SAFETY Continued
Overfiring of a fireplace is a condition where excessive
temperaturesarereached,beyondthedesigncapabilities
of theappliance. Thedamagethatoccurs fromoverfiring
isnotcoveredunderthemanufacturer’slimitedwarranty.
WARNING: CONTINUED OVERFIRING CAN PER-
MANENTLY DAMAGE YOUR FIREPLACE SYSTEM.
SOME EXAMPLES OF CONDITIONS THAT COULD
CAUSE OVERFIRING ARE:
• BURNINGQUANTITIESOFSCRAPLUMBER,PINEBRANCH-
ES, PAPER OR CARDBOARD BOXES WHICH EXCEED THE
VOLUME OF THE NORMAL LOG FIRE.
• BURNING TRASH, CHEMICALS OR CHEMICALLY TREATED
COMBUSTIBLES.
Disposal of Ashes
Ashes should be placed in a metal container with a tight-
fittinglid. Theclosed containerof ashesshould beplaced
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 cinders have thoroughly cooled.
WHEN USING THE DECORATIVE APPLIANCE, THE
FIREPLACE DAMPER MUST BE SET IN THE FULLY
OPEN POSITION.
Never use gasoline, gasoline-type lantern fuel, kero-
sene, 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 while it is in use.
Use SOLID WOOD only for fuel. It is best to use dry
and well seasoned hardwood. Softwoods tend to burn
veryquickly.DONOTusetreatedwood,charcoal,coal,
trash, driftwood or woods that have been dipped in
tar,pitch,pinetar,creosote,etc.Woodproductsmade
with synthetic binders, such as plywood, produce ab-
normally high temperatures and sputtering, smoking
fires. When burning artificial logs, please read and
follow the instructions provided by the manufacturer.
Never burn treated construction lumber or scraps.
These woods burn excessively hot and may contain
chemicals used to treat insects and fungus. When
burned,thesechemicalscanposeasignificanthazard.
IMPORTANT: See appendix A, page 27 for additional
information regarding draft requirements, smoking
causes and troubleshooting.
WARNING:BURNINGIMPROPERFUEL (I.E.CHAR-
COAL) CAN RESULT IN CARBON MONOXIDE POISON-
ING, WHICH MAY LEAD TO DEATH!
Carbon Monoxide Poisoning – Early signs of carbon
monoxidepoisoningresemblethefluwithheadaches,
dizziness, or nausea. If you have these signs, get
fresh air at once! Have the appliance inspected by a
qualifiedservicetechnician. Somepeoplearemoreaf-
fectedbycarbonmonoxidethanothers. Theseinclude
pregnant women, people with heart or lung disease
or anemia, those under the influence of alcohol, and
those at high altitudes.
Ventilation Requirements - Provide adequate air for
combustion. The fresh air requirements of this ap-
pliance must be met within the space where it will
be installed.
Smoke Detectors - Since there are always several
potential sources of fire in any home, we recommend
installing smoke detectors. If possible, install the
smoke detector in a hallway adjacent to the room (to
reduce the possibility of occasional false activation
from the heat produced by the appliance). If your local
coderequires a smoke detector be installed within the
same room, you must follow the requirements of your
local code. Check with your local building department
for requirements in your area.
Creosote – Formation and Need for Removal
When wood is burned slowly, it produces tar and other
organic vapors, which combine with expelled mois-
ture to form creosote. The creosote vapors condense
in the relatively cool chimney flue of a slow-burning
fire. As a result, creosote residue accumulates on
the flue lining. When ignited this creosote makes an
extremely hot fire.
The chimney shall be inspected at least twice a year
duringtheheatingseasontodeterminewhenacreosote
builduphasoccurred. Whencreosotehasaccumulated
(1/8" [3 mm] or more) it shall be removed to reduce
the risk of a chimney fire.
WARNING: Children and adults should be alerted
to the hazards of high surface temperatures and to
stay away to avoid burns or clothing ignition. Young
children should be carefully supervised when in the
same room as fireplace.

FIREPLACE INSTALLATION
SELECTING LOCATION
To determine the safest and most efficient location for the fireplace,
you must take into consideration the following guidelines:
1. The location must allow for proper clearances (see Figures 4 and
5).
2. Consider a location where fireplace will not be affected by drafts,
air conditioning ducts, windows or doors.
3. A location that avoids cutting of joists or roof rafters will make
installation easier.
4. An outside air kit is available with this fireplace (see Optional
Outside Air Kit on page 9).
MINIMUM CLEARANCE TO COMBUSTIBLES
Back and sides of fireplace 1-1/2" (39 mm) min.
Ceiling 42" (1067 mm) min.

