INSTALLATION PLANNING
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.
FOR HORIZONTAL TERMINATION
Select the amount of vertical rise desired. All horizontal run
of venting must have
termination.
You may use up to three 90° elbows in this vent configuration.
See Vertical/Horizontal Termination Configurations on pages
17 and 18.
FOR VERTICAL TERMINATION
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.
NOTE: You may use two 45° elbows in place of a 90° elbow . Y ou 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.

Never run the vent pipe level or
downward. This may cause excessive
temperatures which could cause
a fi re.
WARNING
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.
Treatment of fi restops and construction of the chase may vary from building type to
building type. These instructions are not substitutes for the requirements of local
building codes. You must follow all local building codes.
NOTICE
When installing in a chase, you should insulate the chase as you would the outside walls of
your home. This is especially important in cold climates. Insulation should be considered
a combustible material. Maintain proper clearances to all combustible materials.

HOW TO USE THE VENT GRAPH
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
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 fireplace in
accordance with same.
Example: If the vertical dimension from the fl oor of the
fi replace is 11' (3.4m) the horizontal run to the face of the
outer wall must not exceed 14' (4.3m).
Example: If the vertical dimension from the fl oor of the unit
is 7’ (2.14m), the horizontal run to the face of the outer
wall must not exceed 8

CONFIGURATIONS
Since it is very important that the venting system maintain its balance between the combustion air intake and the flue
gas exhaust, certain limitations as to vent configurations apply and must be strictly adhered to.
The Vent Graph, showing the relationship between vertical and horizontal side wall venting, will help to determine the various dimensions allowable. See Figure 10.
NOTE: Horizontal sections of this vent system require a minimum of 3" clearances to combustibles at the top of the
fl ue and 1" clearance at the sides and bottom until the fl ue penetrates the outside wall. A minimum 1" clearance all
around the fl ue is acceptable at this point of penetration.
Vertical sections of this vent system require a minimum of 1" clearance to combustibles on all sides of the pipe.
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). See Figure 11.
• 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). See
• If a 90° elbow is used in the horizontal vent run (level height
maintained) the horizontal vent length is reduced by 36".
See Figures 11 and 12, page 17. This does not apply if the
90° elbows are used to increase or redirect a vertical rise.
See Figure 14.
Example: According to the vent graph (page 16) the
maximum horizontal vent length in a system with a 10'
vertical rise is 20’ (6m) and if a 90° elbow is required in
the horizontal vent it must be reduced to 17' (5.2 m).
In Figures 13 and 14 dimension A plus B must not be greater
than 17' (5.2m).
• 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" (45cm). 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°.
When it is not possible to meet the required vent terminal clearances of 12" 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 that 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.
If installing a snorkel, a minimum 24" vertical rise is necessary. 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. See Figure 16.
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. See Figure 16.
• Do not back fi ll around snorkel.
• A clearance of at least 4" must be maintained between the
snorkel and the soil.
WARNING
If the foundation is recessed, use recess brackets (not supplied) for securing lower portion of the snorkel. Fasten brackets to
wall first, then secure to snorkel with self drilling #8x1/2 sheet metal screws. It will be necessary to extend vent pipes out as
far as the protruding wall face. See Figure 17.

VENT INSTALLATION
VERTICAL (THROUGH-THE-ROOF)
APPLICATIONS
This gas fireplace has been approved for,
• Vertical installations up to 40' (12m) in height. Up to a 10'
(3m) horizontal vent run can be installed within the vent
system using a maximum of two 90° elbows. See Figure
18.
NOTE: Horizontal sections of this vent system require
a minimum of 3" clearances to combustibles at the top
of the fl ue and 1" clearance at the sides and bottom
until the fl ue penetrates the outside wall. A minimum
1" clearance all around the fl ue is acceptable at this
point of penetration.
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"
(450mm).
• A minimum of an 8' (2.5m) 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. See Figure 19.
• The maximum angular variation allowed in the system is
270°. See Figure 19.
• The minimum height of the vent above the highest point
of penetration through the roof is 2' (610mm).
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. See Figure 20 to avoid cutting load bearing
members.
VENT INSTALLATION
Roof
Flashing
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.
NOTE: 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 19 and 20.
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.

