LOCATION OF VENTTERMINATIONWhen locating vent termination, it is impor-tant to observe the minimum clearancesshown in Figure 8, page 6. You will avoidextra framing by positioning your fireplaceagainst an already existing framing mem-ber. The sides of the fireplace may be posi-tioned directly against combustible walls.

*Check with local codes or with the currentCAN/CGA B149[.1 or .2] Installation Codesfor Canada or the USA Installations followthe current National Fuel Gas Code, ANSZ223.1, also known as NFPA 54.

These models are approved for use withSimpson Dura-Vent 6 5/8" direct-vent pipecomponents and terminations, as well as bothflex and rigid Vanguard vent components.

Your fireplace is approved to be vented eitherthrough the side wall, or vertically using thefollowing guidelines:• Only use Vanguard or Simpson Dura-

Vent GS venting components or kits spe-cifically approved for this fireplace.Important: Do not mix Vanguard andSimpson Dura-Vent venting.

• Minimum clearance between vent pipesand combustible materials is 1" (25 mm),except where stated otherwise.

• Combustible material may be flush withthe top front of fireplace with a maxi-mum thickness of 3/4".

• Do not recess venting terminals into awall or siding.

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

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

• You may paint the vent terminal with450ºF (232ºC) heat-resistant paint to co-ordinate with the exterior finish.

• There must not be any obstruction suchas bushes, garden sheds, fences, decks,or utility buildings within 24" from thefront of the termination cap.

• Do not locate termination cap where exces-sive snow or ice build up may occur. Be sureto clear vent termination area after snow fallsto prevent accidental blockage of ventingsystem. When using snow blowers, do notdirect snow towards vent termination area.

OWNER’S MANUAL


WARNING: Read all instruc-tions completely and thoroughlybefore attempting installation.Failure to do so could result inserious injury, property damageor loss of life. Operation of im-properly installed and maintainedventing system could result inserious injury, property damageor loss of life.

WARNING: Seal all vent con-nections. Seal only the outer pipeconnections with high temperaturesilicone (600 °F/316° C). Before join-ing elbows and pipes, apply a beadof high temperature silicone seal-ant (GE RTV 106/Loctite RTV 81585)to the male end of the elbow orpipe. High temperature siliconemust also be used to re-seal anyconnections after maintenance toventing system.

NOTICE: Failure to follow theseinstructions will void the warranty.

INSTALLATIONPRECAUTIONSConsult local building codes before beginningthe installation. The installer must make sureto select the proper vent system for installa-tion. Before installing vent kit, the installermust read this fireplace manual and vent kitinstructions.

Only a qualified service person should in-stall venting system. The installer must fol-low these safety rules:

• Wear gloves and safety glasses forprotection

• Use extreme caution when using laddersor when on roof tops

• Be aware of electrical wiring locationsin walls and ceilings

The following actions will void the war-ranty on your venting system:

• Installation of any damaged ventingcomponent

• Unauthorized modification of the vent-ing system

VENTINGINSTALLATION

WARNING: This gas fireplaceand vent assembly must bevented directly to the outside.The venting system must NEVERbe attached to a chimney servinga separate solid fuel burning ap-pliance. Each gas appliance mustuse a separate vent system. Donot use common vent systems.

WARNING: Horizontal sec-tions of this vent system require aminimum clearance of 2" from thetop of the pipe and 1" minimum tothe sides and bottom. 1 1/2" clear-ance is required where the termi-nation penetrates a combustiblewall. Vertical sections of this sys-tem require a minimum of 1" clear-ance to combustible materials onall sides of the pipe.

• Installation of any component part notmanufactured or approved by DESAInternational

• Installation other than as instructed bythese instructions

INSTALLATION PLANNINGThere are two basic types of direct-ventinstallation:

• Horizontal Termination

• Vertical Termination

It is important to select the proper length ofvent pipe for the type of termination youchoose. It is also important to note the wallthickness.

For Horizontal Termination: Select theamount of vertical rise desired. The horizon-tal run of venting must have 1/4" rise forevery 12" of run towards the termination.

NOTICE: Treatment of firestopsand construction of the chase mayvary from building type to buildingtype. These instructions are notsubstitutes for the requirementsof local building codes. You mustfollow all local building codes.

