Models (V)DVF36TPNEA/TPNPEA and
(V)DVF36STEA/TSTPEA use a direct spark
ignition with a 24 VAC control module. All
models have HI/LO valve that controls the ame
height. These units can be equipped with louvers
for circulating or with panels for noncirculating
operation.
Fan Kit models DVFFBK and DVFFBKT are
available for these units as an option. If you are
uncertain as to what gas your unit is equipped for,
please check the rating plate located in the interior
of the appliance opening or consult your local
distributor of DESA products.
Early signs of
carbon monoxide poisoning resemble the u, with
headaches, dizziness or nausea. If you have these
signs, the replace may not be working properly.
Get fresh air at once! Have replace serviced.
Some people are more affected by carbon monoxide
than others. These include pregnant women, people
with heart or lung disease or anemia, those under the
inuence of alcohol and those at high altitudes.
Natural and propane/LP
gas are odorless. An odor-making agent is added to
the gas. The odor helps you detect a gas leak. How-
ever, the odor added to the gas can fade. Gas may be
present even though no odor exists.

PREPARATION
LOCATION AND SPACE
REQUIREMENTS
Determine the safest and most efcient location
for your DESA 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. Be aware of all restric-
tions and precautions before deciding the exact
location for your replace and termination cap.
When deciding the location of your replace,
follow these rules:
• A projection may be ideal for a new addition
on an existing nished wall. Refer to horizontal
termination congurations on page 15 or verti-
cal congurations on page 18.
• Do not connect this replace venting to a chim-
ney ue serving a separate solid-fuel burning
replace or appliance.
• Due to high temperatures, do not locate this
replace in high trafc areas, windy or drafty
areas or near furniture or draperies.
• Never obstruct the front opening of the appli-
ance or ow of combustion and ventilation air.
Keep control compartments accessible.
• Do not locate close to where gasoline or other
ammable liquids may be stored. The appliance
must be kept clear and free from combustible
materials.

GENERAL VENTING
These models are approved for use with DESA
58 Series, rigid type direct vent pipe as supplied
by DESA or with approved types of exible vent
pipe (not supplied) when appropriate sized for an
8" outer and 5" inner diameter application.
Your replace is approved to be vented either
through the side wall, or vertically using the fol-
lowing guidelines:
• Only use DESA supplied or approved types
of venting components or kits. Do not mix
different types of vent components, modify
vent components or custom fabricate vent
components for use in any one installation.
• Minimum clearance between vent pipes and
combustible materials is 1", except where stated
otherwise.
• Combustible material may be ush with the top
front of replace with a maximum thickness
of 3/4".
• Do not recess venting terminals into a wall
or siding.
• Do not install vent terminals below grade level.
Maintain a minimum height of 12" above snow
line.
• Do not terminate venting system into an attic
or garage.
• If using a venting conguration of only hori-
zontal venting with no vertical run, a 1/4" rise
for every 12" of run toward the termination is
required.
• 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.
VENT TERMINATION CLEARANCES
The nal position of your appliance depends on
the location of the vent termination in relation to
the clearances that must be observed as shown in
Figure 14, page 10.
You may avoid extra framing by positioning your
replace against an already existing framing mem-
ber. The back of the replace may be positioned
directly against a combustible wall.
*Check with local codes or with the CANCGA
B149 (.1 or .2) Installation Codes for Canada
for Installations. In the USA, follow the current
National Fuel Gas Fuel Gas Code, ANS Z223.1
also known as NFPA 54.

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
replace manual and vent kit instructions.
Only a qualied 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 modication of the venting system
• Installation of any component part not manu-
factured or approved by DESA
• Installation other than as instructed by these
instructions

INSTALLATION PLANNING
There are two basic types of direct-vent installation:
• Horizontal Termination
• 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
You may use one or two 90° elbows in this vent
conguration. See Horizontal Termination Con-
gurations on page 15.

VENTING INSTALLATION
INSTRUCTIONS
Continued
For Vertical Termination: Measure the distance
from the replace ue outlet to the ceiling. Add
the ceiling thickness, the vertical rise in an attic or
second story, and allow for sufcient vent height
above the roof line. You may use one or two 90°
elbows in this vent conguration. See Vertical
Termination Congurations on page 16.
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, restops are required at
each oor 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.
Your DESA direct-vent replace has been tested
for a minimum 3' rise with a maximum 11" wall
thickness. Any horizontal application longer than
12" must provide a minimum of one (1) foot of
vertical rise for every three (3) feet of horizontal run.
The maximum horizontal run is 20' with 8' vertical
rise (see Installation for Horizontal Termination).
The maximum vertical run is 30' (see Installation
for Vertical Termination, page 16).
A chase is a vertical box-like structure built to
enclose venting that runs along the outside of a
building.
and construction of the chase
-
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 insula-
tion is 1".
After framing the chase (see Framing on page 7)
install the vent system by following the installa-
tion instructions.

