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
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.
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, wood, or steel brush. Do
not use a 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, unscrew the eight
(6) screws that attach the cap to the previous
chimney section. The Tee Cleanout Cap can
be removed once the retaining bar has been
unbolted. Remember to replace the Tee
Cap and retaining bar when you are finished
cleaning the chimney.
5. Coal: To reduce corrosion in chimneys
where coal is burned, clean the chimney
thoroughly within 48 hours of shutting down
the appliance 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 noncorrosive to the chimney.
DuraVent will assume no liability for damage
resulting from the use of chemical cleaners.
7. In Case of Fire: If a flue fire occurs,
close all appliance air inlets, and call your
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. Painting the
chimney will help to increase chimney life.
9. Creosote Formation: DuraVent assumes
no liability for structural damage or roof
contamination as the result of creosote
formation. It is the owner’s responsibility
to comply with inspection and cleaning
requirements as described in these
instructions, and those of the appliance
manufacturer.
