WARNING:Thisproductcontainsand/orgenerateschemicals known to the State of California to cause cancer or birth defects or other reproductive harm.

IMPORTANT: Read this owner’s manual carefully and completely beforetryingtoassemble,operate orservicethisfireplace.Improper use of this fireplace can cause serious injury or death from burns, fire, explosion, electrical shock and carbon monoxide poisoning.

DANGER:Carbonmonoxide poisoning may lead to death!

Thisfireplacemustbeinstalledbyaqualified(cer- tified or licensed) service person. It has a sealed gas combustion chamber that uses a coaxial pipe (pipe within a pipe and having the same center) venting system. It brings in fresh air for combus- tion through the outer pipe and combustion gases are exhausted through the inner pipe. If the glass door assembly and venting pipe are not properly seated, connected and sealed, carbon monoxide leakage (spillage) can occur.

Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness or nausea. If you have these signs, the fireplace may not be working properly. Get fresh air at once! Have fireplace serviced. Somepeoplearemoreaffectedbycarbonmonoxide thanothers.Theseincludepregnantwomen,people withheartorlungdiseaseoranemia,thoseunderthe influence of alcohol and those at high altitudes.

Product Features

Theseareafewfactsthatcanhelp youunderstand and enjoy your direct-vent fireplace:

•The CD36R dedicated rear vent is best suited for flush or corner installations when vented horizontally through an exterior wall.

•The CD36T dedicated top vent is suited for any application where height is necessary to terminate the venting system either through the roof (vertical) or to gain sufficient height and offset to vent to an outside/exterior wall (horizontal).

•The vent pipe installation is very important to allow for proper operation. You must select the appropriate unit for your application and follow the venting instructions to plan your installation.

•This fireplace may be installed in any room of your house provided all local codes and these installation instructions are followed.

•Models (V)CD36R/T are equipped with a mil- livolt gas control system that does not require electricitytooperate.Apiezoignitorisprovidedto light the pilot without using matches or lighters.

•Models (V)CD36RE/TE are equipped with an electronicignitionsystemthatrequires120VAC to operate. An electrode ignitor automati- cally lights the pilot flame when the fireplace is turned on.

•All models can accept an optional circulating air blower when 120 VAC connection is sup- plied. If you plan to install an optional blower, do not forget to wire the fireplace outlet when framing.

•Each time you turn on your fireplace, you may notice some amount of condensation on the in- sideofthefireplaceglass.Thisisnormalandwill disappear after 10-20 minutes of operation.

•Yourdirect-ventgasfireplacesystem(fireplace and venting) is a balanced and sealed gas oper- ating unit. It is highly efficient because it uses outsideairforcombustionwhileindependently heating the indoor air.

Pre-Installation

Preparation

Location and space

requirements

Determine the safest and most efficient location for your DESA direct-vent fireplace. Make sure that rafters and wall studs are not in the way of the venting system. Choose a location where the heat output is not affected by drafts, air conditioning ducts, windows or doors. Figure 2 shows some commonlocations.Beawareofallrestrictionsand precautions before deciding the exact location for your fireplace and termination cap.

When deciding the location of your fireplace, follow these rules:

•Donotconnectthisfireplaceventingtoachim- ney flue serving a separate solid-fuel burning fireplace or appliance.

•Due to high temperatures, do not locate this fireplace in high traffic areas, windy or drafty areas or near furniture or draperies.

•Proper clearances must be maintained.

•If your fireplace is to be installed directly on carpeting,vinyltileoranycombustiblematerial other than wood, it must be installed on a metal orwoodpanelextendingthefullwidthanddepth of the fireplace. See Figure 3, page 6.

•Yourfireplaceisdesignedtobeusedinzeroclear- anceinstallations.Wallorframingmaterialcanbe placeddirectlyagainstanyexteriorsurfaceonthe back, sides or top of your fireplace, except where standoffspacersareintegrallyattached.Ifstandoff spacers are attached to your fireplace, these spac- ers can be placed directly against wall or framing material.

•If you plan on installing a television or enter- tainmentcenterrecessedaboveyourfireplace,it is recommended that you maintain a minimum 18" above top of louver opening.

•When locating termination cap, it is important to observe the minimum clearances shown in Figure 7, page 8.

•If recessing into a wall, you can avoid extra framing by positioning your fireplace against an already existing framing member.

•Do not recess termination cap into a wall or siding.

•You may paint the termination cap 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 util- ity 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.

Venting Installation

Instructions

NOTICE: Read these instructions completely before attempting installation.

These models are tested and approved for use with DESA (direct-vent) pipe components and terminations.

Theventingsystemmustterminateontheoutsideof the structure and can not be attached to a chimney or flue system serving a separate solid fuel or gas burning appliance. A direct-vent appliance must have its own venting system. DO NOT common vent this appliance.

These models are approved to be vented either horizontally through an outside wall or vertically through a roof or chase enclosure using the fol- lowing:

•When venting system terminates horizontally on an outside wall, you may install a standoff if the termination cap is to be installed directly on a combustible finish such as vinyl, wood, stucco, etc.

•Never run the vent downward as this may cause excessive temperatures which could cause a fire.

•Vent pipe air space clearances to combustibles are 1" on all sides except on the horizontal sections, which requires 2" clearance from the top of the pipe. Where the termination cap penetrates a combustible wall, 1" air space clearance is required.

•Havefireplaceandselectedventcomponentson handtohelpdeterminetheexactmeasurements when elbowing or offsetting. Always use wall firestops when penetrating walls and firestops when penetrating ceilings or attic spaces.

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

WARNING: Read all instructionscompletelyandthoroughly before attempting installation.