INSTALLATION FOR HORIZONTAL
TERMINATION
1. Determine the route your horizontal venting
will take. Note: The location of the horizontal
vent termination on the exterior wall must
meet all local and national building codes and
must not be blocked or obstructed.
WARNING: Do not recess
vent terminal into a wall or sid-
Snorkel terminations are available for termina-
tions requiring a vertical rise on the exterior of
the building (see Figures 15 and 16). Snorkel
kits are available for rigid pipe applications
only to provide a 14" rise and a 36" rise (see
page 19). Follow the same installation proce-
dures used for standard horizontal terminations.
If installing the snorkel termination to raise the
vent termination from below grade level such
as in a basement installation, you must provide
proper drainage to prevent water from entering
the snorkel termination (see Figure 16). Do not
back ll around the snorkel termination.

2. Rigid vent pipes and ttings have special
twist-lock connections. Assemble the desired
combination of pipe and elbows to the appli-
ance adaptor with pipe seams oriented towards
the wall or oor.
Twist-lock Procedure: The female ends of the
pipes and ttings have four locking lugs (in-
dentations). These lugs will slide straight into
matching slots on the male ends of adjacent
pipes and ttings. (All connections must be
sealed with high temperature silicone sealant
as specied in the second warning statement
on page 11.) Push the pipe sections together
and twist one section clockwise approximately
one-quarter turn until the sections are fully
locked. See Figure 17. Note: Horizontal runs
of vent must be supported every three feet. Use
wall straps for this purpose.
3. Attach vent pipe assembly to the replace using
twist lock connections for rigid pipe or clamp
method for ex pipe. Set replace in front of
its permanent location to insure minimum
clearances. Mark the wall for a 10 3/4" square
hole (for noncombustible material such as
masonry block or concrete, a 8 1/2" diameter
hole is acceptable). See Figure 18. The center
of the hole should line up with the centerline of
the rigid vent pipe. Cut a 10 3/4" x 10 3/4" square
hole through combustible exterior wall (8 1/2"
diameter hole if noncombustible). Frame as
necessary.

4. Three types of vent caps are available for
horizontal terminations. Two square terminals
are available; one for rigid pipe applications
and one for ex pipe applications. A round
vent termination with a slip t connection is
also provided for rigid pipe applications to
be used when a wall thickness or off spac-
ing must be accommodated. Each may be
purchased as a kit that includes a 45° elbow
and a restop that accommodates a square or
round termination (see Parts List for Venting
Kits and Components, page 19).
Apply a bead
of non-hardening mastic around the outside
edge of the vent cap. Position the vent cap in
the center of the on the exterior wall with the
arrow on the vent cap pointing up. Attach the
vent cap with four wood screws provided (see
Figure 19). Note: Replace the wood screws
with appropriate fasteners for stucco, brick,

For vinyl siding,
stucco, or wood exteriors, a siding standoff
must be installed between the vent cap and
exterior wall. The siding standoff prevents
excessive heat from damaging siding materials.
Siding materials must be cut to accommodate
standoff. Bolt the vent cap to the standoff.
Apply non-hardening mastic around outside
edge of the standoff. Position the standoff/cap
assembly in the center of the square hole and
attach to exterior wall with wood screws pro-
vided (see Figure 20). The siding standoff must
sit ush against the exterior fascia material.
5. Slide
interior wall restop over vent pipe before
connecting horizontal run to vent cap (see
Figure 21).
6. Make final connection to vent terminal.
Flush or recessed with short vent system:
Vent system may be pre-sized. Check for nal
t and slide unit into framing with restop in
place. This is helpful when using rigid pipe
and round vent termination. Vent may be
preconnected and slipped through restop.
Make sure the 45° connection at unit is tight
and does not come loose before unit is nailed
to framing.
Vent
pipe must be manipulated at outer end to make
nal connection. Manually secure pipe inside
open framing. If this is a retrot installation in
an inaccessible space, you may have to secure
the outer end of vent pipe with wall straps and
tap screws at outer end.
When using tap screws with rigid pipe, be sure
that screws do not penetrate inner pipe. These
procedures may also be followed by exible
pipe installations. To use exible pipe, vent
must be drawn through end restop, cut back
to 6"-8" to permit easy connection of ex
termination and connection must be slipped
back into and secured to installation. You
must use an adequate number of spring spac-
ers at ends and closest bend to termination to
prevent kinks or collapsing on the re. Do not
use screws with ex pipe. Vent system must
be code inspected and released before adding
dry wall or other surface treatments.

