CAUTION:
Do not expose the fireplace to the elements (i.e. rain, etc.) and keep 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 fireplace 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 available to the fire
for the fireplace to operate properly. To achieve this,
the use of the optional outside air kit is highly
recommended.
In the event the home is unusually tightly sealed, the
optional combustion air kit may not provide all the air
required to support combustion. Hearth Technologies
Inc. 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 provided for the fireplace.
4. This fireplace must be installed with the Hearth
Technologies Inc. (HTI) SL Series Chimney System.
The chimney system must always terminate outside
the building. Be sure to follow all chimney
specifications given in these installation instructions.
5. NEVER leave children unattended when there is a fire
burning in the fireplace.
6. This woodburning fireplace is built for solid fuel only.
NEVER use gasoline, gasoline type lantern fuel,
kerosene, charcoal lighter 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 servicing this fireplace, always shut off any
electricity or gas to the fireplace. This will prevent
possible electric shock or burns. Also, make sure the
fireplace is completely cooled before servicing.
10. To ensure a safe fireplace system and to prevent the
build up of soot and creosote, inspect and clean the
fireplace and chimney prior to use and periodically
during the burning season. See page 29 for cleaning
instructions.

CL36D AND CR36D INSTALLATION INSTRUCTIONS
DESIGN AND INSTALLATION CONSIDERATIONS
When selecting a location for your woodburning fireplace, it is important to evaluate 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 envelope (insulated ceilings). This has increased the Stack Effect, a condition that increases the negative
pressure generated by the structure. This negative pressure will directly affect the drafting performance of a fireplace
chimney. To minimize the negative 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 observed 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 vent gas fireplace. Basements
always have a significant negative air pressure that causes the fireplace system to be more susceptible to smoke
spillage and cold flue backdrafting. Since direct vent gas fireplaces are sealed, they are not affected by the negative
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 overall height of the living 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 vent 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 conventionally vented (B-vent) 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.

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.
D. PRE-INSTALLATION PREPARATION
1. Fireplace Locations and Space Requirements
Several options are available to you when choosing a location for your fireplace. This fireplace may be used as a
room divider, 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 movement can affect the performance and cause intermittent smoke spillage from the front of
the fireplace. Consideration should be given to these factors before deciding on a location.
CLEARANCES!
A minimum ½ air clearance
must be maintained at the
back and side of the fireplace
assembly.
Chimney sections at any level
require a 2 minimum air
space clearance between the
framing and chimney section.
Figure 2 - Fireplace Locations
Figure 3 shows a 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.
These are rough framing
dimensions only.

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 smoking or air flow reversal.
12538 Rev D 10 02-02

CL36D AND CR36D INSTALLATION INSTRUCTIONS
2. Framing the Fireplace
The CL36D/CR36D fireplace will fit a framed opening of 44 or 365/8 wide (depending on where the outside air is
located) x 42½ tall. The finished cavity depth must be no less than 22½.
Figure 4 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 above the level of the top standoffs. Chimney sections at any level require a 2 minimum air
space clearance between the framing and chimney section.
Figure 4 - Framing the Fireplace
CLEARANCES!
A minimum ½ air clearance must be
maintained at the back and side of the
fireplace assembly.
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 black face of this fireplace or a structure fire
may result. The black metal 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.
02-02 11 12538 Rev D
Page 12
CL36D AND CR36D INSTALLATION INSTRUCTIONS
3. Sidewalls/Surrounds
Adjacent combustible side walls must be located a minimum of 18 from the fireplace opening. See Figure below. If
you are using a decorative surround constructed of combustible material, it must be located within the shaded area
defined below. Short stub walls are also acceptable if they are contained within the shaded area.
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.
1. Minimum overall straight height 14 ft.
2. Minimum height with offset/return 14.5 ft.
3. Maximum height 50 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 20 ft.
7. Maximum unsupported chimney length between the offset and return 6 ft.
8. Maximum straight unsupported chimney height above the fireplace 35 ft.
12538 Rev D 12 02-02
Page 13
CL36D AND CR36D INSTALLATION INSTRUCTIONS
1. Using Offsets and Returns
a. To bypass any overhead obstructions, the chimney may be offset using a 15° (SL315) or a 30° (SL330) offset/
return. 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 5,
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 38½ and is measured from the base of fireplace to top
of starter collar.
WARNING!
Do not combine offsets to create an offset greater than 30° from vertical.
This may create a fire hazard since the natural draft may be restricted.

