furnace to heat an entire home. Use for supplemental heat only.
This wood burning fireplace complies with the UL 127 and ULC
S610 standards as a FACTORY BUILT FIREPLACE and is listed and
tested by the PFS Corporation.
Overfiring of a fireplace is a condition where excessive tem-
peratures are reached, beyond the design capabilities of the
appliance.Thedamagethat occursfromoverfiringisnotcovered
under the manufacturer’s limited warranty.
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, kerosene,
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
NOTusetreated wood,charcoal, coal,trash, driftwoodor woods
that have been dipped in tar, pitch, pine tar, creosote, etc.
Wood products made with synthetic binders, such as plywood,
produce abnormally high temperatures and sputtering, smoking
fires. When burning artificial logs, please read and follow the
instructions provided by the manufacturer.
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
alcohol, and those at high altitudes.
WARNING
CONTINUED OVERFIRING CAN PERMANENTLY
DAMAGE YOUR FIREPLACE SYSTEM. SOME
EXAMPLES OF CONDITIONS THAT COULD CAUSE
OVERFIRING ARE:
• BURNINGQUANTITIESOFSCRAPLUMBER,PINE
BRANCHES, PAPER OR CARDBOARD BOXES
WHICH EXCEED THE VOLUME OF THE NORMAL
LOG FIRE.
• BURNING TRASH, CHEMICALS OR CHEMICALLY
TREATED COMBUSTIBLES. VentilationRequirements-Provideadequateairforcombustion.
The fresh air requirements of this appliance 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 require-
ments in your area.
Creosote – Formation and Need for Removal
When wood is burned slowly, it produces tar and other organic
vapors,which combinewith expelledmoisture toform creosote.
The creosote vapors condense in the relatively cool chimney
ueofaslow-burningre.Asaresult,creosoteresidueaccu-
mulates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] or
more) it shall be removed to reduce the risk of a chimney fire.
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 chemicals can pose a
significant hazard.

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,

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).
