monoxide poisoning are similar to the u with headaches,
dizziness and/or nausea. If you have these signs, the re-
place may not have been installed properly. Get fresh air
at once! Have the replace inspected and serviced by a
qualied 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 inuence 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 replace.

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 congu-
ration. Refer to Horizontal Termination Congurations on
Pages 22 and 23.
Measure the distance from the replace oor to the ceil-
ing. Add the ceiling thickness, the vertical rise in an attic
or second story, and allow for sufcient 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, 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. 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 bal-
ance between the combustion air intake and the ue gas
exhaust. Certain limitations apply to vent congurations
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 exiting through the outer wall. Using this dimen-
sion 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 re-
place in accordance with same.
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 14' (4.3 m).
If the vertical dimension from the oor of the
unit is 7’ (2.14m), the horizontal run to the face of the
outer wall must not exceed 8Z\x' (2.6 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 17
• Only one 45° elbow is allowed in these installations.
1. Locate and cut the vent opening in the wall. For
combustible walls rst 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 18
Hole opening should be 7Z\x"
(190 mm) 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. Figure 19
3. Attach vent pipe assembly to the replace. Set replace
in front of its permanent location to insure minimum
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 18. The center of
the hole should line up with the center line of the hori-
zontal rigid vent pipe end. Be sure to allow for minimum
rise. Cut a 11Z\x"x9Z\x" rectangle hole through combus-
tible exterior wall (7Z\x" diameter hole if noncombustible).
Frame as necessary. Allow 1/4" minimum rise per foot.

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 word “UP”
on the vent cap facing up. Insure proper clearance of
1" to combustibles is maintained. Attach the vent cap
with four wood screws supplied. Figure 20
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. 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 pro-
vided to attach the standoff. Figure 21
5. Slide re stop over the vent pipe before connecting
horizontal run to vent cap. Figure 22
6. Insert vent pipe into the horizontal termination. The pipe
overlap should be a minimum of 1Z\v". Fasten all vent
connections with screws provided.
7. Slide re stop against the interior wall surface and attach
with screws. Figure 22

The Vent Graph, showing the relationship between vertical
and horizontal side wall venting, will help to determine the
various dimensions allowable. Figure 23
When vent termination exits through foundations less than
20" below siding outcrop, the vent pipe must ush up with
the siding.
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
he Transition Elbow) to the face of the outer wall.
• The maximum number of 90° elbows per side wall
installation is three (3). Figure 24
• If a 90° elbow is tted directly on top of the replace
ange the maximum horizontal vent run before the ter-
mination or a vertical rise is 36” (914 mm). Figure 25 Figure 23 -

• If a 90° elbow is used in the horizontal vent run, the hori-
zontal vent length is reduced by 36" (914 mm). Figure
26. This does not apply if the 90° elbows are used to
increase or redirect a vertical rise. Figure 26
According to the vent graph, Figure 23, the
maximum horizontal vent length in a system with a 7.5'
vertical rise is 20’ (6 m) and if a 90° elbow is required in
the horizontal vent it must be reduced to 17' (5.2 m). Refer
to Page 17 “How to Use Vent Graph.”
In Figures 27 and 28, 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 26

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 nec-
essary. The maximum horizontal run with the 24” vertical
pipe is 36". This measurement is taken from the collar of
the replace (or transition elbow) to the face of the exterior
wall. Refer to the Sidewall Venting Graph for extended
horizontal run if the vertical exceeds 24".
1. Establish vent hole through the wall. Refer to Page 18,
Figure 18
2. Remove soil to a depth of approximately 16" below base
of snorkel. Install drain pipe. Install window well (not
supplied). Rell hole with 12" of coarse gravel leaving
a clearance of approximately 4" below snorkel. Figure

If the foundation is recessed, use recess brackets (not
supplied) for securing lower portion of the snorkel. Fasten
brackets to wall rst, then secure to snorkel with self drill-
ing #8 x 1/2" sheet metal screws. It will be necessary to
extend vent pipes out as far as the protruding wall face.
