GENERAL VENTING

These models are approved for use with 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.

• If installing on vinyl siding a vinyl siding standoff must be used (see Figure 19, page 9).

• 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.

• 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.

• Do not locate termination cap where excessive snow or ice build up may occur. Be sure to clear vent termination area after snow falls to prev ent accidental blockage of venting system. When using sno w blowers, do not direct snow to wards vent termination area.

LOCATION OF VENT TERMINATION

When locating vent termination, it is important to observe the minimum clearances shown in Figure 13, page 6. You will avoid extra framing by positioning your fireplace against an already existing framing member. The sides of the fireplace may be positioned directly against combustible walls.

*Check with local codes or with the current

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 outer pipe connections with high temperature silicone (600°F/316° C) every time a vent connection is made. Before joining elbows and pipes, apply a small bead of high temperature silicone sealant (GE RTV 106/Loctite RTV 81585) to the outer section of 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 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

• 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.

Note:

The location

1' Minimum

90°

12" Minimum

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.

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 1/2" diameter hole is acceptable). See Figure 17. 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 17).

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 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 w all. 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).

INSTALLATION FOR VERTICAL TERMINATION

NOTICE: Use rigid pipe only. Flex venting is not to be used with a vertical termination.

1. Determine the route your vertical venting will take. If ceiling joists, roof rafters, or other framing will obstruct the venting system, consider an offset (see Figure 24) to avoid cutting loadbearing members. cial attention to these installation instructions for required clearances (air space) to combustibles when passing through ceilings, walls, roofs, enclosures, attic rafters, etc. Do not pack air spaces with insulation. Also note maximum vertical rise of the venting system and any maximum horizontal offset limitations. Offsets must fall within the parameters shown in Figure 13 on page 6.

2. Set the fireplace in desired location. Drop a plumb line down from the ceiling to the position of the fireplace exit flue. Mark the center point where the vent will penetrate the ceiling. Drill a small locating hole at this point.

Drop a plumb line from the inside of the roof to the locating hole in the ceiling. Mark the center point where the vent will penetrate the roof. Drill a small locating hole at this point.

Note:

Flat Ceiling Installation

1. Cut a 10" square hole in the ceiling using the locating hole as a center point. The opening should be framed to 10"x10" (254mm x 254mm) inside dimensions, as shown in Figure 17 on page 9 using framing lumber the same size as the ceiling joists. If the area above the ceiling is an insulated ceiling or a room, nail firestop from the top side. This prevents loose insulation from falling into the required clearance space. Otherwise, install firestop below the framed hole. The firestop should be installed with no less than three nails per side (see Figure 25).

2. Assemble the desired lengths of pipe and elbows necessary to reach from the fireplace flue up through the firestop. All connections must be sealed with high temperature silicone sealant as specified in the second warning statement on page 7. Be sure all pipe and elbow connections are fully twistlocked (see Figure 16, page 9).

3. Cut a hole in the roof using the locating hole as a center point. (Cover any exposed open vent pipes before cutting hole in roof.) The 10"x10" hole must be measured on the horizontal; actual length may be larger depending on the pitch of the roof. There must be a 1" clearance from the vent pipe to combustible materials. Frame the opening as shown in Figure 17 on page 9.

If area above is a room, install firestop above framed hole.

4. Connect a section of pipe and extend up through the hole.

Note:

If an offset is needed to avoid obstructions, you must support the vent pipe every 3 feet. Use wall straps for this purpose (see Figure 24). Whenev er possible, use 45° elbows instead of 90° elbows. The 45° elbow offers less restriction to the flow of the flue gases and intake air.

5. Place the flashing over the pipe section(s) extending through the roof. Secure the base of the flashing to the roof and framing with roofing nails. Be sure roofing material overlaps the top edge of the flashing as shown in Figure

24. There must be a 1" clearance from the vent pipe to combustible materials.

6. Continue to add pipe sections until the height of the vent cap meets the minimum building code requirements described in Figure 13 on page 6. You must increase vent height for steep roof pitches. Nearby trees, adjoining rooflines, steep pitched roofs, and other similar factors may cause poor draft or down-drafting in high winds. Increasing the vent height may solve this problem.

7. Twist-lock the vent cap onto the last section of vent pipe and seal with high temperature silicone sealant as specified in the second warning statement on page 7.

