IMPORTANT SAFETY INFORMATION

23015-3-0707Page 4
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must find out if you
can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors
in the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling a
gas odor can make it easier to smell.
The odorant in LP-Gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can filter the odorant. Odorants
in LP-Gas also are subject to oxidation. This fading can occur if
there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into walls,
masonry and other materials and fabrics in a room. That will take
some of the odorant out of the gas, reducing its odor intensity.
LP-Gas may stratify in a closed area, and the odor intensity could
vary at different levels. Since it is heavier than air, there may be
more odor at lower levels. Always be sensitive to the slightest gas
odor. If you detect any odor, treat it as a serious leak. Immediately
go into action as instructed earlier.
Propane (LP-Gas) is a flammable gas which can cause fires
and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precau-
tions which can protect both you and your family from an
accident. Read them carefully now, then review them point
by point with the members of your household. Someday
when there may not be a minute to lose, everyone’s safety
will depend on knowing exactly what to do. If, after read-
ing the following information, you feel you still need more
information, please contact your gas supplier.
• Learn to recognize the odor of LP-Gas. Your local LP-Gas
Dealer can give you a “Scratch and Sniff” pamphlet. Use it to
find out what the propane odor smells like. If you suspect that
your LP-Gas has a weak or abnormal odor, call your LP-Gas
Dealer.
• If you are not qualified, do not light pilot lights, perform service,
or make adjustments to appliances on the LP-Gas system. If
you are qualified, consciously think about the odor of LP-Gas
prior to and while lighting pilot lights or performing service
or making adjustments.
• Sometimes a basement or a closed-up house has a musty smell
that can cover up the LP-Gas odor. Do not try to light pilot
lights, perform service, or make adjustments in an area where
the conditions are such that you may not detect the odor if
there has been a leak of LP-Gas.
• Odor fade, due to oxidation by rust or adsorption on walls of
new cylinders and tanks, is possible. Therefore, people should
be particularly alert and careful when new tanks or cylinders
are placed in service. Odor fade can occur in new tanks, or
reinstalled old tanks, if they are filled and allowed to set too
long before refilling. Cylinders and tanks which have been
out of service for a time may develop internal rust which will
cause odor fade. If such conditions are suspected to exist, a
periodic sniff test of the gas is advisable. If you have any
question about the gas odor, call your LP-Gas dealer. A
periodic sniff test of the LP-Gas is a good safety measure
under any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
• If you experience a complete “gas out,” (the container is under
no vapor pressure), turn the tank valve off immediately. If the
container valve is left on, the container may draw in some air
through openings such as pilot light orifices. If this occurs,
some new internal rusting could occur. If the valve is left
open, then treat the container as a new tank. Always be sure
your container is under vapor pressure by turning it off at the
container before it goes completely empty or having it refilled
before it is completely empty.
• Do not operate electric switches, light matches, use your phone.
Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such as
basements. When you have reason to suspect a gas leak, keep
out of basements and other low areas. Stay out until firefighters
declare them to be safe.
• Use your neighbor’s phone and call a trained LP-Gas service
person and the fire department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
SOME POINTS TO REMEMBER
NO ODOR DETECTED - ODOR FADE
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That’s your signal to go into immediate action!

The gas pipeline can be brought in through the right or left side of
the appliance. The insert has a Flexline with shutoff valve located
on the right side when facing the unit. See Figures 5 and 6. Consult
the current National Fuel Gas Code, ANSI Z223.1 CAN/CGA-B149
(.1 or .2) installation code.
Installing the Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of the
unit. Where none exists, or where its size or location is not ad-
equate, contact your local authorized installer for installation or
relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liquefied petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed flame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
NOTE: The millivolt gas controls are equipped with a captured
screw type pressure test point, therefore it is not necessary to provide
a 1/8" test point up stream of the control.
When using copper or flex connector use only approved fittings.
The appliance and it’s individual shut off valve must be disconnected
from supply piping system during any pressure testing of that system
at test 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).
Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the fireplace gas valve, it will
result in a hazardous condition.
Checking Manifold Pressures
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressure of approximately 3.5" w.c. (.871kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 4.5" w.c.
(1.120kPa) for the purpose of input adjustment to a maximum of
14.0" w.c. (3.484kPa). Propane gas models will have a manifold
pressure approximately 10.0" w.c. (2.49kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 10.8" w.c.
(2.68kPa) for the purpose of input adjustment to a maximum of
14.0" w.c. (3.484kPa).

Note: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings.
— ANS Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction. The state of Massachusetts requires that a flexible
appliance connector cannot exceed three feet in length.

