PRODUCT FEATURES

These are a few facts that can help you understand and enjoy your direct vent replace:

• The venting system may be routed to the outside of your home in several ways. It may vent through the roof (vertical) or it may vent to an outside/exterior wall (horizontal). The vent pipe installation is very important to allow for proper operation. You must follow the venting instructions very carefully for either vertical or horizontal applications.

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

PRE-INSTALLATION

LOCATION AND SPACE REqUIREMENTS

Determine the safest and most efcient location for your direct vent replace. 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 common locations. Be aware of all restrictions and precautions before deciding the exact location for your replace and termination cap.

When deciding the location of your replace, follow these rules:

• Do not connect this replace venting to a chimney ue serving a separate solid-fuel burning replace or appliance.

• Due to high temperatures, do not locate this replace in high trafc areas, windy or drafty areas or near furniture or draperies.

• Proper clearances must be maintained.

Flush with a wall

Through exterior wall enclosed in a chase

• Each time you turn on your replace, you may notice some amount of condensation on the inside of the replace glass. This is normal and will disappear after 10-20 minutes of operation.

• Your direct ve nt gas fire place system (replace and venting) is a balanced and sealed gas operating unit. It requires approximately 10-20 minutes of operating time before the ame pattern stabilizes.

• Models DVF-36S and DVF-36H have a standard glass inner door. Models DVF36SC and DVF-36HC have the standard glass inner door with a middle glass door and outer cool touch glass door.

• If your replace is to be installed directly on carpeting, vinyl tile or any combustible material other than wood, it must be installed on a metal or wood panel extending the full width and depth of the replace (see Figure 3).

• Your replace is designed to be used in zero clearance installations. Wall or framing material can be placed directly against any exterior surface on back, sides or top of your replace, except where standoff spacers are integrally attached. If standoff spacers are attached to your replace, these s pacer s can be plac ed directly against wall or framing material. See framing details, page 6.

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

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

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

• You may paint the termination cap with 450º F (232º C) heat-resistant paint to coordinate with the exterior nish.

• 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 and the front of outside air vent.

• Do not locate termination cap and outside air vent 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.

CLEARANCES

Minimum clearances to combustibles for the replace are as follows:

*Back and sides 0" Perpendicular walls 6" Floor 0" Ceiling to louver opening 42" Front 36" Top of Standoffs 0" Vent (See venting instructions

for specic venting

clearances.) Combustible material with a maximum thickness of 5/8" may be ush with the top front of replace.

* For back and sides of replace, do not pack with insulation or other materials. 0" clearance to combustible materials are for framing purpose only.

NOTICE: This replace is intended for use as supplemental heat. Use this replace along with your primary heating system. Do not install this replace as your primary heat source. If you have a central heating system, you may run system’s circulating blower while using replace. This will help circulate the heat throughout the house.

VENTING INSTALLATION

NOTICE: Read these instruc-

tions completely before attempting installation.

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

The venting system must terminate on the outside of the structure and can not be attached to a chimney or ue 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 following guidelines:

• 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 nish such as vinyl, wood, stucco, etc.

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

• 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.

• Have replace and selected vent components on hand to help determine the exact measurements when elbowing or offsetting. Always use wall restops when penetrating walls and restops when penetrating ceilings or attic spaces.

• For installation of replace at elevations of 4000 feet or greater, pay special attention to venting requirement recommendations.

WARNING: Read all instruc-

tions completely and thoroughly before attempting installation.

Failure to do so could result in

serious injury, property damage or loss of life.

NOTICE: Do not seal termination

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

INSTALLATION PRECAUTIONS

• Wear gl oves an d s afety glasse s f or 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:

• Ins ta llati on of an y d am aged ve nt ing component

• Unauthorized modication of the venting system (Do not cut or alter vent components)

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

Heating, LLC

• Installation other than as instructed by these instructions

WARNING: This gas replace 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 direct vent gas appliance must use a separate vent system. Do not use common vent systems.

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

NOTICE: Failure to follow these in-

structions will void the warranty.

Ve nt Opening

Noncombustible Wall

There are two basic types of direct vent installation:

• Horizontal Termination

• Vertical Termination Outside air ex installation is required for

both horizontal and vertical installation (see page 13).

