Ashes should NEVER be placed in wooden or 
plastic containers, 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.

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 and the flue bypass 
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 regularly during the heating season to 
determine if a creosote build-up has occurred. 
If a creosote residue greater than 1/4" (6 mm) 
has accumulated, it should be removed to reduce 
the risk of a chimney fire. 
 
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!).

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. 
 
To replace the fuel loading door gasket, 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 gasket 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.
