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 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 reseal 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 installer or 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 vent 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 vent pipe.

INSTALLATION PLANNING

There are two basic types of direct-vent installation:

• Horizontal Termination

• V ertical 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.

A MDVGFK ground floor horizontal vent kit is specifically designed for common horizontal installations in manufactured (mobile) homes. Additional horizontal installations are described on page 9. All vent kits and components are listed on page 13.

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 a horizontal vent configuration. See Horizon- tal Termination Configurations on page 9.

For Vertical Termination: Measure the dis-

tance 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 a

vertical vent configuration. See Vertical Ter- mination Configurations on pages 11 and 12.

Note:

You may use two 45° elbows in place of a 90° elbow. You must follow rise to run ratios when using 45° elbows.

The MDV9K 9' vertical vent kit is specifically designed for common vertical installations in manufactured (mobile) homes. Additional vertical installations are described on pages 11 and 12. All vent kits and components are listed on page 13.

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, pages 7 through 9). The maximum vertical run is 40' (see Installation for Ver- tical Termination, page 10 through 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 boxlike 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 page 4) install the vent system by following the installation instructions.

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 11 and 12). Snorkel kit SVK is also available (see page 13). 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 12). 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 6.) Push the pipe sections together and twist one section clockwise approximately one-quarter turn until the sections are fully locked. See Figure 13, page 8. 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 13, page 8. All connections must be clamped tightly and sealed with high temperature silicone sealant as specified in the second warning statement on page 6.

3. Attach vent pipe assembly to the fireplace. Set fireplace in front of it’s per manent 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 14. The center of the hole should line up with the centerline 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 14).

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 arrow on the vent cap pointing up. Insure proper clearance of 1" to combustibles is maintained. Attach the vent cap with four wood screws supplied (see Figure 15).

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 or stucco 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 16.

5. Slide the wall thimble over the vent pipe before connecting the horizontal run to the vent cap (see Figure 17).

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 outer pipe connection. Fasten all vent connections with screws provided. Refer to Fr aming on page 4 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 17).
