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.

125078-01B 5

www.fmiproducts.com

• 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 direct ve nt gas fire place 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.

LOCATION AND SpACE
REqUIREMENTS

Determine the safest and most efcient loca­tion for your 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 back, sides or top
of your replace, except where standoff
spacers are integrally attached. If standoff
spacers are attached to your replace,
these s pacer s can be plac ed directly
against wall or framing material. See fram­ing details, page 7.

• 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 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.

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.

• 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.

• For installation of replace at elevations of
4000 feet or greater, pay special attention
to venting requirement recommendations.

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: Do not seal termination

cap to vent pipe. Cap must be
removable for vent inspection
and maintenance.

INSTALLATION pRECAUTIONS

• Wear gl oves an d s afety glasse s f or
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:

• Ins ta llati on of an y d am aged ve nt ing
component

• Unauthorized modication of the venting sys­tem (Do not cut or alter vent components)

• Installation of any component part not
man u fact u red o r app r oved b y FM I

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.

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.

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 and 15 on page 12 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. Assemble desired combination of pipe
and elbows to replace ue 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.
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 pen-

5. Noncombustible Exterior Wall: Position
horizontal vent cap in center of the 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 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
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 the
center of 11 1/2" square hole and attach to
exterior wall with provided wood screws
(see Figure 11). Siding standoff must sit
ush against exterior fascia material.

6. 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-

vent pipe into horizontal termination. Pipe
overlap should be a minimum of 1 1/4" (see
Figure 13, page 13).

Slide wall restop against interior wall

surface and attach with screws provided.
See Figure 13, page 13, for horizontal
termination details.

Place replace into position and shim with

noncombustible material if needed. Nail or
screw side anges to framing to secure
unit in place. IMPORTANT: Make sure re-
place is level before securing. If replace
is not level it will not work properly.
