or an Exterior Chase
Figure 4 - Corner Installation
WARNING!
To prevent contact with sagging or loose insulation, the fireplace must not be installed against vapor barriers
or exposed insulation. Localized overheating could occur and a fire could result.
These are rough framing dimensions only.
D. PRE-INSTALLATION PREPARATION
1. Fireplace Locations and Space Require ents
This fireplace is intended for installation on an outdoor patio or in your yard. It must never be installed inside of the warm air
envelope of your structure. Significant cold air infiltration will result if it is installed inside of the structure. Figure shows two
typical installations.
Figures 3 and 4 show two typical installations assuming an outside air kit is being used. Therefore, an allowance must be made for
90° bends. Less space is required when ducting goes directly outside without forming elbows.
CLEARANCES!
A minimum 1½ air clearance must be maintained
at the back and sides of the fireplace assembly ex-
cept at the nailing flange where the clearance is ½.
Chimney sections at any level require a 2 minimum
air space clearance between the framing and chim-
ney section.
Note: If the fireplace is a freestanding fireplace, it must
be located a minimum of 10 from a combustible struc-
ture.
A minimum height of 6 4 measured from the base of the
fireplace to the bottom of the termination cap is permit-
ted in this installation.

MONTANA INSTALLATION INSTRUCTIONS
WARNING!
Do not apply combustible finishing materials over any part of the stainless face of this fireplace or a structure fire may
result. The fireplace front may only be covered with noncombustible materials such as ceramic tile, brick or stone. Do not
cover or block any cooling air slots. Do not cover any portion of the opening to the fireplace that would prevent the
installation of an authorized glass door.
Figure 6 - Sidewalls and Surrounds
4. Sidewalls/Surrounds
Adjacent combustible side walls must be
located a minimum of 1  from the
fireplace opening. See Figure 6. If you
are using a decorative surround
constructed of combustible material, it
must be located within the shaded area
defined in Figure 6. Short stub walls are
also acceptable if they are contained
within the shaded area.
CLEARANCES!
A minimum 1½ air clearance must be maintained
at the back and sides of the fireplace assembly ex-
cept at the nailing flange where the clearance is½.
Chimney sections at any level require a 2 minimum
air space clearance between the framing and chim-
ney section.
3. Fra e the Fireplace
Figure 5 shows a typical framing (using x 4 lumber) of the
fireplace, assuming combustible materials are used. All
required clearances to combustibles around the fireplace must
be adhered to. Any framing across the top of the fireplace
must be above the level of the top standoffs.
2. Construct an Outdoor Enclosure
This fireplace is intended to be installed outside the house. It may be installed against the outside wall of the house or as a
freestanding fireplace on your porch, patio, or in your yard.
When installing the outdoor fireplace against an outside wall, it must be enclosed to prevent impact damage to the outside of the
fireplace. Build the outside enclosure out of standard building materials, being careful to maintain the minimum air clearances
specified in these installation instructions.
When installing this fireplace as a freestanding fireplace on your porch, patio or in your yard, it must be enclosed to prevent impact
damage to the fireplace. However, the enclosure must not be finished on all four sides. The exterior of the enclosure may be
finished in a textured plywood, a wood clapboard siding, brick, or a cultured stone. Vinyl siding is not recommended for use on the
front of the fireplace due to the heat the fireplace produces. This can cause the vinyl siding to deteriorate.

Figure 7 - Chimney Offset/Return
Exa ple: Your A dimension from
Figure 7 is 14½. Using Table 1 the
dimension closest to, but not less than
14½ is 145/8 using a 30° offset/return.
It is then determined from the table that
you would need 33 (Dimension B)
between the offset and return. The
chimney components that best fit your
application are two SL111 s.
WARNING!
Do not com-
bine offsets to
create an off-
set greater
than 30° from
vertical. This
may create a
fire hazard
since the natu-
ral draft may
be restricted.