VENTING AND INSTALLATION
1. Before beginning, remove glass door and log package from
unit. Also check to make sure there is no hidden damage to
the unit. Take a minute and plan out the gas, venting and elec-
trical route. It is best to start with the gas line first, followed
by the chimney liner and electrical supply requirements.
2. Minimum fireplace opening requirements are shown in
Figure 2 of this installation manual. The firebrick (refrac-
tory), glass doors, screen rails, screen mesh and log grates
can be removed from a factory built fireplace in order to gain
minimum gas insert opening requirements prior to installing
the gas fireplace insert.
3. This insert requires no hearth extensions. Combustible ma-
terial on the floor may be installed up to the insert. Do not
obstruct the lower louver of the insert. The original fireplace
cannot be returned to solid fuel in this condition.
4. The metal floor of the solid fuel firebox may be removed to
facilitate the installation of the insert. CLEARANCE TO
COMBUSTIBLE MATERIAL UNDER THE INSERT IS
1/4”. YOU MUST USE THE LEVELING LEGS TO RAISE
THE INSERT A MINIMUM OF 1/4” IF THE INSERT IS
TO SIT ON COMBUSTIBLE MATERIAL. The side walls
and top structure of the firebox may not be altered with the
exception of removable baffles and dampers. Smoke shields,
shelves and baffles may be removed if attached with me-
chanical fasteners. The original fireplace cannot be returned
to solid fuel in this condition.
5. Combustible facing material may be installed over the
original combustible facing material on the solid fuel fire-
place. The original specified clearances of a factory-built
fireplace must be maintained, with the exception of the
hearth. Clearances on a masonry fireplace must be main-
tained at 12” from the opening for combustible projections
over 1 1/2”. Clearances for combustible projections under
1 1/2” must be maintained at 6” from the opening per
NFPA211. Plan the surround size accordingly. A surround
must be used with the insert. UNDER NO CIRCUMSTANCE
CAN COMBUSTIBLE MATERIAL BE PLACED BEHIND
THE SURROUND!
6. The insert surround is tested and approved with this gas insert
and may cover existing air circulation vents or grills on the
solid fuel fireplace it is installed into. If the surround does
not cover the entire ventilation grill surface, the exposed grill
area should be left open.
NOTE: Surround panel kits have been tested and approved to
cover existing air circulation vents or grills.
NOTE: Cutting of sheet metal parts of a fireplace in order to
install the fireplace insert is prohibited.
WARNING: Only the surround as supplied may be used
to cover integral grills on the solid fuel-burning fireplace.
No other components such as shrouds, sheet metal plates,
etc. may be used to seal off vents.
7. To assure top performance, safety and efficiency, inserts must
be installed with an approved flue liner as per CAN/CGA
B-149 or National Fuel Code ANSI Z223 and these instruc-
tions.
Note: The following statement is also provided on a separate
label plate in the instruction packet. Prior to installation of
the fireplace insert, the installer must mechanically secure this
warning plate to the inside of the fireplace for future reference
as required.
WARNING: The solid fuel fireplace has been converted
for use with gas only and cannot be used for burning wood
or solid fuels unless all original parts have been replaced
and the fireplace has been reapproved by the authority
having jurisdiction.
8. The solid fuel fireplaces’ flue damper must be fully locked
in the open position or removed for installation of the gas
fireplace insert.
9. The fireplace and fireplace chimney must be cleaned and in
good working order and constructed of noncombustible ma-
terials.
10. Make sure that all chimney cleanouts fit properly so air can-
not leak into the chimney.
11. Install the insert without the surround panels attached and
make all gas, venting, and electrical connections.
If the factory built fireplace does not have gas access holes
provided, an access hole of 1 1/2” diameter (37.5mm) or
less may be drilled through the lower sides or bottom of
the firebox in a proper workmanship like manner. This
access hole must be plugged with a non-combustible insu-
lation after the gas supply line has been installed.
12. To complete the installation, install surround panel assembly.
Please refer to instructions included with the surround panel
kit.
Ensure there are no obstructions to side air passages of
decorative trim once installed on insert.