Failure to do so could result in seriousinjury,propertydamage or loss of life.

IMPORTANT: Do not seal vent cap to pipe. Cap must be removable for servicing.

NOTICE:Failuretofollowtheseinstructions will void the warranty.

NOTICE:Donotsealtermination cap to vent pipe. Cap must be removable for vent inspection and maintenance.

Installation Precautions

•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

•Unauthorizedmodificationoftheventingsys- tem (Do not cut or alter vent components)

•Installation of any component part not manufactured or approved by DESA

•Installation other than as instructed by these instructions

WARNING: This gas fireplace andventassemblymustbevented directlytotheoutside.Theventing system must NEVER be attached to a chimney serving a separate solidfuelburningappliance.Each direct-vent gas appliance must useaseparateventsystem.Donot use common vent systems.

WARNING: Vent pipe air spaceclearancestocombustibles are 1" on all sides except on the horizontalsections,whichrequire 2" clearances from the top of the pipe. Where the termination cap penetratesacombustiblewall,1" air space clearance is required.

INSTALLATION PLANNING

There are two basic types of direct-vent in- stallation:

•Horizontal Termination

•Vertical Termination

Horizontal Termination Installation

IMPORTANT: Horizontal square terminations require only inner portion of wall firestop. Hori- zontalinstallationsusingroundterminationrequire exterior portion of wall firestop (see Figure 20, page 14).

1.Setthefireplaceinitsdesiredlocationanddeter- minetherouteyourhorizontalventingwilltake. Do not secure the fireplace until all venting has beeninstalled.Someinstallationsrequiresliding thefireplaceinandoutofpositiontomakefinal venting connections. Figures 18 through 25 on pages 13 through 16 show different configura- tionsforventingwithhorizontalterminationthat willhelpyoudecidewhichapplicationbestsuits your installation. Check to see if wall studs or roof rafters are in the path of your desired vent- ingroute.Iftheyare,youmaywanttoadjustthe location of the fireplace.

2.Direct vent pipe sections and components are designed with special twist-lock connections.

Twist-Lock Procedure: The female ends of the pipes have locking lugs (indentations). These lugs will slide straight into matching slots on the male ends of adjacent pipes. Push pipe sec- tions together and twist one section clockwise approximatelyone-quarterturnuntilthesections arefullylocked(seeFigure11).Note: Horizon- tal runs of vent must be supported every three feet. Use wall straps for this purpose.

3.Any straight pipe section, a 45° or 90° elbow can be used when first connecting the venting system to the fireplace. Elbows are designed to twist-lock into any of four 90° positions to direct the venting system to the desired loca- tion. IMPORTANT: Do not attempt to alter the configuration of the elbow by cutting, twisting, bending, etc.

4.Assemblethedesiredcombinationofpipeand elbows to the fireplace flue collar. If there are long portions of venting run, pre-assembled pipe sections may be installed as subassem- blies for convenience.

5.Carefullydeterminethelocationwherethevent pipe assembly will penetrate the outside wall. The center of the hole should line up with the center-lineofthehorizontalventpipe.Markthe wall for a 10 3/4" x 10 3/4" square hole. Cut and framethesquareholeintheexteriorwallwhere the vent will be terminated. If the wall being penetrated is constructed of noncombustible material, such as masonry block or concrete, a 8 1/2" hole with zero clearance is acceptable (see Figure 12).

WARNING: Do not recess vent termination into any wall. This will cause a fire hazard.

6.Noncombustible Exterior Wall: Position the horizontal vent cap in the center of the 8 1/2" roundholeandattachtotheexteriorwallwith four wood screws provided. Before attaching the vent cap to exterior wall, run a bead of non-hardeningmastic(pliablesealant)around theoutsideedgestomakeasealbetweenitand theoutsidewall.Note: Thefourwoodscrews provided should be replaced with appropriate fasteners for stucco, brick, concrete or other types of sidings (see Figure 13).

Combustible Exterior Wall: For vinyl siding, stucco or wood exteriors, a siding standoff may be installed between the vent cap and exterior wall. The siding standoff prevents excessive heat from damaging the siding materials. Siding material must be cut to accommodate standoff. Bolt the vent cap to the standoff. Apply non-hardening mastic around outside edge of standoff. Position the standoff/cap assembly in the center of the 10 /4" square hole and attach to exterior wall with wood screws provided (see Figure 14). The siding standoff must sit flush against the exterior fascia material.3

7.Combustible Exterior Wall Only: Fittheouter and inner wall firestop into the wall before connecting horizontal run to vent cap (see Figure 15).

WARNING: Never run vent downward as this may cause excessive temperatures which could cause a fire. Operation of improperly installed and maintained venting system could resultinseriousinjury,property damage or loss of life.

Horizontal Termination Configurations

Figures 18 through 25 show different configura- tions and alternatives for venting with horizontal termination. Each figure includes a chart with criticalminimumandmaximumdimensionswhich MUST be met. IMPORTANT: Remember that a horizontal run of venting must have a 1/4" rise for every 12" of run toward the termination.

Note: Vertical restrictor must be installed in all vertical installations.

1.Determine the route your vertical venting will take. If ceiling joists, roof rafters or other framing will obstruct the venting system, consideranoffset(seeFigure26)toavoidcut- tingloadbearingmembers.Note: Payspecial attention to these installation instructions for requiredclearances(airspace)tocombustibles 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.

2.Set the fireplace in desired location. Drop a plumb line down from the ceiling to the posi- tion of the fireplace exit flue. Mark the center pointwheretheventwillpenetratetheceiling. 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.
