EMOVAL
When wood burns slowly at low temperatures, it may
produce tar and other organic vapors, which
combine with expelled moisture to form creosote.
These 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, which may damage the chimney or even destroy
the house. When burning wood, inspect the chimney
connector and chimney at least once every two
months during the heating season to determine if
there is a creosote buildup.
If a creosote build-up occurs, inspect the stovepipe
connector and chimney more often, at least monthly
during the heating season to monitor the
accumulation. If a creosote residue greater that 1/4"
(6 mm) accumulates, remove it to reduce the risk of a
chimney fire.
Prevention
Burn the stove with the primary air control fully open
for 35 - 45 minutes daily to burn out creosote deposits
from within the stove and the venting system.
After reloading with wood, burn the stove with the
primary air control fully open for 15 to 20 minutes.
This manner of operation ensures early engagement
of the secondary combustion system that minimizes
creosote buildup in the chimney.
If your glass always remains dirty, your operating
temperatures are too low or your wood is wet;
therefore, there is a higher risk of creosote buildup.
Inspect the venting system at the stove connection
and
at the chimney top. Cooler surfaces tend to build
creosote deposits faster, so it is important to check
the chimney at the top (where it is coolest) as well as
from the bottom near the stove.
Cleaning
Remove accumulated creosote with a cleaning brush
specifically designed for the type of chimney in use.
We recommend you use a certified chimney sweep to
perform this service. Contact your dealer for the name
of a certified chimney sweep in your area (your dealer
may be a certified sweep!).
We recommend that before each heating season you
have the entire system professionally inspected,
cleaned and repaired, if necessary.

ASKETS
Replace door gasket material every two to three
seasons, or whenever it becomes deteriorated or
loose, depending on stove use. If the door seal leaks,
a new gasket will ensure a tight seal and improve
stove performance.

replacement gaskets when you need to replace your

includes instructions, and the gasket for your stove.

LASS
The glass used in our stoves is actually not plain
glass, but a tough, clear ceramic material capable of
operating at temperatures up to 2300° F. Do not
operate the stove with a broken door glass. Do not
abuse the front door by striking or slamming.
When necessary, clean the glass. For the inside
surface of the glass, we recommend using a damp
paper towel dipped in gray ash. Rub the inside of the
glass with a circular motion. When all the deposits are
removed, clean up with window cleaner or with
commercial stove glass cleaners, which are available
from your local dealer. Use this type of cleaner for the
outside surface as well. Never attempt to clean the
glass while the fire is burning or while the glass is hot.
Remove deposits by following the instructions
provided with the cleaner. Wipe the cleaner off with a
soft cloth, or black & white newsprint.
Important:
scratching or etching the glass will
weaken the integrity of the glass. Do not use a
razor blade, steel wool, or any other abrasive
material to clean the glass. Use a cleaner
specifically manufactured for woodstoves only.
The front door glass is a ceramic, thermal shock-
resistant glass, made specifically for use in
woodstoves. Do not use any replacement glass other
than the ceramic glass manufactured and supplied for
use in this woodstove. Replacement glass is available
through your local dealer.
Replace the door glass immediately if broken or
chipped. Contact your local dealer for replacement
glass. The glass kit includes instructions and
everything needed for the repair. If you replace the
glass yourself, wear work gloves and safety glasses.