2. Chimney Height Requirements (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 6.
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.
3. Number 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 (38½) 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 2 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 installation.

F. INSTALLATION OF 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.
1. Positioning the Fireplace
This fireplace may be placed on either a combustible
or noncombustible continuous flat surface. Follow the
instructions for framing on pages 10-12. Slide the
fireplace into position. Be sure to provide the
minimum ½ air clearance at the sides and back of
the fireplace assembly.
2. Placing 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 provide added protection
where the fireplace and the hearth extension meet.
Slide each metal strip 2 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 Figure7.
These metal strips should extend from the front and
sides of the fireplace opening by 2.
3. Leveling 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.
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.
02-02 15 12538 Rev D
Figure 7 - Positioning the Metal Strips
Page 16
4. Assembling 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 Figure8.
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.
CL36D AND CR36D INSTALLATION INSTRUCTIONS
Figure 8
Assembling Chimney
Sections
5. Installing Firestop Spacers
Mark and cut out an opening in the ceiling for the
firestop spacer being utilized (14½ x 14½ for an
FS338, 14½ x 183/8 for an FS339 and 14½ x 23
for an FS340). 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 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 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 2 air space around the chimney. See
Figure 9.
CAUTION:
Firestop spacers must be used whenever the
chimney penetrates a ceiling/floor area.
Figure 9
Installing the Firestop Spacer
12538 Rev D 16 02-02
Page 17
CL36D AND CR36D INSTALLATION INSTRUCTIONS
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. The insulation shield
is installed by positioning it over the vertical chimney
section where it penetrates a firestop spacer. The
firestop spacer will support the insulation shield. See
Figure 10.
Figure 10 - Installing an Attic Insulation Shield
8. Securing the Chimney System
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 11.
Note: You must provide support for the pipe dur-
ing construction and check to be sure inadvertent
loading has not dislodged the chimney section from
the fireplace or at any chimney joint.
7. Double-checking 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 given on page 12 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.
CAUTION:
Inner flue and outer liner sections cannot be disassembled once locked together. Plan ahead to
ensure the proper installation height is achieved
with the selected chimney components.
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.
Figure 11 - Offset/Return with Stabilizer
WARNING!
When chimney sections exceeding six feet in
length are installed between an offset and return, structural support must be provided to reduce off-center loading and prevent chimney
sections from separating at the chimney joints.

9. Marking 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. Drive
a nail up through the roof to mark the center. See
Figure12.
10.Cutting out the Hole in the Roof
Measure to either side of the nail and mark the
14½x14½ 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.
11.Assembling the Chimney Sections
Through the Roof
Continue to add chimney sections through the roof
opening, maintaining at least a 2 air space.
12.Installing 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 (TR344), a round telescoping
termination cap (TR342) or a square termination cap
(ST375/TS345/TS345P). A chase installation must
use a chase top. Chase tops are available from your
Heatilator distributor. See page 22 for building a chase.
Figure 12 - Ceiling/Attic Construction
13.Installing the Outside Air Kit
The outside air kit is supplied as a standard feature
with this fireplace and its use is highly recommended
to minimize the effects of negative pressure within the
structure. It is recommended to utilize the shortest
duct run to optimize the performance of the outside
air kit. The outside air kit inlet thimble should be
positioned at least four feet above the ground level,
in a manner that will not allow snow, leaves, etc. to
block the inlet.
The outside air kit is installed on the left hand side of
the fireplace. Remove the cover plate from the side of
the fireplace assembly where the air kit is to be
installed. See Figure 13 for handle location/operation.

