PRODUCT FEATURES
These are a few facts that can help you understand and enjoy your direct vent fireplace:
• The venting system may be routed to the
outside of your home in several ways. It
may vent through the roof (vertical) or it
may vent to an outside/exterior wall (horizontal). The vent pipe installation is very
important to allow for proper operation.
You must follow the venting instructions
very carefully for either vertical or horizontal
applications.
• This fireplace may be installed in any room
of your house provided all local codes and
these installation instructions are followed.
PRE-INSTALLATION
LOCA TION AND SPACE
REQUIREMENTS
Determine the safest and most efficient location for your direct vent fireplace. Make sure
that rafters and wall studs are not in the way of
the venting system. Choose a location where
the heat output is not affected by drafts, air
conditioning ducts, windows or doors. Figure
2 shows some common locations. Be aware
of all restrictions and precautions before
deciding the exact location for your fireplace
and termination cap.
When deciding the location of your fireplace,
follow these rules:
• Do not connect this fireplace venting to a
chimney flue serving a separate solid-fuel
burning fireplace or appliance.
• Due to high temperatures, do not locate this
fireplace in high traffic areas, windy or drafty
areas or near furniture or draperies.
• Proper clearances must be maintained.
Flush with a wall
• Each time you turn on your fireplace, you
may notice some amount of condensation
on the inside of the fireplace glass. This
is normal and will disappear after 10-20
minutes of operation.
• Your direct vent gas fireplace system
(fireplace and venting) is a balanced and
sealed gas operating unit. It requires approximately 10-20 minutes of operating
time before the flame pattern stabilizes.
• Models ending in -C have a standard glass
inner door. Models ending in -CC have the
standard glass inner door with a middle
glass door and outer cool touch glass
door.
• If your fireplace is to be installed directly on
carpeting, vinyl tile or any combustible material other than wood, it must be installed on a
metal or wood panel extending the full width
and depth of the fireplace (see Figure 3).
• Your fireplace is designed to be used in
zero clearance installations. Wall or framing material can be placed directly against
any exterior surface on back, sides or top
of your fireplace, except where standoff
spacers are integrally attached. If standoff
spacers are attached to your fireplace,
these spacers can be placed directly
against wall or framing material. See framing details, page 6.
• When locating termination cap, it is important to observe the minimum clearances
shown in Figure 7, page 7.
• If recessing into a wall, you can avoid extra
framing by positioning your fireplace against
an already existing framing member.
• Do not recess termination cap into a wall
or siding.
• You may paint the termination cap with
450º F (232º C) heat-resistant paint to
coordinate with the exterior finish.
• There must not be any obstruction such as

bushes, garden sheds, fences, decks or
utility buildings within 24" from the front of
the termination cap and the front of outside
air vent.
• Do not locate termination cap and outside
air vent where excessive snow or ice build
up may occur. Be sure to clear vent termination area after snow falls to prevent
accidental blockage of venting system.
When using snow blowers, do not direct
snow towards vent termination area.
CLEARANCES
Minimum clearances to combustibles for the
fireplace are as follows:
*Back and sides 0"
Perpendicular walls 6"
Floor 0"
Ceiling to louver opening
Front 36"
Top of Standoffs 0"
Vent (See venting instructions
for specific venting
clearances.)
Combustible material with a maximum thickness of 5/8" may be flush with the top front
of fireplace.
* For back and sides of fireplace, do not pack
with insulation or other materials. 0" clearance to combustible materials are for framing
purpose only.
NOTICE: This fireplace is intended for use as supplemental heat.
Use this fireplace along with
your primary heating system.
Do not install this fireplace as
your primary heat source. If you
have a central heating system,
you may run system’s circulating blower while using fireplace.
This will help circulate the heat
throughout the house.

