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.

It is normal for replaces 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 replaces to give off some odor
the rst time it is burned. This is due to the manufacturing
process.
It is recommended that you burn your replace for at
least ten (10) hours the rst time you use it. Place the
fan switch in the “OFF” position during this time.

Plan for the installation of your appliance. This includes determining where the unit is to be installed,
the vent conguration to be used, framing and nishing details, and whether any optional accessories
(i.e. blower, wall switch, or remote control) are desired. Consult your local building code agency to
ensure compliance with local codes, including permits and inspections.
The following factors should be taken into consideration:
• Clearance to side-wall, ceiling, woodwork, and windows. Minimum clearances to combustibles
• This replace may be installed along a wall, across a corner, or use an exterior chase. Refer to
Figure 3 for suggested locations.
• Location should be out of high trafc areas and away from furniture and draperies due to heat
from appliance.
• Never obstruct the front opening of the replace.
• Do install in the vicinity where gasoline or other ammable liquids may be stored.
• Vent pipe routing. Refer to the Venting section found in this manual for allowable venting con-
gurations.

proper vent system for installation. Before installing vent
kit, the installer must read this replace manual and vent
kit instructions.
Only a qualied installer/service person should install vent-
ing system. The installer must follow these safety rules:
• Wear gloves and safety glasses for protection.
• Use extreme caution when using ladders or when
on rooftops.
• Be aware of electrical wiring locations in walls and
ceilings.
The following actions will void the warranty on your vent-
ing system:
• Installation of any damaged venting component.
• Unauthorized modication of the venting system.
• Installation of any component part not manufactured

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 oor of re-
place. With 7Z\x 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 congura-
tion. Refer to Vertical/Horizontal Termination Congurations
on Page 16.
Horizontal venting which incorporates the twist lock pipe
must be installed on a level plane without an inclining or
declining slope.
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. 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 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.
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).

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 nished outside wall.

• If a 90° elbow is used in the horizontal vent run (level
height maintained) the horizontal vent length is reduced
by 36". Figure 16. This does not apply if the 90° elbows
are used to increase or redirect a vertical rise.
According to the vent graph (Page 14) the maxi-
mum horizontal vent length in a system with a 10' vertical
rise is 17Z\x’ (5.2 m) and if a 90° elbow is required in the
horizontal vent it must be reduced to 14Z\x' (4.4 m).

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" (178mm)
below grade level. The 7" (178mm) 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
replace (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). Rell hole with 12" of coarse gravel leaving
a clearance of approximately 4" below snorkel. Figure

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.

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).
Example: 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 22
• The maximum angular variation allowed in the system
is 270°. Figure 22
• The minimum height of the vent above the highest point
of penetration through the roof is 2' (610 mm).
Install restrictor disc as shown in Figure 21 for vertically
vented applications.
Up to two (2) restrictor discs may be needed for 40' instal-
lation.
The two (2) restrictor discs suppled will work for most instal-
lations. If a third disc is needed order Part No. 56D3027.
This gas replace 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 21
Horizontal sections of this vent system require a
minimum of 3" clearances to combustibles at the top of
the ue and 1" clearance at the sides and bottom until the
ue penetrates the outside wall. A minimum 1" clearance
all around the ue is acceptable at this point of penetration.
Unless the vertical run is 7Z\x feet or higher from oor of
replace, 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

For optimal ame appearance, a restrictor disc is necessary
on straight vertical runs of 10' of more.
• Runs may not incorporate elbows.
• The disc is part number 56D3027 and is included in
installation manual packet.
• Drop the disc into a 5" inner collar before installing
the rst section of ue or install at the last section
before installing the termination. Or disc may be
installed from inside rebox into the 5" inner collar.
• An additional disc may be installed on runs of 35' or more.
Rotate discs 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 22 and 23.
2. Set replace in desired location. Drop a line plumb down
from the ceiling to the position of the ue 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 10Z\x" (241 mm) square hole in the ceiling using the
locating hole as a center point The opening should be
framed to 10Z\x"x10Z\x" (241 x 241 mm) inside dimensions
as shown in Figure 25 using framing lumber the same
size as the ceiling joist. If the area above the ceiling is
an insulated ceiling or a room, nail restop from the top
side. This prevents loose insulation from falling into the
required clearance space. Figure 24. Otherwise, install
restop below the framed hole. Figure 25

2. Assemble the desired lengths of pipe and elbows nec-
essary to reach from the burner system ue up through
the restop. 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 cut-
ting hole in roof). The 101/2"x101/2" (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.
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 21.
Whenever possible, use 45° elbows instead of 90° elbows.
The 45° elbow offers less restriction to the ow of the ue
gases and intake air.
5. Place the ashing over the pipe section(s) extending
through the roof. Secure the base of the ashing to
the roof and framing with roong nails. Be sure roong
material overlaps the top edge of the ashing. 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 rst 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 ll any of the required clearance spaces with
insulation.