VENTING AND INSTALLATION
Vent System Approvals
Figure 8 shows the vent termination caps and systems approved
for use with these models. Approved vent system terminations
are labeled for identification. 3-inch diameter listed flexible
aluminum or stainless steel gas vent is used for both the incoming
combustion air and exhaust vent pipes. NO OTHER VENTING
SYSTEMS OR COMPONENTS MAY BE USED. Detailed
installation instructions are included with each vent termination
kit and should be used in conjunction with this manual.
Horizontal Venting
The vent system on this model CANNOT be terminated
horizontally.
Vertical Venting
The inlet and exhaust vent pipes MUST be connected to the
proper collars on the unit AND to the termination cap or the unit
will not operate. The intake vent collar is identified by a stamped
“I” on the top collar sliding vent plate assembly.
WARNING: MAJOR U.S. BUILDING CODES SPECIFY
MINIMUM CHIMNEY AND/OR VENT HEIGHT
ABOVE THE ROOF TOP. THESE MINIMUM HEIGHTS
ARE NECESSARY IN THE INTEREST OF SAFETY.
SEE FIGURES 8 THROUGH 10 FOR MINIMUM
HEIGHTS, PROVIDED THE TERMINATION CAP IS
AT LEAST 2-FEET FROM A VERTICAL WALL AND
2-FEET BELOW A HORIZONTAL OVERHANG.
Note: This also pertains to vertical vent systems installed on the
outside of the building.
WARNING: THE EXHAUST PIPE MUST ONLY
BE CONNECTED TO THE EXHAUST STARTING
COLLAR OF THE UNIT AND TO THE EXHAUST
COLLAR OF THE TERMINATION CAP.
THE INLET AIR PIPE MUST ONLY BE CONNECTED
TO THE INLET AIR STARTING COLLAR OF THE
UNIT AND TO THE INLET AIR COLLAR OF THE
TERMINATION CAP. BOTH THE INLET VENT AND
THE FLUE VENT MUST BE CONNECTED FROM
THE INSERT TO THE VENT TERMINATION CAP.
NOTE: The minimum vertical vent rise is 12 feet and the
maximum vertical vent rise is 35 feet. These dimensions are
measured from the starting collars of the unit to the end of the last
section of vent pipe. See Figure 8.
NOTE: The damper of the masonry chimney may need to be
removed to allow installation of the flexible-vent pipe.
When installing into a zero clearance, factory built wood-burning
fireplaces, the use of the DVKI Round Vertical Termination Kit
should allow you to mount the vent adaptor and cap to the exposed
round chimney pipe easily.
Connecting the Vent Pipe
Caution: Sharp edges. Always use gloves when installing.
Install the 3-inch flexible vent pipes down through the chimney.
Attach the pipe-to-cap adaptor to the termination cap and the
top of the flexible vent pipe, then install the cap to the top of the
chimney.
Remove the vent slide plate assembly from the top of the insert.
See Figure 7. Trim off excess venting then attach and secure
the bottom ends of the flex pipes to the starting collars with the
adjustable band clamps provided. Slide the gas insert into place,
and position any excess flex vent pipe back up into the chimney.
Begin installation of the insert into the fireplace opening. Align
the vent slide plate assembly with the guides located on top of
the insert. Work the insert inch by inch into the fireplace cavity
as you pull forward on the vent slide plate assembly. Do not use
excessive force on the vent slide plate. Once the vent slide plate
is close to seating, install the vent bolt through the center hole
of the insert top flange, and into the vent slide plate nut. Using
a wrench or socket, tighten the bolt until the vent slide plate is
seated forward completely.
Positioning, Leveling, and Securing Insert
1. Place the insert into position.
Note: The front flanges of the insert (without surround panels)
should be set at approximately 1”(inch) in front of the face of the
fireplace.
2. Level the insert from side to side and front to back.
3. If necessary, use the leveling bolts included in the instruction
pack. Screw the legs into the nuts installed in the bottom of
the insert. Turn legs in until insert is level.
CAUTION: TO AVOID DOWNDRAFTS AND/OR COLD AIR
PROBLEMS, IT IS RECOMMENDED TO SEAL OFF THE
AREA BETWEEN THE TERMINATION CAP AND THE TOP
OF THE SOLID-FUEL CHIMNEY OPENING INTO WHICH
THE VENT CAP HAS BEEN INSTALLED.

Vertical Through the Roof Applications
The Gas Fireplace Insert has been approved for:
a) Vertical installations up to 35 feet in height (top of insert to
cap).
b) Two sets of 45 degree elbow offsets (bends in flexvent) within
the vertical installation. From 0 to a maximum of 8 ft. of vent
pipe can be used between elbows.
c) Wall straps must be used to support offset pipe every 4'.
This application will require that you first determine the roof pitch
and use the appropriate venting components.
General Maintenance
Conduct an inspection of the venting system semi-annually.
Recommended areas to inspect are as follows:
1. Check areas of the venting system which are exposed to the
elements for corrosion. These will appear as rust spots or
streaks and, in extreme cases, holes. These components should
immediately be replaced.
2. Remove the cap and shine a flashlight down the vent. Remove
any bird nests or other foreign material.
3. Check for evidence of excessive condensate, such as water
droplets forming in the flex venting and subsequently dripping
out at joints or seams. Condensate can cause corrosion of caps,
pipe and fittings. It may be caused by having excessive lateral
runs, or having exterior portions of the system exposed to cold
weather.
4. Inspect joints to verify that no pipe sections or fittings have been
disturbed and, consequently, loosened. Also, check mechanical
supports, such as wall straps or plumbers’ tape for rigidity.
Determining Minimum Vent Height Above the Roof.
WARNING: Major U.S. building codes specify minimum
chimney and/or vent height above the roof top. These minimum
heights are necessary in the interest of safety. These specifica-
tions are summarized in Figure 9.
Figure 9
Note that for steep roof pitches, the vent height must be increased.
In high wind conditions, nearby trees, adjoining roof lines, steep
pitched roofs, and other similar factors can result in poor draft,
or down-drafting. In these cases, increasing the vent height may
solve this problem.
When terminating the vent cap near an exterior wall or overhang,
maintain minimum clearances as shown in Figure 10.

