

LOCATION AND SPACE REQUIREMENTS
Determine the safest and most efcient loca­tion for your direct vent replace. 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. Be aware of all restrictions and precautions before
deciding the exact location for your replace
and termination cap.
When deciding the location of your replace,
follow these rules:
• Do not connect this replace venting to a chimney ue serving a separate solid-fuel burning replace or appliance.
• Due to high temperatures, do not locate this
replace in high trafc areas, windy or drafty
areas or near furniture or draperies.
• Proper clearances must be maintained.
• If your replace 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 replace (see Figure 3).
• Your replace is designed to be used in zero clearance installations. Wall or framing
material can be placed directly against any exterior surface on the back, sides or top of your replace, except where standoff spac­ers are integrally attached. If standoff spac-
ers are attached to your replace, these
spacers can be placed directly against wall or framing material. See framing details on page 6.
• When locating termination cap, it is impor­tant to observe the minimum clearances shown in Figure 7, page 7.
• If recessing into a wall, you can avoid extra
framing by positioning your replace against
an already existing framing member.
• Do not recess termination cap into a wall or siding.
• You may paint the termination cap with
450º F (232º C) heat-resistant paint to coordinate with the exterior nish.
• 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 and the front of outside air vent.
• Do not locate termination cap and outside air vent 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.

VENTING INSTALLATION

NOTICE: Read these instruc-
tions completely before at­tempting installation.
These models are tested and approved for
use with DESA (direct vent) pipe components
and terminations. The venting system must terminate on the
outside of the structure and can not be at-
tached to a chimney or ue system serving a
separate solid fuel or gas burning appliance. A direct vent appliance must have its own venting system. DO NOT common vent this appliance.
These models are approved to be vented
either horizontally through an outside wall or
vertically through a roof or chase enclosure using the following guidelines:
• When venting system terminates horizon­tally on an outside wall, you may install a standoff if the termination cap is to be
installed directly on a combustible nish
such as vinyl, wood, stucco, etc.
• Never run the vent downward as this may cause excessive temperatures which could
cause a re.
• Vent pipe air space clearances to com­bustibles are 1" on all sides except on the horizontal sections, which requires 2" clear­ance from the top of the pipe. Where the termination cap penetrates a combustible
wall, 1" air space clearance is required.
• Have replace and selected vent compo-
nents on hand to help determine the exact measurements when elbowing or offsetting.
Always use wall restops when penetrating walls and restops when penetrating ceil-
ings or attic spaces.
• For installation of replace at elevations of
4000 feet or greater, pay special attention
to venting requirement recommendations.
WARNING: Read all instruc-
tions completely and thoroughly before attempting installation.
Failure to do so could result in
serious injury, property damage or loss of life.
NOTICE: Failure to follow these in-
structions will void the warranty.
NOTICE: Do not seal termination
cap to vent pipe. Cap must be removable for vent inspection and maintenance.
INSTALLATION PRECAUTIONS
• We ar glo ves an d safe t y gla s ses fo r 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:
• In s tal lati on of any da mage d ven tin g component
• Unauthorized modication of the venting sys­tem (Do not cut or alter vent components)
• Installation of any component part not manufactured or approved by DESA
• Installation other than as instructed by these instructions
WARNING: This gas replace 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 direct vent gas appliance must use a separate vent system. Do not use com­mon vent systems.
WARNING: Vent pipe air space clearances to combus­tibles are 1" on all sides except on the horizontal sections, which require 2" clearances from the top of the pipe. Where the termination cap penetrates a combustible wall, 1" air space clearance is required.

INSTALLATION PLANNING
There are two basic types of direct vent installation:
• Horizontal Termination
• Vertical Termination
Outside air ex installation is required for both horizontal and vertical installation (see page 13).
Horizontal Termination Installation
IMPORTANT: Horizontal square terminations require only inner portion of wall restop. Hori­zontal installations using round termination require exterior portion of wall restop.
1. Set the replace in its desired location and determine the route your horizontal vent­ing will take. Do not secure the replace
until all venting has been installed. Some
installations require sliding the replace in and out of position to make nal vent-
ing connections. Figures 14 and 15 on
page 11 show different congurations for venting with horizontal termination that
will help you decide which application best suits your installation. Check to see if wall studs or roof rafters are in the path of your desired venting route. If they are,
you may want to adjust the location of the replace.
2. Direct vent pipe sections and compo­nents are designed with special twist-lock connections.
Twist- Lo ck Procedure: The female
ends of the pipes have locking lugs (in-
dentations). These lugs will slide straight
into matching slots on the male ends
of adjacent pipes. Push pipe sections
together and twist one section clockwise
approximately one-quarter turn until the sections are fully locked (see Figure 8).
Note: Horizontal runs of vent must be sup- ported every three feet. Use wall straps for this purpose.
3. Assemble the desired combination of pipe
and elbows to the replace ue collar. If
there are long portions of venting run, pre­assembled pipe sections may be installed as subassemblies for convenience.
4. Carefully determine the location where the vent pipe assembly will penetrate the outside wall. The center of the hole should line up with the center-line of the
horizontal vent pipe. Mark the wall for
an 11 1/2" x 11 1/2" square hole. Cut and
frame the square hole in the exterior
wall where the vent will be terminated. If the wall being penetrated is constructed of noncombustib le material, such as masonry block or concrete, a 8 1/2" hole
with zero clearance is acceptable (see Figure 9).

VENTING INSTALLATION
Continued
WARNING: Do not recess
vent termination into any wall. This will cause a re hazard.
5. Noncombustible Exterior Wall: Position
the horizontal vent cap in the center of the
8 1/2" round hole and attach to the exterior wall with four wood screws provided. Before attaching the vent cap to exterior wall, run a bead of non-hardening mastic
(pliable sealant) around the outside edges
to make a seal between it and the outside wall. Note: The four wood screws provided should be replaced with appropriate fas­teners for stucco, brick, concrete or other
types of sidings (see Figure 10).
Combustible Exterior Wall: For vinyl
siding, stucco or wood exteriors, a siding standoff may be installed between the vent cap and exterior wall. The siding standoff prevents excessive heat from damaging the siding materials. Siding material must be cut to accommodate standoff. Bolt the vent cap to the stand­off. Apply non-hardening mastic around outside edge of standoff. Position the standoff/cap assembly in the center of the 11 1/2" square hole and attach to exterior wall with wood screws provided (see Fig-
ure 11). The siding standoff must sit ush
against the exterior fascia material.
6. Combustible Exterior Wall Only: Slide
the wall restop over the vent pipe before connecting horizontal run to vent cap (see Figure 12).
7. Carefully move replace, with vent as-
sembly attached, toward wall and insert
vent pipe into horizontal termination. The
pipe overlap should be a minimum of 1 1/4"
(see Figure 13, page 11).
8. Combustible Exterior Wall Only: Slide
wall restop against interior wall surface
and attach with screws provided. See Fig-
ure 13, page 11, for horizontal termination
details.
9. Place replace into position and shim with
noncombustible material if needed. Nail or
screw side anges to framing to secure unit in place. IMPORTANT: Make sure re- place is level before securing. If replace
is not level it will not work properly.
