This fireplace is a vented product. This fireplace must be
properly installed by a qualified service person. The glass
door must be properly seated and sealed. If this unit is not
properly installed by a qualified service person with glass
door properly seated and sealed, combustion leakage can
occur.
Early signs of carbon
monoxide poisoning are similar to the flu with headaches,
dizziness and/or nausea. If you have these signs, the fire-
place may not have been installed properly. Get fresh air
at once! Have the fireplace inspected and serviced by a
qualified service person. Some people are more affected
by carbon monoxide than others. These include pregnant
women, people with heart or lung disease or anemia,
those under the influence of alcohol, and those at high
altitudes.
Propane/LP gas and natural gas are both odorless. An
odor-making agent is added to each of these gases. The
odor helps you detect a gas leak. However, the odor added
to these gases can fade. Gas may be present even though
no odor exists.
Make certain you read and understand all warnings. Keep
this manual for reference. It is your guide to safe and proper
operation of this fireplace.
1. This appliance is only for use with the type of gas
indicated on the rating plate. This appliance is not
convertible for use with other gases unless a certified
kit is used.
2. For propane/LP fireplace, do not place propane/LP
supply tank(s) inside any structure. Locate propane/
LP supply tank(s) outdoors. To prevent performance
problems, do not use propane/LP fuel tank of less than
100 gal. capacity.
3. If you smell gas
• shut off gas supply.
• do not try to light any appliance.
• do not touch any electrical switch; do not use any
phone in your building .
• immediately call your gas supplier from a neighbor’s
phone. Follow the gas supplier’s instructions.

It is normal for fireplaces fabricated of steel to give off
some expansion and/or contraction noises during the
start up or cool down cycle. Similar noises are found
with your furnace heat exchanger or car engine.
It is not unusual for gas fireplaces to give off some
odor the first time it is burned. This is due to the
manufacturing process.
It is recommended that you burn your fireplace for at
least ten (10) hours the first time you use it. Place the
fan switch in the “OFF” position during this time.

There are two basic types of direct-vent installation:
• Horizontal Termination
• Vertical Termination
It is important to select the proper length of vent pipe for
the type of termination you choose. It is also important
to note the wall thickness.
Select the amount of vertical rise desired. All horizontal run of venting must have 1/4" rise for every 12"
of run towards the termination.
You may use up to three 90° elbows in this vent configuration. Refer to Horizontal Termination Configu-
rations on Pages 22 and 23.
Measure the distance from the fireplace floor to the ceiling. Add the ceiling thickness, the vertical rise in
an attic or second story, and allow for sufficient vent height above the roof line.
You may use two 45° elbows in place of a 90° elbow. You must follow rise to run ratios when
using 45° elbows. The appliance is approved for use with three 90° elbows maximum or a combination
of 90° and 45° elbows up to a maximum of 270°.
For two-story applications, firestops are required at each floor level. If an offset is needed in the attic,
additional pipe and elbows will be required.
You may use a chase with a vent termination with exposed pipe on the exterior of the house. Refer to
Installing Vent System in a Chase below. If pipe is enclosed in chase, it is not exposed.
It is very important that the venting system maintain its balance between the combustion air intake and
the flue gas exhaust. Certain limitations apply to vent configurations and must be strictly followed.
A chase is a vertical boxlike structure built to enclose venting that runs along the outside of a building.
A chase is required for such venting.

The Vent Graph should be read in conjunction with the following
vent installation instructions to determine the relationship between
the vertical and horizontal dimensions of the vent system.
1. Determine the height of the center of the horizontal vent pipe exit-
ing through the outer wall. Using this dimension on the Sidewall
Vent Graph below, locate the point intersecting 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 fireplace in
accordance with same.
If the vertical dimension from the floor of the fireplace
is 11' (3.4 m) the horizontal run to the face of the outer wall must
not exceed 14' (4.3 m).

When installed as a rear vent unit this appliance may be vented directly to a termination located on
the rear wall behind the appliance
• The maximum horizontal distance between the rear of the appliance and the outside face of the
rear wall is 20" (508 m). Figure 15
• Only one 45° elbow is allowed in these installations.
1. Locate and cut the vent opening in the wall. For
combustible walls first frame in opening.
Cut a 11Z\x"H x 9Z\x" W (292 x
241 mm) hole through the exterior wall and frame as
shown. Figure 16
Hole opening should be 7Z\x"
(190 mm) in diameter.
2. Rigid vent pipes and fittings have special twist-lock
connections. Assemble the desired combination of
pipe and elbows to the appliance adaptor with pipe
seams oriented towards the wall or floor.
Twist-lock Procedure: The female ends of the pipes
and fittings have three locking lugs (indentations).
These lugs will slide straight into matching slots on
the male end of adjacent pipes and fittings. Push the
pipe sections together and twist one section clockwise
approximately one-quarter turn until the sections are
fully locked. Figure 17
3. Attach vent pipe assembly to the fireplace. Set fire-
place in front of its permanent location to insure mini-
mum clearances. Mark the wall for a 11Z\x"H x 9Z\x"W
(292 x 241 mm) rectangle hole (for noncombustible
material such as masonry block or concrete, a 7Z\x"
[190 mm] diameter hole is acceptable). Figure 16.
The center of the hole should line up with the center
line of the horizontal rigid vent pipe end. Be sure to
allow for minimum rise. Cut a 11Z\x"x9Z\x" rectangle hole
through combustible exterior wall (7Z\x" diameter hole
if noncombustible). Frame as necessary. Allow 1/4"
minimum rise per foot. Figure 16
