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 lter 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.

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.
•  Your local LP-Gas
Dealer can give you a “Scratch and Sniff” pamphlet. Use it to
nd 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 qualied, do not light pilot lights, perform service,
or make adjustments to appliances on the LP-Gas system. If
you are qualied, 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 lled and allowed to set too
long before relling. 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 orices. 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 con-
tainer is under vapor pressure by turning it off at the container
before it goes completely empty or having it relled 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 reghters
declare them to be safe.
• Use your neighbor’s phone and call a trained LP-Gas service
person and the re 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 reghters 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!

United States) it may be necessary to decrease the input rating by
changing the existing burner orice to a smaller size. Generally,
input should be reduced 4 percent for each 1000 feet above sea
level. However, if the heating value of the gas has been reduced,
this general rule may not apply. Check with local gas utility for proper
orice size identication.
Canadian High Altitude
Altitude: 0-4500 feet (0-1370 m)
When installing this unit at an elevation above 4500 feet (in Canada),
check with local authorities.
Consult your local gas utility for assistance in determining the proper
orice for location.

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 adequate,
contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liqueed 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.

NOTICE: 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 ex connector use only approved ttings.
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 replace 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).

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 rst, followed by
the chimney liner and electrical supply requirements.
2. Minimum replace opening requirements are shown in
Figure 2 of this installation manual. The rebrick (refractory),
glass doors, screen rails, screen mesh and log grates can be
removed from a factory built replace in order to gain mini-
mum gas insert opening requirements prior to installing the
gas replace insert.
3. This insert requires no hearth extensions. Combustible ma-
terial on the oor may be installed up to the insert. Do not
obstruct the lower louver of the insert. The original replace
cannot be returned to solid fuel in this condition.
4. The metal oor of the solid fuel rebox may be removed to
facilitate the installation of the insert. CLEARANCE TO COM-
BUSTIBLE 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 COM-
BUSTIBLE MATERIAL. The side walls and top structure of the
rebox may not be altered with the exception of removable
bafes and dampers. Smoke shields, shelves and bafes may
be removed if attached with mechanical fasteners. The origi-
nal replace cannot be returned to solid fuel in this condition.
5. The original specied clearances of a factory-built re-
place must be maintained, with the exception of the hearth.
Clearances on a masonry replace must be maintained
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 in-
sert and may cover existing air circulation vents or grills on the
solid fuel replace it is installed into. If the surround does not
cover the entire ventilation grill surface, the exposed grill area
should be left open.
NOTICE: Surround panel kits have been tested and approved
to cover existing air circulation vents or grills.

these instructions and the Vent Kit Instructions to ensure that a
proper vent installation is completed. Consult your local Building
Codes before beginning the Installation.
WARNING
THIS GAS INSERT AND VENT ASSEMBLY MUST BE
VENTED DIRECTLY TO THE OUTSIDE AND MUST NEVER BE
ATTACHED TO A CHIMNEY SERVING A SEPARATE SOLID
FUEL BURNING APPLIANCE. EACH GAS APPLIANCE
MUST USE A SEPARATE VENT SYSTEM. COMMON VENT
SYSTEMS ARE PROHIBITED.

26996-7-0411 Page 11
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 identication. 3-inch diameter listed exible 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.

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 identied 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.
NOTICE: The minimum vertical vent rise is 10 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.
NOTICE: The damper of the masonry chimney may need to be
removed to allow installation of the exible-vent pipe.
When installing into a zero clearance, factory built wood-burning
replace, 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 exible vent pipes down through the chimney.
Attach the pipe-to-cap adaptor to the termination cap and the
top of the exible 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 ex pipes to the starting collars with the
adjustable band clamps provided. Slide the gas insert into place,
and position any excess ex vent pipe back up into the chimney.
Begin installation of the insert into the replace opening. Align the
vent slide plate assembly with the guides located on top of the
insert. Work the insert inch by inch into the replace 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 ange, 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.
NOTICE: The front anges of the insert (without surround panels)
should be set at approximately 1”(inch) in front of the face of the
replace.
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.
Note: If desired, it is acceptable to attach metal strapping or
brackets (not provided) from the replace cavity to the insert
outer jacket to secure the Firepace Insert to the replace
hearth or opening.
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-

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 exvent) 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 rst 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 ashlight 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 ex venting and subsequently dripping
out at joints or seams. Condensate can cause corrosion of caps,
pipe and ttings. 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 ttings 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


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.

BLOWER ACCESSORY
Operation
The replace insert is equipped with a factory installed blower that
includes a fan control switch, plus a rheostat (speed control).
The speed control knob is located behind the lower louver at the
right side of the insert.
From a cold start, the temperature activated fan control switch will
normally take 5-10 minutes to heat up and energize the blower.
Once the blower is energized, adjust the blower speed control as
desired, then replace the lower louver.
When the insert is shut off, it may take 30-40 minutes for the
heated unit to dissipate (cool down) enough for the blower to shut
off automatically. NOTICE: The blower shut off times will vary on
blower speed and BTU input level setting control by adjustment of
the HI/LO knob located on the gas valve.
Blower removal instructions
Servicing or removal of the blower system must be performed by

OPERATING INSTRUCTIONS
instructions at all times. Lower the door assembly to view the gas
controls for the replace.
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 rst lighting the replace, it will take a few minutes for the
lines to purge themselves of this air. Once the purging is complete,
the replace 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 ame.
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 ame 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 sufcient
level allowing the gas control to operate properly.
1. Follow the SAFETYand LIGHTING INSTRUCTIONS for standing
pilot controls found in this manual and on labels found in control
compartment behind the door assembly.
WARNING
During the initial purging and subsequent lightings, never
allow the gas valve control knob to remain depressed in the

2. During the operating season, leave the control valve knob in the
“ON” position. This will allow the pilot ame to remain lit. Turn
the burner ame on or off with the replace REMOTE/OFF/ON
switch, wall switch or remote controls.
NOTICE:The gas control valve allows you to increase or decrease
the height of the main burner ame. The control valve has a pressure
regulator with a knob as shown in Figure 20. Rotate the knob
clockwise to “HI” to increase the ame height and counterclockwise
to “LO” to decrease the ame 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.
