OWNER’S MANUAL

VENTING
INSTALLATION

WARNING: Read all instruc­tions completely and thoroughly
before attempting installation. Fail­ure to do so could result in serious
injury, property damage or loss of
life. Operation of improperly in­stalled and maintained venting sys­tem could result in serious injury,
property damage or loss of life.

WARNING: Seal all vent con­nections. Seal only the outer pipe
connections with high temperature
silicone (600°F/316° C). Before join­ing elbows and pipes, apply a bead
of high temperature silicone seal­ant (GE RTV 106/Loctite RTV 81585)
to the male end of the elbow or
pipe. High temperature silicone
must also be used to re-seal any
connections after maintenance to
venting system.

NOTICE: Failure to follow these
instructions will void the warranty.

INSTALLATION PRECAUTIONS

Consult local building codes before begin­ning the installation. The installer must make
sure to select the proper vent system for
installation. Before installing vent kit, the
installer must read this fireplace manual and
vent kit instructions.

Only a qualified service person should in­stall venting system. The installer must fol­low these safety rules:

• 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

• Unauthorized modification of the vent­ing system

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

• Installation other than as instructed by
these instructions

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

WARNING: Horizontal sec­tions of this vent system require a
minimum clearance of 2" from the
top of the pipe and 1" minimum to
the sides and bottom. 1 1/2" clear­ance is required where termina­tion penetrates a combustible wall.
Vertical sections of this system
require a minimum of 1" clear­ance to combustible materials on
all sides of the pipe.

INSTALLATION PLANNING

There are two basic types of direct-vent
installation:

• Horizontal T ermination

• Vertical Termination
It is important to select the proper length of

vent pipe for the type of termination you
choose. It is also important to note the wall
thickness.

For Horizontal Termination: Select the

amount of vertical rise desired. The horizon­tal run of venting must have 1/4" rise for
every 12" of run towards the termination.

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

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

For Vertical Termination: Measure the dis-

tance from the fireplace flue outlet to the
ceiling. Add the ceiling thickness, the verti­cal rise in an attic or second story, and allow
for sufficient vent height above the roofline.
You may use one or two 90° elbows in this
vent configuration. See Vertical Termination
Configurations on pages 13 and 14.

Note:

You may use two 45° elbows in place
of a 90° elbow. You must follow rise to run
ratios when using 45° elbows.

For two-story applications, firestops are re­quired at each floor level. If an offset is
needed in the attic, additional pipe and el­bows will be required.

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

Your FMI direct-vent fireplace has been tested
for a minimum 3' rise with a maximum 10"
wall thickness. The maximum horizontal run
is 20' with 8' vertical rise (see Installation for
Horizontal Termination, page 8). The maxi­mum vertical run is 30' (see Installation for
Vertical Termination, page 12).

It is very important that the venting system
maintain its balance between the combus­tion air intake and the flue gas exhaust.
Certain limitations apply to vent configura­tions and must be strictly followed.

Installing Vent System in a Chase

A chase is a vertical boxlike structure built
to enclose venting that runs along the out­side of a building. A chase is not required for
such venting.

NOTICE: Treatment of firestops
and construction of the chase may
vary from building type to building
type. These instructions are not
substitutes for the requirements
of local building codes. You must
follow all local building codes .

Note:

When installing in a chase, you should
insulate the chase as you would the outside
walls of your home. This is especially im­portant in cold climates. Minimum clear­ance between vent pipes and combustible
materials such as insulation is 1".

After framing the chase (see Framing and
Finishing on page 4) install the vent system
by following the installation instructions.

INSTALLATION FOR
HORIZONTAL TERMINATION

1. Determine the route your horizontal
venting will take.
of the horizontal vent termination on the
exterior wall must meet all local and
national building codes and must not be
easily blocked or obstructed.

WARNING: Do not recess vent

terminal into a wall or siding.

Snorkel terminations are available for
terminations requiring a vertical rise on
the exterior of the building (see Figures
9 and 10). Follow the same installation
procedures as used for standard horizon­tal terminations. If installing the snor­kel termination below grade (basement
applications), you must provide proper
drainage to prevent water from entering
the snorkel termination (see Figure 10).
Do not back fill around the snorkel ter­mination.

2. Rigid vent pipes and fittings have spe­cial twist-lock connections. Assemble
the desired combination of pipe and el­bows to the appliance adaptor with pipe
seams oriented towards the wall or floor.

Twist-lock Procedure: The female
ends of the pipes and fittings have four
locking lugs (indentations). These lugs
will slide straight into matching slots on
the male ends of adjacent pipes and fit­tings. (All connections must be sealed
with high temperature silicone sealant
as specified in the second warning state­ment on page 7.) Push the pipe sections
together and twist one section clockwise
approximately one-quarter turn until the
sections are fully locked. See Figure 11,
page 9.

