VENT 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.
You may use up to three 90° elbows in this vent conguration. See
Horizontal Termination Congurations on pages 19 and 20.
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 sufcient 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°.
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 balance between the combustion air intake and the ue gas exhaust.
Certain limitations apply to vent congurations 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.
Never run the vent pipe level or downward.
This may cause excessive temperatures which
could cause a fire.
WARNING
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.
NOTICE
Treatment of firestops 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.

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 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 replace in
accordance with same.
Example: If the vertical dimension from the floor of the
fireplace 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 floor of the unit
is 7’ (2.14m), the horizontal
wall must not exceed 7' (2. 14 m).

REAR WALL VENT INSTALLATION
When installed as a rear vent unit this appliance may be vented directly to a termination located on the rear wall behind
the appliance with 3' of vertical rise minimum.
• The maximum horizontal distance between the rear of the appliance and the outside of termination is 20" (508 m). See
Figure 11.
• NOTE: A 30° elbow on 2 foot minimum vertical pipe is required for this configuration.
VENTING INSTALLATION
1. Locate and cut the vent opening in the wall. For com-
bustible walls rst frame in opening. See Figure 11.
Combustible Walls: Cut a 91⁄2"H x 91⁄2" W
(241mm x 241mm) hole through the exterior wall
and frame as shown. See Figure 12.
Noncombustible Walls: Hole opening should be
71⁄2" (190mm) in diameter.
2. Rigid vent pipes and ttings 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 oor.
Twist-lock Procedure: The female ends of the pipes
and ttings have three 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. See Figure 13.
3. Attach vent pipe assembly to the replace. Set re-
place in front of its permanent location to insure
minimum clearances. Mark the wall for a 91⁄2"H
x 91⁄2"W (241mm x 241mm) rectangle hole (for
noncombustible material such as masonry block or
concrete, a 71/2" [190mm] diameter hole is accept-
able). See Figure 11. 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 91/2"x91/2" (241mm X 241mm) rectangle hole through combustible
exterior wall (71/2" [190mm] diameter hole if noncombustible). Frame as necessary. Allow 1/4" minimum rise per foot. See
Figure 12.

4. 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 arrow up on the vent cap.
Insure proper clearance of 1" to combustibles is main-
tained. Attach the vent cap with four wood screws supplied.
See Figure 14.
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 stand-
offs between vent cap and exterior wall. The vinyl siding standoff
prevents excessive heat from melting the vinyl siding material. Bolt
the vent cap to the standoff. Apply non-hardening mastic around
outside edge of the standoff instead of the vent cap assembly. Use
wood screws provided to attach the standoff. See Figure 15.
5. Slide the wall thimble over the vent pipe before connecting
the horizontal run to the vent cap. See Figure 16.
6. Carefully move the replace with vent assembly attached
toward the wall and insert the vent pipe into the horizontal
termination. The pipe overlap should be a minimum of 11/4".
Apply silicone to the outer pipe connection. Fasten all vent
connections with screws provided.
7. Slide the wall thimble against the interior wall surface and
attach with srews. See Figure 16.

VENT INSTALLATION
HORIZONTAL TERMINATION CONFIGURATIONS — RIGID VENTING
Since it is very important that the venting system maintain its balance between the combustion air intake and the ue gas
exhaust, certain limitations as to vent congurations 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 page 16.
Minimum clearance between vent pipes and combustible materials is 4" on top and 1" from bottom and sides unless
otherwise noted.
When vent terminations exit through foundations less than 20" below siding outcrop, the vent pipe must ush up with the sid-
ing.
It is best to locate the replace 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 ue collar of the replace (or the top of the Transition
Elbow) to the face of the outer wall.
Figure 18 - Maximum Three (3) 90 Elbows
Per Installation
• The maximum number of 90° elbows per side wall installation is three (3), the maximum horizontal run is 20" (Figures 18, 19)

• If a 90° elbow is used in the horizontal vent run (level height
maintained) the horizontal vent length is reduced by 36" (914
mm) (Fig. 20 A and B) This does not apply if the 90° elbows
are used to increase or redirect a vertical rise. See Figure 19.
Example: According to the vent graph (page 16) the maximum
horizontal vent length in a system with a 7.5' vertical rise is 15’
(6m) and if a 90° elbow is required in the horizontal vent it must
be reduced to 12'.
In Figures 20 and 21, 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°.
