OWNER’S MANUAL

WARNING: Read all instruc-tions completely and thoroughlybefore attempting installation. Fail-ure to do so could result in seriousinjury, property damage or loss oflife. Operation of improperly in-stalled and maintained venting sys-tem could result in serious injury,property damage or loss of life.

WARNING: Seal all of the con-nections with high temperaturesilicone (600 °F/316° C) every timea vent connection is made. Be-fore joining elbows and pipes,apply a bead of high temperaturesilicone sealant (GE RTV 106/Loctite RTV 81585) to the end ofthe elbow or pipe. High tempera-ture silicone must also be used toreseal any connections aftermaintenance to venting system.

NOTICE: Failure to follow theseinstructions will void the warranty.

INSTALLATION PRECAUTIONSConsult 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 requirea minimum clearance of 2" fromthe top of the pipe and 1" mini-mum to the sides and bottom.Vertical sections of this systemrequire 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 thedistance 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 the house.See Installing Vent System in a Chase, below.

Your Comfort Glow direct-vent fireplacehas been 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 105455


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 CSVK is alsoavailable (see page 15). Follow the sameinstallation 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 state-ment on page 7.) Push the pipe sectionstogether and twist one section clockwiseapproximately one-quarter turn until thesections are fully locked. See Figure 11,page 9. Note: Horizontal runs of ventmust be supported every three feet. Usewall straps for this purpose.

Flexible vent pipe must be installed withspacer springs every 12". See Figure 11,page 9. All connections must be clampedtightly and sealed with high temperaturesilicone sealant as specified in the sec-ond warning statement on page 7.

3. Attach vent pipe assembly to the fire-place. Set fireplace in front of it’s perma-nent location to insure minimum clear-ances. Mark the wall for a 10" square hole(for noncombustible material such asmasonry block or concrete, a 7 1/2" diam-eter hole is acceptable). See Figure 12.The center of the hole should line up withthe center-line of the horizontal rigid ventpipe. Cut a 10"x10" (254mm x 254mm)square hole through combustible exteriorwall (7 1/2" [190mm] diameter hole if non-combustible). Frame as necessary (seeFigure 12).

Insure proper clearance of1" to combustibles is maintained. At-tach the vent cap with four wood screwssupplied (see Figure 13). Note: Re-place the wood screws with appropri-ate fasteners for stucco, brick, concrete,or other types of siding.

For vinyl siding use vinyl siding stand-offs between vent cap and exterior wall.The vinyl siding standoff prevents ex-cessive heat from melting the vinyl sid-ing material. Bolt the vent cap to thestandoff. Apply non-hardening masticaround outside edge of the standoff in-stead of the vent cap assembly. Usewood screws provided to attach thestandoff. See Figure 14.

5. Slide the wall thimble over the vent pipebefore connecting the horizontal run tothe vent cap (see Figure 15).

6. Carefully move the fireplace with ventassembly attached toward the wall andinsert the vent pipe into the horizontaltermination. The pipe overlap shouldbe a minimum of 1 1/4". Apply siliconeto the connection. Fasten all vent con-nections with screws provided. Referto Fireplace Installation on page 16 forinstructions on securing unit to fram-ing or floor.

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 with hightemperature silicone sealant as speci-fied in the second warning statementon 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 FORVERTICAL 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 state-ment on page 7. Be sure all pipe andelbow connections are fully twist-locked (see Figure 11, 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 Figure 12 on page 9.

Figure 35 - Gas Connection* The A.G.A. design-certified manual shutoff valve may be supplied with the applianceor you can purchase it from your retailer.

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 a manual shutoffvalve, union, and plugged 1/8" NPT tap.Locate NPT tap within reach for test gaugehook up. NPT tap must be upstream fromfireplace (see Figure 35).

For propane/LP connections 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.

OPERATINGOPTIONAL BLOWER

ACCESSORYLocate 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 GA3750 manual blower and theCDA3620T 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.

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.

INSPECTINGBURNERSCheck pilot flame pattern and burner flamepatterns often.

PILOT ASSEMBLYThe pilot assembly is factory preset for theproper flame height. Alterations may haveoccurred during shipping and handling. Calla qualified service person to readjust thepilot if necessary.

The height of the thermopile must be 3/8" to1/2" above the pilot flame as shown in Figure54. The thermocouple must be at a height ofabout 1/8" above the pilot flame. The flamefrom the pilot burner must extend beyondboth the thermocouple and thermopile.

If your pilot assembly does not meet theserequirements:

• turn fireplace off (see To Turn Off Gas toAppliance, page 24)

• see Troubleshooting, pages 27 through 29

BURNER FLAME PATTERNBurner flames will be steady; not lifting orfloating. Flame patterns will be differentfrom unit to unit and will vary depending oninstallation type and weather conditions.

If the vent configuration is installed incor-rectly, the flames will lift or "ghost". Thiscan be dangerous. Inspect the flames afterinstallation to ensure proper installation andperformance.

Figure 55 shows a typical flame pattern forCDV34(N/P)(A).

If burner flame pattern differs from thatdescribed:

• turn fireplace off (see To Turn Off Gas toAppliance, page 24)

PILOT AND BURNERS• Remove ember material before cleaning

burners and replace when cleaning iscomplete.

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

• Use a vacuum cleaner or small, softbristled brush 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 pieces witha 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.

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.

LOGS• If you remove logs for cleaning, refer to
