CAUTION:
Do not expose the fireplace to the elements (i.e. rain, etc.) and eep the fireplace dry at all times. Wet insulation
will produce an odor when the fireplace is used.
Safety Precautions
1. Please read these installation instructions completely before beginning installation procedures. Failure to follow
them could cause a fireplace malfunction resulting in serious injury and/or property damage.
2. Always check your local building codes prior to installation. The installation must comply with all local, regional,
state and national codes and regulations.
3. An adequate supply of replacement combustion air from outside the house must be a ailable to the fire for the
fireplace to operate properly. To achie e this, the use of the optional outside air kit is highly recommended.
In the e ent the home is unusually tightly sealed, the optional combustion air kit may not pro ide all the air required
to support combustion. Hearth & Home Technologies is not responsible for any smoking or related problems that
may result from the lack of adequate combustion air. It is the responsibility of the builder/contractor to ensure that
adequate combustion air has been pro ided for the fireplace.
4. The fireplace must be installed with the Hearth & Home Technologies SL Series Chimney System.
The chimney system must always terminate outside the building. Be sure to follow all chimney specifications gi en
in these installation instructions.
5. NEVER lea e children unattended when there is a fire burning in the fireplace.
6. This fireplace is built for solid fuel only. NEVER use gasoline, gasoline type lantern fuel, kerosene, charcoal light
fluid, or similar liquids in this fireplace. Keep any flammable liquids a safe distance from the fireplace.
7. DO NOT use chimney cleaners or flame colorants in your fireplace.
8. The flue damper must be open at all times when the fireplace is in use.
9. While ser icing this fireplace, always shut off any electricity or gas to the fireplace. This will pre ent possible electric
shock or burns. Also, make sure the fireplace is completely cooled before ser icing.
10. To ensure a safe fireplace system and to pre ent the build up of soot and creosote, inspect and clean the fireplace
and chimney prior to use and periodically during the burning season. See Maintenance Instructions in this manual

DESIGN AND INSTALLATION CONSIDERATIONS
When selecting a location for your woodburning fireplace, it is important to e aluate a number of considerations. Modern
construction techniques can create conditions that may not allow your chimney to draft properly. This may result in
smoke spillage from your fireplace, as well as cause other combustion appliances to operate incorrectly.
Tightly sealed construction is important for energy efficiency. Unfortunately, a great deal of effort has been directed to
tightening up sidewall construction, while considerably less attention has been paid to tightening upper portions of the
warm air en elope (insulated ceilings). This has increased the Stack Effect, a condition that increases the negati e
pressure generated by the structure. This negati e pressure will directly affect the drafting performance of a fireplace
chimney. To minimize the negati e pressure generated by stack effect, make certain that all ductwork installed in the attic
spaces is sealed airtight. Minimize the number of recessed light fixtures installed in the insulated ceiling, and use
sealed recessed light fixtures. Finally, make certain the whole house fans and attic access panels are tightly sealed.
These are important design considerations that must be obser ed during the design and construction stage of the
home.
If you desire to put a fireplace in your basement, we recommend that you consider a direct ent gas fireplace. Basements
always ha e a significant negati e air pressure that causes the fireplace system to be more susceptible to smoke
spillage and cold flue backdrafting. Since direct ent gas fireplaces are sealed, they are not affected by the negati e
pressure that exists in basements.
Finally, woodburning fireplaces perform best when their chimney (roof termination) is located on the upper half of the
roof, especially when cathedral ceilings are present. Chimneys that are located on the lower half of the roof realize what
is known as lazy flue and will not draft as well as a chimney that is located in the upper portion of the roof. The reason
for this is that the stack effect generated by the o erall height of the li ing spaces inside the house will exceed the draft
generated by the chimney system. If you desire to place a woodburning fireplace in a location where the termination cap
would be located on the lower half of a roof, such as on an outside wall at the base of a cathedral ceiling, we recommend
that you consider using a direct ent gas fireplace. This will assure the homeowner a fireplace that operates correctly.
These properties do not affect just your woodburning factory-built fireplace. They can cause any woodburning fireplace
as well as any con entionally ented (B- ent) gas appliance to operate improperly. Careful planning at this stage of your
project will ensure satisfaction with the operation of your fireplace once it is completed.

