CHIMNEY MAINTENANCE 
1. Creosote and Soot: When wood is burned slowly, it produces tar and other 
organic vapors, which combine with expelled moisture to produce creosote. The 
creosote vapors conscience 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, known as a chimney fire. 
2. Access: Chimneys must be installed so that access is provided for inspection 
and cleaning. 
3. When to Clean: The chimney should be inspected at least once every month 
during the heating season to determine if creosote or soot has built up. Check 
spark arrestor screens at least every 2 to 4 weeks. If creosote or soot has 
accumulated it should be cleaned or replaced to reduce the risk of chimney fire. 
4. How to Clean: Have your chimney cleaned by a professional chimney sweep if 
you have doubts about your ability to clean it. Use a plastic/poly brush. Do not 
use a steel brush that will scratch the stainless steel liner of your chimney. Scrub 
the spark arrestor with a wire brush. To remove the Chimney Cap for cleaning, 
either twist counter-clockwise and remove the entire cap, or unscrew the 4 
screws that attach the caps support legs to the cap base. The Tee Cleanout Cap 
can be removed by turning counter-clockwise. Be sure to replace the Tee 
Cleanout Cap when you are finished cleaning the chimney. 
5. Coal: To reduce corrosion in chimneys where coal is burned, clean the chimney 
thoroughly without 48 hours of shutting down the stove for the season. 
6. Chemical Cleaners: Use chemical cleaners only as a last resort, and use only 
those which the manufacturer specifically warrants as being non corrosive to the 
chimney liner. AllFuel HST will assume no liability for damage resulting from the 
use of chemical cleaners. 
7. In Case of Fire: If a chimney fire occurs, close all appliance air inlets, and call 
your local fire department. Do NOT use the chimney again until it has been 
inspected for possible damage. 
8. Painting: As an option, you can coat all exterior metal parts, with the exception 
of the Chimney Cap, with high temperature, rust proof paint. Wash the metal 
with a vinegar and water solution before painting to remove oils. Painting the
