AUTION
Over-firing means the stove is operating at
temperatures above normal temperatures reached
during High Burns outlined in the
BURN RATE
section. Carefully avoid over-firing, as it will damage
the stove. Symptoms of chronic over-firing can
include warped components, short burn times, a
roaring sound in the stove or stovepipe, and
discoloration of the stovepipe. A properly installed
stove using fuel and following operating procedures
as outlined in this manual should not over-fire.
Excessive draft, inappropriate fuel, and operator
error can cause over-firing. Correct an over-fire
situation as follows:
•
EXCESSIVE DRAFT:
Contact your local dealer
to have a draft reading taken. Any draft in
excess of 0.1 WC requires a damper in the
stovepipe. Some installations may require more
than one damper.
•
INAPPROPRIATE FUEL:
Do not burn coal; kiln
dried lumber, wax logs, compressed wood,
highly volatile fuels or combustibles, or anything
other than natural cordwood.
•
OPERATOR ERROR:
Ensure all the gaskets
are in good condition. Replace worn out or
compressed gaskets. Only burn the stove with
the firing and ash doors in the closed position.
If you suspect your stove is over-firing, discontinue
use and contact your dealer immediately.
Damage
caused by over-firing is not covered by your
warranty.
Results of over-firing can include warped
or burned out internal parts, cracked refractory
panels, discolored or warped external parts, and
damaged finish.

SHES
You can leave a thin layer of ashes in the firebox if
preferred. Allow fire to die down or go out
completely. It is important to prevent ashes from
building up around the front door opening or they will
spill out, or they can pack into the gasket channel
and prevent proper sealing. To remove ashes, use a
fireplace shovel. Avoid removing large live coals by
pushing them to the side and removing only the finer
ash with a shovel.
Disposal of ashes - Ashes should be placed directly
into a
metal
container with a tight fitting lid. Do not
place any other items or trash into the metal
container. Do not pour water into the container.
Replace the container’s lid and allow the ashes to
cool. Never place the ash disposal container on a
combustible surface or vinyl flooring, as the
container could be
hot!
Pending disposal, place the closed ash container on
a noncombustible floor or on the ground outside,
well away from all combustible materials, liquid fuels,
or vehicles. Retain ashes in the closed container
until all coals thoroughly cool.
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.
NEVER
place ashes in wooden or plastic containers,
in trashcans with other trash, or in paper or plastic
bags, no matter how long the fire has been out.
Coals within a bed of ashes can remain hot for
several days once removed from the firebox.
