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.

Important:

Simpson Dura-Vent venting.

• 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.

• You must install a vinyl siding standoff if vinyl siding is covering the exterior wall.

• Install horizontal venting with a 1/4" rise for every 12" of run toward the termination.

• You may paint the vent terminal with 450ºF (232ºC) 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 prevent accidental blockage of venting system. When using snow blowers, do not direct snow towards vent termination area.

LOCATION OF VENT TERMINATION

When locating vent termination, it is important to observe the minimum clearances shown in Figure 8, 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.

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 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 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. 1 1/2" clearance is required where the termination penetrates a combustible wall. 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 T ermination

• 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 dis-

tance from the fireplace flue outlet to the ceiling. Add the ceiling thickness, the verti-

cal 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 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 and Finishing on page 4) install the vent system by following the installation instructions.

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 9 and 10). Snorkel kit SVK is also available (see page 15). Follow the same installation procedures as 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 10). 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 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 11, page 9.

Note:

Horizontal runs of vent must be supported every three feet. Use wall straps for this purpose.

Flexible vent pipe must be installed with separation spacer springs every 12". See Figure 11, page 9. All connections must be clamped tightly and sealed with high temperature silicone sealant as specified in the second warning on page 7.

3. Attach vent pipe assembly to the fireplace. Set fireplace in front of it’s permanent location to insure minimum clearances. See page 10, Figure 16 for minimum clearances for vertical on rigid vent pipe, and page 10, Figure 17 on flexible vent pipe. 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 12. 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 12).

INSTALLATION FOR 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 21) 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 8 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.

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 12 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 22).

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 on page

7. Be sure all pipe and elbow connections are fully twist-locked (see Figure 11, 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 Figure12 on page 9.

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

If area above is not a room, install firestop below 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 21). Whenever 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

21. 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 8 on page 6. 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 outer pipe connection with high temperature silicone sealant as specified in the second warning 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.

INSTALLING GAS PIPING TO FIREPLACE LOCATION

WARNING: A qualified service person must connect fireplace to gas supply. Follow all local codes.

CAUTION: For propane/LP units, never connect heater directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and propane/LP supply.

Installation Items Needed

Before installing fireplace, make sure you have the items listed below:

• external regulator (supplied by installer)

• piping (check local codes)

• sealant (resistant to propane/LP gas)

• equipment shutoff valve *

• test gauge connection *

• sediment trap

• tee joint

• pipe wrench

• approved flexible gas line with gas connector (if allowed by local codes) (not provided)

* An CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the CSA design-certified equipment shutoff valve from your dealer.

For propane/LP connection only, the installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 34. Pointing the vent down protects it from freezing rain or sleet.

CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" diameter or greater to allow proper gas volume to fireplace. If pipe is too small, undue loss of pressure will occur.

Installation must include an equipment shutoff valve, union, and plugged 1/8" NPT

IMPORTANT:

valve in an accessible location. The equipment shutoff valve is for turning on and shutting off the gas to the appliance.

Check your building codes for any special requirements for locating equipment shutoff valve to fireplaces.

Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged fireplace valves.

Install equipment shutoff

tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from fireplace (see Figure 35).

CAUTION: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

Propane/LP Supply Tank

We recommend that you install a sediment trap/drip leg in supply line as shown in

External Regulator

Figure 35. Locate sediment trap/drip leg where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate sediment trap/drip leg where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into

OPERATING

OPTIONAL BLOWER

ACCESSORY

Locate the blower controls by opening the lower louver panel on the fireplace. Blower controls are located on the left side of the switch bracket to the left just inside the louver panel.

Both the GA3700 manual blower and the DA3610TA thermostatically-controlled blower have an ON setting and an OFF setting. The blower will only run when the switch is in the ON position. In the OFF position, the blower will not operate.

Note for DA3610TA Only:

using DA3610TA blower, your fireplace and blower will not turn on and off at the same time. The fireplace may run for several minutes before the blower turns on. After the heater modulates to the pilot position, the blower will continue to run. The blower will shut off after the firebox temperature decreases.

The blower helps distribute heated air from the fireplace. Periodically check the louvers of the firebox and remove any dust, dirt, or other obstructions that will hinder the flow of air.

