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 pipe to pipe 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: Do not seal termination cap to pipe. Cap must be removable for servicing vent 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 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 12.
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 14 and 15.
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, page 10.
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
Termination, pages 10 and 11). The maximum vertical run is 30' (see Installation for Vertical Termination, pages 13 and 14).
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 6 and 7) install the vent system by following the installation instructions.

12" Minimum
Snorkel
CAUTION: Horizontally terminated venting con-
figurations require one foot of vertical rise from the 45° elbow before any horizontal run can be made. Failure to meet venting requirements may cause performance problems and possible damage to the fireplace.
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.
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 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
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 9.) Push the pipe sections together and twist one section clockwise approximately one-quarter turn until the sections are fully locked. See Figure 16.

Note:
Horizontal runs of vent 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 10. All connections must be clamped tightly and sealed with high temperature silicone sealant as speci­fied in the second warning statement on page 9.
3. Attach vent pipe assembly to the fireplace. Set fireplace 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 hole is acceptable). See Figure 17. The center of the hole should line up with the center-line of the horizontal rigid vent pipe. Cut a 10"x10" (25.4cm x 25.4cm) square hole through combustible exterior wall (7 1/2" [19.1cm] diameter hole if noncombustible). Frame as necessary (see Figure 17).
4. Noncombustible Exterior Wall: Apply a bead of non-harden- ing mastic around the outside edge of the vent cap. Position the vent cap in the center of the 7 1/2" hole on the exterior wall with the arrow on the vent cap pointing up. Attach the vent cap with four wood screws prov id e d (see Figure 18). wood screws with appropriate fasteners for stucco, brick, con­crete, or other types of siding.

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 10" square hole and attach to exterior wall with wood screws provided (see Figure 19). The siding standoff must sit flush against the exterior fascia material.

Combustible Exterior Wall Only: Slide the interior wall
firestop 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". Fasten all vent pipe connections (except vent cap) with screws pro­vided. Refer to Fr aming on pages 6 and 7 for instructions on securing unit to framing or floor.
7. Combustible Exterior Wall Only: Slide the wall firestop against the interior wall surface and attach with screws pro­vided (see Figure 20).
