Disposal of Ashes
Ashes should be placed in a metal container with a tight-
fittinglid. Theclosed containerofashes shouldbe 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
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.
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
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
qualifiedservicetechnician. Somepeoplearemoreaf-
fectedbycarbonmonoxidethanothers. Theseinclude
pregnant women, people with heart or lung disease
oranemia,thoseundertheinuence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
coderequiresasmoke detector be installedwithinthe
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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
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.