Horizontal Termination Installation

IMPORTANT: Horizontal square terminations require only inner portion of wall restop. Horizontal installations using round termination require exterior portion of wall restop.

1. Set replace in its desired location and determine the route your horizontal venting will take. Do not secure replace until all venting has been installed. Some installations require sliding replace in and out of position to make nal venting connections. Figures 14 and 15 on page 12 show different congurations for venting with horizontal termination that will help you decide which application best suits your installation. Check to see if wall studs or roof rafters are in the path of your desired venting route. If they are, you may want to adjust location of replace.

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

Twist-Lock Procedure: Female ends of

pipes have locking lugs (indentations). These lugs will slide straight into matching slots on male ends of adjacent pipes. Push pipe sections together and twist one section clockwise approximately onequarter turn until sections are fully locked (see Figure 8).

Note: Horizontal runs of vent must be sup-

ported every three feet. Use wall straps for this purpose.

3. Assemble desired combination of pipe and elbows to replace ue collar. If there are long portions of venting run, pre-assembled pipe sections may be installed as subassemblies for convenience.

4. Carefully determine location where vent pipe assembly will penetrate outside wall.

VENTING INSTALLATION

Continued

Center of hole should line up with center line of horizontal vent pipe. Mark wall for

an 11 1/2" x 11 1/2" square hole. Cut and

frame square hole in exterior wall where vent will be terminated. If 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 9).

WARNING: Do not recess

vent termination into any wall. This will cause a re hazard.

5. Noncombustible Exterior Wall: Position horizontal vent cap in center of the 8 1/2" round hole and attach to exterior wall with four wood screws provided. Before attaching vent cap to exterior wall, run a bead of non-hardening mastic (pliable sealant) around outside edges to make a seal between it and outside wall.

Note: Four wood screws provided should

be replaced with appropriate fasteners for stucco, brick, concrete or other types of sidings (see Figure 10).

Combustible Exterior Wall: For vinyl

siding, stucco or wood exteriors, a siding standoff may be installed between vent cap and exterior wall. Siding standoff prevents excessive heat from damaging siding materials. Siding material must be cut to accommodate standoff. Bolt vent cap to standoff. Apply non-hardening mastic around outside edge of standoff. Position standoff/cap assembly in the center of 11 exterior wall with provided wood screws (see Figure 11). Siding standoff must sit ush against exterior fascia material.

6. Connecting Vent Cap with Horizontal Vent Pipe: Slide wall restop over vent pipe before connecting horizontal run to vent cap (see Figure 12).

Vertical Termination Installation

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

1. Determine route your vertical venting will take. If ceiling joists, roof rafters or other framing will obstruct venting system, consider an offset (see Figure 16) to avoid cutting load bearing members. Note: Pay

special 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 i ns ulation. Also note maximum vertical rise of venting system and any maximum horizontal offset limitations.

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

Drop a plumb line from inside of roof to

locating hole in ceiling. Mark center point where vent will penetrate roof. Drill a small locating hole at this point.

Flat Ceiling Installation

1. Cut a 11

/2" square hole in ceiling using locating hole as a center point. Opening should be framed to 11 1/2" x 11 1/2" inside dimensions, as shown in Figure 8 on page 9 using framing lumber the same size as ceiling joists. If area above ceiling is an insulated ceiling or an attic, nail restop from top side. This prevents loose insulation from falling into required clearance space. If area above ceiling is a living space, install restop below framed hole. Firestop should be installed with no less than three nails per side (see Figure 17).

2. Assemble desired lengths of pipe and elbows necessary to reach from replace ue up through restop. Be sure all pipe and elbow connections are fully twistlocked (see Figure 8, page 10).

3. Cut a hole in the roof using locating hole as a center point. (Cover any exposed open vent pipes before cutting hole in roof.) The 11

/2" x 11 1/2" hole must be measured on the horizontal; actual length may be larger depending on pitch of roof. There must be a 1" clearance from vent pipe to combustible materials. Frame opening as shown in Figure 9, page 10.

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

Note: If an offset is needed to avoid

obstructions, you must support vent pipe every 3 feet. Use wall straps for this purpose (see Figure 15, page 12). Whenever possible, use 45° elbows instead of 90° elbows. The 45° elbow offers less restric-

tion to the ow of ue gases.

If area above is an attic or insulated area,

install restop above framed hole.