Note: When installing in a chase, you shouldinsulate the chase as you would the outsidewalls of your home. This is especially im-portant in cold climates. Minimum clear-ance between vent pipes and combustiblematerials such as insulation is 1".

After framing the chase (see Framing andFinishing on page 4) install the vent systemby following the installation instructions.

Installing Vent System in a Chase

A chase is a vertical boxlike structure builtto enclose venting that runs along the out-side of a building. A chase is not required forsuch venting.

Continued

WARNING: Never run the ventdownward as this may cause ex-cessive temperatures whichcould cause a fire.

You may use one or two 90° elbows in thisvent configuration. See Horizontal Termina-tion Configurations on pages 10 and 11.

For Vertical Termination: Measure the dis-tance from the fireplace flue outlet to theceiling. Add the ceiling thickness, the verti-

cal rise in an attic or second story, and allowfor sufficient vent height above the roofline.You may use one or two 90° elbows in thisvent configuration. See Vertical TerminationConfigurations on pages 13 and 14.

Note: You may use two 45° elbows in placeof a 90° elbow. You must follow rise to runratios when using 45° elbows.

For two-story applications, firestops are re-quired at each floor level. If an offset isneeded in the attic, additional pipe and el-bows will be required.

You may use a chase with a vent terminationwith exposed pipe on the exterior of thehouse. See Installing Vent System in a Chase,below.

Your Vanguard direct-vent fireplace hasbeen tested for a minimum 3' rise with amaximum 10" wall thickness. The maxi-mum horizontal run is 20' with 8' verticalrise (see Installation for Horizontal Termi-nation, page 8). The maximum vertical runis 30' (see Installation for Vertical Termina-tion, page 12).

It is very important that the venting systemmaintain its balance between the combus-tion air intake and the flue gas exhaust.Certain limitations apply to vent configura-tions and must be strictly followed.

8 106417



INSTALLATION FORHORIZONTAL TERMINATION1. Determine the route your horizontal

venting will take. Note: The locationof the horizontal vent termination on theexterior wall must meet all local andnational building codes and must not beeasily blocked or obstructed.

Snorkel terminations are available forterminations requiring a vertical rise onthe exterior of the building (see Figures9 and 10). Snorkel kit SVK is also avail-able (see page 15). Follow the same in-stallation procedures as used for stan-dard horizontal terminations. If install-ing the snorkel termination below grade(basement applications), you must pro-vide proper drainage to prevent waterfrom entering the snorkel termination(see Figure 10). Do not back fill aroundthe snorkel termination.

2. Rigid vent pipes and fittings have spe-cial twist-lock connections. Assemblethe desired combination of pipe and el-bows to the appliance adaptor with pipeseams oriented towards the wall or floor.

Twist-lock Procedure: The femaleends of the pipes and fittings have fourlocking lugs (indentations). These lugswill slide straight into matching slots onthe male ends of adjacent pipes and fit-tings. (All connections must be sealedwith high temperature silicone sealantas specified in the second warning onpage 7.) Push the pipe sections togetherand twist one section clockwise approxi-mately one-quarter turn until the sectionsare fully locked. See Figure 11, page 9.Note: Horizontal runs of vent must besupported every three feet. Use wallstraps for this purpose.

Flexible vent pipe must be installed withseparation spacer springs every 12". SeeFigure 11, page 9. All connections mustbe clamped tightly and sealed with hightemperature silicone sealant as specifiedin the second warning on page 7.

4. Connect a section of pipe and extendup through the hole.

Note: If an offset is needed to avoidobstructions, you must support the ventpipe every 3 feet. Use wall straps forthis purpose (see Figure 21). Wheneverpossible, use 45° elbows instead of 90°elbows. The 45° elbow offers less re-striction to the flow of the flue gasesand intake air.

5. Place the flashing over the pipesection(s) extending through the roof.Secure the base of the flashing to theroof and framing with roofing nails. Besure roofing material overlaps the topedge of the flashing as shown in Figure21. There must be a 1" clearance fromthe vent pipe to combustible materials.

6. Continue to add pipe sections until theheight of the vent cap meets the mini-mum building code requirements de-scribed in Figure 8 on page 6. Note: Youmust increase vent height for steep roofpitches. Nearby trees, adjoining rooflines,steep pitched roofs, and other similar fac-tors may cause poor draft or down-draft-ing in high winds. Increasing the ventheight may solve this problem.

