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 

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.
