"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 cinders have
thoroughly cooled."
"WHEN USING THE DECORATIVE APPLIANCE, THE
FIREPLACE DAMPER MUST BE SET IN THE FULLY
OPEN POSITION."
"Neverusegasoline,gasoline-typelanternfuel,kero-
sene, charcoal lighter fluid, or similar liquids to start
or ’freshen up’ a fire in this fireplace. Keep all such
liquidswell 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,driftwoodorwoodsthathavebeendippedintar,
pitch, pine tar, creosote, etc. Wood products made
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.
WARNING: BURNING IMPROPER FUEL (I.E.
CHARCOAL) CAN RESULT IN CARBON MONOXIDE
POISONING, 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
qualified service technician. Some people are more
affected by carbon monoxide than others. These
include pregnant women, people with heart or lung
disease or anemia, those under the influence of al-
cohol, 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
fromtheheatproducedbytheappliance). Ifyourlocal

year during the heating season to determine when a
creosote buildup has occurred. When creosote has

Minimum/Maximum Chimney Height
Minimum height of chimney, measured from base of fireplace to
flue gas outlet of termination, is 14.5 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 flue
gasoutlet(seeFigure20,page12).
FRAMING
1. Frame opening for fireplace using dimensions shown in Figures
1 and 2.

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replaceandshimwithsheetmetalifnecessary.
5. Before securing fireplace to prepared framing, ember protector
must be placed between hearth extension (not included) 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included)mustbefabri-

to prevent corrosion.
6. Using screws or nails, secure fireplace to framing through flanges
located on sides of fireplace.
HEARTH EXTENSION
A hearth extension projecting a minimum of 16" in front of and a
minimum of 8" 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 = .84 BTU IN/FT2HR°F(orless)at1"
thick. For example, if 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 manu-
facturer 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 non-combustible material such
assand-cementgrout(seeFigure3,page6).

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. Pipe sections
must be assembled independently as chimney is installed. When
connecting chimney directly to fireplace, inner flue pipe section
must be installed first with lanced side up. Outer pipe section can
then be installed over flue pipe section with hemmed end up. Press
down on each pipe section until lances securely engage hem on
fireplace starter. Wire will assure proper spacing between inner
and outer pipe sections.
Note:ForCanada,usechimneypartsdesignatedHT.
Continuetoassemblechimneysectionsasoutlined,makingsure
that both inner and outer pipe sections are locked together. When
installing double wall snap-lock chimney together, it is important to
assurejointbetweenchimneysectionsislocked.Checkbypulling
chimneyupwardafterlocking.Chimneywillnotcomeapartifproperly
locked. It is not necessary to add screws to keep chimney together
(exception-seeFigure11,page10).
The height of a vertical chimney pipe supported ONLY by the fireplace,
mustnotexceed20feet.Chimneyheightsabove20feetmustbe

FIRESTOP SPACERS (3600FS-8DM-1)
Firestop spacers are required at each point where chimney penetrates
a floor space. Their purpose is to establish and maintain required
clearance between chimney and combustible materials. When pipe
passes through a framed opening into a living space above, firestop
must be placed onto ceiling from below as shown in Figure 12.
They also provide complete separation from one floor space to an-
other or attic space as required by most codes. When double wall
pipe passes through a framed opening into an attic space, firestop
must be placed into an attic floor as shown in Figure 13.
Figure 12 - Firestop Spacer with Living Space Above Ceiling
Figure 13 - Firestop Spacer with Attic Space Above Ceiling
If area above is a living space, install firestop
below framed hole.
If area above is an attic or insulated area, install
firestop above framed hole.
PENETRATING ROOF
To maintain a 1" clearance to pipe on a roof with a pitch, a rectangular
opening must be cut.
1. Determine center point where pipe will penetrate the roof.
2. Determine center point of the roof. Pitch is the distance the roof
drops over a given span, usually 12". A 6/12 pitch means that the
roof drops 6" for each 12" measure horizontally down from roof
rafters.
3. Useroofopeningchart(Figure14,page11)todeterminecorrect
