FRAMING
Once the final location has been determined, observing
clearances for the vent termination, you may construct framing
using dimensions shown in figures 7, 8 and 9 depending on
your particular installation. If the appliance is to be installed
directly on carpeting, tile (other than ceramic), or any
combustible material other than wood flooring, the appliance
must be installed upon a metal or wood panel extending the
full width and depth of the appliance. There are three holes on
each side of the bottom of the unit where screws can be used
to secure the unit to the floor.
The gas supply line may be connected through the side
framing or alternately through the lower sub-flooring or a
platform base if provided (see figures 10 and 11). Depending
on the installation, refer to the appropriate illustration.

GENERAL VENTING
These models are approved for use with Simpson, Dura-
Vent®, rigid type direct vent pipe as supplied by DESA or
may be used with approved types of flexible vent pipe (i.e.
ECCO-FLEX™ or ZFlex™) when appropriately sized for a 8"
outer and 5" inner diameter application.
Your Fireplace is approved for venting either horizontally
through a sidewall, or vertically through a roofline using the
following guidelines:
• Only use DESA supplied or approved types of venting
components or venting kits. Do not mix different types of vent
components, modify vent components, or custom fabricate
vent components for use in any one installation.
• Minimum clearances between vent pipes and combustible
material is 1" (25mm), except where stated otherwise.
• Combustible material may be flush with the top front of the
fireplace 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 the venting system into an attic or garage.
• Install horizontal venting with a 1/4" rise for every 12" of
run towards the termination.
• 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.
• 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 the venting
system. When using snow blowers, do not direct snow towards
vent termination area.
VENT TERMINATION CLEARANCES
The final position of your appliance depends on the location of
the vent termination in relation to the clearances that must be
observed as shown in figures 14 and 15.
You may avoid extra framing by positioning your fireplace
against an already existing framing member. The back of the
fireplace may be positioned directly against a combustible
wall.
* Check with local codes or with the current CAN/CGA B149
(.1 or .2) Installation Codes for Canada for Installations in the
USA follow the current National Fuel Gas Code, ANS Z223.1
also known as NFPA 54.

VENTING INSTALLATION
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 a vent kit, the installer must
read this fireplace manual and any vent kit instructions.
Only a qualified installer or service person should install a
venting system. The installer must follow these safety rules:
• Wear gloves and safety glasses for protection.
• Use extreme caution when using ladders or when working
on top of roofs.
• Be aware if 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. Installation other than as instructed
by these instructions.
INSTALLATION PLANNING
There are two basic types of direct-vent installations:
• Horizontal Termination
• Vertical Termination (Rigid Vent Pipe Only)
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.
Up to two 90° elbows may be used in this vent configuration.
See Horizontal Termination Configurations page 11.
Figure 14 VENT CLEARANCES
Figure 15 VENT CLEARANCES
WARNING: Read all instructions completely an
d
thoroughly before attempting installation. Failure to do so
could result in serious injury, property damage or loss o
f
life. Operation of an improperly installed and maintaine
d
venting system could result in serious injury, propert
y
damage or loss of life.
WARNING: Seal all connections with hig
h
temperature silicone every time a vent connection is made.
Before joining elbows or pipes, apply a bead of hig
h
temperature silicone sealant to the male end of the elbo
w
or pipe. High temperature silicone must also be used to re-
seal any connections after maintenance to venting system.
N
OTICE: Failure to follow these instructions will void the
warranty.
WARNING: This gas fireplace and its vent assembl
y
must be vented directly to the outside. The venting syste
m
must NEVER be attached to the chimney serving
a
separate solid fuel-
b
urning appliance. Each gas appliance
must use a separate vent system. Do not use in commo
n
vent system.
WARNING: Never run the vent downward as this
may cause excessive temperatures, which could cause
a
fire.

