Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must nd 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 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.
Propane (LP-Gas) is a ammable gas which can cause res
and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precautions
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 reading 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
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 un-
der 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 container 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!

Installing a New 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.
Never use an exposed ame 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 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).
CAUTION! 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).

INSTALLATION
Framing and Finishing
1. Choose unit location.
2. Frame in replace with a header across the top. It is important
to allow for nished face when setting the depth of the frame.
See Figure 11.
3. Attach replace to frame using adjustable nailing ange. Preset
depth to suit facing material (adjustable to 3/8”, 1/2” or 3/4” depths).
NOTICE: Fireplace must mount ush to facing material. If facing
material requires more depth than 3/4”, mark and drill two 1/8”
holes into replace side at appropriate depth. See Figure 10.
4. Use eight 1/2” hex-head screws supplied in hardware package,
to screw through slotted holes in nailing ange and then screw
into pre-drilled holes on replace side. Measure from face of
replace to face of nailing ange to determine nal depth.
Vent Pipe Clearance
Notice: Maintain one inch of clearance around vertical vent pipe.
See Figure 12.

INSTALLATION (continued)
Figure 13
Attention: When replace is installed in optional full cabinet mantel
or corner mantel the four nailing anges shown in Figure 10 will
not be installed on the side of outer casing. The replace will be
attached to the full cabinet mantel or corner mantel with the two
nailing anges located on the top of the outer casing assembly.
Framing
Fireplace framing can be built before or after the replace is set in
place. Framing should be positioned to accommodate wall covering
and replace facing material. The replace framing should be
constructed of 2 x 4 lumber or heavier. The framing headers may
rest on the replace standoffs. Refer to Figure 14 for minimum
framing dimensions.
CAUTION: MEASURE FIREPLACE DIMENSIONS AND
VERIFY FRAMING METHODS,AND WALL COVERING DETAILS
BEFORE FRAMING CONSTRUCTION BEGINS.
Framing dimension “A” includes a six inch clearance
for standoffs on replace. After installing replace into
framing, the nished non-combustible wall surface must
cover the six inch opening above the replace.
Attention: Appliance must not be recessed below any ooring,
including carpeting, for proper front mounting. A metal or wood panel
extending the full width and depth of the appliance may be required
to raise the unit to the same level, or above existing ooring. The
vertical dimension in Figure 14 must be adjusted when a panel is
placed beneath the appliance.

WARNING: If a base is not used and the appliance is installed
directly on tile or other combustible material other than wood ooring,
it shall be installed on a metal or wood panel extending the full width
and depth of the appliance. The vertical dimension in Figure 14
must be adjusted when a metal or wood panel is placed beneath
the appliance.
Finishing
Finish the walls with the material of your choice. Figure 5 on page 10
shows the minimum vertical and corresponding maximum horizontal
dimensions of mantels or other combustible projections above the
top front edge of the replace.
The black replace front must not be covered. It must be ush
to the nished wall.
WARNING: When nishing the replace never obstruct or
modify the air inlet/outlet louvers in any manner. Provide
adequate clearances around air openings into the combustion
chamber.
CAUTION: If the joints between the nished wall and the re-
place surround (top and sides) are sealed, a 300°F minimum seal-
ant material must be used. These joints are not required to be
sealed. Only non-combustible material (using 300°F minimum
adhesive if needed), can be applied as facing to the replace.

Attention: Cold climate installation recommendation:
When installing this unit against a non-insulated exterior
wall, it is recommended that the outer walls be insulated to
conform to applicable insulation codes.
Vent Runs
In planning the installation for the replace, it is necessary to install
certain components before the appliance is completely positioned
and installed. These include the direct vent system, gas piping for
the appliance and the electrical wiring.
The appliance can be mounted on any of the following surfaces:
1. A at, hard combustible (burnable) surface.
2. A raised wooden platform.
3. Four corner supports. (Example: Four concrete masonry blocks.)
These supports must be positioned so they contact all four
perimeter edges on the bottom of the unit (if allowed by local
codes).

To Use the Vent Graph
1. Determine the height of the center of the horizontal vent
pipe. Using this dimension on the Sidewall Vent Graph,
locate the point it intersects with the slanted graph line.
2. From the point of this intersection, draw a vertical line to
the bottom of the graph.
3. Select the indicated dimension, and position the unit in
accordance with same.
EXAMPLE A:
If the vertical dimension from the oor of the unit is 35 feet,
the horizontal run to the outer wall ange must not exceed
6.5 feet.
EXAMPLE B:
If the vertical dimension from the oor of the unit is 6.5 feet,
the horizontal run to the outer wall ange must not exceed
14.5 feet.
Special Note: For each 45 degree elbow installed in the
horizontal run, the length of the horizontal run MUST be
reduced by 18" (45cm). This does not apply if the 45 degree
elbows are installed on the vertical part of the vent system.
Reduce 3' for every 90° elbow.
Example: According to the chart the maximum horizontal
vent length is 20' and if two 45 degree elbows are required
in the horizontal vent it must be reduced to 17'.
The maximum number of 45 degree elbows permitted per
side wall installation is two. These elbows can be installed
in either the vertical or horizontal run.
Note: On vertical venting the rst elbow does not get counted.
Note: Flue heat shield must be installed for venting applications
with less than two feet of vertical pipe off the top of the replace.
Acceptable vertical and horizontal vent run.
(40' maximum vertical and 20' maximum horizontal)
Unacceptable vertical and horizontal vent run.

Below Grade Installation
When it is not possible to meet the required vent terminal clearances
of 12” (305mm) above grade level, a snorkel kit is recommended.
It allows installation depth down to 7” (178 mm) below grade level.
The 7” (178 mm) is measured from the center of the horizontal vent
pipe as it penetrates through the wall.
Ensure the sidewall venting clearances are observed. If venting
system is installed below ground, we recommend a window
well with adequate and proper drainage to be installed around
the termination area.

Positioning the Fireplace
Determine the exact position of the appliance so the direct vent
termination will be centered (if possible) between two studs. This
will avoid any extra framing. All vent kit pipes should be assembled
on the unit after the unit is moved into the nal position.
Cutting the Hole
After the replace has been positioned in its permanent location,
the hole through the exterior wall of the house can be cut. This hole
must be 12” (305 mm) high x 10” (254 mm) wide with its center line
determined by the amount of vertical rise and horizontal run of the
termination. See Figure 26. When locating the hole it must be noted
that the bottom of the cap must be 12” (305 mm) above the ground
level, and top of the cap must be no less than 18” (457 mm) below
a combustible projection, and no closer than 9” (229 mm) to any
wall running parallel to vent termination. See Figure 27.