1. Cut a 10
/2" (241mm) square hole in the ceiling using the locating hole as a center point The opening should be framed to
101/2"x101/2" (241mm x 241mm) inside dimensions as shown
in Figure 22 using framing lumber the same size as the ceiling
joist. If the area above the ceiling is an insulated ceiling or a
room, nail firestop from the top side. This prevents loose insulation from falling into the required clearance space. See Figure
21. Otherwise, install firestop below the framed hole. See Figure
22.
2. Assemble the desired lengths of pipe and elbows necessary 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
1/
in roof). The 101/2"x10
2
" (241mm x 241mm) 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.
NOTE: If an offset is needed to avoid obstructions, you must support the vent pipe every three (3) feet.
Use wall straps for this purpose. See Figure 18, page 19. Whenever possible, use 45° elbows instead of
90° elbows. The 45° elbow offers less restriction to the fl ow of the fl ue 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.
NOTE: 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.
NOTE: If the vent pipe passes through any occupied areas above the fi rst fl oor, 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 fi ll any of the
required clearance spaces with insulation.

CLEANING AND MAINTENANCE
Turn off gas before servicing fi replace. It is recommended that a qualifi ed service
technician perform these check-ups at the beginning of each heating season
WARNING
BURNER, PILOT AND CONTROL COMPARTMENT
Keep the control compartment, logs, and burner areas surrounding the logs clean by vacuuming or brushing at least twice a
year. Make sure the burner porting, pilot air opening and burner air opening are free of obstructions at all times.
Thermocouple
PILOT FLAME
The flames from the pilot should be visually checked as soon as the heater is
installed and periodically during normal operation. The pilot flame must always be present when the fireplace is in operation. See Figure 40. The pilot flame
has three distinct flames, one engulfing the thermopile, one engulfing the thermocouple, and the other reaching to the main burner.
Thermopile
BURNER
Inspect area around the injector. Remove any lint or foreign material with a
brush or vacuum.
BURNER FLAME
The flames from the burner should be visually checked
as soon as the heater is installed and periodically during
normal operation. In normal operation, at full rate, and
after operating for about 15 to 30 minutes, the flame
should be yellow and slightly taller than the rear log.
See Figure 41.
If the flame is blue and only in the center, turn off unit
and let cool. After unit is cool, remove logs and check to
make sure the back holes in the burner are not covered
with rock wool. If the back holes are clear, add more rock
wool to the center of the burner. Replace logs.
NOTE: The type of installation, vent system
confi guration, and wind effects may cause the fl ame patterns to vary.

CLEANING AND MAINTENANCE
VENT SYSTEM
The fireplace and venting system should be inspected before initial use and at least annually by a qualified field service
person. Inspect the external vent cap on a regular basis to make sure that no debris is interfering with the airflow. Inspect
entire venting system to ensure proper function.
GLASS DOOR
Thoroughly clean the inside of the glass door after using the fireplace for ten hours. Periodically clean the glass door as
necessary.
When cleaning the glass, remember:
• Do not remove the glass when hot. Allow glass to cool before removal.
• NEVER use abrasive materials.
• Keep children and pets a safe distance away.
• Never operate the fireplace without the glass door properly secured.
• Never operate the fireplace if the glass is broken.
• Replace any glass that is chipped, cracked, or broken. Replacement glass door assemblies MUST be supplied by the
fireplace manufacturer – No substitute materials may be used.
• Handle glass door with care to avoid striking or scratching it on hard objects.
To clean glass door, follow “Glass Removal” procedure outlined in the Final Installation section. Film deposit on the inside
of the glass should be cleaned off using a nontoxic, non-corrosive, non-abrasive, mild-cleaning solution. Simply apply an
adequate amount to the glass and wipe off with a damp cloth. After all maintenance has been completed, re-install glass
door.
LOGS
Leave logs installed in the fireplace for cleaning. Vacuum surface of the logs with a brush attachment. If logs must be removed
for cleaning, handle carefully by holding gently at each end. Gloves are recommended to prevent skin irritation from ceramic
fibers. If skin becomes irritated, wash gently with soap and water. Vacuum surface of logs with brush attachment or brush
logs with a soft bristle brush (i.e. clean, dry paintbrush). To place logs back in the fireplace, see “Log Placement” found in
the Final Installation section.
NOTE: Do not use fl uids to clean ceramic fi ber logs.
