Please leave these instructions with the appliance.
Please retain these instructions for future reference
.
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 prob-
lems, do not use propane/LP fuel tank of less than 100
lbs. capacity.
3. If you smell gas
• shut off gas supply.

6. Carefully supervise young children when they are in
the room with fireplace.
7. Do not modify fireplace under any circumstances. Any
parts removed for servicing must be replaced prior to
operating fireplace.
8. Turn fireplace off and let cool before servicing, install-
ing, or repairing. Only a qualified service person should
install, service, or repair the fireplace. Have burner
system inspected annually by a qualified service
person.
9. You must keep control compartments, burners, and
circulating air passages clean. More frequent cleaning
may be needed due to excessive lint and dust. Turn off
the gas valve and pilot light before cleaning fireplace.
10. Have venting system inspected annually by a qualified
service person. If needed, have venting system cleaned
or repaired. Refer to Cleaning and Maintenance, Page
49.

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.

The fireplace must be secured to the floor and/or to framing studs as shown in Figure 6. Use two
(2) wood screws or masonry/ concrete screws to secure fireplace to the floor. Use four (4) screws
to attach fireplace to framing. The side nailing flanges are 1/2" or 5/8" to accommodate different
wall thickness.
: Any remote wiring (i.e. remote control, wall switch, and optional fan) must be done prior to
final finishing to avoid costly reconstruction.
Only noncombustible materials (i.e. brick, tile, slate, steel, or other materials with a UL fire rating
of Zero) may be used to cover the black painted face of the appliance. It is permissible to bring
combustible wall board to the top of the stand offs on the top and the sides of the unit. A 300°F
minimum adhesive may be used to attach facing materials to the black surface. If joints between
the finished wall and the fireplace surround are sealed, a 300°F minimum sealant material (General

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 below 7Z\x" of vertical rise from floor of fireplace. With 7Z\x feet or more of vertical rise
form the floor of the fireplace, the horizontal run may be level. NEVER run vent piping down.
You may use up to three 90° elbows in this vent configuration. Refer to Vertical/Horizontal Termination Con-
figurations on Page 16.
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. See Installing A
Vent System in an Outside 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 dimen-
sions of the vent system.
1. Determine the height of the center of the horizontal
vent pipe exiting 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 fire-
place in accordance with same.
Example: 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 16' (4.9 m).

Locate vent opening on the wall. It may be necessary to
first position the fireplace and measure to obtain hole lo-
cation. Depending on whether the wall is combustible or
noncombustible, cut opening to size. Figure 11 (For com-
bustible walls first frame in opening.)
Cut a 10Z\x”H x 10Z\x”W (267 x 267
mm) hole through the exterior wall and frame as shown.

The Vent Graph, showing the relationship between vertical
and horizontal side wall venting, will help to determine the
various dimensions allowable. Figure 10

When vent exits through foundations less than 20" below
outcrop, the termination must be flush up with outcropped
wall above.
It is best to locate the fireplace in such a way that minimizes
the number of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent
pipe from the flue collar of the fireplace (or the top of the
Transition Elbow) to the face of the finished outside wall.
• The maximum number of 90° elbows per side wall
installation is three (3). Figure 14

• A minimum of 24" is required before a 90° elbow. If a 90°
elbow is fitted directly after 24" vertical section mounted
to the top of the fireplace, the maximum horizontal vent
run before the termination or a vertical rise is 36” (914
mm). Figure 15
• If a 90° elbow is used in the horizontal vent run (level
height maintained) the horizontal vent length is reduced
by 36". Figures 14 and 15. This does not apply if the
90° elbows are used to increase or redirect a vertical
rise. Figure 16
According to the vent graph (Page 16) the maxi-
mum horizontal vent length in a system with a 10' vertical
rise is 20’ (6 m) and if a 90° elbow is required in the hori-
zontal vent it must be reduced to 17' (5.2 m).
In Figures 16 and 17 dimension A plus B must not be
greater than 17' (5.2 m).

• The maximum number of 45° elbows permitted per side
wall installation is two (2). These elbows can be installed
in either the vertical or horizontal run.
• For each 45° elbow installed in the horizontal run, the
length of the horizontal run MUST be reduced by 18" (45
cm). This does not apply if the 45° elbows are installed
on the vertical part of the vent system.
• The maximum number of elbow degrees in a system is
270°. Figure 18
When it is not possible to meet the required vent terminal
clearances of 12" above grade level, a snorkel kit is recom-
mended. 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.
If installing a snorkel, a minimum 24" vertical rise is neces-
sary. The maximum horizontal run with the 24” vertical pipe
is 36". This measurement is taken from the collar of the
fireplace (or transition elbow) to the face of the exterior wall.
See the Sidewall Venting Graph for extended horizontal
run if the vertical exceeds 24".
1. Establish vent hole through the wall.
2. Remove soil to a depth of approximately 16" below base
of snorkel. Install drain pipe. Install window well (not
supplied). Refill hole with 12" of coarse gravel leaving
a clearance of approximately 4" below snorkel. Figure
19
3. Install vent system.
4. Ensure a watertight seal is made around the vent pipe
coming through the wall.
5. Apply high temperature sealant caulking (supplied)
around the 5" and 8" snorkel collars.
6. Slide the snorkel into the vent pipes and secure to the
wall.
7. Level the soil so as to maintain a 4" clearance below
snorkel. Figure 19