If you are

INSPECTING BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT ASSEMBLY

The pilot assembly is factory preset for the proper flame height. Alterations may have occurred during shipping and handling. Call a qualified service person to readjust the pilot if necessary.

Figure 54 - Correct Pilot Flame Pattern

BURNER FLAME PATTERN

Burner flames will be steady; not lifting or floating. Flame patterns will be different from unit to unit and will vary depending on installation type and weather conditions.

If the vent configuration is installed incorrectly, the flames will lift or “ghost”. This can be dangerous. Inspect the flames after installation to ensure proper installation and performance.

Figure 55 shows a typical flame pattern for these modles. If burner flame pattern differs from that described:

• turn fireplace off (see To Turn Off Gas to

Appliance, page 24)

• see Troubleshooting, pages 27 through 29

CLEANING AND MAINTENANCE

WARNING: Turn off fireplace

and let cool before cleaning.

CAUTION: You must keep control areas, burners, and circulating air passageways of fireplace clean. Inspect these areas of fireplace before each use. Have fireplace inspected yearly by a qualified service person. Fireplace may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.

GLASS DOOR

WARNING: Handle glass door panel with care. Do not strike, slam, or otherwise abuse glass. Do not operate fireplace with the glass door removed, cracked, or broken.

WARNING: Do not use abrasive cleaners as this may damage glass. Use a nonabrasive household glass cleaner to clean glass. Do not clean glass when hot.

Glass must be cleaned periodically. During start-up it is normal for condensation to form on the inside of the glass causing lint, dust, and other airborne particles to cling to the glass surface. During initial start-up a slight film may form on the glass due to paint curing. The glass should be cleaned several times with a non-ammonia, nonabrasive household cleaner and warm water after the first two weeks of operation. Thereafter, clean the glass two or three times during each heating season, depending on the usage and circumstances present. Refer to Removing/Replacing Glass Door on page 21 of this manual when removing glass door for cleaning.

WARNING: Only parts supplied by the manufacturer should be used when replacing broken or damaged glass door panel (see

Replacement Parts

glass door panel is a complete unit. No substitute materials may be used.

CAUTION: Wear gloves and safety glasses while handling or removing broken glass. Do not remove if glass is hot. Keep children and pets away from glass.

If glass has been broken, carefully remove glass door (see Removing/Replacing Glass Door, page 21). Vacuum all glass pieces with a shop vac.

CAUTION: Do not vacuum if pieces are hot.

Use only the glass door replacement intended for this fireplace (see Replacement Parts, page 30 for detail on ordering). No substitutions may be made. See Removing/ Replacing Glass Door, page 21 for instructions for replacing glass door.

WARNING: Do not operate fireplace with the glass door removed, cracked, or broken.

, page 30). This

PILOT AND BURNERS

• Remove ember material before cleaning burners and replace when cleaning is complete.

• Burner and controls should be cleaned with compressed air to remove dust, dirt, or lint.

• Use a vacuum cleaner or small, soft bristled brush to remove excess dust, dirt, or lint.

LOGS

• If you remove logs for cleaning, refer to

Installing Logs, Lava Rock, and Glowing Embers, page 23, to properly replace logs.

• Use a vacuum cleaner to remove any carbon build up on logs.

• Replace log(s) if broken. See Replace- ment Parts on page 30.

• Replace ember material periodically as needed. See Replacement P arts on page 30.

VENTING SYSTEM

Conduct annual inspection of the venting system following these guidelines:

1. Check areas of venting system that are

exposed to the weather for corrosion (rust spots or streaks and, in extreme cases, holes). Have these items replaced immediately by a qualified service person.

2. Remove the vent cap and shine a flash-

light into the vent. Remove any foreign material.

3. Check for evidence of excessive con-

densation. Continuous condensation can cause corrosion of caps, pipes, and fittings and can be caused by having excessive lateral runs, too many elbows, or exterior portions of the system being exposed to cold weather.

4. Inspect joints to verify that no pipe sec-

tion or fitting has been disturbed and loosened. Check mechanical supports such as wall straps for rigidity.
