SAFETY INFORMATION FOR USERS OF LP GAS
Propane (LP-Gas) is a ammable gas which can cause
res and explosions. In its natural state, propane is odor-
less 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.
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!
• 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 reghters 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 reghters 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.
NO ODOR DETECTED - ODOR FADE
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.
SOME POINTS TO REMEMBER
• 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 qualied, do not light pilot lights, perform
service, or make adjustments to appliances on the LPGas system. If you are qualied, 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 relling. 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
orices. 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 relled before it is
completely empty.

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
exible appliance connector cannot exceed three feet in length.
Figure 8
Gas Supply Pressure (inches w.c.)
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 liqueed 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.
On direct ignition valves, hex plugs may be replaced with hose ttings
for pressure checks, then reinstalled before operating replace.
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 (3.5 kPa).
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 (3.5 kPa).
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. (.871 kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 4.5” w.c.
(1.120 kPa) for the purpose of input adjustment to a maximum of
14.0” w.c. (3.484 kPa). Propane gas models will have a manifold
pressure approximately 10.0” w.c. (2.49 kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 10.8” w.c.
(2.68 kPa) for the purpose of input adjustment to a maximum of
14.0” w.c. (3.484 kPa).

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.
3. Attach replace to frame using adjustable frame. Preset depth
to suit facing material (adjustable to 1/2”, 5/8” or 3/4” depths).
4. Use eight 1/2” hex-head screws supplied in hardware package,
to screw through slotted holes in drywall strip and then screw
into pre-drilled holes on replace side. See Figure 10. Measure
from face of replace to face of drywall strip to determine nal
depth.
Vent Pipe Clearance
Note: Maintain one inch of clearance around vertical vent pipe. See
Figure 11. For horizontal vent, maintain a minimum 1” clearance to
the bottom and sides of the vent, and 3” clearance to combustibles
above the vent pipe. See Figure 12.

INSTALLATION (continued)
Flush Mount Mantel Installation
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.
Figure 13
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.
CAUTION: MEASURE FIREPLACE DIMENSIONS AND VERIFY
FRAMING METHODS, AND WALL COVERING DETAILS BEFORE
FRAMING CONSTRUCTION BEGINS.
Framing dimension "A" includes a three inch clearance for
standoffs on rebox. After installing rebox into framing,
the nished wall surface must cover the three inch opening
above the rebox.
Note: For nishing to top of replace, refer to Figure 14.

Attention: If a base or mantel is not used and the appliance is
installed directly on carpeting, 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.
Only non-combustible materials may be used to cover the black
replace front.
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 replace
surround (top and sides) are sealed, a 300°F minimum sealant
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 surround.

VENTING FIREPLACE - TOP
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" (457 mm). 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.

Below Grade Installation
When it is not possible to meet the required vent terminal clearances
of 12” (305 mm) 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.