Offset/Returns Table 1
1. Using Offsets and Returns
a. To bypass any overhead obstructions, the chimney may be offset using a 30° offset/return (SL1130). Perform the following
steps to determine the correct chimney component combination for your particular installation.
b. An offset and return may be attached together or a chimney section(s) may be used between an offset and return.
1 Measure how far the chimney needs to be shifted to enable it to avoid the overhead obstacle. See Figure 7, dimension A
to determine chimney sections required to achieve the needed shift.
2 After determining the offset dimension, refer to Table 1 and find the A dimension closest to but not less than the
distance of shift needed for your installation.
3 The B dimension that coincides with the A dimension represents the required vertical clearance that is needed to
complete the offset and return.
4 Read across the chart and find the number of chimney sections required and the model number of those particular
chimney parts.
5 Whenever the chimney penetrates a floor/ceiling, a firestop spacer must be installed.
6 The effective height of the fireplace assembly is measured from the base of fireplace to top of starter collar. See Figure 6.
E. CHIMNEY REQUIREMENTS
When planning your fireplace location, the chimney construction and necessary clearances must be considered. The fireplace system
and chimney components have been tested to provide flexibility in construction. The following figures are the minimum distances from
the base of the fireplace. Minimum overall straight height is 6 4 if the fireplace is freestanding a minimum of 10 from a
combustible structure. See Figure 2, page 8.
1. Minimum overall straight height 14 ft.
2. Minimum height with offset/return 16 ft.
3. Maximum height 90 ft.
4. Maximum chimney length between an offset and return 0 ft.
5. Maximum distance between chimney stabilizers 35 ft.
6. Double offset/return minimum height 4 ft.
7. Maximum unsupported chimney length between the offset and return 6 ft.
8. Maximum straight unsupported chimney height above the fireplace 35 ft.

Table 2
3. Nu ber of Sections Required
To determine the chimney components needed to complete
your particular installation, follow the steps below:
a. Determine the total vertical height of the fireplace
installation. This dimension is measured from the base
of the fireplace assembly to the point where the smoke
exits the termination cap.
b. Subtract the effective height of the fireplace assembly
from the overall height of the fireplace installation
(measured from the base of the fireplace to the bottom
of the termination cap).
c. Refer to Table to determine what components must be
selected to complete the fireplace installation.
d. Determine the number of firestop spacers, stabilizers,
roof flashing, etc. required to complete the fireplace in-
stallation.
2. Chi ney Height Require ents (above roof line)
a. Major building codes specify a minimum chimney height
above the roof top. These specifications are summarized
in what is known as the Ten Foot Rule. This rule states:
If the horizontal distance from the side of the chimney to
the peak of the roof is ten feet or less, the top of the
chimney must be at least two feet above the peak of the
roof, but never less than three feet in overall height above
the highest point where it passes through the roof.
If the horizontal distance from the side of the chimney to
the peak of the roof is more than ten feet, a chimney
height reference point is established on the surface of
the roof a distance of ten feet from the side of the chimney
in a horizontal plane. The top of the chimney must be at
least two feet above this reference point, but never less
than three feet in height above the highest point where it
passes through the roof. See Figure 8.
b. These chimney heights are necessary in the interest of
safety but do not ensure smoke-free operation. Trees,
buildings, adjoining roof lines, adverse wind conditions,
etc. may create a need for a taller chimney should
smoking occur.

