PRODUCT FEATURES

These are a few facts that can help you under-

stand 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 (hori-

zontal). 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.

• 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 vent gas fireplac e system

(replace and venting) is a balanced and sealed gas operating unit. It requires ap-

proximately 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.

PREINSTALLATION

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.

• 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 the back, sides or top of your replace, except where standoff spacers are integrally attached. If standoff spac-

ers are attached to your replace, these

spacers can be placed directly against wall or framing material. See framing details on 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.

VENTING INSTALLATION

NOTICE: Read these instruc-

tions completely before attempting installation.

These models are tested and approved for

use with DESA (direct vent) pipe components

and terminations. The venting system must terminate on the

outside of the structure and can not be at-

tached 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 compo-

nents on hand to help determine the exact measurements when elbowing or offsetting.

Always use wall restops when penetrating walls and restops when penetrating ceil-

ings 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: Failure to follow these in-

structions will void the warranty.

NOTICE: Do not seal termination

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

INSTALLATION PRECAUTIONS

• We ar glo ves an d safe t y gla s ses fo r 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:

• In s tal lati on of any da mage d ven tin g 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

• 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.

INSTALLATION PLANNING

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 the replace in its desired location and determine the route your horizontal venting will take. Do not secure the replace

until all venting has been installed. Some

installations require sliding the replace in and out of position to make nal vent-

ing connections. Figures 14 and 15 on

page 11 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 the location of the replace.

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

Twist- Lo ck Procedure: The female

ends of the pipes have locking lugs (in-

dentations). These lugs will slide straight

into matching slots on the male ends

of adjacent pipes. Push pipe sections

together and twist one section clockwise

approximately one-quarter turn until the 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 the desired combination of pipe

and elbows to the replace ue collar. If

there are long portions of venting run, preassembled pipe sections may be installed as subassemblies for convenience.

4. Carefully determine the location where the vent pipe assembly will penetrate the outside wall. The center of the hole should line up with the center-line of the

horizontal vent pipe. Mark the wall for

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

frame the square hole in the exterior

wall where the vent will be terminated. If the wall being penetrated is constructed of noncombustib le material, such as masonry block or concrete, a 8 1/2" hole

with zero clearance is acceptable (see Figure 9).

VENTING INSTALLATION

Continued

WARNING: Do not recess

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

5. Noncombustible Exterior Wall: Position

the horizontal vent cap in the center of the

8 1/2" round hole and attach to the exterior wall with four wood screws provided. Before attaching the vent cap to exterior wall, run a bead of non-hardening mastic

(pliable sealant) around the outside edges

to make a seal between it and the outside wall. Note: The 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 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 11 1/2" square hole and attach to exterior wall with wood screws provided (see Fig-

ure 11). The siding standoff must sit ush

against the exterior fascia material.

6. Combustible Exterior Wall Only: Slide

the wall restop over the vent pipe before connecting horizontal run to vent cap (see Figure 12).

7. Carefully move replace, with vent as-

sembly attached, toward wall and insert

vent pipe into horizontal termination. The

pipe overlap should be a minimum of 1 1/4"

(see Figure 13, page 11).

8. Combustible Exterior Wall Only: Slide

wall restop against interior wall surface

and attach with screws provided. See Fig-

ure 13, page 11, for horizontal termination

details.

9. Place replace into position and shim with

noncombustible material if needed. Nail or

screw side anges to framing to secure unit in place. IMPORTANT: Make sure re- place is level before securing. If replace

is not level it will not work properly.

Vertical Termination Installation

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, consider an offset (see Figure 16)

to avoid cutting load bearing members. Note: Pay special attention to these instal-

lation 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.

2. Set the replace in desired location. Drop

a plumb line down from the ceiling to the

position of the replace exit ue. 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.

Roof Flashing

Wall Strap

Flat Ceiling Installation

1. Cut a 11 1/2" square hole in the ceiling using the locating hole as a center point. The 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 the ceiling joists. If the

area above the ceiling is an insulated

ceiling or an attic, nail restop from the

top side. This prevents loose insulation

from falling into the required clearance

space. Of the area above the ceiling

is a living space, install restop below the framed hole. The restop should be

installed with no less than three nails

per side (see Figure 17).

2. Assemble the desired lengths of pipe and elbows necessary to reach from the

replace ue up through the restop. Be

sure all pipe and elbow connections are

fully twist-locked (see Figure 7, 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 11 1/2" x 11 1/2" 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 Figure 9, page 9.

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 15, page 11). Whenever possible, use 45° elbows instead of 90° elbows. The 45° elbow offers less

restriction to the ow of the ue gases.

If area above is an attic or insulated area,

install restop above framed hole.

5. Place the ashing over the pipe section(s)

extending through the roof. Secure the

base of the ashing to the roof and framing with roong nails. Be sure roong

material overlaps the top edge of the

ashing as shown in Figure 16, page 12.

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 6 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 the vent height may solve this problem.

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

Note: If the vent pipe passes through any oc-

cupied areas above the rst oor, 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 ll any of the required air spaces with insulation.

Vertical Termination Congurations

Figure 17 shows the congurations for vertical

termination.

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 14).

Construct a 4 1/2" x 4 1/2" framing or opening

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 direct vent replace has been

tested and approved for elevations from 0-

2000 feet (USA) and elevations from 0-4500 feet (Canada).

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.

FIREPLACE

INSTALLATION

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

WARNI N G : A q u a li f i ed 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.

WARNING: For natural gas, ne ver connect f i 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 connector (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.

www.desatech.com

120441-01A14

Page 15

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.

Propane/LP Supply Tank

External Regulator

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 sys-

tem 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

WARNI N G : 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 lm may

form on the glass due to paint curing. The glass should be cleaned several times with a non-ammonia, nonabrasive household clean-

er 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 Door, page 17 of this manual when removing glass door for cleaning.

WARNING: Only parts supplied by the ma n u f a c t u r e r should be used when replacing broken or damaged glass door panels (see Replacement Parts, page 24). 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 17). Vacuum all glass pieces

with a shop vac.

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.

120441-01A 23

www.desatech.com

CAUTION: Do not vacuum if

pieces are hot.

Use only glass door replacement intended for

this replace (see Replacement Parts, page 24 for detail on ordering). No substitutions

may be made. See Removing/Replacing Glass Doors, page 17 for instructions for

replacing glass doors.

MAINTENANCE

Continued

WARNING: Do not operate replace with glass door unlatched, 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.

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 loos-

ened. Check mechanical supports such as wall straps for rigidity.