Figure 3 - Installation Along a Wall or an Exterior
Chase
Figure 4 - Corner Installation with Outside Air
WARNING!
Do not draw outside air from garage spaces. Exhaust products of gasoline engines are hazardous.
Do not install outside air ducts such that the air may be drawn from attic spaces, basements or above the
roofing where other heating appliances or fans and chimneys exhaust or utilize air. These precautions will
reduce the possibility of fireplace smo ing or air flow reversal.
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.
Figure 2 - Fireplace Locations
D. PRE-INSTALLATION PREPARATION
Figures 3 and 4 show typical installations. 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
bac and sides of the
fireplace assembly except 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 chimney section.
1. Fireplace Locations and Space Requirements
Se eral options are a ailable to you when choosing a location for your fireplace. This fireplace may be used as a room
di ider, installed along a wall, across a corner or used in an exterior chase. See Figure 2.
Locating the fireplace in a basement, near frequently opened doors, central heat outlets or returns, or other locations
of considerable air mo ement can affect the performance and cause intermittent smoke spillage from the front of the
fireplace. Consideration should be gi en to these factors before deciding on a location.

Figure 5 - Framing the Fireplace
Figure 6 - Sidewalls and Surrounds
2. Frame the Fireplace
The I100 fireplace will fit a framed opening of 615/8 wide x 61 tall. The finished ca ity depth must be no less than
303/8.
Figure 5 shows a typical framing (using 2 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 abo e the top of the standoffs.
3. Sidewalls/Surrounds
Adjacent combustible side walls must be located a minimum of 24 from the fireplace opening. See Figure 6. If you
are using a decorati e 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
bac and sides of the fireplace
assembly except 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 chimney section.
WARNING!
Do not apply combustible finishing materials over any part of the blac face of this fireplace or a structure fire
may result. The blac metal fireplace front may only be covered with noncombustible materials such as ce-
ramic tile, bric , or stone. Do not cover or bloc 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.
Note: The frame of the AED door o erlaps the front of the fireplace beyond the opening by ¾ on each
side and 1½ abo e the top. This should be allowed for when applying facing to the front of the fireplace.

E. CHIMNEY REQUIREMENTS
When planning your fireplace location, the chimney construction and necessary clearances must be considered. The
fireplace system and chimney components ha e been tested to pro ide flexibility in construction. The following figures are
the minimum distances from the base of the fireplace.
1. Minimum o erall straight height 20 ft.
2. Minimum height with offset/return 20.5 ft.
3. Maximum height 90 ft.
4. Maximum chimney length between an offset and return 20 ft.
5. Maximum distance between chimney stabilizers 35 ft.
6. Double offset/return minimum height 24 ft.
7. Maximum unsupported chimney length between the offset and return 6 ft.
8. Maximum straight unsupported chimney height abo e the fireplace 35 ft.
Figure 7 - Chimney Offset/Return
Example: 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° off-
set/return. It is then determined from
the table that you would need 33 (Di-
mension B) between the offset and
return. The chimney components that
best fit your application are two
SL1112s.
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.
1. sing Offsets and Returns
a. To bypass any o erhead 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 a oid the o erhead obstacle. See Figure 7,
dimension A to determine chimney sections required to achie e 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 ertical 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) Whene er the chimney penetrates a floor/ceiling, a firestop spacer must be installed.
6) The effecti e height of the fireplace assembly is measured from the base of fireplace to top of starter collar.
See Figure 6.

Figure 8 - Chimney Height
Table 2
3. Number of Sections Required
To determine the chimney components needed to
complete your particular installation, follow the steps
below:
a. Determine the total ertical 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 effecti e height of the fireplace
assembly from the o erall height of the fireplace
installation (measured from the base of the
fireplace to the bottom of the termination cap).
c. Refer to Table 2 to determine what components
must be selected to complete the fireplace
installation.
d. Determine the number of firestop spacers, stabi-
lizers, roof flashing, etc. required to complete the
fireplace installation.
2. Chimney Height Requirements (above
roof line)
a. Major building codes specify a minimum chimney
height abo e 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
abo e the peak of the roof, but ne er less than
three feet in o erall height abo e 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 abo e this reference point, but
ne er less than three feet in height abo e 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,
ad erse wind conditions, etc. may create a need
for a taller chimney should smoking occur.