VENTING INSTALLATION
NOTICE: Read these instructions completely before attempting installation.
These models are tested and approved for
use with FMI PRODUCTS, LLC (direct vent)
pipe components and terminations.
The venting system must terminate on the
outside of the structure and can not be attached to a chimney or flue system serving a
separate solid fuel or gas burning appliance.
A direct vent appliance must have its own
venting system. DO NOT common vent this
appliance.
These models are approved to be vented
either horizontally through an outside wall or
vertically through a roof or chase enclosure
using the following guidelines:
• When venting system terminates horizontally on an outside wall, you may install
a standoff if the termination cap is to be
installed directly on a combustible finish
such as vinyl, wood, stucco, etc.
• Never run the vent downward as this may
cause excessive temperatures which could
cause a fire.
• Vent pipe air space clearances to combustibles are 1" on all sides except on the
horizontal sections, which requires 2" clearance from the top of the pipe. Where the
termination cap penetrates a combustible
wall, 1" air space clearance is required.
• Have fireplace and selected vent compo-
nents on hand to help determine the exact
measurements when elbowing or offsetting.
Always use wall firestops when penetrating
walls and firestops when penetrating ceil-
ings or attic spaces.
• For installation of fireplace at elevations of
4000 feet or greater, pay special attention
to venting requirement recommendations.
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.
NOTICE: Do not seal termination
cap to vent pipe. Cap must be
removable for vent inspection
and maintenance.
INSTALLATION PRECAUTIONS
• Wear gloves and safety glasses for
protection
• Use extreme caution when using ladders
or when on roof tops
• Be aware of electrical wiring locations in
walls and ceilings
The following actions will void the warranty
on your venting system:
• Installation of any damaged venting
component
• Unauthorized modification of the venting system (Do not cut or alter vent components)
• Installation of any component part not
manufactured or approved by FMI
PRODUCTS, LLC
• Installation other than as instructed by
these instructions
WARNING: This gas fireplace
and vent assembly must be
vented directly to the outside.
The venting system must NEVER
be attached to a chimney serving a separate solid fuel burning
appliance. Each direct vent gas
appliance must use a separate
vent system. Do not use common vent systems.
WARNING: Vent pipe air
space clearances to combustibles are 1" on all sides except
on the horizontal sections,
which require 2" clearances
from the top of the pipe. Where
the termination cap penetrates
a combustible wall, 1" air space
clearance is required.

There are two basic types of direct vent
installation:
• Horizontal Termination
• Vertical Termination
Outside air flex installation is required for
both horizontal and vertical installation (see
page 13).
Horizontal Termination Installation
IMPORTANT: Horizontal square terminations
require only inner portion of wall firestop. Horizontal installations using round termination
require exterior portion of wall firestop.
1. Set fireplace in its desired location and de-
termine the route your horizontal venting
will take. Do not secure fireplace until all
venting has been installed. Some installations require sliding fireplace in and out
of position to make final venting connections. Figures 14 and 15 on page 12 show
different configurations for venting with
horizontal termination that will help you
decide which application best suits your
installation. Check to see if wall studs or
roof rafters are in the path of your desired
venting route. If they are, you may want
to adjust location of fireplace.
2. Direct vent pipe sections and components
are designed with special twist-lock connections.
Twist-Lock Procedure: Female ends of
pipes have locking lugs (indentations).
These lugs will slide straight into matching slots on male ends of adjacent pipes.
Push pipe sections together and twist
one section clockwise approximately onequarter turn until sections are fully locked
(see Figure 8).
Note: Horizontal runs of vent must be sup-
ported every three feet. Use wall straps
for this purpose.
3. Assemble desired combination of pipe
and elbows to fireplace flue collar . If there
are long portions of venting run, pre-assembled pipe sections may be installed
as subassemblies for convenience.
4. Carefully determine location where vent
pipe assembly will penetrate outside wall.
VENTING INSTALLATION

Center of hole should line up with center
line of horizontal vent pipe. Mark wall for
an 11 1/2" x 11 1/2" square hole. Cut and
frame square hole in exterior wall where
vent will be terminated. If wall being penetrated is constructed of noncombustible
material, such as masonry block or concrete, a 8
acceptable (see Figure 9).

This will cause a fire hazard.
5. Noncombustible Exterior Wall: Position
horizontal vent cap in center of the 8
round hole and attach to exterior wall
with four wood screws provided. Before
attaching vent cap to exterior wall, run a
bead of non-hardening mastic (pliable
sealant) around outside edges to make a
seal between it and outside wall.
Note: Four wood screws provided should
be replaced with appropriate fasteners for
stucco, brick, concrete or other types of
sidings (see Figure 10).
Combustible Exterior Wall: For vinyl
siding, stucco or wood exteriors, a siding
standoff may be installed between vent
cap and exterior wall. Siding standoff
prevents excessive heat from damaging
