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.
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,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
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
fromtheheatproducedbytheappliance). Ifyourlocal

for requirements in your area.
Creosote – Formation and Need for Removal

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

ASSEMBLY AND INSTALLATION OF DOUBLE WALL CHIMNEY
SYSTEM
Eachdouble wall chimney section consistsof agalvanized outer
pipe,astainlesssteelinneruepipeandawirespacer.Pipesections
must be assembled independently as chimney is installed. When
connecting chimney directly to replace, inner ue pipe section
must be installed first with lanced side up. Outer pipe section can
thenbeinstalledoverue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
supported.
USING ELBOW OFFSETS (30E-8DM)
1. To achieve desired offset, you may install combinations of 12",

Note: For systems with 2 elbow sets, minimum height is 22 feet.
Maximum height for any system is 50 feet.
2. Chimney weight above offset rests on return elbow. Straps must

FIRESTOP SPACERS (3600FS-8DM-1)
Firestop spacers are required at each point where chimney penetrates
aoor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oor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oorasshowninFigure13.
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
openinglengthandashing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add-
ing 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.

CHASE INSTALLATIONS
Instructions for chase installations are included with chase style ter-
mination chosen. In a multiple chase installation, be sure to provide
adequate distance between terminations to prevent smoke spillage
from one termination to another. We suggest that terminations be
separated at least 24", center to center and stacked at a vertical height
differenceof18"(seeFigure18).
Note: If a decorative shroud is to be installed, contact manufacturer
for specifications.
10 FOOT RULE

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