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 tight, the optional outside air kit may not pro ide 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 pro ided for the fireplace.
The Odyssey Series fireplace is for installation in a room ha ing a olume of at least 3,750 cubic feet.
4. The Odyssey Series fireplace with factory installed gas log set must be installed with the Hearth & Home Technologies SL300 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 factory built to burn natural or propane gas. A gas con ersion kit (to con ert from natural gas to propane or propane to
natural gas) is not a ailable for the Odyssey Series fireplace. The Odyssey must be purchased from the factory as either natural gas or
propane. An optional wood con ersion kit (ODYCKW) is a ailable.
7. NEVER use starter logs, 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.
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 electrical shock or burns.
Also, make sure the fireplace is completely cooled before ser icing.
10. Due to high temperatures, the fireplace should be located out of traffic areas and away from furniture and draperies.
11. Solid fuels cannot be burned in a fireplace where the decorati e gas appliance is installed.
12. In order to install Heatilator® fireplace models ODY42 and ODY42L in the state of Massachusetts, the Commonwealth of Massachusetts
requires the following:
a. The damper must be remo ed.
b. This fireplace is not to be installed for use in a bedroom or bathroom.

ODYSSEY SERIES FIREPLACE WITH GAS LOG SET
DESIGN AND INSTALLATION CONSIDERATION
When selecting a location for your B-Vent appliance, it is important to evaluate a number of considerations. Modern
construction techniques can create conditions that may not allow your vent to draft properly. This may result in spillage
from your B-Vent appliance, 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 B-Vent
appliance vent. To minimize the negative pressure generated by stack effect, make certain that all duct work 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. inally, 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 an appliance in your basement, we recommend that you consider a direct vent gas appliance.
Basements always have a significant negative air pressure that causes the B-Vent system to be more susceptible to
spillage and cold flue back drafting. Since direct vent gas appliances are sealed, they are not affected by the negative
pressure that exists in basements.
inally, a B-Vent appliance performs best when the vent (roof termination) is located on the upper half of the roof,
especially when cathedral ceilings are present. Vents 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 vent 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 vent system. If you desire to place an appliance 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 appliance. This will ensure an appliance that operates correctly.
These properties do not affect just your B-Vent appliance. 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 appliance once it is completed.

D. PRE-INSTALLATION PREPARATION
1. Fireplace Locations an 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 use an exterior chase. The room must have a minimum volume of 3,750
cubic feet. See igure 1.
Figure 1
Fireplace Locations
igures 2 and 3 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.
Figure 3
Installation Along a Wall or an Exterior Chase
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 possi-
bility for smoking or flow reversal.
Figure 2
Corner Installation
CLEARANCES!
A minimum ¾ air clearance must be maintained at the back 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.

ODYSSEY SERIES FIREPLACE WITH GAS LOG SET
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.
2. Frame the Fireplace
igure 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. A 3/4 air clearance must be maintained at the back and sides of the fireplace
assembly. Chimney sections at any level require a two-inch minimum air space clearance between the framing and
chimney section.
Figure 4
Framing the Fireplace
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.
Combustible Materials. Material 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.
Noncombustible Materials. Material which will not ignite and
burn. Such materials are those consisting entirely of steel,
iron, brick, tile, concrete, slate, glass or plasters, or
combination thereof.
Noncombustible Sealant Material. Sealants that will not
ignite and burn; General Electric RTV103 Black) or equivalent,
Rutland, Inc. ireplace Mortar #63 or equivalent.
After completing the framing and applying the facing material
(dry wall) over the framing, a noncombustible sealant, one-
half inch wide maximum, 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.
CLEARANCES!
A minimum ¾ air
clearance must be
maintained at the back
and sides of the fire-
place 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. Hearth Extensions
It is recommended that a hearth extension be installed with all fireplaces. In the event the fireplace is converted to burn
solid (wood) fuel, 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. A hearth extension is required while burning solid fuel.
The construction of, and materials used for a factory built hearth extension are shown in igure 5. A hearth extension of this
construction may be covered with any noncombustible decorative material and may have a maximum thickness of 6. Seal
gaps between the hearth extension and the front of the fireplace with a noncombustible sealant.
Figure 5
Factory Built Hearth Extension
ield constructed hearth extensions should be constructed in accordance with the minimum dimensions provided in
igure 6.
Figure 6 - 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.