15.Completion of 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 ½ must be maintained
between the fireplace sides and the enclosure as
well as the fireplace back and the enclosure. See
pages 10-12 for framing details.
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 CV230 Mineral Fiber Board, or USG
DUROCK Cement Board is recommended for this
purpose.
CAUTION:
When using a gas log set, the fireplace damper
must be set in the fully open position. This ensures proper venting of combustion products.
16.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 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 14.
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
Underwriters Laboratories Inc. for use in this
specific model fireplace. Unless the unvented
gas log heater is tested and listed for use in
this factory built fireplace, a fire hazard may be
created that can result in a structure fire.

17.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 15 and 16. 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.
Figure 15 - Factory Built Hearth Extension
Field constructed hearth extensions should be constructed in accordance with the instructions in Figure 16. In all
cases, the hearth extension must extend a minimum of 16 to the front and 8 on either side of the fireplace opening.
The field constructed hearth extension must be constructed from ½ MICORE CV230, or a material with an equivalent
insulation value.
Figure 16 - 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.

CL36D AND CR36D INSTALLATION INSTRUCTIONS
18.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 2 from under the fireplace
front and 2 on both sides of the fireplace opening.
Seal the crack between the hearth extension and
fireplace with a bead of noncombustible sealant.
See Figure 17. Apply a noncombustible finishing
material of your choice to the hearth extension.
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 black metal fireplace front.
20.Mantel
A combustible mantel may be positioned no lower
than 41 above the platform or floor the fireplace is
set on. The combustible mantel may have a maximum
depth of 10. See Figure 18. 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
and side of the fireplace opening. Combustible trim
must not cover the black metal surfaces of the
fireplace. This mantel clearance is in accordance with
Section 7-3.3.3 of ANSI/NFPA211.
Figure 17 - Position the Hearth Extension
19.Finishing Material
Do not install combustible materials over the black
face of the fireplace! This poses a safety hazard and
may start a fire. You may only use noncombustible
material over the black 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.

G. CONSTRUCTING A CHASE
A chase is a vertical boxlike enclosure built around the
chimney and fireplace. A chase may be constructed for
the fireplace and chimney or for the chimney only. It is most
commonly constructed on an outside wall.
In cold climates, it is recommended that the chase floor
be insulated using batt type insulation between the floor
joists.
Three examples of chase applications are shown in
Figure 19.
1. Fireplace and chimney enclosed in an exterior
chase.
2. Chimney offset through exterior wall and
enclosed in chase.
3. Chase constructed on roof.
1. Materials
a. The chase is constructed using framing
materials much the same as the walls in your
home. A variety of materials may be used
including brick, stone, veneer brick, or standard
siding materials.
b. In constructing the chase, several factors must
be considered:
1) Maintain a ½ air space around the fireplace.
2) Maintain a 2 air space around the chimney.
3) The chase top must be constructed of
noncombustible material.
4) In cold climates, a firestop spacer should be
installed in an insulated false ceiling at the
8 level above the fireplace assembly. This
reduces heat loss through the chase.
5) In cold climates, the walls of the chase
should be insulated to the level of the false
ceiling as shown in Figure 20. This will help
reduce heat loss from the home around the
fireplace.
Figure 19 - Chase Constructions
Figure 20 - Chase Assembly
12538 Rev D 22 02-02

CL36D AND CR36D INSTALLATION INSTRUCTIONS
2. Chase Top
Construct a chase of desired materials maintaining
a minimum 2 air space around the chimney.
3. Termination Cap
a. Install the chimney sections up through the chase
enclosure. When using a TR344 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 21.
b. For installations utilizing a TR342 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 22.

