IMPORTANT SAFETY INFORMATION

23552-4-0408Page 4
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!
SAFETY INFORMATION FOR USERS OF LP GAS
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
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.
• 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 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.
• 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.

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.
On direct ignition valves, hex plugs may be replaced with hose fittings
for pressure checks, then reinstalled before operating fireplace.
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 (3.5 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 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. (.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).

Note: Never use plastic pipe. Check to confirm whether your
local codes allow copper tubing or galvanized.
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.

REAR VENT CONVERSION
Converting flue take-off to rear venting
When switching out the flue and inlet vent collars to run horizontally
off the rear vent, the following steps must be taken.
1. Remove the inlet vent collar (8 screws) and flue collar (4 screws)
from the top of the fireplace, and set to the side.
2. Remove the inlet cover plate and flue cover plate located on the
back of the fireplace. These will be used to close the top flue
and inlet openings.
3. Insert the insulation retainer bracket and insulation into the top
flue pipe before reinstalling the flue cover plate over the top flue
with 4 screws.
4. Reinstall the inlet cover plate over the top inlet opening with 4
screws. See illustration above..
5. Install the flue collar assembly to the rear flue with 4 screws.
6. Install the inlet vent collar to the rear of the fireplace with 8
screws.
7. This completes the conversion for a rear vent application.
Note: for top vented installations, the insulation and retainer are
to be removed from the flue pipe and discarded.

Attention: Add 3-3/4" to “A” dimensions when using a flush
mantel base.
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 flooring, it shall be installed on a metal or wood
panel extending the full width and depth of the appliance. The
vertical dimension in Figure 12 must be adjusted when a metal or
wood panel is placed beneath the appliance.
Finishing (Figures 13 and 14)
Finish the walls with the material of your choice. Figure 3 on
page 9 shows the minimum vertical and corresponding maximum
horizontal dimensions of mantels or other combustible projections
above the top front edge of the fireplace.
Only non-combustible materials may be used to cover the black
fireplace front.
Caution: If the joints between the finished wall and the fireplace
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 fireplace surround.
Flush Mount Mantel Installation (Figure 11)
The fireplace must extend 3/4" beyond finished wall surface when
using a flush mount mantel. Refer to Figure 11 to locate nailing
flanges on fireplace sides. Mark and drill two (2) 1/8" holes into
fireplace side to mount each nailing flange. Use eight (8) 1/2"
hex-head screws supplied in hardware package to attach nailing
flanges to fireplace sides.
Figure 11
Attention: When fireplace is installed in optional full cabinet mantel
or corner mantel the (4) four nailing flanges shown in Figure 11 will
not be installed on the side of outer casing. The fireplace will be
attached to the full cabinet mantel or corner mantel with the (2) two
nailing flanges located on the top of the outer casing assembly.
Framing (Figure 12)
Fireplace framing can be built before or after the fireplace is set in
place. Framing should be positioned to accommodate wall covering
and fireplace facing material. The fireplace framing should be
constructed of 2 x 4 lumber or heavier. The framing headers may
rest on the fireplace standoffs. Refer to Figure 12 for minimum
framing dimensions.

To Use the Vent Graph (Figure 20)
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 floor of the unit is 35
feet, the horizontal run to the outer wall flange must not
exceed 6.5 feet.
EXAMPLE B:
If the vertical dimension from the floor of the unit is 6.5
feet, the horizontal run to the outer wall flange 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 (2). These elbows can be installed
in either the vertical or horizontal run.
Note: On vertical venting the first elbow does not get
counted.
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" (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.

Positioning the Fireplace
Determine the exact position of the appliance so the direct vent
termination will be centered (if possible) between two (2) studs. This
will avoid any extra framing. All vent kit pipes should be assembled
on the unit after the unit is moved into the final position.
Cutting the Hole (Figures 24)
After the fireplace has been positioned in its permanent location,
the hole through the exterior wall of the house can be cut. This hole
must be 10" (254mm) 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)
