Chimney Maintenance - DuraVent duraplus Installation Instructions Manual

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
every 2 to 4 weeks. If creosote or soot has
accumulated, it should be removed to reduce
the risk of chimney fire.
4. How to Clean: Have your chimney cleaned
by a certified 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 four
screws that attach the cap's support legs to
the cap base. The Tee Cleanout Cap can be
removed once the screws are unscrewed.
Remember to replace the cap 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 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. DuraVent will assume no
22
liability for damage resulting from the use of
chemical cleaners.
7. In Case of Fire: If a flue fire occurs, close
all appliance draft openings, and call your
Fire Department. Do not use the chimney
again, until it has been inspected for possible
damage.
8. Painting: To increase chimney life, 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.
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.