CL36D AND CR36D INSTALLATION INSTRUCTIONS
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.
c. For installations utilizing an ST375 square
termination cap the last chimney section must
not be more than 4½ below the chase top. See
Figure 24.
d. For installation utilizing a TS345/TS345P Square
Termination Cap, the uppermost chimney section
must not be more than 3 below the chase top.
See Figure 25.
e. Attach the chase top (CT35) to the top of the
chase.
f. Install the termination cap, following the
instructions provided with it.

H. OPERATING INSTRUCTIONS
Note: Save and pass this instruction manual to subsequent home owners. The informa-
tion provided is intended to notify and warn them about making unsafe future modifications
such as the addition of shelves or the use of unauthorized parts and repairs.
1. General Information
This fireplace is intended to operate as a
supplemental heat source for a single room. It is not
designed to function as a primary heat source for a
structure.
Fireplaces, as well as other woodburning appliances,
have been used safely for many years. It has been
our experience that most problems are caused by
improper installation and operation of the fireplace.
Make certain that installation and operation of the
fireplace system is in accordance with these
instructions.
It is extremely important that the fire be supervised
whenever the fireplace is in use. It is also
recommended that an annual inspection be
performed on the fireplace system to determine if the
flue system needs to be cleaned, or as in the case of
any appliance, if minor repairs are required to
maintain the system in top operating condition.
This factory built fireplace is intended for use with either
solid fuel (firewood) or a decorative gas appliance that
has been tested and listed to the Standard for
Decorative Gas Appliances for Installation in
Vented Fireplaces, ANSI Z21.60. When operating
your fireplace, the flue damper must be in the open
position.
This fireplace was not tested and listed for use with an
unvented gas log heater. Do not install an unvented
gas log heater in this fireplace and operate it with the
flue damper in the closed position unless the
unvented gas log heater has been specifically tested
and listed for use in this fireplace by Underwriters
Laboratories Inc.
Use of an unvented gas log heater in this factory
built fireplace may create a fire hazard that can
result in a structure fire.
WARNING!
DO NOT operate this fireplace with the flue
damper in the closed position. Combustion
products must vent up the chimney system to
prevent carbon monoxide poisoning, and to
prevent hot combustion gases from contacting
and overheating combustible surfaces. Failure
to operate this fireplace with the damper in the
open position may result in asphyxiation or a
structure fire.
2. Outside Air
A source of air (oxygen) is required in order for
combustion to take place. Whatever air is consumed
by the fire must be replaced through cracks around
windows, under doors, etc. Most newly constructed
houses or existing homes fitted with tightly sealed
doors and windows are relatively air tight. In this case,
an outside air source must be made available to feed
combustion air from outside the home.
A damper control handle allows the individual control
of the outside air inlet if your fireplace is equipped
with this option. Use of outside air for combustion is
highly recommended to conserve heated air within
the structure and to provide make up air to keep the
fireplace venting properly.
This fireplace will operate correctly only if adequate
ventilation is provided to allow proper draft to the
fireplace system. Hearth Technologies Inc. assumes
no responsibility for the improper performance of the
fireplace system caused by inadequate draft due to
environmental conditions, down drafts, tight sealing
construction of the structure, or mechanical
exhausting devices which create a negative air
pressure within the structure where the fireplace is
located.
CAUTION:
Fireplace operation does require air. Do not take
air from other fuel burning appliances which can
result in improper venting (smoking) or air dilution. Always provide adequate makeup air.
3. Flue Damper
The flue damper must be in a full open position, and
is operated by moving the handle up toward the top
of the fireplace. Before lighting the fire, verify this by
looking up from the inside of the fireplace. Always
operate this fireplace with the damper fully open.
Please note: down drafts, obstructions, damaged or
poor (wet) fuels can cause smoke spillage.
02-02 25 12538 Rev D
Page 26
CL36D AND CR36D INSTALLATION INSTRUCTIONS
WARNING!
Do not store fuel within the clearances to combustibles, or in the space required for refueling
and ash removal. See maintenance instructions,
Clear Space Near the Fireplace.
4. Glass Doors
Most efficient fireplace operation using glass doors
is with the doors open. When the doors are open, the
screen must be closed. Only Hearth Technologies Inc.
glass doors may be used. See Figure 26 for proper
glass door operation.