5. Place ashing over pipe section(s) extending through roof. Secure base of ashing to roof and framing with roong nails. Be sure roong material overlaps top edge of ashing as shown in Figure 16, page 13. There must be a 1" clearance from vent pipe to combustible materials.

6. Continue to add pipe sections until height of vent cap meets the minimum building code requirements described in Figure 7 on page 7.

Note: You must increase vent height for

steep roof pitches. Nearby trees, adjoining

rooines, steep pitched roofs and other

similar factors may cause poor draft or down-drafting in high winds. Increasing vent height may solve this problem.

7. Twist-lock vent cap onto last section of vent pipe.

Note: If vent pipe passes through any occu-

pied areas above rst oor, including storage

spaces and closets, you must enclose pipe. You may frame and sheetrock enclosure with standard construction material. Make sure and meet the minimum allowable clearances

to combustibles. Do not ll any required air

spaces with insulation.

OUTSIDE AIR FLEX INSTALLATION

Outside air ex installation is required for both horizontal and vertical venting installation. There are 2 outside air ex kits available for purchase (see Parts List for Venting Kits and Components, page 15).

Construct a 8 on exterior wall (see Figure 19). Install outside air vent termination in a location that would not eventually be obstructed by bushes, snow or other obstructions. Locate outside air vent near replace to make ex duct installation easier.

HIGH ALTITUDE INSTALLATION

Your DESA Heating, LLC direct vent replace has been tested and approved for elevations from 0-2000 feet (USA).

When installing at an elevation above 2000 feet (in the USA), you may need to decrease the input rating by changing the existing burner orice to a smaller size. Reduce input 4% for each 1000 feet above sea level. Check with your local gas company for proper orice size identication.

When installing this replace at an elevation above 4500 feet, check with local authorities.

CHECK GAS TYPE

Use proper gas type for the replace unit you are installing. If you have conicting gas types, do not install replace. See retailer where you purchased the replace for proper replace according to your gas type.

INSTALLING GAS PIPING TO FIREPLACE LOCATION

WA RNING: A qual i fied service person must connect replace to gas supply. Follow all local codes.

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

gas, never connect replace to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

Installation Items Needed

Before installing replace, 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 exible gas line with gas connec-

tor (if allowed by local codes)

* A CSA design-certied equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the CSA design-certied equipment shutoff valve from your retailer.

120441-01F 15

www.desatech.com

Page 16

FIREPLACE INSTALLATION

Continued

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" of w.c. pressure. If you do not reduce incoming gas pressure, replace regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 20. 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 replace. If pipe is too small, undue loss of volume will occur.

Installation must include an equipment shutoff valve, union and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from replace (see Figure 21).

IMPORTANT: Install main gas valve (equipment shutoff valve) in an accessible location. The main gas valve is for turning on or shutting off the gas to the appliance.

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

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

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

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

21. Locate sediment trap/drip leg where it is within reach for cleaning. Install in piping system between fuel supply and replace. 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 replace gas controls. If sediment trap/drip leg is not installed or is installed wrong, replace may not run properly.

CLEANING AND MAINTENANCE

WARNING: Turn off replace

and let cool before cleaning.

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

GLASS DOORS

WARNING: Handle glass door panels with care. Do not strike, slam or otherwise abuse glass. Do not operate replace with the glass door unlatched, 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.

Figure 37 - Typical Flame Pattern

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 lm 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 rst 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 Doors, page 18 of this manual when removing glass door for cleaning.

WARNING: Only parts suppli ed by the m anufa cture r should be used when replacing broken or damaged glass door panels (see Replacement Parts, page 29). Glass door panel are complete units. 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 Doors, page 18). Vacuum all glass pieces with a shop vac.

CLEANING AND MAINTENANCE

Continued

CAUTION: Do not vacuum if

pieces are hot.

Use only glass door replacement intended for this replace (see Replacement Parts, page 29 for detail on ordering). No substitutions may be made. See Removing/Replacing Glass Doors, page 18 for instructions for replacing glass doors.

WARNING: Do not operate

replace with glass door un-

latched, removed, cracked or

broken.

PILOT AND BURNERS

• Remove 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

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

• Replace material periodically as needed. See Replacement Parts, page 29.

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 qualied service person.

2. Remove the vent cap and shine a ash-

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 ttings 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 section

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