7. Twist-lock the vent cap onto the lastsection of vent pipe and seal outer pipeconnection with high temperature sili-cone sealant as specified in the secondwarning on page 7.

Note: If the vent pipe passes through anyoccupied areas above the first floor, includingstorage spaces and closets, you must enclosepipe. You may frame and sheetrock the enclo-sure with standard construction material. Makesure and meet the minimum allowable clear-ances to combustibles. Do not fill any of therequired air spaces with insulation.

Cathedral Ceiling Installation1. Remove shingles or other roof cover-

ing as necessary to cut the rectangularhole for the support box. Mark the out-line of the cathedral ceiling support boxon the roof sheathing using the locat-ing hole as a center point.

2. Cut the hole 1/8" larger than the sup-port box outline (see Figure 23, page 13).

INSTALLATION FOR VERTI-CAL TERMINATION1. Determine the route your vertical vent-

ing will take. If ceiling joists, roofrafters, or other framing will obstructthe venting system, consider an offset(see Figure 21) to avoid cuttingloadbearing members. Note: Pay spe-cial attention to these installation in-structions for required clearances (airspace) to combustibles when passingthrough ceilings, walls, roofs, enclo-sures, attic rafters, etc. Do not pack airspaces with insulation. Also note maxi-mum vertical rise of the venting sys-tem and any maximum horizontal off-set limitations. Offsets must fall withinthe parameters shown in Figure 8 onpage 6.

2. Set the fireplace in desired location.Drop a plumb line down from the ceil-ing to the position of the fireplace exitflue. Mark the center point where thevent will penetrate the ceiling. Drill asmall locating hole at this point.

Drop a plumb line from the inside ofthe roof to the locating hole in the ceil-ing. Mark the center point where thevent will penetrate the roof. Drill asmall locating hole at this point.

Flat Ceiling Installation1. Cut a 10" square hole in the ceiling us-

ing the locating hole as a center point.The opening should be framed to10"x10" (254mm x 254mm) inside di-mensions, as shown in Figure 12 onpage 9 using framing lumber the samesize as the ceiling joists. If the areaabove the ceiling is an insulated ceil-ing or a room, nail firestop from thetop side. This prevents loose insulationfrom falling into the required clearancespace. Otherwise, install firestop belowthe framed hole. The firestop should beinstalled with no less than three nailsper side (see Figure 22).

2. Assemble the desired lengths of pipeand elbows necessary to reach from thefireplace flue up through the firestop.All connections must be sealed withhigh temperature silicone sealant asspecified in the second warning on page7. Be sure all pipe and elbow connec-tions are fully twist-locked (see Figure11, page 9).

3. Cut a hole in the roof using the locatinghole as a center point. (Cover any ex-posed open vent pipes before cuttinghole in roof.) The 10"x10" hole mustbe measured on the horizontal; actuallength may be larger depending on thepitch of the roof. There must be a 1"clearance from the vent pipe to combus-tible materials. Frame the opening asshown in Figure12 on page 9.

CAUTION: Use only new,black iron or steel pipe. Inter-nally-tinned copper tubing maybe used in certain areas. Checkyour local codes. Use pipe of 1/2"diameter or greater to allowproper gas volume to fireplace. Ifpipe is too small, undue loss ofpressure will occur.

Installation must include an equipmentshutoff valve, union, and plugged 1/8" NPTtap. Locate NPT tap within reach for testgauge hook up. NPT tap must be upstreamfrom fireplace (see Figure 35).

For propane/LP connection only, the in-staller must supply an external regulator.The external regulator will reduce incominggas pressure. You must reduce incominggas pressure to between 11 and 14 inches ofwater. If you do not reduce incoming gaspressure, heater regulator damage couldoccur. Install external regulator with thevent pointing down as shown in Figure 34.Pointing the vent down protects it fromfreezing rain or sleet.

Installation Items Needed

Before installing fireplace, make sure youhave 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 con-nector (if allowed by local codes) (notprovided)

* An CSA design-certified equipmentshutoff valve with 1/8" NPT tap is an ac-ceptable alternative to test gauge connec-tion. Purchase the CSA design-certifiedequipment shutoff valve from your dealer.

WARNING: A qualified ser-vice person must connect fire-place to gas supply. Follow alllocal codes.

