ANSI Z223.1/NFPA 54 and/or local codes having jurisdiction.
In Canada, please consult provincial and/or local authorities having jurisdiction for installations at elevations
above 4,500 feet (1,370 m).
COLD CLIMATE OPTION (IPI Models Only)
NOTE: 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 the outside chase cavity between the studs and
under the oor on which the appliance rests, if the oor is
above ground level.
Your replace is equipped with an intermittent pilot ignition
(IPI) control. An IPI control with a standing pilot option pro-
vides the dual benet of an economical and environmentally
responsible product and one which lights easily even in
the coldest climates. When in intermittent pilot mode (as
it comes from the factory), your pilot remains unlit until
needed, saving you fuel. Standing pilot mode, by com-
parison, is characterized by a continuously burning pilot.
The benet of a pilot which lights only when needed is fuel
savings. However, with no pilot burning in your replace,
units operating in colder climates may experience delayed
start up or lock out. Because colder air is heavier than
milder air and there is no pilot burning to maintain a warm
stable temperature in your rebox, establishing a draft to
aid ignition becomes difcult. This is perfectly normal but
can be somewhat frustrating.
To remedy this issue, your replace has been designed with
a cold climate pilot option, which, when active, maintains
a warmer temperature inside your rebox to make ignition

faster and more efcient. Operating your appliance in cold
climate (aka standing) pilot mode will prohibit the need for
multiple ignition attempts and will prevent the system from
delaying start up or locking out.
Cold Climate Switch
To activate the cold climate option, simply move the cold
climate toggle switch located on the right side of the black
control center to the “On” (left) position. (Figure 1) You can
operate your appliance in this mode regardless of whether
you are using a remote control, wall switch or thermostat.

WARNING
Read all instructions completely and thoroughly
before attempting installation. Failure to do so
could result in serious injury, property damage or
loss of life. Operation of improperly installed and
maintained venting system could result in serious
injury, property damage or loss of life.
WARNING
This replace must be vented to the outside.
The venting system must NEVER be attached
to a chimney serving a separate solid fuel
burning appliance. Each gas appliance must
use a separate vent system. Do not use common
vent systems.
WARNING
Do not pack the open air spaces with insulation or
other materials. This could cause high temperatures
and may present a re hazard.
NOTICE: Failure to follow these instructions will void the
warranty.
INSTALLATION PRECAUTIONS
Consult local building codes before beginning the
installation. The installer must make sure to select the
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 venting 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 venting system:
GENERAL VENTING
Your replace is approved to be vented either through the
side wall, or vertical through the roof.
• Only Vermont Castings Group venting components
specically approved and labeled for this replace
may be used.
• Flexible UL1777 listed venting may be used in any vent-
ing application where rigid direct vent components can
be used. All restrictions, clearances and allowances that
pertain to the rigid piping apply to the exible venting.
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.
• Venting terminals shall not be recessed into a wall or sid-
ing.
• Vertical side wall venting in horizontal applications must
be installed with a 1/4" rise for every 12" of run.
• Select the amount of vertical rise desired. All horizontal
run of venting must be run level or have 1/4" rise for every
12" (305 mm) of run towards the termination below 71⁄2
feet of vertical rise. With 71⁄2 feet (2.3 m) or more vertical
rise from oor of replace, the horizontal run may run level. NEVER run vent piping downward.
• Horizontal venting which incorporates the use of ex
venting shall have an inclining slope from the unit of 1/2"
(13 mm) per 12" (305 mm).
There must not be any obstruction such as bushes, garden sheds, fences, decks or utility buildings within 24"
(610 mm) from the front of the termination hood.
Do not locate termination hood where excessive snow or
ice build up may occur. Be sure to check vent termination area after snow falls, and clear to prevent accidental
blockage of venting system. When using snow blowers,
make sure snow is not directed towards vent termination
area.
Location of Vent Termination
It is imperative the vent termination be located observing
the minimum clearances as shown on following page.
• 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 instructions.

VENTING INSTALLATION
HOW TO USE THE VENT GRAPH
The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the re-
lationship 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 Side wall Vent Graph, Figure 20, 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 A:
If the vertical dimension from the oor of the unit is 11' (3.4
m) the horizontal run to the face of the outer wall must not
exceed 14' (4.3 m).
EXAMPLE B:
If the vertical dimension from the oor of the unit is 7' (2.1
m), the horizontal run to the face of the outer wall must not
exceed 8' (2.4 m).