3. Attach vent pipe assembly to the fire­place. Set fireplace in front of it’s perma­nent location to insure minimum clear­ances. See page 10, Figure 16 for mini­mum clearances for vertical on rigid
vent pipe, and page 10 Figure 17 on
flexible vent pipe. Mark the wall for a
10" square hole (for noncombustible ma­terial such as masonry block or concrete,
a 7 1/2" diameter hole is acceptable). See
Figure 12. The center of the hole should
line up with the center-line of the hori­zontal rigid vent pipe. Cut a 10"x10"
(254mm x 254mm) square hole through
combustible exterior wall (7 1/2" [190mm]
diameter hole if noncombustible). Frame
as necessary (see Figure 12).

4. Apply a bead of non-hardening mastic
around the outside edge of the vent cap.
Position the vent cap in the center of
the 7 1/2" or 10" hole on the exterior
wall with the arrow on the vent cap
pointing up. Insure proper clearance of
1" to combustibles is maintained. At­tach the vent cap with four wood screws
supplied (see Figure 13).

Note

: Re­place the wood screws with appropri­ate fasteners for stucco, brick, concrete,
or other types of siding.

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

5. For vinyl siding use vinyl siding stand­offs between vent cap and exterior wall.
The vinyl siding standoff prevents ex­cessive heat from melting the vinyl sid­ing material. Bolt the vent cap to the
standoff. Apply non-hardening mastic
around outside edge of the standoff in­stead of the vent cap assembly. Use
wood screws provided to attach the
standoff. See Figure 14.

6. Slide the wall thimble over the vent
pipe before connecting the horizontal
run to the vent cap (see Figure 15).

7. Carefully move the fireplace with vent
assembly attached toward the wall and
insert the vent pipe into the horizontal
termination. The pipe overlap should
be a minimum of 1 1/4". Apply silicone
to the outer pipe connection. Fasten all
vent connections with screws provided.
Refer to Fir eplace Installation on page
16 for instructions on securing unit to
framing or floor.

8. Slide the wall thimble against the inte­rior wall surface and attach with screws
provided (see Figure 15).

INSTALLATION FOR
VERTICAL TERMINATION

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 20) to avoid cutting load
bearing members.
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
insulation. Also note maximum verti­cal rise of the venting system and any
maximum horizontal offset limitations.
Offsets must fall within the parameters
shown in Figure 8 on page 6.

2. Set the fireplace in desired location.
Drop a plumb line down from the ceil­ing to the position of the fireplace exit
flue. 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.

Wall Strap

Note:

45° Elbow

Pay special

Roof
Flashing

Flat Ceiling Installation

1. Cut a 10" square hole in the ceiling us­ing the locating hole as a center point.
The opening should be framed to
10"x10" (254mm x 254mm) inside di­mensions, as shown in Figure 12 on
page 9 using framing lumber the same
size as the ceiling joists. If the area
above the ceiling is an insulated ceil­ing or a room, nail firestop from the
top side. This prevents loose insulation
from falling into the required clearance
space. Otherwise, install firestop below
the framed hole. The firestop should be
installed with no less than three nails
per side (see Figure 21).

2. Assemble the desired lengths of pipe
and elbows necessary to reach from the
fireplace flue up through the firestop.
All connections must be sealed with
high temperature silicone sealant as
specified in the second warning state­ment on page 7. Be sure all pipe and
elbow connections are fully twist­locked (see Figure 11, 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 10"x10" 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 12 on page 9.

If area above is a room, install firestop
above framed hole.

If area above is not a room, install
firestop below framed hole.

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 20). Whenever
possible, use 45° elbows instead of 90°
elbows. The 45° elbow offers less re­striction to the flow of the flue gases
and intake air.

5. Place the flashing over the pipe
section(s) extending through the roof.
Secure the base of the flashing to the
roof and framing with roofing nails. Be
sure roofing material overlaps the top
edge of the flashing as shown in Figure

20. 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 8 on page 6.
must increase vent height for steep roof
pitches. Nearby trees, adjoining rooflines,
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 and seal outer pipe
connection with high temperature sili­cone sealant as specified in the second
warning statement on page 7.

Note:

If the vent pipe passes through any
occupied areas above the first floor, 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 fill any of the
required air spaces with insulation.

4. Using tin snips, cut the support box from
the top corners down to the roofline and
fold the resulting flaps over the roof
sheathing (see Figure 23). Apply a bead
of non-hardening mastic around the top
edges of the support box to make a seal
between the box and the roof. Nail in
place with roofing nails. Remove any
combustible material that might be in­side of the support box.

INSTALLING GAS PIPING TO
FIREPLACE LOCATION

WARNING: A qualified ser­vice person must connect fire­place to gas supply. Follow all
local codes.