Mantel clearances see Mantels, page 8
Chimney outer pipe surface 2" (51 mm) min.
* Not required at nailing flanges
** See step 2 of Framing
WARNING: Do not pack required air spaces with
insulation or other materials.
Minimum/Maximum Chimney Height for Residential Installation
Minimum height of chimney, measured from base of fireplace to flue
gas outlet of termination, is 16 feet for straight flue or a flue with one
elbow set. Maximum distance between elbows is 6 feet. For systems
with two elbow sets, minimum height is 22 feet. Maximum height of
any system is 50 feet. This measurement includes fireplace, chimney
sections and height of termination assembly at level of the flue gas
outlet (see Figure 15, page 12).
FRAMING
1. Frame opening for fireplace using dimensions shown in Figures 4
and 5.
2. If fireplace is to be installed directly on carpeting, tile or any
combustible material other than wood flooring, fireplace must
be installed upon a metal or wood panel extending full width and
depth of fireplace.
3. Set fireplace directly in front of this opening and slide unit back
until nailing flanges touch side framing.
4. Check level of the fireplace and shim with sheet metal if necessary.
5. Before securing fireplace to prepared framing, ember protector
(provided) must be placed between hearth extension (not sup-
plied) and under bottom front edge of fireplace to protect against
glowing embers falling through. If fireplace is to be installed on a
raised platform, a Z-type ember protector (not supplied) must be
fabricated to fit your required platform height. Ember protector
should extend under fireplace a minimum of 1 1/2". Ember protector
should be made of galvanized sheet metal (28 gauge minimum to
prevent corrosion.
6. Using screws or nails, secure fireplace to framing through flanges
located on sides of fireplace.

FIREPLACE INSTALLATION Continued
HEARTH EXTENSION
A hearth extension projecting a minimum of 20" in front of and a
minimum of 12" beyond each side of fireplace opening is required
to protect combustible floor construction in front of fireplace. Fabri-
cate a hearth extension using a material which meets the following
specifications: a layer of noncombustible, inorganic material having a
thermal conductivity of k=0.84 BTU IN/FT, HR. F (or less) at 1" thick.
For example, if the material selected has a k factor of 0.25, such as
glass fiber, the following formula would apply:
0.25 x 1.0" = 0.30" thickness required
0.84
Thermal conductivity "k" of materials can be obtained from manufac-
turer or supplier of noncombustible material. If hearth extension is
to be covered, use noncombustible material such as tile, slate, brick,
concrete, metal, glass, marble, stone, etc. Provide a means to prevent
hearth extension from shifting and seal gap between fireplace frame
and hearth extension with a noncombustible material (see Figure 6).
WARNING: Hearth extension is to be installed only
as shown in Figure 6.

MANTELS
A mantel may be installed if desired (see Figure 7). Woodwork such as
wood trims, mantels or any other combustible material projecting from
front face must not be placed within 12" (36" Models) or 18" (42/50"
Models) of fireplace opening. Combustible materials above 12" (36"
Models) or 18" (42/50" Models) and projecting more than 1 1/2" from
fireplace must not be placed less than 15" (36" Models) or 21" (42/50"

VENTING INSTALLATION
OPTIONAL OUTSIDE AIR KIT (MODEL AK4/AK4F)
The installation of an outside air kit should be performed during
the rough framing of the fireplace due to the nature of it's location.
Outside combustion air is accessed through a vented crawl space
(AK4F) or through a sidewall (AK4).
CAUTION: Combustion air inlet ducts shall not
terminate in attic space.
The maximum height for the air vent can not exceed
3 feet below the flue gas outlet of the termination.
Figure 8 - Outside Air Kit
CHIMNEY PIPE
WARNING: Label part number 900599-01 must
be applied by the installer to all chimney pipe
sections but is not required on sections that will
be visible after the installation is complete. Label
must wrap around the circumference of the pipe.
See accessories, page 25 for Kit F2659.
The IHP chimney system consists of 12", 18", 24", 36" and 48" snap-
lock, double-wall pipe segments, planned for maximum adaptability
to individual site requirements. Actual lengths gained after fitting
overlaps must be taken into consideration (lineal gain) and are
given in the lineal gain chart (see Figure 9). Lineal Gain is the actual
measurable length of a part after two or more parts are connected.
For Canada, use chimney parts designated "HT".
WARNING: The opening in the collar around the
chimney at the top of the fireplace must not be ob-
structed.Neveruseblowninsulationtofillthechimney
enclosure.
Figure 9 - Lineal Gain
ASSEMBLY AND INSTALLATION OF DOUBLE WALL CHIMNEY
SYSTEM
Each double wall chimney section consists of a galvanized outer pipe, a
stainless steel inner flue pipe and a wire spacer. The pipe sections must
be assembled independently as the chimney is installed. When connect-
ing chimney directly to the fireplace, the inner flue pipe section must be
installed first with the lanced side up. The outer pipe section can then
be installed over 5 the flue pipe section with the hemmed end up. Press
down on each pipe section until the lances securely engage the hem on
the fireplace starter. The wire will assure the proper spacing between the
inner and outer pipe sections.
Continue to assemble chimney sections as outlined above, making
sure that both the inner and outer pipe sections are locked together.
When installing double wall snap-lock chimney together, it is impor-
tant to assure the joint between the chimney sections is locked. Check
by pulling chimney upward after locking. The chimney will not come
apart if properly locked. It is not necessary to add screws to keep the
chimney together (exception, see Figure 10, page 10).
The height of a vertical chimney pipe supported ONLY by the fire-
place, must not exceed 20 feet. Chimney heights above 20 feet must
be supported.