Vertical sections of this vent system require a minimum of
1" clearance to combustibles on all sides of the pipe.
• Up to two 45° elbows may be used within the horizontal
run. For each 45° elbow used on the horizontal plane,
the maximum horizontal length must be reduced by 18"
(450 mm).
Maximum horizontal length
No elbows = 10’ (3 m)
1x45° elbows = 8.5’ (2.6 m)
2x45° elbows = 7’ (2.1 m)
• A minimum of an 8' (2.5 m) vertical rise is required.
• Two sets of 45°elbows offsets may be used within the
vertical sections. From 0 to a maximum of 8' (2.5 m)
of vent pipe can be used between elbows. Figure 23
• The maximum angular variation allowed in the system
is 270°. Figure 23

This gas fireplace has been approved for,
• Vertical installations up to 40' (12 m) in height. Up to
a 10' (3 m) horizontal vent run can be installed within
the vent system using a maximum of two 90° elbows.
Figure 22
Horizontal sections of this vent system require a
minimum of 3" clearances to combustibles at the top of
the flue and 1" clearance at the sides and bottom until the
flue penetrates the outside wall. A minimum 1" clearance
all around the flue is acceptable at this point of penetration.
Unless the vertical run is 7Z\x feet or higher form floor of
fireplace, the clearance for the horizontal run is 1" on all
sides.

1. Determine the route your vertical venting will take. If
ceiling joist, roof rafters or other framing will obstruct
the venting system, consider an offset. Refer to Figure
24 to avoid cutting load bearing members.
For optimal flame appearance, a restrictor disk is necessary
on straight vertical runs of 10' of more.
• Runs may not incorporate elbows.
• The disk is part number 56D3027 and is included in
installation manual packet.
• Drop the disk into a 5" inner collar before installing
the first section of flue or install at the last section
before installing the termination.
• An additional disk may be installed on runs of 35' or more.
Rotate disks perpendicular to each other.
Pay special attention to these installation instructions
for required clearances (air space) to combustibles when
passing through ceilings, walls, roofs, enclosures, attic
rafters, etc. Do not pack air spaces with insulation. Also
note maximum vertical rise of the venting system and any
maximum horizontal offset limitations. Offsets must fall
within the parameters shown in Figures 23 and 24.
2. Set fireplace in desired location. Drop a line plumb down
from the ceiling to the position of the flue exit. Mark the
center point where the vent will penetrate the ceiling.
Drill a small locating hole a this point.
Drop a plumb line from the inside of the roof to the ceiling
locating hole in the ceiling. Mark the center point where
the vent will penetrate the roof. Drill a small locating hole
at this point.
1. Cut a 101/2" (241 mm) square hole in the ceiling using
the locating hole as a center point The opening should
be framed to 101/2"x101/2" (241 x 241 mm) inside dimen-
sions as shown in Figure 26 using framing lumber the
same size as the ceiling joist. If the area above the ceil-
ing is an insulated ceiling or a room, nail firestop from
the top side. This prevents loose insulation from falling
into the required clearance space. Figure 25. Otherwise,
install firestop below the framed hole. Figure 26

2. Assemble the desired lengths of pipe and elbows nec-
essary to reach from the burner system flue up through
the firestop. Be sure pipe and elbow connections are
fully twist-locked.
3. Cut a hole in the roof using the locating hole as a center
point. (Cover any exposed open vent pipes before
cutting hole in roof). The 101/2"x101/2" (267 x 267 mm)
hole must be measured on the horizontal. Actual length
may be larger depending on the pitch of the roof. There
must be a 1" minimum clearance from the vent pipe to
combustible materials. (Insulation should be considered
a combustible material).
4. Connect a section of pipe and extend up through the
hole.
If an offset is needed to avoid obstructions, you
must support the vent pipe every three (3) feet. Use wall
straps for this purpose. Refer to Page 18, Figure 22.
Whenever possible, use 45° elbows instead of 90° elbows.
The 45° elbow offers less restriction to the flow of the flue
gases and intake air.
5. Place the flashing over the pipe section(s) extending
through the roof. Secure the base of the flashing to
the roof and framing with roofing nails. Be sure roofing
material overlaps the top edge of the flashing. There
must be a 1" clearance from the vent pipe to combustible
materials.
6. Continue to add pipe sections until the height of the vent
cap meets the minimum building code requirements.
You must increase vent height for steep roof
pitches. Nearby trees, adjoining roof lines, steep pitched
roofs, and other similar factors may cause poor draft or
down-drafting in high winds. Increasing the vent height
may solve this problem.
If the vent pipe passes through any occupied areas
above the first floor, including storage spaces and closets,
you must enclose pipe. You may frame and sheetrock the
enclosure with standard construction material. Make sure
to meet the minimum allowable clearances to combustibles.
Do not fill any of the required clearance spaces with
insulation.