-8 - For more information, visit www.desatech.com
For Vertical Terminations: Measure the distance 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 up to two 90° elbows in this configuration. See
Vertical Termination Configurations on pages xx and xx.
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, fire stops 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 having exposed
pipe on the exterior of the house. See Installing Vent System
in a chase.
Your DESA direct-vent fireplace has been tested for a
minimum of 3 feet of vertical rise with accommodation for a
maximum of 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 amount of horizontal run is 20' with 8' of vertical
rise (see Installation for Horizontal Termination, page 11).
The maximum vertical run is 30' (see Installation for Vertical
Termination, page 12).
INSTALLING VENT SYSTEM IN A CHASE
A chase is a vertical box-like structure built to enclose venting
that runs along the outside of a building.
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. A minimum clearance
between vent pipes and combustible materials such as
insulation is 1".
After framing the chase install the venting system by
following the installation instructions for vertical installations
on page xx.
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 easily blocked or obstructed.
Snorkel terminations are available for terminations requiring a
vertical rise on the exterior of the building (see figures 16 and
17). Snorkel kits are available for rigid pipe applications only
to provide for a 14" rise and a 36" rise (see page 14). Follow
the same installation procedures 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 17).
Do not back fill around the snorkel termination.
2. Rigid vent-pipes and fittings have special twist-lock
connections. Assemble the desired combinations of pipe and
elbows to the appliance adapter with pipe seams oriented
towards the wall or floor.
N
OTICE: 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.
WARNING: Do not recess a vent terminal into a wall
or a siding. This will cause a fire hazard.

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 the
adjacent pipes and fittings. (All connections must be sealed
with high temperature silicone sealant as specified in the
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 18).
NOTE: Horizontal runs of vent must be supported every three
feet. Use wall strap for this purpose.
Flexible vent pipe must be installed with spacer springs every
12" and especially near each bend (See figure 19).
Make the 5" inner pipe connection to the unit with the clamp
provided. Install the spacer springs by looping them around
the 5" pipe and connecting at both ends. Slide the 8" outer
pipe over the springs and inner section and continue adding
sections in this manner. All connections need a minimum of 1
1/4" (32mm) overlap, must be clamped tightly and sealed with
high temperature silicone sealant as specified in the warning
statement on page 7.
3. Attach the vent pipe assembly to the fireplace using twist-
lock connections for rigid pipe or clamp, method for flex pipe.
See figure 20. Set fireplace in front of its permanent location
to insure minimum clearances. Mark the wall for a 10 3/4"
square hole (for non-combustible material such as masonry
block or concrete, a 8 1/2" diameter hole is acceptable). See
Figure 21. 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"
(273mm x 273mm) square hole through combustible exterior
wall (8 1/2" (216mm) diameter hole if non-combustible).
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 flex pipe applications. A round
vent termination with a slip fit connection is also provided for
rigid pipe applications, when a wall thickness or off spacing
must be accommodated. See figure 23 on page 10. Each may
be purchased as a kit, which includes a 45° elbow and a
firestop that accommodates a square or round termination.

When installing a square termination, apply a bead of non-
hardening mastic around the outside edge of the vent cap.
Position the square or the round vent cap in the center of the 8
1/2" hole on the exterior wall or in a firestop when installed
over a 12 1/2" square cutout. Make certain that the arrow on
the vent cap is pointing up after making the final connection.
If installing the square flex vent termination the square open
must be pointing up. The firestop must be used to insure that
the proper clearance of 1" to combustibles is maintained. If
using the square vent attach the vent cap with four wood
screws. If installing the round vent cap use the firestop
provided with the installation kit to accommodate the square
hole and then seal the remaining edge with mastic.
Note: Replace the wood screws with the appropriate type of
removable fasteners for stucco, brick, concrete or other types
of siding.
For vinyl siding, use vinyl siding standoffs between the vent
cap and the exterior wall. The vinyl siding standoff prevents
excessive heat from melting the vinyl siding only and must not
be used to substitute or replace a firestop. Bolt the vent cap to
the standoff. Apply non-hardening mastic around the outside
edge of the standoff instead of the vent terminal as described
earlier. Use wood screws to attach the standoff (See figure
24.)
5. There are several ways to make the final connection to the
vent terminal. If installing a flush or recessed installation with
a short vent system, you may pre-size the vent system, check
for final fit and slide the unit into the framing with the firestop
in place. This is especially helpful when using rigid pipe and a
round vent termination, as the vent may be pre-connected and
slipped through the firestop. However, you must make certain
that the 45° connection at the unit is tight and does not come
loose before finish nailing the unit to the framing.
When installing a square vent or a long vent configuration, the
vent pipe must be manipulated at the outer end to make the
final connection. This may be accomplished by manually
securing the pipe from within the open framing. However, if
this is a retrofit installation in an inaccessible space, you may
have to secure the outer end of the vent pipe with wall straps
and tap screws at the outer end.
When using tap screws with rigid pipe, make certain that the
screws do not penetrate the inner pipe. These procedures may
be followed as well for flexible pipe installations. However,
the connections at the unit must first be adequately secured,
the vent must be drawn through the end firestop, cut back to
about 6 to 8 inches to permit easy connection of the flex
termination and the termination must be slipped back into and
secured to the installation. Make sure to use an adequate
number of spring spacers at the ends and the closest bend to
the termination to prevent kinks or collapsing of the pipe. Do
not use screws with flex pipe. Remember, that the vent system
must be code inspected and released before adding dry wall or
other surface treatments.

