IMPORTANT:
PLEASE REVIEW THE FOLLOWING CAREFULLY
Remove any plastic from parts before turning the fire-
place ON.
It is normal for fireplaces fabricated of steel to give off
some expansion and/or contraction noises during the
start up or cool down cycle. Similar noises are found
with your furnace heat exchanger or car engine.
It is not unusual for your gas fireplace to give off some
odor the first time it is burned. This is due to the curing
of the paint and any undetected oil from the manufac-
turing process.
Please ensure that your room is well ventilated-
open all windows.
It is recommended that you burn your fireplace for at
least ten (10) hours the first time you use it.
This appliance has been designed, certified and ap-
proved to be installed indoors only.
WARNING: Check with your electronics manufacturer
before installing a television or other electronic de-
vice above this fireplace.
13. This fireplace must not be connected to a chimney flue
serving a separate solid fuel burning fireplace.
14. When the fireplace is not in use it is recommended that the
gas control valve be left in the “OFF” position.
15. For operation during power outages, the installation
of the optional battery back-up kit Model DVTBBK is
recommended at initial installation.

A hearth is not mandatory but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth which projects out 12” (305 mm) or more from
the front of the fireplace. The hearth cannot exceed 1¹⁄₂”
(38mm) in height from bottom of fireplace for ease of
door accessibility. (Fig. 5)
Cold climate installation recommendation:
When installing this unit against a non-
insulated exterior wall or chase, it is
mandatory the outer walls be insulated to
conform to applicable insulation codes.
If a vapor barrier is used it can not come into
contact with fireplace.
Hearth
Framing and Finishing
1. Choose the unit location.
2. The unit is shipped with four (4) nailing flanges
mounted to the sides near the front corners. (Fig. 5)
3. Frame the fireplace with a header across the top of
the standoff. (Fig. 6) It is very important to allow for
the finished wall face along with marble, tiles or any
other noncombustible face finish material desired
when setting the depth of the framing.
Final Finishing
Noncombustible materials such as brick or tile may be
brought to the edges of the face of the appliance.

4. Attach the fireplace nailing flanges to the frame as
shown in Figure 5.
5. The gas components are located in the control panel
assembly attached to the right side of the unit. (Fig.
5)
6. The U-channel located on the top of the unit as well
as the nailing flanges on the sides that were men-
tioned in Step 1, are designed to accommodate non-
combustible board (recommended Dura-Rock). They
are positioned 1” (25mm) back from the face of the
unit. NOTE: The U-channel depth can be adjusted
by loosening the hex nut inside the channel.
If marble, tile or any other noncombustible decora-
tive face finish material is desired, a 3” (76 mm) wide
noncombustible board (recommended Dura-Rock)
is to be nailed to the nailing flanges on both sides
of the unit. Also, 12” (305 mm) of noncombustible
board is to be nailed to the front face of the U-chan-
nel and the top framing member above the standoff.
Combustible material can then be brought to the
outside edges of the noncombustible board installed
earlier. Any noncombustible decorative face finish
could be brought to the sides and top of the unit and
can cover the framing and sheet rock. If a decora-
tive facing is not desired, then the noncombustible
boards must be double thickness and brought flush
with the face of the unit.

When purging gas line the front glass must
be removed.
A gas shut off valve must be installed on
the gas pipe line going into the appliance
within easy access. Refer to local codes.
The gas pipeline can be brought in through the top of
the valve box assembly.
The gas line connection can be made with properly
tinned 1/2” copper tubing or 1/2” gas tight. Some
municipalities have additional local codes, it is always
best to consult your local authority and the CSA-B149.1
installation codes.
For USA installations consult the current National Fuel
Gas Code, ANSI Z223.1/NFPA 54.
Always check for gas leaks with a mild
soap and water solution applied with a
brush no larger than 1” (25 mm). Never
apply soap and water solution with a spray
bottle. Do not use an open flame for leak
testing.
The fireplace valve must not be subjected
to any test pressures exceeding 1/2 psi.
Isolate or disconnect this or any other gas
appliance control from the gas line when
pressure testing.
The fireplace is equipped with an inlet and manifold
pressure test point, therefore it is not necessary to pro-
vide a 1/8” test point up stream of the control.
When using copper, use only approved fittings. Always
provide a union when using black iron pipe so the gas
line can be easily disconnected for burner servicing. A
union may not be behind a wall. Refer to the gas speci-
fications for pressure details and ratings.

