"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oor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uid,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
very quickly. DO NOT use treated wood,charcoal, coal,
trash, driftwood or woods that have been dipped in tar,
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,these chemicalscan posea significanthazard.
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
monoxidepoisoningresembletheuwithheadaches,
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inuence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
from the heat produced by the appliance). If your local
code requires 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, whichcombine with expelled moisture
to form creosote. The creosote vapors condense in
the relatively cool chimney ue of a slow-burning
fire. As a result, creosote residue accumulates on
theue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
accumulated (1/8" [3 mm] ormore) it shall be removed
to reduce the risk of a chimney fire."

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).

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).

must be placed onto ceiling from below as shown in Figure 12.
They also provide complete separation from one floor space to an-
