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 fl oor on which the appliance rests, if the fl oor is
above ground level.
Your fi replace is equipped with an intermittent pilot ignition
(IPI) control. An IPI control with a standing pilot option provides the dual benefi t 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 comparison, is characterized by a continuously burning pilot.
The benefi t of a pilot which lights only when needed is fuel
savings. However, with no pilot burning in your fi 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 fi rebox, establishing a draft to
aid ignition becomes diffi cult. This is perfectly normal but
can be somewhat frustrating.
T o remedy this issue, your fi replace has been designed with
a cold climate pilot option, which, when active, maintains
a warmer temperature inside your fi rebox to make ignition

faster and more effi cient. 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.

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
WARNING
venting system could result in serious injury ,
property damage or loss of life.
This fireplace 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.
WARNING
Do not use common vent systems.
Do not pack the open air spaces with
insulation or other materials. This could
cause high temperatures and may present
a fi re hazard.
WARNING
Failure to follow these instructions will
void the warranty.
NOTICE
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 fi replace manual and vent
kit instructions.
Only a qualifi ed 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 venting system:
GENERAL VENTING
Your fi replace is approved to be vented either through the
side wall, or vertical through the roof.
• Only Vermont Castings Group venting components
specifi cally approved and labeled for this fi 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 fl exible venting.
Flex kits may not be modifi ed. Flex kits may be added to
the end of a vent run made of rigid vent sections using
pipe manufacturer's approved fl 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.
• Select the amount of vertical rise desired. All horizontal
run of venting must 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 off top of
fi replace, the horizontal run may run level. NEVER run
vent piping downward.
• Horizontal venting which incorporates the twist lock pipe
must be installed on a level plane without an inclining or
declining slope.
• Horizontal venting which incorporates the use of fl ex
venting shall have an inclining slope from the unit of 1"
(25 mm) per 24" (610 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 modifi cation 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.

TWIST LOCK PIPE
When using twist lock pipe it is not necessary to use sealant on the joints.
To join twist lock pipes together, simply align the beads of
the male end with the grooves of the female end, twisting
the pipe until the fl ange on the female end contacts exter-
nal fl ange on the male end. It is recommended that you
secure the joints with three (3) sheet metal screws, however, this is not mandatory with twist lock pipe. Figure 18
NOTE: Sealant is not required to assemble fi replace
venting. Do not use silicone sealant at the inner fl ue
exhaust connections.
To make it easier to assembly the joints, we suggest putting a lubricant (V aseline or similar) on the male end of the
twist lock pipe prior to assembly.

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 exiting through the outer wall. Using this
dimension on the Side wall Vent Graph, Figure 21, 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 fi re-
place in accordance with same.
EXAMPLE A:
If the vertical dimension from the fl oor of the unit is 1 1' (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 fl 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).
Refer to Page 23 for snorkel requirements.

REAR WALL VENT APPLICATIONS
When installed as a rear vent unit this appliance may be
vented directly to a termination located on the rear wall
behind the appliance.
• Only Vermont Castings Group approved venting com-
ponents are approved to be used in these applications
(Refer to ‘Venting Components’ listed for different installation requirements).
• The maximum horizontal distance between the rear of
the appliance (or end of the transition elbow in a corner application) and the outside face of the rear wall is
20" (508 mm). Figure 23
• Only one 45° elbow is allowed in these installations.
• Minimum clearances between vent pipe and combus-
tible materials are as follows:
Top – 3" (76 mm), except at outside wall 1" (25 mm)

Step 3
Measure the horizontal length requirement for the venting
including a 2" (51 mm) overlap, i.e. from the elbow to the
outside wall face plus 2" (51 mm). Figure 25
Step 4
Install the 4" (102 mm) vent to the appliance collar and
secure with 3 sheet metal screws. Install the 7" (178 mm)
vent pipe to the appliance collar and secure with 3 sheet
metal screws. It is not necessary to seal this connection.
If a 45° elbow is being used attach the elbow to the appliance in the same manner then attach the venting to the
elbow.
It is critical that there is no downward slope
away from the appliance when connecting
the vent or elbow.
Step 5
Guide the venting through the vent hole as you place the
appliance in its installed position. Guide the 4" (102 mm)
and 7" (178 mm) collar of the vent termination into the
outer ends of the venting. Do not force the termination. If
the vent pipes do not align with the termination, remove
and realign the venting at the appliance fl ue collars. Fig-
ure 25. Attach the termination to the wall as outlined in the
instruction sheet supplied with the termination.
