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 on the spark arrestor, it
should be cleaned or replaced to reduce the
risk of chimney fire.
4. How to Clean: have your chimney cleaned
by a professional Certified 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 to the previous chimney
section.

where coal is burned, clean the chimney
thoroughly within 48 hours of shutting down
the appliance for the season.

cleaners only as a last resort, and use only
those that the manufacturer specifically
warrants as being non-corrosive to the
chimney. Simpson Dura-Vent will assume no
liability for damage resulting from the use of
chemical cleaners.

close all possible air inlets, and call your
Fire Department. Do not use the chimney
again until it has been inspected for possible
damage.

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.

damage or roof contamination as the result