Figure 26
Proper Operating Positions of Bi-Fold Doors
5. Grate
The factory installed integral grate must be used to
hold the logs from falling out of an open fireplace and
to allow air to pass between the burning logs. It is
important to keep the fire off the hearth and to allow
the ashes to collect beneath the fire, thereby forming
a layer of additional heat protection.
6. Firescreen
A firescreen is always provided to control sparks. It
must be closed whenever the fireplace is in use.
Glass doors or firescreens must not be used to hold
burning material inside the fireplace. Only those glass
door units specifically tested and listed for use with
the specific fireplace model should be used. Screens
should be closed when the glass doors are closed.
CAUTION:
When left closed while burning your fireplace,
firescreens and glass doors will be HOT.
Handle with care!
7. Wood Fuel
FIREWOOD: Your fireplace performance depends on
the quality of the firewood you use. All seasoned wood,
regardless of species, contains about 8,000 BTUs
per pound, and hardwoods have a greater density
than soft woods. A piece of hardwood will contain
about 60% more BTUs than an equal size piece of
soft wood. Firewood is commonly sold by the cord
(128 cu. ft.). A cord of seasoned oak (hardwood) would
contain about 60% more potential energy than a cord
of seasoned pine (soft wood).
Soft woods are generally considered coniferous.
These are trees with needle-like leaves that stay
green all year and carry their seeds exposed in a cone.
Examples of soft wood trees are Douglas fir, pine,
spruce, and cedar. Soft woods require less time to
dry, burn faster and are easier to ignite than
hardwoods.
Hardwoods are generally considered deciduous.
Deciduous trees are broadleaf trees that lose their
leaves in the fall. Their seeds are usually found within
a protective pod or enclosure. Some examples are
oak, maple, apple, and birch. It should be noted that
there are some deciduous trees that are not
considered hardwoods, such as poplar, aspen, and
alder. Hardwoods require more time to season, burn
slower and are usually harder to ignite than soft
woods.
The best wood fuel is a combination of soft wood and
hardwood. Start the fire with soft wood; the fire will
give off quick heat to bring the appliance up to
operating temperature, and then the hardwood can
be added for slow, even heat and longer burn time.
MOISTURE: Regardless of which species of wood you
burn, the single most important factor that effects the
way your fireplace operates is the amount of moisture
in the wood. The majority of the problems fireplace
owners experience are caused by trying to burn wet,
unseasoned wood.
Freshly cut wood can be as much water as it is wood,
having a moisture content of around 50%. Imagine a
wooden bucket that weighs about eight pounds. Fill
it with a gallon of water, put it in the fireplace and try to
burn it. This sounds ridiculous but that is exactly what
you are doing if you burn unseasoned wood.
WARNING!
Burning wet, unseasoned wood can cause excessive creosote accumulation. When ignited
it can cause a chimney fire that may result in a
serious house fire.
12538 Rev D 26 02-02
Page 27
CL36D AND CR36D INSTALLATION INSTRUCTIONS
SEASONING: Seasoned firewood is nothing more
than wood that is cut to size, split and air dried to a
moisture content of around 20%. The time it takes to
season wood varies from around nine months for soft
woods to as long as eighteen months for hardwoods.
The key to seasoning wood is to be sure it has been
split, exposing the wet interior and increasing the
surface area of each piece. A tree that was cut down
a year ago and not split is likely to have almost as
high a moisture content now as it did when it was cut.
The following guideline will ensure properly
seasoned wood:
a. Stack the wood to allow air to circulate freely
around and through the woodpile.
b. Elevate the woodpile off the ground to allow air
circulation underneath.
c. The smaller the pieces, the faster the drying
process. Any piece over six inches in diameter
should be split.
d. Cover the top of the woodpile for protection from
rain and snow. Avoid covering the sides and ends
completely. Doing so may trap moisture from the
ground and impede air circulation.
The problems with burning wet, unseasoned wood
are twofold: First, you will receive less heat output from
wet wood because it requires energy in the form of
heat to evaporate the water trapped inside. This is
wasted energy that should be used for heating your
home. Secondly, this moisture evaporates in the form
of steam which has a cooling effect in your fireplace
and chimney system. When combined with tar and
other organic vapors from burning wood it will form
creosote which condenses in the relatively cool
fireplace and chimney.
8. Starting a Fire
Check the flue damper to be certain it is in the full
open position. Place crumpled or twisted paper under
the fireplace grate. Loosely arrange kindling or small
pieces of wood to form a layer above the paper.
The fires must be built on the fireplace grate, without
