poisoning may lead to death!

This replace must be installed by a qualied
(certied or licensed) service person. It has
a sealed gas combustion chamber that uses
a coaxial pipe (pipe within a pipe and having
the same center) venting system. It brings in
fresh air for combustion through the outer pipe
and combustion gases are exhausted through
the inner pipe. If the glass door assembly and
venting pipe are not properly seated, con­nected and sealed, carbon monoxide leakage
(spillage) can occur.

PRODUCT FEATURES

These are a few facts that can help you under­stand and enjoy your direct-vent replace:

• 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 replace may be installed in any room
of your house provided all local codes and
these installation instructions are followed.

• This replace requires a wall switch, hand­held remote or wall thermostat (millivolt) for
operation (see Accessories, page 42).

• This replace does not require electricity
to operate.

• Only the blower requires electricity if in­stalled and if you plan to install the blower at
a later date, do not forget to wire the outlet at
the bottom of the replace when framing.

• A piezo ignitor and ceramic electrode cre­ate spark to ignite the pilot light. It does not
require any matches, batteries or any other
sources of ignition to light the pilot.

• Each time you turn on your replace, you
may notice some amount of condensation
on the inside of the replace glass. This
is normal and will disappear after 10-20
minutes of operation.

• Your dire ct-vent gas fireplace system
(replace and venting) is a balanced and
sealed gas operating unit. It requires ap­proximately 10-20 minutes of operating
time before the ame pattern stabilizes.

• Fireplaces with the sufx of -HA have been
designed to operate at altitudes of 4000
feet and above.

PRE-INSTALLATION PREPARATION

LOCATION AND SPACE
REQUIREMENTS

Determine the safest and most efcient loca­tion for your FMI PRODUCTS, LLC direct-vent
replace. 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 replace and termination cap.

When deciding the location of your replace,
follow these rules:

• Do not connect this replace venting to a
chimney ue serving a separate solid-fuel
burning replace or appliance.

• Due to high temperatures, do not locate this
replace in high trafc areas, windy or drafty
areas or near furniture or draperies.

• Proper clearances must be maintained.

PRE-INSTALLATION PREPARATION

Continued

• If your replace 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 replace. See Figure
3, page 5.

• Your replace is designed to be used in
zero clearance installations. Wall or framing
material can be placed directly against any
exterior surface on the back, sides or top of
your replace, except where standoff spac­ers are integrally attached. If standoff spac­ers are attached to your replace, these
spacers can be placed directly against wall
or framing material. See framing details on
page 7.

• If you plan on installing a television or
enterta in ment center recessed above
your replace, it is recommended that you
maintain a minimum 18" above top of louver
opening.

• When locating termination cap, it is impor­tant to observe the minimum clearances
shown in Figure 7, page 8.

• If recessing into a wall, you can avoid extra
framing by positioning your replace 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 nish.

• 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.

• Do not locate termination cap 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.

• For horizontal installations above 2,000
feet, it is recommended that a 12" extension
pipe be added before starter elbow and a
round horizontal termination be used (see
High Altitude Installation, page 17).

CLEARANCES

Minimum clearances to combustibles for the
replace are as follows:

*Back and sides 0"
Perpendicular walls 6"
Floor 0"
Ceiling to louver opening 42"
Front 36"
Top of Standoffs 0"
Vent (See venting instructions

for specic venting clear-

ances.)
Combustible material with a maximum thick­ness of 5/8" may be ush with the top front
of replace.

* For back and sides of replace, do not pack
with insulation or other materials. 0" clear­ance to combustible materials are for framing
purpose only.

NOTICE: This replace is in­tended for use as supplemental
heat. Use this replace along
with your primary heating sys­tem. Do not install this replace
as your primary heat source.

If you have a central heating

system, you may run system’s

VENTING INSTALLATION

NOTICE: Read these instruc-

tions 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 ue 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 nish
such as vinyl, wood, stucco, etc.

• Never run the vent downward as this may
cause excessive temperatures which could
cause a re.

• 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.

• Snorkel terminations are required when
minimum clearance to grade cannot be
met (see Figure 16 on page 13).

• Have replace and selected vent compo­nents on hand to help determine the exact
measurements when elbowing or offsetting.
Always use wall restops when penetrating
walls and restops when penetrating ceil­ings or attic spaces.

• If using a venting conguration of only
horizontal venting with no vertical run, a
1/4" rise for every 12" of run toward the
termination is required.

• For installation of replace 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: Failure to follow these
instructions will void the war-

ranty.

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 modication 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 replace
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

Horizontal Termination Installation

IMPORTANT: Horizontal square terminations
require only inner portion of wall restop. Hori­zontal installations using round termination
require exterior portion of wall restop (see
Figure 14, page 12).

1. Set replace in its desired location and
determine route your horizontal venting
will take. Do not secure replace until all
venting has been installed. Some instal­lations require sliding replace in and out
of position to make nal venting connec­tions. Figures 14 through 18 on pages 12
through 14 show different congurations
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 replace.

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. Use a 45° elbow to connect venting sys­tem to replace ue collar. The elbow is
designed to be twist-locked onto ue collar
as described in step 2. IMPORTANT: Do
not attempt to alter conguration of elbow
by cutting, twisting, bending, etc.

4. Assemble desired combination of pipe
and elbows to replace ue collar. If there
are long portions of venting run, pre­assembled pipe sections may be installed
as subassemblies for convenience.

VENTING INSTALLATION

Continued

5. Carefully determine location where vent
pipe assembly will penetrate outside
wall. Center of hole should line up with
center line of horizontal vent pipe. Mark
wall for a 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 1/2" hole with zero
clearance is acceptable (see Figure 9).

WARNING: Do not recess

vent termination into any wall.
This will cause a re hazard.

6. Noncombustible Exterior Wall: Position
horizontal vent cap in center of 8 1/2" 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 the outside wall.

Note: Four wood screws provided should

be replaced with appropriate fasteners for
stucco, brick, concrete or other types of
sidings.

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
siding materials. Siding material must be
cut to accommodate standoff. Bolt vent
cap to standoff. Apply non-hardening
mastic around outside edge of standoff.
Position standoff/cap assembly in center

Recommended Applications:

• Installations requiring a vertical rise on building exterior

• Any installation using snorkel termination to achieve one foot above ground

Snorkel terminations are available for installations requiring a vertical rise on the exterior of
the building. If installing snorkel termination below grade, you must provide proper drainage
to prevent water from entering snorkel termination (see Figure 16). Do not back ll around