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

Installation Items Needed

Before installing fireplace, 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 flexible gas line with gas con­nector (if allowed by local codes) (not
provided)

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

For propane/LP connections 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 inches of
water. If you do not reduce incoming gas
pressure, heater regulator damage could
occur. Install external regulator with the
vent pointing down as shown in Figure 33.
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 fireplace. If
pipe is too small, undue loss of
pressure 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 fireplace (see Figure 34).

IMPORTANT:

valve in an accessible location. The equip­ment shutoff 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 fireplaces.

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

CAUTION: 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 34. Locate sediment trap/drip leg
where it is within reach for cleaning. Install

Install equipment shutoff

in piping system between fuel supply and

OPTIONAL BLOWER

ACCESSORY

Locate the blower controls by opening
the lower louver panel on the fireplace.
Blower controls are located on the left
side of the switch bracket to the left just
inside the louver panel.

Both the GA3700 manual blower and the
DA3610TA thermostatically-controlled
blower have an ON setting and an OFF
setting. The blower will only run when the
switch is in the ON position. In the OFF
position, the blower will not operate.

Note for DA3610TA Only:

using DA3610TA blower, your fireplace

same time. The fireplace may run for
several minutes before the blower turns
on. After the heater modulates to the pilot
position, the blower will continue to run.
The blower will shut off after the firebox
temperature decreases.

The blower helps distribute heated air
from the fireplace. Periodically check the
louvers of the firebox and remove any
dust, dirt, or other obstructions that will
hinder the flow of air.

If you are

INSPECTING
BURNERS

BURNER FLAME PATTERN

Burner flames will be steady; not lifting or
floating. Flame patterns will be different
from unit to unit and will vary depending on
installation type and weather conditions.

If the vent configuration is installed incorrectly,
the flames will lift or “ghost”. This can be
dangerous. Inspect the flames after installation
to ensure proper installation and performance.

Figure 53 shows a typical flame pattern for
DVFE34 models.

If burner flame pattern differs from that
described:

• turn fireplace off (see T o T urn Off Gas to

CLEANING AND
MAINTENANCE

WARNING: Turn off fireplace

and let cool before cleaning.

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

GLASS DOOR

WARNING: Handle glass door
panel with care. Do not strike,
slam, or otherwise abuse glass.
Do not operate fireplace with the
glass door 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.

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 film 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 first 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 on page
21 of this manual when removing glass door
for cleaning.

WARNING: Only parts sup­plied by the manufacturer should
be used when replacing broken
or damaged glass door panel (see

Replacement Parts

glass door panel is a complete
unit. 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
Door, page 21). Vacuum all glass pieces with
a shop vac.

CAUTION: Do not vacuum if
pieces are hot.

Use only the glass door replacement in­tended for this fireplace (see Replacement
Parts, page 30 for detail on ordering). No
substitutions may be made. See Removing/
Replacing Glass Door, page 21 for instruc­tions for replacing glass door.

WARNING: Do not operate
fireplace with the glass door re­moved, cracked, or broken.

PILOT AND BURNERS

• Remove ember 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

• If you remove logs for cleaning, refer to

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

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

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

• Replace ember material periodically as
needed. See Replacement P arts on page 30.

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 qualified service person.

2. Remove the vent cap and shine a flash-

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
fittings 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 sec-

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

Always specify model and serial numbers when communicating with the factory.
We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our standard written warranty.

We make no other warranty, expressed or implied.

LIMITED WARRANTY

DIRECT-VENT FIREPLACE

DESA International warrants this product to be free from defects in materials and components for two (2) years from the date of first
purchase, provided that the product has been properly installed, operated and maintained in accordance with all applicable instructions.
To make a claim under this warranty the Bill of Sale or cancelled check must be presented.

This warranty is extended only to the original retail purchaser. This warranty covers the cost of part(s) required to restore this heater to
proper operating condition and an allowance for labor when provided by a DESA Authorized Service Center. Warranty part(s) MUST
be obtained through authorized retailers of this product and/or DESA International who will provide original factory replacement parts.
Failure to use original factory replacement parts voids this warranty. The heater MUST be installed by a qualified installer in accordance
with all local codes and instructions furnished with the unit.

This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail or become
damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by improper installation. Travel, diagnostic cost,
labor, transportation and any and all such other costs related to repairing a defective heater will be the responsibility of the owner.

TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE OF THE PRODUCT;
THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED WARRANTIES AND LIMITS THE DURA­TION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE TO TWO (2) YEARS ON ALL COMPONENTS FROM THE DATE OF FIRST PURCHASE; AND
DESA INTERNATIONAL’S LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA
INTERNATIONAL SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT,
INCIDENTAL OR CONSEQUENTIAL DAMAGES.

Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental or consequential
damages, so the above limitation on implied warranties, or exclusion or limitation on damages may not apply to you.

This warranty gives you specific legal rights, and you may also have other rights that vary from state to state.