4. Si ewalls/Surroun s
Adjacent combustible side walls must be located a minimum of 12 from the fireplace opening. See igure 7. If you are
using a decorative surround constructed of combustible material, it must be located within the shaded area defined in
igure 7. Short stub walls are also acceptable if they are contained within the shaded area. You must maintain adequate
clearances for servicing and proper operation.
Figure 7
Sidewalls/Surrounds
5. Mantel
A combustible mantel may be positioned no lower than 12 above the top of the fireplace opening. The combustible mantel
may have a maximum depth of 12. Combustible trim pieces that project no more than 1-1/2 from the face of the fireplace
can be placed no closer than 6 from the top of the fireplace opening. However, they must not cover the black metal front of
the fireplace. This mantel clearance is an accordance with Section 7-3.3.3 of ANSI/NFPA 211. Combustible trim pieces
can also be located in the shaded areas shown in igure 7.
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 the following flexibility in construction. The following figures are
the minimum distances from the base of the fireplace.
1. Minimum overall straight height 16.5 ft.
2. Minimum height with offset/return 16.5 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 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.
1. Using Offsets an Returns
a. To bypass any overhead obstructions, the chimney may be offset using a 15° offset/return (SL315) or a 30° offset/
return (SL330). 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.
However, the distance between two elbows must never exceed 12 feet in total length.
1 Measure how far the chimney needs to be shifted to enable it to avoid the overhead obstacle. See igure 8,
dimension A.
2 After determining the offset dimension, refer to Table 1 (page 13) and find the A dimension closest to but not
less than the distance of shift needed for your installation.

01/04 31818 Rev J 13
ODYSSEY SERIES FIREPLACE WITH GAS LOG SET
3 The B dimensions that coincide with the A
dimensions represent 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.
WARNING!
Do not combine offsets to create an offset greater
than 30° from vertical. This may create a fire haz-
ard since the natural draft may be restricted.
Figure 8 - Chimney Offset/Return
Table 1 Offset Chart*
6 The effective height of the fireplace assembly is
33. Effective height of fireplace assembly is
measured from base of the fireplace to top of
starter collar. See igure 7.
Example: Your A dimension from igure 8 is 14-1/2.
Using Table 1, the dimension closest to but not less than
14-1/2 is 14-5/8 using the 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 SL312s.
* Proper assembly of air cooled c imney parts result in an overlap at c imney joints of 1-1/4. Effective lengt is built into t is c art.

