• 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 exces-
sive 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.
VENT TERMINATION CLEARANCES
The nal position of your appliance depends
on the location of the vent termination in rela-
tion to the clearances that must be observed
as shown in Figure 14, page 10.
You may avoid extra framing by positioning
your replace against an already existing
framing member. The back of the replace
may be positioned directly against a com-
bustible wall.
*Check with local codes. In the USA, follow
the current National Fuel Gas Fuel Gas Code,
ANS Z223.1 also known as NFPA 54.

INSTALLATION PLANNING
There are two basic types of direct-vent
installation:
• Horizontal Termination
• Vertical Termination
It is important to select the proper length
of vent pipe for the type of termination you
choose. It is also important to note the wall
thickness.
For Horizontal Termination: Select the
amount of vertical rise desired. The horizontal
run of venting must have 1/4" rise for every
12" of run towards the termination.
WARNING: Never run the
vent downward as this may
You may use one or two 90° elbows in this
vent conguration. See Horizontal Termina-
tion Congurations on page 15.
For Vertical Termination: Measure distance
from replace ue outlet to ceiling. Add ceiling
thickness, vertical rise in an attic or second
story, and allow for sufficient vent height
above roof line. You may use one or two 90°
elbows in this vent conguration. See Vertical
Termination Congurations on page 16.
WARNING: Read all instruc-
Failure to do so could result in
NOTICE:Failure tofollowthese in-
NOTICE: Do not seal termination
INSTALLATION PRECAUTIONS
Consult local building codes before beginning
installation. The installer must make sure to
select the proper vent system for installa-
tion. Before installing vent kit, the installer
must read this replace manual and vent kit
instructions.
Only a qualied service person should install
venting system. The installer must follow
these safety rules:
• Wear gloves and safety glasses for pro-
tection
• 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 com-
ponent
• Unauthorized modication of the venting
system
• Installation of any component part not
manufactured or approved by FMI PROD-
UCTS, LLC
• Installation other than as instructed by
these instructions
www.fmiproducts.com 56131J12
VENTING INSTALLATION
Continued
Note: You may use two 45° elbows in place of
a 90° elbow. You must follow rise to run ratios
when using 45° elbows.
For two-story applications, firestops are
required at each oor level. If an offset is
needed in the attic, additional pipe and elbows
will be required.
You may use a chase with a vent termination
with exposed pipe on exterior of house. See
Installing Vent System in a Chase.
Your FMI PRODUCTS, LLC direct-vent
replace has been tested for a minimum 3'
rise with a maximum 11" wall thickness. Any
horizontal application longer than 12" must
provide a minimum of 1 foot of vertical rise for
every 3 feet of horizontal run. The maximum
horizontal run is 20' with 8' vertical rise (see
Installation for Horizontal Termination). The
maximum vertical run is 30' (see Installation
for Vertical Termination, page 16).
A chase is a vertical box-like structure built to
enclose venting that runs along the outside
of a building.
and construction of the chase
-
Note: When installing in a chase, you should
insulate the chase as you would the outside
walls of your home. This is especially im-
portant in cold climates. Minimum clearance
between vent pipes and combustible materials
such as insulation is 1".
After framing chase (see Framing on page
7) install vent system by following installation
instructions.
INSTALLATION FOR HORIZONTAL
TERMINATION
1. Determine the route your horizontal vent-
ing will take. Note: The location of horizon-
tal vent termination on exterior wall must
meet all local and national building codes
and must not be blocked or obstructed.

Snorkel terminations are available for
terminations requiring a vertical rise on
the exterior of building (see Figures 15
and 16). Snorkel kits are available for
rigid pipe applications only to provide a
14" rise and a 36" rise (see page 19).
Follow the same installation procedures
used for standard horizontal terminations.
If installing snorkel termination to raise
vent termination from below grade level
such as in a basement installation, you
must provide proper drainage to prevent
water from entering snorkel termination
(see Figure 16). Do not back ll around
snorkel termination.

2. Rigid vent pipes and ttings have special
twist-lock connections. Assemble desired
combination of pipe and elbows to appli-
ance adaptor with pipe seams oriented
towards wall or oor.
Twist-lock Procedure: Female ends
of pipes and ttings have four locking
lugs (indentations). These lugs will slide
straight into matching slots on male ends
of adjacent pipes and ttings. Push pipe
sections together and twist one section
clockwise approximately one-quarter turn
until sections are fully locked. See Figure
17. Note: Horizontal runs of vent must
be supported every three feet. Use wall
straps for this purpose.
3. Attach vent pipe assembly to replace us-
ing twist lock connections for rigid pipe or
clamp method for ex pipe. Set replace
in front of its permanent location to insure
minimum clearances. Mark wall for a 10 3/4"
square hole (for noncombustible material
such as masonry block or concrete, a 8 1/2"
diameter hole is acceptable). See Figure
18. The center of hole should line up with
center line of rigid vent pipe. Cut a 10 3/4"
x 10 3/4" square hole through combustible
exterior wall (8 1/2" diameter hole if non-
combustible). Frame as necessary.