danger of the burning fuel falling out of the fireplace
opening.
Light the paper and add small pieces of wood until a
hot bed of embers has been established.
After establishing the fire bed, and the small firewood
is burning briskly, add a minimum of three average
sized pieces of split firewood, place the wood in such
a manner to allow combustion air and flames
between them.
Note: The first three or four fires should be of mod-
erate size to allow the oils and binders to be burned
from the fireplace and the refractory and paint to cure.
You may notice an industrial odor the first few fires.
This is considered normal.
As you use the fireplace, expansion and contraction
will cause minor cracking of the refractory. This is
normal, unavoidable, and will not affect the performance of the fireplace. If the cracks become large
enough that the metal behind the refractory is exposed or large pieces fall out, the panels should
be replaced.
CAUTION:
Never use gasoline, gasoline-type lantern fuel,
kerosene, charcoal lighter fluid, or similar liquids to start or freshen up a fire in this fireplace. Keep all such liquids well away from the
fireplace.
WARNING!
Fireplaces equipped with doors should be operated only with the doors fully open or fully closed.
If doors are left partially open, gas and flame may
be drawn out of the fireplace opening, creating
the risk of both fire and smoke.
9. Draft Problems
Note: When first lighting your fireplace, it may be
necessary to pre-warm the flue to establish a draft.
This is done by holding a rolled up piece of burning
newspaper under the flue damper for a few moments.
This will help reduce smoke spillage during startup.
This fireplace will operate correctly only if adequate
ventilation is provided to allow proper draft to the
fireplace system. Hearth Technologies Inc. assumes
no responsibility for the improper performance of the
fireplace system caused by inadequate draft due to
environmental conditions, down drafts, tight sealing
construction of the structure, or mechanical
exhausting devices which will create a negative air
pressure within the structure where the fireplace is
located.
02-02 27 12538 Rev D
Page 28
CL36D AND CR36D INSTALLATION INSTRUCTIONS
Flue draft is measured as negative pressure in the
chimney. The amount of negative pressure
determines how strong the draft is. The draft is
important because it draws the combustion air into
the fireplace and pulls the smoke out of the chimney.
There are three basic criteria essential in establishing
and maintaining flue draft:
· Availability of combustion air.
· Heat generated from the fire.
· Diameter and height of the flue system.
These three factors work together as a system to
create the flue draft. Increasing or decreasing any one
of them will affect the other two and thus change the
amount of draft in the entire system. See Figure 27.
Figure 27 - Flue Draft
If the fire is hard to start and smoke spills out of the
fireplace, or you find it difficult to establish and
maintain a moderately high burn rate, then the flue
draft is too low and corrective measures must be
taken.
Be sure you have air available for combustion and
that your firewood is dry and well seasoned. Build your
fires properly and according to the instructions given
in operating instructions, Starting a Fire. Be sure your
flue system is installed correctly and that it is the
proper diameter and height. Check for the following:
· All chimney sections are properly installed and
the joints are tightly sealed.
· The chimney is clean and free of creosote
buildup.
· Make sure overhanging trees and branches are
cut back within ten feet of the top of the chimney.
· Ensure the chimney cap is clean and free of any
buildup of soot or creosote.
If you still suspect you have a low draft problem it may
be necessary to increase the volume of air in your
flue system. Since the diameter of your flue system
is matched with the size of the flue collar and should
not be changed, then the height of the system must
be increased. Add chimney sections a little at a time
until the draft improves.
In some cases, regardless of what you do, it can still
be difficult to establish the proper flue draft. This is
especially evident when using an exterior factory built
chimney or exterior masonry chimney. Try placing
several sheets of crumpled paper on top of your
kindling as close to the flue outlet of the fireplace as
possible. Light this paper first then the paper under
the kindling. The heat generated from the rapidly
burning paper on top of the kindling should help get
the draft established.
Still other factors can affect how well your flue system
performs. Neighboring structures, high winds, tall
trees, even hillsides can affect air currents around the
chimney. Well designed chimney caps are available
that can help. Your fireplace dealer is the local expert
in your area. He can usually make suggestions or
discover problems that can be easily corrected
allowing your fireplace to operate correctly as it has
been designed, providing safe and economical heat
for your home.