Operational Notes:
The Thermostatic feature on the transmitter operates the appliance whenever the ROOM TEMPERATURE varies a
certain number of degrees from the SET TEMPERATURE. This variation is called the “SWING” or TEMPERATURE
DIFFERENTIAL. The normal operating cycle of an appliance may be 2-4 times per hour depending on how well the
room or home is insulated from the cold or drafts. The factory setting for the “swing number” is 2. This represents a
temperature variation of +/- 2° F (1° C) between SET temperature and ROOM temperature, which determines when
the fireplace will be activated. This function is pre-set at the factory.
The transmitter has ON and OFF manual functions that are activated by pressing either button on the face of the
transmitter. When a button on the transmitter is pressed the word “ON” or “OF” will appear on the LCD screen to show
while the signal is being sent. Upon initial use, there may be a delay of three seconds before the remote receiver will
respond to the transmitter. This is part of the system’s design.
NOTE: The fireplace receiver will only respond to the transmitter when the 2-position slide button on the module is
in the REMOTE position. If the system does not respond to the battery transmitter on initial use, refer to MATCHING
SECURITY CODES, and recheck battery positions in the remote receiver.
Thermostatic Updating Feature
This remote control has a THERMOSTATIC UPDATING feature built into its software. The THERMOSTATIC UPDAT-
ING feature operates in the following manner, while in the THERMOSTATIC mode.
The transmitter reads the ROOM temperature every 2 minutes checking the ROOM temperature against the SET
temperature and then sends a signal to the receiver.

with 315°F high temperature metal adhesive tape for
proper sealing.
Start by attaching the first vent pipe section to the collar
on top of the fireplace. In order to attach the first pipe
section, it may be necessary to remove the top shield.
Remove four (4) screws securing top shield, install first
pipe section and replace top shield.
Install the pipe as shown in Figure 15. When you get a
good lock, you will hear the pipe clearly snap together.
Once sections are snap-locked in place, it is extremely
difficult to get them apart. Make sure the pipe is firmly
snapped and locked together as each pipe section is
mounted. When using 45° or 90° elbows, it is accept-
able to use three (3) screws (not supplied) at the joint
between the vertical SK8 pipe and the elbow to ensure
no separation.
When installing elbows, follow the same procedure.
The joints of inner and outer elbow must be taped with
UL approved high temperature metal adhesive tape for
proper sealing. Be sure to always attach straps on up-
per elbow to a structural framing member.
For vertical installations, continue installing the pipe as
required until pipe is installed up through the ceiling. At
this point, you must install a firestop spacer.

Since it is very important that the vent-
ing system maintain its balance between
the combustion air intake and the flue
gas exhaust, certain limitations as to vent
configurations apply and must be strictly
adhered to.
NOTE: The penetration to the outside of the build-
ing or structure shall be sealed air and weather
tight.
Use of the Restrictor Plates in
Horizontal Venting Applications
The primary purpose for the vent restrictor plate is to
regain flame height under certain venting conditions as
outlined below.
The DVT38IN is shipped with the fresh air plate set-
tings at #4 (this applies to both natural gas and
propane) when using the horizontal starter vent kit
SK8DVSK.
Minimum clearance between vent pipes
and combustible materials is 3¹⁄₂” (89 mm)
on top, 2¹⁄₂” (64 mm) on both sides and 1¹⁄₂”
(38 mm) on the bottom.
When the vent termination exits through foundations
less than 20” (508 mm) below siding outcrop, the vent
pipe must be flush with the siding.
It is always best to locate the fireplace in such a way
that minimizes the number of offsets and horizontal
vent length of vent pipe from the flue collar of the fire-
place to the face of the outer wall.
Horizontal plane means no vertical rise exists on this
portion of the vent assembly.
NOTE: Apply high temperature sealant or UL approved
high temperature metal adhesive tape as directed on Page
12.

• The maximum number of 45° elbows permitted per
side wall installation is two (2). These elbows can be
installed in either the vertical or horizontal run. (Fig.
19)
• For each 45° elbow installed in the horizontal run,
the length of the horizontal run MUST be reduced by
18” (45 cm). This does not apply if the 45° elbows
are installed on the vertical part of the vent system.
For each 90° elbow installed in the horizontal run,
the length of the horizontal run MUST be reduced by
36” (914 mm).
• The maximum number of elbow degrees in a system
is 270°. (Fig. 20)

STEP 1
Locate vent opening on the wall. It may be necessary
to first position the fireplace and measure to obtain hole
location. Depending on whether the wall is combustible
or noncombustible, cut opening to size. (Fig. 21)
For combustible walls first frame in opening.
Combustible Walls: Cut a 16¹⁄₄”h x 16¹⁄₄” w (413 mm x
413) hole through the exterior wall and frame as shown.
Noncombustible Walls: Hole opening must be 11¹⁄₄”
(286 mm) in diameter.
STEP 2
Sidewall Installation
Measure wall thickness and cut zero clearance sleeve
parts to proper length (MAXIMUM 12”/305 mm). As-
semble sleeve using #8 sheet metal screws (supplied).
(Fig. 22) Install firestop assembly. (Fig. 31)
Zero clearance sleeve is only required for
combustible walls.