F. INSTALLATION OF THE FIREPLACE
WARNING!
Before starting, do the following:
1. Wear gloves and safety glasses for protection.
2. Keep hand tools in good condition. Sharpen cutting edges and make sure tool handles are secure.
3. Always maintain the minimum air space required to the enclosure to prevent fire.
I portant: To ensure proper fit of the glass doors,
check the fireplace opening for square. Measure
diagonal distances of the opening to make sure they
are equal. If they are not equal, continue to shim
the fireplace until those diagonals are equal.
Figure 9 - Positioning the Metal Strips
1. Position the Fireplace
This fireplace may be placed on either a combustible or
noncombustible continuous flat surface. Follow the instructions
for framing on pages 8 and 9. Slide the fireplace into position. Be
sure to provide the minimum air clearance at the sides and
back of the fireplace assembly.
2. Place the Protective Metal Hearth Strips
Included with your fireplace you will find two metal hearth strips
measuring approximately 8 x 4. These strips are used to provide
added protection where the fireplace and the hearth extension
meet.
Slide each metal strip  under the front edge of the fireplace. The
individual pieces must overlap each other by 1 minimum in the
middle of the fireplace to provide continuous coverage of the floor.
See Figure9. These metal strips should extend from the front
and sides of the fireplace opening by .
3. Level the Fireplace
Level the fireplace side-to-side and front-to-back. Shim with
noncombustible material, such as sheet metal, as necessary.
Secure the fireplace (using the nailing flanges located on either
side of the fireplace) to the vertical framing.

MONTANA INSTALLATION INSTRUCTIONS
Figure 11
Installing the Firestop Spacer
CAUTION:
Firestop spacers must be used whenever the
chimney penetrates a ceiling/floor area.
Figure 10
Assembling Chimney
Sections
WARNING!
Carefully follow the instructions for assembly of the
pipe and other parts needed to install this fireplace
system. Failure to do so may result in a fire,
especially if combustibles are too close to the
fireplace or chimney and air spaces are blocked,
preventing the free movement of cooling air.
4. Asse ble Chi ney Sections
Attach either a straight chimney section or an offset to the top
of the fireplace (depending on your installation requirement).
Chimney sections are locked together by pushing downward
until the top section meets the stop bead on the lower section.
The inner flue is placed to the inside of the flue section below
it. The outer casing is placed outside the outer casing of the
chimney section below it. See Figure10.
5. Install Firestop Spacers
Mark and cut out an opening in the ceiling for the firestop
spacer being utilized (17 x 17 for an FS538, 17 x 6 for an
FS540). Frame the opening with the same dimension lumber
used in the ceiling joists.
Install the firestop spacer.
These firestop spacers are designed to provide the minimum
 air space required around the chimney. In all situations,
the firestop spacers are to be nailed to the ceiling joists from
the bottom or fireplace side, EXCEPT when the space above
is an insulated ceiling or attic space. In this situation, the
firestop spacer must be nailed from the top side to prevent
loose insulation from falling into the required  air space
around the chimney. See Figure 11.
All manuals and user guides at all-guides.com

14 4039-150 Rev B 01/04
MONTANA INSTALLATION INSTRUCTIONS
WARNING!
Maintain a minimum of 2 air clearance to all parts of
the chimney system at all times! Failure to maintain
this 2 air clearance will cause a structure fire.
CAUTION:
Inner flue and outer liner sections cannot be disas-
sembled once locked together. Plan ahead to ensure
the proper installation height is achieved with the se-
lected chimney components.
Figure 12 - Installing an Insulation Shield
Note: You must provide support for the pipe during con-
struction and check to be sure inadvertent loading has not
dislodged the chimney section from the fireplace or at any
chimney joint.
WARNING!
When chimney sections exceeding six feet in
length are installed between an offset and re-
turn, structural support must be provided to re-
duce off-center loading and prevent chimney
sections from separating at the chimney joints.
Figure 13 - Offset/Return with Stabilizer
7. Double-check the Chi ney Asse bly
Continue assembling the chimney sections up through the
firestop spacers as needed. While doing so, be aware of the
height and unsupported chimney length limitations that are
given on page 10 under Chimney Requirements.
Check each section by pulling up slightly from the top to ensure
proper engagement before installing the succeeding sections.
If they have been connected correctly, they will not disengage
when tested.
8. Secure the Chi ney Syste
When offsets and returns are joined to straight pipe sections,
they must be locked into position with the screws provided
(outer only), using the predrilled holes. To prevent gravity from
pulling the chimney sections apart, the returns and the
chimney stabilizers have straps for securing these parts to
joists or rafters. See Figure 13.
6. Attic Insulation Shield
An insulation shield should be installed when there is a
possibility of insulation coming into contact with the factory
built chimney system.
a. Bend the tabs at the top of the attic insulation shield
inward. This will help keep the chimney section centered
in the shield.
b. Position the shield over the vertical chimney section
where it penetrates a firestop spacer.
c. Slide the shield down until it rests on the firestop spacer.
The firestop spacer will support the insulation shield. See
Figure 1 .
WARNING! RISK OF FIRE.
Do not fill the space between the chimney sec-
tion and the insulation shield with insulation.