I. MAINTENANCE INSTRUCTIONS
1. Disposal of Ashes
Ashes should be placed in a metal container with a
tight-fitting lid. The closed container of ashes should
be placed on a noncombustible floor or on the ground,
well away from all combustible materials, pending
final disposal. If the ashes are disposed of by burial
in soil or otherwise locally dispersed, they should be
retained in the closed container until all embers have
thoroughly cooled.
A chimney fire can permanently damage your
chimney system. This damage can only be repaired by replacing the damaged component
parts. Chimney fires are not covered by the Limited Warranty and Buyer Protection Plan.
WARNING!
2. Creosote and Soot
Inspect the chimney internally for obstructions and
construction damage. Flue pipe joints and seams
must be continuous and mechanical tight. In a used
chimney, additional inspection is needed for creosote
buildup, which is the formation of a flammable
sediment.
When wood is burned slowly, it produces tar and other
organic vapors, which combine with expelled
moisture to form creosote. The creosote vapors
condense in the relatively cool chimney flue of a slowburning fire. As a result, creosote residue
accumulates on the flue lining. When ignited, this
creosote makes an extremely hot fire.
The chimney should be inspected at least twice a year
during the heating season to determine if creosote
buildup has occurred.
If creosote has accumulated, it should be removed
to reduce the risk of a chimney fire.
3. Chimney Cleaning
If you do detect a buildup of creosote, contact a
qualified chimney sweep or clean it yourself. To do
this, perform the following steps:
a. Open the damper.
b. Hang a damp sheet across the fireplace opening
to stop dirt and soot from entering the room.
c. Remove the termination cap or housing top.
d. Clean with a stiff nylon brush attached to a pole
OR tie a small burlap bag filled with straw and
several small stones or sand. Work up and down
the flue until the flue is clean.
e. Replace the termination cap or housing top.
4. Clear Space Near the Fireplace
Combustible materials must not be stored on the
hearth extension. Room furnishings such as drapes,
curtains, chairs, or other combustibles must be at
least four feet from the open front of the fireplace.

