IMPORTANT: Read this owner’s
manual carefully and completely
before trying to assemble, op­erate or service this replace.
Improper use of this replace
can cause serious injury or death
from burns, re, explosions,
electrical shock and carbon
monoxide poisoning.

DANGER: Carbon monoxide

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.

Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning resemble the u,
with headaches, dizziness or nausea. If you
have these signs, the replace may not be
working properly. Get fresh air at once! Have
replace serviced. 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 inu­ence of alcohol and those at high altitudes.

Natural and Propane/LP Gas: Natural and
propane/LP gases are odorless. An odor­making agent is added to the gas. The odor
helps you detect a gas leak. However, the
odor added to the gas can fade. Gas may be
present even though no odor exists.

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 does not require electricity
to operate.

• Only the blower requires electricity if
installed. If you plan to install the blower
at a later date, outlet must be wired at the
bottom of the replace when framing.

• A piezo ignitor and ceramic electrode create
sparks 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.

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.

• 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.

• 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 6.

• If you plan on installing a television or enter­tainment 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 7.

• 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 heat-resistant paint to coordinate
with the exterior nish.

• There must not be any obstruction such

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

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 16).

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 12).

• 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.

www.fmiproducts.com

WARNING: Read all instruc-

tions 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 in-

structions will void the warranty.

NOTICE: Do not seal vent cap
to pipe. Cap must be removable
for service.

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
available only in vent kit HTK (see Figure
14, page 11).

1. Set replace in its desired location and
determine the 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 11 through
13 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 the location of the 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 supported 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.

5. Carefully determine location where vent
pipe assembly will penetrate the outside
wall. The 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 the 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 the 8 1/2"
round hole and attach to exterior wall with
four screws (see Figure 10). Note: The four

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

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
of the 11
exterior wall with wood screws provided
(see Figure 11). Siding standoff must sit
ush against exterior fascia material.

7. Connecting Vent Cap with Horizontal
Vent Pipe: Slide wall restop over vent
pipe before connecting horizontal run to
vent cap (see Figure 12).

Carefully move replace, with vent as-

sembly attached, toward wall and insert
vent pipe into horizontal termination. The
pipe overlap should be a minimum of 1
(see Figure 13, page 11).

INSTALLATION FOR VERTICAL
TERMINATION

Note: Vertical restrictor must be installed in
all vertical installations.

1. Determine route your vertical venting

will take. If ceiling joists, roof rafters or
other framing will obstruct venting system,
consider an offset (see Figure 19) to avoid
cutting load bearing members. Note: 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 in sulat ion. Also note maxim um
vertical rise of venting system and any
maximum horizontal offset limitations.

2. Set replace in desired location. Drop a

plumb line down from ceiling to position
of replace exit ue. Mark center point
where vent will penetrate ceiling. Drill a
small locating hole at this point.

Drop a plumb line from inside of roof to

locating hole in ceiling. Mark center point
where vent will penetrate roof. Drill a small
locating hole at this point.

Flat Ceiling Installation

1. Cut a 11 1/2" square hole in ceiling using locat­ing hole as a center point. Opening should be
framed to 11 1/2" x 11 1/2" inside dimensions,
as shown in Figure 9 on page 9 using framing
lumber the same size as ceiling joists. If area
above the ceiling is an insulated ceiling or an
attic, nail restop from top side. This prevents
loose insulation from falling into required
clearance space. If area above ceiling is a
living space, install restop below framed
hole. Firestop should be installed with no less
than 3 nails per side (see Figure 20).

2. Assemble desired lengths of pipe and
elbows necessary to reach from replace
ue up through restop. Be sure all pipe
and elbow connections are fully twist­locked (see Figure 8, page 9).

3. Cut a hole in roof using locating hole as
a center point. (Cover any exposed open
vent pipes before cutting hole in roof.) The

11 1/2" x 11 1/2" hole must be measured

on the horizontal; actual length may be
larger depending on pitch of roof. There
must be a 1" clearance from vent pipe to
combustible materials. Frame opening as
shown in Figure 9, page 9.

4. Connect a section of pipe and extend up
through hole.

Note: If an offset is needed to avoid

obstructions, you must support vent pipe
every 3 feet. Use wall straps for this pur­pose (see Figure 19). Whenever possible,
use 45° elbows instead of 90° elbows. The

45° elbow offers less restriction to the ow
of ue gases and intake air.

5. Place ashing over pipe section(s) ex­tending through roof. Secure base of
ashing to roof and framing with roong
nails. Be sure roong material overlaps
top edge of ashing as shown in Figure

19. There must be a 1" clearance from
vent pipe to combustible materials.

If area above is an

attic or insulated
area, install restop
above framed hole.

If area above is a

living space, install

restop below framed

hole.