HORIZONTAL TERMINATION CONFIGURATIONS
Figures 25 through 27 show different configurations for
venting with horizontal termination. Each figure 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
specified in the second warning statement on page 7. All
horizontal terminations require 1/4" rise per 12" of horizontal
run. Therefore, you must add 1/4" of vertical height (V) in the
following tables for each foot of horizontal run (H).
Figure 26 shows the acceptable configuration when venting
horizontally using flexible venting systems. The same vertical
height and horizontal length rules as shown in figure 25 also
applies to flex vent. However, the flex vent system must be
designed and supported to prevent restriction on the venting
system.
There should be no more than one 45° and one 90° degree
bend. All bends must be made with a minimum bend radius of
3" plus the radius of the outer pipe or as specified by the pipe
manufacturer to prevent reduction of the pipe diameter. As
with rigid pipe, flex vent must be pitched upwards and
supported without the use of screws in the vent pipe to prevent
sagging and damage.
All connections must be clamped and sealed with high
temperature silicone sealant as specified in the warning
statement on page 7.
Figure 27 shows the minimum vertical rise requirements for a
horizontal system using two 90° elbows.

INSTALLATION FOR VERTICAL TERMINATION
1. Determine the route that your vertical venting will take. If
ceiling joists, roof rafters, or other framing will obstruct the
venting system, consider an offset (see Figure 28) to avoid
cutting load bearing members.
NOTE: Pay 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 required 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 29.
2. Set the fireplace in the desired location. Drop a plumb line
down from the ceiling to the position of the fireplace exit flue.
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.
Flat Ceiling Installation
1. Cut a 12 1/2" hole in the ceiling using the locating hole as a
center point. The opening should be framed to a 12 1/2" x 12
1/2" (317.5mm x 317.5mm) inside dimensions, as shown in
Figure 29 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 topside. This prevents loose
insulation from falling into the required clearance space.
Otherwise, install firestop below the framed hole. The firestop
should be installed with the flanges set into the framing and
secured with no less than three nails per side (see figure 30).
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
8. Be sure all pipe and elbow connections are fully twist-
locked (see figure 18).
3. Cut a hole in the roof using the locating hole as a center
point. (Cover any exposed open vent pipes before cutting a
hole in the 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 19.
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 28). 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.
NOTE: Use rigid pipe only. Flex venting is not to be use
d
with a vertical termination.