appropriate to the roof pitch and install a round termination
cap following the instructions shipped with the cap.
For chase installations you can use a round termination cap
(TR11), a round telescoping termination cap (TR11T) or a
square termination cap (ST1175). A chase installation must
use a chase top. Chase tops are available from your
Heat-N-Glo distributor.
a. Install the chimney sections up through the chase
enclosure. When using a TR11 round termination cap,
the uppermost top section of pipe must extend 6 above
the top of the chase collar to allow installation of the storm
collar and termination cap. See Figure 14.
b. For installations utilizing a TR11T telescoping round
termination cap, the uppermost chimney section must
be below the top of the chase top, but not more than
14½ below the top of the chase top flashing collar. See
Figure 15.
c. For installations utilizing an ST1175 square termination
cap the last chimney section must not be more than 4½
below the chase top. See Figure 16.

Note: Use only a noncombustible material to finish
the face of the fireplace below the level of the front
standoffs. A noncombustible material such as USG
MICORE CV 30 Mineral Fiber Board, or USG
DUROCK Cement Board is recommended for this
purpose.
Figure 20 - Air Clearance Around Gas Line
12. Co plete the Enclosure
Complete the fireplace enclosure, allowing space for outside
air ducts and gas piping if desired. Electrical wiring should
not come in contact with the fireplace. A minimum clearance
of 1½ must be maintained between the fireplace sides
and the enclosure as well as the fireplace back and the
enclosure. See pages 8 and 9 for framing details.
CAUTION:
When using a gas log set, the fireplace damper
must be set in the fully open position. This en-
sures proper venting of combustion products.
WARNING!
This fireplace was not tested by the fireplace
manufacturer for use with an unvented gas log
heater. To reduce risk of injury, do not install an
unvented gas log heater in this fireplace unless
it has been specifically tested and listed by
Underwriters Laboratories Inc. for use in this
specific model fireplace. Unless the unvented gas
log heater is tested and listed for use in this fac-
tory built fireplace, a fire hazard may be created
that can result in a structure fire.
13. Gas Log/Lighter Provisions
Knockouts are provided on both sides of the fireplace to allow
for connection of a certified gas log lighter or a decorative
gas appliance certified or tested for outdoor use, with a
maximum input of 100,000 BTU/hour, incorporating an
automatic gas shut-off device and complying with the
Standard for Decorative Gas Appliances for Installation
in Vented Fireplaces, ANSI Z21.60. The decorative gas
appliance should be installed in accordance with the National
Fuel Gas Code, ANSI Z223.1-1980. The side refractories are
designed to allow ½ iron pipe to pass through. Use a
noncombustible sealant to seal any opening between the gas
pipe and refractory on the inside. Repack the insulation
removed to seal around the gas pipe where it exits the side of
the fireplace. A minimum 1½ air clearance must be provided
around the ½ iron pipe for a minimum of 4 inches beyond
the fireplace. See Figure 0.
CLEARANCES!
A minimum 1½ air clearance must be maintained
at the back and sides of the fireplace assembly ex-
cept at the nailing flange where the clearance is ½.
Chimney sections at any level require a 2 minimum
air space clearance between the framing and chim-
ney section.