CAUTION: For propane/LPunits, never connect heater di-rectly to the propane/LP supply.This heater requires an externalregulator (not supplied). Install theexternal regulator between theheater and propane/LP supply.

OPERATINGFIREPLACEContinued

OPERATINGOPTIONAL BLOWER

ACCESSORY

Locate the blower controls by openingthe lower louver panel on the fireplace.Blower controls are located on the leftside of the switch bracket to the left justinside the louver panel.

Both the GA3700 manual blower and theDA3610TA thermostatically-controlledblower have an ON setting and an OFFsetting. The blower will only run when theswitch is in the ON position. In the OFFposition, the blower will not operate.

Note for DA3610TA Only: If you areusing DA3610TA blower, your fireplaceand blower will not turn on and off at thesame time. The fireplace may run forseveral minutes before the blower turnson. After the heater modulates to the pilotposition, the blower will continue to run.The blower will shut off after the fireboxtemperature decreases.

The blower helps distribute heated airfrom the fireplace. Periodically check thelouvers of the firebox and remove anydust, dirt, or other obstructions that willhinder the flow of air.

OPERATINGOPTIONAL GWMS2WALL MOUNTED

SWITCHThis wall switch works just like the con-ventional light switch. Flip the switch upfor on and down for off.

Note: Make sure that this switch is not ina position to be mistaken for a light switch.This may result in the heater being inad-vertently turned on without the properprecautions being taken. See installationinstructions on page 21 of this manual.

PILOT AND BURNERS• Remove ember material before cleaning

burners and replace when cleaning iscomplete.

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

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

WARNING: Only parts sup-plied by the manufacturer shouldbe used when replacing brokenor damaged glass door panel (seeReplacement Parts , page 30). Thisglass door panel is a completeunit. No substitute materials maybe used.

CLEANING ANDMAINTENANCE

If glass has been broken, carefully removeglass door (see Removing/Replacing GlassDoor, page 21). Vacuum all glass pieceswith a shop vac.

CAUTION: Wear gloves andsafety glasses while handling orremoving broken glass. Do notremove if glass is hot. Keep chil-dren and pets away from glass.

WARNING: Do not operatefireplace with the glass door re-moved, cracked, or broken.

LOGS• If you remove logs for cleaning, refer to

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

• Use a vacuum cleaner to remove any car-bon build up on logs.

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

• Replace ember material periodically asneeded. See Replacement Parts on page 30.

VENTING SYSTEMConduct annual inspection of the ventingsystem following these guidelines:

1. Check areas of venting system that areexposed to the weather for corrosion (rustspots or streaks and, in extreme cases,holes). Have these items replaced imme-diately by a qualified service person.

2. Remove the vent cap and shine a flash-light into the vent. Remove any foreignmaterial.

3. Check for evidence of excessive con-densation. Continuous condensationcan cause corrosion of caps, pipes, andfittings and can be caused by havingexcessive lateral runs, too many elbows,or exterior portions of the system be-ing exposed to cold weather.

4. Inspect joints to verify that no pipe sec-tion or fitting has been disturbed andloosened. Check mechanical supportssuch as wall straps for rigidity.

WARNING: Turn off fireplaceand let cool before cleaning.

CAUTION: You must keep con-trol areas, burners, and circulat-ing air passageways of fireplaceclean. Inspect these areas of fire-place before each use. Have fire-place inspected yearly by a quali-fied service person. Fireplace mayneed more frequent cleaning dueto excessive lint from carpeting,bedding material, pet hair, etc.

WARNING: Do not use abra-sive cleaners as this may damageglass. Use a nonabrasive house-hold glass cleaner to clean glass.Do not clean glass when hot.

WARNING: Handle glass doorpanel with care. Do not strike,slam, or otherwise abuse glass.Do not operate fireplace with theglass door removed, cracked, orbroken.

GLASS DOOR

Glass must be cleaned periodically. Duringstart-up it is normal for condensation toform on the inside of the glass causing lint,dust, and other airborne particles to cling tothe glass surface. During initial start-up aslight film may form on the glass due topaint curing. The glass should be cleanedseveral times with a non-ammonia, non-abrasive household cleaner and warm waterafter the first two weeks of operation. There-after, clean the glass two or three timesduring each heating season, depending onthe usage and circumstances present. Referto Removing/Replacing Glass Door on page21 of this manual when removing glass doorfor cleaning.