5. Place the flashing over the pipe section(s) extending
through the roof. Apply a bead of silicone or roof sealer to the
bottom flange of the flashing and 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 28. There must be a 1" clearance from the
vent pipe to combustible material.
6. Continue to add pipe section(s) until the height of the vent
cap meets the minimum building code requirements described
in figure 15. Note you must increase the vent height for steep
roof pitches, nearby trees, adjoining rooflines and other
adjacent factors, which may cause poor drafting or a down-
draft condition (see figure 29). Increasing the vent height may
solve this problem.
7. Apply a bead of sealer to the upper edge of the flashing
collar and slide the storm collar over the pipe and down on the
top edge of the flashing. Apply a second bead of silicone or
roof sealer around the remaining seam of the storm collar.
Twist-lock the vent cap onto the last section of vent pipe and
seal with high temperature silicone as specified in the warning
statement on page 7. Finish sealing the flange around the
roofing material with roofing sealer.
Note: If the vent pipe passes through any occupied areas
above the first floor, including storage spaces and closets, you
must enclose the entire exposed pipe. You may frame and
sheetrock the enclosure with standard construction materials.
Make sure the enclosure meets the minimum allowable
clearances to combustibles. Do not fill any of the required air
spaces with insulation.
VERTICAL TERMINATION CONFIGURATIONS
Figures 31 through 34 show four different configurations for
vertical termination. These minimum vertical rises are based
on horizontal runs with a minimum of 1/4" upwards pitch per
foot and do not reflect constraints on a vertical system with
45° or greater offsets.
Any offset pitch of 45° or less must be considered horizontal
and sized within the maximum allowable lengths listed in the
following examples. All connections must be sealed with high
temperature silicone sealant as specified in the warning
statement on pg. 7.

WALL SWITCH INSTALLATION
The (V)DVF36TPNEA/TSTEA series uses a 24 VAC current
supplied from a transformer mounted on the ignition module
and is prewired for easy connection to a wall switch (see
figure 36). The (V)DVF36TPNA/TSTA versions use a self
generated millivolt current that allows you to activate the gas
control valve directly, without the use of normal household
electricity (see Figure 37). Both versions are supplied with a
wall switch kit for ready connection and mounting.
1. To remove the lower louvers simultaneously pull both top
end spring latches towards the center of the appliance until
they are disengaged from the locating holes. Repeat for the
bottom spring latches and pull the louvers outward ( fig. 38).
2. Connect the 18 ga. wires from the wall switch to the gas
control valve terminals marked TH and TPTH or to the
ignition module using the pigtails and wire nut connectors
supplied with the appliance.
ELECTRICAL HOOKUP FOR THE (OPTIONAL)
BLOWER ACCESSORY
Before the optional blower accessory can be operated, the
appliance outlet box must be properly connected to a standard
120 VAC power source. This must be done when the
appliance is originally installed. Refer to the Wiring Diagram
on page xx.
An outlet box with two receptacles has been provided for your
convenience and is located on the lower right side of the
appliance (see figure 39). The variable speed controller is
mounted on a magnetic base and may be positioned anywhere
within an accessible distance behind the louvered opening (see
figure 40).
You may test the blower for operation by turning the control
knob clockwise just until it clicks on, which is the full on
position. Further turning no more than 1/4 of a turn clockwise,
adjusts the fan speed to the lowest setting.
WARNING: Do wire the remote wall switch to the
main 120 VAC household supply current.

GAS LINE HOOK-UP
A manual shut-off valve has been included in the appliance’s
gas supply system. You may consider installing an extra gas
shut-off valve outside the appliance’s enclosure (check with
local codes) where it can be accessed more conveniently with
a key through a wall as shown in figure 44.
Route a 1/2” NPT GAS LINE towards the appliance coming
in from the back of the appliance. If the installation permits
you may alternately route your incoming gas line coming in
from the bottom of the appliance towards either end. It is
recommended to route the gas pipe from the back of the
fireplace if possible (see figure 45).
IMPORTANT: The appliance and its individual shut-off
valve must be disconnected from the gas supply piping system
during any pressure testing of the system at pressures in
excess of 1/2 psig. (3.5kPa). The appliance must be isolated
from the gas supply piping system by closing its individual
manual shut-off valve during any pressure testing of the gas
supply piping system at test pressures equal to or less than 1/2
psig. (3.5kPa).
1. Install a sediment trap between the incoming gas line and
the gas control valve (see figure 45). The sediment trap should
extend down the center of the pipe. Refer to your local codes.
2. Prepare incoming gas line and check with local codes
regarding the use of Teflon tape. Complete your gas line
installation by connecting the incoming gas line with the
flexible gas line. Secure tightly with a wrench and do not over
tighten.
