This fireplace complies with the National
Safety Standards and is listed and tested by
PFS Corporation to ANSI Z21.50/CSA 2.22

standard as vented gas replace.

NOTICE: Decorative product not
for use as a heating appliance.

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

PRODUCT FEATURES

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

• The CD36R dedicated rear vent is best suited
for ush or corner installations when vented
horizontally through an exterior wall.

• The CD36T dedicated top vent is suited

for any application where height is nec­essary to terminate the venting system

either through the roof (vertical) or to gain
sufcient height and offset to vent to an
outside/exterior wall (horizontal).

• The vent pipe installation is very important
to allow for proper operation. You must se­lect the appropriate unit for your application
and follow the venting instructions to plan
your installation.

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

• Models (V)(CD)(CDC)36R/T are equipped

with a millivolt gas control system that does

not require electricity to operate. A piezo
ignitor is provided to light the pilot without
using matches or lighters.

• Models (V)(CD)(CDC)36RE/TE are
equipped with an electronic ignition sys­tem that requires 120VAC to operate. An
electrode ignitor automatically lights the
pilot ame when the replace is turned on.

• All models can accept an optional circulat-

ing air blower when 120 VAC connection

is supplied. If you plan to install an optional
blower, do not forget to wire the replace
outlet when framing.

• 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-vent gas fireplace system
(replace and venting) is a balanced and
sealed gas operating unit. It is highly efcient
because it uses outside air for combustion

while independently heating the indoor air.

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 com-

mon 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, page 6.

• 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 spac-

ers are integrally attached. If standoff spac-

ers 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 enter­tainment center recessed above your re­place, it is recommended that you maintain
a minimum 18" above top of louver opening.

PRE-INSTALLATION PREPARATION

Continued

• 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 (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.

REQUIREMENTS FOR THE COMMONWEALTH OF

MASSACHUSETTS

For all side wall horizontally vented gas fueled
equipment installed in every dwelling, building or
structure used in whole or in part for residential
purposes, including those owned or operated by

the Commonwealth and where the side wall ex-

haust vent termination is less than seven (7) feet
above nished grade in the area of the venting,
including but not limited to decks and porches,
the following requirements shall be satised:

INSTALLATION OF CARBON

MONOXIDE DETECTORS

At the time of installation of the side wall horizon­tal vented gas fueled equipment, the installing
plumber or gastter shall observe that a hard

wired carbon monoxide detector with an alarm

and battery backup is installed on the oor level
where the gas equipment is to be installed. In
addition, the installing plumber or gastter shall

observe that a battery operated or hard wired car­bon monoxide detector with an alarm is installed

on each additional level of the dwelling, building or
structure served by the side wall horizontal vented
gas fueled equipment. It shall be the responsibility
of the property owner to secure the services of
qualied licensed professionals for the installation

of hard wired carbon monoxide detectors.

In the event that the side wall horizontally
vented gas fueled equipment is installed

in a crawl space or an attic, the hard wired
carbon monoxide detector with alarm and

battery back-up may be installed on the next
adjacent oor level.

In the event that the requirements of this
subdivision can not be met at the time of

completion of installation, the owner shall

have a period of thirty (30) days to comply with
the above requirements; provided, however,
that during said thirty (30) day period, a battery

operated carbon monoxide detector with an

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:

• 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" clear-

ance 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 compo-

nents on hand to help determine the exact

measurements when elbowing or offsetting.
Always use wall restops when penetrating
walls and restops when penetrating ceil-

ings 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.

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.

IMPORTANT: Do not seal vent cap to pipe.

Cap must be removable for servicing.

NOTICE: Failure to follow these in-

structions will void the warranty.

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 compo-

nent

• 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 20, page 15).

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 instal-

lations require sliding replace in and out
of position to make nal venting connec­tions. Figures 18 through 25 on pages 14
through 17 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 one-

quarter turn until sections are fully locked
(see Figure 11).

Note: Horizontal runs of vent must be sup-

ported every three feet. Use wall straps
for this purpose.

3. Any straight pipe section, a 45° or 90°

elbow can be used when rst connecting
the venting system to replace. Elbows
are designed to twist-lock into any of four

90° positions to direct the venting system
to the desired location. IMPORTANT: Do

not attempt to alter the 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, preas-

sembled 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 accept-

able (see Figure 12).

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 outside wall.

Note: Four wood screws provided should

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

sidings (see Figure 13).

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 1/2" square hole and attach to
exterior wall with wood screws provided

(see Figure 14). Siding standoff must sit
ush against exterior fascia material.

7. Connecting Vent Cap with Horizontal
Vent Pipe: Fit outer and inner wall restop

into wall before connecting horizontal run
to vent cap (see Figure 15).

Carefully move replace, with vent assem-

bly attached, toward wall and insert vent

pipe into horizontal termination. The pipe
overlap should be a minimum of 1 1/4".

Slide wall restop against interior wall sur-

face and attach with screws provided (see

Figure 16, page 14). See Figure 17, page
14, 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.
