Sweeping Chimney Before Liner Installation?

[DeerHunter]

Hi All,

I bet I know the answer to this question, but I wanted to get people's thoughts on this because I'm a cheapskate.

Do I need to sweep my chimney before I install my liner? Here are the specifics: 6" SS Flex Liner, insulated, 18' clay tile flue (11" x 11" inside dimension). Pic attached.

Thanks for your feedback!

Absolutely yes.

Not only will it remove combustible creosote, it will keep it from stinkin'. (broken image removed)

Yes.

As clean as you can get it.