4. Three types of vent caps are available
for horizontal terminations. Two square
terminals are available; one for rigid pipe
applications and one for ex pipe ap-
plications. A round vent termination with
a slip t connection is also provided for
rigid pipe applications to be used when
a wall thickness or off spacing must be
accommodated. Each may be purchased
as a kit that includes a 45° elbow and a
restop that accommodates a square or
round termination (see Parts List for Vent-
ing Kits and Components, page 19).
Apply a
bead of non-hardening mastic around out-
side edge of vent cap. Position vent cap
in center of the 8 1/2" hole on the exterior
wall with arrow on vent cap pointing up.
Attach vent cap with four wood screws
provided (see Figure 19). Note: Replace
wood screws with appropriate fasteners
for stucco, brick, concrete, or other types
of siding.

standoff must be installed between vent
cap and exterior wall. Siding standoff
prevents excessive heat from damaging
siding materials. Siding materials 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 square hole and attach to exte-
rior wall with wood screws provided (see
Figure 20). Siding standoff must sit ush
against exterior fascia material.
5.
Slide wall restop over vent
pipe before connecting horizontal run to
vent cap (see Figure 21).
6. Make nal connection to vent terminal.
Flush or recessed with short vent sys-
tem: Vent system may be pre-sized. Check
for nal t and slide unit into framing with
restop in place. This is helpful when using
rigid pipe and round vent termination. Vent
may be preconnected and slipped through
restop. Make sure 45° connection at unit
is tight and does not come loose before
unit is nailed to framing.
Vent pipe must be manipulated at outer
end to make nal connection. Manually
secure pipe inside open framing. If this
is a retrot installation in an inaccessible
space, you may have to secure outer
end of vent pipe with wall straps and tap
screws at outer end.
When using tap screws with rigid pipe,
be sure that screws do not penetrate
inner pipe. These procedures may also
be followed by exible pipe installations.
To use exible pipe, vent must be drawn
through end restop, cut back to 6"-8" to
permit easy connection of ex termination
and connection must be slipped back into
and secured to installation. You must use
an adequate number of spring spacers at
ends and closest bend to termination to
prevent kinks or collapsing on the re. Do
not use screws with ex pipe. Vent system
must be code inspected and released
before adding dry wall or other surface
treatments.

INSTALLATION FOR VERTICAL
TERMINATION
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 24) to avoid
cutting load bearing members.

Figures 22 and 23 show different congura-
tions for venting with horizontal termination.
Each figure includes a chart with vertical
minimum/maximum and horizontal maximum
dimensions which must be met. All horizon-
tal terminations require 1/4" rise per 12" of
horizontal run. You must add 1/4" of vertical
height (V) in the following tables for each foot
of horizontal run (H).

Figure 26 - Installing Firestop
If area above is a living space, install
restop below framed hole.
If area above is an attic, install restop
above framed hole.
Note: Pay special attention to these instal-
lation instructions for required clearances
(air space) to combustibles when passing
through ceilings, walls, roofs, enclosures,
attic rafters, etc. Do not pack air spaces
with insulation. Also note maximum
vertical rise of venting system and any
maximum horizontal offset limitations.
Offsets must fall within parameters shown
in Figure 25.
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.
1. Cut a 12 1/2" square hole in the ceiling us-
ing locating hole as a center point. Open-
ing should be framed to 12 1/2" x 12 1/2"
inside dimensions, as shown in Figure
18 on page 13, using framing lumber the
same size as ceiling joists. If area above
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. The restop should be installed with
no less than three nails per side (see
Figure 26).
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 twist-
locked (see Figure 17, page 13).
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
12 1/2" x 12 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 18 on page 13.

4. Connect a section of pipe and extend
up through hole. If an offset is needed to
avoid obstructions, you must support vent
pipe every 3 feet. Use wall straps for this
purpose (see Figure 24, page 15). When-
ever 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) ex-
tending through roof. Apply a bead of
silicone or roof sealer to the bottom ange
of ashing and secure base of ashing
to roof and framing with roong nails. Be
sure roong material overlaps top edge of
ashing as shown in Figure 24, page 15.
There must be a 1" clearance from vent
pipe to combustible materials.
6. Continue to add pipe sections until the
height of vent cap meets the minimum
building code requirements described in
Figure 14, page 10.
Note: You must increase vent height for
steep roof pitches. Nearby trees, adjoining
rooines, steep pitched roofs, and other
similar factors may cause poor draft or
down-draft condition (see Figure 24, page
15). Increasing vent height may solve this
problem.
7. Apply a bead of sealer to the upper edge
of ashing collar. Slide storm collar over
pipe and down to top edge of ashing.
Apply a second bead of silicone or roof
sealer around remaining seam of storm
collar. Twist-lock vent cap onto last section
of vent pipe. Finish sealing ange around
roong material with roong sealer.
Note: If vent pipe passes through any oc-
cupied areas above the rst oor, including
storage spaces and closets, you must enclose
pipe. You may frame and sheetrock enclosure
with standard construction material. Make
sure and meet the minimum allowable clear-
ances to combustibles. Do not ll any required
air spaces with insulation.

support box on roof sheathing using the
locating hole as a center point.
2. Cut hole 1/8" larger than the support box
outline (see Figure 27).
3. Lower support box through hole in roof
until bottom of box extends at least 2"
below ceiling (see Figure 27). Align sup-
port box vertically and horizontally using
a level. Temporarily tack support box in
place through inside walls and into roof
sheathing.
4. Using tin snips, cut support box from top
corners down to rooine and fold result-
ing aps over roof sheathing (see Figure
28). Apply a bead of non-hardening mas-
tic around top edges of support box to
make a seal between box and roof. Nail
in place with roong nails. Remove any
combustible material that might be inside
of support box.

HIGH ALTITUDE INSTALLATION
Your FMI PRODUCTS, LLC direct-vent
replace has been tested and approved for
elevations from 0-2,000 feet (USA).
Fireplaces for High Altitude (models ending
in -HA) are for installation above 4,000 feet
only. These replaces are equipped with parts
specic for higher altitudes. IMPORTANT:
These replaces can NOT be converted to
propane/LP gas.
When installing a non-high altitude replace at
an elevation above 2,000 feet (USA), you may
need to decrease the input rating by changing
the existing burner orice to a smaller size.
Reduce input 4% for each 1,000 feet above
sea level. Check with your local gas company
for proper orice size identication.
