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, con-

nected 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 un-

derstand 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 nec-

essary 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 se-

lect 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 sys-

tem 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 loca-

tion 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 ma-

terial 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 enter-

tainment center recessed above your re-

place, it is recommended that you maintain

a minimum 18" above top of louver opening.

www.fmiproducts.com

116035-01N6

• When locating termination cap, it is impor-

tant 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 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.

VENTING INSTALLATION

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 sys-

tem (Do not cut or alter vent components)

• Installation of any component part not manufac-

tured 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 serv-

ing a separate solid fuel burning

appliance. Each direct-vent gas

appliance must use a separate

vent system. Do not use com-

mon vent systems.

WARNING: Vent pipe air

space clearances to combus-

tibles 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.

NOTICE: Read these instruc-

tions completely before attempt-

ing 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 at-

tached 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 horizon-

tally 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 com-

bustibles 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.

INSTALLATION PLANNING

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. Hori-

zontal 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 connec-

tions. 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 con-

nections.

Twist-Lock Procedure: Female ends of

pipes have locking lugs (indentations).

These lugs will slide straight into match-

ing 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.

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

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

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.

INSTALLATION FOR VERTICAL

TERMINATION

Note: Vertical restrictor must be installed in

all vertical installations.

1. Determine the route your vertical venting

will take. If ceiling joists, roof rafters or

other framing will obstruct the venting

system, consider an offset (see Figure 26)

to avoid cutting load bearing members.

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 verti-

cal rise of the venting system and any

maximum horizontal offset limitations.

(V)(CD)(CDC)36T Series Only: When

installing the OSR58-30 offset, it must be

turned 20° off center line (see Figure 27,

page 18). This will give you the 1" clear-

ance to horizontal framing members that

are a minimum of 12" above replace.

2. Set replace in desired location. Drop a

plumb line down from ceiling to position

(292 mm x 292 mm) inside dimensions,

as shown in Figure 12 on page 11 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, in-

stall restop below framed hole. Firestop

should be installed with no less than three

nails per side (see Figure 28).

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 11, page 12).

3. Cut a hole in the roof using locating hole as

a center point. (Cover any exposed open

vent pipes before cutting hole in roof.) The

11

1

/

" hole must be measured on

the horizontal; actual length may be larger

depending on pitch of roof. There must

be a 1" clearance from the vent pipe to

combustible materials. Frame opening as

shown in Figure 12, page 12.

4. Connect a section of pipe and extend up

through hole.

VENTING INSTALLATION

Continued

Figure 28 - Installing Firestop

If area above is a living space, install

restop below framed hole.

If area above is an attic or insulated area,

install restop above framed hole.

Note: If an offset is needed to avoid obstruc-

tions, you must support vent pipe every 3

feet. Use wall straps for this purpose (see

Figure 26, page 17). 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) ex-

tending 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

26, page 17. There must be a 1" clearance

from vent pipe to combustible materials.

6. Continue to add pipe sections until height

of vent cap meets the minimum building

code requirements described in Figure 10

on page 9.

Note: You must increase vent height for

steep roof pitches. Nearby trees, adjoining

rooines, steep pitched roofs and other

similar factors may cause poor draft or

down-drafting in high winds. Increasing

vent height may solve this problem.

7. Twist-lock vent cap onto last section of

vent pipe.

Note: If vent pipe passes through any oc-

cupied areas abovethe 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 minimum allowable clearances

to combustibles. Do not ll any required air

spaces with insulation.