Figures 22 and 23 show different congurations for
venting with horizontal termination. Each gure
includes a chart with vertical minimum/maximum
and horizontal maximum dimensions which must
be met. All connections must be sealed with
high temperature silicone sealant as specied in
the second warning statement on page 11. All
horizontal terminations require 1/4" rise per 12"
of horizontal run. You must add 1/4" of vertical
height (V) in the following tables for each foot of
horizontal run (H).

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 24) to avoid
cutting load bearing members.

Figure 26 - Installing Firestop
If area above is a living space, install
restop below framed hole.
If area above is an attic, install restop
above framed hole.
Note: Pay special attention to these installa-
tion 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 vent-
ing system and any maximum horizontal
offset limitations. Offsets must fall within the
parameters shown in Figure 25.
2. Set the replace in desired location. Drop a
plumb line down from the ceiling to the posi-
tion 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.
1. Cut a 12 1/2" square hole in the ceiling using
the locating hole as a center point. The open-
ing should be framed to 12 1/2"x12 1/2" inside
dimensions, as shown in Figure 18 on page
13 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 insula-
tion from falling into the required clearance
space. If 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 26).
2. Assemble the desired lengths of pipe and
elbows necessary to reach from the replace
ue up through the restop. All connections
must be sealed with high temperature silicone
sealant as specied in the second warning
statement on page 11. Be sure all pipe and
elbow connections are fully twist-locked (see
Figure 17, page 13).
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
12 1/2" x 12 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 18 on page 13.
4. Connect a section of pipe and extend up
through the hole. 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 24, page 15). Whenever possible,
use 45° elbows instead of 90° elbows. The 45°
elbow offers less restriction to the ow of the
ue gases and intake air.

5. Place the ashing over the pipe section(s)
extending through the roof. Apply a bead of
silicone or roof sealer to the bottom ange of
ashing and secure the base of the ashing to
the roof and framing with roong nails. Be
sure roong material overlaps the top edge of
the ashing as shown in Figure 24, page 15.
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 14,
page 10. Note: You must increase vent height
for steep roof pitches. Nearby trees, adjoining
rooines, steep pitched roofs, and other simi-
lar factors may cause poor draft or down-draft
condition (see Figure 24, page 15). Increasing
the vent height may solve this problem.
7. Apply a bead of sealer to the upper edge of
ashing collar. Slide storm collar over pipe
and down to top edge of ashing. Apply a
second bead of silicone or roof sealer around
remaining seam of storm collar. Twist-lock
vent cap onto last section of vent pipe and
seal with high temperature silicone sealant as
specied in the second warning statement on
page 11. Finish sealing ange around roong
material with roong sealer.
Note: If the vent pipe passes through any occupied
areas above the rst oor, including storage spaces
and closets, you must enclose pipe. You may frame
and sheetrock the enclosure with standard construc-
tion material. Make sure and meet the minimum
allowable clearances to combustibles. Do not ll
any of the required air spaces with insulation.

3.
Lower the support box through the hole in the
roof until the bottom of the box extends at least 2"
below the ceiling (see Figure 27). Align the sup-
port box vertically and horizontally using a level.
Temporarily tack the support box in place through
the inside walls and into the roof sheathing.
4. Using tin snips, cut the support box from the
top corners down to the rooine and fold the
resulting aps over the roof sheathing (see
Figure 28). 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 roong nails. Remove any
combustible material that might be inside of
the support box.

HIGH ALTITUDE INSTALLATION
Your DESA direct-vent fireplace has been
tested and approved for elevations from 0-2,000
feet (USA) and elevations from 0-4,500 feet
(Canada)
Fireplaces for High Altitude (models ending in
-HA) are for installation above 4,000 feet only.
These replaces are equipped with parts specic
for higher altitudes. IMPORTANT: These re-
places can NOT be converted to propane/LP gas.
When installing a non-high altitude replace at an
elevation above 2,000 feet (USA), you may need to
decrease the input rating by changing the existing
burner orice to a smaller size. Reduce input 4%
for each 1,000 feet above sea level. Check with
your local gas company for proper orice size
identication.
When installing this fireplace at an elevation
above 4,500 feet (Canada), check with local
authorities.
IMPORTANT: For horizontal installations
above 2,000 feet, it is recommened that a 12"
extension pipe be added before starter elbow
(see Figure 33).