2. Chimney Height Requirements (Above the 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 oot Rule. This rule states:
If the horizontal distance from the side of the chimney to the peak of the roof is 10 feet or less, the top of the chimney
must be at least 2 feet above the peak of the roof, but never less than 3 feet in overall height above the highest point
where it passes through the roof. See igure 9.
If the horizontal distance from the side of the chimney to the peak of the roof is more than 10 feet, a chimney height
reference point is established on the surface of the roof a distance of 10 feet from the side of the chimney in a
horizontal plane. The top of the chimney must be at least 2 feet above this reference point, but never less than 3 feet
in height above the highest point where it passes through the roof.
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. Determine the Number of Chimney Sections Require
To determine the chimney components needed to complete your particular installation, follow the below steps:
a. Determine the total vertical height of the fireplace installation. This dimension is measured from the base of the
fireplace assembly hearth stone to the point where the smoke exits the termination cap.
b. Subtract the height of the fireplace assembly from the overall height of the fireplace installation.
c. Refer to the chart below 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. STEP-BY-STEP INSTALLATION OF FIREPLACE SYSTEM
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. Position the Fireplace
This fireplace may be placed on either a combustible or
noncombustible continuous surface. ollow the
instructions for framing on pages 9-12. Be sure to provide
the minimum 3/4 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 4 x 26. These strips
are used to provide added protection where the fireplace
and hearth extension meet.
Slide the metal strips two inches under the front edge of
the fireplace. The individual pieces must overlap each
other by one inch in the middle of the fireplace to provide
continuous coverage of the floor. See igure 10. These
metal strips should extend from the front and sides of the
fireplace opening by 2.
3. Level the Fireplace
Level the fireplace side-to-side and front-to-back. Shim
with noncombustible material, such as sheet metal, as
necessary.
Important: To ensure proper fit of the glass doors, check
the fireplace opening to ensure it is square. Measure
diagonal distances of the opening to make sure they are
equal. If they do not equal, continue to shim the fireplace
until those diagonals correspond.
Secure the fireplace by utilizing the nailing flanges located
on either side of the fireplace to the vertical framing.
Figure 10
Positioning the Metal Strips
WARNING!
Carefully follow the instructions for assem-
bly of the pipe and other parts needed to
install this fireplace system. Failure to do
so may result in a fire, especially if com-
bustibles are too close to the fireplace or
chimney and air spaces are blocked pre-
venting the free movement of cooling air.

4. Assembling Chimney Sections
Attach either a straight chimney section or an offset to the
top of the fireplace depending on your installation
requirement. See igure 11. Chimney sections are locked
together by pushing downward until the top section meets
the top head on the lower section. See igure 12. When
using offsets and returns, we recommend the offset and
return sections be secured in place with screws to ensure
proper orientation.
Figure 11
Offset Secured to Fireplace
Note: 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 igure 12.
Figure 12
Connecting Chimney Sections
5. Prepare the Ceiling for Firestop Spacers
Mark and cut out an opening in the ceiling for the particular
firestop spacer being utilized (14-1/2 x 14-1/2 for an
S338, 14-1/2 x 18-3/4 for an S339, or 14-1/2 x 23 for
an S340). rame the opening with the same dimension
lumber used in the ceiling joists.
6. Install the Firestop Spacers
Install the firestop spacer S338 (Straight), S339 (if a
15° offset is located in the ceiling joist area) or S340 (if
a 30° offset is located in the ceiling joist area). Nail the
four sides of the firestop spacer to the joists using a
minimum of three nails per side.
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.
These firestop spacers are designed to provide the
minimum two inch 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 two inch air space
around the chimney. See igure13.
Firestop spacers must be used whenever the chimney
penetrates a ceiling/floor area.
Figure 13
Installing the Firestop Spacer
7. Install an AS8 Attic Insulation Shiel
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. The S338
will support the AS8. See igure14, page 17.
c. Slide the shield down until it rests on the firestop
spacer. The firestop spacer will support the insulation
shield. See igure 14.
When the factory built chimney penetrates an insulated
ceiling at either 15 or 30 degrees from vertical, an
insulation dam should be constructed from plywood of
sheet metal. A minimum 2 air space must be provided
between the insulation dam and the factory built chimney
system.

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 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.
9. Secure the Chimney System
When offsets and returns are joined to straight pipe
sections, they must be locked into position with the
screws provided, 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 igure 15.
Note: Be sure to provide support for the pipe during
construction and check to be sure inadvertent loading
has not dislodged the chimney section from the fire-
place or at any chimney joint.
Figure 15
Offset/Return with Stabilizer
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. Drive a nail
up through the roof to mark the center. See igure 16.
11. Cut out the Hole in the Roof
Measure to either side of the nail and mark the 14-1/2 x
14-1/2 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.
Figure 16
Ceiling and Attic Construction
12. Assemble the Chimney Sections
Continue to add chimney sections through the roof
opening, maintaining at least a 2 air space.
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.
WARNING! RISK OF FIRE.
Do not fill the space between the chimney sec-
tion and the insulation shield with insulation.