Figure 21 - Factory Built Hearth Extension
Figure 22 - Field Constructed Hearth Extension
WARNING!
Hearth extensions are to be installed only as illustrated to prevent high temperatures from occurring
on concealed combustible materials. Hearth sealing strips prevent burning or hot particles from
inadvertently falling directly on combustible surfaces in the event the building should settle and
disturb the original construction.
14. Hearth Extension
A hearth extension must be installed with all fireplaces to protect the combustible floor in front of the fireplace from both radiant heat
and sparks.
The construction of, and materials used for a hearth extension are shown in Figures 1 and . A hearth extension of this construction
may be covered with any noncombustible decorative material and may have a maximum thickness as per the illustration. Seal
gaps between the hearth extension and the front of the fireplace with a bead of noncombustible sealant.
Field constructed hearth extensions should be constructed in accordance with the instructions in Figure . The field constructed
hearth extension must be constructed from ½ MICORE CV 30, or a material with an equivalent insulation value.

Figure 23 - Position the Hearth Extension
15. Position the Hearth Extension
Position and secure the hearth extension over the protective
metal strips that have been placed partially under the fireplace
front. These strips should be protruding approximately  from
under the fireplace front and  on both sides of the fireplace
opening. Seal the crack between the hearth extension and
fireplace with a bead of noncombustible sealant. See
Figure 3. Apply a noncombustible finishing material of your
choice to the hearth extension.
16. Finishing Material
Do not install combustible materials over the face of the
fireplace! This poses a safety hazard and may start a fire.
You may only use noncombustible material over the face of
the fireplace.
a. Combustible Material
Material which is made of or surfaced with wood,
compressed paper, plant fibers, plastics, or any material
capable of igniting and burning, whether flame proofed
or not, plastered or unplastered.
b. Noncombustible Material
Material which will not ignite and burn. Such materials
are those consisting entirely of steel, iron, brick, tile,
concrete, slate, glass or plasters, or any combination
thereof.
c. Noncombustible Sealant Material
Sealants which will not ignite and burn; General Electric
RTV103 Black (or equivalent), Rutland, Inc. Fireplace
Mortar #63 (or equivalent).
After completing the framing and applying the facing
material (dry wall) over the framing, a ½ wide (maximum)
bead of noncombustible sealant must be used to
close off any gaps at the top and sides between the
fireplace and facing to prevent cold air leaks.
Only noncombustible materials may be used to cover
the metal fireplace front.
17. Mantel
A combustible mantel may be positioned no lower than 1 
above the top of the fireplace opening. See Figure 6, page 9.
The combustible mantel may have a maximum depth of 1 .
Combustible trim pieces that project no more than 1½ from
the face of the fireplace can be placed no closer than 6 from
the top of the fireplace opening. Combustible trim must not
cover the metal surfaces of the fireplace. This mantel
clearance is in accordance with Section 7-3.3.3 of ANSI/
NFPA211.
18. Glass Doors
This fireplace has been tested and listed for use with doors
as specified in Section C, Fireplace System Components.
Please refer to the manual packed with each set of doors for
installation instructions.
19. Chase Top
Construct a chase of desired materials maintaining a minimum
 air space around the chimney.

MONTANA INSTALLATION INSTRUCTIONS
WARNING!
Never install a single wall slip section or smoke-pipe in
a chase structure. The higher temperature of this single
wall pipe may radiate sufficient heat to combustible
chase materials to cause a fire.
WARNING!
Detailed instructions for installation of the chase top, storm collar and termination
cap are packaged with these parts. To avoid danger of fire, all instructions must be
strictly followed, including the provision of air space clearance between chimney
system and enclosure. To protect against the effects of corrosion on those parts
exposed to the weather, we recommend that the chase top and termination cap be
painted with a rust-resistant paint.
