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.

or when such a standard is not applicable, the
, or
.
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 replace to give off
some odor the rst time it is burned. This is due
to the manufacturing process.

Plan for the installation of your appliance. This includes
determining where the unit is to be installed, the vent con-
guration 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, includ-
ing 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. See Figure 3 for sug-
gested locations.
• Location should be out of high trafc areas and away
from furniture and draperies due to heat from appli-
ance.
• 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. See Venting section found in this
manual for allowable venting congurations.
• These units can be installed in a bedroom. Refer to the
National Fuel Gas Code ANSI Z233.1/NFPA 54 — (cur-
rent edition), the Uniform Mechanical Code — (current

The replace must be secured to the oor and/or to framing
studs as shown in Figure 6. Use two (2) wood screws or
masonry/ concrete screws to secure replace to the oor.
Use four (4) screws to attach replace to framing. The side
nailing anges are 1/2" or 5/8" to accommodate different
wall thickness.
: 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 painted face of the appliance. It is
permissible to bring combustible wall board to the top of
the standoffs on the top and to the wall board stand-offs
on the sides of the unit. A 300°F minimum adhesive may
be used to attach facing materials 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.

Consult local building codes before beginning the
installation. The installer must make sure to select the
proper vent system for installation. The approved 5 x
8 venting components are Duravent and Selkirk
products listed on Page 49. UL1777 exible venting
is also approved for use on these models. Before
installing vent kit, the installer must read this replace
manual and vent kit instructions.
Only a qualied installer/service person should install
venting system. The installer must follow these safety
rules:
• Wear gloves and safety glasses for protec-
tion.
• 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
or approved by Vermont Castings Group.
• Installation other than permitted by these instruc-
tions.

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 feet of vertical rise from the oor
of the replace. With 7Z\x feet or more vertical rise from
the oor of the replace, the horizontal run may run 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 15.
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.
Refer to 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).

The Vent Graph, showing the relationship between vertical
and horizontal side wall venting, will help to determine the
various dimensions allowable. Figure 10
Horizontal and vertical sections of this vent system
require a minimum of 1" clearance to combustibles at the
top, sides and bottom.
When vent exits through foundations less than 20" below
outcrop, the termination must be ush up with outcropped
wall above.
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.
• The maximum number of 90° elbows per side wall
installation is three (3). Figure 14
• A minimum of 12" is required before a 90° elbow. If a 90°
elbow is tted directly after 12" vertical section mounted
to the top of the replace, the maximum horizontal vent
run before the termination or a vertical rise is 36” (914
mm). Figure 15

• 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

by 36". Figures 16 and 17. This does not apply if the 90°
elbows are used to increase or redirect a vertical rise.
Example: According to the vent graph (Page 13) the maxi-
mum horizontal vent length in a system with a 10' vertical
rise is 17Z\x’ (5.3 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" (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 12" vertical rise is neces-
sary. The maximum horizontal run with the 12” 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 12".
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
18
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. Figure 18

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
22 to avoid cutting load bearing members.
For optimal ame 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
rst section of ue 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.
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 21 and 22.
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" x 10Z\x" (241 x 241 mm) inside dimen-
sions as shown in Figure 24 using framing lumber the
same size as the ceiling joist. If the area above the ceil-
ing 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 23. Otherwise,
install restop below the framed hole. Figure 24
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
cutting hole in roof). The 10Z\x"x10Z\x" (241 x 241 mm)
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.
Figure 22
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.

1. Flexible UL1777 listed venting may be used in any
venting application where rigid direct vent components
can be used.
Flex kits may not be modied. Flex
kits may be added to the end of a vent run made of rigid
vent sections using pipe manufacturer's approved ex
to pipe adapters. This may occur only if doing so does
not violate any of the venting length, height, routing,
horizontal to vertical ratio requirements or clearance
considerations detailed in this manual.
2. The ex adapter starter kit (DVFF8A/8) is used to attach
ex venting to the appliance starting collar. It includes
5" inner and 8" outer adapter rings. Figure 26
• The inner and outer adapter rings are required to
start all ex runs.
• Never install damaged or torn exible venting.
• Over tightening clamps may rip, tear, or otherwise
damage exible venting.
• The adapter kit does not include individual pipe sec-
tions which may be purchased separately. (UL1777
listed type venting only.)
3. Start the exible vent as follows:
A. Installing the inner ex adapter and pipe. Figure
26
1. Insert the long side of the 5" inner ring into
exhaust pipe, gently tap to seat into place, and
secure with screws.
2. Slide the small gear clamp over the inner exible
vent pipe, and push out of the way.
3. Pull and extend the inner exible vent.
4. Slide the inner vent onto the adapter collar, for a
minimum 1C\v" overlap.
5. Locate the clamp at approximately 3/4" from the
ex end and tighten.
6. Secure the clamped inner section with three self-
tapping screws, drilled equidistant, just above the
clamp perimeter.
B. Installing the outer ex pipe. Figure 26
1. Firmly insert the 8" outer adapter ring into the
outer appliance starting collar and secure with
screws.
