REOSOTE ORMATION

EMOVAL
When wood is burned slowly, it produces 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.
To prevent the buildup of creosote:
1. Burn the stove with the primary air control
fully open for 30 minutes daily to burn out creosote
deposits from within the stove and the venting system.
2. After reloading with wood, burn the stove
with the primary air control fully open for 20 to 30
minutes. This manner of operation ensures early
engagement of the secondary combustion system which,
when engaged, minimizes creosote buildup in the
chimney.
The stovepipe connector and chimney should be inspected
at least monthly during the heating season to determine if
a creosote build-up has occurred. If a creosote residue
greater that 1/4" (6 mm) has accumulated, it should be
removed to reduce the risk of a chimney fire.
If your glass is remaining dirty, your operating
temperatures are low, therefore there is a higher risk of
creosote buildup.
The venting system must be inspected at the stove
connection and at the chimney top. Cooler surfaces tend
to build creosote deposits quicker, so it is important to
check the chimney at the top (where it is coolest) as well
as from the bottom near the stove.
Accumulated creosote should be removed with a cleaning
brush specifically designed for the type of chimney in use.
A certified chimney sweep should be used 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!).
It is also recommended that before each heating season
the entire system be professionally inspected, cleaned and
repaired, if necessary.

ASKETS
Gasket material should normally be replaced every two to
three seasons, depending on stove use. If the door seal is

loose, a new gasket will assure a tight seal and improved
stove performance. Contact your dealer for a gasket kit,
which includes instructions and gaskets for your stove.
The procedure for replacing gaskets on the glass is
reviewed on page 19.
To replace door gaskets, first remove the old gaskets with
a utility or putty knife. Clean all gasket channels with a
wire brush. Apply gasket cement to the channels and
push the new gas ket into place without stretching the
gasket material. The door should be shut immediately to
fully press the gasket into place and assure a positive seal.
We require the use of the following gaskets:
GLASS: 60" (152 mm) Length, 3/4" (19 mm) Wide,
Adhesive Backed Black Tape
DOOR: 60" (152 mm) Length, 3/8" (9 mm) Diameter,
Low Density Black Tube
ASH DOOR: 32" (81 mm) Length, 1/4" (6 mm)
Diameter, Low Density, Black Tube