HEATILATOR WOODBURNING FIREPLACE
LIMITED WARRANTY
As part of its
20-YEAR BUYER PROTECTION PROGRAM
AS PART OF ITS 20 YEAR BUYER PROTECTION PROGRAM (PROGRAM, HEARTH TECHNOLOGIES INC. (HTI) is
pleased to offer a Limited Warranty and a Replacement Parts Advantage covering specific components of your Heatilator woodburning fireplace system ( the Fireplace), installed in the United States of America or Canada. Dealers and employees of HTI
have no authority to make any warranty or authorize any remedies in addition to or inconsistent with the terms of this Program.
Limited Warranty.
HTI warrants the following components of your Heatilator woodburning fireplace to be free from original defects in material and
workmanship during the applicable periods described: five years for the firebox assembly, chimney system and roof termination;
two years for refractory firebox liners; and one year for the grate, wire mesh screens, fan system, outside air system, and glass
doors. All limited warranty periods run from the date of initial installation of your Fireplace (the Installation Date). The Limited
Warranty is subject to the conditions, exclusions and limitations of liability listed below.
Replacement Parts Advantage.
Under HTIs Replacement Parts Advantage, for a period of twenty years from your Installation Date of your Fireplace, if available,
HTI will provide you with repair or replacement parts for defective components which are no longer under their applicable Limited
Warranty, at 50% of the then current retail list price for such components. HTI shall have no responsibility for freight and labor
charges related to such parts.
Conditions, Exclusions, & Limitations of Liability
A. Both the Limited Warranty and Replacement Parts Advantage supplied by HTI apply only while the Fireplace is in its location
of original installation. HTIs obligation under this warranty does not extend to damages resulting from (1) installation,
operation or maintenance of the Fireplace not in accordance with the Installation Instructions, Operating Instructions, and the
Listing Agent Identification Label furnished with the Appliance; (2) installation which does not comply with local building
codes; (3) shipping, improper handling, improper operation, abuse, misuse, accident or unworkmanlike repairs; (4) environmental conditions, inadequate ventilation or drafting caused by tight sealing construction of the structure, air handling devices such as exhaust fans or forced air furnaces, or other causes; (5) use of fuels other than those specified in the
Operating Instructions; (6) installation or use of components not supplied with the Fireplace or any other components not
expressly authorized and approved by HTI; and/or (7) modification of the Fireplace not expressly authorized and approved
by HTI in writing. This warranty is limited to only the component parts manufactured or supplied by HTI.
B. During the first year of the Limited Warranty, HTI will, at its sole option, repair or replace any covered defective component
and will provide replacement parts at no charge. And will pay reasonable labor and freight costs. During the second
through the fifth years of the Limited Warranty (if applicable), HTI will provide replacement parts free of charge for any covered defective component, but will not pay for freight or labor costs related to the shipment of the parts or the actual repair
or replacement. After the fifth anniversary of the Installation date, HTIs sole obligation and your exclusive remedy is set
forth in HTIs Replacement Parts Advantage described above. In no event shall HTI be liable for any incidental or
consequential damages caused by defects in your Fireplace.
C. EXCEPT TO THE EXTENT PROVIDED BY LAW, HTI MAKES NO EXPRESS WARRANTIES OTHER THAN THE WARRANTY
SPECIFIED HEREIN. THE DURATION OF ANY IMPLIED WARRANTY IS LIMITED TO DURATION OF THE WARRANTY SPECIFIED ABOVE.
D. Some states do not allow exclusions or limitations of incidental or consequential damages, so those limitations may not apply
to you. This warranty gives you specific rights; you may also have other rights which vary from state to state.
How to Obtain Service.
To obtain service under this warranty you must:
1. Send written notice of the claimed condition to Heatilator Technical Service Department, Hearth Technologies Inc., 1915 W.
Saunders Street, Mt. Pleasant, Iowa 52641-1563. You may also register your claim online at www.heatilator.com/contact.asp.
2. Provide proof of purchase, model number, serial number, and manufacturing date code to HTI.
3. Provide HTI reasonable opportunity to investigate the claim, including reasonable opportunity to inspect the Appliance prior to
any repair or replacement work and before the Appliance or any component of the Appliance has been removed from the
place of original installation.
4. Obtain HTIs consent to any warranty work before the work is done.