of the grate tang uprights. The bottom of the two front logs are flat and
must sit on top of the front log support ledge.
Before you begin: This fireplace insert is supplied with a set of seven ce-
ramic fiber logs. Do not handle these logs with your bare hands. Always
wear gloves to prevent skin irritation from ceramic fibers. After handling
logs, wash your hands gently with soap and water to remove any traces
of fiber.
The positioning of logs is critical to safe and clean operation of this
fireplace. Sooting and other problems may result if the logs are not
properly and firmly positioned in the fireplace. Refer to Figure 18 and
Figure 19 and corresponding WARNING when completing following
log placement steps.

they are centered left to right on the front log support ledge. The flat
bottoms will rest on top of the front log support ledge, and they must
be position all the way forward and touching the back of the grate
tangs. Important: The front right log has a small knot as shown in
Figure 18.
8. Next install the large rear log. It will be centered left to right and
placed all the way to the back of the firebox, on top of the rear log
support. Note: DV25IN models incorporate two small tabs in the
rear log support that keep the back log positioned correctly. DV33IN
models have one small tab in the rear log support to ensure the back
log is in the correct position. The DV35IN models will have two
tabs bent forward in the rear log support to ensure proper left to right
positioning of the log, plus one small tab near the center that keeps
the back log from shifting forward.
9. Locate the center left log. It will have two locator pin holes on the
bottom flat surface. Align the two holes with the two left pins on
the burner assembly. Make sure this log is not raised up off of the
burner. The flat bottom surface must be completely resting flat on
the top of the burner surface.
10. Install the center right log. It will also have two locator pin holes on
the bottom flat surface. Align these two holes with the two right pins
on the burner assembly. Make sure this log is not raised up off of
the burner. The flat bottom surface must be completely resting flat
on the top of the burner surface.
11. Add the right twig by placing the locator pin hole on the bottom of
the twig with the pin on top of the center right log. The tip of the
right twig will rest on top of the rear log near the right end.
12. Add the left twig by placing the locator pin hole on the bottom of
the twig with the pin on top of the center left log. The long branch
of the left twig will rest in a small groove on top of the rear log. This
groove is near the left end of the rear log.

OPERATING INSTRUCTIONS
Initial Lighting
Upon completing the gas line or turning the gas valve on after it
has been in the “OFF” position, a small amount of air will be in the
lines. When first lighting the fireplace, it will take a few minutes
for the lines to purge themselves of this air. Once the purging is
complete, the fireplace will light and operate satisfactorily.
Subsequent lightings of the appliance will not require such purging
if the gas valve is not turned to “OFF.”
Pilot Flame (Figure 21)
The thermopile/thermocouple (standing pilot) tips should be
covered with flame.
Figure 21
750 Millivolt System
The standing pilot (750 millivolt system) is a continuous burning
pilot. The pilot remains ON even when the main burner is OFF.
When you ignite the pilot, the thermopile produces millivolts
(electrical current) which energizes the magnet in the gas valve.
After 30 seconds to 1 minute time period you can release the gas
control knob and the pilot will stay ON. Allow your pilot flame to
operate an additional one (1) to two (2) minutes before you turn the
gas control knob from the PILOT position to the ON position. This
time period allows the millivolts (electrical current) to build-up to
a sufficient level allowing the gas control to operate properly.
1. Follow the SAFETY and LIGHTING INSTRUCTIONS for
standing pilot controls found in this manual and on labels found
in control compartment behind the door assembly.
CAUTION: During the initial purging and subsequent lightings,
never allow the gas valve control knob to remain depressed in
the “pilot” position without pushing the piezo ignitor button
at least once every second.
2. During the operating season, leave the control valve knob in the
“ON” position. This will allow the pilot flame to remain lit. Turn
the burner flame on or off with the fireplace REMOTE/OFF/ON
switch, wall switch or remote controls.
NOTE: The gas control valve allows you to increase or decrease the
height of the main burner flame. The control valve has a pressure
regulator with a knob as shown in Figure 20. Rotate the knob
clockwise to “HI” to increase the flame height and counterclockwise
to “LO” to decrease the flame height.
3. When the operating season is over, turn the REMOTE/OFF/ON
switch to “OFF” and the control valve to “OFF”. The system,
including the pilot light, will be shut down.
Figure 20
The OWNER should carefully read and follow these operating
instructions at all times. Lower the door assembly to view the gas
controls for the fireplace.
