To determine the safest and most efcient

location for the replace, you must take into

consideration the following guidelines:

1. The location must allow for proper clear-

ances (see Figures 1 and 2, page 4).

2. Consider a location where the heat output

will not be affected by drafts, air condition-

ing ducts, windows or doors.

3. A location that avoids the cutting of

joists or roof rafters will make installation

easier.

4. An outside air kit is included with this re-

place (see Outside Air Kit on page 6).

1. Frame opening for replace using dimen-

sions shown in Figures 1 and 2.

2. The replace may not be installed on

carpeting, tile (other than ceramic) or any

combustible material other than wood

ooring, replace must be installed on a

metal or wood panel extending full width

and depth of replace. (It is acceptable to

cover two outside ends or columns of top

louver panel leaving four center columns

open).

3. Set replace directly in front of this open-

ing and slide unit back until nailing anges

touch side framing.

4. Check level of replace and shim with

sheet metal if necessary.

5. Before securing replace to prepared fram-

ing, metal ember protector (provided) must

be placed between hearth extension (not

supplied) and under bottom front edge of

replace to protect against glowing embers

falling through. If replace is to be installed

on a raised platform, a Z-type ember pro-

tector (not supplied) must be fabricated to

t your required platform height. Ember

protector should extend under replace

a minimum of 1 1/2". The ember protector

should be made of metal material.

6. Using screws or nails, secure replace to

framing through anges located on sides

of replace (see Figure 4).

HEARTH ExTENSION

A hearth extension projecting a minimum of

16" in front of and a minimum of 8" beyond

each side of the replace opening is required

to protect combustible oor construction in

front of the replace. Use an equal material

which meets the following specications: a

layer of noncombustible, inorganic material

having a thermal conductivity of k = .84 BTU

IN/FT2 HR °F (or less) at 1" thick. For example,

if the material selected has a k factor of 0.25,

such as glass ber, the following formula

would apply:

0.25 x 1.0" = 0.30" thickness required

0.84

Thermal conductivity "k" of materials can be

obtained from the manufacturer or supplier of

the noncombustible material. If the hearth ex-

tension is to be covered, use noncombustible

material such as tile, slate, brick, concrete,

metal, glass, marble, stone, etc. Provide

a means to prevent hearth extension from

shifting and seal gap between replace frame

and hearth extension with a noncombustible

material (see Figure 5).

OUTSIDE AIR KIT

Installation of an outside air kit should be

completed during the rough framing of

replace due to nature of its location. The

supplied ex duct measures approximately

10" compressed and up to approximately 36"

extended. Outside combustion air is accessed

through mobile home oor using air kit model

AK6E, included with the replace, or a side

wall using optional air kit model AK6-WE (see

Accessories on page 18).

Installer may choose either left or right side

mounting to allow for proper wall/rafter

clearances.

For AK6-WE Only: Construct a 4.5" x 4.5"

framing or opening on exterior wall (see

Figure 6, page 6).

For AK6E Only: The outside air vent is in-

stalled through a ventilated crawl space (see

Figure 7, page 7).

1. Locate and remove air inlet cover plate on

replace‘s outer surround. Save screws.

2. Cut out any visible insulation that may

obstruct airow.

3. Extend ex duct to attach air inlet tube.

4. Insert inner tab of inlet tube into mating

slot next to opening.

5. Place outer tab of inlet tube over mating

hole next to opening and secure with

screws removed from cover plate in

step 1.

6. Install outside air vent termination in a

location that will not be obstructed by

bushes, snow, etc. Locate vent near the

replace to make ex duct installation

easier.

CHIMNEY PIPE

The chimney system approved for this

replace consists of 12", 18", 24", 36" and

48" snap-lock, double-wall pipe segments,

planned for maximum adaptability to individual

site requirements. Actual lengths gained after

tting overlaps must be taken into consider-

ation (lineal gain) and are given in the lineal

gain chart (see Figure 8). Lineal Gain is the

actual measurable length of a part after two

or more parts are connected.

Each double wall chimney section consists of

a galvanized outer pipe, a stainless steel inner

ue pipe and a wire spacer. Pipe sections must

be assembled independently as chimney is

installed. When connecting chimney directly

to replace, inner ue pipe section must be

installed rst with lanced side up. Outer pipe

section can then be installed over ue pipe

section with hemmed end up. Press down on

each pipe section until lances securely engage

hem on replace starter. The wire spacer will

assure proper spacing between inner and outer

pipe sections.

Continue to assemble chimney sections as

outlined above, making sure that both inner

and outer pipe sections are locked together.

When installing double wall snap-lock chimney

together, it is important to assure that the joint

between chimney sections is locked. Check by

pulling chimney upward after locking. Chimney

will not come apart if properly locked. It is not

necessary to add screws to keep chimney

together (exception, see Figure 14, page 11).

(FST-A)

Adjustable Firestop Thimble Assembly (FST-A)

is used to provide necessary air space and

clearance between chimney pipe and insula-

tion in attic space of a manufactured home.

To install thimble assembly, determine dis-

tance between ceiling joist and roof framing.

Attach adjustable thimble to restop spacer

so that assembly will cover distance. Adjust-

able thimble should be even with or above

rooine. Sheet metal screws or staples may

be used to attach thimble to restop spacer.

An opening large enough to allow insertion

of restop thimble assembly will be required

in ceiling. Attach restop/thimble assembly to

ceiling/ceiling joist using screws or staples as

shown in Figure 9. A minimum of 8 screws or

staples should be used.

Firestop thimble assembly should also be

used where there is a cathedral ceiling, in-

sulation barrier and roof, all in one assembly

in a manufactured home (see Figure 9). The

FST-A thimble can be used in any one of

three common ceiling pitches; at, 1.5"/12'

and 2.5"/12'.

An opening big enough to allow insertion of

restop thimble assembly will be required.

This opening depends on the pitch of your

ceiling. If your ceiling is a at or 1.5"/12'

pitch, you must use adapter plate provided to

seal unwanted openings. For 2.5"/12" pitch,

discard adaptor.

If adapter is needed, secure it onto restop

using holes provided (see Figure 10). The

row of holes on sides of thimble is provided

to allow for pitch variances. Position restop

(top and bottom side) and thimble to desired

angle and secure with screws provided.

Insert thimble and firestop into prepared

opening and secure to ceiling by nailing

through firestop flanges. Thimble should

be even with or above roofline. Thimble

extensions are available (as an option) when

required. See Accessories on page 18.

Note: If there is a second story in the home,

restop spacer 3600FS-8DM will be required.

See Firestop Spacers, page 11.

PENETRATING ROOF

To maintain a 1" clearance to pipe on a roof

with a pitch, a rectangular opening must be

cut.

1. Determine center point through which pipe

will penetrate the roof.

2. Determine center point of the roof. Pitch

is the distance the roof drops over a given

span, usually 12". A 6/12 pitch means that

the roof drops 6" for each 12" measured

horizontally down from roof rafters.

3. Use roof opening chart (Figure 11) to

determine correct opening length and

ashing required.

4. Remove shingles around opening mea-

sured. Cut out this section.

5. Add next sections of pipe until end pen-

etrates roof line. Check to see that proper

clearances are maintained. Extend chim-

ney by adding sections of double wall

pipe until pipe is minimum of 30" above

highest point of roof cutout. Termination

and chimney must extend a minimum of

36" above highest point where it passes

through roof.