Important: 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.
3. Place the Protective Metal Hearth Strips
Included with your fireplace you will find three metal
hearth strips measuring approximately 28 x 4. These
strips are used to pro ide added protection where the
fireplace and the hearth extension meet.
Slide each metal strip 2 under the front edge of the
fireplace. The indi idual pieces must o erlap each
other by 1 minimum in the middle of the fireplace to
pro ide continuous co erage of the floor. See
Figure26. These metal strips should extend from the
front and sides of the fireplace opening by 2.

Le el 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
ertical framing.
2. Install the Outside Air Kit Collar
a. Locate outside air kit on one side of fireplace.
See Figure 23.

ICON I100 INSTALLATION INSTRUCTIONS
CAUTION:
Firestop spacers must be used whenever the
chimney penetrates a ceiling/floor area.
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
bloc ed, preventing the free movement of cool-
ing air.
5. Assemble the Chimney 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27.
6. Install the 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 26 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 pro ide the
minimum 2 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 abo e is an insulated ceiling
or attic space. In this situation, the firestop spacer must
be nailed from the top side to pre ent loose insulation
from falling into the required 2 air space around the
chimney. See Figure 28.

ICON I100 INSTALLATION INSTRUCTIONS
WARNING!
Maintain a minimum of 2 air clearance to all
parts of the chimney system at all times! Fail-
ure to maintain this 2 air clearance will cause
a structure fire.
CAUTION:
Inner flue and outer liner sections cannot be
disassembled once loc ed together. Plan ahead
to ensure the proper installation height is
achieved with the selected chimney
components.
Figure 29 - Installing an Insulation Shield
Note: You must pro ide support for the pipe dur-
ing construction and check to be sure inad ertent
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
reduce off-center loading and prevent chimney
sections from separating at the chimney joints.
Figure 30 - Offset/Return with Sta ilizer
8. Double-check the Chimney Assembly
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 gi en on page 11 under Chimney
Requirements.
Check each section by pulling up slightly from the top
to ensure proper engagement before installing the
succeeding sections. If they ha e been connected
correctly, they will not disengage when tested.
9. Secure the Chimney System
When offsets and returns are joined to straight pipe
sections, they must be locked into position with the
screws pro ided (outer only), using the predrilled holes.
To pre ent gra ity from pulling the chimney sections
apart, the returns and the chimney stabilizers ha e
straps for securing these parts to joists or rafters. See
Figure 30.
7. 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 o er the ertical 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 29.
WARNING! RISK OF FIRE.
Do not fill the space between the chimney sec-
tion and the insulation shield with insulation.

10. Mark the Exit Point of the Roof
Locate the point where the chimney will exit the roof
by plumbing down to the center of the chimney. Dri e
a nail up through the roof to mark the center. See
Figure31.
11. Cut out the Hole in the Roof
Measure to either side of the nail and mark the 17x17
or 17 x 26 opening required. This is measured on the
horizontal; actual length may be larger depending on
the pitch of the roof. Cut out and frame the opening.
See Chapter 25 of the Uniform Building Code for
roof framing details.
Be sure to maintain a 2 minimum air space
between the chimney section and the roof.
12. Assemble the Chimney Sections
Through the Roof
Continue to add chimney sections through the roof
opening, maintaining at least a 2 air space.
13. Install the Roof Flashing
If a roof flashing is to be used, install the roof flashing
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
a ailable from your Heatilator distributor. See the
section titled Constructing a Chase for building a
chase.
14. Install the Outside Air Kit
Outside air kits are supplied as a standard feature
with this fireplace and their use is highly
recommended to minimize the effects of negati e
pressure within the structure. It is recommended to
utilize the shortest duct run to optimize the
performance of the outside air kits. The outside air kit
inlet thimble should be positioned at least four feet
abo e the ground le el, in a manner that will not allow
snow, lea es, etc. to block the inlet.
15. Install the Chimney Air Kit
When installing the chimney air kit, follow the
instructions pro ided with this accessory.
Note: A 3 minimum height difference must be main-
tained from the top of the uppermost chimney sec-
tion to the outside combustion air inlets.
The outside air kits are installed on both sides of the
fireplace. See Figure 32 for handle location/operation.
CAUTION:
The air it handle may get hot while burning
the fireplace. Use care when operating the
handle.
