FIREBOX FRAMING
Firebox framing can be built before or after the appliance
is set in place. Construct rebox framing following Figure
5, 6 or 7 for your specic installation requirements. The
framing headers may rest on the top of the rebox standoffs. Do not bring headers below top of standoffs. NOTE:
When planning your framing and installation, keep in mind
that the gas line and electric power come in on the same
end of the replace. Refer to Figures 2, 3 & 4 for replace
dimensions.
The rebox may be installed directly on a combustible oor
or raised on a platform of an appropriate height. When
the rebox is installed directly on carpeting, tile, or other
combustible material, other than wood ooring, the rebox
shall be installed on a metal or wood panel extending the
full width and depth of the enclosure.
FINISHING MATERIAL
NOTE: Any remote wiring (i.e. remote control, wall switch,
and optional fan) must be done prior to nal nishing to
avoid costly reconstruction.
Only noncombustible materials (i.e. brick, tile, slate, steel,
or other materials with a UL re rating of Zero) may be
used to cover the black surface of the appliance. A 300°F
minimum adhesive may be used to attach facing materi-
als to the black surface. If joints between the nished wall
and the replace surround are sealed, a 300°F minimum
sealant material (General Electric RTV103 or equivalent)
must be used.
Do not fill spaces around firebox with
insulation or other materials. This could
cause a re.
WARNING
20306750
COLD CLIMATE INSULATION
If you live in a cold climate, seal all cracks
around your appliance, and wherever cold air
could enter the room, with noncombustible
material. It is especially important to insulate
NOTE
the outside chase cavity between the studs
and under the oor on which the appliance
rests, if the oor is above ground level.
NOTE: Refer to cold climate pilot information on Page 46
for more information on standing pilot vs. intermittent pilot
options.

VENTING INSTALLATION
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 1/4" rise for every 12" of run towards
the termination below 71⁄2' of vertical rise from oor of re-
place. With 71⁄2 feet or more of vertical rise from the oor
of the replace, the horizontal run may be level. NEVER
run vent piping down.
You may use up to three 90° elbows in this vent conguration. Refer to Vertical/Horizontal Termination Congurations
on Page 21.
Horizontal venting which incorporates the twist lock pipe
must be installed on a level plane without an inclining or
declining slope.
FOR VERTICAL TERMINATION
Measure the distance from the replace oor to the ceiling. Add the ceiling thickness, the vertical rise in an attic
or second story, and allow for sufcient vent height above
the roof line.
NOTE: 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°.
Designer Series Direct Vent Gas Fireplace
Never run the vent pipe down. This may
cause excessive temperatures which could
cause a re.
WARNING
For two-story applications, restops are required at each
oor 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 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 bal-
ance between the combustion air intake and the ue gas
exhaust. Certain limitations apply to vent congurations
and must be strictly followed.
INSTALLING A VENT SYSTEM IN AN
OUTSIDE CHASE
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.
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
NOTICE
material. Maintain proper clearances to all
combustible materials.
Always maintain minimum clearances around
vent systems. The minimum clearances to
combustibles for horizontal vent pipe are 3"
at the top* and 1" at the sides and bottom
of the vent system until the pipe penetrates
the nearest vertical wall (1" required). A 1"
minimum clearance all around the pipe must
be maintained at outside wall and on vertical
runs. Do not pack the open air spaces with
insulation or other materials. This could
WARNING
cause high temperatures and may present
a re hazard.
*Unless the vertical run is 7
1
⁄2 feet or higher
from oor of replace, the clearance for the
horizontal run is 1" on all sides.
20306750
Treatment of restops and construction of
the chase may vary from building type to
building type. These instructions are not
substitutes for the requirements of local
NOTICE
building codes. You must follow all local
building codes.

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 replace in accordance with same.
Example: If the vertical dimension from the oor of the
replace is 11' (3.4 m) the horizontal run to the face of
the outer wall must not exceed 16' (4.9 m).

VENTING ONLY)
When installed as a rear vent unit, this appliance may be
vented directly to a termination located on the rear wall
behind the appliance. Only an Vermont Castings Group
brand termination is allowed for this application.
• The maximum horizontal distance between the rear
of the appliance and the termination is 20" (508 mm).

• Only one 45 degree elbow is allowed in these installa-
tions.
1. Rigid vent pipes and ttings have special twist-lock
connections. Assemble the desired combination of pipe
and elbows to the appliance adapter.
Twist-Lock Procedure: The female ends of the pipes
and ttings have three (3) locking lugs (indentations).
These lugs will slide straight into matching slots on
the male end of adjacent pipes and ttings. Push the
pipe sections together and twist one section clockwise
approximately one-quarter turn until the sections are
fully locked. Figure 20

2. Refer to venting and termination instructions for further
instructions.
3. Locate and cut the vent opening in the wall. For combustible walls rst frame in opening.
Combustible Interior Walls: Cut a 121/2" x 101/2" hole
through the interior wall.
Combustible Exterior Walls: Cut a 101/2" x 101/2"
square hole through the exterior wall frame. Figure 21
Noncombustible Walls: Hole opening should be 81/2"
(216 mm) in diameter.
4. The center of the hole should align with the center line
of the horizontal rigid vent pipe end. Allow 1/4" minimum
rise per foot. Figure 21

5. Apply a bead of non-hardening mastic around the
outside edge of vent cap. Position the vent cap in the
center of hole on the exterior wall with the word "UP"
on the vent cap facing up. Insure proper clearance of
1" to combustibles is maintained. Attach the vent cap
with four (4) wood screws supplied. Figure 22
NOTE: Replace the wood screws with appropriate
fasteners for stucco, brick, concrete or other types
of siding.
For vinyl siding, stucco or wood exterior, use vinyl
siding standoffs between vent cap and exterior wall for
Duravent or Selkirk Terminations only. The vinyl siding
standoff prevents excessive heat from melting the
vinyl siding material. NOTE: Vermont Castings Group
Termination does not require standoff. Bolt the vent
cap to the standoff or wall. Apply non-hardening mastic
around outside edge of the standoff instead of the vent
cap assembly. Use wood screws provided to attach the
standoff. Figure 23
