IMPORTANT SAFETY INFORMATION


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 Propane 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 Propane 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.
Propane 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. Imme-
diately go into action as instructed earlier.
-
sions. 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 Propane Gas. Your local Propane
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 Propane Gas has a weak or abnormal odor, call your
Propane Gas Dealer.
• If you are not qualied, do not light pilot lights, perform service,
or make adjustments to appliances on the Propane Gas system.
If you are qualied, consciously think about the odor of Propane
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 Propane 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 Propane 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 Propane Gas Dealer. A peri-
odic sniff test of the Propane Gas is a good safety measure
under any condition.
• If, at any time, you do not smell the Propane 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 Propane 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.
• Propane 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 Propane 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 Propane 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
PROPANE GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the Propane Gas.
That’s your signal to go into immediate action!

Installing a New Main Gas Shut-Off
Each appliance should have its own manual gas shut-off.
A manual main gas shut-off 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.

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).

The replace must extend 3/4" beyond nished wall surface when
using a ush mount mantel. Refer to Figure 13 to locate nailing
anges on replace sides. Mark and drill two 1/8" holes into replace
side to mount each nailing ange. Use eight 1/2" hex-head screws
supplied in hardware package to attach nailing anges to replace
sides.

Attention: When replace is installed in optional full cabinet mantel
or corner mantel the four nailing anges shown in Figure 13 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.

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. (If the fan option is used.)
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.
Acceptable vertical and horizontal vent run.
(40' maximum vertical and 20' maximum horizontal)
Unacceptable vertical and horizontal vent run.

Attention: Refer to Figure 20 for additional venting requirements.
Figure 23
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" (178mm) below grade level.
The 7" (178mm) 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" (305mm) high x 10" (254mm) wide with its center line
determined by the amount of vertical rise and horizontal run of the
termination. See Figure 24. When locating the hole it must be noted
that the bottom of the cap must be 12" (305mm) above the ground
level, and top of the cap must be no less than 18" (457mm) below a
combustible projection, and no closer than 9" (229mm) to any wall
running parallel to vent termination. See Figure 25.