FIRESTOP SPACERS (FS-10, 1100EFS-10DM FOR 36" MODELS)
Firestop spacers are required at each point where the chimney penetrates
a floor space. Their purpose is to establish and maintain the required
clearance between the chimney and the combustible materials. When
the pipe passes through a framed opening into a living space above, the
firestop must be placed onto the ceiling from below as shown in Figure 13.
They also provide complete separation from one floor space to another
or attic space as required by most codes. When the double wall pipe
passes through a framed opening into an attic space, the firestop must
be placed into an attic floor as shown in Figure 14.

IMPORTANT NOTICE
When penetrating a ceiling into an attic, a firestop
thimble (FST10) is required to avoid intrusion by insu-
lation and recommended to negotiate a joist.

Figure 14a - Firestop Thimble
PENETRATING ROOF
To maintain a 1" (36" Models) or 2" (42/50" Models) clearance to the
pipe on a roof with a pitch, a rectangular opening must be cut.
1. Determine center point through which pipe will penetrate roof.
2. Determine center point of roof. Pitch is distance the roof drops
over a given span, usually 12". A 6/12 pitch means that roof drops
6" for each 12" measured horizontally down from roof rafters.
3. Use roof opening chart (Figure 15, page 12) to determine correct
opening length and flashing required.
4. Remove shingles around opening measured. Cut out this section.
5. Add next sections of pipe until end penetrates roof line. Check
to see that proper clearances are maintained. Extend chimney by
adding sections of double wall pipe until pipe is minimum of 30"
above highest point of roof cutout. Termination and chimney must
extend a minimum of 36" above highest point where it passes
through roof.

FLASHING INSTALLATION (V6F-10DM OR V12F-10DM)
Determine the flashing to be used with the roof opening chart. Slide
flashing over pipe until base is flat against roof. Replace as many
shingles as needed to cover exposed area and flashing base. Secure
in position by nailing through shingles (see Figure 16). DO NOT NAIL
THROUGH FLASHING CONE.
Installing Flashing on a Metal Roof
When installing the flashing on a metal roof, it is required that putty
tape be used between the flashing and the roof. The flashing must be
secured to the roof using #8 x 3/4" screws and then sealed with roof
coating to prevent leakage through the screw holes. A roof coating
must also be applied around the perimeter of the flashing to provide
a proper seal.
Storm Collar Installation (SC2-1)
Place storm collar over pipe and slide down until it is snug against
the open edge of the flashing (see Figure 17). Apply waterproof caulk
around the perimeter of the collar to provide a proper seal.

FINISHING FIREPLACE
Combustible materials, such as wallboard, sheet rock, drywall, plywood,
etc. may make direct contact with sides and top around the fireplace
face. It is important that combustible materials do not overlap the face
itself. Brick, glass, tile or other noncombustible materials may overlap
the front face provided they do not obstruct essential openings like
louvered slots or any other opening. When overlapping with a noncom-
bustible facing material, use only noncombustible mortar or adhesive.

OUTSIDE AIR AND DAMPER HANDLE OPERATION
The damper handle, which opens and closes the damper blade, is
located in the upper front face of the fireplace. Pushing the handle
forward and up through the keyway slot will free damper blade to
automatically open. Pushing the handle forward and down will lock
damper blade closed (see Figure 41). Damper must be locked in the
full open position before operating fireplace (see Figure 41).
Figure 41 - Operating Damper Handle
GLASS DOORS
Glass doors are optional with the fireplace. When fireplace is in operation,
doors must be fully opened or fully closed position only or a fire hazard
may be created (see Figure 40).
A fireplace equipped with glass doors operates much differently than a
fireplace with an open front. A fireplace with glass doors has a limited
amount of air for combustion.
Excessive heat within the fireplace can result if too large a fire is built or
if combustion air gate is not completely open. The following tips should
be followed to assure that both the fireplace and glass door retain their
beauty and function properly. Both the flue damper and glass doors must
be fully opened before starting fire. This will provide sufficient combustion
air and maintain safe temperatures in firebox.
IMPORTANT: The glass must be allowed to warm slowly and evenly.
The tempered glass will withstand a gradual temperature rise to 550° F,
which is more than a normal fire will generate. Such materials as pitch/
wax laden logs, very dry mill end lumber and large amounts of paper or
cardboard boxes can create an excessively hot fire and should not be
burned in this fireplace. Always keep the fire well back from the doors
and never allow flames to contact the glass.
WARNING: Fireplaces equipped with glass doors
should be operated only with doors fully opened or
doorsfully closed. Doors, if left partly open, may draw
gas and flame out of the fireplace opening creating
risks of both fire and smoke.
WARNING: Do not slam or strike doors. Damage
can result in a hazardous condition.
WARNING: Discontinue use of the appliance imme-
diately if doors are damaged and contact a qualified
installer for repair. Only doors certified with the ap-
pliance shall be used.
Cleaning Glass
Clean glass with any commercial glass cleaner or soap and water. Do
not use any abrasive material to clean glass. Do not clean glass with any
cool water if glass is still hot from the fire and smoke.