Note:

If the vent pipe passes through any occupied areas above the first floor, including storage spaces and closets, you must enclose pipe. You may frame and sheetrock the enclosure with standard construction material. Make sure and meet the minimum allowable clearances to combustibles. Do not fill any of the required air spaces with insulation.

3. Lower the support box through the hole in the roof until the bottom of the box extends at least 2" below the ceiling (see Figure 26). Align the support box vertically and horizontally using a level. Temporarily tack the support box in place through the inside walls and into the roof sheathing.

4. Using tin snips, cut the support box from the top corners down to the roofline and fold the resulting flaps over the roof sheathing (see Figure 27). Apply a bead of non-hardening mastic around the top edges of the support box to make a seal between the box and the roof. Nail in place with roofing nails. Remove any combustible material that might be inside of the support box.

5. Complete the cathedral ceiling installation by following the same procedures outlined in steps 2 through 7 for Flat Ceiling Installation, page 12

GAS LINE HOOK-UP

WARNING: Before you proceed, make sure your gas supply is OFF.

WARNING: Gas line hookup should be done by your gas supplier or a qualified service person.

A equipment shutoff valve has been included in the appliance’s gas supply system. You may consider installing an extra gas shutoff valve outside the appliance’s enclosure (check with local codes) where it can be accessed more conveniently with a key through a wall as shown in Figure 39.

Shutoff Valve

Route a 1/2” NPT black iron gas line towards the appliance coming in from the left. It is recommended to route the pipe between the stand of the firebox and the surround of the fireplace (see Figure 40).

IMPORTANT:

The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig. (3.5 kPa). The appliance must be isolated from the gas supply piping system by closing its individual equipment shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig. (3.5 kPa).

CAUTION: Do not kink flex-

ible gas line.

CAUTION: Compounds used on threaded joints of gas piping shall be resistant to the action of Liquefied Petroleum (LP or propane), and should be applied lightly to ensure excess sealant does not enter the gas line.

1. Install a sediment trap between the incoming gas line and the gas control valve (see Figure 40). The sediment trap should extend down the center of the pipe. Refer to your local codes.

2. Prepare incoming gas line and check with local codes regarding the use of teflon tape. Complete your gas line installation by connecting incoming gas line with flexible gas line. Secure tightly with a wrench, but Do NOT

Overtighten.

OPERATING GUIDELINES AND MAINTENANCE INSTRUCTIONS

When lit for the first time, the appliance may emit a slight odor for about 16 - 24 hours. This is normal and is due to the “curing” of the logs and the “burn-in” of internal paints and lubricants used in the manufacturing process. Keep compartments, logs, burners, and area surrounding the logs clean by vacuuming or brushing at least twice a year. Temporary removal of the log set may ease the cleaning of the burner and electrode assembly. In cleaning, take care not to alter the electrode or burner location. Be sure appliance is cool before each maintenance session.

CAUTION: The appliance and logs can get very hot - Handle only when cool.

WARNING: Turn off gas and wall switch before servicing appliance. Any safety screen or guard removed for servicing the appliance must be replaced prior to operating the appliance.

Any household glass cleaner may be used to clean the glass panel. Do not use abrasive cleaners as this may damage the glass. Clean

glass only when cool.

CAUTION: If the glass breaks, be cautious of fragments on the floor. Keep children away from the area. Do not operate the unit. Use proper safety gloves to remove the broken glass door. Discard safely. A glass door kit can be ordered through your local distributor. Do not substitute other material for the glass.

WARNING: Children and adults should be alerted to the hazards of high surface temperatures, and to stay away from the appliance to avoid burns or clothing ignition. Young children should be carefully supervised when they are in the same room as the appliance.

WARNING: Have a qualified agency periodically inspect the vent system at the start of each heating season, for any obstruction which may hinder its normal operation. Never obstruct the flow of combustion and ventilation air. Keep the front of the appliance clear of all obstacles and materials.

WARNING: Do not abuse, strike, or slam the glass doors.

WARNING: Do not operate appliance with panel(s) and glass removed, cracked, or broken. Replacement of the panel(s) should be done by a licensed, qualified service person.

WARNING: Make certain wires and gas lines are not touching the underside of the firebox.

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.

For further operating guidelines, contact your authorized dealer.