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.
or 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 you Heatilator distributor.
See page 19 for building a chase.
14. Install the Chimney Air Kit
When installing a CAK4A chimney air kit, follow the
instructions provided with this accessory. Use of a CAK4A
is required in Canada.
15. Install an Outsi e Combustion Air Kit
The outside air damper assembly is factory installed on
the left hand side of the fireplace assembly. While its use
is optional, it is highly recommended to minimize the
effects of negative pressure within the structure. igure17
illustrates two of many possible methods that can be
used to supply outside air to the fireplace system. To
complete the outside air system, install the outside air
kit according to the installation instructions supplied with
the components. To operate the air kit damper, move the
handle left to open, right to close.
Figure 17 - Outside Air Location
17. Install the Firescreen
Attach the firescreen to the fireplace side, using the two
hairpin clips from the enclosed fastener package. Use
pliers to insert the clip through the last strand of screen
wire and into the hole at the midpoint of the fireplace
side.
18. Install the Glass Doors
If desired, or required by local building codes, install the
glass doors using the instructions supplied with the
particular set of doors you have chosen.
19. Position the Hearth Extension
Position and secure the hearth extension over the
protective metal strips that have been placed partially
under the front of the fireplace. See igure 18. These
strips should be protruding approximately two inches
from under the front of the fireplace. Seal the crack
between the hearth extension and fireplace with a
noncombustible sealant.
20. Applying Finishing Materials on the Hearth
Extension
Apply the noncombustible finishing material of your
choice to the hearth extension. 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. Refer to Page 10 for combustible material
information.
CAUTION:
When using a gas log set, the fireplace damper must
be set in the fully open position. This ensures a proper
venting of combustion products.
Figure 18
Positioning the Hearth Extension
16. Complete the Fireplace 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 ¾ must be maintained between the
fireplace sides and the enclosure as well as the fireplace
back and the enclosure. See Section D for framing details.
Note: The outside air kit can terminate at any level with the
exception that it must terminate at least three feet below
the chimney termination cap as shown in igure 17.

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
igure19.
Figure 19
Chase Constructions
1. Materials for the Chase
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.
In constructing the chase, several factors must be
considered:
a. Maintain a 3/4 minimum air space around the
fireplace.
b. Maintain a 2 air space around the chimney.
c. The chase top must be constructed of a
noncombustible material.
d. In cold climates a firestop spacer should be installed
in an insulated false ceiling at the 8-foot level above
the fireplace assembly. This prevents heat loss
through the fireplace.
e. In cold climates, the walls of the chase should be
insulated to the level of the false ceiling as shown in
igure 20. This will help prevent heat loss from the
home around and through the fireplace.

2. Installing a Termination Cap on a Chase Enclose
Chimney
Construct a chase of desired materials maintaining a
minimum 2 air space around the chimney.
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 instruc-
tions must be strictly followed, including the provi-
sion of air space clearance between chimney sys-
tem 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.
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.
Install the chimney sections up through the chase
enclosure. When using a round termination cap (TR344),
the uppermost top flashing section of pipe must extend
above the top of the chase collar to allow installation of
the storm collar and termination cap.
or installations utilizing a telescoping round termination
cap (TR342), 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
igure21.
or installations utilizing a square termination cap
(ST375), the last chimney section must not be more than
4¾ below the chase top.
When installing a TS345 square termination, the
uppermost chimney section must be no less than 3
below the top of the chase top or more than 2 above the
top of the chase top.
Attach the chase top (CT35) to the top of the chase.
Install the termination cap, using the instructions provided
with it.
Figure 21
Installing a Termination Cap
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 poison-
ing, and to prevent hot combustion gases from con-
tacting and overheating combustible surfaces. Failure
to operate this fireplace with the damper in the open
position may result in asphyxiation or a structure fire.