SLP PIPE
When using SLP pipe it is not necessary to use sealant
on the joints.
To join SLP pipe together, simply align the beads of the
male end with the grooves of the female end, twisting the
pipe until the ange on the female end contacts external
ange on the male end. NOTE: Sealant is not required to
assemble replace venting. Do not use silicone sealant at
the inner ue exhaust connections.
1. Attach the First Vent Component to SLP Starting
Collars
To attach the rst vent component to the starting collars of the appliance:
• Lock the vent components into place by sliding the
pipe section onto the collar.
• Align the seam of the pipe and seam of collar to allow
engagement. Rotate the vent component to lock into
place. Use this procedure for all vent components.
See Figure 21.
• Continue adding vent components, locking each
succeeding component into place.
• Ensure that each succeeding vent component
is securely tted and locked into the preceding
component.
2. Commercial or High-Rise Applications
For installation into a commercial or high-rise application: All outer pipe joints must be sealed with high
temperature aluminum foil tape, including the slip sec-
tion that connects directly to the horizontal termination
cap.
• Only outer pipes are to be sealed. Do not seal the
inner ue. All unit collar, pipe, slip section, elbow
and cap outer ues shall be sealed in this manner,
unless otherwise stated.

ADDITIONAL ASSEMBLY INSTRUCTIONS
1. Assemble Slip Sections
The outer ue of the slip section should slide over the
outer ue of the pipe section and into the inner ue of
the last pipe section (see Figure 22A).
Slide together to the desired length, making sure that
a 11⁄2 in. outer ue overlap is maintained between the
pipe section and slip section.
The pipe and slip section need to be secured by driving two 1⁄2 in. screws through the overlapping portions
of the outer ues using the pilot holes (see Figure 23).
This will secure the slip section to the desired length
and prevent it from separating. The slip section can
then be attached to the next pipe section.
If the slip section is too long, the inner and outer ues
of the slip section can be cut to the desired length.

Figure 23–
Screws into Slip Section
WARNING! Risk of Fire/Explosion! DO NOT
break seals on slip sections. Use care when removing termination cap from slip pipe. If slip section
seals are broken during removal of the termination
cap, vent may leak.
Figure 22A–
Slip section pilot holes
Make sure the seams are not aligned to prevent unintentional
disconnection.
(see Figure 22B)
2. Secure the Vent Sections
Vertical sections of SLP pipe must be supported every
8 ft.
The SLP restop includes tabs that may be used to
secure vertical sections.
The vent support or plumber’s strap (spaced 120°
apart) may be used to secure the vertical sections of
pipe (see Figure 24).
Horizontal sections of vent must be supported every
5 ft with a vent support or plumber’s strap (see Figure
8).
WARNING! Risk of Fire/Explosion/Asphyxiation!
Improper support may allow vent to sag and
separate. Use vent run supports and connect vent
sections per installation instructions. DO NOT allow
vent to sag below connection point to appliance.

Follow Steps 1 and 2 on Page 20.
Step 3
Install the 4" (102 mm) ex vent pipe to the appliance collars described in the General Information Assembling Vent
Pipes section of this manual. If the installation requires a
45° angle, grasp the vent pipe close to the appliance collar
and bend to 45°. DO NOT exceed 45°. Figure 32
Install the 7" vent pipe in the same manner as Step 2.
NOTE: There must be a 1⁄2" (13 mm) rise in a 12" (305
mm) length of ex vent. Figure 33
Step 4
Assemble the ex vent to the collars on the termination as
you did on the appliance.

TOP VENT SIDE WALL APPLICATION
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 congurations apply and must be strictly adhered to.
The Vent Graph, showing the relationship between verti-
cal and horizontal side wall venting, will help to determine
the various dimensions allowable.
Minimum clearance between vent pipes and combustible materials is 3" (76 mm) on top, and 1" (25 mm) on
the bottom and sides unless otherwise noted.
When vent termination exits through foundations less
than 20" (508 mm) 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 the
Transition Elbow) to the face of the outer wall.
Horizontal plane means no vertical rise exists on this portion of the vent assembly.
When installing the appliance as a rear vent unit, the
90° or 45° Transition Elbow attached directly to the
rear of the unit is NOT INCLUDED in the following cri-
teria and calculations, and unless specically mentioned should be ignored when calculating venting
layouts.
• The maximum number of 90° elbows per side wall in-
stallation is three (3). Figure 34
• 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 35
• If a 90° elbow is used in the horizontal vent run (lev-
el height maintained) the horizontal vent length is re-
duced by 36" (914 mm). Figures 36 & 37. This does
not apply if the 90° elbows are used to increase or
redirect a vertical rise. Figure 34
